摘要
Introduction: Excessive recreational screen time (i.e., screen use for entertainment) is a global public health issue associated with adverse mental and physical health outcomes. Considering the growing popularity of screen-based recreation in adolescents, there is a need to identify effective strategies for reducing screen time among adolescents. The aim of this paper is to report the rationale and study protocol for the 'Switch-off 4 Healthy Minds' (S4HM) study, an intervention designed to reduce recreational screen time among adolescents. Methods: The S4HM intervention will be evaluated using a cluster randomized controlled trial in eight secondary schools (N = 322 students) in New South Wales, Australia. The 6-month multicomponent intervention will encourage adolescents to manage their recreational screen time using a range of evidence-based strategies. The intervention is grounded in Self-Determination Theory (SDT) and includes the following components: an interactive seminar for students, eHealth messaging, behavioral contract and parental newsletters. All outcomes will be assessed at baseline and at 6-months (i.e., immediate post-test). The primary outcome is recreational screen time measured by the Adolescent Sedentary Activity Questionnaire (ASAQ). Secondary outcomes include: self-reported psychological well-being, psychological distress, global physical self-concept, resilience, pathological video gaming and aggression, and objectively measured physical activity (accelerometry) and body mass index (BMI). Hypothesized mediators of behavior change will also be explored. Discussion: The S4HM study will involve the evaluation of an innovative, theory-driven, multicomponent intervention that targets students and their parents and is designed to reduce recreational screen time in adolescents. The intervention has been designed for scalability and dissemination across Australian secondary schools. (C) 2014 Elsevier Inc. All rights reserved.
