Non-specific psychological distress — symptoms of anxiety and depression — over the last four weeks. It was built for screening in the general population and national health surveys, not to diagnose any specific disorder.
This questionnaire is a screening tool, not a diagnosis; only a qualified mental-health professional can diagnose. If you feel severe distress or have thoughts of harming yourself, call Iran's social emergency line 123 or the counselling line 1480 now, or go to the nearest medical centre.
