Behavioral addiction — also called a process addiction — is a compulsive pattern of engagement in a rewarding behavior that produces loss of control, escalation, and continued participation despite serious negative consequences, driven by the same dopamine reward pathways that underlie substance use disorders. Gambling disorder is the only behavioral addiction officially recognized in the DSM-5, yet an estimated 2.5 million U.S. adults meet criteria for a severe gambling problem annually, with 5 to 8 million more exhibiting significant problematic behavior. (NCPG)

The WHO’s ICD-11 added gaming disorder as a second formally recognized behavioral addiction in 2019, reflecting growing clinical evidence. Behavioral addictions are treatable, and most people who engage in sustained, evidence-based care — including CBT, contingency management, and motivational interviewing — achieve significant recovery.

Key Takeaways

• Shared neurobiology with substance addiction: Behavioral addictions activate the same dopamine reward circuits in the brain as drugs and alcohol — producing tolerance, cravings, and withdrawal-like symptoms when the behavior is stopped. (NIDA)
• Scale of problem gambling: Nearly 20 million U.S. adults reported at least one indicator of problematic gambling behavior “many times” in the past year. (NCPG NGAGE 3.0, 2024)
• Co-occurring disorders: Roughly 50% of problem gamblers in treatment meet current or lifetime criteria for a substance use disorder — and 8.1% of all U.S. adults live with both a mental illness and a substance use disorder simultaneously. (SAMHSA; NAMI, 2025)
• Treatment gap: Only about 1 in 5 people who need substance use treatment receive it — a pattern that mirrors treatment access for behavioral addictions. (SAMHSA, 2025)
• Stigma barrier: Only 39% of Americans view gambling addiction as “very serious,” compared to 62% for drug addiction and 55% for alcoholism — stigma that reduces help-seeking in all behavioral addiction categories. (NCPG, 2024)
• Youth vulnerability: 65% of U.S. adults aged 21 and older report participating in at least one form of gambling before age 21 — and children and teens are at higher risk for developing a gambling addiction than adults. (NCPG, 2026; NCPG)
• Treatable condition: Behavioral therapies including CBT, contingency management, and motivational interviewing have demonstrated effectiveness for behavioral addictions — the same approaches that work for substance use disorders. (NIMH)

What Is Behavioral Addiction?

A behavioral addiction is a compulsive disorder in which a person becomes dependent on a specific behavior or activity — rather than a chemical substance — to produce feelings of pleasure, relief, or escape. The behavior activates the brain’s natural reward system, releasing dopamine in circuits that govern motivation and reinforcement. (NIDA) Over time, the brain adapts by reducing the reward circuit’s response — producing tolerance, which requires the person to engage more frequently or intensely to achieve the same effect.

Behavioral addictions share the core features of substance use disorders: loss of control over the activity, continued engagement despite negative consequences, preoccupation with the behavior, and withdrawal-like distress when access is restricted. The NIDA explains that dopamine signals cause changes in neural connectivity that make it progressively easier to repeat the behavior — until what began as a voluntary choice becomes a compulsive, near-automatic response. (NIDA)

The term process addiction is used interchangeably with behavioral addiction in clinical settings. Other classifications include non-substance addiction, impulse control disorder, and behavioral dependence. The APA’s DSM-5 formally recognizes gambling disorder as a behavioral addiction, while the WHO’s ICD-11 additionally recognizes gaming disorder. Both classification bodies acknowledge that research on other behavioral addiction categories — including compulsive sexual behavior and compulsive buying — is ongoing.

How Behavioral Addiction Affects the Brain

Behavioral addictions hijack the brain’s natural reward pathway — the same mesolimbic dopamine system that drugs exploit. When a person engages in a rewarding behavior (gambling, gaming, sexual activity), the nucleus accumbens releases dopamine, signaling that something important is happening and reinforcing the desire to repeat the activity. (NIDA) This process is how the brain normally reinforces beneficial behaviors like eating and socializing — but behavioral addictions subvert it through disproportionate, artificial activation.

