Psychometric Properties of the Persian Translation of the Sexual Quality of Life-Male Questionnaire

Sexual dysfunction has been demonstrated to be related to a poor quality of life. These dysfunctions are especially prevalent among men. This cross-sectional study aimed to investigate the psychometric properties of the Persian translation of the Sexual Quality of Life-Male (SQOL-M), translated and adapted to measure sexual quality of life among Iranian men. Forward-backward procedures were applied in translating the original SQOL-M into Persian, and then the psychometric properties of the Persian translation of the SQOL-M were studied. A total of 181 participants (23-60 years old) were included in the study. Validity was assessed by construct validity using confirmatory factor analysis, convergent validity, and content validity. The international index of erectile function (IIEF) and the work ability index were used to study the convergent validity. Reliability was evaluated through internal consistency and test-retest reliability analyses. The results from confirmatory factor analysis confirmed a one-factor solution for the Persian version of the SQOL-M. Content validity of the translated measure was endorsed by 10 specialists. Pearson correlations indicated that work ability index score, dimensions of the IIEF, and the IIEF total score were positively correlated with the Persian version of the SQOL-M (p < .001). Reliability evaluation indicated a high internal consistency and test-retest reliability. The Cronbach's alpha coefficient and intraclass correlation coefficients were .96 and .95, respectively. Results indicated that the Persian version of the SQOL-M has good to excellent psychometric properties and can be used to assess the sexual quality of life among Iranian men.
