RESUMO
During adolescence, a secure parent-adolescent relationship promotes youths' adjustment and psychological well-being. In this scenario, several studies have demonstrated the effectiveness of the CONNECT program, a 10-session, attachment-based parenting intervention that helps parents understand and reframe their parent-adolescent interactions, reducing adolescents' insecure attachment and behavioral problems. Furthermore, recent years have witnessed a significant increase in the implementation of effective online versions of psychological interventions, emphasizing the opportunity for more agile and easier dissemination of evidence-based protocols. Therefore, this study aims to identify changes in adolescents' attachment insecurity, behavioral problems, and parent-child affect regulation strategies, providing preliminary findings on an online, 10-session, attachment-based parenting intervention (eCONNECT). A total of 24 parents (20 mothers, 4 fathers; Mage = 49.33, SD = 5.32) of adolescents (Mage = 13.83 years, SD = 1.76, 45.8% girls) were assessed on their adolescents' attachment insecurity (avoidance and anxiety) and behavioral problems (externalizing and internalizing), and on their affect regulation strategies in the parent-child interaction (adaptive reflection, suppression, and affect dysregulation) at three time points: before intervention (t0), after intervention (t1), and at a 2-month follow-up (t2). Mixed-effects regression models highlighted a reduction in adolescents' internalizing problems (d = 0.11), externalizing problems (d = 0.29), and attachment avoidance (d = 0.26) after the intervention. Moreover, the reduction in externalizing problems and attachment avoidance remained stable at follow-up. Additionally, our findings highlighted a reduction in parent-child affect dysregulation. Results add preliminary evidence on the implementation suitability of an online attachment-based parenting intervention to change at-risk adolescents' developmental trajectories by reducing attachment insecurity, behavioral problems, and parent-child affect regulation.
