Introduction
Emergent mental illness during adolescence affects daily functioning,
causing disruption to daily activities, routines, and patterns. Multiple
inter-related personal, social and environmental determinants influence
the onset, nature and subsequent course of those difficulties. Research
suggests a bi-directional relationship exists between mental health and
activity choices. Activity-focused interventions such as occupational
therapy may improve adolescent mental health related outcomes. In this
study, we identify and select which activity-related determinants should
be prioritised in the development of an occupation therapy-based
intervention for adolescents with emerging mental health difficulties
using expert consensus.
