Summary
Pathological internet use (PIU) affects some users, leading to negative psychosocial outcomes. Current research highlights limited prevalence data and a need for reliable diagnostic tools for this condition.
Area of Science:
- Psychology
- Public Health
- Digital Media Studies
Background:
- Internet use has a 40-year history, with some users exhibiting a loss of control over usage frequency and duration.
- Excessive internet engagement and behavioral narrowing can result in significant psychosocial consequences, termed pathological internet use (PIU).
Purpose of the Study:
- To conduct a systematic literature review on pathological internet use (PIU) since 1996.
- To present the main findings regarding PIU prevalence, diagnosis, and treatment.
Main Methods:
- Systematic review of literature published since 1996.
- Analysis of prevalence data and diagnostic instrument methodologies.
Main Results:
- Prevalence rates for PIU internationally range from 1.5% to 8.2%, though data is limited by methodological challenges and heterogeneous diagnostic tools.
- High comorbidity of PIU with psychiatric disorders like affective disorder and ADHD is reported in patient samples.
- Current PIU treatment approaches are adapted from substance use disorder therapies, but lack robust evidence due to insufficient research.
Conclusions:
- Reliable and valid diagnostic instruments are crucial for accurate PIU assessment and international comparison.
- Further research is needed to understand shared risk factors or the secondary nature of PIU in relation to other psychiatric disorders.
- Evidence-based treatment recommendations for PIU cannot be made due to a lack of methodologically sound studies.

01:27Diagnostic and Statistical Manual of Mental Disorders (DSM)
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...
01:19Introduction to Psychological Disorders
Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

01:23Binge Eating Disorders
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
01:30Bulimia Nervosa
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
01:24Treatment Strategies for Psychological Disorders
Treatment approaches for psychological disorders fall into three main categories: psychological, biological, and sociocultural. Each approach targets different aspects of mental health, requiring varying levels of education and training.
Psychological therapies focus on modifying emotions, thoughts, and behaviors through talking, interpreting, listening, rewarding, challenging, and modeling. Clinical psychologists, counselors, and social workers commonly practice psychotherapy. Clinical...
