Implications
This research has important theoretical and practical implications. First, we showed that individuals’ AAMs can shape their health and well-being independently of their actual physical activity. Although previous research provided suggestive evidence that AAMs may influence health [Second, this study adds to an emerging body of research suggesting that technology design typically overlooks effects on and of health-related mindsets [Third, we provide evidence for a novel meta-mindset intervention that empowers participants to deliberately adopt more positive mindsets and use them to improve health and well-being. Our findings increase the applied utility of mindset research as meta-mindset interventions are nondeceptive and ethical outside the research context. Moreover, meta-mindset interventions have the potential to be mindfully embedded in a wide range of health promotion programs––including technology applications, public health campaigns, and workplace health programs––thereby providing a cost-effective and scalable way to enhance population health.
