The relationship-oriented information-motivation-behavioral skills model: a multilevel structural equation model among dyads.
Transmission rates of HIV infection have increased steadily among heterosexual adults, however current theoretical models have not been tested statistically at the dyadic level in which risk behaviors occur. The purpose of the current study was to test an Information-Motivation-Behavioral skills (IMB) model of HIV risk behavior (IMB) specifically articulated for heterosexual couples in established relationships using data from both members of 75 dyads. The multilevel relationship-oriented information-motivation-behavioral skills (RELO-IMB) model was evaluated at the individual and dyadic level of analysis to examine partner differences on core variables. Results indicated that not only did the RELO-IMB model provide a good fit to the data when analyzed at the dyadic level, but that the structural relations among the core variables were quite different between the individual- and dyadic-level models. This is the first theoretical model of HIV risk behavior to be analyzed at the dyadic level, and the results suggest ways to effectively design intervention strategies for individuals in intimate relationships.
