Background and aims: The importance of personality characteristics in the diagnostics and treatment of gambling disorder (GD) and alcohol use disorder (AUD) is often highlighted in scientific literature. This study aimed to test predictions about the associations of temperament and character in chronic AUD patients with comorbid GD symptoms and without them.
Methods: Chronic AUD patients enrolled from an inpatient clinic were divided in two groups based on cluster analysis, AUD patients with (AUD+GD groups: N = 30) and without (AUD groups: N = 68) GD symptoms. Severity of GD symptoms and personality dimensions (Cloninger’s Temperament and Character Inventory Revised, TCI-R) were assessed. Associations of tested variables were analysed with analysis of covariance, one-sample and independent sample t-tests.
Results: GD symptoms proved to be a clustering factor in terms of personality, where AUD+GD groups expressed a more maladaptive personality profile. Compared to Hungarian normative TCI-R scores, both patient groups showed elevated levels of Harm Avoidance and Novelty Seeking with lower scores of Self-directedness, while the AUD+GD group scored lower on Persistence and Cooperation as well. The AUD+GD group reported significantly higher levels of Harm Avoidance, with lower scores of Reward Dependence compared to the AUD group.
Discussion: Comorbid GD symptom severity is an important factor in chronic AUD, where AUD patients with comorbid GD symptoms exhibited more maladaptive personality constellation than singular AUD patients. These emphasize the need of special attention for comorbid GD symptoms in AUD, since treatment recommendations and prognosis for them may also differ. Link to the article
