Evaluation of Interactions with Sounds in Improvisational Music Therapy Using Psychological and Psychophysiological Responses

This study examines the impact of interactions with sounds during improvisational music therapy on psychological and psychophysiological indicators. We conducted a sound exchange activity using tone chimes. Improvisational music therapy techniques were employed to initiate empathetic communication. The results indicated that interactions with sounds positively affected the short version of the Profile of Mood States （POMS）, improved interpersonal impression ratings, and increased empathy. Psychophysiological indices also showed activation of psychological adjustment states and sympathetic nervous activity following sound interactions. Furthermore, therapist-led improvisational music therapy interventions demonstrated more remarkable improvements than those led by university student peers in Vigor, as indicated by the POMS and interpersonal impression ratings for empathy, open-mindedness, and trying to fit in. Gaining a clearer understanding of the effects of interactions with sounds on psychological and psychophysiological responses can serve as a foundational element for offering multifaceted support to a diverse range of clients.
