Individuals receiving hospice care at the end of life have a unique set of needs, requiring interdisciplinary assessment and treatment to meet their multidimensional circumstances and create a supportive and comfortable experience. Music therapy is often an integral component of hospice care utilized to treat the whole person. While there are published music therapy assessment tools for use with the hospice population, there is no assessment tool specifically aimed at understanding the role of music preference in the context of the hospice patient’s multidimensional musical ecosystem identity. The purpose of this thesis was to create an assessment tool to understand and document the individualized connections between a hospice patient’s familiar and preferred music and their musical identity, in order to increase cultural awareness and to utilize music selection with purpose while supporting and empowering the patient. The proposed music preference assessment tool utilizes an ecomap structure and combines theories and philosophies from the fields of music therapy and social work. The needs of the hospice population are identified and music therapy is discussed as a treatment modality in hospice. Existing music therapy and social work assessments are identified and examined and elements of each are utilized in the creation of the proposed music preference assessment tool. A template and example assessment tool are provided with considerations for clinical implications and uses.
