BackgroundInvestigating the psychometric properties of existing psychometric scales in societies with differing dynamics can help with their external validity. This research specifically aimed at standardization and validation of Interpersonal Sensitivity Measure (IPSM) scale in Iran.Materials And MethodsPersian version of the IPSM was produced through forward translation, reconciliation, and back translation. A total of 357, nonclinical students were selected through multistage sampling method and completed a set of questionnaires including IPSM. Internal consistency, convergent validity, divergent validity, and test-retest reliability of the Persian version of the IPSM were analyzed. To assess the construct validity, confirmatory factor analysis (CFA) was performed.ResultsTotal IPSM, as well as all subscales showed satisfactory internal consistency (Cronbach's α =0.86 and 0.51-0.71, respectively). Test-retest reliability at a 2-week interval was significant, with intraclass correlation coefficient ranging between 0.73 and 0.92. In terms of convergent validity, IPSM showed the significant positive correlation with self-report measures of depression, social anxiety, and anxious attachment style. IPSM showed negative correlation with Social Desirability Scale and secure (C subscale of avoidant attachment style [AAS]) and dependent (D subscale of AAS), thus demonstrated divergent validity with these constructs. According to the CFA, the responses of the sample in this study were fitted to the original five-factor structure.ConclusionThe IPSM showed good validity and reliability and could be useful in assessing interpersonal sensitivity in Iranian population.
