Which factor mediates the negative effects of low income contexts and is associated with lower levels of delinquency over time?

A) peer relationships
B) involvement in school activities
C) high profile community involvement
D) close extended family

Involvement in school activities has been found to be a protective factor against delinquency in low-income contexts. It provides a sense of belonging and motivation to succeed, as well as positive relationships with peers and adults outside of the home environment. While the other factors may also have some protective effects, involvement in school activities has been consistently linked to lower levels of delinquency over time in research studies.
