An Updated Validation of Persian Versions of Six Personality Questionnaires: TEMPS-A, AFECTS, TCI, PANAS, NEO-FFI, PDQ-4

Abstract

Background:The revision and updating of questionnaires are part of the list of comprehensive guidelines for using psychological questionnaires. The present study aimed to test the construct and convergent validity of the Persian versions of six personality questionnaires including the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A: 35 items), the Affective and Emotional Composite Temperament Scale (AFECTS: 48 items), the Temperament and Character Inventory (TCI: 125 items), the Positive Affect and Negative Affect Schedule (PANAS: 20 items), the NEO-Five-Factor Inventory (NEO-FFI: 60 items), and Personality Diagnostic Questionnaire-4 (PDQ-4: 99 items).Methods:The data from four independent samples of Iranian adults ( N1 = 1137, N2 = 558, N3 = 496, N4 = 478; total N = 2669, 70% female, 32.8 ± 10.7 old years) were analyzed by exploratory structural equation modeling (ESEM). Pearson correlations between constructs of the Personality Inventory for DSM-5-Short Form (PID-5-BF: 25 items) or the ICD-11 compatible Personality Inventory for DSM-5–Brief Form Plus, Modified (PID5BF+M: 36 items) and the personality measures were used to evaluate convergent validity.Results:Although the number of factors of TEMPS-A and PDQ-4 were slightly different from the original structures, the results supported the factor structure and reliability (all α between 0.68 and 0.92) of all measures. Most factors of all measures were significantly related to either the PID-5-BF or the PID5BF+M constructs (all P <.05).Conclusion:The findings supported both construct validity and convergent validity of all personality measures in Iranian samples. Mental health professionals can use the Persian version of all valid personality measures to draw personality profiles of adult populations.
