Enrolled nurses (ENs) across Australia precept nursing students in the clinical field. Yet learning about the preceptoring role is not widely available to ENs. Educational innovation: EN's in this study participated in a professional development project that utilised the material of an online learning resource, originally designed to inspire clinical registered nurses (RNs), and RN teachers, to develop teaching innovations in their role. The aim of this paper is to report the results of a pre-post-test questionnaire designed to evaluate the impact of the professional development intervention. The analysis showed high scoring means with many items in the questionnaire statistically significant (p < .05, CI 95%). Results indicated positive differences in a number of teaching capabilities between pre- and post-test scores. This suggests ENs appreciate education that extends beyond clinical skills and that professional development should include the nursing education role.

To present the results from the test site application of the documentation model KPO (quality assurance, problem solving and caring) designed to impact the quality of nursing information in electronic patient record (EPR). The KPO model was developed by means of consensus group and clinical testing. Four documentation arenas and eight content categories, nursing terminologies and a decision-support system were designed to impact the completeness, comprehensiveness and consistency of nursing information. The testing was performed in a pre-test/post-test time series design, three times at a one-year interval. Content analysis of nursing documentation was accomplished through the identification, interpretation and coding of information units. Data from the pre-test and post-test 2 were subjected to statistical analyses. To estimate the differences, paired t-tests were used. At post-test 2, the information is found to be more complete, comprehensive and consistent than at pre-test. The findings indicate that documentation arenas combining work flow and content categories deduced from theories on nursing practice can influence the quality of nursing information. The KPO model can be used as guide when shifting from paper-based to electronic-based nursing documentation with the aim of obtaining complete, comprehensive and consistent nursing information. © 2012 Blackwell Publishing Ltd.

Evaluating the efficacy of a chemistry video game

Shapiro, Marina

A quasi-experimental design pre-test/post-test intervention study utilizing a within group analysis was conducted with 45 undergraduate college chemistry students that investigated the effect of implementing a game-based learning environment into an undergraduate college chemistry course in order to learn if serious educational games (SEGs) can be used to achieve knowledge gains of complex chemistry concepts and to achieve increase in students' positive attitude toward chemistry. To evaluate if students learn chemistry concepts by participating in a chemistry game-based learning environment, a one-way repeated measures analysis of variance (ANOVA) was conducted across three time points (pre-test, post-test, delayed post-test which were chemistry content exams). Results showed that there was an increase in exam scores over time. The results of the ANOVA indicated a statistically significant time effect. To evaluate if students' attitude towards chemistry increased as a result of participating in a chemistry game-based learning environment a paired samples t-test was conducted using a chemistry attitudinal survey by Mahdi (2014) as the pre- and post-test. Results of the paired-samples t-test indicated that there was no significant difference in pre-attitudinal scores and post-attitudinal scores.

A study to compare traditional and constructivism-based instruction of a high school biology unit on biosystematics

NASA Astrophysics Data System (ADS)

Saigo, Barbara Woodworth

The researcher collaborated with four high school biology teachers who had been involved for 2-1/2 years in a constructivism-based professional development experience that emphasized teaching for conceptual change and using classroom-based inquiry as a basis for making instructional decisions. The researcher and teachers designed a five-day instructional unit on biosystematics using two contrasting approaches, comprising the treatment variable. The "traditional" unit emphasized lecture, written materials, and some laboratory activities. The "constructivist" unit emphasized a specific, inquiry-based, conceptual change strategy and collaborative learning. The study used a quasi-experimental, factorial design to explore impact of instructional approach (the treatment variable) on student performance (the dependent variable) on repeated measures (three) of a biology concept test. Additional independent variables considered were gender, cumulative GPA, and the section in which students were enrolled. Scores on the biology concept test were compiled for the 3 constructivist sections (N = 44) and the 3 traditional sections (N = 42). Analysis of Covariance (ANCOVA) was applied. The main findings in regard to the primary research question were that instructional approach did not have a significant relationship to immediate post test scores or gain, but that one month after instruction students in the constructivist group demonstrated less loss of gain than those in the traditional group; i.e., their longer-term retention was greater. Also, GPA*instructional approach effects were detected for post-post-test gain. GPA and gender were significantly associated with pre-test, post-test, and post-post scores; however, in terms of change (gain) from pre-test to post-test and pre-test to post-post-test, GPA and gender were not significant effects. Section was a significant effect for all three tests, in terms of both score and gain. Gender*section effects were detected for post-test gain and post-post-test scores.

2017-09-01

Research about the implementation of the Peer Assisted Learning (PAL) strategy in Plant Physiology lecture has carried out, in which it aims to improve students’ physiologic literacy. The PAL strategy began with a briefing by the lecturers to the students tutor about pretest questions, followed by the interaction between student tutors with their peers to discuss response problems, terminated by answering responsiveness questions individually. This study used a quasi-experimental method, one - group pre-test post-test design. This design includes a group of students observed in the pre-test phase (tests carried out before PAL treatment) which is then followed by treatment with PAL and ends with post-test. The other students group (control) was given the pre-test and post-test only. The results showed that the PAL strategy can increase student’s physiologic literacy significantly. One of the weaknesses of students’ physiologic literacy is that they have not been able to read the graph. The faculties are encouraged to begin introducing and teaching material using a variety of strategies with scientific literacy aspects, for example teaching research-based material. All students respond positively to the PAL strategy.

Background and purpose: The aim of this study was to explore the effect of investigative activities with manipulations in a virtual laboratory on students' ability to design experiments. Sample Fourteen students in a lower secondary school in Greece attended a teaching sequence on thermal phenomena based on the use of information and communication technology, and specifically of the simulated virtual laboratory 'ThermoLab'. Design and methods A pre-post comparison was applied. Students' design of experiments was rated in eight dimensions; namely, hypothesis forming and verification, selection of variables, initial conditions, device settings, materials and devices used, process and phenomena description. A three-level ranking scheme was employed for the evaluation of students' answers in each dimension. Results A Wilcoxon signed-rank test revealed a statistically significant difference between the students' pre- and post-test scores. Additional analysis by comparing the pre- and post-test scores using the Hake gain showed high gains in all but one dimension, which suggests that this improvement was almost inclusive. Conclusions We consider that our findings support the statement that there was an improvement in students' ability to design experiments.

Objective: To evaluate the effect of information provided before surgery on the self-esteem and body image of women undergoing hysterectomy. Materials and Methods: The study had a semi-experimental design with pre-post tests. A total of 60 women were included in the study and divided into two groups, the intervention group (n=30) and control group (n=30). A questionnaire, the Rosenberg self-esteem scale, and the body image scale were used to collect data. Results: The pre- and post-test body image scores were similar in the intervention group patients, but the post-test scores were significantly higher in the control group (p<0.05). The pre- and post-test self-esteem scores were again similar in the intervention group, but the post-test scores were significantly lower in the control group (p<0.05). Conclusion: This study revealed that health education given to patients prior to hysterectomy protects body image and consequently self-esteem. PMID:28913071

Padmavathi, P

2014-01-01

Premenstrual syndrome is the most common of gynaecologic complaints. It affects half of all female adolescents today and represents the leading cause of college/school absenteeism among that population. It was sought to assess the effectiveness of acupressure Vs reflexology on premenstrual syndrome among adolescents. Two-group pre-test and post-test true experimental design was adopted for the study. Forty adolescent girls from Government Girls Secondary School, Erode with pre- menstrual syndrome fulfilling the inclusion criteria were selected by simple random sampling. A pre-test was conducted by using premenstrual symptoms assessment scale. Immediately after pre-test acupressure Vs reflexology was given once a week for 6 weeks and again post-test was conducted to assess the effectiveness of treatment. Collected data was analysed by using descriptive and inferential statistics. In post-test, the mean score of the experimental group I sample was 97.3 (SD = 2.5) and the group II mean score was 70:8 (SD = 10.71) with paired 't' value of 19.2 and 31.9. This showed that the reflexology was more effective than acupressure in enhancing the practice of the sample regarding pre-menstrual syndrome. Statistically no significant association was found between the post-test scores of the sample with their demographic variables. The findings imply the need for educating adolescent girls on effective management of pre-menstrual syndrome.

Sub-Saharan Africa is among the countries where 10% of girls become mothers by the age of 16 years old. The United Republic of Tanzania located in Sub-Saharan Africa is one country where teenage pregnancy is a problem facing adolescent girls. Adolescent pregnancy has been identified as one of the reasons for girls dropping out from school. This study's purpose was to evaluate a reproductive health awareness program for the improvement of reproductive health for adolescents in urban Tanzania. A quasi-experimental pre-test and post-test research design was conducted to evaluate adolescents' knowledge, attitude, and behavior about reproductive health before and after the program. Data were collected from students aged 11 to 16, at Ilala Municipal, Dar es Salaam, Tanzania. An anonymous 23-item questionnaire provided the data. The program was conducted using a picture drama, reproductive health materials and group discussion. In total, 313 questionnaires were distributed and 305 (97.4%) were useable for the final analysis. The mean age for girls was 12.5 years and 13.2 years for boys. A large minority of both girls (26.8%) and boys (41.4%) had experienced sex and among the girls who had experienced sex, 51.2% reported that it was by force. The girls' mean score in the knowledge pre-test was 5.9, and 6.8 in post-test, which increased significantly (t=7.9, p=0.000). The mean behavior pre-test score was 25.8 and post-test was 26.6, which showed a significant increase (t=3.0, p=0.003). The boys' mean score in the knowledge pre-test was 6.4 and 7.0 for the post-test, which increased significantly (t=4.5, p=0.000). The mean behavior pre-test score was 25.6 and 26.4 in post-test, which showed a significant increase (t=2.4, p=0.019). However, the pre-test and post-test attitude scores showed no statistically significant difference for either girls or boys. Teenagers have sexual experiences including sexual violence. Both of these phenomena are prevalent among school-going adolescents. The reproductive health program improved the students' knowledge and behavior about sexuality and decision-making after the program for both girls and boys. However, their attitudes about reproductive health were not likely to change based on the educational intervention as designed for this study.

Background Conclusions drawn from meta-analyses on the association between soy isoflavone intake and breast cancer risk for pre- and post-menopausal women are not fully consistent. These meta-analyses did not explore the influence of different study designs on the pooled results on the basis of distinguishing between pre- and post-menopausal women. Methodology and Principal Findings We performed a meta-analysis of 35 studies which reported results of association between soy isoflavone intake and breast cancer risk for pre- and/or post-menopausal women, calculated pooled odds ratios and their 95% confidence intervals of pre- and post-menopausal women respectively, and further explored soy isoflavone-breast cancer association on the basis of considering different study regions and designs. Summary results suggested that soy isoflavone intake has a protective effect against breast cancer for both pre- and post-menopausal women. However, they are influenced by study design and region. Pooled ORs of studies carried out in Asian countries suggested that soy isoflavone’s protective effect exist in both pre- and post-menopausal women (OR = 0.59, 95%CI: 0.48–0.69 for premenopausal women; OR = 0.59, 95%CI: 0.44–0.74 for postmenopausal women). However, there are some differences between the results pooled from different study designs for women in Asian countries (test for consistency, P = 0.04). Pooled OR of studies on postmenopausal women in Western countries suggested that soy isoflavone intake has a marginally significant protective effect (OR = 0.92; 95%CI: 0.83∼1.00), but further analyses stratifying by study design found no statistically significant association. Conclusions We meta-analyzed more and newer research results, and separated women according to menopausal status to explore soy isoflavone-breast cancer association. We founded that soy isoflavone intake could lower the risk of breast cancer for both pre- and post-menopausal women in Asian countries. However, for women in Western countries, pre- or post-menopausal, there is no evidence to suggest an association between intake of soy isoflavone and breast cancer. PMID:24586662

To develop, implement, and evaluate the effects of a school-based asthma educational program on Saudi primary school teachers' asthma awareness and competence in delivering asthma-related first aid interventions. An asthma educational intervention program entitled "School Asthma Action Program" (SAAP) was designed based on pedagogical principles and implemented among teachers randomly selected from girls' primary schools in Riyadh, Saudi Arabia. This pilot study employed a pre-test/post-test experimental design. A previously tested asthma awareness questionnaire and a custom-designed asthma competence score sheet were used to evaluate the effects of the educational intervention program on teacher's asthma awareness and competence in providing asthma-related first aid interventions at schools. Forty-seven teachers from five different primary schools participated in the program. Of the 47 teachers, 39 completed both the pre- and post-program questionnaires. The SAAP improved teachers' awareness of asthma (teachers' median pre-program score was 11 (range 5-18) and their post-program score was 15 (range 7-18), p < 0.001) and their attitudes toward asthma management at schools (teachers' median pre-program score was 74 (range 15-75) and their post-program score was 75 (range 15-75), p = 0.043). Further, it improved teachers' competence in providing asthma-related first aid interventions (teachers' mean pre-program score was 1.4 ± 2.3 and their mean post-program score was 9.8 ± 0.5, p < 0.001). After completing the SAAP, a high proportion of teachers reported increased confidence in providing care to children with asthma at school. School-based asthma educational programs can significantly improve teachers' knowledge of asthma and their competence in providing asthma-related first aid interventions during emergencies.

Evaluating psycho-educational interventions for informal carers of patients receiving cancer care or palliative care: strengths and limitations of different study designs.

PubMed

Schildmann, Eva K; Higginson, Irene J

2011-06-01

Despite evidence of negative psychological sequelae and unmet needs, there are few evaluated interventions for informal caregivers in cancer and palliative care. The aim of this article is to debate the strengths and limitations of randomized controlled trials (RCTs) and other designs that can be used to evaluate the effectiveness of these interventions. Psycho-educational interventions are used as example for this debate article, as a number of studies of various designs evaluating this type of intervention have been published. Systematic searching in Medline and the bibliography of a relevant systematic review identified five RCTs, one pre-test/post-test study with a control group and six one-group pre-test/post-test studies of psycho-educational interventions for caregivers. The methodological strengths and weaknesses were assessed. RCTs are seen as the gold standard, but can have important limitations in the context of carer intervention research, including biased recruitment and low generalizability, problems with blinding and attrition. Pre-test/post-test studies with a control group may be more feasible and more generalizable. Their crucial limitation is selection bias. Before-after studies are compromised by additional specific biases and therefore are the weakest of all discussed designs. After analysing the strengths and weaknesses of the mentioned study designs, this paper presents strategies to address the limitations of RCTs evaluating psycho-educational interventions for carers in cancer or palliative care. © The Author(s) 2011

Comparison of data analysis strategies for intent-to-treat analysis in pre-test-post-test designs with substantial dropout rates.

PubMed

Salim, Agus; Mackinnon, Andrew; Christensen, Helen; Griffiths, Kathleen

2008-09-30

The pre-test-post-test design (PPD) is predominant in trials of psychotherapeutic treatments. Missing data due to withdrawals present an even bigger challenge in assessing treatment effectiveness under the PPD than under designs with more observations since dropout implies an absence of information about response to treatment. When confronted with missing data, often it is reasonable to assume that the mechanism underlying missingness is related to observed but not to unobserved outcomes (missing at random, MAR). Previous simulation and theoretical studies have shown that, under MAR, modern techniques such as maximum-likelihood (ML) based methods and multiple imputation (MI) can be used to produce unbiased estimates of treatment effects. In practice, however, ad hoc methods such as last observation carried forward (LOCF) imputation and complete-case (CC) analysis continue to be used. In order to better understand the behaviour of these methods in the PPD, we compare the performance of traditional approaches (LOCF, CC) and theoretically sound techniques (MI, ML), under various MAR mechanisms. We show that the LOCF method is seriously biased and conclude that its use should be abandoned. Complete-case analysis produces unbiased estimates only when the dropout mechanism does not depend on pre-test values even when dropout is related to fixed covariates including treatment group (covariate-dependent: CD). However, CC analysis is generally biased under MAR. The magnitude of the bias is largest when the correlation of post- and pre-test is relatively low.

2010-01-01

The aim of this study was to evaluate an infant oral health education programme, using a pre-post test design, for parents attending a paediatric clinic. The subjects were parents attending the well baby appointments at 3, 6, and 9 months of age. The study participants were men and women, all with an infant between 3 and 12 months of age. A 16 question assessment in the form of a questionnaire was completed immediately before and after the introduction of a 30 min educational intervention in the form of a PowerPoint presentation and a video of infant oral hygiene for parents. The parents completed the questionnaire twice (pre-post test design) in the same visit. Recruited parents attended only one presentation. The presentation educated parents about infant oral health and provided anticipatory guidance. Forty-seven parents or caretakers participated in the study. On the pre-test 28% had a score of 70% or less, and on the post-test 87% got a score of 88% or better. On the pre-test, 72% had a score of 70% or higher, and on the post-test 87% got a score of 88% or higher. Most parents (80%) reported that the presentation was helpful and indicated that the information would change the way they care for their baby's teeth at home. This study demonstrated the effectiveness of a 30 min PowerPoint and Video presentation in improving the oral health knowledge of parents caring for an infant.

This mixed method study used a pre-test/post-test design to evaluate the efficacy of a teaching strategy in improving beginning nursing student learning outcomes. During a 4-week student teaching period, a convenience sample of 54 sophomore level nursing students were required to complete calculation assignments, taught one calculation method, and mandated to attend medication calculation classes. These students completed pre- and post-math tests and a major medication mathematic exam. Scores from the intervention student group were compared to those achieved by the previous sophomore class. Results demonstrated a statistically significant improvement from pre- to post-test and the students who received the intervention had statistically significantly higher scores on the major medication calculation exam than did the students in the control group. The evaluation completed by the intervention group showed that the students were satisfied with the method and outcome.

Infectious disease is a major public health issue for both developed and developing countries. Among infectious diseases, tuberculosis (TB) is most prevalent in the develop- ing countries. India is the highest TB burden country in the world and accounts for nearly one fifth (20%) of global burden of tuberculosis. A pre-experimental design where pre- and post-test without control group with experimental approach was undertaken in Kuchinda block of Sambalpur district (Odisha) with the objectives to assess effectiveness of Video-assisted Teaching Module (VATM) on knowledge of Accredited Social Health Activists (ASHAs) regarding Revised National Tuberculosis Control Programme (RNTCP) Data were collected from 52 ASHAs, selected by systematic random sampling technique through structured questionnaire. The overall mean score in pre-test was 23.31±3.07 which is 58.27 percent of maximum score and good knowledge whereas it was 34.35±3.56 while post-test it was 85.87 percent of maximum score during post-test showing a difference of 27.6 percent effectiveness. Highly significant (p<0.01) differ- ence was found between pre- and post-test knowledge score and no significant (>0.05) association was found between post-test knowledge score when compared to all the demographic variables of ASHAs.

The purpose of the present study was to determine the efficacy of using music as a remedial strategy to enhance the reading skills of second-grade students and students who have been identified as having a specific learning disability (SLD) in reading. First, an intensive short-term music curriculum was designed to target reading comprehension and vocabulary skills at the second grade level. The curriculum was then implemented in classrooms at two public schools in the Southeast. Reading skills were evaluated pre and post curriculum intervention via the vocabulary and reading comprehension subtests of the Gates-MacGinitie Reading Test for second grade. Analysis of pre/posttest data revealed that students with a specific disability in reading improved significantly from pre to post on all three subtests: word decoding (p = .04), word knowledge (p = .01), reading comprehension (p = .01), and test total (p = .01). Paired t-tests revealed that for 2nd grade students, both treatment and control classes improved significantly from pre to post on the subtests word decoding, word knowledge, and test total. While both classes made gains from pre to post on the subtest, reading comprehension, neither improved significantly. Analysis of Covariance revealed that the treatment class made greater gains pre to post than the control class on all 3 subtests (Including reading comprehension), and significantly greater gains on the subtest, word knowledge (p = .01).

Avşar, Fatma; Ayaz Alkaya, Sultan

The aim of this study was to determine the effectiveness of an assertive training for school-aged children on peer bullying and assertiveness. A quasi-experimental design using pre- and post-testing was conducted. Data were collected using a demographic questionnaire, an assertiveness scale, and the peer victimization scale. The training program was comprised of eight sessions which were implemented to intervention group. Descriptive characteristics were not statistically different between the groups (p>0.05). The peer victimization victim dimension results show that post-test mean scores of the students in the intervention group were lower than the pre-test mean scores (p<0.05). For the control group, no significant change was found in the pre-test and post-test mean scores (p>0.05). A comparison of the mean pre-test/post-test scores of peer-victimization bully dimension of the students' intervention and control groups revealed that the mean post-test scores of the students in the each group decreased (p>0.05). An assertiveness training program increased the assertiveness level and reduced the state of being victims, but did not affect the state of being bullies. The results of this study can help children acquire assertive behaviors instead of negative behaviors such as aggression and shyness, and help them to build effective social communication.

This paper describes a project designed to facilitate the use of research in nursing practice in one acute hospital. A university team worked in collaboration with staff from the hospital to develop and evaluate the impact of development work designed to enhance knowledge and use of research in practice. A research utilization questionnaire was administered as a pre-test (stage 1); a development phase was implemented (stage 2) and a post-test survey (stage 3) was administered to evaluate the impact of the development work. In stage 1, the total population of nursing and midwifery staff in the hospital (n=473) were targeted and 235 returned the questionnaire, giving a response rate of 50%. Data from the pre-test and focus group discussions with staff were used to plan stage 2 of the project. The development stage involved an educational strand in which open learning research materials were made available to staff, who were also offered tutorial support in their learning. A second strand supported the development of clinical research projects and funds were identified for clinical staff to apply for project development awards to enable them to develop skills in research and development activity under the supervision of a research fellow. Stage 3 involved a post-test survey of staff who had completed the questionnaire in stage 1 (n=81). There were no significant differences in findings between the pre-test and post-test. Qualitative data from those involved in the clinical projects in stage 2 indicated factors impacting on the feasibility of undertaking research in practice.

Post partum psychiatric illnesses are quiet common nowadays, which can interfere with postnatal care of both mother and infant. The present study was a one group pre-test - post-test design, adopted with an aim to enhance the knowledge on mother infant health among primary caregivers of mothers with postpartum psychiatric illnesses conducted in the mother-baby unit, NIMHANS, Bengaluru. Twenty five subjects who met the inclusion criteria were recruited through convenience sampling. After the pilot study, data was collected with a researcher developed tool. The Video Assisted Psycho-Education [VAPE] consisted of three sessions lasting for thirty minutes, taken over three consecutive days following the pre-test. Post-test was done immediately after the last session. Effectiveness of the intervention was established by McNemar test, Paired t-test and Wilcoxon Sign Ranks test. Analysis revealed statistically significant (p<0.001) increase in the post-test mean knowledge scores following the VAPE sessions. There was no statistically significant association between the pre-intervention knowledge score and the socio-demographic variables of the study subjects. The study findings revealed that the VAPE programme was effective in increasing the knowledge of the primary caregivers on mother infant health. Copyright © 2017 Elsevier B.V. All rights reserved.

In Germany, studies in rehabilitation research--in particular evaluation studies and examinations of quality of outcome--have so far mostly been executed according to the uncontrolled one-group pre-post design. Assessment of outcome is usually made by comparing the pre- and post-treatment means of the outcome variables. The pre-post differences are checked, and in case of significance, the results are increasingly presented in form of effect sizes. For this reason, this contribution presents different effect size indices used for the one-group pre-post design--in spite of fundamental doubts which exist in relation to that design due to its limited internal validity. The numerator concerning all effect size indices of the one-group pre-post design is defined as difference between the pre- and post-treatment means, whereas there are different possibilities and recommendations with regard to the denominator and hence the standard deviation that serves as the basis for standardizing the difference of the means. Used above all are standardization oriented towards the standard deviation of the pre-treatment scores, standardization oriented towards the pooled standard deviation of the pre- and post-treatment scores, and standardization oriented towards the standard deviation of the pre-post differences. Two examples are given to demonstrate that the different modes of calculating effect size indices in the one-group pre-post design may lead to very different outcome patterns. Additionally, it is pointed out that effect sizes from the uncontrolled one-group pre-post design generally tend to be higher than effect sizes from studies conducted with control groups. Finally, the pros and cons of the different effect size indices are discussed and recommendations are given.

Myocardial perfusion scintigraphy (MPS) is a diagnostic test which is frequently used in the diagnosis of coronary heart disease (CHD). MPS is generally interpreted as ischemia present or absent; however, it has a power in predicting the disease, similar to other diagnostic tests. In this study, we aimed to assist in directing the high-risk patients to undergo coronary angiography (CA) primarily by evaluating patients without prior CHD history with pre-test and post-test probabilities. The study was designed as a retrospective study. Between January 2008 and July 2011, 139 patients with positive MPS results and followed by CA recently (<6 months) were evaluated from patient files. Patients' pre-test probabilities based on the Diamond and Forrester method and the likelihood ratios that were obtained from the literature were used to calculate the patients' post exercise and post-MPS probabilities. Patients were evaluated in risk groups as low, intermediate, and high, and an ROC curve analysis was performed for the post-MPS probabilities. Coronary artery stenosis (CAS) was determined in 59 patients (42.4%). A significant difference was determined between the risk groups according to CAS, both for the pre-test and post-test probabilities (p<0.001, p=0.024). The ROC analysis provided a cut-off value of 80.4% for post- MPS probability in predicting CAS with 67.9% sensitivity and 77.8% specificity. When the post-MPS probability is ≥80% in patients who have reversible perfusion defects on MPS, we suggest interpreting the MPS as "high probability positive" to improve the selection of true-positive patients to undergo CA, and these patients should be primarily recommended CA.

Background According to new Norwegian laws, mental healthcare for adults are obligated to assess all patients who are parents and to act on their children's needs. This article describes the study protocol of implementing the interventions Family Assessment and Child Talks for children of patients in the adult psychiatry of the University Hospital of Northern Norway. The project is designed to evaluate the process of changes in clinical practice due to the implementation of two interventions. The interventions to be implemented are a standardised Family Assessment Form and the intervention called Child Talks. The family assessment form is an intervention to identify children of mentally ill parents and their needs. The intervention Child Talks is a health-promoting and preventive intervention where the mental health workers talk with the family about the situation of the children and their needs. Methods/design There are two groups of participants in this study: (1) mental health workers in the clinic (N=220) and (2) patients who are parents (N=200) receiving treatment in the clinic. (1) In the evaluation of clinical practice, the authors use a pre-test, post-test and 1-year follow-up design. At pre-test, the authors evaluate status quo among mental health workers in the clinic regarding knowledge, attitudes, collaborative routines and clinical practice related to families with parental mental illness. After the pre-test is finished, the project move on to implement the interventions Family Assessment Form and Child Talks in the clinic. At post-test and 1-year follow-up, the authors evaluate the impact of implementing the Family Assessment Form in terms of how many children were identified and offered Child Talks in the clinic or referred to other services for additional support. (2) In the evaluation of parents/patients experience with the interventions, the authors use a pre-test post-test design. To identify children of mentally ill patients, the authors collect data on demographical variables for the patient and the child at pre-measures, as well as data on parental competence (PSOC) and parental concerns (PEDS) about their children. At post-measures, the authors evaluate the impact of the intervention in terms of user satisfaction, as well as changes between pre- and post-measures on parental competence (PSOC) and parental concerns (PEDS) about their children. Discussion The implication of implementing new interventions to safeguard children of mentally ill patients and the limitation of not measuring child development directly are discussed.

