This study aimed to investigate the validity and factor structure of the Self-Assessed Wisdom Scale (SAWS; Webster in J Adult Dev 10:13–22, 2003) in an Iranian population. Participants (235 male, 340 female) were recruited in Tehran, Iran and ranged in age from 17 to 88 years. Cronbach alpha’s for the subscales ranged from .63 to .81, and their inter-correlations ranged from .42 to .53. Exploratory factor analysis extracted 5 factors that were similar with the original structure. Confrmatory factor analysis supported 5-factor model of the SAWS. The SAWS’s total and subscale scores positively correlated with two other measures of wisdom (indicating convergent validity). The SAWS correlated weakly with age. Women scored higher in the SAWS subscales of emotional regulation, reminiscence/refectiveness, and humor, which accounted for a signifcant gender diference in total wisdom. Although the age diferences are consistent with prior research, the gender diferences are relatively novel. Overall, results indicate that the SAWS has excellent psychometric properties and can be used in cross-cultural work.
