Translation and validation of the condom self-efficacy scale with Thai adolescents and young adults

Purpose: To translate the 14-item Condom Self-Efficacy Scale (CSES) into Thai and to validate the Thai version of the Condom Self-efficacy Scale (CSES-T) among Thai adolescents and young adults. Methods: The CSES was translated using a back-translation technique and validated with a cluster-based sample of 425 participants aged 18 to 22 years from eight randomly selected private vocational schools in Bangkok. Participants completed anonymous self-administered scales. Principal component analysis with varimax rotation was conducted to identify latent factors. Results: Factor analysis indicated three factors: communication, correct use, and consistent use. Items loading on the original CSES also loaded on the same factors of the CSES-T except one item. The Cronbach's alpha coefficients were .85 for the total scale, .70 for consistent use, .79 for correct use, and .80 for communication. Conclusions: Based on psychometric properties, the CSES-T is a valid and reliable tool. It is culturally appropriate for Thai young adults. Thai researchers and health care providers can use the CSES-T to assess adolescents' and young adults' self-efficacy to use condoms as well as to further develop and evaluate interventions to increase condom use.
