This project constitutes a systematic investigation of Guided Imagery and Music (GIM) as a therapeutic method for working with persons who have depression. GIM is a music-centered integrative therapeutic method in which specially designed music programs facilitate client imagery experiences in non-ordinary states of consciousness. With the support of the therapist, these experiences provide transformative spaces for growth. Prior research has shown that a series of GIM sessions can lead to positive mood-related outcomes for persons with a variety of physical and mental health concerns. In addition, case studies have documented GIM as a therapeutic method that can be used with persons who have depression. This research project examines GIM as a therapeutic approach specifically for persons who have depression.
