Measuring the condom use self-efficacy of deployed, enlisted male U.S. Naval personnel

This article summarizes the development and psychometric analysis of a condom use self-efficacy measure for deployed, enlisted male U.S. Naval personnel. Sample ethnic subgroups included European American, Latino/Hispanic, African American, Asian American, Native American, Pacific Islander, and Biracial/Multiracial. Excellent reliability statistics were obtained for the full sample (alpha = .93, N = 2,722) and various ethnic subgroups (alpha = .93 to .95, n = 44 to 1,383). Correlations between self-efficacy scores and measures of condom use were similar in magnitude to effect sizes reported in research involving civilian populations (r = .18 to .34). Significant differences in self-efficacy scores for groups of condom users (e.g., consistent and nonconsistent users) for the full sample of men and ethnic subgroups provided further support for construct validity (p < .05). Study findings support the reliability and validity of the condom self-efficacy measure in this population and indicate its usefulness and the need for investigating its psychometric properties in other populations.
