Developmental trajectories of mother-adolescent agreement on maternal autonomy support and their contributions to adolescents' adjustment.

Based on a multi-informant, longitudinal perspective on parent-adolescent relationships, this study examined patterns of convergence and divergence on maternal autonomy support. It had two aims: First, it sought to identify developmental trajectories of maternal autonomy support across adolescence from the perspectives of both mothers and adolescents. A second was to evaluate the longitudinal relation between self-reported and perceived maternal autonomy support by combining informants' trajectories. Data come from two 5-year longitudinal multi-informant studies ( N S1 = 687 mother-child dyads; N S2 = 745 mother-child dyads). Each year, mothers and adolescents completed a questionnaire assessing maternal autonomy support. In both the samples, results of growth mixture modeling showed from mothers' perspective the presence of two distinct trajectories: high (91% of the sample) and moderate and relatively stable (9%) trajectories. From the adolescents' perspective, three trajectories were identified: high and relatively stable (75.7%), high and decreasing (11.8%), and moderate and increasing (12.5%). The normative mother-adolescent convergence pattern was one in which both adolescents and their mother reporting high levels of autonomy support. It was generally associated with more positive indices of adjustment, although academic achievement was highest when adolescents reported comparatively more autonomy support than their mother. The worst mother-adolescent convergence pattern tended to be one in which both reported initially moderate levels of autonomy support that remained relatively stable for mothers and increased for youths. Implications for parenting research and interventions are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
