The Condom Attitude Scale (W. P. Sacco, B. Levine, D. L. Reed, & K. Thompson, 1991) was modified for use with adolescents. In Study 1, a modified 35-item version, pilot tested with 195 African American adolescents, achieved a Cronbach's alpha of .88. In Study 2, convergent validity was assessed with a sample of 312 African American adolescents. Psychometric properties were evaluated with item analysis, factor analysis, and reliability estimation. The scale was refined to 23 items with a full scale Cronbach's alpha of .80. In Study 3, temporal stability was assessed with 88 African American adolescents. In Study 4, a cross-validation sample of predominantly White adolescents (N = 2) assessed whether the measure's psychometric properties and factor structure replicated in a more heterogeneous adolescent sample.
