Unlike traditional clinical trial research, Comparative Effectiveness Research seeks to determine what is 'best' for a typical patient when deciding between effective options used in daily practice - a therapy, diagnostic test, or course of action. There is a clear need for Comparative Effectiveness Research in Inflammatory Bowel Disease, a point emphasized by the Institute of Medicine and supported by governmental agencies and escalating funding. This review highlights the rationale and support for Comparative Effectiveness Research, provides examples of Comparative Effectiveness Research in Inflammatory Bowel Disease, and outlines current and future focus for Comparative Effectiveness Research in Inflammatory Bowel Disease.

Graduating nursing students are expected to have acquired the necessary skills to provide research-based care to patients. However, recent studies have shown that new graduate nurses report their extent of research use as relatively low. Because behavior intention is a well-known predictor of subsequent behavior, this gives reasons to further investigate graduating nursing students' intentions to use research in clinical practice after undergraduate study. To investigate graduating nursing students' intentions to use research in clinical practice and, furthermore, to investigate whether intention in itself and as a mediating variable can predict subsequent research use behavior in clinical practice one year post graduation. A follow-up study was performed of graduating nursing students in their final semester of undergraduate study (2006) and at one year post graduation (2008). Data were collected within the larger national survey LANE (Longitudinal Analysis of Nursing Education). A sample of 1319 respondents was prospectively followed. Graduating nursing students' intentions to use research instrumentally were studied as a predictor of their subsequent instrumental research use one year post graduation. A statistical full mediation model was tested to evaluate the effects of intention and factors from undergraduate study on subsequent research use in daily care. Thirty-four percent of the nursing students intended to use research on more than half or almost every working shift in their future clinical practice. Intention showed a direct effect on research use behavior. In addition, significant indirect effects on research use were shown for capability beliefs (regarding practicing the principles of evidence-based practice) and perceived support for research use (from campus and clinical education), where intention acted as a mediating factor for those effects. Students rated a modest level of intention to use research evidence. Intentions close to graduation acted as an essential predictor of subsequent research use behavior, both through a direct effect and as a mediating variable. These findings give support for designing future interventions aiming at influencing students' intention to use research to improve subsequent behavior. Focusing on strengthening students' capability beliefs and providing support for research use appear as promising target activities. Copyright © 2012 Elsevier Ltd. All rights reserved.

Community engagement has been recognised as an important aspect of the ethical conduct of biomedical research, especially when research is focused on ethnically or culturally distinct populations. While this is a generally accepted tenet of biomedical research, it is unclear what components are necessary for effective community engagement, particularly in the context of genomic research in Africa. We conducted a review of the published literature to identify the community engagement strategies that can support the successful implementation of genomic studies in Africa. Our search strategy involved using online databases, Pubmed (National Library of Medicine), Medline and Google scholar. Search terms included a combination of the following: community engagement, community advisory boards, community consultation, community participation, effectiveness, genetic and genomic research, Africa, developing countries. A total of 44 articles and 1 thesis were retrieved of which 38 met the selection criteria. Of these, 21 were primary studies on community engagement, while the rest were secondary reports on community engagement efforts in biomedical research studies. 34 related to biomedical research generally, while 4 were specific to genetic and genomic research in Africa. We concluded that there were several community engagement strategies that could support genomic studies in Africa. While many of the strategies could support the early stages of a research project such as the recruitment of research participants, further research is needed to identify effective strategies to engage research participants and their communities beyond the participant recruitment stage. Research is also needed to address how the views of local communities should be incorporated into future uses of human biological samples. Finally, studies evaluating the impact of CE on genetic research are lacking. Systematic evaluation of CE strategies is essential to determine the most effective models of CE for genetic and genomic research conducted in African settings.

A 3 year update on the influence of noise on performance and behavior.

PubMed

Clark, Charlotte; Sörqvist, Patrik

2012-01-01

The effect of noise exposure on human performance and behavior continues to be a focus for research activities. This paper reviews developments in the field over the past 3 years, highlighting current areas of research, recent findings, and ongoing research in two main research areas: Field studies of noise effects on children's cognition and experimental studies of auditory distraction. Overall, the evidence for the effects of external environmental noise on children's cognition has strengthened in recent years, with the use of larger community samples and better noise characterization. Studies have begun to establish exposure-effect thresholds for noise effects on cognition. However, the evidence remains predominantly cross-sectional and future research needs to examine whether sound insulation might lessen the effects of external noise on children's learning. Research has also begun to explore the link between internal classroom acoustics and children's learning, aiming to further inform the design of the internal acoustic environment. Experimental studies of the effects of noise on cognitive performance are also reviewed, including functional differences in varieties of auditory distraction, semantic auditory distraction, individual differences in susceptibility to auditory distraction, and the role of cognitive control on the effects of noise on understanding and memory of target speech materials. In general, the results indicate that there are at least two functionally different types of auditory distraction: One due to the interruption of processes (as a result of attention being captured by the sound), another due to interference between processes. The magnitude of the former type is related to individual differences in cognitive control capacities (e.g., working memory capacity); the magnitude of the latter is not. Few studies address noise effects on behavioral outcomes, emphasizing the need for researchers to explore noise effects on behavior in more detail.

2015-01-01

To examine the impact of research design on results in two published comparative effectiveness studies. Guidelines for comparative effectiveness research have recommended incorporating disease process in study design. Based on the recommendations, we develop a checklist of considerations and apply the checklist in review of two published studies on comparative effectiveness of colony-stimulating factors. Both studies used similar administrative claims data, but different methods, which resulted in directionally different estimates. Major design differences between the two studies include: whether the timing of intervention in disease process was identified and whether study cohort and outcome assessment period were defined based on this temporal relationship. Disease process and timing of intervention should be incorporated into the design of comparative effectiveness studies.

Researchers' Intuitions About Power in Psychological Research.

PubMed

Bakker, Marjan; Hartgerink, Chris H J; Wicherts, Jelte M; van der Maas, Han L J

2016-08-01

Many psychology studies are statistically underpowered. In part, this may be because many researchers rely on intuition, rules of thumb, and prior practice (along with practical considerations) to determine the number of subjects to test. In Study 1, we surveyed 291 published research psychologists and found large discrepancies between their reports of their preferred amount of power and the actual power of their studies (calculated from their reported typical cell size, typical effect size, and acceptable alpha). Furthermore, in Study 2, 89% of the 214 respondents overestimated the power of specific research designs with a small expected effect size, and 95% underestimated the sample size needed to obtain .80 power for detecting a small effect. Neither researchers' experience nor their knowledge predicted the bias in their self-reported power intuitions. Because many respondents reported that they based their sample sizes on rules of thumb or common practice in the field, we recommend that researchers conduct and report formal power analyses for their studies. © The Author(s) 2016.

Applications of pain-related evoked potentials and short-latency somatosensory evoked potentials in acupuncture research: a narrative review.

2015-10-01

To review and discuss the Chinese and English literature on the use of pain-related evoked potentials (PREP) and short-latency somatosensory EP (SLSEP) in acupuncture research. China National Knowledge Infrastructure Database and MEDLINE were searched for the following key words: acupuncture and PREP or SLSEP. Thirty-seven articles were included in the review. Researchers usually use PREPs to study the analgesic effect of acupuncture, observe influential factors, or for mechanistic exploration. In the SLSEP studies, researchers focused on response characteristics of acupuncture, acupoint specificity, and influential factors of the treatment. There were some problems with the study design and conclusions. Researchers could use PREP and SLSEP to objectively validate the effects of acupuncture and explore its mechanisms using nerve electrophysiology. Further studies can benefit from observing more acupoints' effects using PREPs or SLSEPs and investigating the placebo effect of acupuncture.

Interventions for improving the research literacy of nurses: a systematic review.

PubMed

Hines, Sonia; Ramsbotham, Joanne; Coyer, Fiona

2016-02-01

Despite the importance of research literacy for nurses, many nurses report feeling unable to effectively read and understand research, which in turn results in lower research utilization in practice. Nurses themselves identify poor experiences with trying to understand and use research as factors that contribute to a reluctance to utilize research. This reluctance often leads nurses to seek other sources of information, such as colleagues, instead. The objective of this review was to identify the effectiveness of research literacy interventions on the research literacy of registered nurses. Registered nurses.Interventions of interest were those that evaluated the effectiveness of workplace educational programs or interventions conducted in a healthcare organization or tertiary-level educational facility aiming to improve or increase registered nurses' understanding of research literature.Outcomes of interest were research literacy, measured explicitly or as research knowledge, research understanding, use of research evidence in practice, and/or ability to critically appraise research.We considered experimental study designs such as randomized controlled trials, nonrandomized controlled trials, quasi-experimental, and before and after studies. A wide range of databases were searched in order to provide the most complete possible review of the evidence. Initial keywords used were: "research litera*", "research education", "research knowledge", "evidence-based practice education". Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI). Data were extracted from papers included in the review using the standardized data extraction tool from JBI-MAStARI. Quantitative data would have been, if possible, pooled in statistical meta-analysis using the Cochrane Collaboration's Review Manager 5.2 software. As statistical pooling was not possible, the findings are presented in narrative form including tables and figures where appropriate to aid in data presentation. The majority of included studies were single-group pre-test/post-test designs (n=7). One was a post-test only two-group comparison and two were two-group quasi-experimental studies. Included studies were conducted in Taiwan, Japan, Hong Kong, Australia, United Kingdom and United States. The total number of registered nurses in the included studies was 453. The educational interventions were conducted in universities (n=6) and healthcare facilities (n=4). Most included studies were published (n=9), with one unpublished study. The evidence on educational interventions, while not strong, is indicative of the types of interventions which are likely to be effective. Online or face-to-face interventions using interactive teaching strategies, such as activities, role-play and discussions, and which are underpinned by an appropriate behavioral or education theory, are likely to increase research literacy. More rigorous experimental studies of educational interventions for nurses' research literacy are warranted, in order to demonstrate the effectiveness of different course and program designs. Future studies should consider longer periods of follow-up to test the longevity of the effect, as education needs to have lasting effects to be beneficial to the recipients.

The US federal framework for research on endocrine disrupters and an analysis of research programs supported during fiscal year 1996

The potential health and ecological effects of endocrine disrupting chemicals has become a high visibility environmental issue. The 1990s have witnessed a growing concern, both on the part of the scientific community and the public, that environmental chemicals may be causing widespread effects in humans and in a variety of fish and wildlife species. This growing concern led the Committee on the Environment and Natural Resources (CENR) of the National Science and Technology Council to identify the endocrine disrupter issue as a major research initiative in early 1995 and subsequently establish an ad hoc Working Group on Endocrine Disrupters. The objectives of the working group are to 1) develop a planning framework for federal research related to human and ecological health effects of endocrine disrupting chemicals; 2) conduct an inventory of ongoing federal research programs; and 3) identify research gaps and develop a coordinated interagency plan to address priority research needs. This communication summarizes the activities of the federal government in defining a common framework for planning an endocrine disrupter research program and in assessing the status of the current effort. After developing the research framework and compiling an inventory of active research projects supported by the federal government in fiscal year 1996, the CENR working group evaluated the current federal effort by comparing the ongoing activities with the research needs identified in the framework. The analysis showed that the federal government supports considerable research on human health effects, ecological effects, and exposure assessment, with a predominance of activity occurring under human health effects. The analysis also indicates that studies on reproductive development and carcinogenesis are more prevalent than studies on neurotoxicity and immunotoxicity, that mammals (mostly laboratory animals) are the main species under study, and that chlorinated dibenzodioxins and polychlorinated biphenyls are the most commonly studied chemical classes. Comparison of the inventory with the research needs should allow identification of underrepresented research areas in need of attention.

Efficacy methods to evaluate health communication and marketing campaigns.

PubMed

Evans, W Douglas; Uhrig, Jennifer; Davis, Kevin; McCormack, Lauren

2009-06-01

Communication and marketing are growing areas of health research, but relatively few rigorous efficacy studies have been conducted in these fields. In this article, we review recent health communication and marketing efficacy research, present two case studies that illustrate some of the considerations in making efficacy design choices, and advocate for greater emphasis on rigorous health communication and marketing efficacy research and the development of a research agenda. Much of the outcomes research in health communication and marketing, especially mass media, utilizes effectiveness designs conducted in real time, in the media markets or communities in which messages are delivered. Such evaluations may be impractical or impossible, however, imiting opportunities to advance the state of health communication and marketing research and the knowledge base on effective campaign strategies, messages, and channels. Efficacy and effectiveness studies use similar measures of behavior change. Efficacy studies, however, offer greater opportunities for experimental control, message exposure, and testing of health communication and marketing theory. By examining the literature and two in-depth case studies, we identify advantages and limitations to efficacy studies. We also identify considerations for when to adopt efficacy and effectiveness methods, alone or in combination. Finally, we outline a research agenda to investigate issues of internal and external validity, mode of message presentation, differences between marketing and message strategies, and behavioral outcomes.

The Use of Social Media in Recruitment for Medical Research Studies: A Scoping Review

PubMed Central

2016-01-01

Background Recruiting an adequate number of participants into medical research studies is challenging for many researchers. Over the past 10 years, the use of social media websites has increased in the general population. Consequently, social media websites are a new, powerful method for recruiting participants into such studies. Objective The objective was to answer the following questions: (1) Is the use of social media more effective at research participant recruitment than traditional methods? (2) Does social media recruit a sample of research participants comparable to that recruited via other methods? (3) Is social media more cost-effective at research participant recruitment than traditional methods? Methods Using the MEDLINE, PsycINFO, and EMBASE databases, all medical research studies that used social media and at least one other method for recruitment were identified. These studies were then categorized as either interventional studies or observational studies. For each study, the effectiveness of recruitment, demographic characteristics of the participants, and cost-effectiveness of recruitment using social media were evaluated and compared with that of the other methods used. The social media sites used in recruitment were identified, and if a study stated that the target population was “difficult to reach” as identified by the authors of the study, this was noted. Results Out of 30 studies, 12 found social media to be the most effective recruitment method, 15 did not, and 3 found social media to be equally effective as another recruitment method. Of the 12 studies that found social media to be the best recruitment method, 8 were observational studies while 4 were interventional studies. Of the 15 studies that did not find social media to be the best recruitment method, 7 were interventional studies while 8 were observational studies. In total, 8 studies stated that the target population was “hard-to-reach,” and 6 of these studies found social media to be the most effective recruitment method. Out of 14 studies that reported demographic data for participants, 2 studies found that social media recruited a sample comparable to that recruited via traditional methods and 12 did not. Out of 13 studies that reported cost-effectiveness, 5 studies found social media to be the most cost-effective recruitment method, 7 did not, and 1 study found social media equally cost-effective as compared with other methods. Conclusions Only 12 studies out of 30 found social media to be the most effective recruitment method. There is evidence that social media can be the best recruitment method for hard-to-reach populations and observational studies. With only 30 studies having compared recruitment through social media with other methods, more studies need to be done that report the effectiveness of recruitment for each strategy, demographics of participants recruited, and cost-effectiveness of each method.

2015-01-01

While randomized controlled trials (RCTs) are the gold standard for research, many research questions cannot be ethically and practically answered using an RCT. Comparative effectiveness research (CER) techniques are often better suited than RCTs to address the effects of an intervention under routine care conditions, an outcome otherwise known as effectiveness. CER research techniques covered in this section include: effectiveness-oriented experimental studies such as pragmatic trials and cluster randomized trials, treatment response heterogeneity, observational and database studies including adjustment techniques such as sensitivity analysis and propensity score analysis, systematic reviews and meta-analysis, decision analysis, and cost effectiveness analysis. Each section describes the technique and covers the strengths and weaknesses of the approach.

2017-02-01

In recent years, evidence has emerged regarding the effectiveness of osteopathic manipulative treatments (OMT). Despite growing evidence in this field, there is need for appropriate research designs that effectively reflect the person-centred system of care promoted in osteopathy and provide data which can inform policy decisions within the healthcare system. The purpose of this systematic review is to identify, appraise and synthesise the evidence from comparative effectiveness and economic evaluation research involving OMT. A database search was conducted using CINAHL, PubMed, PEDro, AMED, SCOPUS and OSTMED.DR, from their inception to May 2015. Two separate searches were undertaken to identify original research articles encompassing the economic evaluation and comparative effectiveness of OMT. Identified comparative effectives studies were evaluated using the Cochrane risk of bias tool and appraised using the Good Reporting of Comparative Effectiveness (GRACE) principles. Identified economic studies were assessed with the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) guidelines. Sixteen studies reporting the findings of comparative effectiveness (n = 9) and economic evaluation (n = 7) research were included. The comparative effectiveness studies reported outcomes for varied health conditions and the majority (n = 6) demonstrated a high risk of bias. The economic evaluations included a range of analyses and considerable differences in the quality of reporting were evident. Despite some positive findings, published comparative effectiveness and health economic studies in OMT are of insufficient quality and quantity to inform policy and practice. High quality, well-designed, research that aligns with international best practice is greatly needed to build a pragmatic evidence base for OMT. Copyright © 2016 Elsevier Ltd. All rights reserved.

Heyvaert, M; Maes, B; Van den Noortgate, W; Kuppens, S; Onghena, P

2012-01-01

The effectiveness of different interventions for challenging behavior (CB) in persons with intellectual disabilities (ID) was reviewed by means of a two-phase study. First, a systematic review of 137 meta-analyses and reviews on group-study interventions for CB in persons with ID was conducted. Based on this review, hypotheses concerning the effectiveness of divergent interventions for CB and concerning the impact of variables moderating treatment effectiveness were systematically generated. Second, these hypotheses were tested by means of a multilevel meta-analysis of single-case and small-n research. Two hundred and eighty-five studies reporting on 598 individuals were examined. The average treatment effect was large and statistically significant. However, this effect varied significantly over the included studies and participants. Compared to the meta-analyses and reviews focusing on group-studies in this research domain, the results of the present multilevel meta-analysis of single-case and small-n intervention research provided more detailed knowledge on which specific CB and intervention components moderate the interventions' effectiveness.

To synthesize the substance-dependence researches focusing on rehab treatment phase. Several criteria were used to select studies for meta analysis. Firstly, the research must have focused on the rehab period on the substance-dependence treatment, secondly, only quantitative researches that used statistics to calculate effect sizes were selected, and thirdly, all researches were from Thai libraries and were done during 1997-2006. The instrument used for data collection was comprised of two sets. The first used to collect the general information of studies including the crucial statistics and test statistics. The second was used to assess the quality of studies. Results from synthesizing 32 separate studies found that 323 effect sizes were computed in terms of the correlation coefficient "r". The psychology approach rehab program was higher in effect size than the network approach (p < 0.05). Additionally, Quasi-experimental studies were higher in effect size than correlation studies (p < 0.05). Among the quasi-experimental studies it was found that TCs revealed the highest effect size (r = 0.76). Among the correlation studies, it was found that the motivation program revealed the highest effect size (r = 0.84). The substance-use rehab treatment programs in Thailand which revealed the high effect size should be adjusted to the current program. However, the narcotic studies which focus on the rehab phase should be synthesized every 5-10 years in order to integrate new concept into the development of future the substance-dependence rehab treatment program, especially those at the research unit of the Drug Dependence Treatment Institute/Centers in Thailand.

Research funds are limited and a healthcare profession that supports research activity should establish research priority areas. The study objective was to identify research priority areas for the Canadian chiropractic profession, and for stakeholders in the chiropractic profession to rank these in order of importance. We conducted a modified Delphi consensus study between August 2015 and May 2017 to determine the views of Canadian chiropractic organisations (e.g. Canadian Chiropractic Association; provincial associations) and stakeholder groups (e.g. chiropractic educational institutions; researchers). Participants completed three online Delphi survey rounds. In Round 1, participants suggested research areas within four broad research themes: 1) Basic science; 2) Clinical; 3) Health services; and 4) Population health. In Round 2, researchers created sub-themes by categorising the areas suggested in Round 1, and participants judged the importance of the research sub-themes. We defined consensus as at least 70% of participants agreeing that a research area was "essential" or "very important". In Round 3, results from Round 2 were presented to the participants to re-evaluate the importance of sub-themes. Finally, participants completed an online pairwise ranking activity to determine the rank order of the list of important research sub-themes. Fifty-seven participants, of 85 people invited, completed Round 1 (response rate 67%). Fifty-six participants completed Round 2, 55 completed Round 3, and 53 completed the ranking activity. After three Delphi rounds and the pairwise ranking activity was completed, the ranked list of research sub-themes considered important were: 1) Integration of chiropractic care into multidisciplinary settings; 2) Costs and cost-effectiveness of chiropractic care; 3) Effect of chiropractic care on reducing medical services; 4) Effects of chiropractic care; 5) Safety/side effects of chiropractic care; 6) Chiropractic care for older adults; 7) Neurophysiological mechanisms and effects of spinal manipulative therapy; 8) General mechanisms and effects of spinal manipulative therapy. This project identified research priority areas for the Canadian chiropractic profession.

The goal of comparative effectiveness analysis is to examine the relationship between two variables, treatment, or exposure and effectiveness or outcome. Unlike data obtained through randomized controlled trials, researchers face greater challenges with causal inference with observational studies. Recognizing these challenges, a task force was formed to develop a guidance document on methodological approaches to addresses these biases. The task force was commissioned and a Chair was selected by the International Society for Pharmacoeconomics and Outcomes Research Board of Directors in October 2007. This report, the second of three reported in this issue of the Journal, discusses the inherent biases when using secondary data sources for comparative effectiveness analysis and provides methodological recommendations to help mitigate these biases. The task force report provides recommendations and tools for researchers to mitigate threats to validity from bias and confounding in measurement of exposure and outcome. Recommendations on design of study included: the need for data analysis plan with causal diagrams; detailed attention to classification bias in definition of exposure and clinical outcome; careful and appropriate use of restriction; extreme care to identify and control for confounding factors, including time-dependent confounding. Design of nonrandomized studies of comparative effectiveness face several daunting issues, including measurement of exposure and outcome challenged by misclassification and confounding. Use of causal diagrams and restriction are two techniques that can improve the theoretical basis for analyzing treatment effects in study populations of more homogeneity, with reduced loss of generalizability.

Comparative effectiveness research (CER) is intended to inform decision making in clinical practice, and is central to patient-centered outcomes research (PCOR). To summarize key aspects of CER definitions and provide examples highlighting the complementary nature of efficacy and CER studies in pulmonary, critical care, and sleep medicine. An ad hoc working group of the American Thoracic Society with experience in clinical trials, health services research, quality improvement, and behavioral sciences in pulmonary, critical care, and sleep medicine was convened. The group used an iterative consensus process, including a review by American Thoracic Society committees and assemblies. The traditional efficacy paradigm relies on clinical trials with high internal validity to evaluate interventions in narrowly defined populations and in research settings. Efficacy studies address the question, "Can it work in optimal conditions?" The CER paradigm employs a wide range of study designs to understand the effects of interventions in clinical settings. CER studies address the question, "Does it work in practice?" The results of efficacy and CER studies may or may not agree. CER incorporates many attributes of outcomes research and health services research, while placing greater emphasis on meeting the expressed needs of nonresearcher stakeholders (e.g., patients, clinicians, and others). CER complements traditional efficacy research by placing greater emphasis on the effects of interventions in practice, and developing evidence to address the needs of the many stakeholders involved in health care decisions. Stakeholder engagement is an important component of CER.

Clinical effectiveness of a cognitive behavioral group treatment program for anxiety disorders: a benchmarking study.

PubMed

Oei, Tian P S; Boschen, Mark J

2009-10-01

Previous research has established efficacy of cognitive behavioral therapy (CBT) for anxiety disorders, yet it has not been widely assessed in routine community clinic practices. Efficacy research sacrifices external validity to achieve maximum internal validity. Recently, effectiveness research has been advocated as more ecologically valid for assessing routine clinical work in community clinics. Furthermore, there is a lack of effectiveness research in group CBT. This study aims to extend existing research on the effectiveness of CBT from individual therapy into group therapy delivery. It aimed also to examine outcome using not only symptom measures, but also measures of related symptoms, cognitions, and life quality and satisfaction. Results from a cohort of patients with various anxiety disorders demonstrated that treatment was effective in reducing anxiety symptoms to an extent comparable with other effectiveness studies. Despite this, only 43% of individuals showed reliable change, and 17% were 'recovered' from their anxiety symptoms, and the post-treatment measures were still significantly different from the level of anxiety symptoms observed in the general population.

