Revised Children's Anxiety and Depression Scale
Also known as: RCADS, RCADS-25
The RCADS is a 47-item (or 25-item brief version) self-report measure that assesses the full spectrum of anxiety disorders and major depression in children and adolescents ages 6–18 years. Developed by Bruce Chorpita in 2000, it provides six subscale scores aligned with DSM-IV diagnostic criteria: Separation Anxiety, Generalized Anxiety, Panic Disorder, Social Phobia, Obsessive-Compulsive Disorder, and Major Depressive Disorder. The RCADS is designed to be both a screening tool and a diagnostic aid.
Key highlights
- Covers full spectrum of DSM-IV anxiety disorders and depression in single measure—more comprehensive than single-disorder scales.
- Subscale cutoff scores have strong diagnostic validity (>85% sensitivity/specificity); can estimate likelihood of meeting DSM-IV criteria without interview.
- Extensive normative data across age (6–18) and gender; T-scores allow comparison to population norms.
- Brief 25-item version (RCADS-25) maintains subscale structure; ideal for time-constrained settings (schools, primary care).
- Strong psychometric properties across diverse samples (US, Australia, Europe); validated in multiple languages.
- Free or low-cost; public domain in many jurisdictions.

When to use it
Primary uses: (1) Screening for DSM-IV anxiety and depressive disorders in school or clinical settings; (2) differentiating anxiety disorders by subtype (e.g., Social Phobia vs. Separation Anxiety) to guide treatment selection; (3) monitoring symptom change during cognitive-behavioral or medication treatment; (4) baseline and outcome measurement in RCTs of interventions for childhood anxiety/depression; (5) identifying comorbid anxiety and depression to detect children at higher relapse risk. Particularly useful in primary care where clinician time is limited; RCADS can prioritize which children need specialist referral.
Strengths & limitations
- Covers full spectrum of DSM-IV anxiety disorders and depression in single measure—more comprehensive than single-disorder scales.
- Subscale cutoff scores have strong diagnostic validity (>85% sensitivity/specificity); can estimate likelihood of meeting DSM-IV criteria without interview.
- Extensive normative data across age (6–18) and gender; T-scores allow comparison to population norms.
- Brief 25-item version (RCADS-25) maintains subscale structure; ideal for time-constrained settings (schools, primary care).
- Strong psychometric properties across diverse samples (US, Australia, Europe); validated in multiple languages.
- Free or low-cost; public domain in many jurisdictions.
- Requires reading comprehension at grade 2–3 level; not suitable for children with significant developmental delay or non-English fluency without adaptation.
- Relies entirely on child self-report; young children (<8 years) may minimize internalizing symptoms due to limited emotion vocabulary.
- OCD subscale (6 items) is brief and may not detect subtle obsessions or complex compulsions; consider adding Yale-Brown OCD Scale if OCD suspected.
- Designed for DSM-IV; does not map perfectly to DSM-5 changes (e.g., Agoraphobia now separate disorder). Subscale interpretation still valid, but cutoffs may need adjustment.
- Does not assess disruptive behavior disorders (ADHD, conduct disorder); comorbid externalizing conditions require separate assessment.

Frequently asked
What is the cutoff score for identifying a child with an anxiety disorder?
There is no single total score cutoff—instead, use subscale cutoffs aligned with DSM-IV diagnoses. For example: Separation Anxiety ≥9 (raw), Generalized Anxiety ≥7, Panic ≥11, Social Phobia ≥14, OCD ≥8, Depression ≥14. These cutoffs indicate ~85% likelihood of meeting diagnostic criteria. Exact cutoffs vary slightly by age and gender; consult the RCADS manual for your child's demographic group.
Can RCADS be used to monitor treatment response?
Yes. Readminister every 3–4 weeks during active treatment. Look for change in raw subscale scores (decrease of ≥3–5 points on a 0–27 subscale = meaningful improvement). Effect sizes (d >0.5) indicate treatment-related change vs. measurement error. Subscale-specific improvement (e.g., Panic decreasing with exposure therapy) confirms mechanism of action.
Does a high RCADS score mean the child has a disorder?
Not necessarily. Elevated scores indicate symptoms are present and frequent, but do not diagnose disorder—duration, onset, functional impairment, and alternative explanations (trauma, medical illness, medication side effect) must be assessed by clinical interview. Use RCADS to determine which disorders to assess in interview, not as sole diagnostic tool.
Is RCADS valid for adolescents with autism spectrum disorder?
RCADS is valid for autistic adolescents with average-to-above-average intelligence and adequate language. However, literal interpretation of items and difficulty identifying internal emotional states (alexithymia) may reduce accuracy. Consider supplementing with parent-report and clinician observation. If autism is suspected, also administer autism-specific measures (AQ, RAADS).
