Patient Health Questionnaire
- Measure Overview
- Measure Details
A 16-item self-report questionnaire designed to "diagnose" mental disorders in primary care. Spitzer et al. 1999) reported that the diagnostic validity of PHQ is comparable to the original clinician-administered PRIME-MD (Primary Care Evaluation of Mental Disorders, Miranda J, Hohmann AA, Attkisson CC, Larson DB, 1994). PHQ assesses 8 mental disorders, including major depressive disorder, panic disorder, other anxiety disorder, bulimia nervosa, other depressive disorder, probably alcohol abuse or dependence, somatoform disorder, and binge eating disorder. There are several variations of the PHQ: PHQ-9 (Kroenke K, Spitzer RL, Williams JB, 2001) is for depression severity. PHQ-15 (Kroenke K, Spitzer RL, Williams JB, 2002) is for severity of somatic symptoms. PHQ-2 (Kroenke K, Spitzer RL, Williams JB, 2003) is a depression screener. PHQ-8 (Kroenke K, Strine TW, Spitzer RL, et al. 2009) is a depression measure for population-based studies. PHQ-4 (Kroenke K, Spitzer RL, Williams JB, Löwe B., 2009) is for screening of anxiety and depression. PHQ-A (Johnson JG, Harris ES, Spitzer RL, Williams JB, 2002) is for adolescents.
