“…We decided to retain the five-factor model because its fit indices best approached the "excellent fit" cutoffs described previously (Byrne, 2009;Hu & Bentler, 1999;Simms et al, 2002). Our findings on the factor structure of the PCL-S are consistent with those of several recent studies (Armour et al, 2012;Arnberg et al, 2014;Pietrzak et al, 2012). In addition, the correlations between the five factors were all very strong, which also coincides with the results of previous studies (Armour et al, 2012;.…”

Psychometric Evaluation of the Japanese Version of the Posttraumatic Stress Disorder Checklist in Community Dwellers Following the Fukushima Daiichi Nuclear Power Plant Incident

We investigated the psychometric properties of the Japanese version of the Posttraumatic Stress Disorder Checklist–Stressor Specific Version (PCL-S) using baseline data from the Fukushima Health Management Survey. A total of 26,332 men and 33,516 women aged 16 and above participated in this study. Participants lived in the Fukushima evacuation zone in Japan and experienced the Great East Japan Earthquake and nuclear power plant (NPP) incident. The PCL-S was used to assess participants’ posttraumatic stress disorder (PTSD) symptoms. In addition, we described participants and tested the validity of the PCL-S by administering the Kessler Six-item Screening Scale for Psychological Distress (K6) and assessing education; employment; self-rated health; sleep satisfaction; experiencing the earthquake, tsunami, and NPP incident; and bereavement as a result of the disaster. PCL-S scores exhibited a positively skewed, slightly leptokurtic distribution. Confirmatory factor analysis revealed that the five-factor model was a better fit than were the three- or four-factor models. The PCL-S and its subscales had high Cronbach’s alpha coefficients. The PCL-S scores had weak-to-moderate correlations with history of mental illness, bereavement, experiencing the tsunami, experiencing the NPP incident, self-rated health, and sleep satisfaction, as well as a strong correlation with psychological distress. There were significant gender and age differences in PCL-S scores. Overall, this study confirmed the psychometric properties of the PCL-S, including the score distribution, factor structure, reliability, validity, and gender and age differences. Thus, the Japanese version of the PCL-S would be a useful instrument for assessing the PTSD symptoms of community dwellers who have experienced traumatic events.

“…The Anhedonia model draws upon theoretical and empirical evidence that besides re-experiencing and avoidance, anxious and dysphoric arousal are two separate symptom clusters (Arnberg, Michel, & Johannesson, 2014; Witte, Domino, & Weathers, 2015), and negative affect and decreased positive affect or anhedonia are two unique constructs (Cuthbert & Kozak, 2013; Watson, 2005, 2009; Watson, Clark, & Stasik, 2011). Importantly, the six clusters of the Anhedonia model represent a further refinement within the clusters of the DSM-5 model for PTSD.…”

Background: In 2013, the Clinician-Administered PTSD Scale, the golden standard to assess PTSD, was adapted to the DSM-5 (CAPS-5).Objective: This project aimed to develop a clinically relevant Dutch translation of the CAPS-5 and to investigate its psychometric properties.Method: We conducted a stepped translation including Delphi rounds with a crowd of 44 Dutch psychotrauma experts and five senior psychotrauma experts. Using partial crowd-translations, two professional translations and the official Dutch translation of the DSM-5, each senior expert aggregated one independent translation. Consensus was reached plenary. After back-translation, comparison with the original CAPS-5 and field testing, a last round with the senior experts resulted in the final version. After implementation clinicians conducted CAPS-5 interviews with 669 trauma-exposed individuals referred for specialized diagnostic assessment. Reliability of the Dutch CAPS-5 was investigated through internal consistency and interrater reliability analyses, and construct validity through confirmatory factor analysis (CFA).Results: CAPS-5 total severity score showed high internal consistency (α = .90) and interrater reliability (ICC = .98, 95% CI: .94–.99). CAPS-5 diagnosis showed modest interrater reliability (kappa = .59, 95% CI: .20–.98). CFA with alternative PTSD models revealed adequate support for the DSM-5 four-factor model, but a six-factor (Anhedonia) model fit the data best.Conclusions: The Dutch CAPS-5 is a carefully translated instrument with adequate psychometric properties. Current results add to the growing support for more refined (six and seven) factor models for DSM-5 PTSD indicating that the validity and clinical implications of these models should be objective of further research.

“…properties of the IES-R, and its screening properties as compared to a structured clinical 18 interview, were examined in a randomly selected subset of participants who had been exposed 19 to the tsunami (Arnberg, Michel, & Johannesson, 2014). According to this study, the IES-R 20 demonstrated excellent psychometric properties as evidenced in longitudinal stability in both 21 its subscales and the screening threshold.…”
