Stop Depression is a mobile application that allows people to check if they have symptoms of depression. If so, it can advise the user top seek for professional help.
This app was developed in cooperation with psychologists. It uses Patient Health Questionnaire - 9 (PHQ-9) and Patient Health Questionnaire - 915 (PHQ-15) tests to measure the risks and symptoms of depression. It also includes first aid information.
The copyright for the PHQ-9 was formerly held with Pfizer, who provided the educational grant for Drs Spitzer, Williams and Kroenke who originally designed it. This is no longer the case and no permission is required to reproduce, translate, display or distribute the PHQ-9.
NOTE, this app is helpful in assessing the degree of depression, but is not intended to give diagnosis. If you think this is necessary, please contact a professional.