Although statistical knowledge and skills are necessary for promoting evidence-based practice, health sciences students have expressed anxiety about statistics courses, which may hinder their learning of statistical concepts. To evaluate the effects of a biostatistics course on nursing students' attitudes toward statistics and to explore the association between these attitudes and their performance in the course examination. One-group quasi-experimental pre-test/post-test design. Undergraduate nursing students of the fifth or higher semester of studies, who attended a biostatistics course. Participants were asked to complete the pre-test and post-test forms of The Survey of Attitudes Toward Statistics (SATS)-36 scale at the beginning and end of the course respectively. Pre-test and post-test scale scores were compared, while correlations between post-test scores and participants' examination performance were estimated. Among 156 participants, post-test scores of the overall SATS-36 scale and of the Affect, Cognitive Competence, Interest and Effort components were significantly higher than pre-test ones, indicating that the course was followed by more positive attitudes toward statistics. Among 104 students who participated in the examination, higher post-test scores of the overall SATS-36 scale and of the Affect, Difficulty, Interest and Effort components were significantly but weakly correlated with higher examination performance. Students' attitudes toward statistics can be improved through appropriate biostatistics courses, while positive attitudes contribute to higher course achievements and possibly to improved statistical skills in later professional life.

Program evaluations are frequently based on 'then-test' data, i.e., pre-test collected in retrospect. While the application of the then-test has practical advantages, little is known about the validity of then-test data. Because of the collection of then-test in close proximity to post-test questions, this study was aimed at exploring whether the presence of then-test questions in post-test questionnaires influenced subjects' responses to post-test. To test the influence of then-test questions, we designed a randomized three-group study in the context of chronic disease self-management programs. Interventions had comparable goals and philosophies, and all 949 study participants filled out identical Health Education Impact Questionnaires (heiQ) at pre-test. At post-test, participants were then randomized to one of the following three groups: Group A responded to post-test questions only (n = 331); Group B filled out transition questions in addition to post-test (n = 304); and Group C filled out then-test questions in addition to post-test (n = 314). Significant post-test differences were found in six of eight heiQ scales, with respondents who filled out then-test questions reporting significantly higher post-test scores than respondents of the other groups. This study provides evidence that the inclusion of then-test questions alters post-test responses, suggesting that change scores based on then-test data be interpreted with care.

To increase adherence with intensive care unit mobility by developing and implementing a mobility training program that addresses nursing barriers to early mobilisation. An intensive care unit mobility training program was developed, implemented and evaluated with a pre-test, immediate post-test and eight-week post-test. Patient mobility was tracked before and after training. A ten bed cardiac intensive care unit. The training program's efficacy was measured by comparing pre-test, immediate post-test and 8-week post-test scores. Patient mobilisation rates before and after training were compared. Protocol compliance was measured in the post training group. Nursing knowledge increased from pre-test to immediate post-test (p<0.0001) and pre-test to 8-week post-test (p<0.0001). Mean test scores decreased by seven points from immediate post-test (80±12) to 8-week post-test (73±14). Fear significantly decreased from pre-test to immediate post-test (p=0.03), but not from pre-test to 8-week post-test (p=0.06) or immediate post-test to 8-week post-test (p=0.46). Post training patient mobility rates increased although not significantly (p=0.07). Post training protocol compliance was 78%. The project successfully increased adherence with intensive care unit mobility and indicates that a training program could improve adoption of early mobility. Copyright © 2016 Elsevier Ltd.

beta-Alanine (betaA) has been shown to improve performance during cycling. This study was the first to examine the effects of betaA supplementation on the onset of blood lactate accumulation (OBLA) during incremental treadmill running. Seventeen recreationally-active men (mean +/- SE 24.9 +/- 4.7 yrs, 180.6 +/- 8.9 cm, 79.25 +/- 9.0 kg) participated in this randomized, double-blind, placebo-controlled pre/post test 2-treatment experimental design. Subjects participated in two incremental treadmill tests before and after 28 days of supplementation with either betaA (6.0 g.d-1)(betaA, n = 8) or an equivalent dose of Maltodextrin as the Placebo (PL, n = 9). Heart rate, percent heart rate maximum (%HRmax), %VO2max@OBLA (4.0 mmol.L-1 blood lactate concentration) and VO2max (L.min-1) were determined for each treadmill test. Friedman test was used to determine within group differences; and Mann-Whitney was used to determine between group differences for pre and post values (p < 0.05). The betaA group experienced a significant rightward shift in HR@OBLA beats.min-1 (p < 0.01) pre/post (161.6 +/- 19.2 to 173.6 +/- 9.9) but remained unchanged in the PL group (166.8 +/- 15.8 to 169.6 +/- 16.1). The %HRmax@OBLA increased (p < 0.05) pre/post in the betaA group (83.0% +/- 9.7 to 88.6% +/- 3.7) versus no change in the PL group (86.3 +/- % 4.8 to 87.9% +/- 7.2). The %VO2max@OBLA increased (p < 0.05) in the betaA group pre/post (69.1 +/- 11.0 to 75.6 +/- 10.7) but remained unchanged in the PL group (73.3 +/- 7.3 to 74.3 +/- 7.3). VO2max (L.min-1) decreased (p < 0.01) in the betaA group pre/post (4.57 +/- 0.8 to 4.31 +/- 0.8) versus no change in the PL group (4.04 +/- 0.7 to 4.18 +/- 0.8). Body mass kg increased (p < 0.05) in the betaA group pre/post (77.9 +/- 9.0 to 78.3 +/- 9.3) while the PL group was unchanged (80.6 +/- 9.1 to 80.4 +/- 9.0). betaA supplementation for 28 days enhanced sub-maximal endurance performance by delaying OBLA. However, betaA supplemented individuals had a reduced aerobic capacity as evidenced by the decrease in VO2max values post supplementation.

This study was designed to examine the efficacy of video instruction relative to that of verbal and self-guided instruction. Before training, 30 golfers were assigned at random to one of three groups: video, verbal or self-guided instruction. Video instruction was defined as a practice session in which the teacher was aided by the use of video. Verbal instruction was defined as practising with the teacher providing verbal feedback. Self-guided practice was defined as practising without the aid of a teacher. The participants had a pre-test, four 90 min practice sessions, an immediate post-test and a 2 week delayed post-test. During the pre-test and post-tests, all participants were required to strike 15 golf balls, with a 7-iron, from an artificial turf mat for distance and accuracy. The results showed that all groups were equal on the pre-test. On the first post-test, the two instruction groups performed worse than the self-guided group. However, on the second post-test, the two instruction groups performed better than the self-guided group, with the video group performing best. We interpret these results to mean that video analysis is an effective means of practice, but that the positive effects may take some time to develop.

Cervical cancer is one of the leading causes of cancer in women worldwide. One way by which the incidence of this malignant disease can be minimized is by imparting knowledge through health education. This study aimed at developing an educational package on cervical cancer (EPCC) and determining its effectiveness in terms of significant increase in knowledge of rural women regarding cervical cancer. A one group pre-test, post-test design was adopted. Thirty rural women were selected using a convenient sampling method. Data were collected using a demographic questionnaire and a structured knowledge questionnaire developed by the researchers. The EPCC was designed for a duration of one hour and 10 minutes. The structured knowledge questionnaire was first administered as the pre-test, following which knowledge on cervical cancer was imparted using the EPCC. On the 8th day, the post-test was administered. Data were analyzed using descriptive and inferential statistics. The mean post-test knowledge score of the women regarding cervical cancer was significantly higher than that of their mean pre-test score, indicating that the EPCC was effective in improving the knowledge of rural women on cervical cancer. The association between pre-test knowledge scores and selected demo-graphic variables were computed using chi-square test showed that pre-test knowledge score of the women regarding cervical cancer was independent of all the socio-demographic variables. It was concluded that the EPCC is effective in improving the knowledge of women, regarding cervical cancer. Since the prevalence of cervical cancer is high, there is an immediate need to educate women on prevention of cervical cancer.

Detecting Intervention Effects in a Cluster-Randomized Design Using Multilevel Structural Equation Modeling for Binary Responses.

PubMed

Cho, Sun-Joo; Preacher, Kristopher J; Bottge, Brian A

2015-11-01

Multilevel modeling (MLM) is frequently used to detect group differences, such as an intervention effect in a pre-test-post-test cluster-randomized design. Group differences on the post-test scores are detected by controlling for pre-test scores as a proxy variable for unobserved factors that predict future attributes. The pre-test and post-test scores that are most often used in MLM are summed item responses (or total scores). In prior research, there have been concerns regarding measurement error in the use of total scores in using MLM. To correct for measurement error in the covariate and outcome, a theoretical justification for the use of multilevel structural equation modeling (MSEM) has been established. However, MSEM for binary responses has not been widely applied to detect intervention effects (group differences) in intervention studies. In this article, the use of MSEM for intervention studies is demonstrated and the performance of MSEM is evaluated via a simulation study. Furthermore, the consequences of using MLM instead of MSEM are shown in detecting group differences. Results of the simulation study showed that MSEM performed adequately as the number of clusters, cluster size, and intraclass correlation increased and outperformed MLM for the detection of group differences.

Quasi experimental designs in pharmacist intervention research.

PubMed

Krass, Ines

2016-06-01

Background In the field of pharmacist intervention research it is often difficult to conform to the rigorous requirements of the "true experimental" models, especially the requirement of randomization. When randomization is not feasible, a practice based researcher can choose from a range of "quasi-experimental designs" i.e., non-randomised and at time non controlled. Objective The aim of this article was to provide an overview of quasi-experimental designs, discuss their strengths and weaknesses and to investigate their application in pharmacist intervention research over the previous decade. Results In the literature quasi experimental studies may be classified into five broad categories: quasi-experimental design without control groups; quasi-experimental design that use control groups with no pre-test; quasi-experimental design that use control groups and pre-tests; interrupted time series and stepped wedge designs. Quasi-experimental study design has consistently featured in the evolution of pharmacist intervention research. The most commonly applied of all quasi experimental designs in the practice based research literature are the one group pre-post-test design and the non-equivalent control group design i.e., (untreated control group with dependent pre-tests and post-tests) and have been used to test the impact of pharmacist interventions in general medications management as well as in specific disease states. Conclusion Quasi experimental studies have a role to play as proof of concept, in the pilot phases of interventions when testing different intervention components, especially in complex interventions. They serve to develop an understanding of possible intervention effects: while in isolation they yield weak evidence of clinical efficacy, taken collectively, they help build a body of evidence in support of the value of pharmacist interventions across different practice settings and countries. However, when a traditional RCT is not feasible for logistical and/or ethical reasons researchers should endeavour to use the more robust of the quasi experimental designs.

Unnecessary pathology tests performed in intensive care units (ICU) might lead to increased costs of care and potential patient harm due to unnecessary phlebotomy. We hypothesised that a multimodal intervention program could result in a safe and effective reduction in the pathology tests ordered in our ICU. We conducted a single-centre pre- and post-study using multimodal interventions to address commonly ordered routine tests. The study was performed during the same six month period (August to February) over three years: 2012 to 2013 (pre-intervention), 2013 to 2014 (intervention) and 2014 to 2015 (post-intervention). Interventions consisted of staff education, designing new pathology forms, consultant-led pathology test ordering and intensive monitoring for a six-month period. The results of the study showed that there was a net savings of over A$213,000 in the intervention period and A$175,000 in the post-intervention period compared to the pre-intervention period. There was a 28% reduction in the tests performed in the intervention period (P <0.0001 compared to pre-intervention period) and 26% in the post-intervention period (P <0.0001 compared to pre-intervention period). There were no ICU or hospital mortality differences between the groups. There were no significant haemoglobin differences between the groups. A multimodal intervention safely reduced pathology test ordering in the ICU, resulting in substantial cost savings.

Aim To assess the utility of a multiple-encounter in-situ (MEIS) simulation as an orientation tool for multidisciplinary staff prior to opening a new paediatric emergency service. Methods A single-group pretest/post-test study was conducted. During the MEIS simulation, multidisciplinary staff with participant or observer roles managed eight children (mannequins) who attended triage with their parent/guardians (clinical facilitators) for a range of emergency presentations (structured scenarios designed to represent the expected range of presentations plus test various clinical pathways/systems). Participants were debriefed to explore clinical, systems and crisis-resource management issues. Participants also completed a pre-intervention and post-intervention questionnaire comprising statements about role confidence and orientation adequacy. Pre-test and post-test results were analysed using t-test and Wilcoxon signed rank test. Results Eighty-nine staff participated in the MEIS simulation, with the majority completing the pre-simulation and post-simulation questionnaire. There was a significant improvement in post-intervention versus pre-intervention Likert scores for role confidence and orientation adequacy (p=0.001 and <0.001, respectively); effect sizes suggested the greatest impact was on orientation adequacy. Nearly all scenarios resulted in significant increases in participants’ confidence levels. Conclusions The MEIS simulation was of utility in orientation of staff, at least with respect to self-reported role confidence and orientation adequacy. Its effectiveness in practice or compared with other orientation techniques was not assessed, but it did identify several flaws in planned systems allowing remediation prior to opening.

The four science crewmembers of Spacelab-1 were tested for postural control before and after a 10 day mission in weightlessness. Previous reports have shown changes in astronaut postural behavior following a return to earth's 1-g field. This study was designed to identify changes in EMG latency and amplitudes that might explain the instabilities observed post-flight. Erect posture was tested having the subject stand on a pneumatically driven posture platform which pitched rapidly and unexpectedly about the ankles causing dorsi- and plantarflexion. Electromyographic (EMG) activity from the tibialis anterior and the gastrocnemius-soleus muscles was measured during eyes open and eyes closed trials. The early (pre 500 ms) EMG response characteristics (latency, amplitude) in response to a disturbance in the posture of the subject were apparently unchanged by the 10 days of weightlessness. However, the late (post 500 ms) response showed higher amplitudes than was found pre-flight. General postural control was quantitatively measured pre- and post-flight by a 'sharpened Romberg Rails test'. This test showed decrements in standing stability with eyes closed for several days post-flight.

Detecting Intervention Effects in a Cluster-Randomized Design Using Multilevel Structural Equation Modeling for Binary Responses

Cho, Sun-Joo; Preacher, Kristopher J.; Bottge, Brian A.

2015-01-01

Multilevel modeling (MLM) is frequently used to detect group differences, such as an intervention effect in a pre-test–post-test cluster-randomized design. Group differences on the post-test scores are detected by controlling for pre-test scores as a proxy variable for unobserved factors that predict future attributes. The pre-test and post-test scores that are most often used in MLM are summed item responses (or total scores). In prior research, there have been concerns regarding measurement error in the use of total scores in using MLM. To correct for measurement error in the covariate and outcome, a theoretical justification for the use of multilevel structural equation modeling (MSEM) has been established. However, MSEM for binary responses has not been widely applied to detect intervention effects (group differences) in intervention studies. In this article, the use of MSEM for intervention studies is demonstrated and the performance of MSEM is evaluated via a simulation study. Furthermore, the consequences of using MLM instead of MSEM are shown in detecting group differences. Results of the simulation study showed that MSEM performed adequately as the number of clusters, cluster size, and intraclass correlation increased and outperformed MLM for the detection of group differences.

To embed an evidence-based intervention to manage FEver, hyperglycaemia (Sugar) and Swallowing (the FeSS protocols) in stroke, previously demonstrated in the Quality in Acute Stroke Care (QASC) trial to decrease 90-day death and dependency, into all stroke services in New South Wales (NSW), Australia's most populous state. Pre-test/post-test prospective study. 36 NSW stroke services. Our clinical translational initiative, the QASC Implementation Project (QASCIP), targeted stroke services to embed 3 nurse-led clinical protocols (the FeSS protocols) into routine practice. Clinical champions attended a 1-day multidisciplinary training workshop and received standardised educational resources and ongoing support. Using the National Stroke Foundation audit collection tool and processes, patient data from retrospective medical record self-reported audits for 40 consecutive patients with stroke per site pre-QASCIP (1 July 2012 to 31 December 2012) were compared with prospective self-reported data from 40 consecutive patients with stroke per site post-QASCIP (1 November 2013 to 28 February 2014). Inter-rater reliability was substantial for 10 of 12 variables. Proportion of patients receiving care according to the FeSS protocols pre-QASCIP to post-QASCIP. All 36 (100%) NSW stroke services participated, nominating 100 site champions who attended our educational workshops. The time from start of intervention to completion of post-QASCIP data collection was 8 months. All (n=36, 100%) sites provided medical record audit data for 2144 patients (n=1062 pre-QASCIP; n=1082 post-QASCIP). Pre-QASCIP to post-QASCIP, proportions of patients receiving the 3 targeted clinical behaviours increased significantly: management of fever (pre: 69%; post: 78%; p=0.003), hyperglycaemia (pre: 23%; post: 34%; p=0.0085) and swallowing (pre: 42%; post: 51%; p=0.033). We obtained unprecedented statewide scale-up and spread to all NSW stroke services of a nurse-led intervention previously proven to improve long-term patient outcomes. As clinical leaders search for strategies to improve quality of care, our initiative is replicable and feasible in other acute care settings. Published by the BMJ Publishing Group Limited.

Teaching habitat and animal classification to fourth graders using an engineering-design model

NASA Astrophysics Data System (ADS)

Marulcu, Ismail

2014-05-01

Background: The motivation for this work is built upon the premise that there is a need for research-based materials for design-based science instruction. In this paper, a small portion of our work investigating the impact of a LEGOTM engineering unit on fourth grade students' preconceptions and understanding of animals is presented. Purpose: The driving questions for our work are: (1) What is the impact of an engineering-design-based curricular module on students' understanding of habitat and animal classification? (2) What are students' misconceptions regarding animal classification and habitat? Sample: The study was conducted in an inner-city K-8 school in the northeastern region of the United States. There were two fourth grade classrooms in the school. The first classroom included seven girls and nine boys, whereas the other classroom included eight girls and eight boys. All fourth grade students participated in the study. Design and methods: In answering the research questions mixed-method approaches are used. Data collection methods included pre- and post-tests, pre- and post-interviews, student journals, and classroom observations. Identical pre- and post-tests were administered to measure students' understanding of animals. They included four multiple-choice and six open-ended questions. Identical pre- and post-interviews were administered to explore students' in-depth understanding of animals. Results: Our results show that students significantly increased their performance after instruction on both the multiple-choice questions (t = -3.586, p = .001) and the open-ended questions (t = -5.04, p = .000). They performed better on the post interviews as well. Also, it is found that design-based instruction helped students comprehend core concepts of a life science subject, animals. Conclusions: Based on these results, the main argument of the study is that engineering design is a useful framework for teaching not only physical science-related subjects, but also life science subjects in elementary science classrooms.

Evaluating workforce developments to support children of mentally ill parents: implementing new interventions in the adult mental healthcare in Northern Norway.

According to new Norwegian laws, mental healthcare for adults are obligated to assess all patients who are parents and to act on their children's needs. This article describes the study protocol of implementing the interventions Family Assessment and Child Talks for children of patients in the adult psychiatry of the University Hospital of Northern Norway. The project is designed to evaluate the process of changes in clinical practice due to the implementation of two interventions. The interventions to be implemented are a standardised Family Assessment Form and the intervention called Child Talks. The family assessment form is an intervention to identify children of mentally ill parents and their needs. The intervention Child Talks is a health-promoting and preventive intervention where the mental health workers talk with the family about the situation of the children and their needs. There are two groups of participants in this study: (1) mental health workers in the clinic (N=220) and (2) patients who are parents (N=200) receiving treatment in the clinic. (1) In the evaluation of clinical practice, the authors use a pre-test, post-test and 1-year follow-up design. At pre-test, the authors evaluate status quo among mental health workers in the clinic regarding knowledge, attitudes, collaborative routines and clinical practice related to families with parental mental illness. After the pre-test is finished, the project move on to implement the interventions Family Assessment Form and Child Talks in the clinic. At post-test and 1-year follow-up, the authors evaluate the impact of implementing the Family Assessment Form in terms of how many children were identified and offered Child Talks in the clinic or referred to other services for additional support. (2) In the evaluation of parents/patients experience with the interventions, the authors use a pre-test post-test design. To identify children of mentally ill patients, the authors collect data on demographical variables for the patient and the child at pre-measures, as well as data on parental competence (PSOC) and parental concerns (PEDS) about their children. At post-measures, the authors evaluate the impact of the intervention in terms of user satisfaction, as well as changes between pre- and post-measures on parental competence (PSOC) and parental concerns (PEDS) about their children. The implication of implementing new interventions to safeguard children of mentally ill patients and the limitation of not measuring child development directly are discussed.

To examine the potential effectiveness of a multimodal rehabilitation program including an acceptance-oriented cognitive-behavioral therapy for highly distressed patients with rheumatic diseases. An observational study employing a one-group pre-post test design (N=25). The primary outcome was psychological distress. Secondary outcomes were quality of life, illness acceptance, and coping flexibility. Group pre-to-post and pre-to-12 months follow-up treatment changes were evaluated by paired-samples t-tests and Cohen's effect sizes (d). Individual changes were evaluated by the reliable change index (RCI) and clinically significant change (CSC) parameters. Significant effects were found post-treatment and maintained at 12 months in psychological distress (d>0.80), illness acceptance (d=1.48) and the SF-36 subscales role physical, vitality, and mental health (d ≥ 0.65). No significant effects were found for coping flexibility and the SF-36 subscales physical functioning, bodily pain, social functioning, and role emotional. Both a reliable (RCI) and clinically significant (CSC) improvement was observed for almost half of the highly distressed patients. The patients enrolled in the multimodal rehabilitation program showed improved psychological health status from pre to post-treatment. A randomized clinical trial is needed to confirm or refute the added value of an acceptance-oriented cognitive-behavioral therapy for highly distressed patients in rehabilitation.

Teaching residents to lead end of life (EOL) and error disclosure (ED) conferences is important. We developed and tested an intervention using videotapes of EOL and error disclosure encounters from previous Objective Structured Clinical Exams. Residents (n = 72) from general and orthopedic surgery programs at 2 sites were enrolled. Using a prospective, pre-post, block group design with stratified randomization, we hypothesized the treatment group would outperform the control on EOL and ED cases. We also hypothesized that online course usage would correlate positively with post-test scores. All residents improved (pre-post). At the group level, treatment effects were insignificant, and post-test performance was unrelated to course usage. At the subgroup level for EOL, low performers assigned to treatment scored higher than controls at post-test; and within the treatment group, post graduate year 3 residents outperformed post graduate year ​1 residents. To be effective, online curricula illustrating communication behaviors need face-to-face interaction, individual role play with feedback and discussion. Copyright © 2016 Elsevier Inc.

The use of then-test (retrospective pre-test) scores has frequently been proposed as a solution to potential confounding of change scores because of response shift, as it is assumed that then-test and post-test responses are provided from the same perspective. However, this assumption has not been formally tested using robust quantitative methods. The aim of this study was to compare the psychometric performance of then-test/post-test with traditional pre-test/post-test data and assessing whether the resulting data structures support the application of the then-test for evaluations of chronic disease self-management interventions. Pre-test, post-test, and then-test data were collected from 314 participants of self-management courses using the Health Education Impact Questionnaire (heiQ). The derived change scores (pre-test/post-test; then-test/post-test) were examined for their psychometric performance using tests of measurement invariance. Few questionnaire items were noninvariant across pre-test/post-test, with four items identified and requiring removal to enable an unbiased comparison of factor means. In contrast, 12 items were identified and required removal in then-test/post-test data to avoid biased change score estimates. Traditional pre-test/post-test data appear to be robust with little indication of response shift. In contrast, the weaker psychometric performance of then-test/post-test data suggests psychometric flaws that may be the result of implicit theory of change, social desirability, and recall bias.

With the increasing adoption of peroral endoscopic myotomy (POEM) as a first-line therapy for achalasia as well as a growing list of other indications, it is apparent that there is a need for effective training methods for both endoscopists in training and those already in practice. We present a hands-on-focused with pre- and post-testing methodology to teach these skills. Six POEM courses were taught by 11 experienced POEM endoscopists at two independent simulation laboratories. The training curriculum included a pre-training test, lectures and discussion, mentored hands-on instruction using live porcine and ex-plant models, and a post-training test. The scoring sheet for the pre- and post-tests assessed the POEM performance with a Likert-like scale measuring equipment setup, mucosotomy creation, endoscope navigation, visualization, myotomy, and closure. Participants were stratified by their experience with upper-GI endoscopy (Novices <100 cases vs. Experts ≥100 cases), and their data were analyzed and compared. Sixty-five participants with varying degrees of experience in upper-GI endoscopy and laparoscopic achalasia cases completed the training curriculum. Participants improved knowledge scores from 69.7 ± 17.1 (pre-test) to 87.7 ± 10.8 (post-test) (p < 0.01). POEM performance increased from 15.1 ± 5.1 to 25.0 ± 5.5 (out of 30) (p < 0.01) with the greatest gains in mucosotomy [1.7-4.4 (out of 5), p < 0.01] and equipment (3.4-4.7, p < 0.01). Novices had significantly lower pre-test scores compared with Experts in upper-GI endoscopy (overall pre-score: 11.9 ± 5.6 vs. 16.3 ± 4.6, p < 0.01). Both groups improved significantly after the course, and there were no differences in post-test scores (overall post-score: 23.9 ± 6.6 vs. 25.4 ± 5.1, p = 0.34) between Novices and Experts. A multimodal curriculum with procedural practice was an effective curricular design for teaching POEM to practitioners. The curriculum was specifically helpful for training surgeons with less upper-GI endoscopy experience.

The efficacy of methods like e-learning as a supplement to traditional face-to-face instruction needs to be evaluated in dental courses. This study aimed to assess the efficacy of posting case presentations on one of the educational websites of  the virtual school of Tehran University of Medical Sciences called "SARMAD" to enhance the ability of senior dental students to diagnose tooth discolorations and offer treatment plans. This experimental study had a pre-test/post-test control group design and was conducted on 63 senior dental students. After filling out the primary questionnaire and obtaining a written informed consent, students participated in a pre-test and were then randomly divided into two groups of intervention and control. Fifteen case presentations were posted on the university website (SARMAD) during 6 weeks and discussed. Then, students participated in a post-test. Students' perspectives and their satisfaction with the website were assessed by a questionnaire. For ethical purposes, the same program was also offered to the controls. The post-test score was significantly higher than the pre-test score in the intervention group (P<0.001); but in the control group, the post-test score was only slightly higher than the pre-test score (P=0.128). In the intervention group, 70% stated that they would suggest this method as an efficient educational modality; 93.3% stated that this method would be beneficial as a supplement to conventional education; 16.7% ranked the SARMAD website excellent, 30% ranked it good, 33.3% acceptable, 16.7% moderate and 3.3 poor. It appears that this instructional modality may be efficiently used as a supplement to traditional instruction in undergraduate dental curricula.

