Abstract
Recent trends in mental-health care have increased the need for practical depression instruments. The Depression-Arkansas (D-ARK), a brief, economical, multipurpose instrument, has been validated for assessing major depressive disorder (MDD) and depressive-symptom severity. Psychometric properties of the D-ARK were compared with standard depression scales (Beck Depression Inventory and Geriatric Depression Scale) among 294 adult and 193 senior primary-care patients, respectively, and 163 patients enrolled in cognitive-behavioral depression classes. The severity scale displayed adequate internal reliability (coefficient α = .81-.86), high correlation with the BDI-2 (r = .78-.83) and GDS (r = .75), and similar factor structure to the BDI-2, The D-ARK was calibrated against the BDI-2 and GDS, providing familiar severity category cutpoints with the new instrument. This study yields further data supporting the reliability, validity, and practical utility of the D-ARK.
