HIV has become a public health concern among persons who use drugs (PWUDs), who are at significantly increased rates of risky sexual behaviors (e.g., unprotected sex and increased numbers of sexual partners) linked to HIV. Aside from abstinence, condom use is one of the only ways to prevent the contraction of HIV through sexual activity. Yet, PWUDs use condoms less than 25% of the time. Condom use self-efficacy (CUSE) is one factor shown to have a positive influence on condom use. However, PWUDs consistently have lower rates of CUSE compared to non-substance users. Gender and racial differences in CUSE are also prevalent. The 15-item Condom Use Self-Efficacy Scale (CUSES; revised from the original 28 item measure) was developed on college student populations to assess an individual’s confidence in their ability to use condoms in different situations. Although studies have found that the CUSES is an appropriate assessment tool to adequately measure CUSE among college students, the CUSES has yet to be validated among samples of PWUDs, and those of different gender and racial groups. When compared to college students, PWUDs may encounter unique barriers that may impact CUSE making the generalizability of one standardized measurement tool for both college student and PWUDs unclear. Thus, the current study examined psychometric properties of the 15-item CUSES among a sample of substance using adults of different gender and racial groups. The current study is a secondary analysis using baseline data collected from the National Institute on Drug Abuse Clinical Trials Network AWARE study. The final sample for the current study consisted of 1,356 substance users. Measures assessing demographics, CUSE and condom use were used for the current study. Correlation analyses found a significant positive relationship between CUSES and condom use for the overall sample, men and women, Black and White men, and Black and White women. Confirmatory factor analysis concluded that the 15-item, four factor structure of the CUSES fit the data for the total sample of adult substance users. Additionally, the 15-item, four factor model fit the data similarly for males and females, and Black and White males. However, a 14-item model was also found to be appropriate for Black males with the removal of item seven due to a low factor loading. The 15-item, four factor model also fit the data similarly for Black and White females, although the model was not a good fit for either group, suggesting the need for future research to find a more appropriate model. Internal consistency reliability estimates ranged from poor (a=0.47) to good (a=0.91) across all groups of interest. However, removal of item seven produced significant improvements in reliability estimates (a=0.65 – 0.91), especially for Black men and women. Taken together, the 15-item CUSES is generally appropriate to use when measuring CUSE among mixed gender and racial samples of adult substance users. However, a 14-item CUSES should also be considered when studying solely Black males and additional research is needed to find a well-fitting model for Black and White females.
