What is the RADS-2?
The Reynolds Adolescent Depression Scale-2 (RADS-2) is an ideal tool to screen for adolescents with significant depressive symptoms within schools or individual practice settings. 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.
Why Should I Use the RADS-2?
RELIABLE AND VALID. Reliability data (internal consistency, test-retest, and SEMs) are presented for the Depression Total scale and the four subscales in the technical manual. 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 in the manual.
CLINICAL RELEVANCE. 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.
OVERALL SCORE. 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.
