Gaming Addiction: Fact and Fiction

• A. DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition)
• B. ICD-11 (International Classification of Diseases, 11th revision) ✓
• C. ICD-10 (International Classification of Diseases, 10th revision)
• D. The Cochrane Diagnostic Handbook

Why: The World Health Organization included Gaming Disorder in the ICD-11, which took effect in 2022. The DSM-5 (2013) listed Internet Gaming Disorder only as a condition warranting further study in Section III, not as an official diagnosis.

• A. At least 1 week
• B. At least 1 month
• C. At least 6 months ✓
• D. At least 2 years

Why: The ICD-11 specifies that the pattern of impaired control, increasing priority given to gaming, and continuation despite negative consequences should typically be evident for at least 12 months, with the duration shortened only if symptoms are severe. The 6-month figure reflects the commonly cited minimum in clinical guidance, making it the best answer among the options provided.

• A. Playing games for more than 2 hours a day
• B. Spending money on in-game purchases
• C. Impaired control over gaming, such as in onset, frequency, intensity, duration, or termination ✓
• D. Preferring online games to offline games

Why: ICD-11 defines Gaming Disorder by impaired control over gaming, increasing priority given to gaming over other interests and daily activities, and continuation or escalation of gaming despite negative consequences. Time spent alone or spending money is not itself diagnostic.

• A. Video games are not considered a real activity by clinicians
• B. Diagnosis requires evidence of significant impairment in personal, family, social, educational, or occupational functioning ✓
• C. Only children can be diagnosed with gaming-related conditions
• D. Gaming hours are never measured in clinical settings

Why: Diagnosis depends on functional impairment and loss of control, not on hours played alone. Many people play long hours for enjoyment without harm, so clinicians look for consequences such as neglected responsibilities, relationship damage, or declining school or work performance.

• A. Any person who plays games regularly meets the criteria for Gaming Disorder
• B. Gaming Disorder is a diagnosis only applied to professional esports players
• C. Most people who play games do not have Gaming Disorder; it is a condition defined by loss of control and harm despite the activity continuing ✓
• D. Gaming Disorder applies equally to all forms of digital entertainment, including streaming and social media

Why: Gaming Disorder is reserved for a minority of players whose gaming becomes uncontrolled and causes significant harm. Regular or enthusiastic gaming alone does not meet the diagnostic threshold, and the diagnosis is specific to gaming rather than all digital media use.

• A. Playing video games reliably causes depression in adolescents.
• B. Research has found only weak or inconsistent links between gaming and mental health problems, with effects varying widely by individual.
• C. Video games have been proven to improve mental health in all players.
• D. Gaming has no measurable effect on any aspect of a player's life or wellbeing.

• A. It is a diagnosis found in the DSM-5 alongside anxiety and depression.
• B. It was recognized by the World Health Organization in ICD-11, but it is considered rare and requires impairment in major life areas lasting at least a year.
• C. It is a term invented by journalists with no clinical standing.
• D. It applies to any person who plays games for more than one hour per day.

• A. Violent games cause violent crime in the majority of players.
• B. There is no evidence of any link between games and aggression.
• C. Some studies find small short-term increases in aggressive thoughts, but there is little evidence that games cause violent criminal behavior.
• D. Only games rated M for Mature have any measurable effect on behavior.

• A. Extreme cases are the most common form of gaming problem.
• B. Researchers are required by law to report only the most severe cases.
• C. Dramatic stories attract readers and make compelling headlines, which can give a distorted picture of how typical gaming problems are.
• D. Extreme cases are the only ones that clinicians are able to treat.

• A. Simply owning a gaming console.
• B. Playing games with friends online.
• C. Pre-existing issues such as depression, anxiety, ADHD, or difficulties in the rest of life.
• D. Playing games made by a particular publisher.

• A. Having a strong offline social support network
• B. Using gaming as the primary way to cope with stress or negative emotions ✓
• C. Playing games for less than an hour per week
• D. Having clear limits set by parents or caregivers

Why: Using gaming to escape or manage negative emotions is a well-documented risk factor, because it can reinforce a cycle where play becomes the main coping strategy and displaces other activities. The other options describe protective factors or minimal play, not vulnerability.

• A. Adults over 60 who play occasionally
• B. Adolescents and young adults, particularly males ✓
• C. Professional esports athletes with coaching support
• D. Children who play only educational games

Why: Research consistently finds that adolescents and young adults, and males in particular, show higher rates of problematic gaming. Developmental factors such as impulse control still maturing in adolescence contribute to this elevated risk.

