The Greek version of the Davidson Trauma Scale (DTS) was developed to respond to the need of Greek-speaking individuals. The translated questionnaire was administered to 128 HIV outpatients (aged 37.1±9.1) and 166 control patients (aged 32.4±13.4). In addition to the DTS Greek scale, subjects were assessed with two other scales useful for assessing validity. For each factor analyses two components were extracted, based on Cattell’s scree test. The two components solution accounted for 55.34% of the total variation in case of frequency variables and 61.45% in case of severity variables. The Cronbach’s alpha coefficient and Guttman split-half coefficient of the DTS scale were 0.93 and 0.88 respectively. The test-retest reliability of the Greek version of DTS scale proved to be satisfactory. Individual items had good intra-class correlation coefficients higher than 0.5, which means that all questions have high levels of external validity. The psychometric strength of interview for posttraumatic stress disorder-Greek version it’s reliable for its future use, particularly for screening subjects with possible diagnosis of posttraumatic stress disorder.

Abstract Background: Posttraumatic Stress Disorder (PTSD) is one of the most prevalent psychopathologies experienced by victims following natural disasters. The severity of traumatic experience may be a critical risk factor for the development of PTSD. Nevertheless, other factors may also lead to PTSD. We propose that fear and self-disclosure could be two important factors. Previous studies have examined their unique roles in PTSD, but their combined role in PTSD has been rarely assessed. To fill this gap, the aim of this study was to examine the relationship between severity of traumatic exposure, fear, self-disclosure, and PTSD among victims following flood disaster. Methods: one hundred ninety-nine participants completed self-report questionnaires. Descriptive statistics were obtained using SPSS 17.0 and Pearson correlation coefficients were calculated to obtain correlations between major variables. Results: results indicated that severity of traumatic exposure not only had a direct effect on PTSD, but also it had an indirect effect on PTSD via activating victims’ fear. Moreover, self-disclosure played a buffering role between fear and PTSD. However, the role of fear in PTSD may decrease with increases in levels of self-disclosure. Conclusions: Traumatic exposure had positive predictive effects for PTSD and fear. Self-disclosure had negative predictive effects for PTSD. Fear played a mediating role between severity of traumatic exposure and PTSD, self-disclosure played a moderating role in the relationship between fear and PTSD. Psychological interventions should focus on the regulation of fear and improvement of self-disclosure following traumatic exposure.

Abstract Background Children exposed to natural disasters are vulnerable to developing posttraumatic stress disorder (PTSD). Previous studies using resting-state functional neuroimaging have revealed alterations in graph-based brain topological network metrics in pediatric PTSD patients relative to healthy controls (HC). Here we aimed to apply deep learning (DL) models to neuroimaging markers of classification which may be of assistance in diagnosis of pediatric PTSD. Methods We studied 33 pediatric PTSD and 53 matched HC. Functional connectivity between 90 brain regions from the automated anatomical labeling atlas was established using partial correlation coefficients, and the whole-brain functional connectome was constructed by applying a threshold to the resultant 90 * 90 partial correlation matrix. Graph theory analysis was used to examine the topological properties of the functional connectome. A DL algorithm then used this measure to classify pediatric PTSD vs HC. Results Graphic topological measures using DL provide a potentially clinically useful classifier for differentiating pediatric PTSD and HC (overall accuracy 71.2%). Frontoparietal areas (central executive network), cingulate cortex, and amygdala contributed the most to the DL model’s performance. Conclusions Graphic topological measures based on fMRI data could contribute to imaging models of clinical utility in distinguishing pediatric PTSD from HC. DL model may be a useful tool in the identification of brain mechanisms PTSD participants.

Test Retest Reliability

The Self-rating Inventory for Posttraumatic Stress Disorder is a 22-item self-report questionnaire to give a diagnosis for PTSD based on DSM–IV criteria. Originally, the questionnaire was standardized with trauma survivors and psychiatric patients. Here test-retest reliabilities with 90 medial students are reported for 15 (.79) and 19 days (.97). As expected, the stability was slightly less for 34 days (.60)

Abstract Background Eye-tracking-based attentional research implicates sustained attention to threat in posttraumatic stress disorder (PTSD). However, most of this research employed small stimuli set-sizes, small samples that did not include both trauma-exposed healthy participants and non-trauma-exposed participants, and generally failed to report the reliability of used tasks and attention indices. Here, using an established eye-tracking paradigm, we explore attention processes to different negatively-valenced cues in PTSD while addressing these limitations. Methods PTSD patients (n = 37), trauma-exposed healthy controls (TEHC; n = 34), and healthy controls (HC; n = 30) freely viewed three blocks of 30 different matrices of faces, each presented for 6 s. Each block consisted of matrices depicting eight negatively-valenced faces (anger, fear, or sadness) and eight neutral faces. Gaze patterns on negative and neural areas of interest were compared. Internal consistency and test-retest reliability were evaluated for the entire sample and within groups. Results The two trauma-exposed groups dwelled longer on negatively-valenced faces over neutral faces, while HC participants showed the opposite pattern. This attentional bias was more prominent in the PTSD than the TEHC group. Similar results emerged for first-fixation dwell time, but with no differences between the two trauma-exposed groups. No group differences emerged for first-fixation latency or location. Internal consistency and 1-week test-retest reliability were adequate, across and within groups. Conclusions Sustained attention on negatively-valenced stimuli emerges as a potential target for therapeutic intervention in PTSD designed to divert attention away from negatively-valenced stimuli and toward neutral ones.

The Self-rating Inventory for Posttraumatic Stress Disorder of 22 items was developed for use with populations without identified traumatic experiences. The inventory has been used extensively in survey research in The Netherlands. This paper examines the psychometric properties. In four different groups (trauma and psychiatric patients, elderly Dutch subjects, former peacekeepers, and medical students) internal consistency, test-retest reliability, concurrent and discriminant validity, and sensitivity and specificity are analyzed. The inventory showed good internal consistency, test-retest reliability, concurrent and discriminant validity, and high sensitivity and specificity. It appears to be valuable for survey research on posttraumatic stress in nonselected populations. As a screening device, high sensitivity for PTSD symptoms is evident even when the traumatic event has not been defined.