Evidence suggests that stress-induced changes in testosterone and cortisol are related to future competitive behaviours and team-sport outcomes. Therefore, we examined whether salivary testosterone and cortisol reactivity to a mid-week stress test can discriminate a match outcome in international rugby union competition. Single group, quasi-experimental design with repeated measures. Thirty-three male rugby players completed a standardised stress test three or four days before seven international matches. Stress testing involved seven minutes of shuttle runs (2×20m), dispersed across one-minute stages with increasing speeds. Salivary testosterone and cortisol were measured in the morning, along with delta changes from morning to pre-test (Morn-PreΔ) and pre-test to post-test (Pre-PostΔ). Data were compared across wins (n=3) and losses (n=4). The Morn-PreΔ in cortisol increased before winning and decreased prior to losing (p<0.001), with a large effect size difference (d=1.6, 90% CI 1.3-1.9). Testosterone decreased significantly across the same period, irrespective of the match outcome. The Morn-PreΔ in testosterone and cortisol, plus the Pre-PostΔ in testosterone, all predicted a match outcome (p≤0.01). The final model showed good diagnostic accuracy (72%) with cortisol as the main contributor. The salivary testosterone and cortisol responses to mid-week testing showed an ability to discriminate a rugby match outcome over a limited number of games. The Morn-PreΔ in cortisol was the strongest diagnostic biomarker. This model may provide a unique format to assess team readiness or recovery between competitions, especially with the emergence of rapid hormonal testing. Copyright © 2017 Sports Medicine Australia.

Nurses need to be well prepared to address the needs of a diverse population and facilitate positive experiences in an equitable and inclusive approach to care. The aim of the study was to determine whether the integration of consumer lived experience interviews into the content of a first-year course influenced empathy in nursing students. A one group pre-test, post-test design was used. A convenience sample of first-year undergraduate nursing students (N = 32) from a regional Australian university was recruited for the study. The pre and post tests were conducted using the Kiersma Chen Empathy Scale and t-tests performed to analyse the data. Results showed overall that nursing students demonstrated moderate levels of empathy; pre-test score of (M = 75.53; SD = 5.76). After the intervention the post-test results showed that there was a statistically significant increase in students' empathy towards vulnerable, disadvantaged and stigmatised population groups. The healthcare consumer voice has the potential to strengthen current teaching practices that promote caring behaviours in nursing students. Copyright © 2017 Elsevier Ltd. All rights reserved.

2005-01-01

Objective: To assess the impact of clinicians' use of an online information retrieval system on their performance in answering clinical questions. Design: Pre-/post-intervention experimental design. Measurements: In a computer laboratory, 75 clinicians (26 hospital-based doctors, 18 family practitioners, and 31 clinical nurse consultants) provided 600 answers to eight clinical scenarios before and after the use of an online information retrieval system. We examined the proportion of correct answers pre- and post-intervention, direction of change in answers, and differences between professional groups. Results: System use resulted in a 21% improvement in clinicians' answers, from 29% (95% confidence interval [CI] 25.4–32.6) correct pre- to 50% (95% CI 46.0–54.0) post-system use. In 33% (95% CI 29.1–36.9) answers were changed from incorrect to correct. In 21% (95% CI 17.1–23.9) correct pre-test answers were supported by evidence found using the system, and in 7% (95% CI 4.9–9.1) correct pre-test answers were changed incorrectly. For 40% (35.4–43.6) of scenarios, incorrect pre-test answers were not rectified following system use. Despite significant differences in professional groups' pre-test scores [family practitioners: 41% (95% CI 33.0–49.0), hospital doctors: 35% (95% CI 28.5–41.2), and clinical nurse consultants: 17% (95% CI 12.3–21.7; χ2 = 29.0, df = 2, p < 0.01)], there was no difference in post-test scores. (χ2 = 2.6, df = 2, p = 0.73). Conclusions: The use of an online information retrieval system was associated with a significant improvement in the quality of answers provided by clinicians to typical clinical problems. In a small proportion of cases, use of the system produced errors. While there was variation in the performance of clinical groups when answering questions unaided, performance did not differ significantly following system use. Online information retrieval systems can be an effective tool in improving the accuracy of clinicians' answers to clinical questions. PMID:15684126

2018-02-01

Simulation-based programs are increasingly being used to teach obstetrics and gynaecology examinations, but it is difficult to establish student learning acquired through them. Assessment may test student learning but its role in learning itself is rarely recognised. We undertook this study to assess medical and midwifery student learning through a simulation program using a pre-test and post-test design and also to evaluate use of assessment as a method of learning. The interprofessional simulation education program consisted of a brief pre-reading document, a lecture, a video demonstration and a hands-on workshop. Over a 24-month period, 405 medical and 104 midwifery students participated in the study and were assessed before and after the program. Numerical data were analysed using paired t-test and one-way analysis of variance. Students' perceptions of the role of assessment in learning were qualitatively analysed. The post-test scores were significantly higher than the pre-test (P < 0.001) with improvements in scores in both medical and midwifery groups. Students described the benefit of assessment on learning in preparation of the assessment, reinforcement of learning occurring during assessment and reflection on performance cementing previous learning as a post-assessment effect. Both medical and midwifery students demonstrated a significant improvement in their test scores and for most students the examination process itself was a positive learning experience. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Wang, Jing-Jy; Hsu, Ya-Chuan; Cheng, Su-Fen

2005-01-01

This study examined the effects of reminiscence on four selected mental health indicators, including depressive symptoms, mood status, self-esteem, and self-health perception of elderly people residing in community care facilities and at home. A longitudinal quasi-experimental design was conducted, using two equivalent groups for pre-post test and purposive sampling with random assignment. Each subject was administered pre- and post- tests at a 4 month interval but subjects in the experimental group underwent weekly intervention. Ninety-four subjects completed the study, with 48 in the control group and 46 in the experimental group. In the experimental group, a statistically significant difference (p = 0.041) was found between the pre-post tests on the dependent variable, depressive symptoms. However, no statistical significance was found in subjects' level of mood status, self-esteem, and self-health perception after the intervention in the experimental group, but slightly improvement was found. Reminiscence not only supports depression of the elderly but also empower nurses to become proactive in their daily nursing care activities.

Vázquez-Alonso, Ángel; Aponte, Abdiel; Manassero-Mas, María-Antonia; Montesano, Marisa

2016-07-01

This study examines the effectiveness of a teaching-learning sequence (TLS) to improve the understanding of the influences and interactions between a technology (mining) and society. The aim of the study is also to show the possibility of both teaching and assessing the most innovative issues and aspects of scientific competence and their impact on the understanding of the nature of science. The methodology used a quasi-experimental, pre-post-test design with a control group, with pre-post-test differences as the empirical indicators of improved understanding. Improvements were modest, as the empirical differences (pre-post and experimental-control group) were not large, but the experimental group scored more highly than the control group. The areas that showed improvement were identified. The paper includes the TLS itself and the standardized assessment tools that are functional and transferable to other researchers and teachers.

2017-12-01

This study implemented two pedagogical strategies, the Thinking Aloud Pair Problem Solving and Pólya’s Problem Solving, to support students’ learning of fractions. The participants were 51 students (ages 11-13) from two Year 7 classes in a government secondary school in Brunei Darussalam. A mixed method design was employed in the present study, with data collected from the pre- and post-tests, problem solving behaviour questionnaire and interviews. The study aimed to explore if there were differences in the students’ problem solving behaviour before and after the implementation of the problem solving strategies. Results from the Wilcoxon Signed Rank Test revealed a significant difference in the test results regarding student problem solving behaviour, z = -3.68, p = .000, with a higher mean score for the post-test (M = 95.5, SD = 13.8) than for the pre-test (M = 88.9, SD = 15.2). This implied that there was improvement in the students’ problem solving performance from the pre-test to the post-test. Results from the questionnaire showed that more than half of the students increased scores in all four stages of the Pólya’s problem solving strategy, which provided further evidence of the students’ improvement in problem solving.

Cryotherapy, in the form of ice massge is used to reduce inflammation after acute musculoskeletal injury or trauma. The potential negative effects of ice massage on proprioception are unknown, despite equivocal evidence supporting its effectiveness. The purpose of the study was to test the influence of cooling on weight discrimination ability and hence the performance in footballers. The study was of same subject experimental design (pretest-posttest design). Thirty male collegiate football players, whose mean age was 21.07 years, participated in the study. The participants were assessed for two functional performance tests, single leg hop test and crossed over hop test and weight discrimination ability before and after ice massage for 5 minutes on hamstrings muscle tendon. Pre cooling scores of Single Leg Hop Test of the dominant leg in the subjects was 166.65 (± 10.16) cm and post cooling scores of the dominant leg was 167.25 (± 11.77) cm. Pre cooling scores of Crossed Over Hop Test of the dominant leg in the subjects was 174.14 (± 8.60) cm and post cooling scores of the dominant leg was 174.45 (± 9.28) cm. Pre cooling scores of Weight Discrimination Differential Threshold of the dominant leg in the subjects was 1.625 ± 1.179 kg compared with post cooling scores of the dominant leg 1.85 (± 1.91) kg. Pre cooling scores of single leg hop and crossed over hop test of the dominant leg in the subjects compared with post cooling scores of the dominant leg showed no significant differences and it was also noted that the weight discrimination ability (weight discrimination differential threshold) didn't show any significant difference. All the values are reported as mean ± SD. This study provides additional evidence that proprioceptive acuity in the hamstring muscles (biceps femoris) remains largely unaffected after ice application to the hamstrings tendon (biceps femoris).

Dependent sample t-test for "how often do nurses feel stressed a work in a typical week" revealed pre-survey mean 2.97 (SD=0.99) which was significantly higher than post-survey mean 2.70 (SD=0.92) with significance, t(69)=2.36, p=0.021, suggesting a difference in how often staff felt stressed at work in a typical week, trending down from "feeling stressed half of time" to "once in a while". There were no statistically significant differences in pre-post survey scores for TICU, TOU, or SSC as separate units. Use of essential oils to decrease work-related stress among nursing staff may improve retention, workplace environment, and increase nurse satisfaction. Copyright © 2017 Elsevier Ltd.

Nursing student evaluation of NIOSH workplace violence prevention for nurses online course.

PubMed

Brann, Maria; Hartley, Dan

2017-02-01

As primary targets of workplace violence in health care settings, nurses may suffer negative physical and psychological consequences. NIOSH created an online course to educate nurses about violence prevention techniques. A mixed-methods approach assessed workplace violence awareness and knowledge among nursing students. A pre/post/post-test survey and focus group discussions evaluated participant awareness and knowledge, assessed course design, and solicited recommendations for increasing participation and strategies for improving message retention. The mean awareness scores differed significantly between pre-course and both post-course time points (Wilk's λ=0.319, F(2, 46)=49.01, p<0.001). Post hoc tests using the Bonferroni correction revealed that course participation increased awareness of workplace violence from pre-course scores (M=0.75, SD=0.438) to immediate post-course (M=2.13, SD=0.789) and four-week post-course (M=1.96, SD=0.771) scores on a 3-item measure. Similarly, mean knowledge scores increased between pre-course and both post-course time points (Wilk's λ=0.495, F(1.57, 73.66)=37.26, p<0.001). Post hoc tests using the Bonferroni correction revealed that course participation increased knowledge of workplace violence from pre-course scores (M=6.65, SD=1.45) to immediate post-course (M=8.56, SD=1.32) and four-week post-course (M=8.19, SD=1.42) scores on a 10-item measure. Qualitative data from the focus groups reinforced the quantitative findings. Participants citing benefits from the content strongly recommended including the course in nursing curriculums. Incorporating the course early in the nursing educational experience will better prepare students to deal with workplace violence when they enter health care professions. The results indicate that NIOSH and its partners created an effective online workplace violence awareness and prevention course. Practical applications: Nursing students and professionals can be effectively educated about workplace violence using an online format. Copyright © 2016 National Safety Council and Elsevier Ltd.

Leisure education reduces stress among older adults.

PubMed

Chang, Liang-Chih

2014-01-01

The objectives of this study were to examine whether a leisure education program could facilitate leisure competence among older adults and whether it could also reduce their stress. A pre-test-post-test randomized experimental design was conducted. Subjects were randomly assigned to either an experimental group (n = 30) or a control group (n = 30). A leisure education program was used to serve as the intervention. A day before this experiment was carried out, pre-test data were collected using leisure competence and stress scales. Thirty minutes after this experiment ended, post-test data were collected using the same scales. These data were analyzed using an analysis of covariance. The results indicated that the average post-test scores of leisure competence in the experimental group were significantly higher than those in the control group and that the average post-test scores of stress in the experimental group were significantly lower than those in the control group. Healthcare practitioners should adopt the provision of leisure education as a priority to facilitate leisure competence and reduce stress among older adults.

The aim of this study was to investigate the effectiveness of the harm reduction group therapy based on Bandura's self-efficacy theory on risky behaviors of sex workers in Kerman, Iran. A quasi-experimental two-group design (a random selection with pre-test and post-test) was used. A risky behaviors questionnaire was used to collect. The sample was selected among sex workers referring to drop-in centers in Kerman. Subjects were allocated to two groups and were randomly classified into two experimental and control groups. The sample group consisted of 56 subjects. The experimental design was carried out during 12 sessions, and the post-test was performed one month and two weeks after the completion of the sessions. The results were analyzed statistically. By reducing harm based on Bandura's self-efficacy theory, the risky behaviors of the experimental group, including injection behavior, sexual behavior, violence, and damage to the skin, were significantly reduced in the pre-test compared to the post-test (P < 0.010). The harm reduction group therapy based on Bandura's self-efficacy theory can reduce the risky behaviors of sex workers.

[Cancer nursing care education programs: the effectiveness of different teaching methods].

Cheng, Yun-Ju; Kao, Yu-Hsiu

2012-10-01

In-service education affects the quality of cancer care directly. Using classroom teaching to deliver in-service education is often ineffective due to participants' large workload and shift requirements. This study evaluated the learning effectiveness of different teaching methods in the dimensions of knowledge, attitude, and learning satisfaction. This study used a quasi-experimental study design. Participants were cancer ward nurses working at one medical center in northern Taiwan. Participants were divided into an experimental group and control group. The experimental group took an e-learning course and the control group took a standard classroom course using the same basic course material. Researchers evaluated the learning efficacy of each group using a questionnaire based on the quality of cancer nursing care learning effectiveness scale. All participants answered the questionnaire once before and once after completing the course. (1) Post-test "knowledge" scores for both groups were significantly higher than pre-test scores for both groups. Post-test "attitude" scores were significantly higher for the control group, while the experimental group reported no significant change. (2) after a covariance analysis of the pre-test scores for both groups, the post-test score for the experimental group was significantly lower than the control group in the knowledge dimension. Post-test scores did not differ significantly from pre-test scores for either group in the attitude dimension. (3) Post-test satisfaction scores between the two groups did not differ significantly with regard to teaching methods. The e-learning method, however, was demonstrated as more flexible than the classroom teaching method. Study results demonstrate the importance of employing a variety of teaching methods to instruct clinical nursing staff. We suggest that both classroom teaching and e-learning instruction methods be used to enhance the quality of cancer nursing care education programs. We also encourage that interactivity between student and instructor be incorporated into e-learning course designs to enhance effectiveness.

2011-01-01

To assess the prognostic significance of pre-operative electrophysiological tests for facial nerve outcome in vestibular schwannoma surgery. Retrospective study design in a tertiary referral neurology unit. We studied a total of 123 patients with unilateral vestibular schwannoma who underwent microsurgical removal of the lesion. Nine patients were excluded because they had clinically abnormal pre-operative facial function. Pre-operative electrophysiological facial nerve function testing (EPhT) was performed. Short-term (1 month) and long-term (1 year) post-operative clinical facial nerve function were assessed. When pre-operative facial nerve function, evaluated by EPhT, was normal, the outcome from clinical follow-up at 1-month post-operatively was excellent in 78% (i.e. HB I-II) of patients, moderate in 11% (i.e. HB III-IV), and bad in 11% (i.e. HB V-VI). After 1 year, 86% had excellent outcomes, 13% had moderate outcomes, and 1% had bad outcomes. Of all patients with normal clinical facial nerve function, 22% had an abnormal EPhT result and 78% had a normal result. No statistically significant differences could be observed in short-term and long-term post-operative facial function between the groups. In this study, electrophysiological tests were not able to predict facial nerve outcome after vestibular schwannoma surgery. Tumour size remains the best pre-operative prognostic indicator of facial nerve function outcome, i.e. a better outcome in smaller lesions.

2012-01-01

This pilot study compared the clinical endpoints of the magnetostrictive and piezoelectric ultrasonic instruments on calculus removal. The null hypothesis stated that there is no statistically significant difference in calculus removal between the 2 instruments. A quasi-experimental pre- and post-test design was used. Eighteen participants were included. The magnetostrictive and piezoelectric ultrasonic instruments were used in 2 assigned contra-lateral quadrants on each participant. A data collector, blind to treatment assignment, assessed the calculus on 6 predetermined tooth sites before and after ultrasonic instrumentation. Calculus size was evaluated using ordinal measurements on a 4 point scale (0, 1, 2, 3). Subjects were required to have size 2 or 3 calculus deposit on the 6 predetermined sites. One clinician instrumented the pre-assigned quadrants. A maximum time of 20 minutes of instrumentation was allowed with each technology. Immediately after instrumentation, the data collector then conducted the post-test calculus evaluation. The repeated analysis of variance (ANOVA) was used to analyze the pre- and post-test calculus data (p≤0.05). The null hypothesis was accepted indicating that there is no statistically significant difference in calculus removal when comparing technologies (p≤0.05). Therefore, under similar conditions, both technologies removed the same amount of calculus. This research design could be used as a foundation for continued research in this field. Future studies include implementing this study design with a larger sample size and/or modifying the study design to include multiple clinicians who are data collectors. Also, deposit removal with periodontal maintenance patients could be explored.

This study aimed to evaluate changes in evidence-based practice (EBP) knowledge, attitudes, and practice of nursing students before and after completing an online, graduate level, introductory research/EBP course. A prospective one-group pretest-posttest design. A private university in the Midwestern, USA. Sixty-three online nurse practitioner students in Master's program. A convenient sample of online graduate nursing students who enrolled in the research/EBP course was invited to participate in the study. Study outcomes were measured using the Evidence-Based Practice Questionnaire (EBPQ) before and after completing the course. Descriptive statistics and paired-Samples t-test was used to assess the mean differences between pre-and post-test scores. Overall, students' post-test EBP scores were significantly improved over pre-test scores, t(63)=-9.034, p<0.001). Statistically significant differences were found for practice of EBP mean scores t(63)=-12.78, p=0.001). No significant differences were found between pre and post-tests on knowledge and attitudes toward EBP scores. Most frequently cited barriers to EBP were lack of understanding of statistics, interpretation of findings, lack of time, and lack of library resources. Copyright © 2017 Elsevier Ltd.

Effect of a brief cognitive behavioural intervention on criminal thinking and prison misconduct in male inmates: Variable-oriented and person-oriented analyses.

PubMed

Walters, Glenn D

2017-12-01

There is some consensus on the value of cognitive-behaviourally informed interventions in the criminal justice system, but uncertainty about which components are of critical value. To test the hypothesis that change in prisoners - criminal thinking and institutional misconduct - will both follow completion of a brief cognitive behavioural intervention. A one-group pre-test-post-test quasi-experimental design was used to assess change on the General Criminal Thinking (GCT) scale of the Psychological Inventory of Criminal Thinking Styles among 219 male prisoners completing a 10-week cognitive behavioural intervention, referred to as 'Lifestyle Issues'. Institutional misconduct was measured for 1 year prior to completion of the course and 2 years subsequently. Using variable-oriented analysis, post-test GCT scores were compared with change in prison conduct, controlling for the pre-test thinking scores. Calculations were repeated by using person-oriented analysis. Prisoners who displayed a drop in GCT scores between pre-test and post-test levels were significantly more likely to show a reduction in prison misconduct, whereas prison misconduct was likely to escalate among those who displayed a rise in criminal thinking scores from pre-test to post-test. These findings must still be regarded as preliminary, but taken together with other work and with cognitive behavioural theory, they suggest that development of more prosocial thinking and abilities may have an early beneficial effect on institutional behaviour. Their measurement may offer a practical way in which men could be assessed for readiness to return to the community. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

Discrimination and distress among Afghan refugees in northern California: The moderating role of pre- and post-migration factors

PubMed Central

2018-01-01

This study investigates the effect of perceived discrimination on the mental health of Afghan refugees, and secondly, tests the distress moderating effects of pre-migration traumatic experiences and post-resettlement adjustment factors. In a cross-sectional design, 259 Afghans completed surveys assessing perceived discrimination and a number of other factors using scales developed through inductive techniques. Multivariable analyses consisted of a series of hierarchical regressions testing the effect of perceived discrimination on distress, followed by a sequential analysis of moderator variables. Perceived discrimination was significantly associated with higher distress, and this relationship was stronger among those with a strong intra-ethnic identity and high pre-resettlement traumatic experiences. The expected buffering effects of civic engagement, ethnic orientation (e.g. integration), and social support were not significant. Discrimination is a significant source of stress for Afghan refugees, which may exacerbate stresses associated with other pre- and post-migration stressors. Future research is needed to tailor interventions that can help mitigate the stress associated with discrimination among this highly vulnerable group. PMID:29782531

Pre-launch calibration and algorithm design for the GOES Geostationary Lightning Mapper resulted in a successful and trouble-free on-orbit activation and post-launch test sequence. Within minutes of opening the GLM aperture door on January 4th, 2017, lightning was detected across the entire field of view. During the six-month post-launch test period, numerous processing parameters on board the instrument and in the ground processing algorithms were fine-tuned. Demonstrated on-orbit performance exceeded pre-launch predictions. We provide an overview of the ground calibration sequence, on-orbit tuning of the instrument, tuning of the ground processing algorithms (event filtering and navigation). We also touch on new insights obtained from analysis of a large and growing archive of raw GLM data, containing 3e8 flash detections derived from over 1e10 full-disk images of the Earth.

This study aimed to evaluate the effect of an anti-bullying intervention programme on peers' attitudes towards bullying and their attempts to solve bully/victim conflicts. An experimental pre-test/post-test design with a control group was used. For secondary school students, positive outcomes were observed at post-test 1 on attitudes and on actual rates of intervention. However, the effects had disappeared at post-test 2. For primary school students, significant differences were found at post-test 2, showing a smaller decline in seeking teacher's help and in heightening students' support for victims. Students' competence to solve bully/victim problems in relation to their general pro-social development is discussed. Copyright 2000 The Association for Professionals in Services for Adolescents.

2015-09-01

To examine youth exposure to smoking in cars following 7 provincial bans on smoking in cars with children in Canada. Repeated cross-sectional data from the 2004-2012 Youth Smoking Survey (n=91,800) were examined. Using a quasi-experimental design, contrasts of the interaction of survey year and province included in the logistic regression analyses were used to test whether exposure significantly declined pre-post implementation of a ban on smoking in cars relative to control provinces not implementing a ban. Exposure across all provinces declined from 26.5% in 2004 to 18.2% of youth in 2012. Exposure declined significantly from pre to post implementation of a ban on smoking in cars with children in Ontario at time 1 post ban (Pre-Ban=20.4% T1post=10.3%, OR=0.45), time 2 post ban (12.1%, OR=0.61) and time 3 post ban (11.6%, OR=0.58) relative to control provinces that did not implement a ban. In British Columbia exposure to smoking in cars declined significantly at pre-post ban time 3 compared to the control group (Pre-Ban=21.2%, T3post=9.6%, OR=0.51). No other provinces had a significant change in exposure pre-post ban relative to the control provinces. Although rates declined, significant differences were only found in Ontario relative to control provinces in the immediate and long term. Copyright © 2015 Elsevier Inc. All rights reserved.

This study examined a gratitude intervention repeating Emmons and McCullough study (2003) in a Spanish sample, Participants were randomly assigned to one of three conditions (gratitude, hassles and any event) and kept daily records during 2 weeks of gratitude, affect, quality of relationships, physical and subjective well-being. We added design features to assess the intervention long-term impact (follow-up measures), and to improve the design control (pre-treatment measures). Following the cited authors' analysis, i.e., comparing groups only in the post-test, we replicated their results, finding differences in positive affect and gratitude between the gratitude condition and the hassles condition. However, when including both the pre and the follow-up measures in the analysis, results were replicated only partially, as the difference in gratitude disappeared. Moreover, the difference in positive affect between groups in the post-test seemed to be influenced mainly by a decrease in positive affect in the hassles group. Post-test differences between groups in positive affect disappeared in the follow-up. Gratitude interventions may have an effect on well-being, but we consider other methods to promote gratitude besides gratitude journals should be tested.

2015-07-01

Poorly designed experiments and popular media have led to multiple myths about wound ballistics. Some of these myths have been incorporated into the trauma literature as fact and are included in Advanced Trauma Life Support (ATLS). We hypothesized that these erroneous beliefs would be prevalent, even among those providing care for patients with gunshot wounds (GSWs), but could be addressed through education. ATLS course content was reviewed. Several myths involving wound ballistics were identified. Clinically relevant myths were chosen including wounding mechanism, lead poisoning, debridement, and antibiotic use. Subsequently, surgery and emergency medicine services at three different trauma centers were studied. All three sites were busy, urban trauma centers with a significant amount of penetrating trauma. A pre-test was administered prior to a lecture on wound ballistics followed by a post-test. Pre- and post-test scores were compared and correlated with demographic data including ATLS course completion, firearm/ballistics experience, and years of post-graduate medical experience (PGME). One-hundred and fifteen clinicians participated in the study. A mean pre-test score of 34 % improved to 78 % on the post-test with associated improvements in all areas of knowledge (p < 0.001). Years of PGME correlated with higher pre-test score (p = 0.021); however, ATLS status did not (p = 0.774). Erroneous beliefs involving wound ballistics are prevalent even among clinicians who frequently treat victims of GSWs and could lead to inappropriate treatment. Focused education markedly improved knowledge. The ATLS course and manual promulgate some of these myths and should be revised.

