ABSTRACT
BACKGROUND: The majority of individuals with major depressive disorder are diagnosed and treated in the primary-care setting. A quantifiable critical objective in the management of depression is to achieve and sustain full symptomatic remission. The HAMD-7 is a depression metric validated in both tertiary and primary-care settings. METHODS: Herein, we further characterise the psychometric properties of the HAMD-7 in depressed patients treated in primary-care settings. Several cut-scores were evaluated for maximum agreement; diagnostic efficacy statistics with the original HAMD-7 items were also evaluated. We compared performance of the HAMD-7 in primary care to a previously characterised tertiary sample. RESULTS: The depressive symptoms most frequently endorsed (>or=70%) and most sensitive to change during antidepressant treatment in depressed primary-care patients were depressed mood, guilt, work and activities, psychic and somatic anxiety and fatigue. LIMITATIONS: This is a post hoc analysis of a primary-care database; assumptions regarding the definition of symptomatic remission in depression affect interpretation. CONCLUSION: Measurement-based care with the HAMD-7 quantifies the severity of commonly reported depressive items and their responsivity to treatment. The HAMD-7, inclusive of the suicide item, is capable of tracking symptom progress, with a validated remission cut-score.
