Abstract
The objectives were to i) determine whether a mobile connected activity-tracking device could change physical activity (PA) health behaviour, ii) test whether the theory of planned behaviour could predict participation in physical activity, measured by mobile technology, iii) determine if PA engagement was correlated with mobile communication usage and vehicle journey time. Participants consisted of 41 males and 28 females (N=69), each completing standard TPB measures at baseline. Intervention included a health warning/advice sheet and activity-tracking wearable device. ANOVA results found a significant interaction effect of 37% when wearing device versus not. Findings did not the support the TPB as a predictor of PA engagement in a technology intervention context. Multiple regression results found no relationship between PA participation and mobile communication usage or vehicle journey time. A basis for developing interventions to include mobile connected devices for improved behavioural health is discussed.
