Reliability The reliability of this instrument was exceptional. The PHQ-9 scored a 0.89 Cronbach’s Alpha within the Primary care setting and a Cronbach’s Alpha of 0.86 in the Obstetrics and Gynecology setting. To test reliability a test-retest was done using follow up phone interviews with a Mental Health professional in a trial of 580 patients. This test was performed within 48 hours of the original PHQ-9. The Cronbach’s Aplha was 0.84 for the test-retest. The means score for the clinic samples was 5.08 and 5.03 for the telephone interviews. The reliability appears to be great for this instrument and has similar results in different settings.

Many times when I ask a resident with dementia this question they begin to get upset and tearful. It causes them to feel emotions in regards to missing their families and it causes the interview to take longer because the social worker needs to be empathetic to the patient.