With repeated compulsive engagement, the brain adapts by reducing dopamine receptor sensitivity. The result is tolerance — the behavior that once produced intense satisfaction now produces less, requiring escalation in frequency or intensity to feel the same effect. (NIDA) Simultaneously, the prefrontal cortex — the brain region responsible for decision-making, judgment, and self-control — becomes progressively less effective at overriding impulses. This is why behavioral addiction is classified as a brain disease, not a moral failing or lack of willpower.

The environmental cues associated with the addictive behavior become deeply encoded in the brain’s memory circuits. Exposure to these cues — a casino, a smartphone, a stressful emotion — can trigger intense cravings even after extended periods of abstinence. NIDA describes this learned reflex as capable of lasting for years after cessation in individuals with substance use disorders, and the same mechanism applies to behavioral addictions. (NIDA)

Types of Behavioral Addiction

The DSM-5 and ICD-11 recognize gambling disorder and gaming disorder as formal diagnoses. Several other behavioral patterns are under active clinical investigation for potential future classification.

Behavioral Addiction	Diagnostic Status	Core Behavioral Pattern
Gambling Disorder	Formally recognized — DSM-5	Persistent, recurrent problematic gambling causing significant impairment or distress
Gaming Disorder	Formally recognized — ICD-11 (WHO, 2019)	Impaired control over gaming; gaming takes priority over other life interests
Compulsive Sexual Behavior Disorder	Recognized — ICD-11	Inability to control intense sexual urges despite distress or impairment
Compulsive Buying / Shopping	Under clinical investigation	Uncontrolled purchasing behavior driven by emotional regulation needs
Problematic Internet Use	Under clinical investigation	Excessive, uncontrolled non-gaming internet use causing functional impairment
Exercise Addiction	Under clinical investigation	Compulsive exercise despite injury, illness, or relational harm
Food Addiction	Under clinical investigation	Loss of control over eating specific foods, with tolerance and withdrawal features

Gambling Disorder

Gambling disorder is the only behavioral addiction formally classified in the DSM-5. It is characterized by persistent and recurrent gambling that causes clinically significant impairment or distress, meeting at least four of nine diagnostic criteria within a 12-month period — including preoccupation, tolerance, failed attempts to cut back, chasing losses, and lying about gambling. (NCPG) An estimated 2.5 million U.S. adults (1%) meet criteria for severe gambling disorder in any given year, with another 5 to 8 million exhibiting mild-to-moderate problematic behavior. (NCPG) The disorder is highly co-occurring with substance use disorders: 50% of problem gamblers in treatment also meet criteria for a substance use disorder. (SAMHSA)

Gaming Disorder

Gaming disorder was added to the WHO’s ICD-11 in 2019. It is defined by impaired control over gaming, increasing priority given to gaming over other activities, and continuation or escalation despite negative consequences — lasting at least 12 months. (WHO) The DSM-5 lists internet gaming disorder under “Conditions for Further Study,” acknowledging emerging evidence without yet granting full diagnostic status. The disorder is most prevalent among adolescents and young adults, where it frequently co-occurs with depression and social anxiety.

Other Behavioral Patterns

Compulsive sexual behavior disorder is recognized in the ICD-11 as a failure to control intense sexual impulses despite significant distress or impairment. Compulsive buying, problematic internet use, exercise addiction, and food addiction share the core addiction features of impaired control and continued behavior despite harm — but await further clinical validation before receiving formal diagnostic codes. WHO and NIMH researchers are actively studying these patterns as the classification of behavioral addictions continues to evolve. (NIMH)

Signs and Symptoms of Behavioral Addiction

Behavioral addiction symptoms mirror the clinical criteria for substance use disorders. The DSM-5 and ICD-11 frameworks identify the following core indicators:

