Focus on Gambling and Behavioral Addictions Notes on Behavioral Addictions

Evolving Perspectives on Behavioral Addictions

The diagnostic understanding of excessive behaviors has shifted from the DSM-IV classification of Impulse Control Disorders—which included conditions like trichotillomania, pyromania, and kleptomania—to the DSM-5 category of Addiction and Related Disorder. Under this updated framework, what was previously known as pathological gambling is now formally recognized as gambling disorder. Furthermore, the World Health Organization has included gaming disorder in the ICD-11, defining it as a pattern of digital or video-gaming behavior characterized by impaired control and the prioritization of gaming over daily life activities despite the occurrence of negative consequences. The DSM-5 also identifies Internet Gaming Disorder (IGD) as an area necessitating further clinical research.

Neurobiological Links and Practice Implications

There is significant evidence that behavioral addictions resemble substance-related disorders in their phenomenology, genetic contributions, neurobiological mechanisms, and response to treatment. The reward deficiency hypothesis suggests that certain individuals derive less satisfaction from natural rewards, leading them to engage in dopamine-activating behaviors to compensate. From a clinical perspective, the focus should be on the meaning and function of the behavior rather than the addiction label itself. Practitioners must consider that disturbed early attachment experiences can make individuals more susceptible to forming reinforcing relationships with potent substances or behaviors. Addressing these issues involves not only stopping the behavior but also establishing healthy coping mechanisms to replace avoidance strategies.

Risks and Demographics of Online Gambling

Research conducted by Young, M. M., et al. ($2025$) for the Canadian Centre on Substance Use and Addiction indicates that online gambling carries substantially higher risks compared to traditional forms like the lottery. Online gamblers are $10$ times more likely to exceed lower-risk thresholds ($93.8\%$ vs. $9.4\% ​$) and $45.3$ times more likely to meet the criteria for problem gambling ($40.8\%$ vs. $0.9\% ​$). Among young adults aged $18$ to $29$, roughly one in three ($32.0\% ​$) report gambling online. In this demographic, $69.4\%$ of online gamblers met the criteria for problem gambling, and they were $6.1$ times more likely to reach this threshold than adults aged $65+$, where the rate was $11.4\% ​$.

Assessment and Treatment Considerations

A comprehensive clinical assessment for behavioral addictions includes a review of the history, frequency, and impacts of the behavior, sowie family history, legal circumstances, and co-occurring mental health issues. Tools such as the Problem Gambling Severity Index, GAIN-SS, and MMS are utilized for screening and documentation. Treatment strategies often employ Motivational Interviewing (MI) to build commitment, alongside Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT). While the pharmacological agent Naltrexone is occasionally used for gambling, a primary goal of care is treating underlying mental health issues, which often leads to behavioral improvement. It is also imperative to involve families and address cultural implications within the treatment plan.
