The Reliability and Validity of the Post-Traumatic Stress Disorder Checklist (PCL) in the Earthquake-Stricken Population of Kermanshah, Iran

Abstract

Background: The post-traumatic stress disruption checklist (PCL) is a reliable self-assessment measure for post-traumatic stress disorder (PTSD). Recently, the PCL has been updated based on the DSM-5 criteria for PTSD Objectives: The present study aimed to determine the psychometric properties and diagnostic capability of the PCL as a screening tool in an earthquake-stricken population in Kermanshah, Iran. Methods: This cross-sectional study was conducted on 200 injured earthquake victims in Sales and Javanrud counties. The subjects were selected via purposive sampling. The PCL was translated into Kurdish (Surani), and trained interviewers run the translated version for 200 individuals manifesting the symptoms of post-earthquake stress in the earthquake-stricken cities of Javanrud and Sales located in Kermanshah province. After two weeks, 100 participants were randomly selected, and the questionnaire was completed again. Results: The internal consistency of the PCL (α = 85%) was indicative of the validity of the checklist. The Youden’s index with the cutoff point of 23 was considered optimal for the PCL tool. The diagnostic values of sensitivity and specificity were estimated at 0.82 and 0.81, respectively (P < 0.001). In addition, the test-retest results were equal after two weeks (α = 87%), indicating the high reliability of the checklist. Conclusions: According to the results, the PCL is a sensitive and accurate tool for assessing the status of PTSD in disaster victims and accidents and could be used in the screening of PTSD in the health monitoring programs for these victims.