Improper practices and unprofessional conduct in clinical research have been shown to waste a significant portion of healthcare funds and harm public health. Our objective was to evaluate the effectiveness of educational or policy interventions in research integrity or responsible conduct of research on the behaviour and attitudes of researchers in health and other research areas. We searched the CENTRAL, MEDLINE, LILACS and CINAHL health research bibliographical databases, as well as the Academic Search Complete, AGRICOLA, GeoRef, PsycINFO, ERIC, SCOPUS and Web of Science databases. We performed the last search on 15 April 2015 and the search was limited to articles published between 1990 and 2014, inclusive. We also searched conference proceedings and abstracts from research integrity conferences and specialized websites. We handsearched 14 journals that regularly publish research integrity research. We included studies that measured the effects of one or more interventions, i.e. any direct or indirect procedure that may have an impact on research integrity and responsible conduct of research in its broadest sense, where participants were any stakeholders in research and publication processes, from students to policy makers. We included randomized and non-randomized controlled trials, such as controlled before-and-after studies, with comparisons of outcomes in the intervention versus non-intervention group or before versus after the intervention. Studies without a control group were not included in the review. We used the standard methodological procedures expected by Cochrane. To assess the risk of bias in non-randomized studies, we used a modified Cochrane tool, in which we used four out of six original domains (blinding, incomplete outcome data, selective outcome reporting, other sources of bias) and two additional domains (comparability of groups and confounding factors). We categorized our primary outcome into the following levels: 1) organizational change attributable to intervention, 2) behavioural change, 3) acquisition of knowledge/skills and 4) modification of attitudes/perceptions. The secondary outcome was participants' reaction to the intervention. Thirty-one studies involving 9571 participants, described in 33 articles, met the inclusion criteria. All were published in English. Fifteen studies were randomized controlled trials, nine were controlled before-and-after studies, four were non-equivalent controlled studies with a historical control, one was a non-equivalent controlled study with a post-test only and two were non-equivalent controlled studies with pre- and post-test findings for the intervention group and post-test for the control group. Twenty-one studies assessed the effects of interventions related to plagiarism and 10 studies assessed interventions in research integrity/ethics. Participants included undergraduates, postgraduates and academics from a range of research disciplines and countries, and the studies assessed different types of outcomes.We judged most of the included randomized controlled trials to have a high risk of bias in at least one of the assessed domains, and in the case of non-randomized trials there were no attempts to alleviate the potential biases inherent in the non-randomized designs.We identified a range of interventions aimed at reducing research misconduct. Most interventions involved some kind of training, but methods and content varied greatly and included face-to-face and online lectures, interactive online modules, discussion groups, homework and practical exercises. Most studies did not use standardized or validated outcome measures and it was impossible to synthesize findings from studies with such diverse interventions, outcomes and participants. Overall, there is very low quality evidence that various methods of training in research integrity had some effects on participants' attitudes to ethical issues but minimal (or short-lived) effects on their knowledge. Training about plagiarism and paraphrasing had varying effects on participants' attitudes towards plagiarism and their confidence in avoiding it, but training that included practical exercises appeared to be more effective. Training on plagiarism had inconsistent effects on participants' knowledge about and ability to recognize plagiarism. Active training, particularly if it involved practical exercises or use of text-matching software, generally decreased the occurrence of plagiarism although results were not consistent. The design of a journal's author contribution form affected the truthfulness of information supplied about individuals' contributions and the proportion of listed contributors who met authorship criteria. We identified no studies testing interventions for outcomes at the organizational level. The numbers of events and the magnitude of intervention effects were generally small, so the evidence is likely to be imprecise. No adverse effects were reported. The evidence base relating to interventions to improve research integrity is incomplete and the studies that have been done are heterogeneous, inappropriate for meta-analyses and their applicability to other settings and population is uncertain. Many studies had a high risk of bias because of the choice of study design and interventions were often inadequately reported. Even when randomized designs were used, findings were difficult to generalize. Due to the very low quality of evidence, the effects of training in responsible conduct of research on reducing research misconduct are uncertain. Low quality evidence indicates that training about plagiarism, especially if it involves practical exercises and use of text-matching software, may reduce the occurrence of plagiarism.

Technology Commercialization Effects on the Conduct of Research in Higher Education

Powers, Joshua B.; Campbell, Eric G.

2012-01-01

The objective of this study was to investigate the effects of technology commercialization on researcher practice and productivity at U.S. universities. Using data drawn from licensing contract documents and databases of university-industry linkages and faculty research output, the study findings suggest that the common practice of licensing technologies exclusively to singular firms may have a dampening effect on faculty inventor propensity to conduct published research and to collaborate with others on research. Furthermore, faculty who are more actively engaged in patenting may be less likely to collaborate with outsiders on research while faculty at public universities may experience particularly strong norms to engage in commercialization vis-à-vis traditional routes to research dissemination. These circumstances appear to be hindering innovation via the traditional mechanisms (research publication and collaboration), questioning the success of policymaking to date for the purpose of speeding the movement of research from the lab bench to society.

Reproducibility of preclinical animal research improves with heterogeneity of study samples

Vogt, Lucile; Sena, Emily S.; Würbel, Hanno

2018-01-01

Single-laboratory studies conducted under highly standardized conditions are the gold standard in preclinical animal research. Using simulations based on 440 preclinical studies across 13 different interventions in animal models of stroke, myocardial infarction, and breast cancer, we compared the accuracy of effect size estimates between single-laboratory and multi-laboratory study designs. Single-laboratory studies generally failed to predict effect size accurately, and larger sample sizes rendered effect size estimates even less accurate. By contrast, multi-laboratory designs including as few as 2 to 4 laboratories increased coverage probability by up to 42 percentage points without a need for larger sample sizes. These findings demonstrate that within-study standardization is a major cause of poor reproducibility. More representative study samples are required to improve the external validity and reproducibility of preclinical animal research and to prevent wasting animals and resources for inconclusive research.

2009-01-01

Objective There is a growing consensus that there is a need to test the real-world effectiveness of eating disorder therapies that show promise in efficacy research. The current paper provides a narrative account of an NIMH-funded study that attempted to apply efficacy findings from CBT research to an Intensive Outpatient Program (IOP) at the largest community-based eating disorder program in the United States. Method We describe the study as originally envisioned as well as the various challenges that the researchers and the IOP staff encountered in implementing this study. Results The different training, assumptions, and “ways of knowing” of the research team and the treatment staff in regard to the nature of eating disorders and their treatment created multiple challenges for both groups during the study period. We describe valuable lessons learned about how to - and how not to -implement effectiveness designs in clinical settings that are relatively unfamiliar with empirically-based research findings. Discussion It is hoped that our experience in attempting to apply efficacy-based research findings on eating disorders treatment in a community-based clinical setting will prove helpful to other researchers and service providers engaging in such translational research.

Comparative effectiveness research in cancer with observational data.

PubMed

Giordano, Sharon H

2015-01-01

Observational studies are increasingly being used for comparative effectiveness research. These studies can have the greatest impact when randomized trials are not feasible or when randomized studies have not included the population or outcomes of interest. However, careful attention must be paid to study design to minimize the likelihood of selection biases. Analytic techniques, such as multivariable regression modeling, propensity score analysis, and instrumental variable analysis, also can also be used to help address confounding. Oncology has many existing large and clinically rich observational databases that can be used for comparative effectiveness research. With careful study design, observational studies can produce valid results to assess the benefits and harms of a treatment or intervention in representative real-world populations.

Instrumental variable methods in comparative safety and effectiveness research.

PubMed

Brookhart, M Alan; Rassen, Jeremy A; Schneeweiss, Sebastian

2010-06-01

Instrumental variable (IV) methods have been proposed as a potential approach to the common problem of uncontrolled confounding in comparative studies of medical interventions, but IV methods are unfamiliar to many researchers. The goal of this article is to provide a non-technical, practical introduction to IV methods for comparative safety and effectiveness research. We outline the principles and basic assumptions necessary for valid IV estimation, discuss how to interpret the results of an IV study, provide a review of instruments that have been used in comparative effectiveness research, and suggest some minimal reporting standards for an IV analysis. Finally, we offer our perspective of the role of IV estimation vis-à-vis more traditional approaches based on statistical modeling of the exposure or outcome. We anticipate that IV methods will be often underpowered for drug safety studies of very rare outcomes, but may be potentially useful in studies of intended effects where uncontrolled confounding may be substantial.

Confidence crisis of results in biomechanics research.

PubMed

Knudson, Duane

2017-11-01

Many biomechanics studies have small sample sizes and incorrect statistical analyses, so reporting of inaccurate inferences and inflated magnitude of effects are common in the field. This review examines these issues in biomechanics research and summarises potential solutions from research in other fields to increase the confidence in the experimental effects reported in biomechanics. Authors, reviewers and editors of biomechanics research reports are encouraged to improve sample sizes and the resulting statistical power, improve reporting transparency, improve the rigour of statistical analyses used, and increase the acceptance of replication studies to improve the validity of inferences from data in biomechanics research. The application of sports biomechanics research results would also improve if a larger percentage of unbiased effects and their uncertainty were reported in the literature.

This article reviews 35 drug abuse prevention program evaluations employing drug-specific outcome measures. Many of these evaluations assessed the effects of "new generation" prevention strategies: affective, peer-oriented, and multidimensional approaches. Only 14 studies evaluated purely informational programs. Evaluations were analyzed to ascertain (1) characteristics of the programs under study, (2) characteristics of the research designs, and (3) patterns among findings. This review provides some evidence that the newer prevention strategies may produce more positive and fewer negative outcomes than did older drug information approaches. Over 70% of the programs using the newer strategies produced some positive effects; only 29% showed negative effects. In contrast, 46% of informational programs showed positive effects; 46% showed negative effects. These findings must be approached with great caution, since the research was frequently scientifically inadequate, and since rigor of research was negatively correlated with intensity and duration of program services.

Decline in placebo-controlled trial results suggests new directions for comparative effectiveness research.

PubMed

Olfson, Mark; Marcus, Steven C

2013-06-01

The Affordable Care Act offers strong support for comparative effectiveness research, which entails comparisons among active treatments, to provide the foundation for evidence-based practice. Traditionally, a key form of research into the effectiveness of therapeutic treatments has been placebo-controlled trials, in which a specified treatment is compared to placebo. These trials feature high-contrast comparisons between treatments. Historical trends in placebo-controlled trials have been evaluated to help guide the comparative effectiveness research agenda. We investigated placebo-controlled trials reported in four leading medical journals between 1966 and 2010. We found that there was a significant decline in average effect size or average difference in efficacy (the ability to produce a desired effect) between the active treatment and placebo. On average, recently studied treatments offered only small benefits in efficacy over placebo. A decline in effect sizes in conventional placebo-controlled trials supports an increased emphasis on other avenues of research, including comparative studies on the safety, tolerability, and cost of treatments with established efficacy.

To examine the effectiveness of a planned rapid recruitment strategy in an osteoporosis clinical trial. Multiple recruitment methods were explored, including media advertising, searching bone density scan and X-ray results in specialist and primary practice databases, community initiatives, and generation of research centre and study-specific pamphlets. Of 246 women screened, 41 consenting to the study, only 14 were randomised. Thus, 232 (94%) volunteers were screen failures, ineligible or declined to participate. With regard to the cost-effectiveness of all recruitment strategies, searching the research centre database was the most successful, with four women randomised at a cost of approximately NZ$302 per volunteer. Other strategies were less cost-effective. Obtaining a specific study cohort can be achieved by a comprehensive, targeted, rapid recruitment program. A research centre database search was the most successful and cost-effective recruitment modality in this small study. © 2012 Canterbury Geriatric Medical Research Trust.

The recent recession and lingering high unemployment will likely lead to a burst of research studying the health effects of economic decline. We aim to inform that work by summarizing empirical research concerned with those effects. We separate the studies into groups defined by questions asked, mechanisms invoked, and outcomes studied. We conclude that although much research shows that undesirable job and financial experiences increase the risk of psychological and behavioral disorder, many other suspected associations remain poorly studied or unsupported. The intuition that mortality increases when the economy declines, for example, appears wrong. We note that the research informs public health programming by identifying risk factors, such as job loss, made more frequent by economic decline. The promise that the research would identify health costs and benefits of economic policy choices, however, remains unfulfilled and will likely remain so without stronger theory and greater methodological agreement.

Researchers' choice of the number and range of levels in experiments affects the resultant variance-accounted-for effect size.

PubMed

Okada, Kensuke; Hoshino, Takahiro

2017-04-01

In psychology, the reporting of variance-accounted-for effect size indices has been recommended and widely accepted through the movement away from null hypothesis significance testing. However, most researchers have paid insufficient attention to the fact that effect sizes depend on the choice of the number of levels and their ranges in experiments. Moreover, the functional form of how and how much this choice affects the resultant effect size has not thus far been studied. We show that the relationship between the population effect size and number and range of levels is given as an explicit function under reasonable assumptions. Counterintuitively, it is found that researchers may affect the resultant effect size to be either double or half simply by suitably choosing the number of levels and their ranges. Through a simulation study, we confirm that this relation also applies to sample effect size indices in much the same way. Therefore, the variance-accounted-for effect size would be substantially affected by the basic research design such as the number of levels. Simple cross-study comparisons and a meta-analysis of variance-accounted-for effect sizes would generally be irrational unless differences in research designs are explicitly considered.

Recruitment and completion of research activities during regular clinical care has the potential to increase research participation in complex neurodevelopmental disorders. We evaluated the feasibility, and effect on clinical care, of conducting biomarker research within a subspecialty clinical visit for autism spectrum disorder (ASD). Children, aged 5 to 10 years, were recruited by providers in ASD clinics at 5 institutions. Biomarkers collected were growth measurements, head circumference, neurologic and dysmorphology examinations, digit ratio (2D:4D) measurement, and platelet serotonin and urinary melatonin sulfate excretion levels. Parents completed the Aberrant Behavior Checklist-Community and a medical/demographic questionnaire. Cognitive level was abstracted from the medical record. Parents and clinicians completed surveys on the effect of the study on the clinical visit. Eighty-three children and their caregivers participated. Factors limiting participation included difficulty reaching families by phone and parent concern about the study blood draw requirement. All children completed at least 4 of 7 planned research activities. Demographic factors, educational placement, and child behavior were not associated with completion of study activities. Lower nonverbal cognitive function was weakly associated with fewer activities completed. Forty-four percent of clinicians reported an effect of the research study on the clinical visit. However, neither parent-reported nor clinician-reported effect was associated with the degree of study activity completion. Recruiting study participants in the context of scheduled ASD clinical visits required significant effort. However, once recruited, participants completed most study activities, regardless of behavioral symptom severity. Research activities did not adversely affect the clinical visit.

The role of organizational context in moderating the effect of research use on pain outcomes in hospitalized children: a cross sectional study.

2017-01-23

Despite substantial research on pediatric pain assessment and management, health care professionals do not adequately incorporate this knowledge into clinical practice. Organizational context (work environment) is a significant factor in influencing outcomes; however, the nature of the mechanisms are relatively unknown. The objective of this study was to assess how organizational context moderates the effect of research use and pain outcomes in hospitalized children. A cross-sectional survey was undertaken with 779 nurses in 32 patient care units in 8 Canadian pediatric hospitals, following implementation of a multifaceted knowledge translation intervention, Evidence-based Practice for Improving Quality (EPIQ). The influence of organizational context was assessed in relation to pain process (assessment and management) and clinical (pain intensity) outcomes. Organizational context was measured using the Alberta Context Tool that includes: leadership, culture, evaluation, social capital, informal interactions, formal interactions, structural and electronic resources, and organizational slack (staff, space, and time). Marginal modeling estimated the effects of instrumental research use (direct use of research knowledge) and conceptual research use (indirect use of research knowledge) on pain outcomes while examining the effects of context. Six of the 10 organizational context factors (culture, social capital, informal interactions, resources, and organizational slack [space and time]) significantly moderated the effect of instrumental research use on pain assessment; four factors (culture, social capital, resources and organizational slack time) moderated the effect of conceptual research use and pain assessment. Only two factors (evaluation and formal interactions) moderated the effect of instrumental research use on pain management. All organizational factors except slack space significantly moderated the effect of instrumental research use on pain intensity; informal interactions and organizational slack space moderated the effect of conceptual research use and pain intensity. Many aspects of organizational context consistently moderated the effects of instrumental research use on pain assessment and pain intensity, while only a few influenced conceptual use of research on pain outcomes. Organizational context factors did not generally influence the effect of research use on pain management. Further research is required to further explore the relationships between organizational context and pain management outcomes.

Statistical significance testing is the cornerstone of quantitative research, but studies that fail to report measures of effect size are potentially missing a robust part of the analysis. We provide a rationale for why effect size measures should be included in quantitative discipline-based education research. Examples from both biological and educational research demonstrate the utility of effect size for evaluating practical significance. We also provide details about some effect size indices that are paired with common statistical significance tests used in educational research and offer general suggestions for interpreting effect size measures. Finally, we discuss some inherent limitations of effect size measures and provide further recommendations about reporting confidence intervals.

Teaching reading comprehension to learners with autism spectrum disorder: Discrepancies between teacher and research-recommended practices.

PubMed

Accardo, Amy L; Finnegan, Elizabeth G

2017-11-01

Students with autism spectrum disorder have been found to experience difficulty with reading comprehension despite intact decoding and word recognition. This identified need for targeted reading comprehension remediation results in a need for teachers to utilize research-based practices and to individualize instruction for students with autism spectrum disorder; however, teachers report a lack of access to such practices. This study utilized survey methodology to gather perceptions and experiences of teachers and to compare teacher preparedness to use effective instructional practices emerging from the extant research to teacher-reported effective practices in the classroom. Study findings, based on 112 participants, reveal a discrepancy between teacher-reported effective practices, and the practices identified as effective through research, indicating a research to practice gap. Implications for practice include professional development recommendations, and the need for increased communication between researchers and teachers.

Effect size calculation in meta-analyses of psychotherapy outcome research.

Hoyt, William T; Del Re, A C

2018-05-01

Meta-analysis of psychotherapy intervention research normally examines differences between treatment groups and some form of comparison group (e.g., wait list control; alternative treatment group). The effect of treatment is normally quantified as a standardized mean difference (SMD). We describe procedures for computing unbiased estimates of the population SMD from sample data (e.g., group Ms and SDs), and provide guidance about a number of complications that may arise related to effect size computation. These complications include (a) incomplete data in research reports; (b) use of baseline data in computing SMDs and estimating the population standard deviation (σ); (c) combining effect size data from studies using different research designs; and (d) appropriate techniques for analysis of data from studies providing multiple estimates of the effect of interest (i.e., dependent effect sizes). Clinical or Methodological Significance of this article: Meta-analysis is a set of techniques for producing valid summaries of existing research. The initial computational step for meta-analyses of research on intervention outcomes involves computing an effect size quantifying the change attributable to the intervention. We discuss common issues in the computation of effect sizes and provide recommended procedures to address them.

Effects of augmentative and alternative communication on challenging behavior: a meta-analysis.

2013-06-01

The purposes of this review were to (a) use meta-analytic procedures to examine the effectiveness of single-case AAC intervention research on challenging behaviors exhibited by individuals with disabilities, (b) identify study characteristics that moderate intervention effects, and (c) evaluate the quality of research. The authors provided inferential and descriptive analyses of 54 studies representing 111 participants and estimated effect sizes using the Nonoverlap of All Pairs (NAP) method. Overall, AAC interventions were found to be equally effective across a broad spectrum of participants and interventions. AAC interventions were more effective with younger children than with adults. Interventions in which functional behavior assessments (FBA) were used had significantly larger effect sizes than those that did not use FBAs. Further, functional communication training interventions resulted in larger effect sizes than Picture Exchange Communication System interventions. Descriptive analysis revealed that (a) interventions often occurred in atypical environments (e.g., therapy room, experimental room) and with atypical interventionists (e.g., therapists, researchers), and (b) numerous studies did not exhibit quality characteristics of single-case research.

The Comparative Outcomes Management with Electronic Data Technology (COMET) platform is extensible and designed for facilitating multicenter electronic clinical research. Our research goals were the following: (1) to conduct a comparative effectiveness trial (CET) for two obstructive sleep apnea treatments-positive airway pressure versus oral appliance therapy; and (2) to establish a new electronic network infrastructure that would support this study and other clinical research studies. The COMET platform was created to satisfy the needs of CET with a focus on creating a platform that provides comprehensive toolsets, multisite collaboration, and end-to-end data management.

Introduction: The Comparative Outcomes Management with Electronic Data Technology (COMET) platform is extensible and designed for facilitating multicenter electronic clinical research. Background: Our research goals were the following: (1) to conduct a comparative effectiveness trial (CET) for two obstructive sleep apnea treatments—positive airway pressure versus oral appliance therapy; and (2) to establish a new electronic network infrastructure that would support this study and other clinical research studies. Discussion: The COMET platform was created to satisfy the needs of CET with a focus on creating a platform that provides comprehensive toolsets, multisite collaboration, and end-to-end data management. The platform also provides medical researchers the ability to visualize and interpret data using business intelligence (BI) tools. Conclusion: COMET is a research platform that is scalable and extensible, and which, in a future version, can accommodate big data sets and enable efficient and effective research across multiple studies and medical specialties. The COMET platform components were designed for an eventual move to a cloud computing infrastructure that enhances sustainability, overall cost effectiveness, and return on investment. PMID:25848590

Meta-Analysis With Complex Research Designs: Dealing With Dependence From Multiple Measures and Multiple Group Comparisons

PubMed Central

Scammacca, Nancy; Roberts, Greg; Stuebing, Karla K.

2013-01-01

Previous research has shown that treating dependent effect sizes as independent inflates the variance of the mean effect size and introduces bias by giving studies with more effect sizes more weight in the meta-analysis. This article summarizes the different approaches to handling dependence that have been advocated by methodologists, some of which are more feasible to implement with education research studies than others. A case study using effect sizes from a recent meta-analysis of reading interventions is presented to compare the results obtained from different approaches to dealing with dependence. Overall, mean effect sizes and variance estimates were found to be similar, but estimates of indexes of heterogeneity varied. Meta-analysts are advised to explore the effect of the method of handling dependence on the heterogeneity estimates before conducting moderator analyses and to choose the approach to dependence that is best suited to their research question and their data set.

Recognizing a need for rigorous, experimental research to support the efforts of workplaces and policymakers in improving the health and wellbeing of employees and their families, the National Institutes of Health and the Centers for Disease Control and Prevention formed the Work, Family & Health Network (WFHN). The WFHN is implementing an innovative multisite study with a rigorous experimental design (adaptive randomization, control groups), comprehensive multilevel measures, a novel and theoretically based intervention targeting the psychosocial work environment, and translational activities. This paper describes challenges and benefits of designing a multilevel and transdisciplinary research network that includes an effectiveness study to assess intervention effects on employees, families, and managers; a daily diary study to examine effects on family functioning and daily stress; a process study to understand intervention implementation; and translational research to understand and inform diffusion of innovation. Challenges were both conceptual and logistical, spanning all aspects of study design and implementation. In dealing with these challenges, however, the WFHN developed innovative, transdisciplinary, multi-method approaches to conducting workplace research that will benefit both the research and business communities.

Concern about food security and its effect on persistent undernutrition has increased interest in how agriculture could be used to improve nutritional outcomes in developing countries. Yet the evidence base for the impact of agricultural interventions targeted at improved nutrition is currently poor. To map the extent and nature of current and planned research on agriculture for improved nutrition in order to identify gaps where more research might be useful. The research, which was conducted from April to August 2012, involved developing a conceptual framework linking agriculture and nutrition, identifying relevant research projects and programs, devising and populating a "template" with details of the research projects in relation to the conceptual framework, classifying the projects, and conducting a gap analysis. The study identified a large number of research projects covering a broad range of themes and topics. There was a strong geographic focus on sub-Saharan Africa, and many studies were explicitly concerned with nutritional impacts on women and children. Although the study revealed a diverse and growing body of research, it also identified research gaps. Few projects consider the entire evidence chain linking agricultural input or practice to nutritional outcomes. There is comparatively little current research on indirect effects of agriculture on nutrition, or the effect of policies or governance, rather than technical interventions. Most research is focused on undernutrition and small farmer households, and few studies target consumers generally, urban populations, or nutrition-related non-communicable diseases. There is very little work on the cost-effectiveness of agricultural interventions. On the basis of these findings, we make suggestions for research investment and for broader engagement of researchers and disciplines in developing approaches to design and evaluate agricultural programs for improved nutrition.

Objective To examine the effectiveness of current community-based participatory research (CBPR) clinical trials involving racial and ethnic minorities. Data Source All published peer-reviewed CBPR intervention articles in PubMed and CINAHL databases from January 2003 to May 2010. Study Design We performed a systematic literature review. Data Collection/Extraction Methods Data were extracted on each study's characteristics, community involvement in research, subject recruitment and retention, and intervention effects. Principle Findings We found 19 articles meeting inclusion criteria. Of these, 14 were published from 2007 to 2010. Articles described some measures of community participation in research with great variability. Although CBPR trials examined a wide range of behavioral and clinical outcomes, such trials had very high success rates in recruiting and retaining minority participants and achieving significant intervention effects. Conclusions Significant publication gaps remain between CBPR and other interventional research methods. CBPR may be effective in increasing participation of racial and ethnic minority subjects in research and may be a powerful tool in testing the generalizability of effective interventions among these populations. CBPR holds promise as an approach that may contribute greatly to the study of health care delivery to disadvantaged populations. PMID:22353031

A critical mass of public health practitioners with expertise in analytic techniques and best practices in comparative effectiveness research is needed to fuel informed decisions and improve the quality of health care. The purpose of this case study is to describe the development and formative evaluation of a technology-enhanced comparative effectiveness research learning curriculum and to assess its potential utility to improve core comparative effectiveness research competencies among the public health workforce. Selected public health experts formed a multidisciplinary research collaborative and participated in the development and evaluation of a blended 15-week comprehensive e-comparative effectiveness research training program, which incorporated an array of health informatics technologies. Results indicate that research-based organizations can use a systematic, flexible, and rapid means of instructing their workforce using technology-enhanced authoring tools, learning management systems, survey research software, online communities of practice, and mobile communication for effective and creative comparative effectiveness research training of the public health workforce.

The effects of Web site structure: the role of personal difference.

PubMed

Chung, Hwiman; Ahn, Euijin

2007-12-01

This study examined the effects of Web site structures in terms of advertising effectiveness- memory, attitude, and behavioral intentions. The primary research question for this study is, What type of Web site (Web ad) structure is most effective? In the pilot study, we tested the difference between two Web site structures, linear and interactive, in terms of traditional advertising effectiveness. Results from the pilot study did not support our research expectations. However, differences in terms of memory were noted between the two structures. After re-creating the Web site based on subjects' comments, in the final experiment, we examined the differences between the two structures and the moderating role of personality difference on the effects of Web site structure. The results confirm that participants' attitude, memory, and behavioral intentions were affected differently by the different Web site structures. However, some research hypotheses were not supported by the current data.

Genes, Environments, and Sex Differences in Alcohol Research.

Salvatore, Jessica E; Cho, Seung Bin; Dick, Danielle M

2017-07-01

The study of sex differences has been identified as one way to enhance scientific reproducibility, and the National Institutes of Health (NIH) have implemented a new policy to encourage the explicit examination of sex differences. Our goal here is to address sex differences in behavioral genetic research on alcohol outcomes. We review sex differences for alcohol outcomes and whether the source and magnitude of genetic influences on alcohol consumption and alcohol use disorder (AUD) are the same across sexes; describe common research designs for studying sex-specific gene-by-environment interaction (G × E) effects; and discuss the role of statistical power and theory when testing sex-specific genetic effects. There are robust sex differences for many alcohol outcomes. The weight of evidence suggests that the source and magnitude of genetic influences on alcohol consumption and AUD are the same across sexes. Whether there are sex-specific G × E effects has received less attention to date. The new NIH policy necessitates a systematic approach for studying sex-specific genetic effects in alcohol research. Researchers are encouraged to report power for tests of these effects and to use theory to develop testable hypotheses, especially for studies of G × E.

