The dynamics of delinquent peers and delinquent behavior

This analysis examines the dynamic reciprocal relationship between delinquent peer associations and delinquent behavior It tests the hypothesis, derived from learning and interactional theories, that delinquent peers and delinquent behavior are reciprocally related-delinquent peer associations foster future delinquency, and delinquency increases the likelihood of associating with delinquent peers. It also tests the competing hypothesis, derived from control theories, that delinquent peers do not cause delinquency, but instead the relationship is (1) spurious due to individual criminal propensity, (2) a result of the effects of delinquent behavior on future associations with delinquent peers, or (3) an artifact of problems of measuring delinquent peers. To test these propositions, we use data from the National Youth Survey and estimate a cross-lagged panel model that corrects for measurement error in indicators of delinquent peers and delinquent behavior. The model specifies a covariance structure model fbr ordinal measures. Parameters are estimated by (1) estimating a threshold model relating ordinal measures to continuous latent variables; (2) estimating a matrix of polychoric correlations relating observed variables, and (3) using an asymptotic distribution-free estimator to estimate structural parameters. The results suggest that delinquent peer associations and delinquent behavior are reciprocally related, but the effect of delinquency on peer associations is larger than that of peer associations on delinquency.
