This study assessed the feasibility of a music therapy intervention protocol for adolescents in an Emergency Department Extended Care Unit (EDECU) of the Children’s Hospital of Philadelphia. This theory-based protocol was designed using the theories of resilience and hope. The study (N=14) was implemented in two phases (Phase 1 n=4; Phase 2 n=10). Data was collected using semi-structured interviews with participants, review of EMR notes, descriptive statistics and statistical analyses for stress, Heart Rate Variability. The intervention protocol demonstrated a high degree of feasibility and acceptability. Participants found it engaging, helpful, with minimal burden, and in alignment with their values. Additionally, the protocol was deemed ethical, and participants understood its value. Limited efficacy results revealed statistically significant reductions in stress and improvements in hope. While resilience did not achieve a statistically significant effect, elements such as competence, connection, character, contribution, coping, and control were highlighted in participants' experiences as plausible mediating pathways for its effect. The emphasis of the protocol was on dignity and autonomy as constructs aligned with person-centered approaches to healthcare. The protocol was found to be implementable, with high participant responsiveness and study completion rates. Preliminary evidence indicated that stress reduction and increased hope could be achieved in two sessions. The findings also emphasized choice control and witnessing as essential components for meaningful therapeutic engagement. Additional constructs to explain the feasibility of the protocol included the concept of self-worth promoted by nurturing the participant’s life drive and safely closing the cycle between emotional awareness and self-expression for adolescents experiencing psychiatric emergencies. / Music Therapy
