Depression Screening Tool: PHQ-9 Test for Android

Developer's Description

The Depression Screening Tool: PHQ-9 Test app is based on the current American Psychiatric Associations gold standard in depression testing. The PHQ-9 is one of the most validated tools in the field of mental health and is widely used by physicians and psychiatrists in both diagnosing and monitoring patient response to treatments. The test is based on the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders for major depressive disorder.

Advantages of the PHQ-9:

Shorter than other depression rating scales

Can be administered in person by a clinician, by telephone, or self-administered

Facilitates diagnosis of major depression

Provides assessment of symptom severity

Is well validated and documented in a variety of populations

Can be used in adolescents as young as 12 years of age

Research has shown that certain scores on the PHQ-9 are strongly correlated with a subsequent major depression diagnosis. However, not everyone with an elevated PHQ-9 is certain to have major depression. The PHQ-9 is intended as a tool to assist clinicians with identifying and diagnosing depression but is not a substitute for diagnosis by a trained clinician.
