Film-Based Music Therapy With AI-Generated Verbal Guidance for Anxiety in Young Adults

This study is a single-center, randomized controlled trial designed to investigate the effects of music-based interventions with different types of verbal guidance on anxiety and emotional regulation in young adults.

Eligible university students are recruited and randomly assigned in equal numbers to one of three parallel groups: (1) a music intervention with verbal guidance generated by a large language model and designed to evoke Eastern aesthetic imagery; (2) a standard music therapy condition that includes conventional relaxation-oriented verbal suggestions; and (3) a music-only relaxation condition without verbal guidance. Randomization is conducted using a simple random allocation procedure.

All participants complete baseline assessments prior to the intervention. Each participant then takes part in a single music listening session lasting approximately 25-30 minutes in a quiet classroom setting. During the session, participants are seated comfortably with eyes closed and instructed to listen attentively to the music. Verbal guidance, when present, is delivered by a researcher during the music session.

Primary and secondary outcomes are assessed immediately before and after the intervention. Anxiety is measured using a standardized self-report anxiety scale. Emotional states are assessed using validated measures of positive and negative affect. Heart rate is recorded as an objective physiological indicator of autonomic arousal using a smartphone-based photoplethysmography method.

This study aims to provide empirical evidence on whether culturally adapted verbal guidance, generated by artificial intelligence, can enhance the psychological and physiological effects of music-based relaxation in young adults.
