AIM : Although various aspects of guilt are frequent problems of patients suffering from PTSD, they have been included into the diagnostic criteria for PTSD just in the present version DSM-5. Kubany proposed a cognitive conceptualization of guilt in PTSD followed by development of the Trauma Related Guilt Inventory (TRGI). The aim of the paper is to present psychometric properties of the Polish version of the inventory - the TRGI-PL. A Polish adaptation of the Trauma-Related Guilt Inventory was applied to a sample of 280 motor vehicle (MVA) participants (147 females, 133 males of age from 18 to 80 (M=34,93, SD=13,71) within 1-24 months after a MVA (M=10,18, SD=6,23). Validation of the Polish version was done by analyzing the internal structure of the instrument and comparing the emotional and cognitive aspects of guilt assessed by the TRGI with PTSD symptoms, post-traumatic cognitions and responsibility for MVA and subjective agreement with the judgment. The model with four latent factors: Distress, Hindsight-Bias/Responsibility, Wrongdoing and Insufficient Justification scales showed acceptable fit (Satorra-Bentler chi2=518,62, df=203, p<0,01, RMSEA=0,079, CFI=0,96, GFI=0,97), what confirms the four-factor structure of guilt, obtained in the studies on original TRGI version. Reliability coefficients are similar to original version. Correlations with other PTSD measures showed satisfactory convergent and discriminative validity. The Polish adaptation of the Trauma-Related Guilt Inventory is a reliable and valid tool for assessing guilt as a multidimensional phenomenon, comprising emotional and several cognitive characteristics, in trauma survivors.

Introduction: The Kaali Impact Crater on the island of Saaremaa, Estonia (58.37° N, 22.67° E) is part of a crater-strewn-field consisting of nine identified craters, ranging in size from 110m (Kaali Main) to a few meters in diameter [1-3]. The strewn field was formed by the breakup of an IAB iron meteorite during atmospheric entry [4]. The main crater is due to its size an important crater to study the effects of small asteroidal impacts on terrestrial planets. Despite some anthropomorphic changes, the crater is well preserved. During a scientific expedition in August 2014, we mapped the crater in unprecedented detail using 3D laser scanning tools and made detailed strike and dip measurements of all outcrops. Additional measurements using ground-penetrating radar and electro-resistivity tomography we also conducted to further refine the subsurface crater morphology. The results include a high resolution topographic map of the crater, previously unreported observations of overturned ejecta, and refined morphometric estimates of the crater. Additionally, research conducted as part of the expedition has provided a new, best-estimate for the formation of the crater (3200a +/- 30 BP) based on 14C AMS dating of charcoal from within the ejecta blanket [Losiak et al., 2015, this conference]. Structural Mapping: Although Kaali Main has been the subject of previous investigation (e.g. [2,5,6]), most of the structural descriptions of the crater pre-date modern crater investigations. Strongly inclined blocks were previously considered being affected by erosion and slope processes, our new observations show that most high dip-angle features fit well with overall dip-angle systematics. The existence of the overturned flap can be demonstrated in at least four areas around the crater. 3D Laser Scanning: A point cloud containing 16 million data points was created using 43 individual scans from a tripod mounted Faro 3D 330x laser scanner. Scans were processed using Trimble Realworks software. A DEM, Hillshade, Slope Map and Contour Map were created in ESRI ArcScene software. Photogrammetry: Photogrammetric techniques from images of key outcrops were used to create texture, photorealistic 3D representations using Agisoft PhotoScan software. Acknowledgements: We extend our sincerest gratitude to the Estonian National Heritage Board for permission to dig and make measurements at the crater. References: [1] I.Kolkun (1922) Üldine geologia.
