Brief summary
This three-year award will pilot-test an innovative intervention, Resilient, Empowered, Active Living with Diabetes (REAL), targeting underserved minority young adults with poorly-controlled diabetes. The individually tailored, community-based intervention merges findings of an in-depth needs assessment, principles of an evidence-based occupational therapy intervention (Lifestyle Redesign®) and evidence-based diabetes self-management strategies. A proof-of-concept study demonstrated that REAL is feasible to implement, acceptable to young adults with type 1 diabetes and type 2 diabetes, and has potential to produce positive changes in diabetes self-care and glycemic control. The study will randomize 80 young adults with diabetes to receive either the six-month REAL intervention or an attention control condition. Blinded data collectors will assess glycemic control, diabetes self-care behaviors and quality of life outcomes, as well as potential intervention mediators, before and after the six-month intervention. It is anticipated that findings from this pilot study will be used to inform a large-scale randomized controlled trial of the REAL intervention. The study's specific aims and hypotheses are as follows: Aim 1. Determine the intervention's efficacy for the primary outcomes: glycemic control and diabetes self-care. Hypothesis: At 6 months (immediately following the intervention), intervention group participants will demonstrate improvements in A1C and diabetes self-care as compared to control group participants. Aim 2. Conduct exploratory analyses of the intervention's impact on secondary outcomes and potential mediating mechanisms (to inform power estimates for a large-scale RCT). Hypothesis 1: At 6 months, intervention group participants will demonstrate improvements in secondary outcomes: diabetes-related stress and quality of life, depression, and life satisfaction as compared to control group participants. Hypothesis 2: At 6 months, intervention group participants will demonstrate improvements in potential mediators of the intervention: habit strength, problem solving, activity participation, self-efficacy and diabetes knowledge as compared to baseline. Aim 3. Conduct a process evaluation utilizing mixed methods to evaluate and refine intervention delivery (e.g. treatment fidelity, patient satisfaction) and study procedures (e.g. recruitment, retention, testing protocol).
Interventions
BEHAVIORALResilient, Empowered, Active Living with Diabetes
Individualized lifestyle intervention incorporating the following topics: Diabetes knowledge; access to healthcare; communication with healthcare providers; incorporation of diabetes self-care tasks within daily habits and routines; social support; and emotional well-being. Participants receive a total of 10-16 hours of intervention by a licensed occupational therapist with training in diabetes education, motivational interviewing and the REAL Diabetes intervention protocol.
BEHAVIORALInformation Control
Participants will receive a packet of informational materials about diabetes, and receive periodic follow-up phone calls to match for attention dose. The packet of materials will be delivered in an initial home visit. Follow-up phone calls will occur at approximately two week intervals to inquire whether participants have reviewed specific sections of the intervention materials, and clarify information included in the packet.