• Loss of control: Repeated, unsuccessful attempts to reduce or stop the behavior
• Preoccupation: Persistent thoughts about the behavior — planning, anticipating, or recovering from it
• Tolerance: Needing to engage more frequently or intensely to achieve the same emotional effect
• Withdrawal-like symptoms: Restlessness, irritability, anxiety, or mood disturbance when access to the behavior is restricted (NCPG)
• Continued engagement despite consequences: Persisting in the behavior despite job loss, relationship damage, financial harm, or physical health problems
• Escape or mood regulation: Using the behavior to escape problems, relieve feelings of helplessness, guilt, anxiety, or depression
• Concealment: Lying to family members, partners, or employers about the extent of engagement (NCPG)
• Reliance on others: Depending on others to relieve financial crises caused by the behavior

Social and occupational functioning deteriorates as the behavior consumes increasing time and mental energy. Relationships suffer through deception, emotional unavailability, and financial harm. NIMH notes that many people with behavioral addictions also have co-occurring mental health conditions — and that mental disorders can alter the brain in ways that make rewarding behaviors feel more compelling, further increasing behavioral addiction risk. (NIMH)

Causes and Risk Factors

Behavioral addiction develops through the same interplay of genetic, environmental, and developmental factors that drive substance use disorders. NIDA confirms that no single factor predicts addiction — the risk increases when multiple factors converge. (NIDA)

Level	Risk Factors	Protective Factors
Biological	Family history of addiction, dopamine system variants, impulsivity traits	Healthy reward regulation, strong impulse control
Psychological	Depression, anxiety, ADHD, trauma history, low distress tolerance	Emotion regulation skills, effective coping strategies
Developmental	Early exposure to gambling or addictive behaviors; adolescent brain development (NCPG)	Late onset of exposure; parental monitoring
Environmental	Easy access (online gambling, mobile gaming), social normalization, advertising	Social support, responsible gambling/gaming messaging, community connectedness

Genetics contributes meaningfully to addiction vulnerability. Family studies show that gambling problems cluster across generations, and NCPG reports that many people in treatment for gambling disorder have a parent with a drinking or gambling problem. (NCPG) NIDA states that the brain areas most involved in decision-making, judgment, and self-control — which govern impulse control over addictive behaviors — are still developing through early adulthood, making adolescents especially vulnerable. (NIDA)

Co-occurring mental health conditions drive a significant proportion of behavioral addiction cases. NIMH explains that mental disorders can alter the brain in ways that make rewarding behaviors feel more compelling, increasing addiction risk — while the reverse is also true, since compulsive behaviors worsen psychiatric symptoms over time. (NIMH) Depression, anxiety, ADHD, and trauma histories are among the most common co-occurring conditions in behavioral addiction.

Effects of Behavioral Addiction

Untreated behavioral addictions produce serious, escalating consequences across every domain of life. NCPG identifies bankruptcy, legal problems, job loss, family breakdown, and suicidal ideation as outcomes in severe gambling disorder cases. (NCPG) The same pattern applies across other behavioral addiction categories — the mechanism differs but the functional damage does not.

• Financial: Problem gambling and compulsive buying generate direct economic losses, mounting debt, bankruptcy, and financial dependence on family members
• Occupational: Preoccupation with the addictive behavior reduces productivity, increases absenteeism, and leads to employment termination
• Relational: Deception, broken promises, and emotional unavailability erode trust in marriages and family relationships; children of individuals with behavioral addictions may experience developmental disruption
• Legal: Gambling disorder in particular is associated with fraud, theft, and other criminal behavior driven by the need to fund the addiction
• Mental health: Co-occurring depression, anxiety, and suicidal ideation are documented outcomes of untreated gambling disorder and other behavioral addictions (NCPG)
• Physical health: Chronic stress from compulsive behavior disrupts sleep, immune function, and cardiovascular health; physical care is often neglected during active addiction

The economic burden of behavioral addiction extends beyond individuals. NAMI reports that serious mental illness — which co-occurs with behavioral addiction at high rates — causes $193.2 billion in lost earnings annually across the U.S. economy. (NAMI) Depression and anxiety disorders, frequently co-occurring with behavioral addictions, cost the global economy an estimated $1 trillion per year in lost productivity. (WHO, 2025)

Treatment for Behavioral Addiction

Behavioral addictions are treatable with evidence-based approaches that parallel those used for substance use disorders. NIMH identifies cognitive behavioral therapy, contingency management, and motivational interviewing as the core behavioral therapies proven effective for co-occurring addiction and mental health conditions. (NIMH) Treatment is most effective when it addresses both the compulsive behavioral pattern and any underlying mental health conditions simultaneously.

