Popis: | Introduction: Although anxiety and impulsivity are intuitively thought to be inversely correlated, increased impulsivity has been associated both with generalized anxiety disorder (GAD) diagnosis and GAD symptoms in non-clinical samples. The emotional dysregulation model of GAD posits that patients experience more frequent and intense negative emotions while having poor regulatory control over emotional states and greater negative reactivity to their emotions. We hypothesized that poor regulatory control in the presence of negative emotions might explain the increased impulsivity found in GAD patients. In this study, we examined if negative affect mediates the relationship between GAD and impulsivity. Methods: Thirty-four GAD patients and 35 healthy controls were included, and evaluated with measurements of impulsivity, negative and positive emotions, the severity of worrying and GAD symptoms, depression, and 5-factor personality traits. Results: Global impulsivity scores and the attentional facet of impulsivity were higher in the patient group when compared to the controls. Negative affect was correlated with global impulsivity in the patient group only and explained impulsivity in our regression model while worrying and depressive symptoms did not. An indirect relationship was found between diagnosis and impulsivity through negative affect. Conclusion: Our study showed that the cardinal symptom of GAD – worrying – was not independently related to impulsivity in our sample. Increased impulsivity in GAD seems to be mediated by the increased presence of negative emotions, as it is common in mood and impulse-control disorders, indicating an unspecific shared vulnerability factor to psychopathology. |
