The Child and Adolescent Psychiatric Assessment (CAPA)

Area of Science:

• Child and Adolescent Psychiatry
• Psychiatric Diagnostics
• Clinical Assessment Tools

Background:

• Significant advancements in structured psychiatric interviews over 20 years.
• Identified weaknesses in defining child/adolescent psychiatric symptoms and impairments.
• Existing child psychiatric interviews often limited to single diagnostic systems (e.g., DSM-III, ICD-9), hindering comparisons.

Purpose of the Study:

• To address limitations in child and adolescent psychiatric assessment.
• To introduce the Child and Adolescent Psychiatric Assessment (CAPA) as a solution.
• To outline principles for improving standardization, reliability, and meaningfulness of symptom and diagnostic ratings.

Main Methods:

• Development of an interviewer-based diagnostic interview.
• Creation of versions for both children and their parents.
• Focus on symptoms occurring within the preceding 3-month period.
• Adaptation for both clinical and epidemiological research settings.

Main Results:

• The CAPA aims to standardize and improve the reliability of psychiatric symptom and impairment ratings in youth.
• Provides a more comprehensive and flexible diagnostic tool compared to previous single-system interviews.
• Facilitates more meaningful and comparable diagnostic assessments in child psychiatry.

Conclusions:

• The Child and Adolescent Psychiatric Assessment (CAPA) offers a standardized approach to diagnosing psychiatric disorders in children and adolescents.
• CAPA enhances the quality of diagnostic information for both clinical practice and research.
• The interview's design supports improved reliability and cross-diagnostic comparability in child psychiatric evaluations.
