Homeless People in French-speaking Switzerland and Integrative Medicine: A Pilot Intervention in Music Therapy

The goal of this observational study is to evaluate the feasibility to develop and implement a music therapy intervention among homeless individuals in French-speaking Switzerland. The main questions it aims to answer are: * Are the music therapy sessions acceptable? * Are the music therapy sessions feasible? * Are the chosen effectiveness primary outcomes appropriate for future larger studies (i.e., health-related quality of life and psychological stress)? Participants will take part in six sub-group (of 6 participants) 2-hours music therapy sessions over 6 weeks. The sessions will be conducted by a certified music therapist and will offer sensory workshops of immersive musical listening, digital and acoustic music creation and shared improvised music. The music therapy sessions aim to create a space for sound and relaxation; promote the emergence of creativity and improvements in social skills and self-esteem through the co-construction of a privileged space for musical interaction.
