Human Immunodeficiency Virus (HIV) infection continues to disproportionately affect African-American communities. While African-Americans represent only 18.5% of Harris County population, they account for 54% of the HIV cases and continue to outnumber whites in new HIV cases. The lack of consistent and correct condom use is the leading mode of transmission for HIV in African-Americans. The first paper focuses on the developing of the condom use knowledge scale and condom use. Results suggest that the condom use knowledge scale was easy to use, acceptable, reliable and valid. The second paper investigate the association between condom use knowledge and self-reported condom use while controlling for age, educational level, marital status, and religious affiliation. The results indicate no significant association identified between condom use knowledge and condom use (p=0.27). However, condom use was significantly associated with level of education (p=0.04) and age group (p=0.02). The final paper assess the association between the Theory of Planned Behavior (TPB) constructs (attitude towards condom use, subjective norm, perceived behavior control, perceived behavioral self-efficacy and behavioral intention) and reported condom use with steady and casual partners. The results indicate statistically significant associations between subjective norms and participants’ condom use (p=0.01) with their steady partner. The findings indicated no TBP constructs were significantly associated with casual partner condom use among the participants. The results for casual partner condom use indicated statistically significant association among married women and their condom use (p=0.04).
