Daily Associations Between Positive Emotion and Obesity-Related Behaviors and Their Interconnections Within Adolescent–Caregiver Dyads

Abstract Background Greater overall positive emotion has been linked with increased physical activity and overeating. High approach positive emotions (HAPEs), a subtype of positive emotion, are theorized to facilitate this goal-driven behavior. However, the day-to-day associations of HAPE and physical activity and overeating, including both at the individual level and within caregiver–adolescent dyads, remain unknown. Purpose We examined the independent and dyadic associations between HAPE (positive emotions that occur pregoal and motivate individuals toward approaching/acting upon that motive) and obesity-related behaviors, including physical activity and overeating, in adolescents and their primary caregivers. Methods Adolescents (N = 47) aged 11–17 and their caregivers completed demographic questions and a 7-day diary at the end of each day about daily emotion, and physical activity and overeating behaviors. Results For adolescents and their caregivers, increased day-to-day fluctuations in HAPE and greater average HAPE was associated with increases in their own daily physical activity levels. Greater average caregiver HAPE was also associated with increased overeating in caregivers. When examining interdependency within dyads, greater average caregiver HAPE was associated with greater adolescent overeating behavior. Conclusions There is evidence that HAPE is related to obesity-related health promoting behaviors and health risk behaviors in adolescence and adulthood. Future studies should further explore mechanisms underlying these associations, including within the family system. In adolescents and their caregivers, positive emotion was related to both physical activity and overeating. Caregivers’ positive emotion was related to adolescents’ overeating
