Abstract

ABSTRACTIntroductionAccording to the self‐medication hypothesis, worriers use substances to cope with their symptoms; however, some published results have challenged this hypothesis. The aim of this study is to show if worry increases the risk of SUD when it is negatively appraised by negative metacognitive beliefs.MethodWe recruited three samples: 68 patients with a severe AUD, 27 patients dependent on eating and 42 control participants. We used the Yale Food Addiction Scale‐2, the Metacognitions Questionnaire‐65, the UPPS‐P Impulsive Behaviour Scale and the Anxiety Thoughts Inventory.ResultsWe confirmed a direct effect of worries and metaworry on alcohol (AUD) and eating addiction (EA), but our multivariate analyses revealed that metacognitive beliefs and metaworry are the most robust predictors of alcohol and eating addiction.DiscussionWe reported substance‐related differences in the relationship between worry and addiction. AUD is related to the metacognitive activity set in motion by worries while EA is associated with a maladaptive form of worry (meta‐worry) where worries are negatively interpreted.
