Summary
Men with gambling disorder (GD) exhibit higher impulsivity across response, choice, and tendency domains compared to healthy controls. Response impulsivity uniquely correlates with gambling disorder severity.
Area of Science:
- Psychology
- Neuroscience
- Behavioral Science
Background:
- Impulsivity is a complex trait.
- Gambling disorder (GD) is linked to impulsivity, but multidomain impulsivity is understudied in GD.
- Theoretical models propose distinct facets of impulsivity.
Purpose of the Study:
- To compare three impulsivity facets (response, choice, tendency) between GD patients and healthy controls (HC).
- To investigate interrelations between impulsivity facets.
- To examine associations between impulsivity facets and GD severity.
Main Methods:
- Study included 97 treatment-seeking men with GD and 32 male HC.
- Diagnosis of GD followed DSM-5 criteria.
- Three facets of impulsivity were assessed.
Main Results:
- Men with GD showed significantly higher levels of response impulsivity, choice impulsivity, and impulsive tendency than HC.
- Interactions between impulsivity facets were observed in both GD and HC groups.
- Only response impulsivity was significantly associated with gambling disorder severity.
Conclusions:
- Multiple domains of impulsivity are critically relevant in gambling disorder.
- Future research should explore targeted interventions for specific impulsivity facets to improve GD outcomes.

Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
