Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

556
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Attention-Deficit/Hyperactivity Disorder

1.4K
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....

Drug Abuse and Addiction: Pharmacological Phenomena

1.6K
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...

Area of Science:

  • Psychology
  • Neuroscience
  • Public Health

Background:

  • Extensive literature documents the link between substance use and impulsivity.
  • Recent research shifts focus from trait impulsivity to its moment-to-moment expression in daily life.
  • Existing reviews primarily address trait-level impulsivity, limiting understanding of real-world contexts.

Purpose of the Study:

  • To conduct a comprehensive meta-analysis synthesizing findings on everyday impulsivity and substance use.
  • To quantify the strength of the association between everyday impulsivity and alcohol, cannabis, and tobacco use.
  • To identify key moderators influencing this relationship, including substance type, sample characteristics, and methodology.

Main Methods:

  • Systematic search of major databases (PsycINFO, PubMed, Web of Science) for published and unpublished studies.
  • Inclusion of studies reporting associations between everyday impulsivity and alcohol, cannabis, or tobacco use.
  • Application of random-effects models for pooled effect size estimation and subgroup/meta-regression analyses for moderator testing.

Main Results:

  • (Pending completion of the meta-analysis) This section will present the synthesized findings on the association between everyday impulsivity and substance use.
  • (Pending completion of the meta-analysis) This section will detail the quantified strength of the relationship across different substances and populations.
  • (Pending completion of the meta-analysis) This section will report on identified moderators affecting the impulsivity-substance use link.

Conclusions:

  • This meta-analysis will provide a comprehensive estimate of the association between everyday impulsivity and the use of alcohol, cannabis, and tobacco.
  • Findings will enhance understanding of how fluctuating impulsivity influences substance use in real-world settings.
  • Results will inform targeted interventions and prevention strategies for substance use disorders by highlighting the role of everyday impulsivity.
