On the pitfalls of conceptualizing excessive physical exercise as an addictive disorder: Commentary on Dinardi et al. (2021) Brevers, Damien Perales López, José César Physical exercise Self-determination theory Addiction-based approach Process-based approach Debate This commentary challenges some of the proposals made in the opinion paper entitled “The expanded interactional model of exercise addiction” by Dinardi, Egorov, and Szabo (2021). We first question the usefulness of the (expanded) interactional model of exercise addiction to determine the psychological processes underlying distress and functional impairment in excessive physical exercise. We then consider the authors’ use of the Self-Determination Theory to model exercise addiction, which risks the misclassification of strenuous, but adaptive, patterns of physical exercise as exercise addiction. We finally address broader concerns regarding the idea that maladaptive exercising could be conceptualized as an addictive disorder. 2022-09-06T08:31:26Z 2022-09-06T08:31:26Z 2022-03-01 journal article Brevers, D...
