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. [ABSTRACT FROM AUTHOR]

Background and Aims: Pathological buying (PB) is a behavioral addiction that presents comorbidity with several psychiatric disorders. Despite the increase in the prevalence estimates of PB, relatively few PB instruments have been developed. Our aim was to assess the psychometric properties of the Spanish version of the pathological buying screener (PBS) and to explore the associations between PB, psychopathology, and personality traits., Methods: A total of 511 participants, including gambling disorder (GD) and eating disorder (ED) patients diagnosed according to DSM-5 criteria, as well as healthy controls (HCs), took part in the study., Results: Higher PB prevalence was obtained in ED patients than in the other two study groups (ED 12.5% vs. 1.3% HC and 2.7% GD). Confirmatory factor analysis (CFA) verified the 13-item structure of the PBS, and indexes of convergent and discriminant capacity were estimated. CFA confirmed the structure in two factors (excessive buying behavior and loss of control) with excellent internal consistency (α = .92 and .86, respectively). Good convergent capacity was obtained with external psychopathology and personality measures (positive correlations with novelty seeking and negative associations with self-directedness and harm avoidance were found). Good discriminative capacity to differentiate between the study groups was obtained., Discussion and Conclusions: This study provides support for the reliability and validity of the Spanish adaptation of the PBS. Female sex, higher impulsivity, and higher psychopathology were associated with PB.
