A cross-lagged model of habits, implicit attitudes, autonomous motivation, and physical activity during COVID-19.

Although the relationship between autonomous motivation and impulsive processes has been acknowledged in the context of physical activity, the directionality of this relationship is not clearly understood. The COVID-19 pandemic provides a unique opportunity to investigate such relationships due to the fact that contextual changes brought about by government restrictions (e.g., stay at home orders, indoor gymnasium closures) may have influenced people's physical activity habits and motivation. The purpose of this study was to therefore investigate the bi-directional relationships between physical activity and previously established correlates: autonomous motivation, implicit attitudes, and habit. A sample of university students completed measures that assessed autonomous motivation, implicit attitude, habit and behaviors towards meeting physical activity guidelines each week during the coronavirus period at two time points, two weeks apart in a cross-lagged panel design. Path analysis found a significant reciprocal relationship between habits and autonomous motivation. There were no significant reciprocal relationships between autonomous motivation and implicit attitude, or with any study constructs and behavior. Current findings provide important preliminary formative evidence of associations between autonomous motivation and impulsive behavioral correlates, indicating a bi-directional relationship between autonomous motivation and physical activity habits.
