Introduction: Although physical activity helps to improve functioning and reduce the symptoms of mental illness, physical inactivity remains common in the mental illness population. This study aims to explore the associations between theoretical constructs in relation to physical activity behavior based on psychological theories to examine reasons for physical inactivity in psychosis population.
Methods: One hundred and eighty one Chinese outpatients diagnosed with psychotic disorders were recruited for this cross-sectional study. Sociodemographic data and responses to questionnaires measuring self-efficacy, decisional balance, processes of change, and stages of change on physical activity habit were collected.
Results: Ninety three subjects (51.4%) had the intention to engage in regular physical activity within the next six months. Significant differences were found in self-efficacy, pros of decisional balance and processes of change across the stages of change. Moreover, overall classification accuracy was 60.8% across the stages of change.
Conclusions: This study supports self-efficacy, pros of decisional balance and processes of change as useful factors in understanding physical activity behavior among patients with psychosis. Future promotions of regular physical activity can focus on improving self-efficacy, emphasizing on the benefits of regular physical activity and facilitating cognitive and behavior strategies from processes of change.
