Effective screening can help clinicians better coordinate a patient’s mental and physical care and may lead to earlier connection to a mental health professional.1

Patient Health Questionnaire (PHQ-9)
A standardized tool such as the PHQ-9 is often used to screen patients for depressive symptoms in primary care settings. The PHQ-9 is a multipurpose instrument used for screening, measuring, and monitoring the severity of depression.2
Compositive International Diagnostic Interview (CIDI) 3.0
The clinician-administered CIDI 3.0 may also improve the efficiency in detecting bipolar disorder.3

General Anxiety Disorder 7 (GAD-7)
Anxiety disorder may be routinely assessed alongside mood symptoms in patients with bipolar disorder.4 The GAD-7 is a self-rated questionnaire used to screen for general anxiety disorder and assess symptom severity.5

An important note: This toolkit does not include a comprehensive set of all available screeners. Screeners and questionnaires are not for diagnostic use, nor are they a replacement for your professional medical advice and judgment. For measures that are self-reported by the patient, clinicians should verify responses as part of the clinical interview.
