Utilizing the social ecological model (SEM) as a framework, this model recognizes the relationships that exist between an individual and his or her environment within and across various systems. The levels within the SEM include: (a) individual, (b) interpersonal (social networks), (c) community (formal and informal social networks), (d) societal (social institutions), and (e) political (public policy). The model addresses the complexities and interdependences between the socioeconomic, cultural, political, environmental, organizational, psychological, and biological determinants of behavior (Stokols, 1996). The application of the social ecological model identifies various differential constraints and opportunities for accessing social, financial, and community resources when situated within each of the social systems.