Abstract Background Empathic concern has been found to decline in health professional students. Few effective educational programs and a lack of validated scales are reported. Previous analysis of the Empathic Concern scale of the Emotional Response Questionnaire has reported both one and two latent constructs. Aim To evaluate the impact of simulation on nursing students' empathic concern and test the psychometric properties of the Empathic Concern scale. Methods The study used a one group pre-test post-test design with a convenience sample of 460 nursing students. Empathic concern was measured pre-post simulation with the Empathic Concern scale. Factor Analysis was undertaken to investigate the structure of the scale. Results There was a statistically significant increase in Empathic Concern scores between pre-simulation 5.57 (SD = 1.04) and post-simulation 6.10 (SD = 0.95). Factor analysis of the Empathic Concern scale identified one latent dimension. Conclusion Immersive simulation may promote empathic concern. The Empathic Concern scale measured a single latent construct in this cohort.

To compare high-fidelity simulation with case-based discussion for teaching medical students about pediatric emergencies, as assessed by a knowledge post-test, a knowledge retention test and a survey of satisfaction with the method. This was a non-randomized controlled study using a crossover design for the methods, as well as multiple-choice questionnaire tests and a satisfaction survey. Final-year medical students were allocated into two groups: group 1 participated in an anaphylaxis simulation and a discussion of a supraventricular tachycardia case, and conversely, group 2 participated in a discussion of an anaphylaxis case and a supraventricular tachycardia simulation. Students were tested on each theme at the end of their rotation (post-test) and 4-6 months later (retention test). Most students (108, or 66.3%) completed all of the tests. The mean scores for simulation versus case-based discussion were respectively 43.6% versus 46.6% for the anaphylaxis pre-test (p=0.42), 63.5% versus 67.8% for the post-test (p=0.13) and 61.5% versus 65.5% for the retention test (p=0.19). Additionally, the mean scores were respectively 33.9% versus 31.6% for the supraventricular tachycardia pre-test (p=0.44), 42.5% versus 47.7% for the post-test (p=0.09) and 41.5% versus 39.5% for the retention test (p=0.47). For both themes, there was improvement between the pre-test and the post-test (p<0.05), and no significant difference was observed between the post-test and the retention test (p>0.05). Moreover, the satisfaction survey revealed a preference for simulation (p<0.001). As a single intervention, simulation is not significantly different from case-based discussion in terms of acquisition and retention of knowledge but is superior in terms of student satisfaction.

To determine whether general practitioners learned better with task-based learning or problem-oriented lecture in a Continuing Medical Education (CME) set-up. Quasi-experimental study. The Aga Khan University, Karachi campus, from April to June 2012. Fifty-nine physicians were given a choice to opt for either Task-based Learning (TBL) or Problem Oriented Lecture (PBL) in a continuing medical education set-up about headaches. The TBL group had 30 participants divided into 10 small groups, and were assigned case-based tasks. The lecture group had 29 participants. Both groups were given a pre and a post-test. Pre/post assessment was done using one-best MCQs. The reliability coefficient of scores for both the groups was estimated through Cronbach's alpha. An item analysis for difficulty and discriminatory indices was calculated for both the groups. Paired t-test was used to determine the difference between pre- and post-test scores of both groups. Independent t-test was used to compare the impact of the two teaching methods in terms of learning through scores produced by MCQ test. Cronbach's alpha was 0.672 for the lecture group and 0.881 for TBL group. Item analysis for difficulty (p) and discriminatory indexes (d) was obtained for both groups. The results for the lecture group showed pre-test (p) = 42% vs. post-test (p) = 43%; pre- test (d) = 0.60 vs. post-test (d) = 0.40. The TBL group showed pre -test (p) = 48% vs. post-test (p) = 70%; pre-test (d) = 0.69 vs. post-test (d) = 0.73. Lecture group pre-/post-test mean scores were (8.52 ± 2.95 vs. 12.41 ± 2.65; p < 0.001), where TBL group showed (9.70 ± 3.65 vs. 14 ± 3.99; p < 0.001). Independent t-test exhibited an insignificant difference at baseline (lecture 8.52 ± 2.95 vs. TBL 9.70 ± 3.65; p = 0.177). The post-scores were not statistically different lecture 12.41 ± 2.65 vs. TBL 14 ± 3.99; p = 0.07). Both delivery methods were found to be equally effective, showing statistically insignificant differences. However, TBL groups' post-test higher mean scores and radical increase in the post-test difficulty index demonstrated improved learning through TBL delivery and calls for further exploration of longitudinal studies in the context of CME.

Lachapelle, Ugo; Noland, Robert B; Von Hagen, Leigh Ann

2013-03-01

There are multiple health and environmental benefits associated with increasing bicycling among children. However, the use of bicycles is also associated with severe injuries and fatalities. In order to reduce bicycle crashes, a bicycling education program was implemented in selected New Jersey schools and summer camps as part of the New Jersey Safe Routes to School Program. Using a convenience sample of participants to the program, an opportunistic study was designed to evaluate the effectiveness of two bicycle education programs, the first a more-structured program delivered in a school setting, with no on-road component, and the other a less structured program delivered in a summer camp setting that included an on-road component. Tests administered before and after training were designed to assess knowledge acquired during the training. Questions assessed children's existing knowledge of helmet use and other equipment, bicycle safety, as well as their ability to discriminate hazards and understand rules of the road. Participating children (n=699) also completed a travel survey that assessed their bicycling behavior and their perception of safety issues. Response to individual questions, overall pre- and post-training test scores, and changes in test scores were compared using comparison of proportion, t-tests, and ordinary least-squares (OLS) regression. Improvements between the pre-training and post-training test are apparent from the frequency distribution of test results and from t-tests. Both summer camps and school-based programs recorded similar improvements in test results. Children who bicycled with their parents scored higher on the pre-training test but did not improve as much on the post-training test. Without evaluating long-term changes in behavior, it is difficult to ascertain how successful the program is on eventual behavioral and safety outcomes. Copyright © 2012 Elsevier Ltd.

To assess knowledge, attitude and practice (KAP) of healthcare staff regarding pharmaceutical waste management; and to determine the impact of an educational programme on the KAP survey items. Pre-post-test intervention study. The pre-intervention phase was performed using a sample of 530 out of 1500 healthcare workers. A predesigned interview questionnaire was used to assess KAP. Next, an educational programme was designed and offered to a subsample of 69 healthcare workers. KAP were re-assessed for the programme attendees using the same interview questionnaire, both immediately (post-test) and six months after the end of the programme (follow-up test). The parametric paired sample t-test was used to assess the difference between pre-test and follow-up test results. Poor knowledge and poor practice levels (scores 50%) detected in the pre-intervention phase were found to improve to satisfactory levels (scores ≥75%) in the follow-up phase. Attitude was found to be positive (score ≥75%) in all phases of the study. The educational programme led to a significant improvement in KAP of healthcare staff regarding pharmaceutical waste management (P<0.001). Copyright © 2016. Published by Elsevier Ltd.

2017-03-01

To assess the feasibility of characterizing and following up the mechanical behavior of the corneal tissue after corneal cross-linking (CXL) by using a combined mechanical (in vivo indentation and in vitro uniaxial tensile tests) and morphological (immunohisto-chemistry) experimental protocol. CXL (3 mW/cm 2 ; 370 nm) for 20 minutes (total dose 3.6 J/cm 2 ) was performed on 12 New Zealand rabbits. The mechanical behavior of the cornea was characterized in small and large strain regimens using an in vivo indentation test with a laboratory device and an in vitro uniaxial tensile test, respectively. These tests and corneal immunohistochemistry were performed before (PreCXL) and on the 7th (PostCXL-7d) and 56th days (PostCXL-56d) after CXL. The intraocular pressure and corneal thickness were measured before each test. For the indentation tests, significant differences were found between PreCXL and PostCXL-7d and between PostCXL-7d and PostCXL-56d, but not between PreCXL and PostCXL-56d. On average, for the small strain regimen, PostCXL-7d corneas showed the most compliant behavior, with progressive recovery of the corneal stiffness over time. For the large strain regimen, significant differences in the maximum tangent modulus between PreCXL and PostCXL-7d and between PreCXL and PostCXL-56d were observed for the uniaxial tensile tests, with no significant differences between PostCXL-7d and PostCXL-56d. Immunohistochemistry showed a lack of cells in the anterior stroma at PostCXL-7d, but at PostCXL-56d the cell density and morphology were comparable to PreCXL. Indentation tests cannot characterize the changes in the corneal collagen scaffold caused by the CXL, but the uniaxial test can. However, indentation tests can assess the recovery of keratocyte density after CXL. [J Refract Surg. 2017;33(3):184-192.]. Copyright 2017, SLACK Incorporated.

2012-01-01

Purpose To report findings on knowledge and skill acquisition following a 3-day training session in the use of short message service (SMS) texting with non- and low-literacy traditional midwives. Design A pre- and post-test study design was used to assess knowledge and skills acquisition with 99 traditional midwives on the use of SMS texting for real-time, remote data collection in rural Liberia, West Africa. Methods Paired sample t-tests were conducted to establish if overall mean scores varied significantly from pre-test to immediate post-test. Analysis of variance was used to compare means across groups. The nonparametric McNemar’s test was used to determine significant differences between the pre-test and post-test values of each individual step involved in SMS texting. Pearson’s chi-square test of independence was used to examine the association between ownership of cell phones within a family and achievement of the seven tasks. Findings The mean increase in cell phone knowledge scores was 3.67, with a 95% confidence interval ranging from 3.39 to 3.95. Participants with a cell phone in the family did significantly better on three of the seven tasks in the pre-test: “turns cell on without help” (χ2(1) = 9.15, p = .003); “identifies cell phone coverage” (χ2(1) = 5.37, p = .024); and “identifies cell phone is charged” (χ2(1) = 4.40, p = .042). Conclusions A 3-day cell phone training session with low- and nonliterate traditional midwives in rural Liberia improved their ability to use mobile technology for SMS texting. Clinical Relevance Mobile technology can improve data collection accessibility and be used for numerous healthcare and public health issues. Cell phone accessibility holds great promise for collecting health data in low-resource areas of the world. PMID:22672157

McCormack, Guy L

2009-01-01

The purpose of this study was to investigate the effects of non-contact therapeutic touch on post-surgical pain in an elderly population receiving occupational therapy in an acute care hospital unit in the United States. Ninety participants were randomly assigned to three groups (experimental, control and placebo) using a three-group experimental pre-test-post-test design and a randomized clinical trial. The experimental group received the non-contact touch intervention, the control group received routine care and the placebo group received the sound of a metronome set at a steady slow pace. Objective measures included the Memorial Pain Scale, the Tellegen Absorption Scale, the Health Attribution Scale and measures of pulse rate and pupil size, which were performed as repeated measures. In the experimental group, 22 out of 30 (73%) demonstrated a statistically significant decrease in pain intensity scores from pre-test to post-test (t [7] = 7.24, p < 0.01) and were better able to participate in occupations. Further research is recommended to replicate this study. 2009 John Wiley & Sons, Ltd

NASA Astrophysics Data System (ADS)

Diana, S.

2018-05-01

Research about the effect of Peer Assisted Learning (PAL) strategy on Plant Anatomy Course, which aims to improve anatomic competencies of prospective student’s biology teacher, has been done. This study used a quasi-experimental pre-test post-test control group design. The draft includes a group of students who were given a pre-test which is then followed by observing the PAL treatment process and post-test. The other students group (control) was given the pre-test and post-test only. The PAL program began with a discussion between the lecturer and the tutor about the pretest results and then discussion between the tutors and their tutees in the class about the responses items. After that, all students were assigned to answer a set of response items, and then did the posttest. The results showed that the PAL strategy can increase student’s anatomic literacy significantly and can increase student’s anatomic lab skills no significantly. Thus the PAL strategy implementation has a potential to improve student’s anatomic competencies. The generally students weaknesses were they lack practice in interpreting of research results in the graphs form and rarely shared about anatomic lab skills. All students respond positively to the PAL strategy.

Variable approaches to genetic counseling for microarray regions of homozygosity associated with parental relatedness.

PubMed

Grote, Lauren; Myers, Melanie; Lovell, Anne; Saal, Howard; Sund, Kristen Lipscomb

2014-01-01

SNP microarrays are capable of detecting regions of homozygosity (ROH) which can suggest parental relatedness. This study was designed to describe pre- and post-test counseling practices of genetics professionals regarding ROH, explore perceived comfort and ethical concerns in the follow-up of such results, demonstrate awareness of laws surrounding duty to report consanguinity and incest, and allow respondents to share their personal experiences with results suggesting a parental relationship. A 35 question survey was administered to 240 genetic counselors and geneticists who had ordered or counseled for SNP microarray. The results are presented using descriptive statistics. There was variation in both pre- and post-test counseling practices of genetics professionals. Twenty-five percent of respondents reported pre-test counseling that ROH can indicate parental relatedness. The most commonly reported ethical concern was disclosure of findings suggesting parental relatedness to parents of the patient; only 48.4% reported disclosing parental relatedness when indicated. Fifty-seven percent felt comfortable receiving results suggesting parental consanguinity while 17% felt comfortable receiving results suggesting parental incest. Twenty percent of respondents were extremely/moderately familiar with the laws about duty to report incest. Personal experiences in post-test counseling included both parental acknowledgement and denial of relatedness. This study highlights the differences in genetics professionals' pre- and post-test counseling practices, comfort, and experiences surrounding parental relatedness suggested by SNP microarray results. It identifies a need for professional organizations to offer guidance to genetics professionals about how to respond to and counsel for molecular results suggesting parental consanguinity or incest. © 2013 Wiley Periodicals, Inc.

Feasibility of using the patient-reported outcomes measurement information system in academic health centers: case series design on pain reduction after chiropractic care.

PubMed

Burke, Jeanmarie R

2014-09-01

The purpose of this study was to test the utility of Patient-Reported Outcomes Measurement Information System (PROMIS) as a resource for collecting data on patient-reported outcomes (PRO) within academic health centers at a chiropractic college; and, to describe changes in PRO following pragmatic chiropractic care incorporating instrument-assisted soft tissue mobilization (IASTM) on pain symptoms. This was a pre-post intervention design without a control group (case series) involving 25 patients (14 females and 11 males; 40.5 ± 16.39 years, range 20-70 years) who completed their chiropractic care and their baseline and post-treatment pain assessments. The pragmatic chiropractic care intervention included both spinal manipulation and IASTM to treat pain symptoms. PRO's were collected using PROMIS to measure pain behavior, pain interference and pain intensity. The average pre-post assessment interval was 33 ± 22.5 days (95% CI, 23-42 days). The durations of treatments ranged from one week to 10 weeks. The median number of IASTM treatments was six. Pre-post decreases in T-scores for pain behavior and pain interference were 55.5 to 48.4 and 57.7 to 48.4, respectively (P < .05). Only 12 patients had a baseline T-score for pain intensity greater than 50. The pre-post decrease in pain intensity T-scores for these 12 patients was from 53.4 to 40.9. Within the limitations of a case series design, these data provide initial evidence on the utility of PROMIS instruments for clinical and research outcomes in chiropractic patients.

Reality-based practice under pressure improves handgun shooting performance of police officers.

PubMed

Oudejans, R R D

2008-03-01

The current study examined whether reality-based practice under pressure may help in preventing degradation of handgun shooting performance under pressure for police officers. Using a pre-post-test design, one group of nine police officers practised handgun shooting under pressure evoked by an opponent who also fired back using marking (coloured soap) cartridges. The control group (n = 8) practised handgun shooting on standard cardboard targets instead of real opponents. Within a fortnight after the pre-test, both groups received three training sessions of 1 h, in which each person fired a total of 72 rounds. During the pre- and post test each participant took 30 shots without pressure (cardboard targets) and 30 shots under additional pressure (with an opponent firing back). While during the pre-test both groups performed worse in front of an opponent firing back compared to the cardboard targets, after the training sessions shooting performance of the experimental group no longer deteriorated with an opponent while performance of the control group was equally harmed as during the pre-test. These results indicate that training exercises involving increased pressure can acclimatize shooting performance of ordinary police officers to those situations with elevated pressure that they may encounter during their police work.

2017-10-01

Purpose: The purpose of this study was to measure the change in levels of knowledge of providing culturally competent care and self-assessed cultural competence of senior level dental hygiene students after the implementation of an online cultural competence training module. Methods: Twenty-eight members of the senior class of 31 dental hygiene students (N=28) volunteered to participate in this IRB approved study at the Ohio State University School of Dentistry. The students took the online Inventory for Assessing the Process of Cultural Competence- Student Version (IAPCC-SV), to assess their self-perceived cultural competence. Upon completion of the pre-test, students then completed the United States Department of Health and Human Services (HHS) Office of Minority Health (OMH) Cultural Competency Program for Oral Health Professionals; a three-module online training program designed to measure increased knowledge of cultural competence. Three weeks following the initial pre-test and upon completion of the Cultural Competency Program for Oral Health Professionals online learning modules, students re-took the IAPCC-SV. Results: Twenty-eight senior dental hygiene students completed the IAPCC-SV pre-test, the OMH e-learning modules and the IAPCC-SV post-test. The average score on the pre-test was 55.14±7.54 and the average score on the post-test was 61.33±7.86. There was a significant difference in pre-test and post-test scores (p<0.001). There were also significant differences in the constructs of knowledge of cultural competence (p<0.001) and skill (p<0.001). Conclusion: The HHS OMH Cultural Competency Program for Oral Health Professionals was effective for increasing dental hygiene students' levels of knowledge of cultural competence.

The course of Technology and Material Testing prepare students with the ability to do a variety of material testing in the study of mechanical engineering. Students find it difficult to understand the materials to make them unable to carry out the material testing in accordance with the purpose of study. This happens because they knowledge is not adequately supported by the competence to find and construct learning experience. In this study, quasy experiment research method with pre-post-test with control group design was used. The subjects of the study were students divided in two groups; control and experiment with twenty-two students in each group. Study result: their grades showed no difference in between the pre-test or post-test in control group, but the difference in grade existed between the pre-test and post-test in experiment group. Yet, there is no significant difference in the study result on both groups. The researcher recommend that it is necessary to develop Problem-Based Learning that suits need analysis on D3 Program for Mechanical Engineering Department at the State University of Padang, to ensure the compatibility between Model of Study and problems and need. This study aims to analyze how Problem-Based Learning effects on the course of Technology and Material Testing for the students of D3 Program of Mechanical Engineering of the State University of Padang.

This study explored the retention of basic life support knowledge, self-efficacy, and chest compression performance among Thai nursing students at a university in Thailand. A one-group, pre-test and post-test design time series was used. Participants were 30 nursing students undertaking basic life support training as a care provider. Repeated measure analysis of variance was used to test the retention of knowledge and self-efficacy between pre-test, immediate post-test, and re-test after 3 months. A Wilcoxon signed-rank test was used to compare the difference in chest compression performance two times. Basic life support knowledge was measured using the Basic Life Support Standard Test for Cognitive Knowledge. Self-efficacy was measured using the Basic Life Support Self-Efficacy Questionnaire. Chest compression performance was evaluated using a data printout from Resusci Anne and Laerdal skillmeter within two cycles. The training had an immediate significant effect on the knowledge, self-efficacy, and skill of chest compression; however, the knowledge and self-efficacy significantly declined after post-training for 3 months. Chest compression performance after training for 3 months was positively retaining compared to the first post-test but was not significant. Therefore, a retraining program to maintain knowledge and self-efficacy for a longer period of time should be established after post-training for 3 months. Copyright © 2015 Elsevier Ltd.

Improved ICU design reduces acquisition of antibiotic-resistant bacteria: a quasi-experimental observational study

PubMed Central

2011-01-01

Introduction The role of ICU design and particularly single-patient rooms in decreasing bacterial transmission between ICU patients has been debated. A recent change in our ICU allowed further investigation. Methods Pre-move ICU-A and pre-move ICU-B were open-plan units. In March 2007, ICU-A moved to single-patient rooms (post-move ICU-A). ICU-B remained unchanged (post-move ICU-B). The same physicians cover both ICUs. Cultures of specified resistant organisms in surveillance or clinical cultures from consecutive patients staying >48 hours were compared for the different ICUs and periods to assess the effect of ICU design on acquisition of resistant organisms. Results Data were collected for 62, 62, 44 and 39 patients from pre-move ICU-A, post-move ICU-A, pre-move ICU-B and post-move ICU-B, respectively. Fewer post-move ICU-A patients acquired resistant organisms (3/62, 5%) compared with post-move ICU-B patients (7/39, 18%; P = 0.043, P = 0.011 using survival analysis) or pre-move ICU-A patients (14/62, 23%; P = 0.004, P = 0.012 on survival analysis). Only the admission period was significant for acquisition of resistant organisms comparing pre-move ICU-A with post-move ICU-A (hazard ratio = 5.18, 95% confidence interval = 1.03 to 16.06; P = 0.025). More antibiotic-free days were recorded in post-move ICU-A (median = 3, interquartile range = 0 to 5) versus post-move ICU-B (median = 0, interquartile range = 0 to 4; P = 0.070) or pre-move ICU-A (median = 0, interquartile range = 0 to 4; P = 0.017). Adequate hand hygiene was observed on 140/242 (58%) occasions in post-move ICU-A versus 23/66 (35%) occasions in post-move ICU-B (P < 0.001). Conclusions Improved ICU design, and particularly use of single-patient rooms, decreases acquisition of resistant bacteria and antibiotic use. This observation should be considered in future ICU design. PMID:21914222

How effective is visual communication to increase awareness of natural hazards and risks? To answer this research question, we developed a research design that was at the same time an experimental setting and an actual communication effort. Throughout the full length of the 2-years project held in the Ubaye valley (southeastern France), we collaborated with local and regional stakeholders (politicians and technicians). During a consultation phase, the communication context was determined, the audience of the project was defined and finally the testing activity-communication effort was determined. We were offered the opportunity to design an exhibition for the local public library. In a consultation phase that corresponded to the design of the exhibition, the stakeholders contributed to its content as well as helping with the funding of the exhibition. Finally, during the experimentation phase, the stakeholders participated in advertising the activity, gathering of participants and designing the scientific survey. In order to assess the effects of the exhibition on risk awareness, several groups of children, teenagers and adults were submitted to a research design, consisting of 1) a pre-test, 2) the visit of the exhibition and 3) a post-test similar to the pre-test. In addition, the children answered a second post-test 3 months after the visit. Close ended questions addressed the awareness indicators mentioned in the literature, i.e. worry level, previous experiences with natural hazards events, exposure to awareness raising, ability to mitigate/respond/prepare, attitude to risk, and demographics. In addition, the post-test included several satisfaction questions concerning the visual tools displayed in the exhibition. A statistical analysis of the changes between the pre- and post- tests (paired t-test, Wilcoxon signed-rank test and bootstrapping) allowed to verify whether the exhibition had an impact on risk awareness or not. In order to deduce which variable influenced the observed changes, an ordinal regression was performed. In addition, to deduce the attractiveness of each visual tool independently, the visitors' paths were tracked using RFID (Radio Frequency Identification) technique, from which their time spent around certain visuals could be assessed. While the process of creating an exhibition as a real communication effort and a testing activity will be discussed, the results of the experiment will be presented. In particular, we will show for which natural hazard the most awareness changes were measured and with which factors they are assessed. Moreover, the attractiveness of each visual tools will be presented.

Bipolar disorder (BD) and temporal lobe epilepsy (TLE) overlap in domains including epidemiology, treatment response, shared neurotransmitter involvement and temporal lobe pathology. Comparison of cognitive function in both disorders may indicate temporal lobe mediated processes relevant to BD. This systematic review examines neuropsychological test profiles in euthymic bipolar disorder type I (BD-I) and pre-surgical TLE and compares experimental designs used. A search of PubMed, PsychINFO, and Scopus using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted. Inclusion criteria were comparison group or pre- to post-surgical patients; reported neuropsychological tests; participants aged 18-60 years. Fifty six studies met criteria: 27 BD-I; 29 TLE. Deficits in BD-I compared to healthy controls (HC) were in executive function, attention span and verbal memory. Deficits in TLE compared to HC were in executive function and memory. In the pre- to post-surgical comparisons, verbal memory in left temporal lobe (LTL) and, less consistently, visuospatial memory in right temporal lobe (RTL) epilepsy declined following surgery. BD-I studies used comprehensive test batteries in well-defined euthymic patients compared to matched HC groups. TLE studies used convenience samples pre- to post-surgery, comparing LTL and RTL subgroups, few included comparisons to HC (5 studies). TLE studies typically examined a narrow range of known temporal lobe-mediated neuropsychological functions, particularly verbal and visuospatial memory. Both disorders exhibit deficits in executive function and verbal memory suggestive of both frontal and temporal lobe involvement. However, deficits in TLE are measured pre- to post-surgery and not controlled at baseline pre-surgery. Further research involving a head-to-head comparison of the two disorders on a broad range of neuropsychological tests is needed to clarify the nature and extent of cognitive deficits and potential overlaps.

2011-03-01

The present study examined the comparative effects of a prediction/discussion-based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi-experimental research design of the pre-test-post-test non-equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion-based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre-test, post-test, and delayed post-test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between-within subjects analysis of variance revealed that students in both prediction/discussion-based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group.

Development, implementation, and evaluation of a mental rehearsal strategy to improve clinical performance and reduce stress: A mixed methods study.

Mental rehearsal is a form of mental training that has been used by physicians and nurses to improve performance of clinical skills, and as a vital component of stress management training. To help novice nurses deal with often stressful clinical events that require the processing of information essential to patient management, a mental rehearsal strategy was developed and implemented in a Year 3 nursing simulation program. Inherent to mental rehearsal is imagery, which facilitates cognitive and affective modification, and reduction of extraneous cognitive load. As such, it was expected that the mental rehearsal strategy would improve students' performance and reduce stress in managing deteriorating patients. The study used a mixed methods design. Eighteen Year 3 nursing students participated in the pre- and post-design study, which consisted of the development and implementation of a mental rehearsal strategy. The Rescuing A Patient In Deteriorating Situations (RAPIDS) tool was used to assess performance. Heart rates and systolic blood pressures were used to measure stress. The State-Trait Anxiety Inventory (STAI) was used as a psychological measure of stress/anxiety. Five participants were involved in a focus group discussion that evaluated the usefulness of the mental rehearsal strategy. There was a significant improvement in performance (P<0.05). However, post-test heart rate and systolic blood pressure were not significantly different from pre-test measures. A comparison of STAI results did not show significant differences between pre- and post-test state anxiety and pre- and post-test trait anxiety. Three themes emerged from the focus group interview: managing stress, using a mental framework, and integrating realistic simulations with the mental rehearsal strategy. The mental rehearsal strategy for deteriorating patient management can be valuable based on the findings on performance and based on the participants' feedback. Its role in reducing stress, however, needs further evaluation. Copyright © 2015 Elsevier Ltd. All rights reserved.

