Objectives: An increasing number of research studies support the benefits of providing music therapy in addition to standard treatment for people who have mental disorders. The objective of this paper was to review and summarise recent research findings in relation to this work.

Method: A review of music therapy studies published since 1994 was undertaken. Criteria for including papers were that they a) were published in English in an indexed, peer-reviewed journal, and b) were conducted as a randomised controlled trial (RCT) or a controlled trial (CT), or c) provided a meta-analysis of existing studies. The large number of papers pertaining to music therapy for older adults who have mental disorders, including Alzheimer's disease and other types of dementia was not included.

Results: The findings support a role for music therapy as a structured interaction that patients are able to use to participate successfully, manage some of their symptoms, and express feelings relating to their experiences. Music therapy is demonstrated to be a beneficial intervention for people who have enduring mental illness. Music therapy invites and encourages participation from people of lower functioning levels and employs a non-verbal medium with which people have prior positive associations and in most cases have lifelong experience of using music for self-expression and pleasure. Additionally, the available peer reviewed literature supports the proposition that clinical outcomes are available through the use of music therapy intervention in conjunction with standard, well-established treatment methods.

Conclusions: Music therapy is beneficial for patients receiving care for mental disorders and establishing this therapy within mental health service provision should be considered.