Researchers’ Intuitions About Power in Psychological Research

Bakker, Marjan; Hartgerink, Chris H. J.; Wicherts, Jelte M.; van der Maas, Han L. J.

2016-01-01

Many psychology studies are statistically underpowered. In part, this may be because many researchers rely on intuition, rules of thumb, and prior practice (along with practical considerations) to determine the number of subjects to test. In Study 1, we surveyed 291 published research psychologists and found large discrepancies between their reports of their preferred amount of power and the actual power of their studies (calculated from their reported typical cell size, typical effect size, and acceptable alpha). Furthermore, in Study 2, 89% of the 214 respondents overestimated the power of specific research designs with a small expected effect size, and 95% underestimated the sample size needed to obtain .80 power for detecting a small effect. Neither researchers’ experience nor their knowledge predicted the bias in their self-reported power intuitions. Because many respondents reported that they based their sample sizes on rules of thumb or common practice in the field, we recommend that researchers conduct and report formal power analyses for their studies.

2015-01-01

Outdoor air pollution is a global problem with serious effects on human health, and children are considered to be highly susceptible to the effects of air pollution. To conduct a comprehensive and updated systematic review of the literature reporting the effects of outdoor air pollution on the respiratory health of children in Canada. Searches of four electronic databases between January 2004 and November 2014 were conducted to identify epidemiological studies evaluating the effect of exposure to outdoor air pollutants on respiratory symptoms, lung function measurements and the use of health services due to respiratory conditions in Canadian children. The selection process and quality assessment, using the Newcastle-Ottawa Scale, were conducted independently by two reviewers. Twenty-seven studies that were heterogeneous with regard to study design, population, respiratory outcome and air pollution exposure were identified. Overall, the included studies reported adverse effects of outdoor air pollution at concentrations that were below Canadian and United States standards. Heterogeneous effects of air pollutants were reported according to city, sex, socioeconomic status and seasonality. The present review also describes trends in research related to the effect of air pollution on Canadian children over the past 25 years. The present study reconfirms the adverse effects of outdoor air pollution on the respiratory health of children in Canada. It will help researchers, clinicians and environmental health authorities identify the available evidence of the adverse effect of outdoor air pollution, research gaps and the limitations for further research.

Comparative effectiveness research for the clinician researcher: a framework for making a methodological design choice.

PubMed

Williams, Cylie M; Skinner, Elizabeth H; James, Alicia M; Cook, Jill L; McPhail, Steven M; Haines, Terry P

2016-08-17

Comparative effectiveness research compares two active forms of treatment or usual care in comparison with usual care with an additional intervention element. These types of study are commonly conducted following a placebo or no active treatment trial. Research designs with a placebo or non-active treatment arm can be challenging for the clinician researcher when conducted within the healthcare environment with patients attending for treatment.A framework for conducting comparative effectiveness research is needed, particularly for interventions for which there are no strong regulatory requirements that must be met prior to their introduction into usual care. We argue for a broader use of comparative effectiveness research to achieve translatable real-world clinical research. These types of research design also affect the rapid uptake of evidence-based clinical practice within the healthcare setting.This framework includes questions to guide the clinician researcher into the most appropriate trial design to measure treatment effect. These questions include consideration given to current treatment provision during usual care, known treatment effectiveness, side effects of treatments, economic impact, and the setting in which the research is being undertaken.

Assessing the Expected Value of Research Studies in Reducing Uncertainty and Improving Implementation Dynamics.

PubMed

Grimm, Sabine E; Dixon, Simon; Stevens, John W

2017-07-01

With low implementation of cost-effective health technologies being a problem in many health systems, it is worth considering the potential effects of research on implementation at the time of health technology assessment. Meaningful and realistic implementation estimates must be of dynamic nature. To extend existing methods for assessing the value of research studies in terms of both reduction of uncertainty and improvement in implementation by considering diffusion based on expert beliefs with and without further research conditional on the strength of evidence. We use expected value of sample information and expected value of specific implementation measure concepts accounting for the effects of specific research studies on implementation and the reduction of uncertainty. Diffusion theory and elicitation of expert beliefs about the shape of diffusion curves inform implementation dynamics. We illustrate use of the resulting dynamic expected value of research in a preterm birth screening technology and results are compared with those from a static analysis. Allowing for diffusion based on expert beliefs had a significant impact on the expected value of research in the case study, suggesting that mistakes are made where static implementation levels are assumed. Incorporating the effects of research on implementation resulted in an increase in the expected value of research compared to the expected value of sample information alone. Assessing the expected value of research in reducing uncertainty and improving implementation dynamics has the potential to complement currently used analyses in health technology assessments, especially in recommendations for further research. The combination of expected value of research, diffusion theory, and elicitation described in this article is an important addition to the existing methods of health technology assessment.

When Trust Is Not Enough: A Serial Mediation Model Explaining the Effect of Race Identity, eHealth Information Efficacy, and Information Behavior on Intention to Participate in Clinical Research.

PubMed

Strekalova, Yulia A

2018-02-01

Black participants remain significantly underrepresented in clinical research. Mistrust in medical researchers has been named a key barrier to the successful enrollment of minority study participants. However, trust is a social-interactional construct, and its effects on behavior are complex. This study hypothesized that intention to participate in clinical research is mediated by trust in medical researchers, eHealth literacy, and information seeking behavior. The data were collected through an online survey ( N = 340) and analyzed to identify serial mediation. The model showed insignificant direct effect of race identity on behavioral intention, c' = -0.19, t(335) = -1.22, p = .22, but a significant total effect, c = -0.44, t(335) = -2.59, p < .01. The indirect effect of race identity on behavioral intention was also significant. The positive effect of trust in medical researchers on decisions to participate in clinical research can be amplified by stronger eHealth literacy and active information seeking, which can be supported through focused strategic health education and communication interventions. A focus on the development of information literacy that could provide prospective minority research volunteers with skills for informed decision making should be explored as an option for increasing mindful, informed participation in clinical research among currently underrepresented racial and ethnic groups.

Focusing on appraisals: how and why anger and fear influence driving risk perception.

PubMed

Lu, Jingyi; Xie, Xiaofei; Zhang, Ruogu

2013-06-01

The present research explores how and why anger and fear influence driving risk perception. Based on appraisal tendency framework, researchers hypothesized that anger and fear would influence driving risk perception in opposite directions due to their differences in appraisals. Study 1 showed that anger reduced risk perception, whereas fear increased it. In Studies 2, 3, and 4, the researchers adopted the paradigm of reappraisal to investigate the causes of the opposite effects found in Study 1. Consistent with our hypothesis, appraisals accounted for these effects: After reappraisals along the dimensions of certainty (Study 2), control (Study 3), and responsibility (Study 4), the different effects between anger and fear on driving risk perception diminished or disappeared. In addition, fearful or angry experience mediated the effects of reappraisals on driving risk perception. The findings highlight the necessity to differentiate anger and fear in road safety management. Additionally, the current research also provides feasible methods (e.g., certainty, control, or responsibility reappraisal) to intervene in driving risk perception, which is important for driving safety.

Project Lead the Ways' Long-Term Effects on Post-Secondary Engineering Academic Success

NASA Astrophysics Data System (ADS)

Zion, George H.

The purpose of this study was to investigate the relationship between students' high school Project Lead They Way participation and their subsequent academic success in post-secondary engineering studies and to assess to what degree, if any, their level of Project Lead The Way (PLTW) participation, gender, and AALANA status (African American, Latino/a American and Native American) effected this success. PLTW is the nation's single largest provider of pre-engineering curriculums, the subject of this research study, currently being offered in over 3,200 secondary schools nationwide. Despite this level of integration, the amount of research on PLTW's effectiveness has been very limited. To date, the majority of the literature on PLTW has examined its impact on students' high school academic performance or their desire to further their engineering studies. The findings from these studies have been overwhelmingly positive, indicating that PLTW students often had greater achievements in math and science and either plan to, or have actually enrolled, in post-secondary studies at higher rates. Nevertheless, the amount of literature on PLTW's effects on students' academic success in post-secondary engineering studies is very limited. Furthermore, no research has yet to examine for the moderating effects of gender, ethnicity, or level of PLTW participation on students' post-secondary academics success. The population of interest for this research study was 1,478 students who entered an undergraduate engineering program from 2007 to 2009 at a privately endowed, co-educational university located in the northeastern United States. The findings of this research study were that virtually all the effects of PLTW participation, gender, and AALANA status had on academic success were observed during students' freshmen and sophomore years. These effects were positive for PLTW participation, and adverse for female and AALANA students. Additionally, PLTW participation, gender, and AALANA status only explained a small amount of the variance for each of the academic success metrics. These conclusions suggest that future research on PLTW should focus on the first and second year of study and expand the factors examined, both quantitative and qualitative, to gain a greater understanding of the complex factors that influence students' initial academic success in post-secondary engineering studies.

Defining Research: The Effect of Linguistic Choices on the Intentions to Participate in Clinical Research.

PubMed

Strekalova, Yulia A

2017-06-01

Significant barriers to participant recruitment for clinical research (CR) are related to effective communication, and nurse coordinators are entrusted with being knowledge brokers between investigators and prospective participants. This prospective cohort study sought to identify linguistic choices that could inform and facilitate recruitment efforts. Healthy adults ( N = 204) were invited to join an online survey to assess the likelihood of participation in CR based on short and extended definitions of CR. Five short definitions included clinical trial, clinical study, health-related research study, community participatory study, and quality improvement study. The likelihood of participation in CR was the lowest for clinical trial and the highest for health-related research study. However, when only an extended definition was provided, those differences were not observed. A linguistic change from trial to study could lead to positive attitude toward CR and improvements in recruitment. However, ethical implications of linguistic choices should be considered.

The incorporation of team context into research and practice regarding team effectiveness in NGOs projects is a constant challenge. The research seeks to address the gap and identify the critical determinants of team effectiveness in projects undertaken by non-governmental organizations. Using a systematic process, the study involved both literature and focus group discussions to generate the required items. A total of 157 respondents (Team Members and Team Leaders) were part of the study that filled the questionnaires. Using exploratory factor analysis followed by confirmatory factor analysis, both convergent and discriminant validity was established. The present study found that team effectiveness in NGO social projects has a total of seven dimensions namely: Inter team coordination, community social linkage, team performance, knowledge, skills, and attitudes, leadership communication and engagement, decision making and information sharing, and team formation. There is a significant lack of research on team effectiveness in NGO projects. Where considerably large proportion of research on team effectiveness has focused on the corporate sector, the non-governmental teams have been neglected. This study clearly highlights the determinants that make up team effectiveness in NGOs. The determinants identified will help to specifically look at the effectiveness of teams in NGO projects. The study would help NGOs identify the dimensions in which they may be performing in a weaker manner and direct their energies in improving the factors. Copyright © 2017 Elsevier Ltd.

Behavioral Recommendations in Health Research News as Cues to Action: Self-Relevancy and Self-Efficacy Processes.

PubMed

Chang, Chingching

2016-08-01

This study argues that behavioral recommendations in health news function as cues to action. A proposed self-oriented model seeks to explore the impacts of behavioral recommendations in health research news as cues to action through their influences on self-relevancy and self-efficacy. A content analysis (Study 1) first establishes that health research news commonly features behavioral recommendations. A message experiment (Study 2) then explores the utility of behavioral recommendations as cues to action by demonstrating a self-relevancy effect: Health research news with, as opposed to without, behavioral recommendations increases the self-relevancy of advocated health behaviors, which then improve people's attitudes toward and intentions to adopt those behaviors. A second message experiment (Study 3) tests whether varying presentations of behavioral recommendations alter their effectiveness as cues to action and thus people's behavioral intentions through a dual effect process. In addition to the previously demonstrated self-relevancy effect, this experiment shows that concrete, as opposed to abstract, behavioral recommendations trigger a self-efficacy effect, increasing perceived self-efficacy and further improving behavioral intentions.

Objective Randomized controlled trials remain the gold standard for evaluating cancer intervention efficacy. Randomized trials are not always feasible, practical, or timely, and often don’t adequately reflect patient heterogeneity and real-world clinical practice. Comparative effectiveness research can leverage secondary data to help fill knowledge gaps randomized trials leave unaddressed; however, comparative effectiveness research also faces shortcomings. The goal of this project was to develop a new model and inform an evolving framework articulating cancer comparative effectiveness research data needs. Study Design and Setting We examined prevalent models and conducted semi-structured discussions with 76 clinicians and comparative effectiveness research researchers affiliated with the Agency for Healthcare Research and Quality’s cancer comparative effectiveness research programs. Results A new model was iteratively developed, and presents cancer comparative effectiveness research and important measures in a patient-centered, longitudinal chronic care model better-reflecting contemporary cancer care in the context of the cancer care continuum, rather than a single-episode, acute-care perspective. Conclusion Immediately relevant for federally-funded comparative effectiveness research programs, the model informs an evolving framework articulating cancer comparative effectiveness research data needs, including evolutionary enhancements to registries and epidemiologic research data systems. We discuss elements of contemporary clinical practice, methodology improvements, and related needs affecting comparative effectiveness research’s ability to yield findings clinicians, policymakers, and stakeholders can confidently act on.

Multidisciplinary analysis and design is inherently a team activity due to the variety of required expertise and knowledge. As a team activity, multidisciplinary research cannot escape the issues that affect all teams. The level of technical diversity required to perform multidisciplinary analysis and design makes the teaming aspects even more important. A study was conducted at the NASA Langley Research Center to develop a model of multidiscipline teams that can be used to help understand their dynamics and identify key factors that influence their effectiveness. The study sought to apply the elements of systems thinking to better understand the factors, both generic and Langley-specific, that influence the effectiveness of multidiscipline teams. The model of multidiscipline research teams developed during this study has been valuable in identifying means to enhance team effectiveness, recognize and avoid problem behaviors, and provide guidance for forming and coordinating multidiscipline teams.

Women and people of color continue to be underrepresented among biomedical researchers to an alarming degree. Research interest and subsequent productivity have been shown to be affected by the research training environment through the mediating effects of research self-efficacy. This article presents the findings of a study to determine whether a short-term research training program coupled with an efficacy enhancing intervention for novice female biomedical scientists of diverse racial backgrounds would increase their research self-efficacy beliefs. Forty-three female biomedical scientists were randomized into a control or intervention group and 15 men participated as a control group. Research self-efficacy significantly increased for women who participated in the self-efficacy intervention workshop. Research self-efficacy within each group also significantly increased following the short-term research training program, but cross-group comparisons were not significant. These findings suggest that educational interventions that target sources of self-efficacy and provide domain-specific learning experiences are effective at increasing research self-efficacy for women and men. Further studies are needed to determine the longitudinal outcomes of this effort.

The effects of HIV and aging on brain functions: proposing a research framework and update on last 3 years' findings.

PubMed

Cysique, Lucette A; Brew, Bruce J

2014-07-01

The effect of HIV and aging on brain functions is an increasingly important topic of research: HIV-infected (HIV+) persons aged ≥50 represent a growing part of the HIV epidemic. Research is embracing this new axis, but there has been a lack of conceptualization of the factors that are at stake in both aging and HIV. To start to remedy this theoretical limitation, we are proposing a research framework in the hope that it will optimize how research questions and findings are formulated. Moreover, in the light of this proposed research framework, we review the last 3  years' research findings. Our review highlights that as HIV+ persons are aging, there is some signal for acceleration of normal aging processes and facilitated expression of age-associated diseases. Evidence for dramatic neurodegeneration in aging HIV+ persons remains limited and may be different in nature to typical neurodegenerative processes. Also, it should be kept in mind that most HIV+ persons are still below age 60. The vast majority of studies are still cross-sectional thereby underlining the critical importance of longitudinal studies to fully assess the effect of comorbidities. The complex effects of aging and nonaging comorbidities and key HIV effects (as opposed to only HIV status) need to be taken into account in future research by increasing sample size and selecting the most appropriate control group(s). Ideally, life-span studies should be established using neuropsychological and neuroimaging outcomes that have a proven track record in both HIV-related brain injury and brain aging. These would be similar to those that exist in non-HIV aging research and would optimally account for comorbidity effects and survivor bias.

2014-10-01

The impact of evidence-based medicine and clinical epidemiology on clinical research has contributed to the development of Chinese medicine in modern times over the past two decades. Many concepts and methods of modern science and technology are emerging in Chinese medicine research, resulting in constant progress. Systematic reviews, randomized controlled trials and other advanced mathematic approaches and statistical analysis methods have brought reform to Chinese medicine. In this new era, Chinese medicine researchers have many opportunities and challenges. On the one hand, Chinese medicine researchers need to dedicate themselves to providing enough evidence to the world through rigorous studies, whilst on the other hand, they also need to keep up with the speed of modern medicine research. For example, recently, real world study, comparative effectiveness research, propensity score techniques and registry study have emerged. This article aims to inspire Chinese medicine researchers to explore new areas by introducing these new ideas and new techniques.

Between 2009 and 2012, eight operational research capacity building courses were completed in Paris (3), Luxembourg (1), India (1), Nepal (1), Kenya (1) and Fiji (1). Courses had strict milestones that were subsequently adopted by the Structured Operational Research and Training InitiaTive (SORT IT) of the World Health Organization. We report on the numbers of enrolled participants who successfully completed courses, the number of papers published and their reported effect on policy and/or practice. Retrospective cohort study including a survey. Participant selection criteria ensured that only those proposing specific programme-related and relevant operational research questions were selected. Effects on policy and/or practice were assessed in a standardised manner by two independent reviewers. Of 93 enrolled participants from 31 countries (14 in Africa, 13 in Asia, two in Latin America and two in South Pacific), 83 (89%) completed their courses. A total of 96 papers were submitted to scientific journals of which 89 (93%) were published and 88 assessed for effect on policy and practice. There was a reported effect in 65 (74%) studies including changes to programme implementation (27), adaptation of monitoring tools (24) and changes to existing guidelines (20). Three quarters of published operational research studies from these structured courses had reported effects on policy and/or practice. It is important that this type of tracking becomes a standard component of operational research and research in general. © 2014 John Wiley & Sons Ltd.

The purpose of the study was to investigate the effects of research-article writing motivation and use of self-regulatory writing strategies in explaining second language (L2) research-article abstract writing ability, alongside the L2 literacy effect. Four measures were administered: a L2 literacy test, a research abstract performance assessment, and inventories of writing motivation and strategy. Participants were L2 graduate students in Taiwan (N=185; M age=25.8 yr., SD=4.5, range=22-53). Results of structural equation modeling showed a direct effect of motivation on research-article writing ability, but no direct effect of strategy or indirect effect of motivation via strategy on research-article writing ability, with L2 literacy controlled. The findings suggest research-article writing instruction should address writing motivation, besides L2 literacy.

The United States aspires to use information from comparative effectiveness research (CER) to reduce waste and contain costs without instituting a formal rationing mechanism or compromising patient or physician autonomy with regard to treatment choices. With such ambitious goals, traditional combinations of research designs and analytical methods used in CER may lead to disappointing results. In this paper, I study how alternate regimes of comparative effectiveness information help shape the marginal benefits (demand) curve in the population and how such perceived demand curves impact decision-making at the individual patient level and welfare at the societal level. I highlight the need to individualize comparative effectiveness research in order to generate the true (normative) demand curve for treatments. I discuss methodological principles that guide research designs for such studies. Using an example of the comparative effect of substance abuse treatments on crime, I use novel econometric methods to salvage individualized information from an existing dataset. PMID:21601299

Avian research that involves potential disturbance to the study species may have unintended fitness consequences and could lead to biases in measurements of interest. The effects of band resighting on the behavior of mixed-species flocks of staging waterbirds were evaluated against recreational pedestrian activity that was expected to cause flushing. We found a model with additive effects of distance (near, 0-50 m, or far, 50-200 m) and disturbance type (researcher or pedestrian) best explained flock behaviors. The proportion of staging flocks that flushed in response to pedestrians was greatest when pedestrians were within 50 m of the flock. Virtually no flushes were observed in response to researchers, regardless of distance. These results could assist in alleviating concerns that accepted protocols used for intensive band resighting studies on staging seabirds of special conservation status, such as Roseate (Sterna dougallii) and Common (S. hirundo) terns, may have adverse effects. Our framework could be used by others to test the effects of similar research on sensitive species.

Baccalaureate nursing students perceive research as unattractive, doubt the value of nursing research, and do not appreciate the link of research with practice. No studies have examined students' cognitive load during an evidence-based practice research course versus a traditional research course. To assess the effect of integrating constructivist theories and evidence-based practice on student cognitive load and learning performance in a research course. A true experimental study. A Registered Nurse-to-Bachelor of Science in Nursing program. Six classes of second-year students. Students were randomly allocated to the control group (two classes) or the experimental group (two classes) using cluster randomization. The control group underwent "traditional research"; the experimental group experienced "integrating evidence-based practice into research." Instruments for outcome assessment include the Cognitive Load Scale, cognitive test, team critique paper, and qualitative feedback on course satisfaction. The between-subjects effects were compared by Analysis of Covariance. The experimental group had significantly higher mental load (8.74 vs. 7.27, p<.001), mental effort (11.07 vs. 10.07, p=.009), mental efficiency (0.33 vs. -0.31, p<.001), and research knowledge (70.61 vs. 44.92, p<.001) than the control group. The experimental group had better critique paper scores in introduction (92.80%), literature review (91.70%), and assignment requirement and writing (89.40%). Some experimental learners expressed satisfaction with learning evidence-based practice (17.78%) and critiquing a research article (7.78%). Integrating evidence-based practice into a research course not only improved the research knowledge of baccalaureate nursing students, but also increased their mental load, mental effort, and mental efficiency. Additional studies may track learners' responses to different learning systems using the developed instrument to measure the three types of cognitive load. These findings may help educators design more effective and interesting curricula for integrating research and evidence-based practice into the studies of student nurses. Copyright © 2016.

Assessing acute effects of trapping, handling, and tagging on the behavior of wildlife using GPS telemetry: a case study of the common brushtail possum.

PubMed

Dennis, Todd E; Shah, Shabana F

2012-01-01

Trapping, handling, and deployment of tracking devices (tagging) are essential aspects of many research and conservation studies of wildlife. However, often these activities place nonhuman animals under considerable physical or psychological distress, which disrupts normal patterns of behavior and may ultimately result in deleterious effects on animal welfare and the validity of research results. Thus, knowledge of how trapping, handling, and tagging alter the behavior of research animals is essential if measures to ameliorate stress-related effects are to be developed and implemented. This article describes how time-stamped location data obtained by global-positioning-system telemetry can be used to retrospectively characterize acute behavioral responses to trapping, handling, and tagging in free-ranging animals used for research. Methods are demonstrated in a case study of the common brushtail possum, a semiarboreal phalangerid marsupial native to Australia. The study discusses possible physiological causes of observed effects and offers general suggestions regarding simple means to reduce trapping-handling-and-tagging-related stress in field studies of vertebrates.

Many individuals with autism cannot speak or cannot speak intelligibly. A variety of aided augmentative and alternative communication (AAC) approaches have been investigated. Most of the research on these approaches has been single-case research, with small numbers of participants. The purpose of this investigation was to meta-analyze the single case research on the use of aided AAC with individuals with autism spectrum disorders (ASD). Twenty-four single-case studies were analyzed via an effect size measure, the Improvement Rate Difference (IRD). Three research questions were investigated concerning the overall impact of AAC interventions on targeted behavioral outcomes, effects of AAC interventions on individual targeted behavioral outcomes, and effects of three types of AAC interventions. Results indicated that, overall, aided AAC interventions had large effects on targeted behavioral outcomes in individuals with ASD. AAC interventions had positive effects on all of the targeted behavioral outcome; however, effects were greater for communication skills than other categories of skills. Effects of the Picture Exchange Communication System and speech-generating devices were larger than those for other picture-based systems, though picture-based systems did have small effects.

The effects of religiosity on psychopathology in emerging adults: intrinsic versus extrinsic religiosity.

2014-10-01

Recent research has suggested that religion may play an important role in determining mental health. Although research has examined the effects of religiosity on specific types of psychopathology, less research has examined psychopathology broadly in the context of particular aspects of religion. Thus, the current study examined intrinsic and extrinsic religiosity and a range of psychopathology in 486 emerging adult college students. Results of a MANOVA indicated a main effect for intrinsic religiosity on a range of psychopathology and an interaction effect between intrinsic and extrinsic religiosity on antisocial personality problems. Implications and limitations of the current study are discussed.

Critical success factors in implementing an e-rostering system in a healthcare organisation.

2017-01-01

Effective and efficient staff scheduling has always been a challenging issue, especially in health service organisations. Both the extremes of staff shortage and overage have an adverse impact on the performance of healthcare organisations. In this case, an electronic and systematic staff scheduling (e-rostering) system is the often seen as the best solution. Unless an organisation has an effective implementation of such a system, possible cost savings, efficiency, and benefits could be minimal. This study is aimed to research key success factors for the successful effective implementation of an electronic rostering system, especially at healthcare organisations. A case study research method was used to evaluate critical success factors for effectively implementing an e-rostering system. The data were collected through interviews and observations. The findings indicate that technical support, an effective policy, leadership, clear goals and objectives, gradual change, evidence of the advantages of the new system, senior management support, and effective communication are the critical success factors in implementing an e-rostering system in healthcare organisations. Prior to this study, no such factors were grounded in the current context, so this research would help in bridging the gap towards effective implementation of an e-rostering system in the healthcare sector. This research also suggests future studies in different cultures and contexts.

Few studies have been conducted on the rationales for using interpretive guidelines for effect size, and most of the previous statistical power surveys have covered broad research domains. The present study aimed to estimate the statistical power and to obtain realistic target effect sizes of depression research in Japan. We systematically reviewed 18 leading journals of psychiatry and psychology in Japan and identified 974 depression studies that were mentioned in 935 articles published between 1990 and 2006. In 392 studies, logistic regression analyses revealed that using clinical populations was independently associated with being a statistical power of <0.80 (odds ratio 5.9, 95% confidence interval 2.9-12.0) and of <0.50 (odds ratio 4.9, 95% confidence interval 2.3-10.5). Of the studies using clinical populations, 80% did not achieve a power of 0.80 or more, and 44% did not achieve a power of 0.50 or more to detect the medium population effect sizes. A predictive model for the proportion of variance explained was developed using a linear mixed-effects model. The model was then used to obtain realistic target effect sizes in defined study characteristics. In the face of a real difference or correlation in population, many depression researchers are less likely to give a valid result than simply tossing a coin. It is important to educate depression researchers in order to enable them to conduct an a priori power analysis. © 2011 The Authors.

