Evidence regarding quality indicators in primary health care is a major need for better mental health management, monitoring and decision-making. In this paper, we compared two methods of retrieving quality indicators for mental health in primary care by means of an umbrella review, that included eight systematic reviews, and of grey literature. From the umbrella review, 48 primary studies that composed the 8 revisions were analyzed. A total of 94 quality indicators for mental health in primary care were found with the umbrella review, while 2000 indicators were found using the grey literature method. Sixty-eight indicators (3.2% from total) were common to both methods. Both methods can be complementary and useful in order to identify quality indicators.
