Psychometric and Clinical Evaluation of the Clinician (VQIDS-C) and Self-Report (VQIDS-SR) Versions of the Very Quick Inventory of Depressive Symptoms.

Purpose: Evaluate the psychometric properties of the 5-item Very Quick Inventory of Depressive Symptomatology self-report and clinician-rated versions (VQIDS-SR/VQIDS-C), compare their relative performance, create crosswalks between their total scores and other accepted depressive symptom ratings, and define clinically relevant depressive symptom severity thresholds and categorical outcomes for both versions.

Patients And Methods: The Sequenced Treatment Alternatives to Relieve Depression trial obtained baseline and exit 17-item Hamilton Rating Scale for Depression (HRSD) and 30-item Inventory of Depressive Symptomatology - Clinician-rated scores, and baseline and visit-wise QIDS-SR and QIDS-C ratings from the first treatment step (citalopram). The VQIDS-C and the VQIDS-SR items (sad mood, self-outlook, involvement, fatigue, psychomotor slowing) (each rated 0-3), extracted from the corresponding 16-item ratings, were selected to best reflect the 6-item HRSD (HRSD) (exclusive of anxiety).

Depression screening and treatment among uninsured populations in Primary Care.

Uninsured populations have poor treatment engagement and are less likely to receive evidence-based interventions for depression. The objective of the current study was to retrospectively examine depression screening, diagnosis, and treatment patterns among uninsured patients in primary care. Study sample included all patients ( = 11,803) seen in nine community-based clinics.
