Abstract

Objective: To provide preliminary evidence for the impact of problem-solving therapy for diabetes (PST-D) in adults with diabetic retinopathy (DR) and diabetes distress.

Research design and methods: In a pilot randomized controlled trial, 40 participants with DR and diabetes distress were allocated to the PST-D or control groups. Diabetes distress (DDS), depressive symptoms (PHQ-9), self-care activities (SDSCA), and HbA1c were assessed at baseline, and 3 and 6-month follow-ups.

Results: At the 6-month follow-up, the PST-D group showed significant improvements relative to the control group, in 'regimen-related distress' (PST-D: -1.3±1.4; control: -0.4±1.1), depressive symptoms (PST-D: -4.3±6.1; control: -0.3±4.6), and HbA1c (PST-D: -1.2%±1.01; control: 0.2%±1.2%) (all p<0.05). In multiple regression analysis, adjusting for baseline values and sociodemographic factors, PST-D was associated with significant improvement in 'regimen-related distress', depressive symptoms, and HbA1c at the 6-month follow-up (p<0.05).

Conclusions: PST-D is a promising intervention for improving psychological outcomes and glycemic control. A fully powered study is required to confirm these findings and examine mechanisms of change in HbA1c.
