An exploratory factor analysis of the children's depression rating scale-revised

Area of Science:

• Child and Adolescent Psychiatry
• Psychometric Evaluation
• Mental Health Research

Background:

• The Children's Depression Rating Scale-Revised (CDRS-R) is a widely used measure for assessing depression in pediatric populations.
• Understanding the underlying factor structure of the CDRS-R is crucial for accurate diagnosis and treatment planning.
• Previous research has explored the factor structure of the CDRS-R, but further investigation in diverse clinical samples is warranted.

Purpose of the Study:

• To investigate the factor structure of the Children's Depression Rating Scale-Revised (CDRS-R) in a clinical sample of 314 children and adolescents.
• To identify distinct dimensions of depression as measured by the CDRS-R.
• To examine age and gender differences in the identified depression factors.

Main Methods:

• Exploratory factor analysis was conducted on data from 314 children and adolescents.
• A maximum likelihood method with Promax rotation was employed to determine the factor structure.
• Statistical analyses were performed to evaluate age and gender differences on factor scores.

Main Results:

• The analysis yielded a five-factor structure for the CDRS-R: observed depressive mood, anhedonia, morbid thoughts, somatic symptoms, and reported depressive mood.
• Adolescents exhibited more severe observed depressive mood, anhedonia, and somatic symptoms compared to younger children, after controlling for gender.
• Girls reported higher levels of depressive mood than boys, after controlling for age group.

Conclusions:

• The CDRS-R demonstrates a robust five-factor structure in a clinical sample of children and adolescents.
• Specific depressive symptom dimensions are differentially associated with age and gender, informing targeted interventions.
• These findings contribute to a nuanced understanding of pediatric depression assessment using the CDRS-R.
