Applying the transtheoretical model to ethnically diverse women at risk for HIV.

The purpose of this study is to compare the reliability and predictability of transtheoretical model (TTM) constructs when applied to minority and White women at risk for HIV. Participants consisted of 332 women, including Blacks, Asians, Hispanics, Native Americans, other non-Whites, and Whites. The results supported the reliability and validity of the TTM variables for minority women as well as for White women. Hierarchical multiple regressions demonstrated that TTM variables were able to predict over and above demographic variables. Structural equation models indicate strong support for a mediational model in which the pros and cons predict condom stage of change and unprotected sex though the mediation of self-efficacy. This study provides strong support for TTM scales applied to minority as well as White women at risk for HIV. The authors discuss how these variables might be incorporated into interventions aimed at increasing condom use in minority women.
