Exploring the connection between gambling disorder and criminal behavior in male violent offenders
What drives someone to commit crimes? While we often point to drugs, alcohol, or socioeconomic factors as primary motivators, there's another powerful addiction lurking in the shadows of criminal behavior: gambling disorder. Imagine a violent offender serving time in a maximum-security prison—not the typical image we associate with problematic gambling. Yet, groundbreaking research reveals that gambling disorder represents a critical, though often overlooked, factor in understanding criminal behavior, particularly among incarcerated populations.
Recent scientific investigations have uncovered that an astonishing one in three prisoners struggles with significant gambling problems, a rate dramatically higher than the 0.7-6.5% found in the general adult population2 .
The connection between gambling and crime isn't merely theoretical. This article explores a landmark study that examined this connection in detail, focusing on young male violent offenders in the Swedish prison system. The research not only reveals startling prevalence rates but also uncovers the complex web of psychiatric and substance-related comorbidities that complicate both treatment and rehabilitation.
The relationship between gambling and criminal behavior operates as a vicious, self-reinforcing cycle with multiple pathways:
Problem Behavior Theory provides a useful lens through which to view this connection. According to this theory, behavior results from three interacting systems:
This framework suggests a "problem behavior syndrome" where involvement in one problem behavior (like gambling) frequently co-occurs with involvement in others (like criminal activity)2 .
Approximately 65% of severe problem gamblers in offender populations report that their criminal behavior directly resulted from their gambling activities and accumulated debts8 .
To better understand the gambling-crime connection, researchers conducted a comprehensive investigation within the Swedish prison system3 . The study focused on:
Aged 18-25 serving sentences for violent crimes, including hands-on sexual offenses
From nine different prisons ranging from high to low security
Using structured clinical interviews for DSM-IV disorders
Including intellectual functioning, autism spectrum disorders, neurodevelopmental conditions, criminal history, and educational background
The original study reported 264 participants, but a correction published in 2022 clarified that the actual number was 263 participants5 7 . This attention to methodological accuracy underscores the scientific rigor applied to this field of research.
| Condition | Gambling Disorder Group | Non-Gambling Disorder Group | Significance |
|---|---|---|---|
| Cannabis Abuse | 92.9% | 74.5% | p = 0.008 |
| Cocaine Abuse | 73.8% | 34.2% | p < 0.001 |
| Anabolic Steroids Abuse | 31.0% | 11.9% | p = 0.003 |
| Antisocial Personality Disorder | 83.3% | 60.2% | p = 0.005 |
| Any Substance Abuse | 92.9% | 82.8% | p = 0.110 |

Cocaine abuse and failure to graduate from elementary and middle school on time emerged as factors independently associated with gambling disorder in regression analyses7 . This suggests that early educational interventions might serve as protective factors against later development of gambling problems in at-risk youth.
The Swedish study challenges some common assumptions about gambling-related crime. While we might expect gambling disorder to correlate primarily with financial crimes, the research found that offenders with gambling disorder were significantly more likely to have committed drug-related offenses and traffic violations7 .
This pattern suggests that the relationship between gambling and crime may be more nuanced than simple financial motivation.
More recent research supports this complexity. A 2024 Finnish study found that borderline personality traits were significantly associated with problem gambling among prisoners, while antisocial traits were linked to drug use problems4 . This highlights the importance of considering personality factors in understanding and treating gambling disorder in offender populations.
The high rates of comorbidity observed in these studies present both challenges and opportunities for treatment within correctional settings:
The finding that 52.4% of offenders with gambling disorder had committed illegal acts to finance their gambling provides direct evidence of the crime-gambling connection7 .
Understanding the relationship between gambling and criminal behavior requires specialized assessment tools and research methodologies.
| Tool/Method | Function | Application in Gambling-Crime Research |
|---|---|---|
| Structured Clinical Interviews (SCID-I/SCID-II) | Comprehensive diagnostic assessment for DSM disorders | Gold-standard for establishing psychiatric diagnoses in research settings3 |
| South Oaks Gambling Screen (SOGS) | Screening instrument for problem gambling | Most commonly used tool in prison gambling research2 |
| DSM Diagnostic Criteria Checklist | Symptom-by-symptom assessment of gambling disorder | Allows for precise diagnosis beyond screening tools3 |
| Wechsler Adult Intelligence Scale (WAIS) | Assessment of intellectual functioning | Identifies potential cognitive factors related to both gambling and offending3 |
| Problem Gambling Severity Index (PGSI) | Measures gambling problem severity | Used in population surveys to assess risk levels6 |
The compelling evidence connecting gambling disorder to criminal behavior, particularly among incarcerated populations, demands increased attention from researchers, clinicians, and policy makers. The Swedish prison study, despite its need for a minor correction in participant numbers, provides robust evidence that gambling disorder represents a significant concern in offender populations, characterized by complex psychiatric comorbidity and distinct criminal patterns.
As we continue to unravel the complex connections between gambling and crime, one thing becomes increasingly clear: addressing this hidden addiction within our justice system represents not just a matter of treatment, but one of public safety, social justice, and effective rehabilitation.
By bringing gambling disorder out of the shadows and into the light of evidence-based practice, we take an important step toward breaking the cycle of addiction and crime.
