Screening for Depression

The PHQ-9 is a validated tool to assess the degree of depression present. In general, screening and assessment tools for depression and anxiety contain set questions about symptoms of mental ill health. But unlike most others, this survey was carefully evaluated and validated before being used in clinical practice.

Evidence Appraisal

The PHQ-9 was initially developed by Kroenke et al (2001), as a subset of 9 questions from the full PHQ. It had previously been derived and studied in a cohort of 6,000 patients1. PHQ-9 scores ≥10 were found to be 88% sensitive and also 88% specific for detecting MDD. Criterion validity was also assessed in a sample of 580 patients.

As a result, Arroll et al (2010) validated the PHQ-9 as a screener for Major Depressive Disorder (MDD) in a cohort of 2,642 primary care patients.

Subsequently, the PHQ-9 has also been validated in several additional subpopulations, including in psychiatric patients2, patients with medical comorbidities such as multiple sclerosis and Parkinson’s disease3, pregnant patients4, and in an occupational health setting5.

A meta-analysis of 29 studies including 6,725 patients found similar sensitivity. Notably, they found that 50% of patients screening positive in fact had major depression6.
