| Abstract | Background: The Short Index of Self-Actualization (SISA) is a self-report measure used to evaluate an individual’s degree of self-actualization tendencies. Objectives: This study aimed to investigate the psychometric properties of Jones and Crandall’s SISA within an Iranian population. Methods: A sample of 466 individuals was selected using a convenience random sampling method. Participants completed the SISA, Ambiguity Tolerance Scale, Rosenberg Self-Esteem Scale, and Rational Behavior Inventory (RBI). Internal consistency coefficients, along with exploratory and confirmatory factor analyses, were employed to examine the data. Analyses were conducted using SPSS 25 and AMOS software. Results: The findings indicated that the internal consistency coefficient for this questionnaire across all components exceeded 0.70, suggesting the appropriateness of the tool. Exploratory factor analysis (EFA) accounted for 0.47% of the variance. Confirmatory factor analysis (CFA) supported the five-factor structure of the SISA, which includes autonomy or self-direction, self-acceptance and self-esteem, avoidance of unpleasant experiences, trust and responsibility in interpersonal relations, and acceptance of emotions, in the Iranian sample [root mean square error of approximation (RMSEA) = 0.062, CFI = 0.919, NFI = 0.94]. The correlation coefficient results indicated a significant negative relationship between elements of ambiguity tolerance, while a significant positive relationship was found between aspects of rational behavior and self-esteem with self-actualization (P < 0.0001). Conclusions: The Persian version of the SISA is a reliable and valid instrument for assessing self-actualization in the Iranian population, providing researchers and practitioners with a useful self-assessment scale. | en |
