In a post about public health and epistemologies of ignorance, I argued that public health interventions have focused solely on the individual rather than looking at other factors impacting health. Moving forward, we need to develop multi-level models of health behavior, so here are a few examples of a multi-level analysis and multi-level models related to HIV prevention and AIDS care. Kaufman et al (2014) present a multi-level analysis of factors impacting HIV-related behavior and behavior change and review a few recent models for looking at HIV-related health behavior from multiple levels. The transtheoretical and health belief models and the theories of reasoned action and planed behavior have been used repeatedly in public health literature about HIV-related health behaviors, but all of these models and theories focus on the individual rather than looking at the individual as part of a larger system.
Kaufman et al (2014) looked at four multi-level models that expand on the individual models of health behavior to look at a more holistic picture:
- The Multiple Domain Model: Zimmerman, R. S., Noar, S. M., Feist-Price, S., Dekthar, O., Cupp, P. K., Anderman, E., & Lock, S. (2007). Longitudinal test of a multiple domain model of adolescent condom use. Journal of Sex Research, 44(4), 380-394.
- The Network-Individual-Resource Model: Johnson, B. T., Redding, C. A., DiClemente, R. J., Mustanski, B. S., Dodge, B., Sheeran, P., … & Carey, M. P. (2010). A network-individual-resource model for HIV prevention. AIDS and Behavior, 14(2), 204-221.
- The Dynamic Social Systems Model: Latkin, C., Weeks, M. R., Glasman, L., Galletly, C., & Albarracin, D. (2010). A dynamic social systems model for considering structural factors in HIV prevention and detection. AIDS and Behavior, 14(2), 222-238.
- The Transmission Reduction Intervention Project: Friedman, S. R., Downing, M. J., Smyrnov, P., Nikolopoulos, G., Schneider, J. A., Livak, B., … & Psichogiou, M. (2014). Socially-integrated transdisciplinary HIV prevention. AIDS and Behavior, 18(10), 1821-1834.
These are just a few examples of models that look at factors on multiple levels, specifically for HIV. More work should be done to expand and perfect these models, though the move towards multi-level models is certainly a move in the right direction. We should attempt to use a social-ecological framework with thinking about other public health interventions as well.
