The soulless cycle: Social physique anxiety as a mediator of the relation between body mass index and exercise frequency

A psychosocial investigation of exercise preferences in real and virtual environments

Three studies explored exercise preferences in real-world and virtual environments, and their relationship with social physique anxiety (SPA), social comparison, and self-presentational efficacy (SPE). In Study 1 (N = 230), real-world exercise preferences were explored. Study 2 (N = 228) measured preferences for real-world and virtual reality (VR) exercise, and Study 3 (N = 249) investigated preferences for avatar embodiment and virtual companions within VR. Results revealed that participants who preferred home-based exercise had lower exercise behaviour, more negative fitness-related social comparisons, or lower SPE expectancy and outcome value (Study 1). Individuals with lower exercise behaviour, more negative fitness-related social comparisons, lower SPE expectancy, or higher SPA were also more likely to choose VR than real-world exercise (Study 2). In a VR exercise setting, participants with higher SPA and more negative social comparisons also preferred to embody a non-human and fantasy avatar more than a realistic avatar. A heightened threat of negative social comparison when imagining exercise with a physically superior virtual companion resulted in the strongest preference to embody a fantasy avatar (Study 3). The results suggest that individuals who place high importance on self-presentation and have low belief in their capacity to project an image of competence to others, are more likely to prefer exercise contexts that minimise physique- and fitness-related evaluation. Moreover, VR may afford a less psychosocially threatening context for individuals who feel self-conscious or comparatively inferior to others during exercise.

Theory to treatment to theory: Evolving a community-based obesity intervention

Within weight-loss treatments, a better understanding of psychosocial correlates of exercise and controlled eating is required to improve lagging outcomes. Within this two-phase study, women with obesity participating in community-based treatments with educational (Phase 1 n = 57, Phase 2 n = 44) and behavioral (Phase 1 n = 80, Phase 2 n = 53) formats were contrasted on psychosocial variables over 3 and 6 months and their interrelations based on the mood-behavior-model and coaction theory. Phase 1 findings informed curricular extensions in Phase 2. In Phase 1, there were significant overall improvements in total mood disturbance, self-regulation of exercise, self-regulation of eating, and weight, which were more pronounced in the behavioral vs. educational format group (-3.5 % vs. -1.4 % weight loss, respectively). Mediation analyses indicated that change in self-regulation of exercise mediated the prediction of change in self-regulation of eating by mood change. Phase 2 findings were similar; however, effect sizes were greater (-6.2 % vs. -2.9 % weight loss, respectively). Within both phases, increased self-regulation of eating significantly predicted weight reduction. Paths from changes in mood→self-regulation of exercise→self-regulation of eating suggested future program attention focus on treatment-associated mood change reinforcing self-regulation, and self-regulation generalizing from an exercise to eating context. Methods of progressing treatment curricula via theory-testing were suggested.