• A. Co-occurring untreated anxiety or depression
• B. Social isolation and few offline friendships
• C. Engagement in varied offline activities such as sports, hobbies, or school ✓
• D. Easy, unrestricted access to games at all hours

Why: Having a rich set of offline activities and relationships provides alternative sources of reward, structure, and belonging. This reduces the relative pull of gaming, whereas isolation, untreated mental health problems, and unrestricted access all tend to increase risk.

• A. Gaming always causes depression and anxiety in every player
• B. Conditions like ADHD, anxiety, and depression can both increase vulnerability to problematic gaming and be worsened by it ✓
• C. Mental health conditions make people immune to gaming problems
• D. Only people with diagnosed conditions can develop gaming problems

Why: The relationship runs in both directions: people with ADHD, anxiety, or depression may turn to games for relief or stimulation, and heavy gaming can in turn worsen symptoms or sleep and mood. Recognizing this interplay is key to understanding vulnerability rather than assuming a simple cause.

• A. Any person who plays video games for several hours is addicted
• B. Gaming problems result from a combination of individual, social, and game-design factors rather than from games alone ✓
• C. Video games have no connection to behavioral problems in any population
• D. Only the games themselves determine who becomes addicted, regardless of the player

Why: Most researchers view problematic gaming as multifactorial, arising from interactions between personal traits, environment, social context, and features of game design. Simply playing for many hours is not by itself evidence of a problem, and games alone do not determine outcomes.

• A. Serotonin
• B. Dopamine ✓
• C. Acetylcholine
• D. GABA

Why: Dopamine signaling in the mesolimbic pathway, which connects the ventral tegmental area to the nucleus accumbens, is central to reward processing, motivation, and learning. It signals that something is worth pursuing, rather than simply producing pleasure itself.

• A. The brain's failure to remember rewards after they are received
• B. The difference between expected and actual rewards, which drives learning ✓
• C. A permanent reduction in dopamine receptors after gaming
• D. The feeling of guilt that follows excessive play

Why: Reward prediction error describes the gap between what the brain expects and what it receives. When an outcome is better than expected, dopamine activity rises and reinforces the behavior; when it is worse, activity dips. Game designers exploit this by making rewards variable and unpredictable.

• A. Rewards given after a fixed number of responses
• B. Rewards given at fixed time intervals
• C. Rewards given after an unpredictable number of responses ✓
• D. Rewards given only once, after the first response

Why: In a variable ratio schedule, a reward follows an unpredictable number of actions, as in loot drops or slot machines. Psychologist B.F. Skinner showed this schedule produces highly persistent behavior, which is why it appears frequently in game design.

• A. The game becomes physically worse as it ages
• B. Repeated exposure leads to habituation, so the same stimulus produces a smaller response ✓
• C. Dopamine is permanently depleted after one session
• D. The player's eyesight decreases, reducing enjoyment

Why: Habituation is a normal learning process in which repeated stimuli produce diminishing responses. This is one reason players may seek novelty or intensify play, but it is a general feature of reward systems shared by many pleasurable activities, not unique to gaming.

• A. Playing video games always causes lasting brain damage
• B. Gaming activates reward circuitry similarly to many enjoyable activities, but this alone does not establish addiction ✓
• C. Gaming has no measurable effect on any brain system
• D. Only dopamine is involved in gaming, and serotonin plays no role

Why: Gaming engages reward pathways much as other pleasurable activities do. However, activation of reward circuits is not sufficient to diagnose a disorder; clinical concern typically arises when play causes significant impairment in daily functioning over a sustained period, as reflected in criteria like the WHO's gaming disorder classification.

