Abstract
OBJECTIVE: To evaluate whether computer-based prostate cancer screening decision aids enhance decision self-efficacy for African-American men, culturally relevant and reliable measures are needed. However, limited psychometric evidence exists on the health-related decision self-efficacy of African-American men. This study describes the development and psychometric evaluation of the 11-item Informed Prostate Cancer Screening Decision Self-Efficacy Scale among 354 African-American men. METHODS: Exploratory factor analysis was conducted with maximum-likelihood estimation and polychoric correlations followed by Promax and Varimax rotations. RESULTS: Exploratory factor analysis yielded a one-factor, 11-item model of the modified scale with excellent internal consistency reliability at 0.95 and factor loadings ranging from 0.70 to 0.90. Both parallel analysis and a scree plot confirmed the retention of one factor, and the standardized root mean square residual (0.06) indicated that the factor structure explained most of the correlations. CONCLUSIONS: Findings suggest the one-factor, 11-item Informed Prostate Cancer Screening Decision Self-Efficacy Scale has excellent psychometric properties and utility in reliably measuring health-related decision self-efficacy in African-American men. Future research is needed to confirm this factor structure among socio-demographically diverse African Americans.
