The Psychometric Properties of the Posttraumatic Stress Disorder Checklist for the DSM‐5 in Korean Adults Exposed to Natural Disasters^1,2

Abstract

This study was conducted to examine the factor structure and other psychometric properties of the Posttraumatic Stress Disorder Checklist for the Diagnostic and Statistical Manual Disorders-Fifth Edition (PCL-5) in Korean adults (N = 234) exposed to natural disasters. Confirmatory factor analyses indicated almost the same excellent fit with both the six-factor Anhedonia model and the seven-factor Hybrid model. However, no significant difference in model fit was found between the two models, supporting the parsimonious six-factor Anhedonia model. In addition, the total scale and six subscales of the PCL-5 demonstrated good or acceptable internal consistency and good convergent and discriminant validity. These results provide additional evidence for expanding the use of the PCL-5 with non-English-speaking adults exposed to natural disasters. Implications for the use of this questionnaire in assessment and treatment contexts are discussed.

Lessons From the Field Psychosocial consequences of the COVID‐19 homestay for preschoolers and their parents

“…Cronbach's alpha reliability coefficient for the PCL‐5 in this sample was 0.93. For symptoms of depression, we used the nine‐item Patient Health Questionnaire (PHQ‐9; Kroenke et al, 2001; Seo & Cho, 2021). Parents rated how often they were bothered by these problems over the past 2 weeks on a 4‐point scale that ranged from 0 ( not at all ) to 3 ( nearly every day ).…”

A psychometric evaluation of the National Stressful Events Survey for PTSD-Short Scale (NSESSS-PTSD) among Korean psychiatric outpatients

“…The Korean version used in this study showed high internal consistency, high test-retest reliability, and good concurrent validity among elderly Vietnam veterans (Kim et al, 2017 ). Additionally, it resulted in high internal consistency, good convergent validity with other PTSD measures, and discriminant validity against anxiety and depression among earthquake survivors (Seo & Cho, 2021 ). The Cronbach’s alpha for this study was .92 for PTSD group.…”

Physical and mental health characteristics related to trust in and intention to receive COVID-19 vaccination: results from a Korean community-based longitudinal study

“…In the online survey, sleep quality, anxiety, post-traumatic stress, depression, loneliness, and psychological resilience scale were included to assess current mental health status during the COVID-19 pandemic. The measurement tool for each mental health domain was as follows: sleep quality: the Korean version of the Pittsburgh Sleep Quality Index (PSQI-K; sensitivity, 0.94; specificity, 0.84) [ 27 ]; anxiety: Generalized Anxiety Disorder-7 (GAD-7; area under the curve, 0.91) [ 28 ]; post-traumatic stress: Post-traumatic Stress Disorder Checklist for the Diagnostic and Statistical Manual Disorders (fifth edition) (PCL-5; Cronbach’s α= 0.91) [ 29 ]; depression: Patient Health Questionnaire-9 (PHQ-9; Cronbach’s α= 0.81) [ 30 ]; loneliness: the short version of the UCLA Loneliness Scale (ULS-6) [ 31 ]. For all these instruments, a higher score indicates greater severity of each symptom.…”