Olsson, Tina M; Sundell, Knut

2016-05-01

The core of evidence-based practice (EBP) as advocated for within the practice arms of the health and social sciences is to promote the routine incorporation of the best available research evidence into practice efforts. This requires discipline-specific education that is not only grounded in professional practice but also prepares would-be scientists in the application of the sophisticated techniques that characterize today's high research standards. Doctoral-level education is an important primer for future scientific endeavors across disciplines. This study examined 2334 theses published across Sweden in public health, criminology, nursing, psychiatry, psychology, social work, and sociology during the period 1997-2012. Of the theses reviewed, 13% aimed to investigate the effects of interventions. The highest percentage of effectiveness studies was found in nursing, public health, and psychology. The percentage of outcome research increased during the period. Controlled studies (with comparison group and pre- and post-test) occurred primarily within public health, nursing, psychiatry, and psychology. Of the 296 theses that included an intervention effectiveness study, 131 (44%), or 5.6% of all theses reviewed, met all four assessment criteria for quality. PhD education across seven disciplines in Sweden may be producing a professional core of scientists that is ill prepared to produce the type of research that is necessary to inform practice of the effects of its interventions as exposure to the rigors of quality effectiveness research is all but non-existent. This has implications for the advancement of an evidence-based practice and intervention science more broadly.

Can research assessments themselves cause bias in behaviour change trials? A systematic review of evidence from solomon 4-group studies.

2011-01-01

The possible effects of research assessments on participant behaviour have attracted research interest, especially in studies with behavioural interventions and/or outcomes. Assessments may introduce bias in randomised controlled trials by altering receptivity to intervention in experimental groups and differentially impacting on the behaviour of control groups. In a Solomon 4-group design, participants are randomly allocated to one of four arms: (1) assessed experimental group; (2) unassessed experimental group (3) assessed control group; or (4) unassessed control group. This design provides a test of the internal validity of effect sizes obtained in conventional two-group trials by controlling for the effects of baseline assessment, and assessing interactions between the intervention and baseline assessment. The aim of this systematic review is to evaluate evidence from Solomon 4-group studies with behavioural outcomes that baseline research assessments themselves can introduce bias into trials. Electronic databases were searched, supplemented by citation searching. Studies were eligible if they reported appropriately analysed results in peer-reviewed journals and used Solomon 4-group designs in non-laboratory settings with behavioural outcome measures and sample sizes of 20 per group or greater. Ten studies from a range of applied areas were included. There was inconsistent evidence of main effects of assessment, sparse evidence of interactions with behavioural interventions, and a lack of convincing data in relation to the research question for this review. There were too few high quality completed studies to infer conclusively that biases stemming from baseline research assessments do or do not exist. There is, therefore a need for new rigorous Solomon 4-group studies that are purposively designed to evaluate the potential for research assessments to cause bias in behaviour change trials.

2015-01-01

Research is being carried out to develop and test new potentially more effective tuberculosis vaccines. Among the vaccines being developed are those that target adolescents. This study explored the stakeholders' perceptions about adolescent participation in a hypothetical tuberculosis vaccine trial in Ugandan adolescents. Focus group discussions with adolescents, parents of infants and adolescents, and key informant interviews with community leaders and traditional healers were conducted. The majority of the respondents expressed potential willingness to allow their children participate in a tuberculosis vaccine trial. Main motivations for potential participation would be being able to learn about health-related issues. Hesitations included the notion that trial participation would distract the youths from their studies, fear of possible side effects of an investigational product, and potential for being sexually exploited by researchers. In addition, bad experiences from participation in previous research and doubts about the importance of research were mentioned. Suggested ways to motivate participation included: improved clarity on study purpose, risks, benefits and better scheduling of study procedures to minimize disruption to participants' academic schedules. Findings from this study suggest that the community is open to potential participation of adolescents in a tuberculosis vaccine trial. However, there is a need to communicate more effectively with the community about the purpose of the trial and its effects, including safety data, in a low-literacy, readily understood format. This raises a challenge to researchers, who cannot know all the potential effects of a trial product before it is tested.

Pre-study feasibility and identifying sensitivity analyses for protocol pre-specification in comparative effectiveness research.

2014-05-01

The use of healthcare databases for comparative effectiveness research (CER) is increasing exponentially despite its challenges. Researchers must understand their data source and whether outcomes, exposures and confounding factors are captured sufficiently to address the research question. They must also assess whether bias and confounding can be adequately minimized. Many study design characteristics may impact on the results; however, minimal if any sensitivity analyses are typically conducted, and those performed are post hoc. We propose pre-study steps for CER feasibility assessment and to identify sensitivity analyses that might be most important to pre-specify to help ensure that CER produces valid interpretable results.

A descriptive study of effect-size reporting in research reviews.

PubMed

Floyd, Judith A

2017-06-01

To describe effect-size reporting in research reviews completed in support of evidence-based practice in nursing. Many research reviews report nurses' critical appraisal of level, quality and overall strength of evidence available to address clinical questions. Several studies of research-review quality suggest effect-size information would be useful to include in these reviews, but none focused on reviewers' attention to effect sizes. Descriptive. One hundred and four reviews indexed in CINAHL as systematic reviews and published from July 2012-February 2014 were examined. Papers were required to be peer-reviewed, written in English, contain an abstract and have at least one nurse author. Reviews were excluded if they did not use critical appraisal methods to address evidence of correlation, prediction or effectiveness. Data from remaining papers (N = 73) were extracted by three or more independent coders using a structured coding form and detailed codebook. Data were stored, viewed and analysed using Microsoft Office Excel ® spreadsheet functions. Sixteen percent (n = 12) of the sample contained effect-size information. Of the 12, six included all the effect-size information recommended by APA guidelines. Independent of completeness of reporting, seven contained discussion of effect sizes in the paper, but none included effect-size information in abstracts. Research reviews available to practicing nurses often fail to include information needed to accurately assess how much improvement may result from implementation of evidence-based policies, programs, protocols or practices. Manuscript reviewers are urged to hold authors to APA standards for reporting/discussing effect-size information in both primary research reports and research reviews. © 2016 John Wiley & Sons Ltd.

Three essays on the economics of science policy: The impact of funding, collaboration and research chairs

NASA Astrophysics Data System (ADS)

Mirnezami, Seyed Reza

This thesis studies the determinants that influence the number of citations, the effect of having a research collaboration with top-funded scientists on scientific productivity, and the effect of holding a research chair on scientific productivity. Based on a review study by Bornmann and Daniel (2008), one can argue that non-scientific factors determining the decision to cite do not significantly alter the role of citation as a measure of research impact. Assuming that the number of citations is a good measure for research impact and, in turn, for a certain kind of quality, we showed that the number of articles and the visibility of a researcher, the impact factor of the journal, the size of the research team, and the institutional setting of the university are the important determinants of citation counts. However, we have found that there is no significant effect of public funding and gender in most of the domains examined. The point that funding amount is not a significant determinant of citation counts does not necessarily contradict the positive effect of funding on scientific productivity. We also developed a theoretical model and proposed some hypotheses about the effect of collaboration with top-funded scientists on scientific productivity. We then validated the hypotheses with empirical analysis and showed that such collaboration has a positive effect on scientific productivity. This significant effect may exist through different channels: transfer of tacit knowledge, more scientific publications, economy of scale in knowledge production because of better research equipment, and expanded research network. The results also verified the positive effect of funding, the positive effect of networking (measured by number of co-authors), the inverted U-shaped effect of age, and the fewer number of publications by women compared to men. Finally, we made a distinction between different attributes of research chairs and their effect on scientific productivity. One of the important questions is to find out whether a research chair still has better scientific productivity (compared to non-chair holders) after controlling for the research funds available to the researchers. To investigate that question, we employed a matching technique to identify pairs of scientists (chair and non-chair holders) of the same gender, funding and research field. After such matching, we found that the effect of the Canada research chair program on scientific productivity remains significant and positive, while the effect of industrial chairs and the chairs appointed by the Canadian federal granting councils (NSERC and CIHR) become non-significant. This finding highlights the effectiveness of our matching technique methodology; because before matching, holding any type of chair had a positive and significant effect on scientific productivity. This finding highlights the special attributes of the Canada research chair program, which are not replicated in other chairs. Those specific attributes may significantly push scientific productivity. For example, Canada research chairs are generally associated with some degree of prestige or higher visibility to recruit talented students or to have research collaboration with top scientists in the field. In addition, the Canada research chair program has a firm and efficient method of allocation (which is explained in the thesis). This approach institutionally synchronizes different chairs in universities and research fields. The fact that other types of research chairs, once matched with equivalent scientists, do not have an impact on scientific output in terms of quantity does not imply that these chair holders are lesser scientists, but that they are devoting part of their time to other endeavours of a more practical nature. Hence universities are maintaining a balance between the pursuit of pure scientific knowledge and its application to socioeconomic benefits. By solely studying scientific articles, we are missing a great deal of the university professors' activities. Although not trivial, future research should aim to cast a wider net on outputs, outcomes and impacts of university research.

2014-01-01

Online knowledge resources such as Medline can address most clinicians’ patient care information needs. Yet, significant barriers, notably lack of time, limit the use of these sources at the point of care. The most common information needs raised by clinicians are treatment-related. Comparative effectiveness studies allow clinicians to consider multiple treatment alternatives for a particular problem. Still, solutions are needed to enable efficient and effective consumption of comparative effectiveness research at the point of care. Objective Design and assess an algorithm for automatically identifying comparative effectiveness studies and extracting the interventions investigated in these studies. Methods The algorithm combines semantic natural language processing, Medline citation metadata, and machine learning techniques. We assessed the algorithm in a case study of treatment alternatives for depression. Results Both precision and recall for identifying comparative studies was 0.83. A total of 86% of the interventions extracted perfectly or partially matched the gold standard. Conclusion Overall, the algorithm achieved reasonable performance. The method provides building blocks for the automatic summarization of comparative effectiveness research to inform point of care decision-making. PMID:23920677

Guidelines to support nurse-researchers reflect on role conflict in qualitative interviewing.

PubMed

Jack, Susan

2008-01-01

The conduct of a qualitative research interview is a complex social interaction that has the potential to influence, or be influenced by, both the researcher and the study participant. When a researcher is identified as a professional nurse, the identification of this role has the potential to influence the researcher-participant interaction. To understand the effect of a nurse-researcher's involvement in an in-depth interview and on the data collected, issues to address include: clearly identifying the paradigmatic approach in which the research design is situated, examining the study participants' past experiences with research and the researcher's profession, establishing appropriate boundaries with participants, deciding how to introduce the role of nurse-researcher to the participant and deciding if, or when, it would be appropriate to intervene within the research context. As nurse-researchers, professional knowledge and experiences have the potential to affect relationship development with study participants and obfuscate the purpose of the research interview. It is the researcher's responsibility to participate in the activity of reflexivity to understand the effect of the nurse-researcher's involvement on the data and make decisions that protect the participant's integrity.

A systematic review of social networking sites: innovative platforms for health research targeting adolescents and young adults.

PubMed

Park, Bu Kyung; Calamaro, Christina

2013-09-01

To review the evidence to determine if social networking sites (SNS) are effective tools for health research in the adolescent and young adult populations. Systematic review of published research articles focused on use of SNS for youth health research. Seventeen articles were selected that met the following criteria: used SNS at any stage of study, participants between 13 and 25 years of age, English language, and both international and national studies. Reviewers categorized selected studies based on the way SNS were used. Utilization of SNS for effectively implementing research with adolescents and young adults include (a) recruitment, (b) intervention, and (c) measurement. Four findings about advantages of using SNS apparent in this review are (a) ease of access to youth, (b) cost effectiveness in recruitment, (c) ease of intervention, and (d) reliable screening venue of mental status and high-risk behaviors. Although this literature review showed relatively minimal research to date on the use of SNS for research targeting adolescents and young adults, the impact of using SNS for health research is of considerable importance for researchers as well as participants. With careful focus, SNS can become a valuable platform to access, recruit, and deliver health interventions in a cost-effective manner to youth populations as well as hard-to-reach minority or underserved populations. The evidence demonstrates the usefulness of SNS as innovative platforms for health promotion among adolescents and young adults. © 2013 Sigma Theta Tau International.

Demand artifact: objectively detecting biased participants in advertising research.

Miller, Felicia; Schertzer, Susan

2014-12-01

Detecting and reducing the effect of biased participants continues to be an important task for researchers. However, the lack of objective measures to assess demand artifact has made it difficult to effectively address this issue. This paper reports two experiments that apply a theory-based post-experimental inquiry that can systematically identify biased participants in consumer research. The results demonstrate how easily and effectively researchers can incorporate this tool into experimental studies of all types and reduce the likelihood of systematic error.

Can a science-based definition of acupuncture improve clinical outcomes?

PubMed

Priebe, Ted; Stumpf, Steven H; Zalunardo, Rod

2017-05-01

Research on acupuncture has been muddled by attempts to bridge the ancient with the modern. Barriers to effectiveness research are reflected in recurring conflicts that include disagreement on use of the most basic terms, lack of standard intervention controls, and the absence of functional measures for assessing treatment effect. Acupuncture research has stalled at the "placebo barrier" wherein acupuncture is "no better than placebo." The most widely recognized comparative effectiveness research in acupuncture does not compare acupuncture treatment protocols within groups, thereby, mutating large scale effectiveness studies into large scale efficacy trials. Too often research in acupuncture attempts to tie outcomes to traditional belief systems thereby limiting usefulness of the research. The acupuncture research paradigm needs to focus more closely on a scientific definition of treatments and outcomes that compare protocols in terms of prevalent clinical issues such as relative effectiveness for treating pain.

In many research groups, Microsoft Excel and Access are the usual data management tools, but they are very basic and do not support any automation, linking, or reminder systems to manage and integrate recruitment information and processes. We explored whether a commercial customer relationship management (CRM) software program - designed for sales people in businesses to improve customer relations and communications - could be used to make the research recruitment system faster, more effective, and more efficient. We found that while there was potential for long-term studies, it simply did not adapt effectively enough for our shorter study and recruitment budget. The amount of training required to master the software and our need for ongoing flexible and timely support were greater than the benefit of using CRM software for our study.

Academic detailing can play a key role in assessing and implementing comparative effectiveness research findings.

Fischer, Michael A; Avorn, Jerry

Comparative effectiveness research evaluates the relative effectiveness, safety, and value of competing treatment options in clinically realistic settings. Such evaluations can be methodologically complex and difficult to interpret. There will be a growing need for critical evaluation of comparative effectiveness studies to assess the adequacy of their design and to put new information into a broader context. Equally important, this knowledge will have to be communicated to clinicians in a way that will actually change practice. We identify three challenges to effective dissemination of comparative effectiveness research findings: the difficulty of interpreting comparative effectiveness research data, the need for trusted sources of information, and the challenge of turning research results into clinical action. We suggest that academic detailing-direct outreach education that gives clinicians an accurate and unbiased synthesis of the best evidence for practice in a given clinical area-can translate comparative effectiveness research findings into actions that improve health care decision making and patient outcomes.

Effectiveness-implementation hybrid designs: combining elements of clinical effectiveness and implementation research to enhance public health impact.

PubMed

Curran, Geoffrey M; Bauer, Mark; Mittman, Brian; Pyne, Jeffrey M; Stetler, Cheryl

2012-03-01

This study proposes methods for blending design components of clinical effectiveness and implementation research. Such blending can provide benefits over pursuing these lines of research independently; for example, more rapid translational gains, more effective implementation strategies, and more useful information for decision makers. This study proposes a "hybrid effectiveness-implementation" typology, describes a rationale for their use, outlines the design decisions that must be faced, and provides several real-world examples. An effectiveness-implementation hybrid design is one that takes a dual focus a priori in assessing clinical effectiveness and implementation. We propose 3 hybrid types: (1) testing effects of a clinical intervention on relevant outcomes while observing and gathering information on implementation; (2) dual testing of clinical and implementation interventions/strategies; and (3) testing of an implementation strategy while observing and gathering information on the clinical intervention's impact on relevant outcomes. The hybrid typology proposed herein must be considered a construct still in evolution. Although traditional clinical effectiveness and implementation trials are likely to remain the most common approach to moving a clinical intervention through from efficacy research to public health impact, judicious use of the proposed hybrid designs could speed the translation of research findings into routine practice.

Research Assistants Caught in Limbo: Considering Their Role in Quantitative, Longitudinal Research with Vulnerable Populations.

Research assistants (RAs) play a variety of roles that are critical in making research happen and in determining its quality and effectiveness. Yet their locus of power in the production of knowledge stands in sharp contrast to their relative powerlessness in the hierarchical research organization. This article explores the experiences of RAs engaged in a randomized controlled longitudinal field trial of a Housing First intervention for individuals experiencing homelessness and mental illness in Toronto. They encountered several unexpected effects of navigating the power ascribed to them by both study participants and community service providers. This study underscores the importance of acknowledging that RAs are the face of the research study in the field, and of better understanding implications associated with that fact, especially when marginalized populations and their providers are involved.

Improper food handling by consumers at home is a major cause of foodborne illness. Therefore, effective education strategies are essential to change consumers' food safety attitudes and behaviors. The purpose of this scoping review was to identify and characterize primary literature examining the effectiveness of consumer food-safety education interventions. Ten bibliographic databases were searched using a comprehensive search strategy. Citations were identified; two reviewers screened them for relevance and characterized relevant articles. To ensure results would be applicable to end users, stakeholders were engaged to provide input on the review scope, methods, and results. We identified 246 relevant articles, of which 150 were quantitative, 66 qualitative, and 30 mixed-method research studies. Most studies (64.2%) were published in the United States, using an uncontrolled before-and-after study design (31.3%), and investigated the effectiveness of community-based training sessions and workshops (52.0%). Research gaps were found in the number of randomized controlled studies conducted, academic- and school-based courses and curricula investigated, and interventions targeting high-risk populations (e.g., pregnant women, those who are immunocompromised) and using new media channels (e.g., social media). Key opportunities to enhance the utility of future primary research investigating consumer food-safety interventions include the following: using studies based on behavior-change theories and formative research; engaging the target population in the research; using validated instruments to measures outcomes; and reporting intervention characteristics and outcomes completely. Results of this review can be used to prioritize future primary research and decision-making in this area.

McCormick, L K; Crawford, M; Anderson, R H; Gittelsohn, J; Kingsley, B; Upson, D

1999-03-01

An increasing barrier to the development and implementation of effective youth smoking prevention and cessation programs involves recruiting adolescents into research studies. Even for non-intervention studies, issues of consent, confidentiality, and motivation to participate are important considerations. In 1996, 11 Prevention Research Center sites across the country conducted qualitative research using focus groups to explore ethnic differences in smoking among adolescents. The diversity in strategies used to interest, motivate, and retain potential focus group subjects provided a rich data set for information about effective strategies and challenges to recruitment. This article presents an overview of recruitment methods used in a multi-site qualitative study on adolescent tobacco use, reports on successful and less successful strategies, and provides recommendations for future recruitment.

Miller, Lucy Jane; Schoen, Sarah A; James, Katherine; Schaaf, Roseann C

2007-01-01

The purpose of this pilot study was to prepare for a randomized controlled study of the effectiveness of occupational therapy using a sensory integration approach (OT-SI) with children who have sensory processing disorders (SPD). A one-group pretest, posttest design with 30 children was completed with a subset of children with SPD, those with sensory modulation disorder. Lessons learned relate to (a) identifying a homogeneous sample with quantifiable inclusion criteria, (b) developing an intervention manual for study replication and a fidelity to treatment measure, (c) determining which outcomes are sensitive to change and relate to parents' priorities, and (d) clarifying rigorous methodologies (e.g., blinded examiners, randomization, power). A comprehensive program of research is needed, including multiple pilot studies to develop enough knowledge that high-quality effectiveness research in occupational therapy can be completed. Previous effectiveness studies in OT-SI have been single projects not based on a unified long-term program of research.

p-Curve and p-Hacking in Observational Research.

PubMed

Bruns, Stephan B; Ioannidis, John P A

2016-01-01

The p-curve, the distribution of statistically significant p-values of published studies, has been used to make inferences on the proportion of true effects and on the presence of p-hacking in the published literature. We analyze the p-curve for observational research in the presence of p-hacking. We show by means of simulations that even with minimal omitted-variable bias (e.g., unaccounted confounding) p-curves based on true effects and p-curves based on null-effects with p-hacking cannot be reliably distinguished. We also demonstrate this problem using as practical example the evaluation of the effect of malaria prevalence on economic growth between 1960 and 1996. These findings call recent studies into question that use the p-curve to infer that most published research findings are based on true effects in the medical literature and in a wide range of disciplines. p-values in observational research may need to be empirically calibrated to be interpretable with respect to the commonly used significance threshold of 0.05. Violations of randomization in experimental studies may also result in situations where the use of p-curves is similarly unreliable.

Acute effects of tea consumption on attention and mood.

PubMed

Einöther, Suzanne J; Martens, Vanessa E

2013-12-01

Tea has historically been associated with mood and performance benefits, such as relaxation and concentration. This review summarizes the research on the acute effects of tea, and its ingredients theanine and caffeine, on attention and mood. Consistent with abundant research on the benefits of caffeine, the performance benefits of tea were identified in a number of studies, with particularly consistent evidence for improved attention. Tea consumption also consistently improved self-reported alertness and arousal, whereas effects on pleasure or relaxation were less consistent. In addition to the research on caffeine in real-life performance, 2 recent studies have provided a broader perspective on tea's effects on psychological function in that they showed beneficial effects in related areas such as work performance and creativity. These studies showed the validity of laboratory findings by supporting the idea that tea consumption has acute benefits on both mood and performance in real-life situations.

Information asymmetry, social networking site word of mouth, and mobility effects on social commerce in Korea.

PubMed

Hwang, In Jeong; Lee, Bong Gyou; Kim, Ki Youn

2014-02-01

The purpose of this research is to examine the issues that affect customers' behavioral character and purchasing behavior. The study proposes a research hypothesis with independent variables that include social presence, trust, and information asymmetry, and the dependent variable purchase decision making, to explain differentiated customer decision making processes in social commerce (S-commerce). To prove the hypothesis, positive verification was performed by focusing on mediating effects through a customer uncertainty variable and moderating effects through mobility and social networking site word of mouth (SNS WOM) variables. The number of studies on customer trends has rapidly increased together with the market size of S-commerce. However, few studies have examined the negative variables that make customers hesitant to make decisions in S-commerce. This study investigates the causes of customer uncertainty and focuses on deducing the control variables that offset this negative relationship. The study finds that in customers' S-commerce purchasing actions, the SNS WOM and mobility variables show control effects between information asymmetry and uncertainty and between trust and uncertainty. Additionally, this research defines the variables related to customer uncertainty that are hidden in S-commerce, and statistically verifies their relationship. The research results can be used in Internet marketing practices to establish marketing mix strategies for customer demand or as research data to predict customer behavior. The results are scientifically meaningful as a precedent for research on customers in S-commerce.

Recruitment of Individuals With Dementia and Their Carers for Social Research: Lessons Learned From Nine Studies.

PubMed

Beattie, Elizabeth; Fielding, Elaine; O'Reilly, Maria; Brooks, Deborah; MacAndrew, Margaret; McCrow, Judy

2018-05-01

Many health and social care research studies report difficulties recruiting sufficient numbers of participants, adding to time and money expenditures and potentially jeopardizing the generalizability of findings. The current article reports the effectiveness and resource requirements of recruitment strategies used in nine dementia-related studies conducted in Australia. Articles, notices, or advertisements in targeted specialist newsletters were the most cost-effective method of recruitment. The use of service providers to aid recruitment yielded mixed results, but was lengthy in terms of research time. Online and social media were low cost but not reliably effective in terms of recruitment potential. Despite using multiple strategies to maximize recruitment, significant challenges were encountered achieving the required sample sizes; in most cases these challenges resulted in delays in the recruitment phase. Implications for researchers in the fields of dementia and general social/health research are discussed. [Res Gerontol Nurs. 2018; 11(3):119-128.]. Copyright 2018, SLACK Incorporated.

Wi-Fi and health: review of current status of research.

PubMed

Foster, Kenneth R; Moulder, John E

2013-12-01

This review summarizes the current state of research on possible health effects of Wi-Fi (a commercial name for IEEE 802.11-compliant wireless networking). In response to public concerns about health effects of Wi-Fi and wireless networks and calls by government agencies for research on possible health and safety issues with the technology, a considerable amount of technology-specific research has been completed. A series of high quality engineering studies have provided a good, but not complete, understanding of the levels of radiofrequency (RF) exposure to individuals from Wi-Fi. The limited number of technology-specific bioeffects studies done to date are very mixed in terms of quality and outcome. Unequivocally, the RF exposures from Wi-Fi and wireless networks are far below U.S. and international exposure limits for RF energy. While several studies report biological effects due to Wi-Fi-type exposures, technical limitations prevent drawing conclusions from them about possible health risks of the technology. The review concludes with suggestions for future research on the topic.

Botswana water and surface energy balance research program. Part 2: Large scale moisture and passive microwaves

NASA Technical Reports Server (NTRS)

Vandegriend, A. A.; Owe, M.; Chang, A. T. C.

1992-01-01

The Botswana water and surface energy balance research program was developed to study and evaluate the integrated use of multispectral satellite remote sensing for monitoring the hydrological status of the Earth's surface. The research program consisted of two major, mutually related components: a surface energy balance modeling component, built around an extensive field campaign; and a passive microwave research component which consisted of a retrospective study of large scale moisture conditions and Nimbus scanning multichannel microwave radiometer microwave signatures. The integrated approach of both components are explained in general and activities performed within the passive microwave research component are summarized. The microwave theory is discussed taking into account: soil dielectric constant, emissivity, soil roughness effects, vegetation effects, optical depth, single scattering albedo, and wavelength effects. The study site is described. The soil moisture data and its processing are considered. The relation between observed large scale soil moisture and normalized brightness temperatures is discussed. Vegetation characteristics and inverse modeling of soil emissivity is considered.

