Patient Health Questionnaire 15

The Patient Health Questionnaire 15 (PHQ-15) is the somatization module of the PHQ. It comprises 15 somatic symptoms that correspond to both the most common physical symptoms in outpatients and the most important DSM-IV criteria for somatization disorder.

The PHQ-15 consists of 13 items from the Somatoform Disorders module and two items from the Depressive Disorders module, which also ask about somatic symptoms (sleep disorders and lack of energy / tiredness).
