Abstract
- Previous studies among adolescents conceptualize behavioral cognitions [e.g., intentions and perceived behavioral control (PBC)] as stable trait-like factors despite evidence suggesting they vary momentarily. We examined whether intentions and PBC momentarily relate to subsequent sedentary time during non-school periods. Healthy adolescents (N = 15, ages 11-15) reported their intentions and PBC regarding sedentary leisure behaviors via ecological momentary assessment (EMA) up to seven times/day for 14 days. Sedentary time in the two hours following each EMA prompt was measured by ActivPAL accelerometers. When participants reported greater sedentary intentions (within-person [beta] = 1.1, 95% CI 0.2, 2.1, p = 0.0213) and sedentary PBC (within-person [beta] = 1.7, 95% CI 0.6, 2.8, p = 0.0029), they accumulated greater sedentary time. This demonstrates that sedentary intentions and PBC are acutely associated with sedentary time among adolescents. Our findings highlight the potential for implementing just-in-time activity interventions among adolescents during at-risk periods within the day, characterized by deviations from one's usual intentions and PBC levels.<br />Author(s): Shayan Ebrahimian [sup.1] , Jennifer Zink [sup.1] , Chih-Hsiang Yang [sup.2] , Qihan Yu [sup.1] , Kellie Imm [sup.1] , Michele Nicolo [sup.1] , Genevieve F.