Dynamic posture analysis of Spacelab-1 crew members

1986-01-01

Dynamic posture testing was conducted on the science crew of the Spacelab-1 mission on a single axis linear motion platform. Tests took place in pre- and post-flight sessions lasting approximately 20 min each. The pre-flight tests were widely spaced over the several months prior to the mission while the post-flight tests were conducted over the first, second, fourth, and sixth days after landing. Two of the crew members were also tested on the day of landing. Consistent with previous postural testing conducted on flight crews, these crew members were able to complete simple postural tasks to an acceptable level even in the first few hours after landing. Our tests were designed to induce dynamic postural responses using a variety of stimuli and from these responses, evaluate subtle changes in the postural control system which had occurred over the duration of the flight. Periodic sampling post-flight allowed us to observe the time course of readaptation to terrestrial life. Our observations of hip and shoulder position, when subjected to careful analysis, indicated modification of the postural response from pre- to post-flight and that demonstrable adjustments in the dynamic control of their postural systems were taking place in the first few days after flight. For transient stimuli where the platform on which they were asked to stand quickly moved a few centimeters fore or aft then stopped, ballistic or open loop 'programs' would closely characterize the response. During these responses the desired target position was not always achieved and of equal importance not always properly corrected some 15 seconds after the platform ceased to move. The persistent observation was that the subjects had a much stronger dependence on visual stabilization post-flight than pre-flight. This was best illustrated by a slow or only partial recovery to an upward posture after a transient base-of-support movement with eyes open. Postural responses to persistent wideband pseudorandom base-of-support translation were modeled as time invarient linear systems arrived at by Kalman adaptive filter techniques. Derived model parameters such as damping factor and fundamental frequency of the closed loop system showed significant modification between pre- and post-flight. This phenomenon is best characterized by movement of the poles toward increasing stability. While pre-flight data tended to show shoulders and hips moving in phase with each other, post-flight data showed a more disjoint behavior.(ABSTRACT TRUNCATED AT 400 WORDS).

this study examines whether peer-teaching, in the setting of a three-day revision course in anatomy, is effective in preparing medical students for their national anatomy exam. the anatomy course was designed for candidates taking the first part of the German national medical exam. Increase of knowledge during the course was assessed by tests before and after the course (group A). To test equivalence, two control groups participated in the pre-test (group B) or in the course and in the post-test (group C). Participants anonymously rated 14 feedback items on a five-point Likert scale ranging from 1 (full agreement) to 5 (full disagreement). group A students' performance improved significantly during the course with a mean increase of 7.15 points (11.9% improvement; p<0.001). Equivalence testing showed that performance of group A students in the pre-/post-tests was equal to those of group B pre-tests and group C post-tests, respectively. Agreement on the 14 feedback items was highly significant (p<0.001 for all items), with a global median of 1. this study shows that a three-day anatomy revision course is effective and highly appreciated by medical students in their preparation for the national exam. Moreover, peer-teaching is reliable at this stage of the medical curriculum. 2010 Elsevier GmbH. All rights reserved.

Trauma Evaluation and Management course was designed to develop trauma cognitive skills in senior medical students. Its effectiveness has been demonstrated in many regions, except in Latin America, where it has been poorly studied. The objective was to determine the Trauma Evaluation and Management course effectiveness, and whether greater effectiveness is achieved in basic- or clinic-cycle students, as well as student perception. Descriptive, observational, longitudinal and prospective study. Two tests were performed, pre- and post-course; the manual was read by the students prior to both tests. Students were divided into 2 groups: group A (consisting of 71 basic-cycle medical students) and group B (consisting of 44 clinical-cycle medical students). Group A achieved a 2.45 increase (p<0.01) in the post-course evaluation compared with pre-course test. Group B increased the mean score by 2.25 (p>0.05) from pre- to post-course tests. There was a significant difference between groups in both evaluations (pre-course test p<0.01 and post-course test p>0.05), with no difference in improvement (p>0.05). Using a questionnaire, 92.17% of the students totally agreed that the course improved their trauma knowledge, 76.52% that it increased their trauma clinical skills, with 94.78% being totally satisfied with the course, and 86.09% totally agreed that Trauma Evaluation and Management course should be in Medicine curriculum. Trauma Evaluation and Management course improves trauma cognitive skills, and undergraduate medical students in Mexico broadly accept it. Copyright © 2015 Academia Mexicana de Cirugía A.C.

The effects of specific drills on the flip turns of freestyle swimmers based on a kinesiology analysis

PubMed Central

2016-01-01

Abstract This research aimed to define the key factors in freestyle flip turns via a kinesiology analysis to diagnose swimmers. Hence, specially designed drills were created to improve swimmers’ flip-turn skills and assess the effects of training. Nine Chinese national modern pentathlon athletes ranging in age from 20 to 26 years with an average of 10 years of training experience were tested and trained in this study. The Kistler Performance Analysis System for Swimming was used for the pre- and post-test analyses. A kinesiology analysis of the data from the pre-test was used for the diagnosis and specific drills were adopted for 10 weeks, 3 times per week before the post-test. The comparison of the pre- and post-test performances was used to assess the effects of training. After 10 weeks of specific drill training for flip turns, participants’ turning skills significantly improved. Speed in approaching, somersaulting, pushing-off and gliding all increased. The angles of the knees and hips as well as the force applied improved, which contributed to swimmers’ increased speed. Since the skills needed for a flip turn are complex and not easily diagnosed via observation alone, this kinesiology analysis will make diagnosis objective and easy. PMID:28149404

Caregiving across different cultures has been perceived conventionally as a private or family responsibility, predominantly performed by women who accept their caregiving as part of their gender role. This study aimed to design, deliver, and evaluate an elderly training programme for women by assessing their knowledge, attitudes and skills as a lay caregiver. Encouraging the women to find suitable positions for employment in private or governmental institutions was the further objective of the study. The study was a quasi-experimental one-group pre-test post-test design. The study was conducted in a solidarity centre for women and in a nursing home for the elderly. The sample covered 120 women selected from the community by convenience sampling. Data were gathered through pre- and post-test evaluation and observation forms in 2 May-22 December 2005. The training programme consisted of 230 h of didactic sessions, demonstrations and clinical practices. The mean change in the participants' knowledge score (pre-test: 41.44 +/- 0.92; post-test: 71.16 +/- 1.34) demonstrated a statistically significant improvement in their knowledge. According to clinical observations, most of them displayed satisfactory caring and communication skills towards the elderly. Virtually all participants reported increased skill, knowledge and confidence. The developed training programme was effective, resulting in an increased knowledge, the acquisition of good attitudes towards the elderly, and performing satisfactory caring and communication skills. Similar community-based programmes managed by nurses are recommended to support non-professional caregivers. The research is not only an innovative but also a revolutionary model to promote women.

In this article, the test implementation of a school-oriented drug prevention program "Study without Drugs" is discussed. The aims of this study were to determine the results of the process evaluation and to determine whether the proposed school-oriented drug prevention program during a pilot project was effective for the participating pupils. Sixty second-grade pupils at a junior high school in Paramaribo, Suriname participated in the test implementation. They were divided into two classes. For the process evaluation the students completed a structured questionnaire focusing on content and teaching method after every lesson. Lessons were qualified with a score from 0-10. The process was also evaluated by the teachers through structured interviews. Attention was paid to reach, dose delivered, dose received, fidelity, connection, achieved effects/observed behaviors, areas for improvement, and lesson strengths. The effect evaluation was conducted by using the General Liniair Model (repeated measure). The research (-design) was a pre-experimental design with pre-and post-test. No class or sex differences were detected among the pupils with regard to the assessment of content, methodology, and qualification of the lessons. Post-testing showed that participating pupils obtained an increased knowledge of drugs, their drug-resisting skills were enhanced, and behavior determinants (attitude, subjective norm, self-efficacy, and intention) became more negative towards drugs. From the results of the test implementation can be cautiously concluded that the program "Study without Drugs" may yield positive results when applied in schools). Thus, this pilot program can be considered a step towards the development and implementation of an evidence-based school-oriented program for pupils in Suriname.

The present study was designed in quasi-experiment to assess adoption of the essential clauses of particular clinical laboratory quality management requirements based on international organization for standardization (ISO 15189) in hospital laboratories and to evaluate the cost effectiveness of compliance to ISO 15189. The quality management intervention based on ISO 15189 was conceded through three phases; pre - intervention phase, Intervention phase and Post-intervention phase. In pre-intervention phase the compliance to ISO 15189 was 49% for study group vs. 47% for control group with P value 0.48, while the post intervention results displayed 54% vs. 79% for study group and control group respectively in compliance to ISO 15189 and statistically significant difference (P value 0.00) with effect size (Cohen's d) of (0.00) in pre-intervention phase and (0.99) in post - intervention phase. The annual average cost per-test for the study group and control group was 1.80 ± 0.25 vs. 1.97 ± 0.39, respectively with P value 0.39 whereas the post-intervention results showed that the annual average total costs per-test for study group and control group was 1.57 ± 0.23 vs 2.08 ± 0.38, P value 0.019 respectively, with cost-effectiveness ratio of (0.88) in pre -intervention phase and (0.52) in post-intervention phase. The planned adoption of quality management requirements (QMS) in clinical laboratories had great effect to increase the compliance percent with quality management system requirement, raise the average total cost effectiveness, and improve the analytical process capability of the testing procedure.

Eye-tracking of visual attention in web-based assessment using the Force Concept Inventory

2017-07-01

This study used eye-tracking technology to investigate students’ visual attention while taking the Force Concept Inventory (FCI) in a web-based interface. Eighty nine university students were randomly selected into a pre-test group and a post-test group. Students took the 30-question FCI on a computer equipped with an eye-tracker. There were seven weeks of instruction between the pre- and post-test data collection. Students’ performance on the FCI improved significantly from pre-test to post-test. Meanwhile, the eye-tracking results reveal that the time students spent on taking the FCI test was not affected by student performance and did not change from pre-test to post-test. Analysis of students’ attention to answer choices shows that on the pre-test students primarily focused on the naïve choices and ignored the expert choices. On the post-test, although students had shifted their primary attention to the expert choices, they still kept a high level of attention to the naïve choices, indicating significant conceptual mixing and competition during problem solving. Outcomes of this study provide new insights on students’ conceptual development in learning physics.

The conceptual framework of the study, undertaken in select health centres of New Delhi, was based on General System Model. The research approach was evaluative with one group pre-test and post-test design. The study population comprised of Community Health Workers working in selected centres in Najafgarh, Delhi. Purposive sampling technique was used to select a sample of 30 Community Health Workers. A structured knowledge questionnaire was developed to assess the knowledge of subjects. A Structured Teaching Programme was developed to enhance the knowledge of Community Health Workers. Pre-test was given on day 1 and Structured Teaching Programme administered on same day. Post-test was conducted on day 7. Most of the Community Health Workers were in the age group of 21-30 years with academic qualification up to Higher Secondary level. Maximum Community Health Workers had professional qualification as ANM/MPHW (female). Majority of the Community Health Workers had experience up to 5 years. Initially there was deficit in scores of knowledge of Community Health Workers regarding Visual Inspection with Acetic Acid (VIA) test. Mean post-test knowledge scores of Community Health Workers were found to be signifi- cantly higher than their mean pre-test knowledge score. The Community Health Workers after expo- sure to Structured Teaching Programme gained a significant positive relationship between post-test knowledge scores. The study reveals the efficacy of Structured Teaching Programme in enhancing the knowledge of Community Health Workers regarding VIA test and a need for conducting a regular and well planned health teaching programme on VIA test for improving their knowledge on VIA test for the early detection and diagnosis of cervical cancer.

The Objective Structured Clinical Examination (OSCE) is a widely used measurement tool to assess clinical competence in the health sciences. There is little published evidence of its use in Mexican medical schools. To assess clinical competence in medical students with an OSCE, before and after the Medical Internship. Prospective cohort study, pre- post-test research design. The assessed population was medical students at UNAM Faculty of Medicine in Mexico in their Internship year. The instrument was an 18-stations OSCE, three stations per academic area of the Internship curriculum. We assessed the clinical competence of 278 students in a pretest OSCE when starting the Internship year, and tested them 10 months later with an equivalent post-test OSCE. The sample of students was 30.4% of the total Internship population. Test reliability with Cronbach's alpha was 0.62 in the pre-test and 0.64 in the post-test. The global mean score in the pretest OSCE was 55.6 ± 6.6 and in the post-test 63.2 ± 5.7 (p < 0.001), with a Cohen's d of 1.2. The clinical competence of medical students measured with an OSCE is higher after the medical internship year. This difference suggests that the internship can influence the development of clinical competence in medical students.

Anthony, Anika B.; Greene, Howard; Post, Paul E.; Parkhurst, Andrew; Zhan, Xi

2016-11-01

This paper describes an engineering outreach programme designed to increase the interest of under-represented youth in engineering and to disseminate pre-engineering design challenge materials to K-12 educators and volunteers. Given university students' critical role as facilitators of the outreach programme, researchers conducted a two-year design experiment to examine the programme's effectiveness at preparing university students to lead pre-engineering activities. Pre- and post-surveys incorporated items from the Student Engagement sub-scale of the Teacher Sense of Efficacy Scale. Surveys were analysed using paired-samples t-test. Interview and open-ended survey data were analysed using discourse analysis and the constant comparative method. As a result of participation in the programme, university students reported a gain in efficacy to lead pre-engineering activities. The paper discusses programme features that supported efficacy gains and concludes with a set of design principles for developing learning environments that effectively prepare university students to facilitate pre-engineering outreach programmes.

2012-03-01

This article describes an evaluation of a curriculum approach to integrating interprofessional education (IPE) in collaborative mental health practice across the pre- to post-licensure continuum of medical education. A systematic evaluation of IPE activities was conducted, utilizing a combination of evaluation study designs, including: pretest-posttest control group; one-group pre-test-post-test; and one-shot case study. Participant satisfaction, attitudes toward teamwork, and self-reported teamwork abilities were key evaluative outcome measures. IPE in collaborative mental health practice was well received at both the pre- and post-licensure levels. Satisfaction scores were very high, and students, trainees, and practitioners welcomed the opportunity to learn about collaboration in the context of mental health. Medical student satisfaction increased significantly with the introduction of standardized patients (SPs) as an interprofessional learning method. Medical students and faculty reported that experiential learning in practice-based settings is a key component of effective approaches to IPE implementation. At a post-licensure level, practitioners reported significant improvement in attitudes toward interprofessional collaboration in mental health care after participation in IPE. IPE in collaborative mental health is feasible, and mental health settings offer practical and useful learning experiences for students, trainees, and practitioners in interprofessional collaboration.

The aim of this study was to investigate the long-term effect of a teaching intervention designed to reduce undertriage rates in older ED patients. Further, to test the hypothesis that non-adherence to the Emergency Severity Index (ESI) triage algorithm is associated with undertriage. Additionally, to detect patient related risk factors for undertriage. Pre-post-test design. The study sample consisted of all patients aged 65 years or older presenting to the ED of an urban tertiary and primary care center in the study periods. A teaching intervention designed to increase adherence to the triage algorithm. To assess, if the intervention resulted in an increase of factual knowledge, nurses took a test before and immediately after the teaching intervention. Undertriage rates were assessed one year after the intervention and compared to the pre-test period. In the pre-test group 519 patients were included, and 394 in the post-test-group. Factual knowledge among triage nurses was high already before the teaching intervention. Prevalence of undertriaged patients before (22.5%) and one year after the intervention (24.2%) was not significantly different (χ2 = 0.248, df = 1, p = 0.619). Sex, age, mode of arrival, and type of complaint were not identified as independent risk factors for undertriage. However, undertriage rates increased with advancing age. Adherence to the ESI algorithm is associated with correct triage decisions. Undertriage of older ED patients remained unchanged over time. Reasons for undertriage seem to be more complex than anticipated. Therefore, additional contributing factors should be addressed.

Double blind pre-test post-test control group design. To compare the isokinetic quadriceps torque, standardized stair-climbing task (SSCT) and pain during SSCT between subjects diagnosed with knee osteoarthritis pre and post kinesio tape (KT) application with and without tension. Strength of the quadriceps and torque producing capability is frequently found to be compromised in knee osteoarthritis. The efficacy of KT in improving isokinetic quadriceps torque in knee osteoarthritis is unknown, forming the basis for this study. Forty subjects were randomly allocated to either the experimental (therapeutic KT with tension) or control group (sham KT without tension) with the allocation being concealed. Pre and post test measurements of isokinetic quadriceps torque, SSCT and pain during SSCT were carried out by a blinded assessor. A large effect size with significant improvements in the peak quadriceps torque (concentric and eccentric at angular velocities of 90° per second and 120° per second), SSCT and pain were obtained in the experimental group when compared to the control group. Application of therapeutic KT is effective in improving isokinetic quadriceps torque, SSCT and reducing pain in knee osteoarthritis.

Heyden, Robin; Sternthal, Elliot; Merialdi, Mario

2010-01-01

Background Virtual worlds are rapidly becoming part of the educational technology landscape. Second Life (SL) is one of the best known of these environments. Although the potential of SL has been noted for health professions education, a search of the world’s literature and of the World Wide Web revealed a limited number of formal applications of SL for this purpose and minimal evaluation of educational outcomes. Similarly, the use of virtual worlds for continuing health professional development appears to be largely unreported. Methods We designed and delivered a pilot postgraduate medical education program in the virtual world, Second Life. Our objectives were to: (1) explore the potential of a virtual world for delivering continuing medical education (CME) designed for physicians; (2) determine possible instructional designs using SL for CME; (3) understand the limitations of SL for CME; (4) understand the barriers, solutions, and costs associated with using SL, including required training; and (5) measure participant learning outcomes and feedback. We trained and enrolled 14 primary care physicians in an hour-long, highly interactive event in SL on the topic of type 2 diabetes. Participants completed surveys to measure change in confidence and performance on test cases to assess learning. The post survey also assessed participants’ attitudes toward the virtual learning environment. Results Of the 14 participant physicians, 12 rated the course experience, 10 completed the pre and post confidence surveys, and 10 completed both the pre and post case studies. On a seven-point Likert scale (1, strongly disagree to 7, strongly agree), participants’ mean reported confidence increased from pre to post SL event with respect to: selecting insulin for patients with type 2 diabetes (pre = 4.9 to post = 6.5, P= .002); initiating insulin (pre = 5.0 to post = 6.2, P= .02); and adjusting insulin dosing (pre = 5.2 to post = 6.2, P= .02). On test cases, the percent of participants providing a correct insulin initiation plan increased from 60% (6 of 10) pre to 90% (9 of 10) post (P= .2), and the percent of participants providing correct initiation of mealtime insulin increased from 40% (4 of 10) pre to 80% (8 of 10) post (P= .09). All participants (12 of 12) agreed that this experience in SL was an effective method of medical education, that the virtual world approach to CME was superior to other methods of online CME, that they would enroll in another such event in SL, and that they would recommend that their colleagues participate in an SL CME course. Only 17% (2 of 12) disagreed with the statement that this potential Second Life method of CME is superior to face-to-face CME. Conclusions The results of this pilot suggest that virtual worlds offer the potential of a new medical education pedagogy to enhance learning outcomes beyond that provided by more traditional online or face-to-face postgraduate professional development activities. Obvious potential exists for application of these methods at the medical school and residency levels as well. PMID:20097652

On test cases, the percent of participants providing a correct insulin initiation plan increased from 60% (6 of 10) pre to 90% (9 of 10) post (P= .2), and the percent of participants providing correct initiation of mealtime insulin increased from 40% (4 of 10) pre to 80% (8 of 10) post (P= .09). All participants (12 of 12) agreed that this experience in SL was an effective method of medical education, that the virtual world approach to CME was superior to other methods of online CME, that they would enroll in another such event in SL, and that they would recommend that their colleagues participate in an SL CME course. Only 17% (2 of 12) disagreed with the statement that this potential Second Life method of CME is superior to face-to-face CME. The results of this pilot suggest that virtual worlds offer the potential of a new medical education pedagogy to enhance learning outcomes beyond that provided by more traditional online or face-to-face postgraduate professional development activities. Obvious potential exists for application of these methods at the medical school and residency levels as well.

Background Undergraduate nursing education standards include acquisition of knowledge of ethics principles and the prevalence of health-care ethical dilemmas mandates that nursing students study ethics. However, little research has been published to support best practices for teaching/learning ethics principles. Purpose This study sought to determine if participation in an ethics consultation simulation increased nursing students' knowledge of nursing ethics principles compared to students who were taught ethics principles in the traditional didactic format. Methods This quasi-experimental study utilized a pre-test/post-test design with randomized assignment of students at three universities into both control and experimental groups. Results Nursing students' knowledge of nursing ethics principles significantly improved from pre-test to post-test ( p = .002); however, there was no significant difference between the experimental and control groups knowledge scores ( p = .13). Conclusion Further research into use of simulation to teach ethics principles is indicated.

The preparedness level of final year medical students for an adequate medical approach to emergency cases: computer-based medical education in emergency medicine

PubMed Central

2014-01-01

Background We aimed to observe the preparedness level of final year medical students in approaching emergencies by computer-based simulation training and evaluate the efficacy of the program. Methods A computer-based prototype simulation program (Lsim), designed by researchers from the medical education and computer science departments, was used to present virtual cases for medical learning. Fifty-four final year medical students from Ondokuz Mayis University School of Medicine attended an education program on June 20, 2012 and were trained with Lsim. Volunteer attendants completed a pre-test and post-test exam at the beginning and end of the course, respectively, on the same day. Results Twenty-nine of the 54 students who attended the course accepted to take the pre-test and post-test exams; 58.6% (n = 17) were female. In 10 emergency medical cases, an average of 3.9 correct medical approaches were performed in the pre-test and an average of 9.6 correct medical approaches were performed in the post-test (t = 17.18, P = 0.006). Conclusions This study’s results showed that the readiness level of students for an adequate medical approach to emergency cases was very low. Computer-based training could help in the adequate approach of students to various emergency cases. PMID:24386919

Attention-training with children from socioeconomically disadvantaged backgrounds in Cape Town.

2017-09-01

Attention is a core process underlying competence in higher-order cognitive abilities. Previous research suggests that healthy children from low socioeconomic status (SES) backgrounds perform poorly, relative to those from higher SES backgrounds, on tasks assessing attentional abilities. In this pilot study, we investigated the effects of an attention-training intervention on task performance in low-SES children. We conducted a quasi-controlled trial with stratified randomisation, using a pre-test/ post-test design. Participants were low-SES children aged 7-13 years. Each was assigned to either an intervention group, a play control group, or a test-only control group (n = 5 per group). We implemented a ten-week manualised cognitive rehabilitation program, Pay Attention!, administering standardised tests of attention, working memory, and inhibition before and after the intervention. Between- and within-group analyses and Reliable Change Index statistics evaluated differences in scores from pre- to post-intervention. Analyses detected no notable between-group differences at either pre- or post-intervention testing. However, on tests of selective attention, attentional control, and inhibition, there were significant within-group and positive individual reliable changes exclusive to the intervention-group participants. Given the variability in our findings, more research needs be conducted with a larger sample to determine, with greater rigour, the efficacy of the intervention within samples of healthy children from low-SES backgrounds.

This study investigated the impact of a collaborative clinical education model on students' perception of the psycho-social learning environment. A pre-test and post-test quasi experimental design. A tertiary referral centre. Second and third year undergraduate nursing students were asked to rate their perceptions of the psycho-social learning environment at the completion of the clinical practicum. TOOL: The tool used to measure psycho-social perceptions of the clinical learning environment was the Clinical Learning Environment Inventory previously validated in Australian health care contexts. A collaborative arrangement with the university and ward staff where eight students are placed on a ward and a ward staff member is paid by the university to be 'off-line' from a clinical workload to supervise the students. This is in contrast to the standard facilitation model where students are placed with registered nurses in different localities under the supervision of a 'roving' registered nurse paid by the university. No significant differences were found in pre-test mean scores when comparing wards. Significant differences in post-test scores for the intervention group were identified in the sub scales of Student Involvement, Satisfaction, Personalisation and Task Orientation. The adoption of a collaborative clinical education model where students are integrated into the ward team and the team is responsible for student learning can positively enhance capacity for student learning during their clinical practicum.

Isoflurane improves outcome vs. fentanyl anesthesia, in experimental traumatic brain injury (TBI). We assessed the temporal profile of isoflurane neuroprotection and tested whether isoflurane confers benefit at the time of TBI. Adult, male rats were randomized to isoflurane (1%) or fentanyl (10 mcg/kg iv bolus then 50 mcg/kg/h) for 30 min pre-TBI. Anesthesia was discontinued, rats recovered to tail pinch, and TBI was delivered by controlled cortical impact. Immediately post-TBI, rats were randomized to 1 h of isoflurane, fentanyl, or no additional anesthesia, creating 6 anesthetic groups (isoflurane:isoflurane, isoflurane:fentanyl, isoflurane:none, fentanyl:isoflurane, fentanyl:fentanyl, fentanyl:none). Beam balance, beam walking, and Morris water maze (MWM) performances were assessed over post-trauma d1-20. Contusion volume and hippocampal survival were assessed on d21. Rats receiving isoflurane pre- and post-TBI exhibited better beam walking and MWM performances than rats treated with fentanyl pre- and any treatment post-TBI. All rats pretreated with isoflurane had better CA3 neuronal survival than rats receiving fentanyl pre- and post-TBI. In rats pretreated with fentanyl, post-traumatic isoflurane failed to affect function but improved CA3 neuronal survival vs. rats given fentanyl pre- and post-TBI. Post-traumatic isoflurane did not alter histopathological outcomes in rats pretreated with isoflurane. Rats receiving fentanyl pre- and post-TBI had the worst CA1 neuronal survival of all groups. Our data support isoflurane neuroprotection, even when used at the lowest feasible level before TBI (i.e., when discontinued with recovery to tail pinch immediately before injury). Investigators using isoflurane must consider its beneficial effects in the design and interpretation of experimental TBI research.

To report findings on knowledge and skill acquisition following a 3-day training session in the use of short message service (SMS) texting with non- and low-literacy traditional midwives. A pre- and post-test study design was used to assess knowledge and skill acquisition with 99 traditional midwives on the use of SMS texting for real-time, remote data collection in rural Liberia, West Africa. Paired sample t-tests were conducted to establish if overall mean scores varied significantly from pre-test to immediate post-test. Analysis of variance was used to compare means across groups. The nonparametric McNemar's test was used to determine significant differences between the pre-test and post-test values of each individual step involved in SMS texting. Pearson's chi-square test of independence was used to examine the association between ownership of cell phones within a family and achievement of the seven tasks. The mean increase in cell phone knowledge scores was 3.67, with a 95% confidence interval ranging from 3.39 to 3.95. Participants with a cell phone in the family did significantly better on three of the seven tasks in the pre-test: "turns cell on without help" (χ(2) (1) = 9.15, p= .003); "identifies cell phone coverage" (χ(2) (1) = 5.37, p= .024); and "identifies cell phone is charged" (χ(2) (1) = 4.40, p= .042). A 3-day cell phone training session with low- and nonliterate traditional midwives in rural Liberia improved their ability to use mobile technology for SMS texting. Mobile technology can improve data collection accessibility and be used for numerous health care and public health issues. Cell phone accessibility holds great promise for collecting health data in low-resource areas of the world. © 2012 Sigma Theta Tau International.

