Patient Health Questionnaire-9 (PHQ-9)
The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and measuring the severity of depression.
This easy to use patient questionnaire is self-administered using PTI Apps. The PHQ-9 is in the depression screening module, incorporating DSM-IV criteria to screen for major depressive symptoms.
The PHQ-9 has been validated for use in primary care and rates the frequency of the symptoms which affect the severity index scoring. The ninth question screens for the presence and duration of suicidal ideation.
This assessment is used to monitor the severity of depression and response to treatment. And it can be used to make a tentative diagnosis of depression in at-risk populations – eg, those with coronary heart disease or after stroke.
The PHQ-9 can also be administered repeatedly to reflect the improvement or worsening of depression
PTI App administration of the screen is quick and user-friendly, improving the recognition rate of depression and anxiety and facilitating diagnosis and treatment.
