a meta-analysis of the structural validity of original and brief versions of the personality inventory for dsm-5 in iran

Objective: the personality inventory for dsm-5 (pid-5) is a widely used scale to evaluate the dimensional constructs of two trait models proposed by the diagnostic and statistical manual of mental disorders (dsm-5) and the international classification of diseases (icd-11). the present meta-analysis first aimed to examine the factor structure, reliability, and congruence coefficients of the persian version of the pid-5 to assess both trait models. the second aim was to evaluate the factor structure and reliability of the persian version of the personality inventory for dsm-5-brief form (pid-5-bf).method: a systematic search was conducted in pubmed, magiran, and sid to find records in english and farsi from january 2013 to december 2023. according to the prisma, data from nine medium- to high-quality reports including 7,608 participants were analyzed using the random-effects method. quality of studies, heterogeneity, and publication bias were reported.results: the five-factor structure of the pid-5 to measure both trait models was supported by the pooled estimates of factor loadings. the alpha coefficient median for the dsm-5 model was 0.83 (range: 0.82-0.90), and the congruence coefficient median was .91 (range: 0.80-0.97). the icd-11 alpha median was .78 (range: 0.68-0.91), and congruency median was 0.90 (range: 0.71-0.96). the factor loadings for negative affectivity, detachment, antagonism, disinhibition, and psychoticism on the pid-5-bf were 0.44-0.69, 0.38-0.67, 0.46-0.72, 0.42-0.70, and 0.44-0.76, respectively, and the alpha median was 0.73 (range: 0.65-0.76).conclusion: since both the original and brief versions of the pid-5 are valid and strongly similar to international structures, the clinical and research applications of these questionnaires are recommended to mental health professionals in iran.
