Show moreResearch suggests that individuals with eating disorders use more maladaptive emotion regulation strategies in response to emotional distress. However, these studies do not consider that the efficacy of emotion regulation strategies vary across situations. Recent evidence suggests that healthy emotion regulation is characterized by an ability to flexibly choose between emotion regulation strategies across changing contexts. Despite evidence supporting this conceptualization of healthy emotion regulation, no research has investigated it in relation to eating pathology. This study examined whether eating pathology and difficulties in emotion regulation were associated with emotion regulation choice patterns and flexibility. Female college students (N = 50) completed self-report questionnaires and a laboratory-based emotion regulation choice task to assess emotion regulation flexibility. Generalized estimating equations indicated that individuals with higher levels of eating pathology displayed similar emotion regulation choice patterns and flexibility as those with low levels of eating pathology. Individuals who displayed specific types of emotion regulation difficulties (i.e., emotional clarity, emotional awareness and impulse control difficulties) displayed different emotion regulation choice patterns and flexibility compared to individuals without such difficulties. These results suggest that specific difficulties in emotion regulation have a greater influence on emotion regulation choice patterns and flexibility than eating pathology.

Show moreIndividuals with bulimia nervosa spectrum disorders often compulsively engage in binge eating and purging, despite life threatening consequences. Little is known about factors that contribute to compulsivity in these conditions. The purpose of this study was to investigate whether stress and habitual control over bulimic behaviors play a role in maintaining symptoms in these disorders, using ecological momentary assessment. Women with bulimia nervosa spectrum disorders (N = 81) completed self-report baseline questionnaires and a 14-day EMA protocol which involved daily assessments of stress, negative affect, bulimic behaviors, and contextual antecedents to bulimic behaviors. The results indicated that baseline habitual control over binge eating and purging were not associated with global eating pathology or eating disorder-related clinical impairment. However, exploratory analyses revealed that habitual control over binge eating and purging were associated with more frequent engagement in these behaviors during the previous four weeks. Neither stress appraisal nor stressor frequency were associated with habitual control over bulimic behavior during the EMA period. In terms of affect trajectories surrounding bulimic behaviors, negative affect increased in the hours leading up to these behaviors, decreased in the hours following these behaviors, and was higher immediately after these behaviors compared to before. Habitual control over binge eating and purging did not moderate temporal relations between negative affect and bulimic behaviors during the EMA period. Overall, the findings suggest that habit may play a role in maintaining binge eating and purging.
