An example of an individual level risk factor in the Socio-Ecological Model is:

In the context of the Socio-Ecological Model, individual-level risk factors refer to personal attributes that may influence a person's likelihood of engaging in harmful behaviors, such as substance abuse. Genetic predisposition to addiction is a prime example of an individual-level risk factor because it originates within the individual. This genetic background can significantly impact a person's vulnerability to developing addictive behaviors, setting them apart from others who may not have the same predisposition.

While other options touch upon important aspects of social and environmental influences, they do not fit within the definition of an individual-level risk factor as neatly as genetic predisposition. Access to community support groups and stable family relationships are more aligned with community or social-level factors, as they involve external environments and relationships. Positive self-control could be an individual factor, but it is generally considered a protective factor rather than a risk factor in this context, hence making genetic predisposition to addiction the most accurate choice for an individual-level risk factor.
