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.
Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

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.

Drug Dependence01:17

Drug Dependence

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...
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...
Pharmacokinetic–Pharmacodynamic Relationship: Exposure, Response and Effect01:26

Pharmacokinetic–Pharmacodynamic Relationship: Exposure, Response and Effect

The pharmacokinetic-pharmacodynamic (PK-PD) relationship describes the intricate link between drug exposure, efficacy, and toxicity, forming the foundation for optimal dosing regimens. This relationship uses mathematical modeling to characterize drug concentration-effect dynamics, ensuring precise therapeutic outcomes.Exposure represents the pharmacokinetic aspect of the PK-PD relationship, denoting the drug amount that elicits a biological response. It is typically quantified by administered...
Pharmacokinetic–Pharmacodynamic Relationship: Problems01:24

Pharmacokinetic–Pharmacodynamic Relationship: Problems

The empirical approach to drug therapy optimization relies on correlating pharmacological response with administered dosage. Such an approach can be costly, time-consuming, and often yields poor correlation due to variables like formulation factors and drug elimination characteristics. A more precise approach correlates response with plasma drug concentration or the amount of drug in the body, rather than dosage. This is achieved through pharmacokinetic-pharmacodynamic (PK/PD) modeling, which...

Summary

The new ADHD Medication Attitude Scale (AMAS) effectively measures attitudes toward ADHD medication. Positive attitudes and older age predict better medication adherence in individuals with ADHD.

Area of Science:

  • Psychiatry
  • Psychology
  • Clinical Psychology

Background:

  • Medication noncompliance is a significant challenge for individuals with Attention-Deficit/Hyperactivity Disorder (ADHD).
  • Understanding patient attitudes toward medication is crucial for improving treatment adherence.

Purpose of the Study:

  • To introduce the ADHD Medication Attitude Scale (AMAS).
  • To provide initial psychometric analyses and discriminant validity data for the AMAS.
  • To assess the relationship between attitudes toward ADHD medication and self-reported usage.

Main Methods:

  • The AMAS was distributed online via ADHD-focused websites.
  • Data were collected from 356 respondents regarding demographics and 6-month medication usage.
  • Factor analysis was employed to refine the scale and assess its structure.

Main Results:

  • Factor analysis identified two distinct factors: positive and negative attitudes toward medication.
  • The refined 22-item AMAS demonstrated strong reliability (α =.83).
  • Positive attitudes, negative attitudes, and age (≥19 years) independently predicted self-reported medication adherence.

Conclusions:

  • The AMAS is a reliable and valid instrument for evaluating attitudes towards ADHD medication.
  • Assessing attitudes using the AMAS can help predict medication adherence in individuals with ADHD.
