Abstract

Background and Aim: The Personality Inventory for DSM–5 (PID–5) was created to aid a trait-based diagnostic system for personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM–5]). Given the need for access to reliable diagnostic instruments of mental disorders in Persian language for military personnel, the present study was designed to translate and determine the reliability and internal consistency of the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders-5th Edition (PID-5) instrument in soldiers.
Methods: This study had a cross-sectional design. The research sample was 401 Iranian army soldiers. PID-5 was translated via forward and backward translation method (English-Persian). Soldiers then completed the questionnaire. The data were analyzed by SPSS-16.
Results: Total Cronbach's alpha coefficient for Traits and Domains was 0.93 and 0.88, respectively. The range of obtained Cronbach's alpha for 24 facets were 0.60 to 0.82. which is considered acceptable and the lowest alpha was observed for suspiciousness (0.50). The range of Cronbach's alpha coefficient for Domains was 0.71 (Antagonism) to 0.84 (Psychoticism).
Conclusion: The Persian version of PID-5 instrument had good reliability and internal consistency for the evaluation of personality traits. PID-5 may be used with confidence in the research and diagnosis of personality traits in the military setting.