Objective: To analyze the difference of dosimetric parameters between pre-plan and post-plan of 125 I radioactive seed implantation assisted by 3D printing individual non-coplanar template (3D printing template) for locally recurrent rectal cancer (LRRC). Methods: From February 2016 to April 2016, a total of 10 patients with locally recurrent rectal cancer received 125 I seeds implantation under CT guidance assisted by 3D printing template in Department of Radiation Oncology, Peking University Third Hospital.Each patient underwent CT simulation, three-dimentional treatment planning pre-implantation, 3D printing template design, radioactive seed implantation assisted by 3D printing template and dosimetric verification post implantation. The median activity of seed was 0.63 mCi (0.58 to 0.7 mCi) (2.15- 2.59×10 7 Bq), and the median number of seeds was 80 (19 to 192). D 90 , D 100 , V 100 , V 150 , CI, EI, HI, D 5cc , D 2cc of bladder and bowel of pre-plan and post-plan were calculated, respectively.Paired t test was used to evaluate the difference of dosimetric parameters between pre-plan and post-plan. Results: The median D 90 of pre-plan and post-plan were 13 761.0 and 12 798.8 cGy, respectively.The median D 100 of pre-plan and post-plan were 5 293.6 and 5 397.9 cGy, respectively.The median V 100 of pre-plan and post-plan were 90.0% and 90.0%, respectively.The median V 150 of pre-plan and post-plan were 63.8% and 62.4%, respectively.The median CI of pre-plan and post-plan were 0.73 and 0.67.The median EI of pre-plan and post-plan were 0.22 and 0.30, respectively. The median HI of pre-plan and post-plan were 0.29 and 0.31.The median bladder D 2cc of pre-plan and post-plan were 3 088.8 and 4 240.4 cGy, respectively.The median bowel D 2cc of pre-plan and post-plan were 7 051.6 and 7 903.9 cGy, respectively. Conclusions: 3D printing template might be helpful for locally recurrent rectal cancer patients who received 125 I radioactive seed implantation assisted by 3D printing individual template.Seed implantation might have more chances to achieve prescription dose and dose limitation of organs at risk of pre-plan, which is important for precise implantation and quality control.

2013-07-01

Background and purpose: The purpose of this study was to investigate the comparative effects of a prediction/discussion-based learning cycle (HPD-LC), conceptual change text (CCT) and traditional instruction on 10th grade students' understanding of genetics concepts. Sample: Participants were 112 10th basic grade male students in three classes of the same school located in an urban area. The three classes taught by the same biology teacher were randomly assigned as a prediction/discussion-based learning cycle class (n = 39), conceptual change text class (n = 37) and traditional class (n = 36). Design and method: A quasi-experimental research design of pre-test-post-test non-equivalent control group was adopted. Participants completed the Genetics Concept Test as pre-test-post-test, to examine the effects of instructional strategies on their genetics understanding. Pre-test scores and Test of Logical Thinking scores were used as covariates. Results: The analysis of covariance showed a statistically significant difference between the experimental and control groups in the favor of experimental groups after treatment. However, no statistically significant difference between the experimental groups (HPD-LC versus CCT instruction) was found. Conclusions: Overall, the findings of this study support the use of the prediction/discussion-based learning cycle and conceptual change text in both research and teaching. The findings may be useful for improving classroom practices in teaching science concepts and for the development of suitable materials promoting students' understanding of science.

Emergency medical services (EMS) play a vital role in expediting hospital arrival in stroke patients. The objective of our study was to assess the level of awareness regarding pre-hospital identification and management of acute stroke among EMS Staff in Dubai and to evaluate the impact of an educational lecture on their knowledge. Ours was a cross-sectional study with a pre-test and post-test design. The intervention was an educational lecture, based on the updated guidelines in pre-hospital care of acute stroke. Participants were assessed before and after the intervention on various aspects of stroke care. Paired t test were used to compare the impact of the intervention. A total of 274 EMS workers participated in our study. The baseline knowledge of participants regarding stroke types was inadequate with only 68% correctly identifying these. 79% were able to name the cardinal stroke symptoms. Knowledge of stroke mimics was poor with only 6.6% identifying stroke mimics correctly. With respect to management, most participants were unable to correctly identify the points to illicit in the history of an acute stroke patient (25.2%) and also the steps in pre-hospital management (40%). All these aspects showed remarkable improvement post intervention. The baseline awareness of most aspects of acute stroke identification and management was poor in our EMS participants. Our educational lecture proved effective in improving this knowledge when tested immediately post intervention. However, there is a need to re-assess this at periodic intervals to identify the need for refresher courses on pre-hospital stroke management.

Comparing behavioral discrimination and learning abilities in monolinguals, bilinguals and multilinguals.

The aim of the experiment was to determine whether language learning experience contributes to the development of enhanced speech perception abilities. Monolinguals, bilinguals and multilinguals were compared in their ability to discriminate a non-native contrast behaviorally using an AX task. The experiment was based on a "pre-test-training-post-test" design and performance was tested before and after receiving training on the voiceless aspirated dental/retroflex stop contrast. At post-test, participants were also tested on their ability to transfer training to a similar contrast (i.e., voiceless unaspirated dental/retroflex stop contrast). While no group differences were found at pre-test, analyses of the trained-on contrast at post-test revealed that multilinguals were more accurate than monolinguals and that both the multilingual and bilingual groups were more accurate than a control group that received no training. The results of the experiment not only suggest that multilinguals and bilinguals have enhanced speech perception abilities compared to monolinguals, but they also indicate that bi-/multilingualism helps develop superior learning abilities. This provides support for the idea that learning more than one language has positive effects on the cognitive development of an individual (e.g., Bialystok et al., 2004).

2014-01-01

Students need emotional intelligence (EI) for their better academic excellence. There are three important psychological dimensions of EI: Emotional sensitivity (ES), emotional maturity (EM) and emotional competency (EC), which motivate students to recognize truthfully, interpret honestly and handle tactfully the dynamics of their behavioral pattern. The study was designed to assess ES in the students undergoing yoga therapy program in the form of yoga instructor's course (YIC) module. One hundred and eighty four YIC students with 25.77 ± 4.85 years of mean age participated in this study of 21 days duration (a single group pre-post design). The ES data was collected before (pre) and after (post) YIC module using Emotional Quotient test developed by Dr Dalip Singh and Dr N K Chadha. Means, standard deviations, Kolmogorov-Smirnov test, and Wilcoxon signed rank test were used for analyzing the data with the help of SPSS 16. The data analysis showed 3.63% significant increase (P < 0.01) in ES. The present study suggests that YIC module can result in improvement of ES among university students, thus paving the way for their academic success. Additional well-designed studies are needed before a strong recommendation can be made.

2015-05-01

The results from a cross-national study comparing calculus performance of students at East China Normal University (ECNU) in Shanghai and students at the University of Michigan before and after their first university calculus course are presented. Overall, ECNU significantly outperformed Michigan on both the pre- and post-tests, but the Michigan students showed a larger gain and normalized gain, and hence narrowed the gap. ECNU's superior performance was especially striking on the subset of problems requiring only a pre-calculus background. On those, Michigan's post-test scores were below ECNU's pre-test scores and, indeed, ECNU's higher performance on both the overall pre-test and overall post-test is attributable to its success on these problems.

To assess the ability of a screen-based simulation-training program to improve emergency medicine and pediatric resident performance in critical pediatric resuscitation knowledge, confidence, and skills. A pre-post, interventional design was used. Three measures of performance were created and assessed before and after intervention: a written pre-course knowledge examination, a self-efficacy confidence score, and a skills-based high-fidelity simulation code scenario. For the high-fidelity skills assessment, independent physician raters recorded and reviewed subject performance. The intervention consisted of eight screen-based pediatric resuscitation scenarios that subjects had 4 weeks to complete. Upon completion of the scenarios, all three measures were repeated. For the confidence assessment, summary pre- and post-test summary confidence scores were compared using a t-test, and for the skills assessment, pre-scores were compared with post-test measures for each individual using McNemar's chi-square test for paired samples. Twenty-six of 35 (71.3%) enrolled subjects completed the institutional review board-approved study. Increases were observed in written test scores, confidence, and some critical interventions in high-fidelity simulation. The mean improvement in cumulative confidence scores for all residents was 10.1 (SD +/-4.9; range 0-19; p < 0.001), with no resident feeling less confident after the intervention. Although overall performance in simulated codes did not change significantly, with average scores of 6.65 (+/-1.76) to 7.04 (+/-1.37) out of 9 possible points (p = 0.58), improvement was seen in the administering of appropriate amounts of IV fluids (59-89%, p = 0.03). In this study, improvements in resident knowledge, confidence, and performance of certain skills in simulated pediatric cardiac arrest scenarios suggest that screen-based simulations may be an effective way to enhance resuscitation skills of pediatric providers. These results should be confirmed using a randomized design with an appropriate control group. (c) 2009 by the Society for Academic Emergency Medicine.

Preparing nursing students to perform competently in complex emergency situations, such as during rapid patient deterioration, is challenging. Students' active engagement in such scenarios cannot be ensured, due to the unexpected nature of such infrequent events. Many students may consequently not experience and integrate the management of patient deterioration into their knowledge and practical competency by the end of their studies, making them unprepared to manage such situations as practicing nurses. This study investigated the effectiveness of virtual simulation in improving performance during rapid patient deterioration. To investigate the effectiveness of virtual simulation in improving student nurses' knowledge and performance during rapid patient deterioration. A pre- and post-test design was used. Nursing students at a university in Malta were invited to participate in a virtual simulation program named FIRST 2 ACTWeb™, using their own computer devices. A total of 166 (response rate=50%) second and third year diploma and degree nursing students participated in the study. The simulation included three scenarios (Cardiac-Shock-Respiratory) portraying deteriorating patients. Performance feedback was provided at the end of each scenario. Students completed pre- and post-scenario knowledge tests and performance during each scenario was recorded automatically on a database. Findings showed a significant improvement in the students' post-scenario knowledge (z=-6.506, p<0.001). Highest mean performance scores were obtained in the last scenario (M=19.7, median: 20.0, s.d. 3.41) indicating a learning effect. Knowledge was not a predictor of students' performance in the scenarios. This study supports virtual simulation as an effective learning tool for pre-registration nursing students in different programs. Simulation improves both knowledge about and performance during patient deterioration. Virtual simulation of rare events should be a key component of undergraduate nurse education, to prepare students to manage complex situations as practicing nurses. Copyright © 2018 Elsevier Ltd.

To investigate the effect of two weeks of intensive exercise on leg function in chronic stroke patients and to evaluate the feasibility of an intensive exercise programme in a group setting. Pilot study with one-group pre-test post-test design with two pre-tests and one-year follow-up. Inpatient rehabilitation hospital. Twelve hemiparetic patients completed the intervention. Ten patients participated at one-year follow-up. Six hours of daily intensive exercise for two weeks with focus on weight-shifting towards the affected side and increased use of the affected extremity during functional activities. An insole with nubs in the shoe of the non-paretic limb was used to reinforce weight-shift toward the affected side. Timed Up and Go, Four Square Step Test, gait velocity, gait symmetry and muscle strength in knee and ankle muscles. Maximal gait velocity (P = 0.002) and performance time (seconds) on Timed Up and Go (mean, SD; 12.2, 3.8 vs. 9.4, 3.2) and Four Square Step Test improved from pre- to post-test (P = 0.005). Improvements remained significant at follow-up. Preferred gait velocity and gait symmetry remained unchanged. Knee extensor (P<50.009) and flexor (P<50.001) strength increased bilaterally from pre- to post-test but only knee flexor strength remained significant at follow-up. Ankle dorsi flexor (P = 0.02) and plantar flexor (P<0.001) strength increased on paretic side only (not tested at follow-up). Intensive exercise for lower extremity is feasible in a group setting and was effective in improving ambulatory function, maximal gait velocity and muscle strength in chronic stroke patients. Most improvements persisted at the one-year follow-up.

Combining cognitive skills teaching related to the techniques leads to better understanding in a skill training course; but still there a substantial disagreement in curriculum on such combinations. This study aims to help guide the designers in making the outline of instructional plan for a Clinical Skills Module (CSM) for the undergraduates. Objectives were to assess performance of students on a clinical skill after training by two different models of (hands-on only or with cognitive skills) instructions and explore their perception on the employment of educational strategies through Focus Group Discussions (FGD) through a Sequential mixed method study design: (1) Quantitative (Pre- and post-assessments and comparing their results (2) Qualitative (Exploration of perspectives through constructivist approach using qualitative phenomenological design) The study was conducted during the month of September, 2015 at Rabigh Medical College, King Abdul Aziz University, Jeddah. Students entering fourth year were randomized to two groups to participate in pre-post OSCE using global rating scale and their scores were compared. The examiners were kept blinded to the randomization of students undergoing two separate training methods. The test group (group A) was trained for both procedural as well as cognitive skills whereas the control group (Group-B) was trained only with hands-on practice. Later their perception about the addition of cognitive skills to improve of procedural skills was explored through focus group discussions. The recorded audio tapes of FGDs were transcribed and analysed thematically. Triangulation of themes and trends was achieved by relating the content analysis to the relevant frequency of quotes. Auditing of the data verification was done by all the authors separately.. A total of 42 students completed both pre- and post-tests. As a result, student performance in OSCE significantly increased from pre- to post-test (p<0.001) in both the groups; on the other hand no statistically significant difference was found in the pre- and posttest scores between groups A and B (p=0.108). Five themes (1) advantages, (2) disadvantages of combining theory with practice, (3) time balance in teaching a skill, (4) training on skills, (5) skillsassessment, were found prevalent on thematic analysis of the FGDs. Students' ability to grasp the procedural skills was not significantly different when they acquire the cognitive skills in addition to the practical sessions. Students were more convinced to adopt combination of the two in the learning of procedural skills.

Sustainability Instruction in High Doses: Results From Incorporation of Multiple InTeGrate Modules Into an Environmental Science Class

NASA Astrophysics Data System (ADS)

Rademacher, L. K.

2017-12-01

The Interdisciplinary Teaching about Earth for a Sustainable Future (InTeGrate) community has developed extensive courses and modules designed for broad adoption into geoscience classrooms in diverse environments. I participated in a three-semester research project designed to test the efficacy of incorporating "high doses" (minimum 3 modules or 18 class periods) of InTeGrate materials into a course, in my case, an introductory environmental science class. InTeGrate materials were developed by groups of instructors from a range of institutions across the US. These materials include an emphasis on systems thinking, interdisciplinary approaches, and sustainability, and those themes are woven throughout the modules. The three semesters included a control in which no InTeGrate materials were used, a pilot in which InTeGrate materials were tested, and a treatment semesters in which tested materials were modified as needed and fully implemented into the course. Data were collected each semester on student attitudes using the InTeGrate Attitudinal Instrument (pre and post), a subset of Geoscience Literacy Exam questions (pre and post), and a series of assessments and essay exam questions (post only). Although results suggest that learning gains were mixed, changes in attitudes pre- and post-instruction were substantial. Changes in attitudes regarding the importance of sustainable employers, the frequency of self-reported individual sustainable actions, and motivation level for creating a sustainable society were observed in the control and treatment semesters, with the treatment semester showing the greatest gains. Importantly, one of the biggest differences between the control and treatment semesters is the reported impact that the course had on influencing students' sustainable behaviors. The treatment semester course impacted students' sustainable behaviors far more than the control semester.

The primary objective of this investigation was to determine the effectiveness of different active learning exercises in a newly-designed flipped-classroom self-care course in applying newly acquired knowledge of self-care and improving the confidence of first-year pharmacy students to recommend self-care treatments and counsel patients. The early development of these skills is essential for the subsequent Community Introductory Pharmacy Practice Experience (CIPPE). An unpaired anonymous survey was administered to students, pre- and post-course, to ascertain their opinions on the effectiveness of various teaching strategies and active learning exercises on learning and on their confidence in treatment-planning and patient counseling for self-care patients. Comparison between pre- and post-course Likert scores was conducted using a one-way ANOVA followed by a post-hoc Tukey's test with significance at p = 0.05. All other tests of significance were conducted using a student's t-test with significance at p = 0.05. Students' self-confidence in developing treatment plans and in counseling for non-prescription drugs and dietary supplements significantly improved from the beginning to the end of this self-care course. The response rate was high in both the pre- (N = 208, 88.1%) and post- (N = 198, 83.9%) course surveys. The positive change in confidence was not reflected in increased performance on the final exam represented by a lower average score than the midterm exam. Active learning sessions and the flipped classroom approach in this first-year pharmacy self-care course contributed to increased self-confidence in making recommendations and counseling patients on proper use of nonprescription medications and dietary supplements.

Objective To obtain the perception of nurses on the use of Facebook as a learning tool. Materials & methods We conducted a pilot observational study in which data were collected through a detailed course evaluation and feedback survey questionnaire. Twelve stroke care nurses were enrolled in a stroke course specifically designed to provide participants with information and knowledge about stroke unit nursing care. Firstly, a closed Facebook group consisting of the participants and facilitators was created. An activity in accordance with the course content was posted in the group daily. Before the start of the course, a pre-course test was conducted. The four-week course culminated in a graded written examination. Its results were compared with the pre-course test. A detailed feedback questionnaire was given to the participants at the end of the course, which was specifically designed to elicit perceptions of nurses about the use of Facebook as a learning tool. Results Of the 12 enrolled nurses, 10 completed the certification and the post-course feedback evaluation. Facebook was used by all participants as a platform to view and study the course contents. The timing of the course activities was rated "very good" by three and 'good' by six of 10 participants. However, one of the major issues faced by five participants was problematic internet access. The overall rating of the course was "very good" by five participants, "good" by three, and "satisfactory" by two of 10 participants. The post-course test showed that nine of 10 candidates passed with scores >70% compared to only two candidates getting scores >50% in the pre-course test. Conclusion Facebook use enabled participants to study the material when their schedule permitted them. The online teaching and facilitation were ideal for our full-time stroke unit nurses as reflected by their improved post-course test results.

The mesenchymal stem cells in multiple sclerosis (MSCIMS) trial protocol and baseline cohort characteristics: an open-label pre-test: post-test study with blinded outcome assessments

PubMed Central

2011-01-01

Background No treatments are currently available that slow, stop, or reverse disease progression in established multiple sclerosis (MS). The Mesenchymal Stem Cells in Multiple Sclerosis (MSCIMS) trial tests the safety and feasibility of treatment with a candidate cell-based therapy, and will inform the wider challenge of designing early phase clinical trials to evaluate putative neuroprotective therapies in progressive MS. Illustrated by the MSCIMS trial protocol, we describe a novel methodology based on detailed assessment of the anterior visual pathway as a model of wider disease processes - the "sentinel lesion approach". Methods/design MSCIMS is a phase IIA study of autologous mesenchymal stem cells (MSCs) in secondary progressive MS. A pre-test : post-test design is used with healthy controls providing normative data for inter-session variability. Complementary eligibility criteria and outcomes are used to select participants with disease affecting the anterior visual pathway. Results Ten participants with MS and eight healthy controls were recruited between October 2008 and March 2009. Mesenchymal stem cells were successfully isolated, expanded and characterised in vitro for all participants in the treatment arm. Conclusions In addition to determining the safety and feasibility of the intervention and informing design of future studies to address efficacy, MSCIMS adopts a novel strategy for testing neuroprotective agents in MS - the sentinel lesion approach - serving as proof of principle for its future wider applicability.

Background Tobacco media campaigns are effective, but less is known regarding the impact on college students. Purpose The purpose was to test the effects of an on-campus Tips television campaign on frequency and believability of ads recalled and to assess demographic and personal factors associated with believability. Methods A quasi-experimental pre-post design was used to assess the 8-week campaign with three Tips ads. Two randomly-selected cohorts of college students (N = 1,593) from a large public university completed online surveys pre- and post-campaign. Group comparisons using chi-square tests, two-sample t-tests, and logistic regression, controlling for residence or cohort; predictors of believability using proportional odds modeling. Results Ads were recalled by significantly more students (68%) post-campaign. Believability for one or more ads was lower for males, undergraduates, those belonging to fraternity/sorority, and current polytobacco users (p<.05). Believability was greater for those who recalled seeing the ads more often (p<.05). Discussion Sub-groups of college students, including males and undergraduates, reported less ad believability, which should be considered when designing communication strategies. Translation to Health Education Practice Considering the potential impact and cost-effective nature of on-campus TV media campaigns, these ads need to be integrated into current campus tobacco control strategies.

Two randomly-selected cohorts of college students ( N = 1,593) from a large public university completed online surveys pre- and post-campaign. Group comparisons using chi-square tests, two-sample t-tests, and logistic regression, controlling for residence or cohort; predictors of believability using proportional odds modeling. Ads were recalled by significantly more students (68%) post-campaign. Believability for one or more ads was lower for males, undergraduates, those belonging to fraternity/sorority, and current polytobacco users ( p <.05). Believability was greater for those who recalled seeing the ads more often ( p <.05). Sub-groups of college students, including males and undergraduates, reported less ad believability, which should be considered when designing communication strategies. Considering the potential impact and cost-effective nature of on-campus TV media campaigns, these ads need to be integrated into current campus tobacco control strategies.

This study will extend on a pilot study and will evaluate the impact of a novel approach to PE, Better Movers and Thinkers (BMT), on students' cognition, physical activity habits, and gross motor coordination (GMC). The study will involve six mainstream state schools with students aged 9-11 years. Three schools will be allocated as the intervention condition and three as the control condition. The design of the study is a 16-week intervention with pre-, post- and 6 month follow-up measurements taken using the 'Cognitive Assessment System (CAS)' GMC tests, and the 'Physical Activity Habits Questionnaire for Children (PAQ-C).' Qualitative data will be gathered using student focus groups and class teacher interviews in each of the six schools. ANCOVA will be used to evaluate any effect of intervention comparing pre-test scores with post-test scores and then pre-test scores with 6 month follow-up scores. Qualitative data will be analysed through an iterative process using grounded theory. This protocol provides the details of the rationale and design of the study and details of the intervention, outcome measures, and the recruitment process. The study will address gaps within current research by evaluating if a change of approach in the delivery of PE within schools has an effect on children's cognition, PA habits, and GMC within a Scottish setting.

The Illinois Department of Public Health mandated that all clinicians who provide care to obstetric patients participate in the Illinois Obstetric Hemorrhage Project. The aim of the current report is to describe change in knowledge among providers engaged in the project, as assessed by pre- and post-tests. The project, implemented 2008 to 2010, included four components: a written 25-item multiple-choice examination (pre-test), a didactic lecture, skill stations (for teaching blood loss estimation), and a simulation drill and debriefing. Participants completed a post-test 6 months later. Pre- and post-test examination scores were compared. Data from 95 hospitals are included in this analysis (9456 paired test results). The proportion of participants who scored ≥88% correct answers increased from 10.9% on the pre-test to 49.1% on the post-test (p < 0.0001). Registered nurses made greater improvements in test scores than anesthesia and obstetric providers (p < 0.0001). The Illinois Obstetric Hemorrhage Project was successful in improving knowledge of obstetric hemorrhage in a large number of providers with different expertise and experience levels. Further long-term study is essential to determine whether the skills acquired during the Project contribute to improved obstetric hemorrhage outcomes for the women of Illinois.

NASA Astrophysics Data System (ADS)

Marulcu, Ismail; Barnett, Michael

2016-01-01

Background: Elementary Science Education is struggling with multiple challenges. National and State test results confirm the need for deeper understanding in elementary science education. Moreover, national policy statements and researchers call for increased exposure to engineering and technology in elementary science education. The basic motivation of this study is to suggest a solution to both improving elementary science education and increasing exposure to engineering and technology in it. Purpose/Hypothesis: This mixed-method study examined the impact of an engineering design-based curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines. We hypothesize that the LEGO-engineering design unit is as successful as the inquiry-based unit in terms of students' science content learning of simple machines. Design/Method: We used a mixed-methods approach to investigate our research questions; we compared the control and the experimental groups' scores from the tests and interviews by using Analysis of Covariance (ANCOVA) and compared each group's pre- and post-scores by using paired t-tests. Results: Our findings from the paired t-tests show that both the experimental and comparison groups significantly improved their scores from the pre-test to post-test on the multiple-choice, open-ended, and interview items. Moreover, ANCOVA results show that students in the experimental group, who learned simple machines with the design-based unit, performed significantly better on the interview questions. Conclusions: Our analyses revealed that the design-based Design a people mover: Simple machines unit was, if not better, as successful as the inquiry-based FOSS Levers and pulleys unit in terms of students' science content learning.

2016-06-01

This study examines the effect of communication strategy instruction on EFL students' oral communicative ability and their strategic competence. In a 14-week English as a Foreign Language (EFL) course (English Use II) based on Communicative Language Teaching approach, 80 learners were divided into two groups. The strategy training group ([Formula: see text]) received CS training based on a training program designed for the purpose of the present research, whereas the control group ([Formula: see text]) received only the normal communicative course using Click On 3, with no explicit focus on CSs. The communication strategies targeted in the training program included circumlocution (paraphrase), appeal for help, asking for repetition, clarification request, confirmation request, self-repair, and guessing. Pre- and post-test procedures were used to find out the effect of strategy training on language proficiency and CS use. The effect of the training was assessed by three types of data collection: the participants' pre- and post-IELTS speaking test scores, transcription data from the speaking IELTS test, and 'Click On' Exit Test scores. The findings revealed that participants in the strategy training group significantly outperformed the control group in their IELTS speaking test scores. The results of the post-test transcription data also confirmed that the participants in the strategy training group used more CSs, which could be attributed to the CS training program. The findings of the present research have implications for language teachers, and syllabus designers.

Do pre- and post-copulatory sexually selected traits covary in large herbivores?

