Professional popular musicians are at increased risk of psychological distress, substance use problems, and suicide, yet little evidence is available on effective psychotherapeutic practices to address these issues. This scoping review aims to understand how professional popular musicians perceive, engage with, and respond to mental health interventions. Four databases were searched, garnering a total of 310 articles. Of these, six met inclusion criteria. Four thematic categories were explored: (1) amenability of professional popular musicians to particular therapeutic approaches; (2) attribution of treatment outcomes to tailored approaches; (3) professional popular musicians’ perceived barriers to treatment; and (4) recommendations for treatment approaches. The scoping review supports the importance of considering the characteristics of professional popular musicians as a distinct group with unique well-being needs, challenges, and strengths. There is a clear preference for tailored, affordable, and accessible approaches that consider the uniquities of musicianship and the need to explore the role of nonclinical support, such as friends, family, and industry peers.
