Underlying Mechanism of the Comorbid Presence of Buying Disorder with Gambling Disorder: A Pathways Analysis.

Buying disorder (BD) and gambling disorder (GD) are behavioral addictions that are increasingly being researched and treated by mental health professionals. This study analyzes the underlying mechanisms of the comorbidity between both conditions in a sample of treatment-seeking patients. The sample included n = 127 patients recruited from a specialized unit in addictive behaviors at a public university hospital who presented BD symptoms with and without GD. Structural equation models analyzed the mediational mechanisms that explained the presence of the comorbid condition BD + GD. Personality variables indirectly influence the concurrence of GD and BD, and the relationship patterns were modulated by the age of onset of these two conditions. A direct relationship between being male and an increase in the risk of GD + BD comorbidity was also found. Sex and the amount of disorder-related debts also were directly associated with psychopathology. These results provide evidence on the pathways of concurrent BD + GD, which could contribute to the development of evidence-based preventive and therapeutic interventions.
