Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

549
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.
Understanding the concepts of physical dependence,...

Mechanistic Models: Compartment Models in Individual and Population Analysis

335
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Drug Abuse and Addiction: Pharmacological Phenomena

1.5K
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...

Drug Dependence

1.9K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Cross-Sectional Research01:50

Cross-Sectional Research

12.9K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Cognitive Development During Adolescence01:18

Cognitive Development During Adolescence

879
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

Area of Science:

  • Adolescent Health
  • Substance Use Research
  • Developmental Psychology

Background:

  • Adolescent multiple substance use presents significant health risks.
  • Understanding patterns and predictors of adolescent substance use is crucial for prevention.

Purpose of the Study:

  • To investigate patterns of multiple substance use among young adolescents.
  • To identify multilevel predictors associated with these substance use patterns.

Main Methods:

  • Longitudinal study of 2490 German students (mean age 13.32).
  • Multilevel latent class analysis applied to substance use data (cigarettes, alcohol).
  • Baseline predictors included demographics, peer/parental substance use, and school characteristics.

Main Results:

  • Three distinct classes identified: non-users (61.9%), experimenters (29.0%), and multiusers (9.1%).
  • Experimental use predicted by age, paternal drinking, and school type.
  • Multiusage predicted by peer substance use, maternal drinking, bullying, age, and school type.

Conclusions:

  • Prevention strategies should focus on social influence and behavioral interventions.
  • Schools without a college-preparatory track require targeted interventions for adolescent substance use.
