Description
Summary: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.