Treatment	Mechanism	Best Used For
Cognitive Behavioral Therapy (CBT)	Identifies and restructures thought patterns and behaviors that trigger compulsive engagement; builds coping skills and relapse prevention strategies	Gambling disorder, gaming disorder, compulsive shopping, internet use
Motivational Interviewing (MI)	Resolves ambivalence about change by exploring personal values and consequences of the addictive behavior	Early-stage engagement; clients resistant to treatment
Contingency Management	Uses structured positive reinforcement (rewards) for meeting behavioral abstinence goals	Gambling, gaming, and other behavioral addictions with measurable outcomes
Dialectical Behavior Therapy (DBT)	Builds emotional regulation, distress tolerance, and mindfulness skills	Behavioral addictions co-occurring with borderline personality disorder, trauma, self-harm
Family Therapy	Addresses relational dynamics, enabling patterns, and family-system contributions to addiction maintenance	Adolescent behavioral addiction; gambling disorder affecting families
Integrated Dual Diagnosis Treatment	Treats co-occurring mental illness and behavioral addiction within a single, unified care plan	Any behavioral addiction with co-occurring depression, anxiety, PTSD, or SUD
Support Groups (e.g., Gamblers Anonymous)	Peer support, accountability, and shared recovery experience using a 12-step or alternative framework	Gambling disorder; complement to professional treatment

For behavioral addictions co-occurring with a substance use disorder — which applies to roughly half of people in treatment for gambling disorder — addressing both disorders simultaneously within an integrated care plan produces the best outcomes. (SAMHSA) SAMHSA’s evidence-based practices resource center supports integrated treatment as the standard of care for co-occurring conditions. Medications may play a supporting role where co-occurring mental health conditions require pharmacological intervention alongside behavioral therapy. (NIMH)

Despite the availability of effective treatment, only 15% of Americans have ever been asked about their gambling behavior by a primary care provider — a missed opportunity for early intervention at scale. (NCPG, 2026) SAMHSA’s National Helpline — 1-800-662-4357 — provides free, confidential 24/7 referrals for mental health and substance use treatment, including behavioral addiction. The National Problem Gambling Helpline — 1-800-GAMBLER — offers 24/7 crisis support specifically for gambling disorder. (NCPG)

Frequently Asked Questions About Behavioral Addiction

Is behavioral addiction a real diagnosis?

Yes — partially. Gambling disorder is formally recognized in the DSM-5, and gaming disorder and compulsive sexual behavior disorder are recognized in the WHO’s ICD-11. These classifications mean they carry the same clinical weight as substance use disorders in terms of diagnosis, insurance coverage eligibility, and treatment protocols. Other behavioral addiction patterns — including compulsive buying, exercise addiction, and food addiction — are recognized as clinically significant conditions under active research, but do not yet have their own DSM-5 diagnostic codes. (NCPG) The absence of a formal code does not mean the condition is less real — it means classification is still evolving.

How is behavioral addiction different from a bad habit?

The distinction lies in control, consequences, and compulsion. A habit is a voluntary behavior pattern that can be changed with effort and motivation. A behavioral addiction involves loss of control over the behavior despite genuine attempts to stop, continued engagement even when it causes serious harm to relationships, finances, or health, and distress or withdrawal-like symptoms when the behavior is restricted. NIDA identifies impaired control in the face of negative consequences — not frequency alone — as the defining feature of addiction. (NIDA) Many people gamble, game, or shop frequently without meeting any criteria for addiction. The clinical threshold is crossed when the behavior becomes compulsive and harmful.

