Reynolds Adolescent Depression Scale-2

William M. Reynolds, Ph.D. © 1987, 1988

The Reynolds Adolescent Depression Scales-2 (RADS-2) is an ideal tool to screen for adolescents with significant depressive symptoms within schools or individual practice settings.

Applications

  • Quickly screens adolescents for serious depression.
  • Well suited for individual or group assessment in clinical or school situations.

Description

The RADS-2 is a brief, 30-item self-report measure that includes subscales which evaluate the current level of an adolescent's depressive symptomatology along four basic dimensions of depression: Dysphoric Mood, Anhedonia/Negative Affect, Negative Self-Evaluation, and Somatic Complaints. Interpretation of these four subscales is based on both the nature of the depression domain and the item content of the subscale.

The RADS-2 standard (T) scores and associated clinical cutoff score provide the clinician or researcher with an indication of the clinical severity of the individual's depressive symptoms (normal, mild, moderate, or severe). Scores are plotted on a Summary/Profile Form, allowing comparison of elevations across subscales. Examining item endorsement levels within elevated subscales can provide further information about the nature of an adolescent's reported symptomatology.

In addition to the four subscale scores, the RADS-2 yields a Depression Total score that represents the overall severity of depressive symptomatology. An empirically derived clinical cutoff score helps to identify adolescents who may be at risk for a depressive disorder or a related disorder. Data demonstrate the ability of this cutoff score to discriminate between adolescents with Major Depressive Disorder and an age- and gender-matched control group. The six RADS-2 critical items alert clinicians that an adolescent (with a Depression Total score below the clinical cutoff) may be experiencing a significant level of depression.

Reliability and Validity

Reliability data (internal consistency, test-retest, and SEMs) are presented for the Depression Total scale and the four subscales. Validity of the RADS-2 was examined from a number of perspectives: content validity, criterion-related validity, construct validity (convergent, discriminant, and factorial), and clinical validity. Reliability and validity studies included a school-based sample of over 9,000 adolescents and a clinical sample of 297 adolescents with DSM-III-RT or DSM-IVT diagnoses who were evaluated in both school and clinical settings. Extensive documentation of reliability and validity evidence for the RADS collected by the author and other researchers over a 20-year period is also presented.

Hand Scoring

RADS-2 materials consist of the Professional Manual; a carbonless, hand-scorable Test Booklet; and the Summary/Profile Form. The RADS-2 items are written at a 3rd-grade level and are worded in the present tense to elicit current symptom status. Symptom content is consistent with a wide range of expert systems and sources (e.g., DSM-IV, ICD-10).
