Brief Summary

Pt. 1 Diabetic retinopathy is a common eye condition among diabetic adults and can lead to severe vision impairment and even blindness. African Americans are more likely to have vision loss from diabetic retinopathy due to a variety of factors, including cultural barriers to care. The investigators aim to increase the rates of eye exams in diabetic African American adults by providing culturally relevant home-based interventions. These interventions will increase the knowledge about diabetes and the eyes and the awareness of ocular risks due to diabetes. 206 African American adults, over the age of 65, with diabetes will be recruited from primary care clinics at Thomas Jefferson and Temple University. Eligible patients who consent to participate will have baseline information taken about medical and ocular history, understanding of diabetes and a hemoglobin A1C level obtained. The subjects will then be randomized to one of two treatment conditions: Behavioral Activation or Supportive Therapy, each of which will be delivered over 4 sessions. Behavioral Activation will consist of educational materials, referral assistance for eye clinics, and addressing patient specific barriers to care. Supportive Therapy will consist of supportive but non-directional interaction with the patient exploring the impact of aging and diabetes on the patient's life. The investigators hypothesize that more patients who receive Behavioral Activation will have a dilated fundus exam (the primary outcome variable), understand the risks of diabetic complications and feel less depression then subjects who receive Supportive Therapy.

Outcome Measures

Primary Outcomes (1)

  • Pt. 1 Dilated Fundus Exam (DFE)

    At the 6-month follow-up assessment, patients will be asked if they got a dilated fundus exam since the baseline assessment. If a DFE is self-reported, it will be confirmed by ophthalmology chart review

    6-month follow-up assessment

Secondary Outcomes (4)

  • Pt. 1 Risk perceptions of diabetes

    6-month follow up assessment

  • Pt. 1 Diabetes self-care behaviors

    6-month follow up assessment

  • Pt. 1 Depressive Symptoms

    6-month follow up assessment

  • Pt. 2 Appointment Adherence Characteristics

    Dependent on Diagnosis

Other Outcomes (1)

  • Pt. 2 Cost-effectiveness

    Conclusion of Study

Study Arms (2)

Pt. 1 Behavioral Activation

EXPERIMENTAL

Behavioral Activation (BA) is a behavioral technique to help people overcome avoidant tendencies through goal setting, activity scheduling, and graded task assignment. The key component of BA involves developing an "Action Plan", and having the subject document each step of the plan as he or she implements it, reinforcing the steps towards goal attainment. "Action Plans" are easily applied to diabetes self-care tasks because the latter lend themselves to documentation of simple, step-by-step plans. In this study, a Community Health Educator (CHE) - interventionist will schedule and deliver four 45-60 minute in-home BA sessions within 3 months of randomization (i.e., one session every 2-3 weeks).

Behavioral: Behavioral Activation

Pt. 1 Supportive Therapy

PLACEBO COMPARATOR

The purpose of Supportive Therapy (ST) is to explore the impact of aging and diabetes on the subject's life. In contrast to the BA intervention, the interventionist does not discuss the importance of dilated eye exams. In subsequent sessions, ST facilitates and deepens knowledge about the subject's life situation in relation to his or her health and other life difficulties. The ST therapist encourages this process and creates an accepting, nondirective, and supportive opportunity for discussion.
