Developmental Trajectories of Maternal and Paternal Attachment and Delinquency in Adolescence

The present study sought to address two research questions: (1) Are there distinct trajectories of maternal and paternal attachment among adolescents? And if so, (2) How do these trajectories of maternal and paternal attachment relate to delinquent trajectories over the ages of 12 to 16? Using a subsample (n = 383) of the longitudinal Gang Resistance Education and Training (GREAT) data, the results from semi-parametric group-based modeling (SPGM) suggested five groups of maternal attachment, where one trajectory exhibited little to no maternal attachment; another group appeared to have an initially low rate of maternal attachment but increased rather noticeably over time; a third trajectory demonstrated high initial levels of maternal attachment but a general decline over time; and the last two groups exhibited high and rather stable rates of maternal attachment, although one of these groups showed evidence of a decline. Comparatively, the same number of trajectory groups was estimated for paternal attachment, with relatively similar patterns over time as for the maternal attachment trajectories, with the exception of one trajectory that appeared to decline initially before demonstrating a substantial increase. Finally, the results from the joint trajectory analysis indicated that as maternal and paternal attachment increased the likelihood for delinquency decreased. Implications for future research and policy are also discussed.
