Ecological Momentary Assessment (EMA) is a real-time data capture strategy where participants are repeatedly assessed in the context of everyday life. • Allows for the analysis of processes over time • Reduces recall biases • Improves ecological validity of findings @jaclynpmaher (Stone & Shiffman, 1994; Stone, Shiffman, & Hufford, 2008)

Multilevel linear regression was conducted to test a dual process model of older adults momentary sedentary behavior. @jaclynpmaher
Both conscious and non-conscious motivational processes predict older adults’ momentary sedentary behavior. @jaclynpmaher
Study findings add to accumulating evidence that health behaviors are regulated by both conscious and non-conscious motivational processes. Interventions should integrate content aiming to: • Enhance momentary intention formation and efficacy beliefs • Disrupt habitual sedentary behavior @jaclynpmaher
Considerations for future research investigating dual-processes regulating sedentary behavior in older adults: • Additional conscious and non-conscious processes • Measurement of conscious and non-conscious processes • Event-contingent vs signal-contingent EMA protocols @jaclynpmaher
This work emphasizes the importance of conceptualizing sedentary behavior motivation through a dual-process lens. Thank you! Funding for this study was provided by the University of Southern California’s Provost Postdoctoral Scholar Research Grant @jaclynpmaher
