Scientific output on validation and adaptation of depression screening instruments in peruvian population.

The aim of the research was to describe the scientific output of psychometric studies on screening instruments for depression in the Peruvian population. We carried out a descriptive study of the scientific literature in Scopus, Web of Science, PubMed and SciELO, with descriptors for depression, psychometric properties, and Peru. After the review process, we included 22 studies. We found validations of screening instruments for older adults, adults, adults with depression, adult women, pregnant women, health professionals, university students, high school students and children. The Patient Health Questionnaire (PHQ-9) was the most widely used instrument. Psychometric studies cover most populations; however, native people and clinical populations remain to be studied. The PHQ-9, due to its characteristics, could be implemented in mental health policies in Peru.
