We examined how parenting is directly and indirectly associated with adolescent delinquency. We derived four possible mechanisms from major criminological theories and examined their relative contribution to explaining the relationship between parenting and delinquency: self-control theory (that is, self-control), differential association theory (that is, delinquent attitudes and peer delinquency), and routine activity theory (that is, time spent in criminogenic settings). In addition, we examined how changes in different aspects of parenting during adolescence were directly and indirectly related to changes in delinquency. Results of multilevel structural equation modeling on two waves of panel data on 603 adolescents indicated that parenting was indirectly related to delinquency through self-control, delinquent attitudes, peer delinquency, and time spent in criminogenic settings. However, only when examined together these variables, derived from major criminological theories, almost fully mediate the effects of parenting. Furthermore, changes in parenting during adolescence were indirectly related to changes in delinquency through changes in delinquent attitudes and in peer delinquency.
