Introduction Depression is a mood disorder that affects ways that affect individual's emotions, thoughts, behavior, social and occupational functions (Canadian Medical Association CMA, 2013). The Canadian Public Health Administration (PHAC) reported in 2002 that approximately 8% of Canadian adults experience severe depression at some point in their life, which is a major cause of disability in the world over the years . Patient Health Questionnaire - 9 (PHQ - 9) was chosen for this criticism to improve knowledge and understanding of new clinicians' tools and practices in primary care.

Depression: It is measured using the Patient Health Questionnaire (PHQ - 9) score, a nine screening tool that asks about the frequency of symptoms of depression over the past two weeks (5). Response categories of "Do nothing", "Days", "Half day or longer", and "almost every day" were scored in the range of 0 to 3. Summary scores ranged from 0 to 27. This is a fully verified cut point used in the primary care setting (5). Difficulties with depression: People with a PHQ - 9 symptom score of 1 or more are asked. "The reactions are 0 (not difficult at all), 1 (somewhat difficult), 2 (moderately difficult) or 3 (very difficult) In Figure 4 we define 1 as" somewhat difficult " 3 as "moderate or extreme difficulty".

depression. Depression was measured using patient health questionnaire (PHQ-9). According to a comprehensive international diagnostic interview profile, participants were asked to consider two weeks with the highest symptoms. "Consider the longest two weeks when you encountered two problems in the past year Do you often suffer from these problems?" Then we will list PHQ projects In the response of the project , 4 levels of each item from 0 (none) to 3 (almost every day) are used. The higher the score, the higher the frequency of symptoms.
