RT Article T1 Developmental Trajectories of Justice System-Involved Friendship Proportion: Relevance for Predicting Continued Offending Risk in Emerging Adulthood JF Criminal justice review VO 47 IS 3 SP 334 OP 353 A1 Wojciechowski, Thomas LA English YR 2022 UL https://krimdok.uni-tuebingen.de/Record/1807227219 AB There is limited research which has examined the developmental nature of friendships and their relevance for offending. This study examined heterogeneity in the development of justice system-involved friendship proportionality and its relevance for predicting offending continuity in emerging adulthood. Having a greater proportion of such peers within a friendship collective as individuals exit adolescence may lead to continued risk of offending in adulthood. The Pathways to Desistance data were used in analyses. Group-based trajectory modeling was used to identify developmental patterns of justice system-involved friendship proportionality during adolescence and emerging adulthood. Logistic regression was used to assess the relevance of trajectory group assignment for predicting offending risk in emerging adulthood. Findings indicated that a six-group trajectory model best fit the data. All other trajectory groups in the model indicated a lower risk of offending in emerging adulthood than the High Chronic justice system-involved friendship proportionality group. Sensitivity analyses indicated that separation from criminal peers following adolescence may be a more conservative predictor of offending risk in emerging adulthood.