Effectiveness of health-promoting media literacy education: a systematic review.

PubMed

Bergsma, Lynda J; Carney, Mary E

2008-06-01

Media literacy education to promote health among youth involves them in a critical examination of media messages that promote risky behaviors and influence their perceptions and practices. Research on its effectiveness is in its infancy. Studies to date have been conducted with more or less rigor and achieved differing results, leaving many questions about effectiveness unanswered. To elucidate some of these questions, we conducted a systematic review of selected health-promoting media literacy education evaluation/research studies, guided by the following research question: What are the context and process elements of an effective health-promoting media literacy education intervention? Based on extensive analysis of 28 interventions, our findings provide a detailed picture of a small, 16- to 17-year (1990 to July 2006) body of important research, including citation information, health issue, target population/N/age, research design, intervention length and setting, concepts/skills taught, who delivered the intervention and ratings of effectiveness. The review provides a framework for organizing research about media literacy education which suggests that researchers should be more explicit about the media literacy core concepts/skills they are including in their interventions, and should more carefully address who delivered the intervention with what fidelity, in what setting, for how long and utilizing what pedagogical approach.

Observational methods in comparative effectiveness research.

PubMed

Concato, John; Lawler, Elizabeth V; Lew, Robert A; Gaziano, J Michael; Aslan, Mihaela; Huang, Grant D

2010-12-01

Comparative effectiveness research (CER) may be defined informally as an assessment of available options for treating specific medical conditions in selected groups of patients. In this context, the most prominent features of CER are the various patient populations, medical ailments, and treatment options involved in any particular project. Yet, each research investigation also has a corresponding study design or "architecture," and in patient-oriented research a common distinction used to describe such designs are randomized controlled trials (RCTs) versus observational studies. The purposes of this overview, with regard to CER, are to (1) understand how observational studies can provide accurate results, comparable to RCTs; (2) recognize strategies used in selected newer methods for conducting observational studies; (3) review selected observational studies from the Veterans Health Administration; and (4) appreciate the importance of fundamental methodological principles when conducting or evaluating individual studies.

Does involvement in a cohort study improve health and affect health inequalities? A natural experiment.

Quick, Annie; Böhnke, Jan R; Wright, John; Pickett, Kate E

2017-01-25

Evidence suggests that the process of taking part in health research can improve participants' health, independent of any intended intervention. However, no research has yet explored whether these effects differ across socioeconomic groups. If the effect of mere participation in health research also has a social gradient this could increase health inequalities and bias research results. This study used the Born in Bradford family cohort (BIB) to explore whether simply taking part in BIB had improved participants' health and, if so, whether this effect was mediated by socioeconomic status. Survey data on self-reported health behaviours were collected between 2007 and 2010 as part of BIB. These were augmented by clinical data on birth weight. Pregnant women on their second pregnancy, joining BIB for the first time formed the control group. Their health was compared to women on their second pregnancy who had both pregnancies within the study, who formed the exposed group. In order to limit the inherent bias in a non-randomised study, propensity score analysis was used, matching on age, ethnicity, education and date of questionnaire. The results were then compared according to mothers' education. Of six outcomes tested, only alcohol consumption showed a statistically significant reduction with exposure to BIB (OR: 0.35, 95% CIs 0.13, 0.92). Although effect estimates were larger for women with higher education compared to lower education, these effects were not statistically significant. Despite one significant finding, these results overall are insufficient to conclude that simply taking part in BIB affected participants' health. We recommend that socioeconomic status is considered in future studies testing effects of research participation, and that randomised studies with larger sample sizes are conducted.

Programs to reduce teen pregnancy, sexually transmitted infections, and associated sexual risk behaviors: a systematic review.

Goesling, Brian; Colman, Silvie; Trenholm, Christopher; Terzian, Mary; Moore, Kristin

2014-05-01

This systematic review provides a comprehensive, updated assessment of programs with evidence of effectiveness in reducing teen pregnancy, sexually transmitted infections (STIs), or associated sexual risk behaviors. The review was conducted in four steps. First, multiple literature search strategies were used to identify relevant studies released from 1989 through January 2011. Second, identified studies were screened against prespecified eligibility criteria. Third, studies were assessed by teams of two trained reviewers for the quality and execution of their research designs. Fourth, for studies that passed the quality assessment, the review team extracted and analyzed information on the research design, study sample, evaluation setting, and program impacts. A total of 88 studies met the review criteria for study quality and were included in the data extraction and analysis. The studies examined a range of programs delivered in diverse settings. Most studies had mixed-gender and predominately African-American research samples (70% and 51%, respectively). Randomized controlled trials accounted for the large majority (87%) of included studies. Most studies (76%) included multiple follow-ups, with sample sizes ranging from 62 to 5,244. Analysis of the study impact findings identified 31 programs with evidence of effectiveness. Research conducted since the late 1980s has identified more than two dozen teen pregnancy and STI prevention programs with evidence of effectiveness. Key strengths of this research are the large number of randomized controlled trials, the common use of multiple follow-up periods, and attention to a broad range of programs delivered in diverse settings. Two main gaps are a lack of replication studies and the need for more research on Latino youth and other high-risk populations. In addressing these gaps, researchers must overcome common limitations in study design, analysis, and reporting that have negatively affected prior research.

The effects of medication use in transcranial direct current stimulation: A brief review.

PubMed

McLaren, Molly E; Nissim, Nicole R; Woods, Adam J

There has been increased interest in the potential use of transcranial direct current stimulation (tDCS) as treatment for multiple conditions including depression, pain, and cognitive impairment. However, few studies account for the possible influence of comorbid medications when conducting tDCS research. This literature review was conducted to examine what is currently known about the impact of medications on tDCS, provide recommendations for future research practices, and highlight areas where more research is needed. Key terms were searched in PubMed and Web of Science to identify studies that examine the impact of medication on tDCS effects in adults. Relevant papers' reference lists were also reviewed for thoroughness. Studies examined the effects of medication on 1 mA tDCS delivered to M1 (motor) and orbit/supraorbital (SO) area. All studies measured the effects of tDCS via MEP TMS paradigm. Results of the literature review suggest multiple classes of medications, including sodium and calcium channel blockers, and medications that influence various neurotransmitter systems (GABA, dopamine, serotonin, etc.) may all impact tDCS effects on tissue excitability. Research to date suggests multiple classes of medications may impact tDCS effects. These results highlight the importance of documenting medication use in research subjects and carefully considering what types of medications should be allowed into tDCS trials. Many questions still remain regarding the exact mechanisms of action for tDCS and how various parameters (medication dosages, tDCS stimulation intensity, etc.) may further impact the effects of medications on tDCS.

To describe the inaugural comparative effectiveness research (CER) cohort study of Washington State's Comparative Effectiveness Research Translation Network (CERTAIN), which compares invasive with noninvasive treatments for peripheral artery disease, and to focus on the patient centeredness of this cohort study by describing it within the context of a newly published conceptual framework for patient-centered outcomes research (PCOR). The peripheral artery disease study was selected because of clinician-identified uncertainty in treatment selection and differences in desired outcomes between patients and clinicians. Patient centeredness is achieved through the "Patient Voices Project," a CERTAIN initiative through which patient-reported outcome (PRO) instruments are administered for research and clinical purposes, and a study-specific patient advisory group where patients are meaningfully engaged throughout the life cycle of the study. A clinician-led research advisory panel follows in parallel. Primary outcomes are PRO instruments that measure function, health-related quality of life, and symptoms, the latter developed with input from the patients. Input from the patient advisory group led to revised retention procedures, which now focus on short-term (3-6 months) follow-up. The research advisory panel is piloting a point-of-care, patient assessment checklist, thereby returning study results to practice. The cohort study is aligned with the tenets of one of the new conceptual frameworks for conducting PCOR. The CERTAIN's inaugural cohort study may serve as a useful model for conducting PCOR and creating a learning health care network. Copyright © 2013 Elsevier Inc. All rights reserved.

From bench to bedside and to health policies: ethics in translational research.

PubMed

Petrini, C

2011-01-01

Translation of biomedical research knowledge to effective clinical treatment is essential to the public good. The first level of translation ("from bench to bedside") corresponds to efficacy studies under controlled conditions with careful attention to internal validity (clinical research). The second level is the translation of results from clinical studies into everyday clinical practice and health decision making. The article summarises the ethical issues involved in the translation of biomedical research advances to clinical applications and to clinical practice. In particular, the article synthesizes theory from clinical ethics, operational design, and philosophy to examine the unique bioethical issues raised by the recent focus on translational research. In this framework safety of study participants and balancing of risk due to treatment with the potential benefits of the research are crucial: in clinical research there is a danger that the emphasis on advancements in scientific knowledge might prevail over the protection of the people who participate in research. These issues involve basic scientists, clinicians and bioethicists because of their application to comparative effectiveness research, clinical trials and evidence-based medicine, as well basic biomedical research.

The influence of risk and monetary payment on the research participation decision making process

PubMed Central

Bentley, J; Thacker, P

2004-01-01

Objectives: To determine the effects of risk and payment on subjects' willingness to participate, and to examine how payment influences subjects' potential behaviours and risk evaluations. Methods: A 3 (level of risk) x 3 (level of monetary payment), between subjects, completely randomised factorial design was used. Students enrolled at one of five US pharmacy schools read a recruitment notice and informed consent form for a hypothetical study, and completed a questionnaire. Risk level was manipulated using recruitment notices and informed consent documents from hypothetical biomedical research projects. Payment levels were determined using the payment models evaluated by Dickert and Grady as a guide. Five dependent variables were assessed in the questionnaire: willingness to participate, willingness to participate with no payment, propensity to neglect to tell about restricted activities, propensity to neglect to tell about negative effects, and risk rating. Results: Monetary payment had positive effects on respondents' willingness to participate in research, regardless of the level of risk. However, higher monetary payments did not appear to blind respondents to the risks of a study. Payment had some influence on respondents' potential behaviours regarding concealing information about restricted activities. However, payment did not appear to have a significant effect on respondents' propensity to neglect to tell researchers about negative effects. Conclusions: Monetary payments appear to do what they are intended to do: make subjects more willing to participate in research. Concerns about payments blinding subjects to risks could not be substantiated in the present study. However, the findings do raise other concerns—notably the potential for payments to diminish the integrity of a study's findings. Future research is critical to make sound decisions about the payment of research subjects. PMID:15173366

2017-02-01

To evaluate the feasibility, appropriateness, meaningfulness and effectiveness of bedside shift reporting in a minimum of five interventions and five control wards. Hospitals continually improve their quality of care. Next to improvements in clinical performance, more patient participation is stimulated through different methods. Methods to enhance patient participation such as bedside shift reporting lack rigorously performed research to determine their feasibility, appropriateness, meaningfulness and effectiveness. Small-scale research and a previous pilot study indicate that bedside shift reporting improves patient participation, nurse-nurse communication and nurse-patient communication. The development, implementation and evaluation of bedside shift report are based on the Medical Research Council framework for complex interventions in health care. A matched, controlled, mixed-method, longitudinal study design will be used. The Feasibility-Appropriateness-Meaningfulness-Effectiveness framework will be applied for the quantitative and qualitative evaluation of bedside shift report. A tailored intervention and implementation process for bedside shift report will be developed using diagnostic interviews, co-design and acceptability testing. The intervention will be evaluated before implementation and three times after implementation. Individual and focus group interviews will be performed. Questionnaires, observations and analysis of the medical records and administrative databases will be completed. This study was funded in October 2015. Research Ethics Committee approval was granted in March 2016. There is a pressing need for rigorous research into the effects of interventions for improving patient participation. This study addresses the significance of bedside shift report as an intervention to improve quality of care, communication and patient participation within a large-scale, matched, controlled research design. © 2016 John Wiley & Sons Ltd.

The need for econometric research in laboratory animal operations.

PubMed

Baker, David G; Kearney, Michael T

2015-06-01

The scarcity of research funding can affect animal facilities in various ways. These effects can be evaluated by examining the allocation of financial resources in animal facilities, which can be facilitated by the use of mathematical and statistical methods to analyze economic problems, a discipline known as econometrics. The authors applied econometrics to study whether increasing per diem charges had a negative effect on the number of days of animal care purchased by animal users. They surveyed animal numbers and per diem charges at 20 research institutions and found that demand for large animals decreased as per diem charges increased. The authors discuss some of the challenges involved in their study and encourage research institutions to carry out more robust econometric studies of this and other economic questions facing laboratory animal research.

Latinos with obsessive-compulsive disorder: Mental healthcare utilization and inclusion in clinical trials.

Previous research has documented that ethnic minorities, particularly Latinos, obtain fewer mental health services than Caucasians (Kearney, Draper, & Baron 2005; Sue, Fujino, Hu, Takeuchi, & Zane, 1991). Conceivably, this may be due to a wide array of cultural issues (e.g., negative stigma attached to mental health, and language, socio-economic, and acculturation barriers), symptom disparities across Caucasian and Latino groups, or lack of effective outreach methods by clinicians and researchers. However, research is limited. As a result, Latinos may be insufficiently represented in clinical studies for OCD, making it unclear whether evidence-based treatments demonstrate the same efficacy and effectiveness for Latinos as has been demonstrated for Caucasians. The current study takes an in-depth analysis of 98 efficacy and effectiveness studies for OCD from across the Western hemisphere and reports the rates of Latino inclusion from each sample. Ninety clinical studies in the US and Canada, as well as eight clinical studies in Mexico and Central America were reviewed. Findings showed that only 11 (24%) US and Canadian studies included Latino participants, illustrating an overwhelming underrepresentation of Latinos in clinical studies for OCD. Further explanation of the results and their implications are discussed, along with suggestions for effectively improving access to mental health research and appropriate treatments.

The effects of energy beverages in counteracting the symptoms of mild hypoxia at legal general aviation altitudes

NASA Astrophysics Data System (ADS)

Bull, Daniel Mark

The purpose of this thesis was to conduct preliminary research, in the form of a pilot study, concerning the natural effects of hypoxia compared to the effects of hypoxia experienced after the consumption of an energy beverage. The study evaluated the effects of hypoxia on FAA certificated pilots at a simulated legal general aviation altitude, utilizing the normobaric High Altitude Lab (HAL) located at Embry Riddle Aeronautical University, Daytona Beach, Florida. The researcher tested 11 subjects, who completed three simulated flight tasks within the HAL using the Frasca International Mentor Advanced Aviation Training Device (AATD). The flight tasks were completed after consuming Red BullRTM, MonsterRTM , or a placebo beverage. The researcher derived three test variables from core outputs of the AATD: lateral deviations from the glide slope, vertical deviations from the localizer, and airspeed deviations from the target speed of 100 knots. A repeated-measures ANOVA was carried out to determine effects of the beverages on the test variables. While results were non-significant, the researcher concluded that further research should be conducted with a larger sample.

To what extent do site-based training, mentoring, and operational research improve district health system management and leadership in low- and middle-income countries: a systematic review protocol.

2016-04-27

District health managers play a key role in the effectiveness of decentralized health systems in low- and middle-income countries. Inadequate management and leadership skills often hamper their ability to improve quality of care and effectiveness of health service delivery. Nevertheless, significant investments have been made in capacity-building programmes based on site-based training, mentoring, and operational research. This systematic review aims to review the effectiveness of site-based training, mentoring, and operational research (or action research) on the improvement of district health system management and leadership. Our secondary objectives are to assess whether variations in composition or intensity of the intervention influence its effectiveness and to identify enabling and constraining contexts and underlying mechanisms. We will search the following databases: MEDLINE, PsycInfo, Cochrane Library, CRD database (DARE), Cochrane Effective Practice and Organisation of Care (EPOC) group, ISI Web of Science, Health Evidence.org, PDQ-Evidence, ERIC, EMBASE, and TRIP. Complementary search will be performed (hand-searching journals and citation and reference tracking). Studies that meet the following PICO (Population, Intervention, Comparison, Outcome) criteria will be included: P: professionals working at district health management level; I: site-based training with or without mentoring, or operational research; C: normal institutional arrangements; and O: district health management functions. We will include cluster randomized controlled trials, controlled before-and-after studies, interrupted time series analysis, quasi-experimental designs, and cohort and longitudinal studies. Qualitative research will be included to contextualize findings and identify barriers and facilitators. Primary outcomes that will be reported are district health management and leadership functions. We will assess risk of bias with the Cochrane Collaboration's tools for randomized controlled trials (RCT) and non RCT studies and Critical Appraisal Skills Programme checklists for qualitative studies. We will assess strength of recommendations with the GRADE tool for quantitative studies, and the CERQual approach for qualitative studies. Synthesis of quantitative studies will be performed through meta-analysis when appropriate. Best fit framework synthesis will be used to synthesize qualitative studies. This protocol paper describes a systematic review assessing the effectiveness of site-based training (with or without mentoring programmes or operational research) on the improvement of district health system management and leadership.

Sun, Maxine; Lipsitz, Stuart R

2018-04-01

The use of secondary data, such as claims or administrative data, in comparative effectiveness research has grown tremendously in recent years. We believe that the current review can help investigators relying on secondary data to (1) gain insight into both the methodologies and statistical methods, (2) better understand the necessity of a rigorous planning before initiating a comparative effectiveness investigation, and (3) optimize the quality of their investigations. Specifically, we review concepts of adjusted analyses and confounders, methods of propensity score analyses, and instrumental variable analyses, risk prediction models (logistic and time-to-event), decision-curve analysis, as well as the interpretation of the P value and hypothesis testing. Overall, we hope that the current review article can help research investigators relying on secondary data to perform comparative effectiveness research better understand the necessity of a rigorous planning before study start, and gain better insight in the choice of statistical methods so as to optimize the quality of the research study.

Recent developments in research and treatment for social phobia (social anxiety disorder).

PubMed

Cottraux, Jean

2005-01-01

This review covers three themes of research that brought fresh data useful for clinical practice in a handicapping anxiety disorder: social phobia. Recent findings deriving from basic biological research, new forms of psychological therapies, and recent psychopharmacology controlled trials are reviewed. The basic neuroimaging research suggests that greater activation of the amygdala to novel versus familiar faces may be an underlying trait marker for social phobia. Social phobia may represent a phenotype that expresses a genetically driven trait of social withdrawal, which may be related to infantile inhibited temperament (Kagan's syndrome). The development of virtual reality therapy as therapeutic tool for social phobia appeared promising in one controlled, but not randomized, study. A controlled study suggests that social phobias in children can be effectively treated with cognitive behavioural therapy. This represents an extension of the work done with adults. Venlafaxine appears an effective short-term treatment for social anxiety disorder in two controlled studies. A new compound, pregabalin, appeared clearly effective in a positive controlled study. This trial marks the advent of a new pharmacological lineage for social phobia. Both venlafaxine and pregabalin, however, have been studied in short-term studies. Longer follow-up and relapse prevention studies are warranted. Neuroimaging research points to a temperamental basis for social phobia. Virtual reality therapy is an emerging tool to carry out exposure treatment. Group cognitive behavioural therapy can be extended successfully to children. Venlafaxine and pregabalin have a proven short-term effectiveness in social phobia.

Research on homeopathy: state of the art.

PubMed

Walach, Harald; Jonas, Wayne B; Ives, John; van Wijk, Roel; Weingärtner, Otto

2005-10-01

In this paper, we review research on homeopathy from four perspectives, focusing on reviews and some landmark studies. These perspectives are laboratory studies, clinical trials, observational studies, and theoretical work. In laboratory models, numerous effects and anomalies have been reported. However, no single model has been sufficiently widely replicated. Instead, researchers have focused on ever-new models and experiments, leaving the picture of scattered anomalies without coherence. Basic research, trying to elucidate a purported difference between homeopathic remedies and control solutions has also produced some encouraging results, but again, series of independent replications are missing. While there are nearly 200 reports on clinical trials, few series have been conducted for single conditions. Some of these series document clinically useful effects and differences against placebo and some series do not. Observational research into uncontrolled homeopathic practice documents consistently strong therapeutic effects and sustained satisfaction in patients. We suggest that this scattered picture has to do with the fourth line of research: lack of a good theory. Some of the extant theoretical models are reviewed, including placebo, water structure, silica contamination, energy models, and entanglement models. It emerges that local models, suggesting some change in structure in the solvent, are far from convincing. The nonlocal models proposed would predict that it is impossible to nail down homeopathic effects with direct experimental testing and this places homeopathy in a scientific dilemma. We close with some suggestions for potentially fruitful research.

One implication for evidenced-based nursing practice would be to educate family and friends on the signs of depression and how to respond to them. A suggestion for future research would be to conduct a study showing the effectiveness of different treatment methods (e.g., therapy, medications) on adolescent depression.

Effect of drug reminder packaging on medication adherence: a systematic review revealing research gaps

PubMed Central

2014-01-01

Background This was a systematic review of the literature in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Evidence mapping was used to reveal the effect of drug reminder packaging on medication adherence, to identify research gaps and to make suggestions for future research. Methods PubMed, Embase, CINAHL and PsycINFO were searched with an end date of September 2013 using the Medical Subject Headings (MeSH) term ‘medication adherence’ and 20 different search terms for ‘drug reminder packaging’, limited to the English and German languages. Additional references were identified through cross-referencing. All prospective controlled trials with an intervention using drug reminder packaging for patients taking at least one medication without the assistance of a health-care professional were included in the evidence mapping of the effect of drug reminder packaging on adherence and outcomes according to the Economic, Clinical and Humanistic Outcomes (ECHO) model. Results A total of 30 studies met the inclusion criteria: 10 randomized controlled trials, 19 controlled clinical trials and 1 cohort study. Drug reminder packaging had a significant effect on at least one adherence parameter in 17 studies (57%). The methodological quality was strong in five studies. Two studies provided complete information. Clear research gaps emerged. Conclusions Overall, the studies showed a positive effect of drug reminder packaging on adherence and clinical outcomes. However, poor reporting and important gaps like missing humanistic and economic outcomes and neglected safety issues limit the drawing of firm conclusions. Suggestions are made for future research.

2016-11-10

Current Alzheimer's disease (AD) research initiatives focus on cognitively healthy individuals with biomarkers that are associated with the development of AD. It is unclear whether biomarker results should be returned to research participants and what the psychological, behavioral and social effects of disclosure are. This systematic review therefore examines the psychological, behavioral and social effects of disclosing genetic and nongenetic AD-related biomarkers to cognitively healthy research participants. We performed a systematic literature search in eight scientific databases. Three independent reviewers screened the identified records and selected relevant articles. Results extracted from the included articles were aggregated and presented per effect group. Fourteen studies met the inclusion criteria and were included in the data synthesis. None of the identified studies examined the effects of disclosing nongenetic biomarkers. All studies but one concerned the disclosure of APOE genotype and were conducted in the USA. Study populations consisted largely of cognitively healthy first-degree relatives of AD patients. In this group, disclosure of an increased risk was not associated with anxiety, depression or changes in perceived risk in relation to family history. Disclosure of an increased risk did lead to an increase in specific test-related distress levels, health-related behavior changes and long-term care insurance uptake and possibly diminished memory functioning. In cognitively healthy research participants with a first-degree relative with AD, disclosure of APOE ε4-positivity does not lead to elevated anxiety and depression levels, but does increase test-related distress and results in behavior changes concerning insurance and health. We did not find studies reporting the effects of disclosing nongenetic biomarkers and only one study included people without a family history of AD. Empirical studies on the effects of disclosing nongenetic biomarkers and of disclosure to persons without a family history of AD are urgently needed.

"Lies, damned lies ..." and observational studies in comparative effectiveness research.

PubMed

Albert, Richard K

2013-06-01

A new federal initiative has allocated $1.1 billion to comparative effectiveness research, and many have emphasized the importance of including observational studies in this effort. The rationale for using observational studies to assess comparative effectiveness is based on concerns that randomized controlled trials (RCTs) are not "real world" because they enroll homogeneous patient populations, measure study outcomes that are not important to patients, use protocols that are overly complex, are conducted in specialized centers, and use study treatments that are not consistent with usual care, and that RCTs are not always feasible because of a lack of equipoise, the need to assess delayed endpoints, and concerns that they take years to complete and are expensive. This essay questions the validity of each of these proposed limitations, summarizes concerns raised about the accuracy of results generated by observational studies, provides some examples of discrepancies between results of observational studies and RCTs that pertain to pulmonary and critical care, and suggests that using observational studies for comparative effectiveness research may increase rather than decrease the cost of health care and may harm patients.

Chen, Qian; Ai, Ni; Liao, Jie; Shao, Xin; Liu, Yufeng; Fan, Xiaohui

2017-01-01

Valuable scientific results on biomedicine are very rich, but they are widely scattered in the literature. Topic modeling enables researchers to discover themes from an unstructured collection of documents without any prior annotations or labels. In this paper, taking ginseng as an example, biological dynamic topic model (Bio-DTM) was proposed to conduct a retrospective study and interpret the temporal evolution of the research of ginseng. The system of Bio-DTM mainly includes four components, documents pre-processing, bio-dictionary construction, dynamic topic models, topics analysis and visualization. Scientific articles pertaining to ginseng were retrieved through text mining from PubMed. The bio-dictionary integrates MedTerms medical dictionary, the second edition of side effect resource, a dictionary of biology and HGNC database of human gene names (HGNC). A dynamic topic model, a text mining technique, was used to emphasize on capturing the development trends of topics in a sequentially collected documents. Besides the contents of topics taken on, the evolution of topics was visualized over time using ThemeRiver. From the topic 9, ginseng was used in dietary supplements and complementary and integrative health practices, and became very popular since the early twentieth century. Topic 6 reminded that the planting of ginseng is a major area of research and symbiosis and allelopathy of ginseng became a research hotspot in 2007. In addition, the Bio-DTM model gave an insight into the main pharmacologic effects of ginseng, such as anti-metabolic disorder effect, cardioprotective effect, anti-cancer effect, hepatoprotective effect, anti-thrombotic effect and neuroprotective effect. The Bio-DTM model not only discovers what ginseng's research involving in but also displays how these topics evolving over time. This approach can be applied to the biomedical field to conduct a retrospective study and guide future studies.

Research Guidelines in the Era of Large-scale Collaborations: An Analysis of Genome-wide Association Study Consortia

PubMed Central

Austin, Melissa A.; Hair, Marilyn S.; Fullerton, Stephanie M.

