Social Ecological Model (SEM) - Integrated Social Work

 


Social Ecological Model (SEM)

The Social Ecological Model (SEM) is a theory-based framework for understanding the multifaceted and interactive effects of personal and environmental factors that determine behaviours, and for identifying behavioural and organizational leverage points and intermediaries for health promotion within organizations.  There are five nested, hierarchical levels of the SEM:  Individual, interpersonal, community, organizational, and policy/enabling environment (Figure 1).   Table 1 provides a brief description of each of the SEM levels.  The most effective approach to public health prevention and control uses a combination of interventions at all levels of the model.
