Psychometric Properties of Sex Addiction Screening Test-Revised (SAST-R) for Persian Population
Background and Objectives: Sexual addiction is known as a disorder that afflicts a person with difficulty in controlling or delaying sexual behaviors. In order to prevent social, physical, and psychological consequences, validated screening tests are needed to diagnose this disorder. One of these tests is established by Carnes with the name of “Sexual Addiction Screening Test-Revised” (SAST-R). In this study, Sexual Addiction Screening Test-Revised has been translated and verified in the Persian language. Methods: To this purpose, the original screening test was translated to the Persian language and also back translated for matching by two different expert teams. Data was collected through online survey from 1268 participants who were between 18 to 65 years old (M=29.44 and SD=6.90) that 56.1% and 43.9% of them where women and men respectively. Three questionnaires including sexual addiction screening test–revised (SAST-R), hypersexual behavior consequences scale, and Connor-Davidson Resilience Scale as the principal, convergent and divergent tests were administered to the participants. Results: The reliability of the test's internal consistency (Cronbach's alpha = 0.883), Split-Half (Cronbach's alpha = 0.779), and Guttman (lambda coefficients were between 0.773 to 0.883) tests were used. In addition, four methods of content validity (sexual hyperactivity specialist approved), convergent structure validity (P<0.001, R =0.731), the validity of divergent structure (P<0.09, R = -0.132), and factor validity (CFI=0.884, GFI=0.873, RMSEA=0.047) were measured and confirmed the validity of the test. Conclusion: The Persian version of the sexual addiction screening test–revised (SAST-R) seems to be a reliable pre-clinical tool to assess the severity of sexual desire of patients.
