18.3 Process (Behavioral) Addictions: Gambling Disorder, Gaming & Compulsive Behaviors
Key Takeaways
- Gambling disorder is the only behavioral addiction placed in the DSM-5-TR substance-related and addictive disorders chapter, requiring 4 or more of 9 criteria within 12 months.
- DSM-5-TR moved gambling disorder out of the impulse control disorders and removed the illegal acts criterion, leaving nine criteria rather than ten.
- Internet gaming disorder remains in the DSM-5-TR Section III conditions for further study, while ICD-11 recognizes gaming disorder as a formal diagnosis.
- Dopamine agonists used for Parkinson disease and restless legs syndrome cause impulse control disorders including pathological gambling, and the treatment is to reduce or stop the agonist.
- Gambling disorder carries one of the highest suicide attempt rates of any psychiatric condition, so suicide risk assessment is mandatory at every contact.
18.3 Process (Behavioral) Addictions: Gambling Disorder, Gaming & Compulsive Behaviors
Quick Answer: Gambling disorder is the only behavioral addiction included in the DSM-5-TR chapter on substance-related and addictive disorders. It requires 4 or more of 9 criteria in a 12-month period. DSM-5 moved it out of impulse control disorders and deleted the illegal-acts criterion. Internet gaming disorder remains in Section III (conditions for further study), while ICD-11 recognizes gaming disorder as a formal diagnosis. Dopamine agonists (pramipexole, ropinirole, rotigotine) cause iatrogenic gambling, and gambling disorder has among the highest suicide attempt rates in psychiatry.
The ANCB blueprint names process addictions explicitly within category E. Candidates who study only substances will miss these items.
1. Gambling Disorder: The Nine Criteria
Persistent and recurrent problematic gambling leading to clinically significant impairment or distress, with 4 or more of the following in 12 months:
- Needs to gamble with increasing amounts of money to achieve the desired excitement (tolerance)
- Restless or irritable when attempting to cut down or stop (withdrawal-like)
- Repeated unsuccessful efforts to control, cut back or stop
- Frequently preoccupied with gambling
- Often gambles when feeling distressed
- After losing money, often returns another day to get even ("chasing" losses)
- Lies to conceal the extent of involvement
- Has jeopardized or lost a significant relationship, job, or educational or career opportunity
- Relies on others to provide money to relieve desperate financial situations ("bailout")
Severity: mild 4 to 5 criteria; moderate 6 to 7; severe 8 to 9. Specify episodic or persistent, and in early remission (3 to under 12 months) or sustained remission (12 months or more).
Two changes candidates are tested on: DSM-5 reduced the criterion threshold from 5 to 4, removed the illegal-acts criterion (leaving 9 rather than 10), and relocated the diagnosis from impulse control disorders into the addictive disorders chapter based on shared neurobiology, phenomenology, comorbidity and treatment response.
2. Screening
| Tool | Items | Use |
|---|---|---|
| Lie/Bet questionnaire | 2 | Ultra-brief: ever lied about gambling; ever needed to bet more money |
| NODS-CLiP | 3 | Brief clinical screen |
| Problem Gambling Severity Index (PGSI) | 9 | Population and clinical severity; 8 or more indicates problem gambling |
| South Oaks Gambling Screen (SOGS) | 20 | Older, longer, still widely used |
Ask about sports betting and in-app purchases specifically. Mobile sports wagering and in-game loot boxes have changed the epidemiology substantially, moving gambling onto a phone that is available continuously and shortening the interval between impulse and wager to seconds.
3. Comorbidity and Suicide Risk
- High rates of co-occurring alcohol use disorder, tobacco use disorder, mood disorders, anxiety disorders and ADHD.
- Suicide attempt rates in gambling disorder are among the highest of any psychiatric condition, driven by acute financial catastrophe, shame and concealment.
- The financial crisis is frequently the presenting event: a spouse discovers hidden debt, a retirement account is emptied, or a bankruptcy is filed.
- APRN obligation: screen for suicidal ideation at every contact, ask directly about firearm access, and involve the family when the patient consents, because the financial and safety plan usually requires someone else.
4. The Iatrogenic Cause You Must Rule Out
Dopamine agonists — pramipexole, ropinirole, rotigotine, and to a lesser extent levodopa and the dopamine partial agonist aripiprazole — cause impulse control disorders: pathological gambling, compulsive shopping, hypersexuality and binge eating. Features:
- Onset after starting or increasing the agent, often in a person with no prior gambling history.
- Frequently not volunteered by the patient because of shame; must be asked about directly at every medication review.
- Treatment is to reduce or discontinue the dopamine agonist, in coordination with the prescribing neurologist or psychiatrist, after which the behavior usually remits.
Any new-onset gambling problem in a patient with Parkinson disease, restless legs syndrome, hyperprolactinemia, or on aripiprazole should trigger this review before any other intervention.
5. Treatment
| Modality | Evidence |
|---|---|
| Cognitive behavioral therapy | Best-supported treatment; targets cognitive distortions (illusion of control, gambler's fallacy, near-miss effect, selective recall of wins) |
| Motivational interviewing | Effective for engagement, often combined with CBT |
| Gamblers Anonymous | Twelve-step mutual help; GamAnon for family members |
| Self-exclusion programs | Voluntary casino and sportsbook bans; app blockers and bank gambling-transaction blocks |
| Financial counseling and restructuring | Essential and frequently omitted; removing access to funds is a concrete relapse-prevention intervention |
| Naltrexone 50 to 100 mg daily | Randomized data support benefit, especially with a family history of alcoholism; not FDA-approved for this indication |
| Nalmefene | Positive trials; not marketed in the United States for this use |
| Lithium | Some benefit in gambling with bipolar spectrum comorbidity |
| SSRIs | Inconsistent; treat comorbid depression or anxiety rather than gambling itself |
No medication is FDA-approved for gambling disorder. The defensible plan is CBT plus mutual help plus financial access restriction, with naltrexone as an off-label adjunct when craving is prominent.
6. Gaming and Other Proposed Behavioral Addictions
| Condition | Status |
|---|---|
| Internet gaming disorder | DSM-5-TR Section III, conditions for further study; proposed 9 criteria with a threshold of 5 |
| Gaming disorder | Recognized in ICD-11 — impaired control, increasing priority over other interests, continuation despite negative consequences, usually for at least 12 months |
| Compulsive sexual behavior disorder | Recognized in ICD-11 as an impulse control disorder, deliberately not classified as an addiction |
| Compulsive buying, exercise, and food addiction | Not recognized diagnoses; described in the literature but without formal criteria |
Exam trap: "sex addiction" and "food addiction" are not DSM-5-TR diagnoses. Compulsive sexual behavior disorder exists in ICD-11 but as an impulse control disorder, explicitly not as an addictive disorder. Only gambling disorder sits in the DSM addictive disorders chapter.
