Abstract
BACKGROUND: Expert-consensus guidelines have been developed for how members of the public should assist a person with a mental health problem or in a mental health crisis. AIMS: This review aimed to examine the range of guidelines that have been developed and how these have been implemented in practice. METHOD: A narrative review was carried out based on a systematic search for literature on the development or implementation of the guidelines. RESULTS: The Delphi method has been used to develop a wide range of guidelines for English-speaking countries, Asian countries and a number of other cultural groups. The primary implementation has been through informing the content of training courses. CONCLUSION: Further work is needed on guidelines for low- and middle-income countries. DECLARATION OF INTEREST: A.F.J. is an unpaid member of the Board of Mental Health First Aid International (trading as Mental Health First Aid Australia), which is a not-for-profit organisation.
