Music therapy is the clinical and evidence-based use of music interventions to accomplish individualized goals within a therapeutic relationship by a credentialed professional who has completed an approved music therapy program. Music therapy is an established health profession in which music is used within a therapeutic relationship to address physical, emotional, cognitive, and social needs of individuals (American Music Therapy Association [AMTA], 2013, para 1 and 2).

During the educational music therapy intervention, member(s) of the Adult Sickle Cell Disease team will share with the patients the medical information pertinent to the appointment via a prerecorded video. The Music Therapist will then engage the patients in a music therapy intervention designed to teach and reinforce the skills and knowledge presented. These music therapy interventions may include but are not limited to original songs/rap/instrumental playing, vocal and/or instrumental improvisation, patient-contributed lyrics, mnemonics, and stress and pain reducing strategies. The music therapy interventions will be tailored to best convey the educational message.

Self-efficacy is the conviction that one can successfully execute the behavior required to produce the outcome.

(Bandura, 1997, p. 193). The SCSES is a nine-item Likert scale originally developed for adults with sickle cell disease (Edwards, Telfair, Cecil, & Lenoci, 2000) and revised in a follow up study by Clay and Telfair (2007) for adolescents using a sample of 131 individuals age 11-19.

Patient trust is the optimistic acceptance of a vulnerable situation in which the patient believes the health-care provider will take care of the patient's interests (Dugan, Trachtenberg, & Hall, 2005).The Wake Forest Trust in the Medical Profession Scale is a five-item scale in which respondents express their level of agreement with the following statements: 1) Sometimes doctors care more about what is convenient for them than about their patients' medical needs (reverse coded); 2) Doctors are extremely thorough and careful; 3) You completely trust doctors' decisions about which medical treatments are best; 4) A doctor would never mislead you about anything; 5) All in all, you trust your doctor completely. Responses are summed and scores are on a 5-25 scale, with higher values indicating greater trust.

Sickle Cell Disease knowledge will be measured using the Seidman Sickle Cell Knowledge Quiz developed specifically for this study. The Seidman Sickle Cell Knowledge Quiz is adapted from questions from the Sickle Cell Disease Knowledge Test (Kaslow et al., 2000) and How Much Do I Know About Sickle Cell Disease (Baskin, Collins, Kaslow, & Hsu, 2002).

Adherence is the extent to which a person's behavior coincides with medical or prescribed health advice (Julius, 2009).Adherence will be measured regularly throughout the study via medical record review. In order to assess adherence, the following data will be obtained from the medical record on each patient throughout the study period: 1) Total scheduled clinic visits with Adult Sickle Cell Disease Clinic, 2) Number of missed clinic visits to Adult Sickle Cell Disease Clinic due to no show, cancellation, or rescheduling