2012-01-01

Scientific research has shifted from studies conducted by single investigators to the creation of large consortia. Genetic epidemiologists, for example, now collaborate extensively for genome-wide association studies (GWAS). The effect has been a stream of confirmed disease-gene associations. However, effects on human subjects oversight, data-sharing, publication and authorship practices, research organization and productivity, and intellectual property remain to be examined. The aim of this analysis was to identify all research consortia that had published the results of a GWAS analysis since 2005, characterize them, determine which have publicly accessible guidelines for research practices, and summarize the policies in these guidelines. A review of the National Human Genome Research Institute’s Catalog of Published Genome-Wide Association Studies identified 55 GWAS consortia as of April 1, 2011. These consortia were comprised of individual investigators, research centers, studies, or other consortia and studied 48 different diseases or traits. Only 14 (25%) were found to have publicly accessible research guidelines on consortia websites. The available guidelines provide information on organization, governance, and research protocols; half address institutional review board approval. Details of publication, authorship, data-sharing, and intellectual property vary considerably. Wider access to consortia guidelines is needed to establish appropriate research standards with broad applicability to emerging forms of large-scale collaboration. PMID:22491085

The effect of music on cognitive performance: insight from neurobiological and animal studies.

PubMed

Rickard, Nikki S; Toukhsati, Samia R; Field, Simone E

2005-12-01

The past 50 years have seen numerous claims that music exposure enhances human cognitive performance. Critical evaluation of studies across a variety of contexts, however, reveals important methodological weaknesses. The current article argues that an interdisciplinary approach is required to advance this research. A case is made for the use of appropriate animal models to avoid many confounds associated with human music research. Although such research has validity limitations for humans, reductionist methodology enables a more controlled exploration of music's elementary effects. This article also explores candidate mechanisms for this putative effect. A review of neurobiological evidence from human and comparative animal studies confirms that musical stimuli modify autonomic and neurochemical arousal indices, and may also modify synaptic plasticity. It is proposed that understanding how music affects animals provides a valuable conjunct to human research and may be vital in uncovering how music might be used to enhance cognitive performance.

Virtual reality exposure therapy for the treatment of anxiety disorders: an evaluation of research quality.

PubMed

McCann, Russell A; Armstrong, Christina M; Skopp, Nancy A; Edwards-Stewart, Amanda; Smolenski, Derek J; June, Jennifer D; Metzger-Abamukong, Melinda; Reger, Greg M

2014-08-01

Randomized controlled trials (RCTs) support the effectiveness of virtual reality exposure therapy (VRET) for anxiety disorders; however, the overall quality of the VRET RCT literature base has yet to be evaluated. This study reviewed 27 VRET RCTs and the degree of adherence to 8 RCT research design criteria derived from existing standards. Adherence to the study quality criteria was generally low as the articles met an average 2.85 criteria (SD=1.56). None of the studies met more than six quality criteria. Study quality did not predict effect size; however, a reduction in effect size magnitude was observed for studies with larger sample sizes when comparing VRET to non-active control groups. VRET may be an effective method of treatment but caution should be exercised in interpreting the existing body of literature supporting VRET relative to existing standards of care. The need for well-designed VRET research is discussed. Copyright © 2014. Published by Elsevier Ltd.

Interventions targeting substance abuse among women survivors of intimate partner abuse: a meta-analysis.

PubMed

Fowler, Dawnovise N; Faulkner, Monica

2011-12-01

In this article, meta-analytic techniques are used to examine existing intervention studies (n = 11) to determine their effects on substance abuse among female samples of intimate partner abuse (IPA) survivors. This research serves as a starting point for greater attention in research and practice to the implementation of evidence-based, integrated services to address co-occurring substance abuse and IPA victimization among women as major intersecting public health problems. The results show greater effects in three main areas. First, greater effect sizes exist in studies where larger numbers of women experienced current IPA. Second, studies with a lower mean age also showed greater effect sizes than studies with a higher mean age. Lastly, studies with smaller sample sizes have greater effects. This research helps to facilitate cohesion in the knowledge base on this topic, and the findings of this meta-analysis, in particular, contribute needed information to gaps in the literature on the level of promise of existing interventions to impact substance abuse in this underserved population.

The Single-Group, Pre- and Posttest Design in Nursing Education Research: It's Time to Move on.

PubMed

Spurlock, Darrell R

2018-02-01

Studying the effectiveness of educational interventions is centrally important to building the science of nursing education. Yet, the design most commonly used in the study of nursing education interventions-the single-group, preand posttest design-provides limited evidence to support claims of intervention effectiveness. In this Methodology Corner installment, the limitations of the single-group, preand posttest design are outlined and a review of the requirements for establishing stronger arguments for causality is presented. To overcome the limitations of single-group, preand posttest designs, nursing education researchers are encouraged to employ study designs and procedures that can significantly strengthen researchers' claims of intervention effectiveness.

Understaning the "funding effect"

NASA Astrophysics Data System (ADS)

Oreskes, N.

2016-12-01

There is a long history of industry funding of scientific and engineering research in the USA. Much of this work has been of high quality. Research demonstrates, however, that corporate funding can represent a threat to scientific independence and integrity. Studies show that sponsors' interests can affect research results, particularly when sponsors have a strong interest in a particular research outcome. The effects may occur through the impact of subconscious bias on sampling, study design, data interpretation, and/or reporting of results. Corporate funding can also skew research toward investigating certain questions at the expense of others, downplaying the significance of adverse findings, and/or failing to report adverse results. Gifts can affect behavior, even when they are unrelated to research activities. These impacts that are so substantial that they have a name: "the funding effect."[i] Evidence shows that scientists who strive to be objective and fair-minded may nonetheless fall prey to the funding effect. In many cases, the challenges of corporate gifts and funding can be addressed through education and improved self-awareness, agreements that protect researchers' freedom to publish without sponsor approval, sensible disclosure policies, and reasonable sanctions for failures of disclosure. However, in some cases, it may be appropriate for researchers and scientific societies to decline funding.

Factors influencing the effectiveness of research ethics committees.

PubMed

Schuppli, C A; Fraser, D

2007-05-01

Research ethics committees - animal ethics committees (AECs) for animal-based research and institutional research boards (IRBs) for human subjects - have a key role in research governance, but there has been little study of the factors influencing their effectiveness. The objectives of this study were to examine how the effectiveness of a research ethics committee is influenced by committee composition and dynamics, recruitment of members, workload, participation level and member turnover. As a model, 28 members of AECs at four universities in western Canada were interviewed. Committees were selected to represent variation in the number and type of protocols reviewed, and participants were selected to include different types of committee members. We found that a bias towards institutional or scientific interests may result from (1) a preponderance of institutional and scientist members, (2) an intimidating atmosphere for community members and other minority members, (3) recruitment of community members who are affiliated with the institution and (4) members joining for reasons other than to fulfil the committee mandate. Thoroughness of protocol review may be influenced by heavy workloads, type of review process and lack of full committee participation. These results, together with results from the literature on research ethics committees, suggested potential ways to improve the effectiveness of research ethics committees.

The sequence of events in a behaviour change trial involves interactions between research participants and the trial process. Taking part in such a study has the potential to influence the behaviour of the participant, and if it does, this can engender bias in trial outcomes. Since participants' experience has received scant attention, the aim of this study is thus to generate hypotheses about which aspects of the conduct of behaviour change trials might matter most to participants, and thus have potential to alter subsequent behaviours and bias trial outcomes Twenty participants were opportunistically screened for a health compromising behaviour (unhealthy diet, lack of exercise, smoking or alcohol consumption) and recruited if eligible. Semi structured face to face interviews were conducted, after going through the usual processes involved in trial recruitment, baseline assessment and randomisation. Participants were given information on the contents of an intervention or control condition in a behaviour change trial, which was not actually implemented. Three months later they returned to reflect on these experiences and whether they had any effect on their behaviour during the intervening period. Data from the latter interview were analysed thematically using a modified grounded theory approach. The early processes of trial participation raised awareness of unhealthy behaviours, although most reported having had only fleeting intentions to change their behaviour as a result of taking part in this study, in the absence of interventions. However, careful examination of the accounts revealed evidence of subtle research participation effects, which varied according to the health behaviour, and its perceived social acceptability. Participants' relationships with the research study were viewed as somewhat important in stimulating thinking about whether and how to make lifestyle changes. These participants described no dramatic impacts attributable to taking part in this study. This study demonstrates the likely value of well conducted qualitative studies of subtle research participation effects, which may be particularly important to explore for alcohol. Separating unintended influences in trial participation from the effects of behaviour change interventions being evaluated therein is necessary for valid estimates of intervention effects.

The World Health Organization's Framework Convention on Tobacco Control recommends prominent pictorial health warnings on tobacco products. To advance research methods, theory and understanding of how tobacco product warning labels (TPWLs) work, the US National Cancer Institute convened a grantee meeting. Our article describes the key insights that emerged from the meeting, situated within the context of the scientific literature. First, presentations confirmed that large, pictorial TPWLs motivate people to try to quit and encourage smoking cessation. Second, pictorial TPWLs increase attention, knowledge, negative affect, and thinking about the warning. Third, TPWL studies have primarily used brief-exposure laboratory studies and observational studies of sustained exposure through national policy implementation, with a few randomized trials involving several weeks of exposure-with generally consistent results found across study designs. Fourth, novel assessment methods include brain imaging, eye tracking and "best-worst" discrete choice experiments. To make TPWL even more effective, research is needed to confirm the mechanisms of their influence, their impact across vulnerable populations, and their effect on social media posts about tobacco products. Research is also needed on the effect of trial design choices, the predictive validity of new measurement approaches, and warning labels for non-cigarette tobacco products. To improve scientific understanding of TPWL effects, this grantee meeting summary describes emerging research methods, theory and study results. Directions for future research include examination of the mechanisms of how warning labels work across diverse tobacco products and across different populations and contexts.

Since 2012, PCORI has been funding patient-centered comparative effectiveness research with a requirement for engaging patients and other stakeholders in the research, a requirement that is unique among the US funders of clinical research. This paper presents PCORI's evaluation framework for assessing the short- and long-term impacts of engagement; describes engagement in PCORI projects (types of stakeholders engaged, when in the research process they are engaged and how they are engaged, contributions of their engagement); and identifies the effects of engagement on study design, processes, and outcomes selection, as reported by both PCORI-funded investigators and patient and other stakeholder research partners. Detailed quantitative and qualitative information collected annually from investigators and their partners was analyzed via descriptive statistics and cross-sectional qualitative content and thematic analysis, and compared against the outcomes expected from the evaluation framework and its underlying conceptual model. The data support the role of engaged research partners in refinements to the research questions, selection of interventions to compare, choice of study outcomes and how they are measured, contributions to strategies for recruitment, and ensuring studies are patient-centered. The evaluation framework and the underlying conceptual model are supported by results to date. PCORI will continue to assess the effects of engagement as the funded projects progress toward completion, dissemination, and uptake into clinical decision making.

The Drawbacks of Project Funding for Epistemic Innovation: Comparing Institutional Affordances and Constraints of Different Types of Research Funding.

Franssen, Thomas; Scholten, Wout; Hessels, Laurens K; de Rijcke, Sarah

2018-01-01

Over the past decades, science funding shows a shift from recurrent block funding towards project funding mechanisms. However, our knowledge of how project funding arrangements influence the organizational and epistemic properties of research is limited. To study this relation, a bridge between science policy studies and science studies is necessary. Recent studies have analyzed the relation between the affordances and constraints of project grants and the epistemic properties of research. However, the potentially very different affordances and constraints of funding arrangements such as awards, prizes and fellowships, have not yet been taken into account. Drawing on eight case studies of funding arrangements in high performing Dutch research groups, this study compares the institutional affordances and constraints of prizes with those of project grants and their effects on organizational and epistemic properties of research. We argue that the prize case studies diverge from project-funded research in three ways: 1) a more flexible use, and adaptation of use, of funds during the research process compared to project grants; 2) investments in the larger organization which have effects beyond the research project itself; and 3), closely related, greater deviation from epistemic and organizational standards. The increasing dominance of project funding arrangements in Western science systems is therefore argued to be problematic in light of epistemic and organizational innovation. Funding arrangements that offer funding without scholars having to submit a project-proposal remain crucial to support researchers and research groups to deviate from epistemic and organizational standards.

[Advance in researches on the effect of forest on hydrological process].

Zhang, Zhiqiang; Yu, Xinxiao; Zhao, Yutao; Qin, Yongsheng

2003-01-01

According to the effects of forest on hydrological process, forest hydrology can be divided into three related aspects: experimental research on the effects of forest changing on hydrological process quantity and water quality; mechanism study on the effects of forest changing on hydrological cycle, and establishing and exploitating physical-based distributed forest hydrological model for resource management and engineering construction. Orientation experiment research can not only support the first-hand data for forest hydrological model, but also make clear the precipitation-runoff mechanisms. Research on runoff mechanisms can be valuable for the exploitation and improvement of physical based hydrological models. Moreover, the model can also improve the experimental and runoff mechanism researches. A review of above three aspects are summarized in this paper.

Knowledge translation tools for parents on child health topics: a scoping review.

PubMed

Albrecht, Lauren; Scott, Shannon D; Hartling, Lisa

2017-09-29

An emerging field of knowledge translation (KT) research has begun to focus on health consumers, particularly in child health. KT tools provide health consumers with research knowledge to inform health decision-making and may foster 'effective consumers'. Thus, the purpose of this scoping review was to describe the state of the field of previously published effectiveness research on child health-related KT tools for parents/caregivers to understand the evidence-base, identify gaps, and guide future research efforts. A health research librarian developed and implemented search strategies in 8 databases. One reviewer conducted screening using pre-determined criteria. A second reviewer verified 10% of screening decisions. Data extraction was performed by one reviewer. A descriptive analysis was conducted and included patient-important outcome classification, WIDER Recommendation checklist, and methodological quality assessment. Seven thousand nine hundred fifty two independent titles and abstracts were reviewed, 2267 full-text studies were retrieved and reviewed, and 18 articles were included in the final data set. A variety of KT tools, including single- (n = 10) and multi-component tools (n = 10), were evaluated spanning acute (n = 4), chronic (n = 5) and public/population health (n = 9) child health topics. Study designs included: cross-sectional (n = 4), before-after (n = 1), controlled before-after (n = 2), cohort (n = 1), and RCTs (n = 10). The KT tools were evaluated via single primary outcome category (n = 11) and multiple primary outcome categories (n = 7). Two studies demonstrated significant positive effects on primary outcome categories; the remaining studies demonstrated mixed effects (n = 9) and no effect (n = 3). Overall, methodological quality was poor; studies lacked a priori protocols (n = 18) and sample size calculations (n = 13). Overall, intervention reporting was also poor; KT tools lacked description of theoretical underpinnings (n = 14), end-user engagement (n = 13), and preliminary research (n = 9) to inform the current effectiveness evaluation. A number of child health-related knowledge translation tools have been developed for parents/caregivers. However, numerous outcomes were used to assess impact and there is limited evidence demonstrating their effectiveness. Moreover, the methodological rigor and reporting of effectiveness studies is limited. Careful tool development involving end-users and preliminary research, including usability testing and mixed methods, prior to large-scale studies may be important to advance the science of KT for health consumers.

In this review, 39 articles published in the American journal of occupational therapy in 2008 and 2009 that were categorized in the practice area of children and youth were examined using content analysis. The most frequent type of research published was basic research, which accounted for 38.5% (n=15) of the 39 studies published on the topic. Instrument development and testing and effectiveness studies were the next two most frequently noted research approaches, accounting for 25.6% (n=10) and 20.5% (n=8) of the studies, respectively. Among the 8 effectiveness studies, the level of evidence distribution was as follows: Level I, 3; Level III, 2; Level IV, 1; and Level V, 2. Quantitative studies were the predominant research paradigm used with 76.9% (n=30) of the studies.

Objectives To assess the effects of taking an intercalated degree (BSc) on the study habits and learning styles of medical students and on their interest in a career in medical research. Design Longitudinal questionnaire study of medical students at application to medical school and in their final year. Setting All UK medical schools. Participants 6901 medical school applicants for admission in 1991 were studied in the autumn of 1990. 3333 entered medical school in 1991 or 1992, and 2695 who were due to qualify in 1996 or 1997 were studied 3 months before the end of their clinical course. Response rates were 92% for applicants and 56% for final year students. Main outcome measures Study habits (surface, deep, and strategic learning style) and interest in different medical careers, including medical research. Identical questions were used at time of application and in final year. Results Students who had taken an intercalated degree had higher deep and strategic learning scores than at application to medical school. Those with highest degree classes had higher strategic and deep learning scores and lower surface learning scores. Students taking intercalated degrees showed greater interest in careers in medical research and laboratory medicine and less interest in general practice than their peers. The effects of the course on interest in medical research and learning styles were independent. The effect of the intercalated degree was greatest in schools where relatively few students took intercalated degrees. Conclusions Intercalated degrees result in a greater interest in research careers and higher deep and strategic learning scores. However, the effects are much reduced in schools where most students intercalate a degree. Introduction of intercalated degrees for all medical students without sufficient resources may not therefore achieve its expected effects. Key messagesAlthough intercalated degrees are well established, little is known about their effect on medical studentsIn this longitudinal study final year students who had taken intercalated degree were more interested in medical research, and had higher deep and strategic learning style scores than other studentsThe effects of the intercalated degree were dose dependent, being greatest in those gaining a first class degreeThe effects of the intercalated degree were greatest in medical schools where a relatively small proportion of medical students took the degree.Differences between medical schools are most easily explained by resource dilution PMID:10463892

Guidelines to Support Nurse-Researchers Reflect on Role Conflict in Qualitative Interviewing

PubMed Central

Jack, Susan

2008-01-01

The conduct of a qualitative research interview is a complex social interaction that has the potential to influence, or be influenced by, both the researcher and the study participant. When a researcher is identified as a professional nurse, the identification of this role has the potential to influence the researcher-participant interaction. To understand the effect of a nurse-researcher’s involvement in an in-depth interview and on the data collected, issues to address include: clearly identifying the paradigmatic approach in which the research design is situated, examining the study participants' past experiences with research and the researcher’s profession, establishing appropriate boundaries with participants, deciding how to introduce the role of nurse-researcher to the participant and deciding if, or when, it would be appropriate to intervene within the research context. As nurse-researchers, professional knowledge and experiences have the potential to affect relationship development with study participants and obfuscate the purpose of the research interview. It is the researcher’s responsibility to participate in the activity of reflexivity to understand the effect of the nurse-researcher’s involvement on the data and make decisions that protect the participant’s integrity.

Facts and fallacies of purported ergogenic amino acid supplements.

PubMed

Williams, M H

1999-07-01

Although current research suggests that individuals involved in either high-intensity resistance or endurance exercise may have an increased need for dietary protein, the available research is either equivocal or negative relative to the ergogenic effects of supplementation with individual amino acids. Although some research suggests that the induction of hyperaminoacidemia via intravenous infusion of a balanced amino acid mixture may induce an increased muscle protein synthesis after exercise, no data support the finding that oral supplementation with amino acids, in contrast to dietary protein, as the source of amino acids is more effective. Some well-controlled studies suggest that aspartate salt supplementation may enhance endurance performance, but other studies do not, meriting additional research. Current data, including results for several well-controlled studies, indicated that supplementation with arginine, ornithine, or lysine, either separately or in combination, does not enhance the effect of exercise stimulation on either hGH or various measures of muscular strength or power in experienced weightlifters. Plasma levels of BCAA and tryptophan may play important roles in the cause of central fatigue during exercise, but the effects of BCAA or tryptophan supplementation do not seem to be effective ergogenics for endurance exercise performance, particularly when compared with carbohydrate supplementation, a more natural choice. Although glutamine supplementation may increase plasma glutamine levels, its effect on enhancement of the immune system and prevention of adverse effects of the overtraining syndrome are equivocal. Glycine, a precursor for creatine, does not seem to possess the ergogenic potential of creatine supplementation. Research with metabolic by-products of amino acid metabolism is in its infancy, and current research findings are equivocal relative to ergogenic applications. In general, physically active individuals are advised to obtain necessary amino acids through consumption of natural, high-quality protein foods.

Alcohol portrayals in movies, music videos and soap operas and alcohol use of young people: current status and future challenges.

Koordeman, Renske; Anschutz, Doeschka J; Engels, Rutger C M E

2012-01-01

To provide an overview of studies of the effects of alcohol portrayals in movies, music videos and soap operas on alcohol consumption among young people. Moreover, we highlight important issues that need to be addressed in future research. This paper reviews the current literature on alcohol portrayals on-screen and the associated gaps and challenges in alcohol media research. Thirteen longitudinal studies, 8 cross-sectional studies and 6 experimental studies examined the effects of alcohol portrayals on-screen on alcohol consumption among young people. They showed a relation between on-screen alcohol exposure and onset and progression of alcohol consumption. A distinction can be made between long-term effects and immediate effects on alcohol consumption. Only lately, more attention has been paid to processes underlying the effects of on-screen alcohol exposure. Replication of findings and development of new research designs is essential. On-screen alcohol exposure does not affect everyone. It is important to test individual differences in susceptibility to on-screen alcohol portrayals. Further, not all media alcohol portrayal might provoke similar effects. It is therefore essential to test the effect of different types of alcohol portrayals.

Nicholls, Stuart G; Hayes, Tavis P; Brehaut, Jamie C; McDonald, Michael; Weijer, Charles; Saginur, Raphael; Fergusson, Dean

2015-01-01

To date there is no established consensus of assessment criteria for evaluating research ethics review. We conducted a scoping review of empirical research assessing ethics review processes in order to identify common elements assessed, research foci, and research gaps to aid in the development of assessment criteria. Electronic searches of Ovid Medline, PsychInfo, and the Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA, and NHSEED, were conducted. After de-duplication, 4234 titles and abstracts were reviewed. Altogether 4036 articles were excluded following screening of titles, abstracts and full text. A total of 198 articles included for final data extraction. Few studies originated from outside North America and Europe. No study reported using an underlying theory or framework of quality/effectiveness to guide study design or analyses. We did not identify any studies that had involved a controlled trial--randomised or otherwise--of ethics review procedures or processes. Studies varied substantially with respect to outcomes assessed, although tended to focus on structure and timeliness of ethics review. Our findings indicate a lack of consensus on appropriate assessment criteria, exemplified by the varied study outcomes identified, but also a fragmented body of research. To date research has been largely quantitative, with little attention given to stakeholder experiences, and is largely cross sectional. A lack of longitudinal research to date precludes analyses of change or assessment of quality improvement in ethics review.

Political Ideology, Confidence in Science, and Participation in Alzheimer Disease Research Studies.

PubMed

Gabel, Matthew; Gooblar, Jonathan; Roe, Catherine M; Selsor, Natalie J; Morris, John C

2018-01-18

Americans' confidence in science varies based on their political ideology. This ideological divide has potentially important effects on citizens' engagement with and participation in clinical studies of Alzheimer disease (AD). A probability sample of 1583 Americans was surveyed about their willingness to participate in longitudinal AD research and about their political attitudes. These survey results were compared with a survey of 382 participants in a longitudinal AD study at the Knight Alzheimer Disease Research Center. Among Americans, more conservative ideology decreases willingness to participate in a hypothetical longitudinal cohort study of AD both directly and through its negative effect on confidence in science. The Knight Alzheimer Disease Research Center study participants expressed more liberal ideology and greater confidence in science than Americans in general. Of the survey respondents opposed to participation, over a quarter changed to neutral or positive if the study returned their research results to them. Clinical studies of AD are likely biased toward participants who are more liberal and have higher confidence in science than the general population. This recruitment bias may be reduced by lowering the trust demanded of participants through measures such as returning research results to participants.

Evaluation of Conceptual Frameworks Applicable to the Study of Isolation Precautions Effectiveness

Crawford, Catherine; Shang, Jingjing

2015-01-01

Aims A discussion of conceptual frameworks applicable to the study of isolation precautions effectiveness according to Fawcett and DeSanto-Madeya’s (2013) evaluation technique and their relative merits and drawbacks for this purpose Background Isolation precautions are recommended to control infectious diseases with high morbidity and mortality, but effectiveness is not established due to numerous methodological challenges. These challenges, such as identifying empirical indicators and refining operational definitions, could be alleviated though use of an appropriate conceptual framework. Design Discussion paper Data Sources In mid-April 2014, the primary author searched five electronic, scientific literature databases for conceptual frameworks applicable to study isolation precautions, without limiting searches by publication date. Implications for Nursing By reviewing promising conceptual frameworks to support isolation precautions effectiveness research, this paper exemplifies the process to choose an appropriate conceptual framework for empirical research. Hence, researchers may build on these analyses to improve study design of empirical research in multiple disciplines, which may lead to improved research and practice. Conclusion Three frameworks were reviewed: the epidemiologic triad of disease, Donabedian’s healthcare quality framework and the Quality Health Outcomes model. Each has been used in nursing research to evaluate health outcomes and contains concepts relevant to nursing domains. Which framework can be most useful likely depends on whether the study question necessitates testing multiple interventions, concerns pathogen-specific characteristics and yields cross-sectional or longitudinal data. The Quality Health Outcomes model may be slightly preferred as it assumes reciprocal relationships, multi-level analysis and is sensitive to cultural inputs. PMID:26179813

Economic assessment of the construction industry: A construction-economics nexus

NASA Astrophysics Data System (ADS)

Barber, Herbert Marion, Jr.

