Reliability and validity of a Self-Efficacy Scale for AIDS Prevention among Turkish university students.

Abstract

This study design determined the internal consistency, validity and factorial structure of the Turkish Self-Efficacy scale for AIDS (T-SEA-27). The 27 items scale firstly was translated into Turkish using back-translation method and the cultural equivalence was provided by expert views. Secondly, the psychometric properties of the scale were evaluated on 507 university students. The test-retest reliability of the intraclass correlations was satisfactory in a subsample of 60 students tested after a 2-week interval. Psychometric analysis supported the reliability and validity of the T-SEA-27 scale and four subscales: refusing sexual intercourse (a= .97), questioning potential partners (a= .90), condom use (a= .74) and family related (a= .95). The self-efficacy score was significantly higher for those studying in health sciences, those who were not sexually active and the female students. Our outcomes showed that T-SEA-27 is a valid instrument in evaluating self-efficacy for HIV/AIDS in Turkish young people.
