A screening tool designed by the World Health Organization (WHO) to assesses for common mental disorders in primary health care, and/or community settings. SRQ consists of 20 short, Yes/No questions that inquire about the presence of anxiety, depression, and psychosomatic symptoms during the past month. It originally comprised 25 questions, twenty of which assessed neurosis, four assessed psychosis, and one explored convulsions; however, it was later shortened to 20 items (SRQ-20) pertaining exclusively to neurosis. An SRQ-24 exists, which still contains the original 20 questions about neurosis and four questions about psychosis, but it is not as commonly used as the SRQ-20. The maximum total score for SRQ-20 is 20, with a “Yes” response indicating symptom presence, and “No”, the absence of a symptom. The SRQ can be self-administered, but in settings where there are high levels of illiteracy, an interviewer should administer it.