The purpose of this study was to conduct an economic assessment of the construction industry. More specifically, this study addresses ambiguities within the literature that are associated with the construction-economics nexus. The researcher 1) investigated the relationships between economic indicators and stock prices of U.S. construction equipment manufacturers, 2) investigated the relationships between energy production, consumption, and corruption, and 3) determined the economic effect electricity generation and electricity consumption has on economies of scale. The researcher used descriptive and inferential statistics in this study and determined that economists, researchers, policy-makers, and others should have predicted the 2007-08 world economic collapse 5-6 years prior to realization of the event given that construction indices and GDP grossly regressed from statistically acceptable trends as early as 2002 and perhaps 2000. Substantiating this claim, the effect of the cost of construction materials and labor, i.e. construction index, on GDP was significant for years leading up to the collapse (1970-2007). Additionally, it was determined that energy production and consumption are predictors of governmental corruption in some countries. In the Republic of Botswana, for example, the researcher determined that energy production and consumption statistically jointly effected governmental corruption. In addition to determining statistical effect, a model for predicting governmental corruption was developed based on energy production and consumption volumes. Also, the researcher found that electricity generation in the 25 largest world economies had a statistically significant effect on GDP. Electricity consumption also had an effect on GDP, as well, but not on other economic indicators. More importantly than the quantitative findings, the researcher concluded that the construction-economics nexus is far more complex than most policy-makers realize. As such, infrastructure spending may, or may not, be an answer to the current world economic collapse, as much more research remains to be completed by researchers to address known ambiguities within various associated findings. Until a collective agreement can be reached among researchers as to the effect that construction spending has on economic output under known, specific parameters, policy-makers should exercise extreme caution when leveraging infrastructure spending as a solution for overcoming the world economic collapse.

Effectiveness-implementation Hybrid Designs

PubMed Central

Curran, Geoffrey M.; Bauer, Mark; Mittman, Brian; Pyne, Jeffrey M.; Stetler, Cheryl

2013-01-01

Objectives This study proposes methods for blending design components of clinical effectiveness and implementation research. Such blending can provide benefits over pursuing these lines of research independently; for example, more rapid translational gains, more effective implementation strategies, and more useful information for decision makers. This study proposes a “hybrid effectiveness-implementation” typology, describes a rationale for their use, outlines the design decisions that must be faced, and provides several real-world examples. Results An effectiveness-implementation hybrid design is one that takes a dual focus a priori in assessing clinical effectiveness and implementation. We propose 3 hybrid types: (1) testing effects of a clinical intervention on relevant outcomes while observing and gathering information on implementation; (2) dual testing of clinical and implementation interventions/strategies; and (3) testing of an implementation strategy while observing and gathering information on the clinical intervention’s impact on relevant outcomes. Conclusions The hybrid typology proposed herein must be considered a construct still in evolution. Although traditional clinical effectiveness and implementation trials are likely to remain the most common approach to moving a clinical intervention through from efficacy research to public health impact, judicious use of the proposed hybrid designs could speed the translation of research findings into routine practice.

2015-01-01

Emergency Department (ED) student-based research assistant programs have been shown to be effective in enrolling patients when the students receive university course credit or pay. However, the impact on research outcomes when university students act as volunteers in this role is relatively unknown. The main objective of this study was to determine how often potentially eligible children were accurately identified by volunteer research assistants for enrollment into prospective research in the ED. We also examined the frequency of successful enrollments and the accuracy of data capture. This was a prospective cross-sectional study of university student volunteer research assistant performance in a tertiary care pediatric ED between March 2011 and July 2013. The participant's primary role was to screen and facilitate enrollment of ED patients into clinical research. For each volunteer, we recorded demographics, number of screenings, enrollments, and data capture accuracy. Over five 6-month sessions, 151 student volunteers participated. Of these, 77.3% were female, 58.8% were undergraduate students, and 61.1% were interested in medical school. Student volunteers accurately screened 11,362/13,067 (87.0%) children, and they accurately identified 4407/4984 (88.4%) potentially eligible children for study enrollment. Of the 3805 eligible for enrollment exclusively by the students, 3228 (84.8%) families/children consented and completed all study procedures. Furthermore, students correctly entered 11,660/12,567 (92.8%) data points. Utilizing university student volunteers to facilitate research enrollment in the ED is effective and allows for the capture of a high percentage of potentially eligible patients into prospective clinical research studies.

2015-12-01

Research projects in translational science are increasingly complex and require interdisciplinary collaborations. In the context of training translational researchers, this suggests that multiple mentors may be needed in different content areas. This study explored mentoring structure as it relates to perceived mentoring effectiveness and other characteristics of master's-level trainees in clinical-translational research training programs. A cross-sectional online survey of recent graduates of clinical research master's program was conducted. Of 73 surveys distributed, 56.2% (n = 41) complete responses were analyzed. Trainees were overwhelmingly positive about participation in their master's programs and the impact it had on their professional development. Overall the majority (≥75%) of trainees perceived they had effective mentoring in terms of developing skills needed for conducting clinical-translational research. Fewer trainees perceived effective mentoring in career development and work-life balance. In all 15 areas of mentoring effectiveness assessed, higher rates of perceived mentor effectiveness was seen among trainees with ≥2 mentors compared to those with solo mentoring (SM). In addition, trainees with ≥2 mentors perceived having effective mentoring in more mentoring aspects (median: 14.0; IQR: 12.0-15.0) than trainees with SM (median: 10.5; IQR: 8.0-14.5). Results from this survey suggest having ≥2 mentors may be beneficial in fulfilling trainee expectations for mentoring in clinical-translational training. © 2015 Wiley Periodicals, Inc.

p-Curve and p-Hacking in Observational Research

PubMed Central

Bruns, Stephan B.; Ioannidis, John P. A.

2016-01-01

The p-curve, the distribution of statistically significant p-values of published studies, has been used to make inferences on the proportion of true effects and on the presence of p-hacking in the published literature. We analyze the p-curve for observational research in the presence of p-hacking. We show by means of simulations that even with minimal omitted-variable bias (e.g., unaccounted confounding) p-curves based on true effects and p-curves based on null-effects with p-hacking cannot be reliably distinguished. We also demonstrate this problem using as practical example the evaluation of the effect of malaria prevalence on economic growth between 1960 and 1996. These findings call recent studies into question that use the p-curve to infer that most published research findings are based on true effects in the medical literature and in a wide range of disciplines. p-values in observational research may need to be empirically calibrated to be interpretable with respect to the commonly used significance threshold of 0.05. Violations of randomization in experimental studies may also result in situations where the use of p-curves is similarly unreliable. PMID:26886098

2007-09-01

To systematically review the research evidence on the effectiveness of hypnosis for cancer chemotherapy-induced nausea and vomiting (CINV). A comprehensive search of major biomedical databases including MEDLINE, EMBASE, ClNAHL, PsycINFO and the Cochrane Library was conducted. Specialist complementary and alternative medicine databases were searched and efforts were made to identify unpublished and ongoing research. Citations were included from the databases' inception to March 2005. Randomized controlled trials (RCTs) were appraised and meta-analysis undertaken. Clinical commentaries were obtained. Six RCTs evaluating the effectiveness of hypnosis in CINV were found. In five of these studies the participants were children. Studies report positive results including statistically significant reductions in anticipatory and CINV. Meta-analysis revealed a large effect size of hypnotic treatment when compared with treatment as usual, and the effect was at least as large as that of cognitive-behavioural therapy. Meta-analysis has demonstrated that hypnosis could be a clinically valuable intervention for anticipatory and CINV in children with cancer. Further research into the effectiveness, acceptance and feasibility of hypnosis in CINV, particularly in adults, is suggested. Future studies should assess suggestibility and provide full details of the hypnotic intervention.

You Cannot Step Into the Same River Twice: When Power Analyses Are Optimistic.

PubMed

McShane, Blakeley B; Böckenholt, Ulf

2014-11-01

Statistical power depends on the size of the effect of interest. However, effect sizes are rarely fixed in psychological research: Study design choices, such as the operationalization of the dependent variable or the treatment manipulation, the social context, the subject pool, or the time of day, typically cause systematic variation in the effect size. Ignoring this between-study variation, as standard power formulae do, results in assessments of power that are too optimistic. Consequently, when researchers attempting replication set sample sizes using these formulae, their studies will be underpowered and will thus fail at a greater than expected rate. We illustrate this with both hypothetical examples and data on several well-studied phenomena in psychology. We provide formulae that account for between-study variation and suggest that researchers set sample sizes with respect to our generally more conservative formulae. Our formulae generalize to settings in which there are multiple effects of interest. We also introduce an easy-to-use website that implements our approach to setting sample sizes. Finally, we conclude with recommendations for quantifying between-study variation. © The Author(s) 2014.

Social Network Sites as a Mode to Collect Health Data: A Systematic Review

PubMed Central

Ramzan, Farzan; Rawaf, Salman; Majeed, Azeem

2014-01-01

Background To date, health research literature has focused on social network sites (SNS) either as tools to deliver health care, to study the effect of these networks on behavior, or to analyze Web health content. Less is known about the effectiveness of these sites as a method for collecting data for health research and the means to use such powerful tools in health research. Objective The objective of this study was to systematically review the available literature and explore the use of SNS as a mode of collecting data for health research. The review aims to answer four questions: Does health research employ SNS as method for collecting data? Is data quality affected by the mode of data collection? What types of participants were reached by SNS? What are the strengths and limitations of SNS? Methods The literature was reviewed systematically in March 2013 by searching the databases MEDLINE, Embase, and PsycINFO, using the Ovid and PubMed interface from 1996 to the third week of March 2013. The search results were examined by 2 reviewers, and exclusion, inclusion, and quality assessment were carried out based on a pre-set protocol. Results The inclusion criteria were met by 10 studies and results were analyzed descriptively to answer the review questions. There were four main results. (1) SNS have been used as a data collection tool by health researchers; all but 1 of the included studies were cross-sectional and quantitative. (2) Data quality indicators that were reported include response rate, cost, timeliness, missing data/completion rate, and validity. However, comparison was carried out only for response rate and cost as it was unclear how other reported indicators were measured. (3) The most targeted population were females and younger people. (4) All studies stated that SNS is an effective recruitment method but that it may introduce a sampling bias. Conclusions SNS has a role in health research, but we need to ascertain how to use it effectively without affecting the quality of research. The field of SNS is growing rapidly, and it is necessary to take advantage of the strengths of this tool and to avoid its limitations by effective research design. This review provides an important insight for scholars who plan to conduct research using SNS. PMID:25048247

Comparative effectiveness research in hand surgery.

PubMed

Johnson, Shepard P; Chung, Kevin C

2014-08-01

Comparative effectiveness research (CER) is a concept initiated by the Institute of Medicine and financially supported by the federal government. The primary objective of CER is to improve decision making in medicine. This research is intended to evaluate the effectiveness, benefits, and harmful effects of alternative interventions. CER studies are commonly large, simple, observational, and conducted using electronic databases. To date, there is little comparative effectiveness evidence within hand surgery to guide therapeutic decisions. To draw conclusions on effectiveness through electronic health records, databases must contain clinical information and outcomes relevant to hand surgery interventions, such as patient-related outcomes.

Background: Characterization of the epigenome is a primary interest for children’s environmental health researchers studying the environmental influences on human populations, particularly those studying the role of pregnancy and early-life exposures on later-in-life health outcomes. Objectives: Our objective was to consider the state of the science in environmental epigenetics research and to focus on DNA methylation and the collective observations of many studies being conducted within the Children’s Environmental Health and Disease Prevention Research Centers, as they relate to the Developmental Origins of Health and Disease (DOHaD) hypothesis. Methods: We address the current laboratory and statistical tools available for epigenetic analyses, discuss methods for validation and interpretation of findings, particularly when magnitudes of effect are small, question the functional relevance of findings, and discuss the future for environmental epigenetics research. Discussion: A common finding in environmental epigenetic studies is the small-magnitude epigenetic effect sizes that result from such exposures. Although it is reasonable and necessary that we question the relevance of such small effects, we present examples in which small effects persist and have been replicated across populations and across time. We encourage a critical discourse on the interpretation of such small changes and further research on their functional relevance for children’s health. Conclusion: The dynamic nature of the epigenome will require an emphasis on future longitudinal studies in which the epigenome is profiled over time, over changing environmental exposures, and over generations to better understand the multiple ways in which the epigenome may respond to environmental stimuli.

Clinical outcomes research seeks to understand the real-world manifestations of clinical care. In particular, outcomes research seeks to reveal the effects of pharmaceutical, procedural, and structural aspects of healthcare on patient outcomes, including mortality, disease control, toxicity, cost, and quality of life. Although outcomes research can utilize interventional study designs, insightful use of observational data is a defining feature of this field. Many questions in gynecologic oncology are not amenable to investigation in randomized clinical trials due to cost, feasibility, or ethical concerns. When a randomized trial is not practical or has not yet been conducted, well-designed observational studies have the potential to provide the best available evidence about the effects of clinical care. Such studies may use surveys, medical records, disease registries, and a variety of administrative data sources. Even when a randomized trial has been conducted, observational studies can be used to estimate the real-world effect of an intervention, which may differ from the results obtained in the controlled setting of a clinical trial. This article reviews the goals, methodologies, data sources, and limitations of clinical outcomes research, with a focus on gynecologic oncology. Copyright © 2017. Published by Elsevier Inc.

Strategies to assist evidence-based decision-making for healthcare professionals are crucial to ensure high quality patient care and outcomes. The goal of this systematic review was to identify and synthesize the evidence on knowledge translation interventions aimed at putting explicit research evidence into child health practice. A comprehensive search of thirteen electronic databases was conducted, restricted by date (1985-2011) and language (English). Articles were included if: 1) studies were randomized controlled trials (RCT), controlled clinical trials (CCT), or controlled before-and-after (CBA) studies; 2) target population was child health professionals; 3) interventions implemented research in child health practice; and 4) outcomes were measured at the professional/process, patient, or economic level. Two reviewers independently extracted data and assessed methodological quality. Study data were aggregated and analyzed using evidence tables. Twenty-one studies (13 RCT, 2 CCT, 6 CBA) were included. The studies employed single (n=9) and multiple interventions (n=12). The methodological quality of the included studies was largely moderate (n=8) or weak (n=11). Of the studies with moderate to strong methodological quality ratings, three demonstrated consistent, positive effect(s) on the primary outcome(s); effective knowledge translation interventions were two single, non-educational interventions and one multiple, educational intervention. This multidisciplinary systematic review in child health setting identified effective knowledge translation strategies assessed by the most rigorous research designs. Given the overall poor quality of the research literature, specific recommendations were made to improve knowledge translation efforts in child health. Copyright © 2016 Elsevier Inc.

Abstract A course-based undergraduate research experience (CURE) spanning three semesters was introduced into freshman and sophomore biology classes, with the hypothesis that participation in a CURE affects skills in research, communication, and collaboration, which may help students persist in science. Student research projects were centered on the hypothesis that nicotine and caffeine exposure during early development affects gastrulation and heart development in zebrafish. First, freshmen generated original data showing distinct effects of embryonic nicotine and caffeine exposure on zebrafish heart development and function. Next, Cell Biology laboratory students continued the CURE studies and identified novel teratogenic effects of nicotine and caffeine during gastrulation. Finally, new freshmen continued the CURE research, examining additional toxicant effects on development. Students designed new protocols, made measurements, presented results, and generated high-quality preliminary data that were studied in successive semesters. By implementing this project, the CURE extended faculty research and provided a scalable model to address national goals to involve more undergraduates in authentic scientific research. In addition, student survey results support the hypothesis that CUREs provide significant gains in student ability to (1) design experiments, (2) analyze data, and (3) make scientific presentations, translating into high student satisfaction and enhanced learning.

Effects of psycho-behavioral interventions on immune functioning in cancer patients: a systematic review.

PubMed

Tong, Guixian; Geng, Qingqing; Cheng, Jing; Chai, Jing; Xia, Yi; Feng, Rui; Zhang, Lu; Wang, Debin

2014-01-01

This study aimed at summarizing evidence about effects of psycho-behavioral interventions (PBIs) on immune responses among cancer patients and analyzing quality of published studies so as to inform future researches. Literature retrieval utilized both highly inclusive algorithms searching randomized controlled studies published in English and Chinese and manual searching of eligible studies from references of relevant review papers. Two researchers examined the articles selected separately and extracted the information using a pre-designed form for soliciting data about the trials (e.g., sample size, disease status, intervention, immune responses) and quality ratings of the studies. Both narrative descriptions and meta-analysis (via Review manager 5) were used synthesizing the effects of PBIs on immune responses among cancer patients and state of art of the researches in this area. Seventy-six RCTs met inclusion criteria. PBIs implemented were divided into three major categories including psychological state adjustment, physical activity and dietary modification. Immune indicators measured included CD4+ cells, CD8+ cells, CD4/CDC8+ ratio, CD3+ cells, NK cell activity, etc. Effects of PBIs on immune responses documented in individual papers were mixed and pooled analysis of CD4+ cells, CD4+/CD8+ ratio, CD3+ cells, NKCA, IgG, IgM and IL-2 showed modest effects. However, there were huge discrepancies in intervention effects between studies published in English and Chinese and the results should be interpreted with caution. Besides, most studies suffer from some quality flaws concerning blinding, randomization procedures, compliance, attrition and intention-to-treat analyses, etc. Although there are considerable evidences of PBI effects on some immune indicators, the effect sizes are modest and it is still premature to conclude whether PBIs have effects on immune functions among cancer patients. There is a clear need for much more rigorous efforts in this area and future researches should pay particular attention to intervention dose and focus, sample size and comparable immune measures.

Informed consent in human research: what to say and how to say it.

PubMed

Reiman, Robert E

2013-02-01

To ensure that the possibility of harm to human research subjects is minimized, clinical trials and other research protocols are subject to oversight by Institutional Review Boards (IRBs). IRBs require that subjects be fully informed about the real or potential risks of participation in a research study. The use of radiological examinations in research protocols subjects the participants to exposure to ionizing radiation, which in theory carries a risk of stochastic effects such as radiation-induced cancer, and in practice may lead to deterministic effects such as skin injury. Because IRB members and clinical study coordinators may have little knowledge of radiation effects or how best to communicate the risk to the research subjects, they will consult with institutional Radiation Safety Committees and radiation protection professionals regarding how to integrate radiation risk information into the informed consent process. Elements of radiation informed consent include: (1) comparison of the radiation dose to some benchmark that enables the study subjects to make a value judgment regarding the acceptability of the risk; (2) a quantitative expression of the absolute risk of stochastic effects; (3) an expression of uncertainty in the risk; and (4) understandability. Standardized risk statement templates may be created for specific radiological examinations. These standardized risk statements may be deployed as paper forms or electronically in the form of internet-based applications. The technical nature of creating useful radiation risk statements represents an opportunity for radiation protection professionals to participate productively in the clinical research process.

An integrated approach for analysing earthquake-induced surface effects: A case study from the Northern Apennines, Italy

NASA Astrophysics Data System (ADS)

Castaldini, D.; Genevois, R.; Panizza, M.; Puccinelli, A.; Berti, M.; Simoni, A.

This paper illustrates research addressing the subject of the earthquake-induced surface effects by means of a multidisciplinary approach: tectonics, neotectonics, seismology, geology, hydrogeology, geomorphology, soil/rock mechanics have been considered. The research is aimed to verify in areas affected by earthquake-triggered landslides a methodology for the identification of potentially unstable areas. The research was organized according to regional and local scale studies. In order to better emphasise the complexity of the relationships between all the parameters affecting the stability conditions of rock slopes in static and dynamic conditions a new integrated approach, Rock Engineering Systems (RES), was applied in the Northern Apennines. In the paper, the different phases of the research are described in detail and an example of the application of RES method in a sample area is reported. A significant aspect of the study can be seen in its attempt to overcome the exclusively qualitative aspects of research into the relationship between earthquakes and induced surface effects, and to advance the idea of beginning a process by which this interaction can be quantified.

Participatory action research (PAR) methodology is an effective tool in identifying and implementing risk-reduction interventions. It has been used extensively in occupational health research, but not, to our knowledge, in disaster research. A PAR framework was incorporated into the World Trade Center evacuation study, which was designed to identify the individual, organizational, and structural (environmental) factors that affected evacuation from the World Trade Center Towers 1 and 2 on September 11, 2001. PAR teams-comprising World Trade Center evacuees, study investigators, and expert consultants-worked collaboratively to develop a set of recommendations designed to facilitate evacuation from high-rise office buildings and reduce risk of injury among evacuees. Two PAR teams worked first separately and then collectively to identify data-driven strategies for improvement of high-rise building evacuation. The teams identified interventions targeting individual, organizational, and structural (environmental) barriers to safe and rapid evacuation. PAR teams were effective in identifying numerous feasible and cost-effective strategies for improvement of high-rise emergency preparedness and evacuation. This approach may have utility in other workplace disaster prevention planning and response programs.

Practice-Based Knowledge Discovery for Comparative Effectiveness Research: An Organizing Framework

Lucero, Robert J.; Bakken, Suzanne

2014-01-01

Electronic health information systems can increase the ability of health-care organizations to investigate the effects of clinical interventions. The authors present an organizing framework that integrates outcomes and informatics research paradigms to guide knowledge discovery in electronic clinical databases. They illustrate its application using the example of hospital acquired pressure ulcers (HAPU). The Knowledge Discovery through Informatics for Comparative Effectiveness Research (KDI-CER) framework was conceived as a heuristic to conceptualize study designs and address potential methodological limitations imposed by using a single research perspective. Advances in informatics research can play a complementary role in advancing the field of outcomes research including CER. The KDI-CER framework can be used to facilitate knowledge discovery from routinely collected electronic clinical data. PMID:25278645

Instrumental variable methods in comparative safety and effectiveness research†

Brookhart, M. Alan; Rassen, Jeremy A.; Schneeweiss, Sebastian

2010-01-01

Summary Instrumental variable (IV) methods have been proposed as a potential approach to the common problem of uncontrolled confounding in comparative studies of medical interventions, but IV methods are unfamiliar to many researchers. The goal of this article is to provide a non-technical, practical introduction to IV methods for comparative safety and effectiveness research. We outline the principles and basic assumptions necessary for valid IV estimation, discuss how to interpret the results of an IV study, provide a review of instruments that have been used in comparative effectiveness research, and suggest some minimal reporting standards for an IV analysis. Finally, we offer our perspective of the role of IV estimation vis-à-vis more traditional approaches based on statistical modeling of the exposure or outcome. We anticipate that IV methods will be often underpowered for drug safety studies of very rare outcomes, but may be potentially useful in studies of intended effects where uncontrolled confounding may be substantial.

Philipson, Tomas; Linthicum, Mark T; Snider, Julia Thornton

2014-11-01

As healthcare costs climb around the world, public and private payers alike are demanding evidence of a treatment's value to support approval and reimbursement decisions. Health economics and outcomes research, or HEOR, offers tools to answer questions about a treatment's value, as well as its real-world effects and cost-effectiveness. Given that nutrition interventions have to compete for space in budgets along with biopharmaceutical products and devices, nutrition is now increasingly coming to be evaluated through HEOR. This tutorial introduces the discipline of HEOR and motivates its relevance for nutrition. We first define HEOR and explain its role and relevance in relation to randomized controlled trials. Common HEOR study types--including burden of illness, effectiveness studies, cost-effectiveness analysis, and valuation studies--are presented, with applications to nutrition. Tips for critically reading HEOR studies are provided, along with suggestions on how to use HEOR to improve patient care. Directions for future research are discussed. © 2014 Abbott Nutrition.

Harding, Katherine; Lynch, Lauren; Porter, Judi; Taylor, Nicholas F

2017-03-01

Objective The aim of the present study was to determine whether there is an association between having research culture in a health service and better organisational performance. Methods Using systematic review methods, databases were searched, inclusion criteria applied and study quality appraised. Data were extracted from selected studies and the results were synthesised descriptively. Results Eight studies were selected for review. Five studies compared health services with high versus low levels of research activity among the workforce. Three studies evaluated the effect of specific interventions focused on the health workforce. All studies reported a positive association between research activity and organisational performance. Improved organisational performance included lower patient mortality rates (two of two studies), higher levels of patient satisfaction (one of one study), reduced staff turnover (two of two studies), improved staff satisfaction (one of two studies) and improved organisational efficiency (four of five studies). Conclusions A stronger research culture appears to be associated with benefits to patients, staff and the organisation. What is known about this topic? Research investment in the health workforce can increase research productivity of the health workforce. In addition, investment in clinical research can lead to positive health outcomes. However, it is not known whether a positive research culture among the health workforce is associated with improved organisational performance. What does this paper add? The present systematic review of the literature provides evidence that a positive research culture and interventions directed at the health workforce are associated with patient, staff and organisational benefits. What are the implications for practitioners? For health service managers and policy makers, one interpretation of the results could be to provide support for initiatives directed at the health workforce to increase a research culture in health services. However, because association does not imply causation, managers need to interpret the results with caution and evaluate the effect of any initiatives to increase the research culture of the health workforce on the performance of their organisation.

2011-03-01

Cultural competency training has been proposed as a way to improve patient outcomes. There is a need for evidence showing that these interventions reduce health disparities. The objective was to conduct a systematic review addressing the effects of cultural competency training on patient-centered outcomes; assess quality of studies and strength of effect; and propose a framework for future research. The authors performed electronic searches in the MEDLINE/PubMed, ERIC, PsycINFO, CINAHL and Web of Science databases for original articles published in English between 1990 and 2010, and a bibliographic hand search. Studies that reported cultural competence educational interventions for health professionals and measured impact on patients and/or health care utilization as primary or secondary outcomes were included. Four authors independently rated studies for quality using validated criteria and assessed the training effect on patient outcomes. Due to study heterogeneity, data were not pooled; instead, qualitative synthesis and analysis were conducted. Seven studies met inclusion criteria. Three involved physicians, two involved mental health professionals and two involved multiple health professionals and students. Two were quasi-randomized, two were cluster randomized, and three were pre/post field studies. Study quality was low to moderate with none of high quality; most studies did not adequately control for potentially confounding variables. Effect size ranged from no effect to moderately beneficial (unable to assess in two studies). Three studies reported positive (beneficial) effects; none demonstrated a negative (harmful) effect. There is limited research showing a positive relationship between cultural competency training and improved patient outcomes, but there remains a paucity of high quality research. Future work should address challenges limiting quality. We propose an algorithm to guide educators in designing and evaluating curricula, to rigorously demonstrate the impact on patient outcomes and health disparities.

Psychological Treatment of Sexual Offenders Against Children: A Meta-Analytic Review of Treatment Outcome Studies.

