This study compared the mediated effects of two web-based physical activity interventions: I Move and Active Plus.
Also, the basic psychological need supporting capabilities of these interventions were compared.
I Move is based on SDT and MI; Active Plus is based on traditional health behavioral theories.
The effects of both interventions were equally mediated by perceived competence but not by autonomous motivation.
I Move was found to be more effective in supporting participants’ basic psychological needs.
