OBJECTIVE: To determine the predictive validity of the Patient Health
Questionnaire-9 (PHQ-9) when screening for symptoms of depression after traumatic
brain injury. DESIGN: Retrospective analysis of data collected as part of routine
clinical outpatient care over a period of 30 months.
SETTING: Regional
rehabilitation facility. PARTICIPANTS: Persons (N=137) with mild to severe
traumatic brain injury who were referred for neuropsychological evaluation within
1 to 12 months. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: PHQ-9 and
Minnesota Multiphasic Personality Inventory-2-Restructured Form. RESULTS: PHQ-9
scores >/=10 had a sensitivity of 91.7 and a specificity of 60.2 for predicting a
diagnosis of major depression. Correlations between scores of PHQ-9 and Minnesota
Multiphasic Personality Inventory-2-Restructured Form Demoralization (.64) and
Low Positive Emotions (.48) scales ranged from large to medium. Premorbid
outpatient psychiatric treatment was the most consistent predictor of PHQ-9
elevations as well as final diagnoses of major depression. CONCLUSIONS: The PHQ-9
has adequate clinical utility as a screening instrument for depression in
outpatients with traumatic brain injury. Elevations on this instrument cannot,
however, be automatically attributed to neuropathology, especially not in the
context of premorbid psychiatric dysfunction. Clinicians should conduct more
thorough follow-up assessment in those with highly elevated PHQ-9 scores.
