The present research aims to study the consistency between the Personality Psychopathology Five (PSY-5) scales and DSM-IV axis II. The study was a questionnaire survey research applying methodological and testing methods. First, the experimental background of the Iranian data for PSY-5 as well as the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) were studied. Then, the consistency between PSY-5 and DSM-5 was investigated in a multivariate environment through examining the joint factor analysis of PSY-5 and PID-5. The data were collected using MMPI-2-RF and PID-5 questionnaires. The sample population included 793 (student, non-student, and clinical) subjects selected from among all people older than 16 in Tehran. At the end, 452 protocols of the answered items were recognized as valid for doing statistical analysis. Depending on the research questions, the methods of question categorization, exploratory factor analysis, principal component analysis with varimax rotation, common factor analysis, maximum-likelihood estimation with varimax rotation, Horn's parallel analysis, confirmatory factor analysis, goodness of fit index (GFI), X2 / d. f. ratio, adjusted goodness of fit index (AGFI), comparative fit index (CFI), root mean square error of approximation (RMSEA), and SPSS and AMOS software. The results were indicative of a good fitness of the research data with confirmatory factor analysis models for both PSY-5 and PID-5 scales. The results of the common exploratory factor analysis also confirmed the hypothesis, and showed that each scale of PSY-5 had a significant factor loading in the expected areas of DSM-5.
