Insights

A new Attention Deficit Hyperactivity Disorder scale was developed and validated for children in Nepal. This culturally adapted tool provides a reliable method for diagnosing ADHD in the Nepalese population.

Area of Science:

  • Child and Adolescent Psychiatry
  • Psychometrics
  • Cultural Adaptation of Diagnostic Tools

Background:

  • Lack of culturally relevant diagnostic tools for Attention Deficit Hyperactivity Disorder (ADHD) in Nepal.
  • Need for a validated ADHD scale specific to Nepalese children and language.

Purpose of the Study:

  • To develop and validate a culturally appropriate ADHD diagnostic scale for children in Nepal.
  • To address the unmet need for reliable ADHD assessment tools in the Nepalese context.

Main Methods:

  • Mixed-methods study with 840 participants (ADHD, Anxiety, General Population).
  • Scale development involved item generation, pilot testing, and psychometric evaluation using established instruments (K-SADS-PL, CASI-5).
  • Statistical analyses included dimensionality, reliability (Cronbach's alpha > 0.91), validity, and norm calculation for standardization.

Main Results:

  • A 21-item ADHD scale with three sub-scales: Inattention, Impulsivity, and Hyperactivity.
  • Demonstrated strong convergent and discriminant validity.
  • Established a cut-off score of 38.5 for diagnosing ADHD.

Conclusions:

  • A valid and reliable ADHD diagnostic scale has been successfully developed for the Nepalese population.
  • The scale is tailored to Nepalese culture and language, facilitating accurate ADHD diagnosis.
  • This contributes a crucial tool for mental health professionals in Nepal.

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....

Diagnostic and Statistical Manual of Mental Disorders (DSM)

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

pH Scale02:41

pH Scale

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Data Validation01:15

Data Validation

Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:
