Abstract
The study addresses some gaps in the current understanding of adolescents' Problematic Social Network Site Use (PSNSU) by exploring the role of parenting as a precursor, and dysregulation and self-esteem as possible mediators. The sample includes 148 parents (15% fathers) and their adolescent offspring (23% male, age ranging from 14 to 18 years old, M = 15.96, SD = 1.36). Parent-reported dysregulation and positive/negative parenting style and adolescent-reported PSNSU and self-esteem were collected. As to positive parenting, simple parallel mediations were fully supported: positive parenting was associated with less dysregulation and higher self-esteem and both conditions independently predicted adolescents' PSNSU. Additionally, a serial mediation model was confirmed, suggesting that positive parenting is associated with less PSNSU by means of the sequential effect of dysregulation on self-esteem. As to negative parenting, results only support one simple mediation: negative parenting predicted PSNSU through dysregulation. Self-esteem was not impacted by negative parenting, interrupting the indirect pathways. The direct effect of negative parenting on PSNSU was significant, suggesting a partial mediation. Findings deepen the current understanding of teens' PSNSU and highlight the importance of targeting parenting when implementing interventions to prevent and treat PSNSU.
