Screening adolescents with mental retardation for depression

Area of Science:

• Child and Adolescent Psychiatry
• Developmental Psychology
• Educational Psychology

Background:

• Assessing depression in adolescents with mild intellectual disabilities presents unique challenges.
• Existing screening tools may require adaptation or validation for this population.
• The role of school nurses in identifying mental health concerns is crucial.

Purpose of the Study:

• To evaluate the reliability and validity of the Children's Depression Inventory (CDI) in adolescents with mild intellectual disabilities.
• To determine if the CDI is a suitable self-report screening tool for depression in this demographic.
• To compare CDI self-report scores with observer-based psychopathology ratings.

Main Methods:

• The study included 27 adolescents with mild intellectual disabilities attending metropolitan schools.
• Reliability was assessed using Cronbach's alpha and test-retest correlations.
• Validity was examined by comparing CDI scores with the Reiss Scales for Children's Dual Diagnosis.

Main Results:

• The CDI demonstrated adequate reliability with Cronbach's alpha of 0.79 and test-retest correlation of 0.90.
• Significant negative associations were found between CDI scores and the Reiss Scales for female students.
• Observer reports alone may be insufficient for screening depression in this group.

Conclusions:

• The Children's Depression Inventory is a reliable and valid tool for screening depression in adolescents with mild intellectual disabilities.
• School nurses can effectively utilize the CDI as a self-report screening measure.
• A multi-method approach, including self-report and observer data, is recommended for comprehensive depression screening.
