A Longitudinal Study of Physical Activity and Personality in the Wellbeing of Older Adults

Objective: This study examines the interactions of physical activity and personality traits in the subjective wellbeing (SWB) of older adults. Methods: 520 Scottish participants (262 male; 258 female) completed self-reported surveys measuring their level of physical activity, personality, and SWB in 2011–2013 (mean age = 76.23 ± .68) and in 2014–2016 (mean age = 79.31 ± .62). Results: While all of the Big Five personality traits predicted SWB across the 3-year period in the expected direction, neither physical activity nor its joint effect with any of the personality traits was a significant predictor of subsequent SWB. Discussion: Further research on older adults with higher variation in age, exercise level, and cultural background is needed to disentangle how physical activity and personality influence SWB.
