Because many people facing the end of life often request spiritual/religious music, Wlodarczyk (41) investigated the effect of music therapy on the spirituality of people in an in-patient hospice unit. Participants (n = 10) were adults newly admitted to the in-patient hospice house; they were able to complete a questionnaire and respond verbally, and to consent to participate in the study. Diagnosis, age, gender and religious preference were not controlled for in this study. Participants served as their own control in an ABAB research design, where session A consisted of cognitive-behavioral music therapy (30 min) and session B consisted of a non-music visit (30 min). The design was counterbalanced (BABA) for half of the participants to control for order effect. Spirituality was measured using the 18-item Spiritual Well-Being Scale (SWBS) and was completed by participants following each condition. Statistical analyses indicated a significant increase in scores on the SWBS on the days in which music therapy was provided. The study supports the use of music therapy to increase spiritual well-being for the terminally ill.
