A model is presented that explains the contribution of parents and peers to adolescent delinquent behavior. It is hypothesized that during adolescence a failure in Parent Monitoring and deficits in Social Skills increase the likelihood that a youngster associates with Deviant Peers. Poor Parent Monitoring Deviant Peers, and low levels of Academic Skills are hypothesized to contribute directly to an adolescent's engagement in delinquent behavior, The present model was tested on a sample of 136 seventh and tenth grade male adolescents by using the structural modeling approach in the LISREL IV analysis program (Jöreskog&Sörbom, 1978). The major revision of the model was that the correlation between Academic Skills and Parent Monitoring was set to zero. A chi square goodness‐of‐fit test for the revised model showed adequate agreement between the hypothesized model and the observed covariance structure of the data. It was suggested that a number of requirements be completed before accepting the above model: (1) replication of this model on a new set of data, (2) longitudinal analyses showing the hypothesized relations through time, and (3) experimental testing by manipulation of one or more independent variables, as is possible in clinical intervention st