PubMed

Grønnerød, Cato; Grønnerød, Jarna Soilevuo; Grøndahl, Pål

2015-07-01

Numerous meta-analyses and reviews have been conducted on the effectiveness of psychological treatment of sexual offenders in reducing recidivism, but no meta-analysis has been done on sexual offenders against children (SOAC) specifically. A moderate treatment effect has been shown in several evaluations of general sexual offenders, while many scholars maintain that the question remains unanswered until an adequate number of effectiveness studies with a strong research design have been carried out. In this meta-analysis, we evaluated 14 studies selected and coded according to Collaborative Outcome Data Committee (CODC) criteria. They included 1,421 adult offenders in psychotherapy and 1,509 nontreated controls, with a minimum average follow-up period of 3 years, published in peer-reviewed journals in 1980 or later. Recidivism was defined as rearrest or reconviction. Study quality was classified into strong, good, weak or rejected. The analysis revealed a treatment effect size of r = .03 for nine studies evaluated as Good or Weak, while all studies yielded an effect size of r = .08, including five studies classified as Rejected. The results show that the available research cannot establish any effect of treatment on SOAC. Despite a large amount of research, only a tiny fraction of studies meet a minimum of scientific standards, and even fewer provide sensible and useful data from which it is possible to draw conclusions. © The Author(s) 2014.

The effectiveness of ethics education: a quasi-experimental field study.

PubMed

May, Douglas R; Luth, Matthew T

2013-06-01

Ethical conduct is the hallmark of excellence in engineering and scientific research, design, and practice. While undergraduate and graduate programs in these areas routinely emphasize ethical conduct, few receive formal ethics training as part of their curricula. The first purpose of this research study was to assess the relative effectiveness of ethics education in enhancing individuals' general knowledge of the responsible conduct of research practices and their level of moral reasoning. Secondly, we examined the effects of ethics education on the positive psychological outcomes of perspective-taking, moral efficacy, moral courage, and moral meaningfulness. To examine our research hypotheses, we utilized a pretest-posttest quasi-experimental design consisting of three ethics education groups (control, embedded modules, and stand-alone courses). Findings revealed that both embedded and stand alone courses were effective in enhancing participants' perspective-taking, moral efficacy, and moral courage. Moral meaningfulness was marginally enhanced for the embedded module condition. Moral judgment and knowledge of responsible conduct of research practices were not influenced by either ethics education condition. Contrary to expectations, stand alone courses were not superior to embedded modules in influencing the positive psychological outcomes investigated. Implications of these findings for future research and practice are discussed.

Schommer, Jon C; Hansen, Richard A

2005-06-01

The objectives of this article are to (1) identify key methodological issues related to investigating the effects of direct-to-consumer advertising (DTCA) for prescription drugs, (2) highlight opportunities and challenges that these issues pose, and (3) provide suggestions to address these challenges and opportunities from a social and administrative pharmacy perspective. Through a review of existing literature and consultation with research colleagues, we identified 3 broad issues regarding the study of DTCA for prescription drugs: (1) the importance of problem formulation, (2) the role of health behavior and decision-making perspectives, and (3) data collection and data analysis challenges and opportunities. Based upon our findings, we developed recommendations for future research in this area. Clear problem formulation will be instructive for prioritizing research needs and for determining the role that health behavior and decision-making perspectives can serve in DTCA research. In addition, it appears that cluster bias, nonlinear relationships, mediating/moderating effects, time effects, acquiescent response, and case mix are particularly salient challenges for the DTCA research domain. We suggest that problem formulation, selection of sound theories upon which to base research, and data collection and data analysis challenges are key methodological issues related to investigating the effects of DTCA for prescription drugs.

The United States lacks a system to use routinely collected electronic health record (EHR) clinical data to conduct comparative effectiveness research (CER) on pediatric drug therapeutics and other child health topics. This Special Article describes the creation and details of a network of EHR networks devised to use clinical data in EHRs for conducting CER, led by the American Academy of Pediatrics Pediatric Research in Office Settings (PROS). To achieve this goal, PROS has linked data from its own EHR-based "ePROS" network with data from independent practices and health systems across the United States. Beginning with 4 of proof-of-concept retrospective CER studies on psychotropic and asthma medication use and side effects with a planned full-scale prospective CER study on treatment of pediatric hypertension, the Comparative Effectiveness Research Through Collaborative Electronic Reporting (CER(2)) collaborators are developing a platform to advance the methodology of pediatric pharmacoepidemiology. CER(2) will provide a resource for future CER studies in pediatric drug therapeutics and other child health topics. This article outlines the vision for and present composition of this network, governance, and challenges and opportunities for using the network to advance child health and health care. The goal of this network is to engage child health researchers from around the United States in participating in collaborative research using the CER(2) database.

Aggregate and individual replication probability within an explicit model of the research process.

PubMed

Miller, Jeff; Schwarz, Wolf

2011-09-01

We study a model of the research process in which the true effect size, the replication jitter due to changes in experimental procedure, and the statistical error of effect size measurement are all normally distributed random variables. Within this model, we analyze the probability of successfully replicating an initial experimental result by obtaining either a statistically significant result in the same direction or any effect in that direction. We analyze both the probability of successfully replicating a particular experimental effect (i.e., the individual replication probability) and the average probability of successful replication across different studies within some research context (i.e., the aggregate replication probability), and we identify the conditions under which the latter can be approximated using the formulas of Killeen (2005a, 2007). We show how both of these probabilities depend on parameters of the research context that would rarely be known in practice. In addition, we show that the statistical uncertainty associated with the size of an initial observed effect would often prevent accurate estimation of the desired individual replication probability even if these research context parameters were known exactly. We conclude that accurate estimates of replication probability are generally unattainable.

The pediatric rheumatic diseases are a heterogeneous group of rare diseases, posing a number of challenges for the use of traditional clinical and translational research methods. Innovative comparative effectiveness approaches are needed to efficiently study treatment strategies and disease outcomes. The Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed the consensus treatment plan (CTP) approach as a comparative effectiveness tool for research in pediatric rheumatology. CTPs are treatment strategies, developed by consensus methods among CARRA members, intended to reduce variation in treatment approaches, standardize outcome measurements, and allow for comparison of the effectiveness of different approaches with the goal of improving disease outcomes. To date, CTPs have been published for 8 different diseases and disease manifestations. The approach has been successfully piloted for juvenile localized scleroderma, systemic juvenile idiopathic arthritis (JIA), polyarticular JIA, dermatomyositis, and lupus nephritis. Large-scale studies are underway for systemic JIA and polyarticular JIA, with the CARRA patient registry serving as the data collection platform. These studies have been designed with stakeholder involvement, including active input from CARRA providers, patients, and parents, with the goal of increasing feasibility and ensuring the relevance of the outcomes. These studies include ancillary biologic specimen collection intended to support additional translational and mechanistic studies. Data from these ongoing CTP studies will provide more information on the ability of this approach to identify effective treatment strategies and improve outcomes in the pediatric rheumatic diseases. © 2018, American College of Rheumatology.

Accelerating Translation of Physical Activity and Cancer Survivorship Research into Practice: Recommendations for a More Integrated and Collaborative Approach

PubMed Central

Phillips, Siobhan M.; Alfano, Catherine M.; Perna, Frank M.; Glasgow, Russell E.

2015-01-01

Physical activity has been deemed safe and effective in reducing many negative side effects of treatment for cancer survivors and promoting better overall health. However, most of this research has focused on highly controlled randomized trials and little of this research has been translated into care or policy for survivors. The purpose of the present paper is to present a research agenda for the field to accelerate the dissemination and implementation of empirically-supported physical activity interventions into care. We provide rationale for the role of basic, behavioral, clinical implementation and population scientists in moving this science forward and call for a more coordinated effort across different phases of research. In addition, we provide key strategies and examples for ongoing and future studies using the RE-AIM (Reach, Efficacy/Effectiveness, Adoption, Implementation and Maintenance) framework and pose recommendations for collaborations between researchers and stakeholders to enhance the integration of this research into policy and practice. Overall, we recommend that physical activity and cancer survivorship research employ additional study designs, include relevant stakeholders and be more collaborative, integrated, contextual, and representative in terms of both setting and participants.

Setting a research question, aim and objective.

PubMed

Doody, Owen; Bailey, Maria E

2016-03-01

To describe the development of a research question, aim and objective. The first steps of any study are developing the research question, aim and objective. Subsequent steps develop from these and they govern the researchers' choice of population, setting, data to be collected and time period for the study. Clear, succinctly posed research questions, aims and objectives are essential if studies are to be successful. Researchers developing their research questions, aims and objectives generally experience difficulties. They are often overwhelmed trying to convert what they see as a relevant issue from practice into research. This necessitates engaging with the relevant published literature and knowledgeable people. This paper identifies the issues to be considered when developing a research question, aim and objective. Understanding these considerations will enable researchers to effectively present their research question, aim and objective. To conduct successful studies, researchers should develop clear research questions, aims and objectives.

An hourly variation in zoo visitor interest: measurement and significance for animal welfare research.

PubMed

Davey, Gareth

2006-01-01

A methodological difficulty facing welfare research on nonhuman animals in the zoo is the large number of uncontrolled variables due to variation within and between study sites. Zoo visitors act as uncontrolled variables, with number, density, size, and behavior constantly changing. This is worrisome because previous research linked visitor variables to animal behavioral changes indicative of stress. There are implications for research design: Studies not accounting for visitors' effect on animal welfare risk confounding (visitor) variables distorting their findings. Zoos need methods to measure and minimize effects of visitor behavior and to ensure that there are no hidden variables in research models. This article identifies a previously unreported variable--hourly variation (decrease) in visitor interest--that may impinge on animal welfare and validates a methodology for measuring it. That visitor interest wanes across the course of the day has important implications for animal welfare management; visitor effects on animal welfare are likely to occur, or intensify, during the morning or in earlier visits when visitor interest is greatest. This article discusses this issue and possible solutions to reduce visitor effects on animal well-being.

Correlational effect size benchmarks.

PubMed

Bosco, Frank A; Aguinis, Herman; Singh, Kulraj; Field, James G; Pierce, Charles A

2015-03-01

Effect size information is essential for the scientific enterprise and plays an increasingly central role in the scientific process. We extracted 147,328 correlations and developed a hierarchical taxonomy of variables reported in Journal of Applied Psychology and Personnel Psychology from 1980 to 2010 to produce empirical effect size benchmarks at the omnibus level, for 20 common research domains, and for an even finer grained level of generality. Results indicate that the usual interpretation and classification of effect sizes as small, medium, and large bear almost no resemblance to findings in the field, because distributions of effect sizes exhibit tertile partitions at values approximately one-half to one-third those intuited by Cohen (1988). Our results offer information that can be used for research planning and design purposes, such as producing better informed non-nil hypotheses and estimating statistical power and planning sample size accordingly. We also offer information useful for understanding the relative importance of the effect sizes found in a particular study in relationship to others and which research domains have advanced more or less, given that larger effect sizes indicate a better understanding of a phenomenon. Also, our study offers information about research domains for which the investigation of moderating effects may be more fruitful and provide information that is likely to facilitate the implementation of Bayesian analysis. Finally, our study offers information that practitioners can use to evaluate the relative effectiveness of various types of interventions. PsycINFO Database Record (c) 2015 APA, all rights reserved.

2015-10-01

Nurse scientists are increasingly recognizing the necessity of conducting research with community groups to effectively address complex health problems and successfully translate scientific advancements into the community. Although several barriers to conducting research with community groups exist, community-based participatory research (CBPR) has the potential to mitigate these barriers. CBPR has been employed in programs of research that respond in culturally sensitive ways to identify community needs and thereby address current health disparities. This article presents case studies that demonstrate how CBPR principles guided the development of (a) a healthy body weight program for urban, underserved African American women; (b) a reproductive health educational intervention for urban, low-income, underserved, ethnically diverse women; and (c) a pilot anxiety/depression intervention for urban, low-income, underserved, ethnically diverse women. These case studies illustrate the potential of CBPR as an orientation to research that can be employed effectively in non-research-intensive academic environments. © The Author(s) 2015.

The authors have been researching the promotion of lactic acid fermentation by ultrasonic irradiation. In the past research, it was proven that ultrasonic irradiation is effective in the process of fermentation, and the production of yoghurt and kefir was promoted. In this study, the effect of the ultrasonic frequency in this fermentation process was examined. In the frequency range of this study, it was found that the action of fermentation promotion was exponentially proportionate to the irradiated ultrasonic frequency.

Few studies examining the cognitive effects of chronic cannabis use utilize research designs where examiners are blind to user status. Even in those that do, researchers may be able to guess the user status of participants, leaving these studies vulnerable to the expectancy effect confound. The present study examined the ability of neuropsychologists (those who would conduct research on the cognitive effects of cannabis) to differentiate cannabis users and nonusers based on physical appearance from photographs. We recruited 84 participants from an international neuropsychology listserv. The sample was 59.5% female and 95.2% Caucasian, with a mean age of 41.39 years (range 26-65). Each neuropsychologist rated 25 target faces (12 cannabis users, 13 nonusers) on a Marijuana Use Likelihood Index based upon individuals' photographs. Results indicate a main effect of user group, as neuropsychologists ascribed higher ratings to cannabis users on the Marijuana Use Likelihood Index, suggesting they perceive them as more likely to be users, relative to nonusers. Results also demonstrated a main effect of gender, as males received higher user ratings than females, and a significant main effect of rater gender, as female raters were more likely to rate individuals as cannabis users relative to male raters. Conclusions/Importance: The results demonstrate the importance of assessing researchers' expectations when studying the effects of chronic cannabis use, as even those designs that keep examiners blind to participant user status may be vulnerable to expectancy effects if examiners are able to guess user status based upon appearance alone.

2014-07-01

Assessing relative performance among competing interventions is an important part of comparative effectiveness research. Bayesian indirect comparisons add information to existing Cochrane reviews, such as which intervention is likely to perform best. However, heterogeneity variance priors may influence results and, potentially, clinical guidance. We highlight the features of Bayesian indirect comparisons using a case study of a Cochrane review update in asthma care. The probability that one self-management educational intervention outperforms others is estimated. Simulation studies investigate the effect of heterogeneity variance prior distributions. Results suggest a 55% probability that individual education is best, followed by combination (39%) and group (6%). The intervention with few trials was sensitive to prior distributions. Bayesian indirect comparisons updates of Cochrane reviews are valuable comparative effectiveness research tools.

This special issue focuses on challenges and solutions to implementing effective reading intervention in schools in the United States. Researchers often develop interventions that prove effective in efficacy studies but then show no impact when implemented at scale in public school settings. The authors of the intervention studies presented here describe a number of common implementation problems stemming from research in primary grades, middle grades, and high schools. Solutions to these implementation problems include establishing researcher-practitioner partnerships to address the systems-level challenges, suggestions for how to obtain buy-in from teachers, and recommendations for reforming preservice and in-service teacher education. © 2016 Wiley Periodicals, Inc.

Methodological Characteristics and Future Directions for Plyometric Jump Training Research: A Scoping Review.

Recently, there has been a proliferation of published articles on the effect of plyometric jump training, including several review articles and meta-analyses. However, these types of research articles are generally of narrow scope. Furthermore, methodological limitations among studies (e.g., a lack of active/passive control groups) prevent the generalization of results, and these factors need to be addressed by researchers. On that basis, the aims of this scoping review were to (1) characterize the main elements of plyometric jump training studies (e.g., training protocols) and (2) provide future directions for research. From 648 potentially relevant articles, 242 were eligible for inclusion in this review. The main issues identified related to an insufficient number of studies conducted in females, youths, and individual sports (~ 24.0, ~ 37.0, and ~ 12.0% of overall studies, respectively); insufficient reporting of effect size values and training prescription (~ 34.0 and ~ 55.0% of overall studies, respectively); and studies missing an active/passive control group and randomization (~ 40.0 and ~ 20.0% of overall studies, respectively). Furthermore, plyometric jump training was often combined with other training methods and added to participants' daily training routines (~ 47.0 and ~ 39.0% of overall studies, respectively), thus distorting conclusions on its independent effects. Additionally, most studies lasted no longer than 7 weeks. In future, researchers are advised to conduct plyometric training studies of high methodological quality (e.g., randomized controlled trials). More research is needed in females, youth, and individual sports. Finally, the identification of specific dose-response relationships following plyometric training is needed to specifically tailor intervention programs, particularly in the long term.

Research for the jamming mechanism of high-frequency laser to the laser seeker

High-frequency laser will be able to enter the enemy laser signal processing systems without encoded identification and a copy. That makes it one of the research directions of new interference sources. In order to study the interference mechanism of high-frequency laser to laser guided weapons. According to the principle of high-frequency laser interference, a series of related theoretical models such as a semi-active laser seeker coded identification model, a time door model, multi-signal processing model and a interference signal modulation processing model are established. Then seeker interfere with effective 3σ criterion is proposed. Based on this, the study of the effect of multi-source interference and signal characteristics of the effect of high repetition frequency laser interference are key research. According to the simulation system testing, the results show that the multi-source interference and interference signal frequency modulation can effectively enhance the interference effect. While the interference effect of the interference signal amplitude modulation is not obvious. The research results will provide the evaluation of high-frequency laser interference effect and provide theoretical references for high-frequency laser interference system application.

2014-01-01

Objective Multilevel models have become a standard data analysis approach in intervention research. Although the vast majority of intervention studies involve multiple outcome measures, few studies use multivariate analysis methods. The authors discuss multivariate extensions to the multilevel model that can be used by psychotherapy researchers. Method and Results Using simulated longitudinal treatment data, the authors show how multivariate models extend common univariate growth models and how the multivariate model can be used to examine multivariate hypotheses involving fixed effects (e.g., does the size of the treatment effect differ across outcomes?) and random effects (e.g., is change in one outcome related to change in the other?). An online supplemental appendix provides annotated computer code and simulated example data for implementing a multivariate model. Conclusions Multivariate multilevel models are flexible, powerful models that can enhance clinical research. PMID:24491071

2013-01-01

Comparative effectiveness research (CER) is a scientific method of investigating the effectiveness of alternative intervention methods. In a CER study, clinical researchers typically start with a CER hypothesis, and aim to evaluate it by applying a series of medical statistical methods. Traditionally, the CER hypotheses are defined manually by clinical researchers. This makes the task of hypothesis generation very time-consuming and the quality of hypothesis heavily dependent on the researchers' skills. Recently, with more electronic medical data being collected, it is highly promising to apply the computerized method for discovering CER hypotheses from clinical data sets. In this poster, we proposes a novel approach to automatically generating CER hypotheses based on mining clinical data, and presents a case study showing that the approach can facilitate clinical researchers to identify potentially valuable hypotheses and eventually define high quality CER studies.

A Critical Review of the Effects of Nicotine and Alcohol Coadministration in Human Laboratory Studies.

PubMed

Dermody, Sarah S; Hendershot, Christian S

2017-03-01

Simultaneous use of cigarettes and alcohol is common and may be driven by nicotine increasing alcohol self-administration or vice versa. To better evaluate the causal nature of this relationship, we systematically reviewed human experimental laboratory studies that coadministered nicotine and alcohol with control conditions. Searches of PubMed/MEDLINE and PsycINFO databases and study bibliographies identified 30 studies that met our inclusion criteria. Research methodologies were critically reviewed. Effects of coadministration on drug self-administration and related factors such as craving, subjective response, motivation, and heart rate are reported. Results most strongly supported that alcohol increases nicotine and cigarette self-administration, whereas, depending on the context, nicotine increased, decreased, or had no effect on alcohol self-administration. Craving and subjective drug effects were also impacted by coadministration. Interaction effects of nicotine and alcohol on self-administration and subjective responses were reported infrequently. The effects may be moderated by a number of factors, including dose of administered drug and sex. Recommendations are made for future research, and clinical and policy implications of findings are discussed. Copyright © 2017 by the Research Society on Alcoholism.

The purpose of this research study was to determine the overall effectiveness of computer-based laboratory compared with the traditional hands-on laboratory for improving students' science academic achievement and attitudes towards science subjects at the college and pre-college levels of education in the United States. Meta-analysis was used to synthesis the findings from 38 primary research studies conducted and/or reported in the United States between 1996 and 2006 that compared the effectiveness of computer-based laboratory with the traditional hands-on laboratory on measures related to science academic achievements and attitudes towards science subjects. The 38 primary research studies, with total subjects of 3,824 generated a total of 67 weighted individual effect sizes that were used in this meta-analysis. The study found that computer-based laboratory had small positive effect sizes over the traditional hands-on laboratory (ES = +0.26) on measures related to students' science academic achievements and attitudes towards science subjects (ES = +0.22). It was also found that computer-based laboratory produced more significant effects on physical science subjects compared to biological sciences (ES = +0.34, +0.17).

Different Types of Sounds and Their Relationship With the Electrocardiographic Signals and the Cardiovascular System – Review

PubMed Central

Idrobo-Ávila, Ennio H.; Loaiza-Correa, Humberto; van Noorden, Leon; Muñoz-Bolaños, Flavio G.; Vargas-Cañas, Rubiel

2018-01-01

Background: For some time now, the effects of sound, noise, and music on the human body have been studied. However, despite research done through time, it is still not completely clear what influence, interaction, and effects sounds have on human body. That is why it is necessary to conduct new research on this topic. Thus, in this paper, a systematic review is undertaken in order to integrate research related to several types of sound, both pleasant and unpleasant, specifically noise and music. In addition, it includes as much research as possible to give stakeholders a more general vision about relevant elements regarding methodologies, study subjects, stimulus, analysis, and experimental designs in general. This study has been conducted in order to make a genuine contribution to this area and to perhaps to raise the quality of future research about sound and its effects over ECG signals. Methods: This review was carried out by independent researchers, through three search equations, in four different databases, including: engineering, medicine, and psychology. Inclusion and exclusion criteria were applied and studies published between 1999 and 2017 were considered. The selected documents were read and analyzed independently by each group of researchers and subsequently conclusions were established between all of them. Results: Despite the differences between the outcomes of selected studies, some common factors were found among them. Thus, in noise studies where both BP and HR increased or tended to increase, it was noted that HRV (HF and LF/HF) changes with both sound and noise stimuli, whereas GSR changes with sound and musical stimuli. Furthermore, LF also showed changes with exposure to noise. Conclusion: In many cases, samples displayed a limitation in experimental design, and in diverse studies, there was a lack of a control group. There was a lot of variability in the presented stimuli providing a wide overview of the effects they could produce in humans. In the listening sessions, there were numerous examples of good practice in experimental design, such as the use of headphones and comfortable positions for study subjects, while the listening sessions lasted 20 min in most of the studies.

Thus, in this paper, a systematic review is undertaken in order to integrate research related to several types of sound, both pleasant and unpleasant, specifically noise and music. In addition, it includes as much research as possible to give stakeholders a more general vision about relevant elements regarding methodologies, study subjects, stimulus, analysis, and experimental designs in general. This study has been conducted in order to make a genuine contribution to this area and to perhaps to raise the quality of future research about sound and its effects over ECG signals. Methods: This review was carried out by independent researchers, through three search equations, in four different databases, including: engineering, medicine, and psychology. Inclusion and exclusion criteria were applied and studies published between 1999 and 2017 were considered. The selected documents were read and analyzed independently by each group of researchers and subsequently conclusions were established between all of them. Results: Despite the differences between the outcomes of selected studies, some common factors were found among them. Thus, in noise studies where both BP and HR increased or tended to increase, it was noted that HRV (HF and LF/HF) changes with both sound and noise stimuli, whereas GSR changes with sound and musical stimuli. Furthermore, LF also showed changes with exposure to noise. Conclusion: In many cases, samples displayed a limitation in experimental design, and in diverse studies, there was a lack of a control group. There was a lot of variability in the presented stimuli providing a wide overview of the effects they could produce in humans. In the listening sessions, there were numerous examples of good practice in experimental design, such as the use of headphones and comfortable positions for study subjects, while the listening sessions lasted 20 min in most of the studies.

The current study examines the trajectories of student perceived gains as a result of time spent in an undergraduate research experience (URE). Data for the study come from a survey administered at three points over a 1-yr period: before participation in the program, at the end of a Summer segment of research, and at the end of the year. Repeated-measures analysis of variance was used to examine the effect of time on perceived gains in student research skills, research confidence, and understanding of research processes. The results suggest that the students experienced different gains/benefits at developmentally different stages of their UREs. Participants reported gains in fewer areas at the end of the Summer segment compared with the end of the yearlong experience, thus supporting the notion that longer UREs offer students more benefit.

Male contraceptive development in the present scenario is most viable aspect of research due to uncontrolled population growth in the world. In this respect investigators are busy to find out a safe male contraceptive drug. Researchers have started their finding for a suitable drug from natural sources because these are safe and easily acceptable for common man, most of natural sources are plants and their products. In this review 137 plants and their effects on reproduction and reproductive physiology are summarized. Some of them have intense effect on male reproductive system and do not produce any side effects. Reproductive toxicological studies are also important aspects of these kinds of researches, so it is important that drugs are safe and widely acceptable. An ideal male contraceptive can influence semen, testes, hormone level, accessory reproductive organs and general physiology of animals and produced some alterations. Many plants in this review are showing antifertility as well as antispermatogenic effects, so these may be used for further study for contraceptives development but it is important to find out the mechanism of reaction and further laboratory and clinical research on some plants are needed for final male contraceptive drug development. In conclusion this review will help for finding suitable plant products for male contraceptive clinical and laboratory studies.

How lay people respond to messages about genetics, health, and race.

PubMed

Condit, C; Bates, B

2005-08-01

There is a growing movement in medical genetics to develop, implement, and promote a model of race-based medicine. Although race-based medicine may become a widely disseminated standard of care, messages that advocate race-based selection for diagnosing, screening and prescribing drugs may exacerbate health disparities. These messages are present in clinical genetic counseling sessions, mass media, and everyday talk. Messages promoting linkages among genes, race, and health and messages emphasizing genetic causation may promote both general racism and genetically based racism. This mini-review examines research in three areas: studies that address the effects of these messages about genetics on levels of genetic determinism and genetic discrimination; studies that address the effects of these messages on attitudes about race; and, studies of the impacts of race-specific genetic messages on recipients. Following an integration of this research, this mini-review suggests that the current literature appears fragmented because of methodological and measurement issues and offers strategies for future research. Finally, the authors offer a path model to help organize future research examining the effects of messages about genetics on socioculturally based racism, genetically based racism, and unaccounted for racism. Research in this area is needed to understand and mitigate the negative attitudinal effects of messages that link genes, race, and health and/or emphasize genetic causation.