PubMed Central

2014-01-01

Background In most species, males compete to gain both matings (via pre-copulatory competition) and fertilizations (via post-copulatory competition) to maximize their reproductive success. However, the quantity of resources devoted to sexual traits is finite, and so males are predicted to balance their investment between pre- and post-copulatory expenditure depending on the expected pay-offs that should vary according to mating tactics. In Artiodactyla species, males can invest in weapons such as horns or antlers to increase their mating gains or in testes mass/sperm dimensions to increase their fertilization efficiency. Moreover, it has been suggested that in these species, males with territory defence mating tactic might preferentially increase their investment in post-copulatory traits to increase their fertilization efficiency whereas males with female defence mating tactic might increase their investment in pre-copulatory sexually selected traits to prevent other males from copulating with females. In this study, we thus test the prediction that male’s weapon length (pre-copulatory trait) covaries negatively with relative testes size and/or sperm dimensions (post-copulatory traits) across Artiodactyla using a phylogenetically controlled framework. Results Surprisingly no association between weapon length and testes mass is found but a negative association between weapon length and sperm length is evidenced. In addition, neither pre- nor post-copulatory traits were found to be affected by male mating tactics. Conclusions We propose several hypotheses that could explain why male ungulates may not balance their reproductive investment between pre- and post-copulatory traits. PMID:24716470

To examine the impact of a muscle resistance program (MRP) on muscular and functional performance and on interleukin 6 (IL-6) and soluble tumor necrosis factor receptor-1 (sTNFr1) plasma levels in prefrail community-dwelling women. Randomized controlled trial crossover design with a postintervention and short-term follow-up. University hospital. Prefrail community-dwelling women (N=32; ≥65y). The MRP was designed based on the exercise at 75% of each participant's maximum load (10wk, 3 times/wk). Plasma concentrations of IL-6 and sTNFr1 (high-sensitivity enzyme-linked immunosorbent assay kits), muscle strength of the knee extensors (isokinetic), and functional performance (Timed Up & Go [TUG] test and 10-meter walk test [10MWT]). There were significant differences in functional and muscular performance between the pre-MRP, post-MRP, and 10-week follow-up period. After the MRP, both functional (TUG, pre-MRP=11.1s vs post-MRP=10.4s, P=.00; 10MWT, pre-MRP=4.9s vs post-MRP, 4.4s, P=.00) and muscular performances (pre-MRP=77.8% and post-MRP=83.1%, P=.02) improved. After cessation of the MRP (follow-up period), sTNFr1 plasma levels increased by 21.4% at 10-week follow-up (post-MRP, 406.4pg/mL; 10-week follow-up, 517.0pg/mL; P=.03). There were significant differences in sTNFr1 (P=.01). The MRP was effective in improving functional and muscular performances, although alterations in plasma levels of IL-6 and sTNFr1 could not be identified after the MRP. Cessation of the MRP after 10 weeks resulted in increased plasma levels of sTNFr1. Copyright © 2013 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

Analysis of Phenix end-of-life natural convection test with the MARS-LMR code

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jeong, H. Y.; Ha, K. S.; Lee, K. L.

The end-of-life test of Phenix reactor performed by the CEA provided an opportunity to have reliable and valuable test data for the validation and verification of a SFR system analysis code. KAERI joined this international program for the analysis of Phenix end-of-life natural circulation test coordinated by the IAEA from 2008. The main objectives of this study were to evaluate the capability of existing SFR system analysis code MARS-LMR and to identify any limitation of the code. The analysis was performed in three stages: pre-test analysis, blind posttest analysis, and final post-test analysis. In the pre-test analysis, the design conditionsmore » provided by the CEA were used to obtain a prediction of the test. The blind post-test analysis was based on the test conditions measured during the tests but the test results were not provided from the CEA. The final post-test analysis was performed to predict the test results as accurate as possible by improving the previous modeling of the test. Based on the pre-test analysis and blind test analysis, the modeling for heat structures in the hot pool and cold pool, steel structures in the core, heat loss from roof and vessel, and the flow path at core outlet were reinforced in the final analysis. The results of the final post-test analysis could be characterized into three different phases. In the early phase, the MARS-LMR simulated the heat-up process correctly due to the enhanced heat structure modeling. In the mid phase before the opening of SG casing, the code reproduced the decrease of core outlet temperature successfully. Finally, in the later phase the increase of heat removal by the opening of the SG opening was well predicted with the MARS-LMR code. (authors)« less

Setting: National Leprosy and Tuberculosis (TB) Control Programme, Liberia. Objectives: To assess TB case finding, including human immunodeficiency virus (HIV) associated interventions and treatment outcomes, before (January 2013–March 2014), during (April 2014–June 2015) and after (July–December 2015) the Ebola virus disease outbreak. Design: A cross-sectional study and retrospective cohort analysis of outcomes. Results: The mean quarterly numbers of individuals with presumptive TB and the proportion diagnosed as smear-positive were: pre-Ebola (n = 7032, 12%), Ebola (n = 6147, 10%) and post-Ebola (n = 6795, 8%). For all forms of TB, stratified by category and age group, there was a non-significant decrease in the number of cases from the pre-Ebola to the Ebola and post-Ebola periods. There were significant decreases in numbers of cases with smear-positive pulmonary TB (PTB) from the pre-Ebola period (n = 855), to the Ebola (n = 640, P < 0.001) and post-Ebola (n = 568, P < 0.001) periods. The proportions of patients tested for HIV, found to be HIV-positive and started on antiretroviral therapy decreased as follows: pre-Ebola (respectively 72%, 15% and 34%), Ebola (69%, 14% and 30%) and post-Ebola (68%, 12% and 26%). Treatment success rates among TB patients were: 80% pre-Ebola, 69% Ebola (P < 0.001) and 73% post-Ebola (P < 0.001). Loss to follow-up was the main contributing adverse outcome. Conclusion: The principal negative effects of Ebola were the significant decreases in diagnoses of smear-positive PTB, the declines in HIV testing and antiretroviral therapy uptake and poor treatment success. Ways to prevent these adverse effects from recurring in the event of another Ebola outbreak need to be found. PMID:28744441

Use of audio visual tools to aid in medical education is ever on a rise. Our study intends to find the efficacy of a video prepared on "fatty liver," a topic that is often a challenge for pre-clinical teachers, in enhancing cognitive processing and ultimately learning. We prepared a video presentation of 11:36 min, incorporating various concepts of the topic, while keeping in view Mayer's and Ellaway guidelines for multimedia presentation. A pre-post test study on subject knowledge was conducted for 100 students with the video shown as intervention. A retrospective pre study was conducted as a survey which inquired about students understanding of the key concepts of the topic and a feedback on our video was taken. Students performed significantly better in the post test (mean score 8.52 vs. 5.45 in pre-test), positively responded in the retrospective pre-test and gave a positive feedback for our video presentation. Well-designed multimedia tools can aid in cognitive processing and enhance working memory capacity as shown in our study. In times when "smart" device penetration is high, information and communication tools in medical education, which can act as essential aid and not as replacement for traditional curriculums, can be beneficial to the students. © 2015 by The International Union of Biochemistry and Molecular Biology, 44:241-245, 2016. © 2015 The International Union of Biochemistry and Molecular Biology.

Infectious diseases are common among schoolchildren as a result of their poor hand hygiene, especially in those who have developmental disabilities. A quasi-experimental study using a pre- to post-test design with a control group was used to test the feasibility and sustainability of simplified 5-step handwashing techniques to measure the hand hygiene outcome for students with mild intellectual disability. Sickness-related school absenteeism was compared. The intervention group experienced a significant increase in the rating of their handwashing quality in both hands from pre- to post-test: left dorsum (+1.05, P < .001); right dorsum (+1.00, P < .001); left palm (+0.98, P < .001); and right palm (+1.09, P < .001). The pre- to post-test difference in the intervention group (+1.03, P < .001) was significantly greater than the difference in the control group (+0.34, P = .001). There were no differences between the post-test and the sustainability assessment in the intervention group. The intervention school experienced a significantly lower absenteeism rate (0.0167) than the control group in the same year (0.028, P = .04).Students in this study showed better performance in simplified handwashing techniques and experienced lower absenteeism than those using usual practice in special education school settings. The simplified 5-step hand hygiene technique has been proven effective in reducing the spread of infectious diseases.

Malaria is endemic in Nigeria, with significant records of mortality and morbidity. Adequate community involvement is central to a successful implementation of malaria control programs. This study assessed the effects of a training programme on knowledge of malaria prevention and control among community role model care givers. A descriptive cross sectional study of a pre-and post-test design method was conducted among 400 eligible community members in Osun State. Training was given in the form of organized lectures, health education and practical demonstration sessions. Scores of pre-test and post-test conducted after four months interval were compared. Multistage sampling method was adopted in selecting study participants, while data was analyzed using the SPSS software version 17.0. Mean age was 43.8 (±1.4) years. Average knowledge score of cause, transmission, risk factors and consequences, awareness of common symptoms and preventive practices improved during post-training test when compared with pr-training test. The overall descriptive mean knowledge score in pre-test and post-test were 2.1 and 3.5 respectively out of an average maximum score of 5.0, giving an increment of 66.7%. Role model care givers with formal education were twice and three times more likely to know about disease 'transmission' (OR 1.9, 95%CI 0.11-0.19, p=0.002) and 'consequences' (OR 2.9, 95%CI 0.25-0.65, p=0.040) respectively compared to those without formal education. Training on malaria improved the knowledge of malaria prevention and control among role model community care givers towards a successful implementation of malaria control programmes.

In this study, we evaluate the influence of post surface pre-treatments on the bond strength of four different cements to glass fiber posts. Eighty extracted human maxillary central incisors and canines were endodontically treated and standardized post spaces were prepared. Four post pre-treatments were tested: (i) no pre-treatment (NS, control), (ii) sandblasting (SA), (iii) silanization (SI) and (iv) sandblasting followed by silanization (SS). Per pre-treatment, four dual-cure resin cements were used for luting posts: DMG LUXACORE Smartmix Dual, Multilink Automix, RelyX Unicem and Panavia F2.0. All the specimens were subjected to micro push-out test. Two-way analysis of variance and Tukey post hoc tests were performed (α=0.05) to analyze the data. Bond strength was significantly affected by the type of resin cement, and bond strengths of RelyX Unicem and Panavia F2.0 to the fiber posts were significantly higher than the other cement groups. Sandblasting significantly increased the bond strength of DMG group to the fiber posts. PMID:24177170

Objective: To compare whether specific maternal and child health indicators changed in the two counties during the pre-Ebola (2013), Ebola (2014) and post-Ebola (2015) disease outbreak periods from July to September each year. Design: This was a cross-sectional study. Results: For pregnant women, the numbers of antenatal visits, intermittent preventive malaria treatments, human immunodeficiency virus (HIV) tests and facility-based births with skilled attendants all fell during the Ebola period, with decreases being significantly more marked in Margibi County. Apart from HIV testing, which remained low in both counties, these indicators increased in the post-Ebola period, with increases significantly more marked in Bong than in Margibi. The number of childhood immunisations decreased significantly in Bong in the Ebola period compared with the pre-Ebola period, but increased to above pre-Ebola levels in the post-Ebola period. There were markedly larger decreases in childhood immunisations in Margibi County during the Ebola period, which remained significantly lower in the post-Ebola period compared with Bong County. Conclusion: In a PBF-supported county, selected maternal and childhood health indicators showed less deterioration during Ebola and better recovery post-Ebola than in a non-PBF-supported county.

2014-01-01

Nurses must have optimum knowledge of heart failure self-care principles to adequately prepare patients for self-care at home. However, study findings demonstrate that nurses have knowledge deficits in self-care concepts for heart failure. A quasi-experimental, repeated measures design was used to assess nurses' knowledge of heart failure self-care before, immediately after, and 3-months following an educational intervention, which also included the Teach Back method. Follow-up reinforcement was provided after the educational intervention. One hundred fifty nurses participated in the study. Significant differences were found between pre-test (65.1%) and post-test (80.6%) scores (p < 0.001). Teach Back proficiency was achieved by 98.3%. Only 61 participants completed the 3-month assessment of knowledge. In this group, mean knowledge scores increased significantly across all three measurements (p < 0.001): 66.5% (pre-test); 82.1% (post-test); 89.5% (follow up post-test). Participation in a comprehensive educational program resulted in increased nurses' knowledge of heart failure self-care principles and the knowledge was sustained and increased over time.

Evaluating the attractiveness of a new light rail extension: Testing simple change and displacement change hypotheses

PubMed Central

Brown, Barbara B.; Tribby, Calvin P.; Tharp, Doug; Flick, Kristi; Miller, Harvey J.; Smith, Ken R.; Jensen, Wyatt

2015-01-01

Many communities in the United States have been adding new light rail to bus-predominant public transit systems. However, there is disagreement as to whether opening light rail lines attracts new ridership or merely draws ridership from existing transit users. We study a new light rail line in Salt Lake City, Utah, USA, which is part of a complete street redevelopment. We utilize a pre-test post-test control group quasi-experimental design to test two different measures of ridership change. The first measure is calculated from stops along the light rail route; the second assumes that nearby bus stops might be displaced by the rail and calculates ridership change with those stops included as baseline. Both the simple measure (transit use changes on the complete street light rail corridor) and the “displacement” measure (transit use changes in the one-quarter mile catchment areas around new light rail stops) showed significant (p < .01) and substantial (677%) increases in transit passengers compared to pre-light rail bus users. In particular, the displacement analysis discredits a common challenge that when a new light rail line opens, most passengers are simply former bus riders whose routes were canceled in favor of light rail. The study suggests that light rail services can attract additional ridership to public transit systems. In addition, although pre-post control-group designs require time and effort, this project underscores the benefits of such quasi-experimental designs in terms of the strength of the inferences that can be drawn about the impacts of new transit infrastructure and services.

The Development of Student’s Activity Sheets (SAS) Based on Multiple Intelligences and Problem-Solving Skills Using Simple Science Tools

NASA Astrophysics Data System (ADS)

Wardani, D. S.; Kirana, T.; Ibrahim, M.

2018-01-01

The aim of this research is to produce SAS based on MI and problem-solving skills using simple science tools that are suitable to be used by elementary school students. The feasibility of SAS is evaluated based on its validity, practicality, and effectiveness. The completion Lesson Plan (LP) implementation and student’s activities are the indicators of SAS practicality. The effectiveness of SAS is measured by indicators of increased learning outcomes and problem-solving skills. The development of SAS follows the 4-D (define, design, develop, and disseminate) phase. However, this study was done until the third stage (develop). The written SAS was then validated through expert evaluation done by two experts of science, before its is tested to the target students. The try-out of SAS used one group with pre-test and post-test design. The result of this research shows that SAS is valid with “good” category. In addition, SAS is considered practical as seen from the increase of student activity at each meeting and LP implementation. Moreover, it was considered effective due to the significant difference between pre-test and post-test result of the learning outcomes and problem-solving skill test. Therefore, SAS is feasible to be used in learning.

To assess the potential for informatics training using an approach designed to foster interaction at this interface, the University of Washington and the Universidad Peruana Cayetano Heredia developed and assessed a one-week course that included a new Bioinformatics (BIO) track along with an established Medical/Public Health Informatics track (MI) for participants in Peru. Methods We assessed the background of the participants, and measured the knowledge gained by track-specific (MI or BIO) 30-minute pre- and post-tests. Participants' attitudes were evaluated both by daily evaluations and by an end-course evaluation. Results Forty-three participants enrolled in the course – 20 in the MI track and 23 in the BIO track. Of 20 questions, the mean % score for the MI track increased from 49.7 pre-test (standard deviation or SD = 17.0) to 59.7 (SD = 15.2) for the post-test (P = 0.002, n = 18). The BIO track mean score increased from 33.6 pre-test to 51.2 post-test (P < 0.001, n = 21). Most comments (76%) about any aspect of the course were positive. The main perceived strength of the course was the quality of the speakers, and the main perceived weakness was the short duration of the course. Overall, the course acceptability was very good to excellent with a rating of 4.1 (scale 1–5), and the usefulness of the course was rated as very good. Most participants (62.9%) expressed a positive opinion about having had the BIO and MI tracks come together for some of the lectures. Conclusion Pre- and post-test results and the positive evaluations by the participants indicate that this first joint Bioinformatics and Medical/Public Health Informatics (MI and BIO) course was a success.

Errors in clinical laboratories or errors in laboratory medicine?

PubMed

Plebani, Mario

2006-01-01

Laboratory testing is a highly complex process and, although laboratory services are relatively safe, they are not as safe as they could or should be. Clinical laboratories have long focused their attention on quality control methods and quality assessment programs dealing with analytical aspects of testing. However, a growing body of evidence accumulated in recent decades demonstrates that quality in clinical laboratories cannot be assured by merely focusing on purely analytical aspects. The more recent surveys on errors in laboratory medicine conclude that in the delivery of laboratory testing, mistakes occur more frequently before (pre-analytical) and after (post-analytical) the test has been performed. Most errors are due to pre-analytical factors (46-68.2% of total errors), while a high error rate (18.5-47% of total errors) has also been found in the post-analytical phase. Errors due to analytical problems have been significantly reduced over time, but there is evidence that, particularly for immunoassays, interference may have a serious impact on patients. A description of the most frequent and risky pre-, intra- and post-analytical errors and advice on practical steps for measuring and reducing the risk of errors is therefore given in the present paper. Many mistakes in the Total Testing Process are called "laboratory errors", although these may be due to poor communication, action taken by others involved in the testing process (e.g., physicians, nurses and phlebotomists), or poorly designed processes, all of which are beyond the laboratory's control. Likewise, there is evidence that laboratory information is only partially utilized. A recent document from the International Organization for Standardization (ISO) recommends a new, broader definition of the term "laboratory error" and a classification of errors according to different criteria. In a modern approach to total quality, centered on patients' needs and satisfaction, the risk of errors and mistakes in pre- and post-examination steps must be minimized to guarantee the total quality of laboratory services.

Introduction: Mass media influence the health behaviors of adolescents. Evidence shows that traditional strategies such as censorship or limitation are no longer efficient; therefore, teaching media literacy is the best way to protect adolescents from harmful effects. The aim of this pilot study was to evaluate the effects of a media literacy training program on knowledge and behavioral intention of a sample of female students according to the stages of change in dealing with media messages. Methods: The study was conducted based on a pre-test and post-test control group design. Some 198 female students including 101 in the intervention group and 97 in the control group participated in this study. The educational program was run using interactive teaching-learning techniques. Data collection was performed using a validated and reliable self-administered questionnaire in three phases including a pre-test, post-test, 1 and post-test, 2. The research data was analyzed through SPSS statistical software, version 14 using both descriptive and inferential statistics. Results: The results of the study showed a significant increase (p=0.001) in the intervention group’s knowledge mean scores after the training program. On the other hand, the difference was not significant in the control group (p=0.200). A considerable percentage of the participants, in the intervention and control groups, were in pre contemplation and contemplation stages in the pre-test (64 and 61, respectively). After the intervention, however, a significant improvement (p=0.001) was observed in the intervention group’s stages of change compared to that in the control group. The distribution of the control group students regarding the stages of change was similar to that in the pre-test. Conclusion: The study findings revealed that the planned education programs are efficient to improve the adolescents’ knowledge and behavioral intention in dealing with mass media messages.

To design an orientation for surgical interns to meet the new Accreditation Council for Graduate Medical Education Common Program Requirements regarding supervision, to test patient-management competencies, and to assess confidence on skills and tasks pre-orientation and post-orientation. Twenty-seven incoming surgical interns participated in a two-day orientation to clinical duties. Activities included a pre-test, lectures, simulation, oral examination, intern shadowing, and a post-test. Incoming interns were surveyed before and after orientation and two months later for confidence in patient-management and surgical intern skills. Paired t-tests were used to determine if confidence improved pre-orientation and post-orientation, and two months following orientation. The study took place at an academic training hospital. All (n = 27) postgraduate year-1 (PGY-1) surgical residents at our institution, which included the categorical and nondesignated preliminary general surgery, urology, orthopedic surgery, otolaryngology, and neurosurgery programs. All interns passed the oral and written examinations, and were deemed able to be indirectly supervised, with direct supervision immediately available. They reported increased confidence in all areas of patient management addressed during orientation, and this confidence was retained after two months. In surgical and floor-related tasks and skills, interns reported no increase in confidence directly following orientation. However, after two months, they reported a significant increase in confidence, particularly in those tasks that are performed often. New requirements for resident supervision require creative ways of verifying resident competency in basic skills. This type of orientation is an effective way to address the new requirements of supervision and teach interns the tasks and skills that are necessary for internship.

Through its ability to address and remove fear and misunderstanding and the resulting sexual reluctance and related problems, pre-marital sexual education and counselling can contribute to sexual satisfaction. This quasi-experimental research conducted in a pre-test-post-test control group design aimed to examine the effectiveness of nursing interventions on a premarital counselling program and its impacts on the sexual satisfaction of couples (36 couples in the experimental group and 35 couples in the control group). Although no difference was detected between the experimental and control groups in terms of the level of knowledge on pre-test point averages, the difference between them in terms of post-test knowledge gain averages was statistically significant. Approval rates for sexual myths in the pre-test were 27.87% in the experimental group and 37.03% in the control group; in the post-test they were 23.51% and 36.66% respectively. In the experimental group, 80.6% of the women and 63.9% of the men, and in the control group, 77.1% of the women and 71.4% of the men were established as having a problem-free sexual life. It was also discovered that levels of sexual satisfaction were shown to be higher among women and men in the experimental group who had attended premarital sexual counselling education than the women and men in the control group. A recommendation to encourage engaged couples to attend premarital sexual counselling is made based on the findings. It is thought that an intervention plan prepared within the framework of the Information, Motivation, Behavioural Skills theoretical model will help nurses guide recently-married couples to greater sexual satisfaction.

Objective: To analyze the functional change of horizontal semicircular canals after cochlear implantation. Method: Eighteen patients were enrolled in this study.Their vestibular function was evaluated by using the caloric test and video head impulse test before and one week,one month after CI surgery,respectively.The unilateral weakness(UW),slow phase velocity(SPV)in caloric test and gain in video head impulse test(vHIT-G)were observed.Caloric test was abnormal when UW>25% or SPV mean<6°/s,while vHIT was abnormal when vHIT-G<0.8. Result: The SPV of the implanted ear were[(10.36±8.01)°/s;(14.77±14.24)°/s]pre-operatively,[(6.45±7.52)°/s;(5.14±4.67)°/s]1 week post-operatively and[(6.05±3.86)°/s;(6.27±4.17)°/s]1 month post-operatively.Statistically significant difference( P <0.05)was found between pre-and post-operative period.The vHIT-G of the implanted ear were(0.73±0.33)pre-operatively,(0.65±0.32)1 week post-operatively and(0.71±0.36)1 month post-operatively.There was no statistically significant difference of vHIT-G between preand post-operative period( P (pre-operative/1 week post-operative)=0.084, P (pre-operative/1 month post-operative)=0.679).Four patients presented with vertigo and one of them manifested slight unsteadiness post-operatively.All symptoms resolved within 7 days.These symptoms had no correlate with age,gender,implantedear and results of vestibular test. Conclusion: Cochlear implantation can affect the horizontal semicircular canal function,and the video head impulse test and caloric test should be used in a complementary fashion.

Poor communication during patient handover is recognised internationally as a root cause of a significant proportion of preventable deaths. Data used in handover is not always easily recorded using ambulance based tablets, particularly in time-critical cases. Paramedics have therefore developed pragmatic workarounds (writing on gloves or scrap paper) to record these data. However, such practices can conflict with policy, data recorded can be variable, easily lost and negatively impact on handover quality. This study aimed to measure the feasibility and acceptability of a novel, low tech intervention, designed to support clinical information recording and delivery during pre-alert and handover within the pre-hospital and ED setting. A simple pre and post-test design was used with a historical control. Eligible participants included all ambulance clinicians based at one large city Ambulance Station (n = 69) and all nursing and physician staff (n = 99) based in a city Emergency Department. Twenty five (36%) ambulance clinicians responded to the follow-up survey. Most felt both the pre-alert and handover components of the card were either 'useful-very useful' (n = 23 (92%); and n = 18 (72%) respectively. Nineteen (76%) used the card to record clinical information and almost all (n = 23 (92%) felt it 'useful' to 'very useful' in supporting pre-alert. Similarly, 65% (n = 16) stated they 'often' or 'always' used the card to support handover. For pre-alert information there were improvements in the provision of 8/11 (72.7%) clinical variables. ​ Results from the post-test survey measuring ED staff (n = 37) perceptions of handover demonstrated small (p < 0.05) improvements in handover in 3/5 domains measured. This novel low-tech intervention was highly acceptable to ambulance clinician participants, improving their data recording and information exchange processes. However, further well conducted studies are required to test the impact of this intervention on information exchange during pre-alert and handover.

Four sampling designs for quantifying the effect of low-head sea lamprey (Petromyzon marinus) barriers on fish communities were evaluated, and the contribution of process-oriented research to the overall confidence of results obtained was discussed. The designs include: (1) sample barrier streams post-construction; (2) sample barrier and reference streams post-construction; (3) sample barrier streams pre- and post-construction; and (4) sample barrier and reference streams pre- and post-construction. In the statistical literature, the principal basis for comparison of sampling designs is generally the precision achieved by each design. In addition to precision, designs should be compared based on the interpretability of results and on the scale to which the results apply. Using data collected in a broad survey of streams with and without sea lamprey barriers, some of the tradeoffs that occur among precision, scale, and interpretability are illustrated. Although circumstances such as funding and availability of pre-construction data may limit which design can be implemented, a pre/post-construction design including barrier and reference streams provides the most meaningful information for use in barrier management decisions. Where it is not feasible to obtain pre-construction data, a design including reference streams is important to maintain the interpretability of results. Regardless of the design used, process-oriented research provides a framework for interpreting results obtained in broad surveys. As such, information from both extensive surveys and intensive process-oriented research provides the best basis for fishery management actions, and gives researchers and managers the most confidence in the conclusions reached regarding the effects of sea lamprey barriers.

Signal Processing Methods for Liquid Rocket Engine Combustion Stability Assessments

NASA Technical Reports Server (NTRS)

Kenny, R. Jeremy; Lee, Erik; Hulka, James R.; Casiano, Matthew

2011-01-01

The J2X Gas Generator engine design specifications include dynamic, spontaneous, and broadband combustion stability requirements. These requirements are verified empirically based high frequency chamber pressure measurements and analyses. Dynamic stability is determined with the dynamic pressure response due to an artificial perturbation of the combustion chamber pressure (bomb testing), and spontaneous and broadband stability are determined from the dynamic pressure responses during steady operation starting at specified power levels. J2X Workhorse Gas Generator testing included bomb tests with multiple hardware configurations and operating conditions, including a configuration used explicitly for engine verification test series. This work covers signal processing techniques developed at Marshall Space Flight Center (MSFC) to help assess engine design stability requirements. Dynamic stability assessments were performed following both the CPIA 655 guidelines and a MSFC in-house developed statistical-based approach. The statistical approach was developed to better verify when the dynamic pressure amplitudes corresponding to a particular frequency returned back to pre-bomb characteristics. This was accomplished by first determining the statistical characteristics of the pre-bomb dynamic levels. The pre-bomb statistical characterization provided 95% coverage bounds; these bounds were used as a quantitative measure to determine when the post-bomb signal returned to pre-bomb conditions. The time for post-bomb levels to acceptably return to pre-bomb levels was compared to the dominant frequency-dependent time recommended by CPIA 655. Results for multiple test configurations, including stable and unstable configurations, were reviewed. Spontaneous stability was assessed using two processes: 1) characterization of the ratio of the peak response amplitudes to the excited chamber acoustic mode amplitudes and 2) characterization of the variability of the peak response's frequency over the test duration. This characterization process assists in evaluating the discreteness of a signal as well as the stability of the chamber response. Broadband stability was assessed using a running root-mean-square evaluation. These techniques were also employed, in a comparative analysis, on available Fastrac data, and these results are presented here.

