Bullying

8.4K
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

167
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,...

Drug Dependence01:17

Drug Dependence

1.0K
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...

Combined Effects of Drugs: Synergism

3.9K
Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

Drug Discovery: Overview

7.9K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Structure-Activity Relationships and Drug Design

718
Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

Area of Science:

  • Public Health
  • Adolescent Psychology
  • Educational Interventions

Background:

  • Adolescent substance use is a major public health concern, particularly during early-to-mid adolescence.
  • Deviant peer affiliation is a key factor in adolescent substance use.
  • Current school-based prevention programs show limited effectiveness.

Purpose of the Study:

  • To evaluate cooperative learning (CL) with technology for reducing deviant peer affiliation and substance use in adolescents.
  • To assess the impact of CL on alcohol, tobacco, and marijuana use.
  • To determine if dosage of CL lessons influences outcomes.

Main Methods:

  • A one-year cluster randomized trial involving 12 middle and high schools (N=813 students).
  • Implementation of cooperative learning (CL) supported by specialized technology.
  • Multi-level modeling to analyze intervention effects on deviant peer affiliation and substance use.

Main Results:

  • Significant intervention effects were found for reduced deviant peer affiliation and alcohol use.
  • Tobacco use decreased significantly among non-White students; marijuana use effects were marginally significant.
  • A significant dosage effect was observed for all outcomes, indicating lesson impact.

Conclusions:

  • Cooperative learning (CL) with technology is a viable universal prevention strategy for adolescent substance use.
  • The intervention effectively reduced deviant peer affiliation and alcohol consumption.
  • Future research should explore combining CL with existing evidence-based prevention curricula.