Can behavioral addiction co-occur with substance use disorder?

Yes — and it does so at high rates. Approximately 50% of people in treatment for gambling disorder also meet current or lifetime criteria for a substance use disorder. (SAMHSA) This co-occurrence reflects shared underlying vulnerabilities — including reward circuit dysfunction, impulsivity, and difficulty tolerating negative emotional states. NIMH confirms that mental disorders (including behavioral addiction) and substance use disorders are often mutually reinforcing: each condition can worsen the other and increase relapse risk. (NIMH) Integrated dual-diagnosis treatment that addresses both disorders within a single care plan consistently produces better outcomes than treating each in isolation.

Who is most at risk for behavioral addiction?

Several groups face heightened risk. Young adults aged 18–24 have the highest rates of gambling participation and problematic gambling behavior. (NCPG) Children and teenagers are at higher risk than adults because their decision-making and impulse control systems are still developing — and individuals who start gambling at a young age are significantly more likely to develop a disorder later in life. (NCPG; NIDA) People with family histories of addiction, co-occurring mental health conditions (especially depression, anxiety, or ADHD), and those with easy access to gambling or gaming platforms also face elevated risk. Online and mobile access to gambling significantly intensifies that risk — one study of online sports gamblers found that 16% met clinical criteria for gambling disorder. (NCPG Sports Wagering Review)

Does behavioral addiction treatment work?

Yes. Evidence-based treatments — particularly CBT, motivational interviewing, and contingency management — have demonstrated effectiveness for gambling disorder, gaming disorder, and related behavioral addictions. NIMH supports these same modalities for co-occurring substance use and mental health conditions. (NIMH) NIDA confirms that treatment approaches tailored to each patient’s behavioral patterns and co-occurring medical, mental, and social problems lead to continued recovery. (NIDA) A significant barrier to treatment is skepticism about its effectiveness — NCPG found that 37% of people engaged in risky gambling behavior believe recovery is unlikely, more than twice the rate of the general gambling population. (NCPG, 2024) The evidence clearly shows this skepticism is unfounded.

How does online gambling and gaming increase behavioral addiction risk?

Online and mobile access removes the practical barriers — time, travel, operating hours — that previously limited exposure to addictive behaviors. For gambling specifically, NCPG’s research on sports betting finds that the rate of gambling problems among sports bettors is at least twice as high as among gamblers in general, and when conducted online, one study found 16% of online sports gamblers met clinical criteria for gambling disorder with another 13% showing some signs. (NCPG Sports Wagering Review) NCPG also highlights that parlay betting nearly doubled from 17% of sports bettors in 2018 to 30% in 2024 — raising particular concerns about loss-chasing behaviors. (NCPG NGAGE 3.0, 2024) Online access is convenient, private, continuous, and algorithmically optimized to maximize engagement — all factors that elevate addiction risk.

What is the first step to getting help for behavioral addiction?

The first step is a clinical assessment by a licensed mental health professional who can diagnose the behavioral addiction, identify any co-occurring mental health or substance use conditions, and recommend the appropriate level of care. Most people can begin with an outpatient evaluation. For those unsure where to start: SAMHSA’s National Helpline (1-800-662-4357) provides free, confidential 24/7 referrals for mental health and substance use treatment. (SAMHSA) For gambling disorder specifically, the National Problem Gambling Helpline (1-800-GAMBLER) offers 24/7 crisis support and treatment connections. (NCPG) Most health insurance plans are legally required to cover mental health and behavioral addiction treatment as essential health benefits under the Affordable Care Act.

Summary: Behavioral addiction is a clinically recognized, neurobiologically grounded disorder in which compulsive engagement in reward-producing behaviors — most formally, gambling and gaming — causes loss of control, tolerance, withdrawal-like symptoms, and serious life consequences, all of which respond to evidence-based treatment including CBT, motivational interviewing, and integrated dual-diagnosis care.