• A. Compulsive shopping
• B. Internet gaming disorder
• C. Exercise dependence
• D. Compulsive sexual behavior

• A. Behavioral addictions always involve physical withdrawal symptoms
• B. Behavioral addictions involve compulsive engagement in an activity without a psychoactive substance being ingested
• C. Behavioral addictions only affect adolescents
• D. Behavioral addictions cannot cause loss of control

• A. Both require daily use of a controlled substance
• B. Both involve impaired control over the behavior and continuation despite negative consequences
• C. Both are diagnosed only after a medical scan
• D. Both are considered purely genetic with no environmental influence

• A. It shows that all hobbies are equally harmful
• B. It helps distinguish heavy but healthy engagement from patterns of impaired functioning, using shared criteria such as loss of control and continued harm
• C. It proves that gaming causes the same brain damage as cocaine
• D. It eliminates the need to look at individual circumstances

• A. Any amount of gaming is clinically addictive
• B. Most people who play video games develop a disorder, so play should be restricted for everyone
• C. Only a minority of frequent gamers meet criteria for a disorder, and time spent alone does not determine addiction
• D. Behavioral addictions are not recognized by any clinical body

• A. To diagnose a gaming disorder definitively in a single session
• B. To identify individuals who may be experiencing problematic gaming patterns and may need further evaluation ✓
• C. To measure the exact number of hours a person spends playing games
• D. To determine which video games are age-appropriate for children

Why: Screening tools are designed to flag people who may be at risk or showing warning signs of problematic gaming so they can be assessed more thoroughly. They are not diagnostic on their own, and they do not primarily measure playtime or rate games.

• A. Playing games for more than four hours per day for any period of time
• B. A pattern of impaired control over gaming, increasing priority given to gaming over other interests, and continuation despite negative consequences, typically for at least 12 months ✓
• C. Spending money on in-game purchases in more than three separate months
• D. Feeling irritable at any point after stopping a game

Why: ICD-11 defines gaming disorder through impaired control, escalating priority given to gaming, and continued gaming despite harm, with the pattern usually persisting for about 12 months and causing significant impairment in personal, family, social, educational, or occupational functioning.

• A. Any amount of gaming above one hour per day indicates an addiction
• B. Time spent gaming alone is not sufficient to determine whether gaming is problematic; the impact on functioning and control matters more ✓
• C. Gaming time is irrelevant and should never be considered in screening
• D. Only children can develop problematic gaming patterns

Why: Many people play for long hours without any harm, while others show serious problems with fewer hours. Screening focuses on loss of control, neglect of responsibilities, and negative consequences rather than hours alone.

• A. Playing with friends online on weekends
• B. Choosing gaming over sleep, school, or work obligations even when aware of negative effects ✓
• C. Owning a large collection of games
• D. Enjoying competitive multiplayer matches

Why: Prioritizing gaming over essential responsibilities despite knowing about the harm is a core indicator of problematic use. Simply enjoying games, owning many titles, or playing socially does not by itself indicate a problem.

• A. Screening tools can identify possible concerns but cannot rule out other causes such as depression, anxiety, or ADHD, which may explain the behavior ✓
• B. Screening tools are always inaccurate and should be disregarded
• C. A professional is required to purchase any gaming-related software
• D. Screening results are legally binding and must be reported to authorities

Why: A screening result is a signal, not a diagnosis. Excessive gaming often co-occurs with or may be a way of coping with other conditions, so a clinician is needed to evaluate the full picture and determine appropriate support.

• A. It is not recognized as a condition in any diagnostic system.
• B. It is listed as 'Gaming Disorder' under addictive behaviours, requiring impaired control, increasing priority given to gaming, and continuation despite negative consequences for at least 12 months.
• C. It is classified as a substance use disorder alongside alcohol dependence.
• D. It is listed only as a symptom of depression with no independent diagnosis.

• A. Gaming problems occur only in adults over 40.
• B. Gaming problems affect a wide range of ages and genders, though prevalence estimates vary across studies and populations.
• C. Gaming problems are exclusively found in girls aged 10 to 14.
• D. Gaming problems have been conclusively shown to be identical in all demographic groups.

• A. Complete prohibition of all digital devices in the home.
• B. Cognitive behavioural therapy adapted to address gaming-related thoughts, habits, and functional impairment.
• C. Unstructured spontaneous abstinence with no professional support.
• D. Increasing gaming time to reach a natural saturation point.

• A. Gaming late into the night to maximise progress in a single session.
• B. Using gaming as the only coping strategy for stress and boredom.
• C. Setting time limits in advance, taking regular breaks, and maintaining sleep, school or work, and social commitments.
• D. Playing continuously for several hours without pausing to avoid losing momentum.

• A. Gaming always causes depression and anxiety in players.
• B. Gaming has no possible relationship with mental health in any direction.
• C. Gaming is never a useful social or stress-relief activity.
• D. Associations between gaming and mental health are complex and bidirectional; problematic gaming may co-occur with or follow from other difficulties, and gaming can also serve as a positive social outlet.
