Translation and psychometric properties of the sexually transmitted infection prevention scales in females
Abstract
Objective (s): Considering the importance of preventive behaviors of sexually transmitted infections in women as a vulnerable group, for the first time this study aimed to translate and evaluate the validity and reliability of four sexually transmitted infection prevention scales in females. Methods: A standard forward-backward translation method used to develop the Persian version of four sexually transmitted infection prevention scales. Content validity of the scales (knowledge, perceived vulnerability, self-efficacy, and Intention) was assessed through a panel expert. Face validity of scales was established via impact score and a sample of lay people. The reliability of the questionnaire was evaluated by the test-retest method (intraclass correlation coefficient) and internal consistency (calculating the Cronbach’s alpha coefficient). Results: The CVR and CVI for the four-scales ranged from 0.56 to 1.00 and from 0.83 to 1.00 respectively. The impact score of all items was more than 1.5. The Cronbachchr('39')s alpha coefficient and intraclass correlation coefficient was 0.66 – 0.85 and (0.84- 0.97 respectively. Conclusion: The results showed that the Persian version of four sexually transmitted infection prevention scales has proper validity and reliability. It can be used as a useful tool to evaluate knowledge, perceived vulnerability, self-efficacy, and intent to prevent infections about STI in females.
