IN2SHAPE: A Study of Physical Activity and Depressive Symptoms in Adolescence

Australian National University26 enrolled

Overview

The purpose of this study is to determine whether physical activity prevents development of depressive symptoms in adolescents.

The primary objective of the project is to establish whether increasing physical activity can promote mental well-being in adolescents who are already displaying some depressive symptoms. A further objective is to evaluate the feasibility of a novel self-motivated physical activity intervention, which has been designed for this project. The final objective of this project is to investigate alternative intervention delivery modes, for an adolescent sample with subclinical depressive symptomatology, i.e., presenting with some depression symptoms but not at a level where major depressive disorder would be diagnosed. We aim to compare the effect of a completely mediated delivery approach for physical activity (i.e., no researcher contact) and a mediated intervention with face-to-face contact and fortnightly check-in telephone calls.
