Music therapy training programmes in the United Kingdom are accredited by the Health and Care Professions Council (HCPC). The HCPC requires registered music therapists to have experience and understanding of the value of therapy for developing insight and self-awareness. In practice, this currently translates into a requirement for personal therapy during training – working therapeutically and confidentially with a suitably qualified and registered therapist for a minimum number of hours – although the amount and type of therapy required varies between course providers. The aim of this study was to explore the perceived value and impact of mandatory personal therapy from the perspectives of trainee and HCPC-registered music therapists. Data were collected through a qualitative survey with open-ended questions exploring participants’ personal therapy experiences. Thirty-nine participants were recruited from across the various music therapy training institutions in the UK at the time of the research and from within the pool of registered music therapists. Thematic analysis was used to develop three themes from the data: “personal therapy is costly, but ultimately beneficial”; “personal therapy provides a supportive space separate from training”; and “personal therapy is part of becoming a music therapist.” We conclude with recommendations about how personal therapy can be most usefully incorporated into training programmes based on our interpretation of the participants’ responses.
