There are 4 major groups or levels of influences that can affect risks for violence.
-   Individual factors: the biological, genetic, or personal factors that place one at risk
-   Relationship factors: those from family, significant others, or peers that influence attitudes or behaviours
-   Community factors: include attitudes, beliefs in organizations, or communities that support or tolerate violence or inequality
-   Societal factors: include cultural norms, societal values, or policies allowing violence or condoning inequality, such as income distribution or social exclusion of individuals or groups. (page 489)
