An adolescent and young adult condom self-efficacy scale.

The purpose of this study was to initially test the psychometric properties of an adolescent and young adult condom self-efficacy scale. The sample consisted of 209 participants (13 to 26 years old) who voluntarily completed a 19-item scale. The items were developed based on a review of the literature and a review by experts in adolescents' and young adults' condom use. Item analysis was conducted and five items were deleted. Principal axis factor analysis with varimax rotation yielded three factors: communication abilities related to condom use, consistent condom use abilities, and correct condom use abilities. The three factors accounted for 42% of the variance. The alpha coefficient was .85 for the total scale. The scale could be used to assess perceived condom self-efficacy and to evaluate effectiveness of strategies to increase perceived condom self-efficacy among adolescents and young adults.