This study examined the effects of reminiscence on depressive symptoms and mood status of elderly people residing in long-term care facilities. A longitudinal quasi-experimental design was conducted, using two equivalent groups for pre-post test and purposive sampling. Each subject was administered pre- and post- tests at a 4 month interval, but subjects in the experimental group underwent weekly individual reminiscence therapy. Geriatric Depression Scale short form (GDS-SF) and Apparent Emotion Rating Scale (AER) were used as study instruments. Forty-eight subjects completed the study, with 25 in the experimental group and 23 in the control group. The experimental findings indicated that the experimental group demonstrated fewer depressive symptoms (p < 0.05) and better mood status (p = 0.05) on the post-test comparing to the control group. These warranted that reminiscence therapy is a recommended therapy for older people who reside in care facilities. It can provide a basis for planning geriatric care in community to promote the well being and quality of life of older people.

In Nigeria, as in other developing countries, access to training in research ethics is limited, due to weak social, economic, and health infrastructure. The project described in this article was designed to develop the capacity of academic staff of the College of Medicine, University of Ibadan, Nigeria to conduct ethically acceptable research involving human participants. Three in-depth interviews and one focus group discussion were conducted to assess the training needs of participants. A research ethics training workshop was then conducted with College of Medicine faculty. A 23-item questionnaire that assessed knowledge of research ethics, application of principles of ethics, operations of the Institutional Review Board (IRB) and ethics reasoning was developed to be a pre-post test evaluation of the training workshop. Ninety-seven workshop participants completed the questionnaire before and after the workshop; 59 of them completed a second post-test questionnaire one month after the workshop. The trainees came from a multi-disciplinary background including medicine, nursing, pharmacy, social science and laboratory science. The mean scores for knowledge of the principles of research ethics rose from 0.67 out of 3 points at pre-test to 2.25 at post-test (p < 0.05). Also, 42% correctly mentioned one international guideline or regulation at pretest, with most of those knowing of the Declaration of Helsinki. Trainees' knowledge of the operations of an IRB increased from 6.05 at pre-test to 6.29 at post test out of 7 points. Overall, participants retained much of the knowledge acquired from the workshop one month after its completion. The training improved participants' knowledge of principles of research ethics, international guidelines and regulations and operations of IRBs. It thus provided an opportunity for research ethics capacity development among academic staff in a developing country institution.

To assess the impact of a nurse-led, short, structured training program for intensive care unit (ICU) nurses in a resource-limited setting. A training program using a structured approach to patient assessment and management for ICU nurses was designed and delivered by local nurse tutors in partnership with overseas nurse trainers. The impact of the course was assessed using the following: pre-course and post-course self-assessment, a pre-course and post-course Multiple Choice Questionnaire (MCQ), a post-course Objective Structured Clinical Assessment station, 2 post-course Short Oral Exam (SOE) stations, and post-course feedback questionnaires. In total, 117 ICU nurses were trained. Post-MCQ scores were significantly higher when compared with pre-MCQ (P < .0001). More than 95% passed the post-course Objective Structured Clinical Assessment (patient assessment) and SOE 1 (arterial blood gas analysis), whereas 76.9% passed SOE 2 (3-lead electrocardiogram analysis). The course was highly rated by participants, with 98% believing that this was a useful experience. Nursing Intensive Care Skills Training was highly rated by participants and was effective in improving the knowledge of the participants. This sustainable short course model may be adaptable to other resource-limited settings. Copyright © 2014 Elsevier Inc. All rights reserved.

2017-01-01

Intra-abdominal hypertension (IAH) occurs frequently in critically ill patients, and adds to their morbidity and mortality. There is no published evidence on the effects of nursing activities on the intra-abdominal pressure (IAP) for patients at risk of IAH. The purpose of this study was to identify the effects of hygiene care on the IAP of patients at risk for IAH. Hygiene care was provided to 34 at-risk patients. IAP was measured prior to initiating the hygiene care, immediately after and 10 minutes later. This was a quasi-experimental, pre-test/ post-test design. The 10 minute post-hygiene care measurement of the IAP was significantly lower than the pre or immediate post-measurement of the IAP. There were no significant changes in the mean arterial pressure (MAP) or the abdominal perfusion pressure (APP). It is safe and possibly therapeutic to provide hygiene care to patients at risk for IAH.

Cross state-dependency of learning between arachidonylcyclopropylamide (ACPA) and muscimol in the mouse dorsal hippocampus.

PubMed

Jafari-Sabet, Majid; Karimi, Amir-Mohammad

2017-12-01

The aim of the present study was to examine cross state-dependent learning between ACPA (a selective cannabinoid CB1 receptor agonist) and muscimol (a selective GABAA receptor agonist) in the step-down inhibitory avoidance learning task. The dorsal hippocampal CA1 regions of adult male NMRI mice were bilaterally cannulated, and all drugs were microinjected into the intended sites of injection. Post-training and/or pre-test administration of ACPA (1 and 2ng/mouse) dose-dependently induced amnesia. Pre-test microinjection of the same doses of ACPA reversed the post-training ACPA-induced amnesia. This event has been named ACPA state-dependent learning (SDL). Post-training and/or pre-test microinjection of muscimol (0.05 and 0.1μg/mouse) dose-dependently induced amnesia. Pre-test administration of the same doses of muscimol reversed the post-training muscimol-induced amnesia, suggesting muscimol SDL. The amnesia induced by post-training administration of ACPA was reversed by pre-test administration of muscimol (0.05 and 0.1μg/mouse). Furthermore, the pre-test microinjection of muscimol (0.025 and 0.05μg/mouse) with an ineffective dose of ACPA (0.5ng/mouse) significantly restored memory retrieval and induced ACPA SDL. In another series of experiments, the amnesia induced by post-training administration of muscimol was reversed by pre-test administration of ACPA (1 and 2ng/mouse). Moreover, pre-test microinjection of ACPA (0.5 and 1ng/mouse) with an ineffective dose of muscimol (0.025μg/mouse) significantly restored memory retrieval and induced muscimol SDL. It is important to note that pre-test intra-CA1 injection of a selective GABAA receptor antagonist, bicuculline (0.125 and 0.25μg/mouse), 5min before the administration of muscimol (0.1μg/mouse) or ACPA (2ng/mouse) dose-dependently inhibited muscimol- and ACPA-induced SDL, respectively. Pre-test intra-CA1 administration of bicuculline (0.0625, 0.125 and 0.25μg/mouse) by itself did not affect memory retention. In conclusion, the data strongly revealed a cross SDL among ACPA and muscimol in the dorsal hippocampal CA1 regions. Copyright © 2017 Elsevier Inc. All rights reserved.

2015-01-01

This paper presents the pre- and post-test results of the outcomes of a workshop designed to increase learning disability and mental health nurses' knowledge and skill to undertake interventions for service users at risk of, or with a diagnosis of, type 2 diabetes. Health literacy is also discussed as a way of explaining why such nurses may lack expertise in physical health care. Findings from the workshop show that learning disability and mental health nurses have the motivation to increase their health literacy (skills and knowledge) in diabetes care. The potential of such workshops, and how organisations looking forward to the future can build health literacy, is discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

Objective. To investigate whether a profession-specific educational intervention affected the development of moral reasoning competencies in community pharmacists, as measured by the Defining Issues Test (DIT2). Methods. This research used a repeated measures pre-post educational intervention design as a quasi-randomized, controlled, crossover study to evaluate changes in the moral reasoning scores of 27 volunteer community pharmacists in Ireland. Results. Changes in pharmacists' moral reasoning competencies development, as reported by P-Scores and N2-Scores, were found to be significant. In addition, interaction effects were observed between developmental scores on the DIT2 and whether participants were determined to be consolidated in their reasoning pre- and post-engagement with the educational intervention. Conclusion. Short profession-specific educational interventions have the potential to positively affect the development of moral reasoning competencies of community pharmacists.

The implementation of 5 of the 6 WHO MPOWER program in Iran is satisfactory; the only notable shortcoming is the lack of tobacco taxation increases. This study was designed to increase key policy makers' awareness of tobacco taxation effectiveness through a sensitization program in Iran. This analytical and semi-experimental study in 2014 included 110 tobacco control key policy makers, who were trained and received educational materials on the importance of tobacco taxation. A valid and reliable questionnaire was completed before and three months after intervention. Data were analyzed using mean (SD), t-Test and analysis of variance. The mean (SD) scores at pre- and post-test were 2.7 ± 3 and 8.8 ± 1 out of 10, respectively. Paired t-tests demonstrated a significant difference in the pre- post-test knowledge scores. Increasing knowledge and promoting favorable attitudes of policy makers can lead to greater attention which could in turn change tobacco taxation policies.

Abstract Background Most of the care of HIV-infected patients is now provided in the clinic where there is less time for bedside teaching than in the inpatient setting. We sought to augment the clinical experience by developing an HIV-focused e-learning flipped classroom curriculum in our ID fellowship program. Methods Six e-learning modules were developed using Articulate Storyline. Topics included: HIV Diagnosis, Evaluation of the HIV-infected Patient, When to Start Antiretroviral Therapy, What to Start, HIV Resistance, and HIV Drug-Drug Interactions. Modules were made available 1 week in advance, lasted 20 minutes, and included interactive questions. Class time was spent discussing clinical cases related to the module. The IDSA “HIV Medicine in Clinical Practice” exam and pre and post-course surveys were administered to measure changes in both objective and self-perceived knowledge before and after completion of the curriculum. Wilcoxon-signed rank test was used to compare test results between the 2 periods. Results Seven fellows participated in the curriculum and 10 fellows completed the pre and post-tests (3 fellows tested only with pretest as they were finishing fellowship, 4 fellows took both pre and post- test, and 3 fellows only took the post-test). Overall scores between pre-and post-test were not significantly different between pooled pre- and post-test results (7 fellows took each test) (P = 0.8). Among the 4 fellows who completed both tests, there was a trend to improved scores (P = 0.06). 7 of 7 fellows completed the pre- and post-curriculum surveys. All agreed or strongly agreed that the flipped classroom model enhanced their learning of the material and self-perceived knowledge improved in all assessed areas following participation in the curriculum (see Figure). Conclusion The introduction of the e-learning modules in a flipped classroom format was well received by fellows and allowed for better preparation and discussion of HIV-related topics. Although pre-and post-test results were unchanged, self-perceived confidence in clinical skills improved for all fellows. The flipped classroom might be a promising method to enhance HIV-focused clinical education for fellows. Disclosures All authors: No reported disclosures.

The purpose of this study was to compare the efficacy of simulation versus lecture-based education among preclinical medical students. Twenty medical students participated in this randomized, controlled crossover study. Students were randomized to four groups. Each group received two simulations and two lectures covering four different topics. Students were administered a pre-test, post-test and delayed post-test. The mean percentage of questions answered correctly on each test was calculated. The mean of each student's change in score across the three tests was used to compare simulation- versus lecture-based education. Students in both the simulation and lecture groups demonstrated improvement between the pre-test and post-test (p < 0.05). Students in the simulation group demonstrated improvement between the immediate post-test and delayed post-test (p < 0.05), while students in the lecture group did not demonstrate improvement (p > 0.05). When comparing interventions, the change in score between the pre-test and post-test was similar among both the groups (p > 0.05). The change in score between the post-test and delayed post-test was greater in the simulation group (p < 0.05). High-fidelity simulation may serve as a viable didactic platform for preclinical medical education. Our study demonstrated equivalent immediate knowledge gain and superior long-term knowledge retention in comparison to lectures.

2007-01-01

Background A randomized, double-blind, placebo-controlled study was performed to evaluate the effect of oral phosphatidylserine (PS) supplementation on golf performance in healthy young golfers with handicaps of 15–40. Methods Perceived stress, heart rate and the quality of the ball flight was evaluated before (pre-test) and after (post-test) 42 days of 200 mg per day PS (n = 10) or placebo (n = 10) intake in the form of a nutritional bar. Subjects teed-off 20 times aiming at a green 135 meters from the tee area. Results PS supplementation significantly increased (p < 0.05) the number of good ball flights (mean: pre-test 8.3 ± 3.5, post-test 10.1 ± 3.0), whereas placebo intake (mean: pre-test 7.8 ± 2.4, post-test 7.9 ± 3.6) had no effect. PS supplementation showed a trend towards improving perceived stress levels during teeing-off (mean: pre-test 5.8 ± 2.0, post-test 4.0 ± 2.0, p = 0.07), whereas stress levels remained unchanged in the placebo group (mean: pre-test: 5.1 ± 2.0, post-test: 5.1 ± 3.1). Supplementation did not influence mean heart rate in either group. Conclusion It is concluded that six weeks of PS supplementation shows a statistically not significant tendency (p = 0.07) to improve perceived stress levels in golfers and significantly improves (p < 0.05) the number of good ball flights during tee-off which might result in improved golf scores.

Before interventions are implemented, the potential treatment benefit must be determined. The primary objective of this feasibility study was to assess if peers' attitudes towards children who stutter (CWS) change one month after the administration of the Classroom Communication Resource (CCR). The secondary objectives of the study were to determine if differences in peer attitudes were related to gender and to previous exposure to a person who stutters. The study used a cluster randomised control trial design. The study included 211 Grade 7 participants from schools in the Cape Town Metropole. The CCR intervention was administered to 97 participants in the experimental group, whilst 114 participants in the control group did not receive the intervention. The Stuttering Resource Outcome Measure(SROM) used as the outcome measure during pre- and post-test period. STATISTICA was used for in-depth data analysis. An overall positive direction of change in scores was observed for the experimental group compared with the control group. However, the magnitude of change in the experimental group was not statistically significant (p = 0.2683). Male and female participants did not differ significantly in their scores on the SROM across pre-test and post-test periods. Participants who had exposure to individuals who stutter had significantly more positive scores on the SROM in the pre-test and post-test periods compared to those who had no direct exposure to stuttering. This result indicated the beginning of positive attitude change which may be attributed to the intervention. Further investigation is warranted.

Desk-based employees face multiple workplace health hazards such as insufficient physical activity and prolonged sitting. The objective of this study was to increase workday energy expenditure by interrupting prolonged occupational sitting time and introducing short-bursts of physical activity to employees' daily work habits. Over a 13-week period participants (n=17) in the intervention group were regularly exposed to a passive prompt delivered through their desktop computer that required them to stand up and engage in a short-burst of physical activity, while the control group (n=17) was not exposed to this intervention. Instead, the control group continued with their normal work routine. All participants completed a pre- and post- intervention survey to estimate workplace daily energy expenditure (calories). There was a significant 2 (Group) × 2 (Test) interaction, F (1, 32)=9.26, p < 0.05. The intervention group increased the calories expended during the workday from pre-test (M=866.29 ± 151.40) to post-test (M=1054.10 ± 393.24), whereas the control group decreased calories expended during the workday from pre-test (M=982.55 ± 315.66) to post-test (M=892.21 ± 255.36). An e-health intervention using a passive prompt was an effective mechanism for increasing employee work-related energy expenditure. Engaging employees in regular short-bursts of physical activity during the workday resulted in reduced sitting time, which may have long-term effects on the improvement of employee health.

Two microcosm-scale wetlands (570-liter containers) were integratively designed and constructed to investigate transfers and transformations of zinc associated with an aqueous matrix, and to provide future design parameters for pilot-scale constructed wetlands. The fundamental design of these wetland microcosms was based on biogeochemical principles regulating fate and transformations of zinc (pH, redox, etc.). Each wetland consisted of a 45-cm hydrosoil depth inundated with 25 cm of water, and planted with Scirpus californicus. Zinc ( approximately 2 mg/liter) as ZnCl2 was amended to each wetland for 62 days. Individual wetland hydraulic retention times (HRT) were approximately 24 h. Total recoverable zinc was measured daily in microcosm inflow and outflows, and zinc concentrations in hydrosoil and S. californicus tissue were measured pre- and post-treatment. Ceriodaphnia dubia and Pimephales promelas7-day aqueous toxicity tests were performed on wetland inflows and outflows, and Hyalella azteca whole sediment toxicity tests (10-day) were performed pre- and post-treatment. Approximately 75% of total recoverable zinc was transferred from the water column. Toxicity decreased from inflow to outflow based on 7-day C. dubia tests, and survival of H. azteca in hydrosoil was >80%. Data illustrate the ability of integratively designed wetlands to transfer and sequester zinc from the water column while concomitantly decreasing associated toxicity. Copyright 1999 Academic Press.

Designing instruction to support mechanical reasoning: Three alternatives in the simple machines learning environment

NASA Astrophysics Data System (ADS)

McKenna, Ann Frances

2001-07-01

Creating a classroom environment that fosters a productive learning experience and engages students in the learning process is a complex endeavor. A classroom environment is dynamic and requires a unique synergy among students, teacher, classroom artifacts and events to achieve robust understanding and knowledge integration. This dissertation addresses this complex issue by developing, implementing, and investigating the simple machines learning environment (SIMALE) to support students' mechanical reasoning and understanding. SIMALE was designed to support reflection, collaborative learning, and to engage students in generative learning through multiple representations of concepts and successive experimentation and design activities. Two key components of SIMALE are an original web-based software tool and hands-on Lego activities. A research study consisting of three treatment groups was created to investigate the benefits of hands-on and web-based computer activities on students' analytic problem solving ability, drawing/modeling ability, and conceptual understanding. The study was conducted with two populations of students that represent a diverse group with respect to gender, ethnicity, academic achievement and social/economic status. One population of students in this dissertation study participated from the Mathematics, Engineering, and Science Achievement (MESA) program that serves minorities and under-represented groups in science and mathematics. The second group was recruited from the Academic Talent Development Program (ATDP) that is an academically competitive outreach program offered through the University of California at Berkeley. Results from this dissertation show success of the SIMALE along several dimensions. First, students in both populations achieved significant gains in analytic problem solving ability, drawing/modeling ability, and conceptual understanding. Second, significant differences that were found on pre-test measures were eliminated on post-test measures. Specifically, female students scored significantly lower than males on the overall pre-tests but scored as well as males on the same post-test measures. MESA students also scored significantly lower than ATDP students on pre-test measures but both populations scored equally well on the post-tests. This dissertation has therefore shown the SIMALE to support a collaborative, reflective, and generative learning environment. Furthermore, the SIMALE clearly contributes to students' mechanical reasoning and understanding of simple machines concepts for a diverse population of students.

A total of one hundred twenty-nine respondents (129) were involved in the study, one hundred twenty-four (124) of the respondents were Grade 7 students, two (2) biology in-service teachers from Integrated Developmental School, MSUIIT, two (2) ICT experts from MSU-IIT, and one in-service biology teacher from Iligan City National High School. The study employed was a Quasi-experimental design with two-group (experimental and control groups) pre-test-post-test design. The instruments used were a 20-item multiple choice tests for the pre-test and post-test and a rubric for the evaluation of the Cell Story eBook. The researchers developed the Cell story eBook through a pre-assessment, identification of the topic, formulation of objectives, making of the story, making of the storyboard, designing of the Cell story eBook, evaluation of the Cell story eBook, final revision and publication in PDF format. During the utilization stage, the experimental group was presented with the Cell story eBook through storytelling while the control group was taught using traditional lecture method. Findings show that the developed Cell story eBook was rated Excellent by the panel of experts. Moreover, there is a statistically significant difference between the post-tests of the two groups. Results signifies that there is a distinction between the performances of the two groups which means that there is an existing impact after the utilization of the developed Cell story eBook through storytelling inside the classroom. The said developed instructional material and the way it was utilized therefore, affects the conceptual knowledge of the learners. The developed Cell story eBook can also be utilized even in the absence of technology due to its flexibility. It can be printed as a hard copy for further utilization especially for those schools that still lacks appropriate learning facilities which is a common situation in the Philippines.

No treatments are currently available that slow, stop, or reverse disease progression in established multiple sclerosis (MS). The Mesenchymal Stem Cells in Multiple Sclerosis (MSCIMS) trial tests the safety and feasibility of treatment with a candidate cell-based therapy, and will inform the wider challenge of designing early phase clinical trials to evaluate putative neuroprotective therapies in progressive MS. Illustrated by the MSCIMS trial protocol, we describe a novel methodology based on detailed assessment of the anterior visual pathway as a model of wider disease processes--the "sentinel lesion approach". MSCIMS is a phase IIA study of autologous mesenchymal stem cells (MSCs) in secondary progressive MS. A pre-test : post-test design is used with healthy controls providing normative data for inter-session variability. Complementary eligibility criteria and outcomes are used to select participants with disease affecting the anterior visual pathway. Ten participants with MS and eight healthy controls were recruited between October 2008 and March 2009. Mesenchymal stem cells were successfully isolated, expanded and characterised in vitro for all participants in the treatment arm. In addition to determining the safety and feasibility of the intervention and informing design of future studies to address efficacy, MSCIMS adopts a novel strategy for testing neuroprotective agents in MS--the sentinel lesion approach--serving as proof of principle for its future wider applicability.

Pediatric Vascular Access Peripheral IV Algorithm Success Rate.

PubMed

Hartman, Jane H; Baker, John; Bena, James F; Morrison, Shannon L; Albert, Nancy M

Determine if the pediatric peripheral vascular access algorithm (PPVAA) led to differences in first-attempt and overall peripheral intravenous (PIV) success, staff attempting PIV access per episode and overall attempts and first PIV attempt success by provider. A two-cohort pre-/post-implementation comparative design involved pediatric nurses and patients. The PPVAA included four components: a patient comfort plan, PIV grading score, nurses' self-assessed IV access capability and nurse decision to stop-the-line. Two sample t-test or Wilcoxon rank sum test and Pearson's chi-square test were used to evaluate differences between groups and measures. Healthcare providers (N=96) attempted 721 PIV insertions (pre-PPVAA, n=419 and post-PPVAA, n=302). Of 78 nurse providers, mean (SD) age was 37.4 (11.0) years and 20.0% self-assessed PIV capability as expert. Of children, mean age was 8.3 (7.0) years. Post-PPVAA, first-attempt (p=0.86) and overall (p=0.21) success did not change, though fewer staff were needed per episode to initiate PIV; p=0.017. Overall rate of success after one attempt in the post-PPVAA period compared to pre-PPVAA was reduced (p=0.002), reflecting greater awareness to stop-the-line. Compared to pre-PPVAA, advanced practice nurses and non-clinician providers were more likely to achieve success on first attempt. The PPVAA did not increase first-attempt or overall PIV success; however, it decreased overall IV attempts and the number of staff attempting access per episode. The multi-component PPVAA provided a guide for nurses during PIV and assisted decision making to stop attempts in difficult cases. Copyright © 2017 Elsevier Inc. All rights reserved.

Using Video Games to Support Pre-Service Elementary Teachers Learning of Basic Physics Principles

The purpose of this work is to share our findings in using video gaming technology to facilitate the understanding of basic electromagnetism with pre-service elementary teachers. To this end we explored the impact of using a game called Supercharged! on pre-service teachers' understanding of electromagnetic concepts compared to students who conducted a more traditional inquiry oriented investigation of the same concepts. This study was a part of a larger design experiment examining the pedagogical potential of Supercharged! the control group learned through a series of guided inquiry methods while the experimental group played Supercharged! during the laboratory sections of the science course. There was significant difference F(2,134) = 4.8, p < 0.05, η2 = 0.59 between the control and experimental groups on the gains from pre-to-post assessment with an effect size of d = 0.72. However, while students in the experimental group performed better than their control group peers, they rated their knowledge of the topic lower than the control group ( M post-control = 3.0, M post-experiment = 2.7), leading to further examination of their laboratory journals. Results of this study show that video games can lead to positive learning outcomes, as demonstrated by the increase in test scores from pre- to post-assessment. Additionally, this study also suggests that a complementary approach, in which video games and hands-on activities are integrated, with each activity informing the other, could be a very powerful technique for supporting student scientific understanding. Further, our findings suggest that video game designers should embed meta-cognitive activities such as reflective opportunities into educational video games to provide scaffolds for students and to reinforce that they are engaged in an educational learning experience.

This study will extend on a pilot study and will evaluate the impact of a novel approach to PE, Better Movers and Thinkers (BMT), on students' cognition, physical activity habits, and gross motor coordination (GMC). The study will involve six mainstream state schools with students aged 9–11 years. Three schools will be allocated as the intervention condition and three as the control condition. The design of the study is a 16-week intervention with pre-, post- and 6 month follow-up measurements taken using the ‘Cognitive Assessment System (CAS)’ GMC tests, and the ‘Physical Activity Habits Questionnaire for Children (PAQ-C).’ Qualitative data will be gathered using student focus groups and class teacher interviews in each of the six schools. ANCOVA will be used to evaluate any effect of intervention comparing pre-test scores with post-test scores and then pre-test scores with 6 month follow-up scores. Qualitative data will be analysed through an iterative process using grounded theory. This protocol provides the details of the rationale and design of the study and details of the intervention, outcome measures, and the recruitment process. The study will address gaps within current research by evaluating if a change of approach in the delivery of PE within schools has an effect on children's cognition, PA habits, and GMC within a Scottish setting.

This study aimed to determine the effects of a plant cultivation-based horticultural therapy program for elderly people with mental health problems. Pre- and post-test design with experimental and control groups. Twenty-eight elderly Korean people with mental health problems participated from April to June 2017 at a farm located in Suwon, South Korea. The participants were randomly assigned to either the control (n = 14) or horticultural therapy group (n = 14); the latter participated in once-weekly sessions of a previously designed 10-session horticultural therapy program. The pre-test occurred 1 week before starting the horticultural therapy program. The post-test was completed within 1 week after finishing the final program session. Cortisol levels were measured in saliva samples collected from both groups. The Senior Fitness Test was used to assess physical functional ability in both groups. In the horticultural therapy group, the cortisol levels decreased significantly from before to after the horticultural therapy program, and the post-test scores for six subtests of the Senior Fitness Test improved significantly. No significant improvements were seen in either measure in the control group. This study demonstrates the potential ability of horticultural therapy to improve the stress levels and physical functional abilities of elderly people with mental health problems. In future studies, it would be interesting to verify the long-term effects of this horticultural therapy program and to compare its effects with regard to sex, age, and various mental symptoms.

To investigate the hydration status pre- and post-training among university athletes using urine color and weight loss as indicators. Participants were 52 university athletes training for campus games in a developing country. Pre- and post-training urine specimens were compared with a standard urine color scale. Paired t tests were used to compare urine color and difference in body mass pre- and post-training. The mean age of the athletes was 22.87 ± 3.21. A statistically significance difference (p < .01) was observed between pre- (4.31 ± 1.75) and post- (5.67 ± 1.45) training urine color values for males. Hydration status and weight post-training were statistically significantly different both at the level of p < .01. The results suggest that there is a link between urine color and body mass difference among the student athletes tested. Exercise increases hypohydration due to fluid losses, and therefore attention should be given to fluid supplementation and individualization of fluid intake for each athlete.
