Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
Borderline Personality Disorder01:25

Borderline Personality Disorder

Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

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...
Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...
Personality Disorders: Dependent and Obsessive-Compulsive01:24

Personality Disorders: Dependent and Obsessive-Compulsive

Dependent personality disorder and obsessive-compulsive personality disorder are two separate psychological conditions that influence behavior, relationships, and overall life functioning. Though both involve maladaptive behaviors, their core characteristics and motivations differ significantly.
 Dependent Personality Disorder
Dependent personality disorder is characterized by an excessive reliance on others to manage various aspects of life. Individuals with this disorder often struggle with...

Summary

Individuals with Internet addiction exhibit high trait impulsivity, similar to those with pathological gambling. This suggests Internet addiction may be an impulse control disorder, with impulsivity indicating vulnerability.

Area of Science:

  • Psychiatry
  • Behavioral Science
  • Neuroscience

Background:

  • Internet addiction is increasingly recognized as a behavioral disorder.
  • Poor impulse control is a potential underlying factor in addictive behaviors.
  • Comparing Internet addiction to established impulse control disorders like pathological gambling can elucidate shared mechanisms.

Purpose of the Study:

  • To compare trait impulsivity levels in individuals with Internet addiction versus pathological gambling.
  • To investigate the relationship between the severity of Internet addiction and trait impulsivity.
  • To determine if trait impulsivity is a vulnerability marker for Internet addiction.

Main Methods:

  • A comparative study involving 27 male patients diagnosed with Internet addiction, 27 with pathological gambling, and 27 healthy male controls.
  • Assessment of trait impulsivity using the Barratt Impulsiveness Scale-11 (BIS-11).
  • Measurement of Internet addiction severity with Young's Internet Addiction Test (YIAT) and pathological gambling severity with the South Oaks Gambling Screen (SOGS).
  • Inclusion of Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) to assess comorbid psychological distress.

Main Results:

  • Patients with Internet addiction demonstrated significantly higher levels of trait impulsivity compared to healthy controls.
  • Trait impulsivity levels in Internet addiction patients were comparable to those with pathological gambling.
  • A positive correlation was observed between the severity of Internet addiction and trait impulsivity.

Conclusions:

  • Internet addiction shares core features with impulse control disorders, particularly elevated trait impulsivity.
  • Trait impulsivity may serve as a significant marker for vulnerability to developing Internet addiction.
  • These findings support conceptualizing Internet addiction as an impulse control disorder.
