Abstract
The Transtheoretical Model of Change (TMC) postulates two sensitive mediating variables, decisional balance and self-efficacy. Four measures of condom use developed with 296 women at high risk for HIV infection or transmission representing these two constructs were cross-validated with 248 heterosexually active college men and women. Confirmatory factor analysis (CFA) procedures were conducted with structural equation modeling (SEM). Factor struc tures for all condom-use measures were replicated using the second independent sample and a different method of analysis, demonstrating the robustness of the scales. Model fit indices were excellent (e.g., decisional balance = .94 and .95; self-efficacy = .97 and .99), suggesting that more standardized measures can be used when assessing attitudes and behaviors toward condom use among heterosexual populations at various risk for HIV or sexually transmitted disease infection.
