Classifying child and adolescent psychiatric disorder by problem checklists and standardized interviews

Area of Science:

• Child and Adolescent Psychiatry
• Psychometrics
• Epidemiological Research

Background:

• Standardized diagnostic interviews are the current gold standard for assessing child and adolescent psychiatric disorders.
• However, interviews can be time-consuming, costly, and burdensome for participants and researchers.
• Self-completed problem checklists offer a potentially more efficient alternative.

Purpose of the Study:

• To discuss the need for research on the psychometric adequacy of self-completed problem checklists.
• To present theoretical arguments for the reliability and validity of checklists compared to interviews.
• To review empirical evidence and propose checklists as a viable assessment tool.

Main Methods:

• Theoretical arguments based on psychometric principles.
• Review of existing literature comparing checklists and interviews.
• Discussion of reliability (test-retest) and validity (construct) metrics.

Main Results:

• Checklists have the potential to achieve comparable reliability and validity to diagnostic interviews.
• Modest test-retest reliability (kappa 0.40-0.60) is achievable with checklists using cut-points.
• Past studies showed no construct validity differences, despite partial overlap in classifications.

Conclusions:

• Self-completed checklists can be a reliable and valid method for classifying child and adolescent psychiatric disorders.
• Demonstrating this would offer a simple, flexible, and cost-effective assessment approach.
• This could significantly reduce the burden and cost of psychiatric assessments in research and clinical settings.
