Delve into the ideal resource for theory and research on parental monitoring and adolescents' disclosure and concealment from parents. This handbook presents ground-breaking research exploring how adolescents respond to parents' attempts to control and manage their activities and feelings. The chapters highlight how adolescents' responses are as important for their mental health and behaviour as parents' attempts to regulate them. Examining responsive, intrusive, and invasive parenting behaviours, the volume addresses modern challenges like monitoring in the digital age and medical decision-making. It covers cutting-edge research on diverse cultures and groups including Latinx, Turkish, Chinese, LGBTQ+, and chronically ill youth. The internationally recognized contributors offer insights from different theoretical perspectives and describe novel methodological approaches, focusing on variations across different developmental stages, contexts, and cultures.
