Self-care tools to treat depressive symptoms in patients with age-related eye disease: a randomized controlled clinical trial.
2017
Background
Depression is very common in people with age-related eye disease. Our goal was to determine if self-care tools plus limited telephone support could reduce depressive symptoms in patients with age-related macular degeneration or diabetic retinopathy.
Design
A single-blind randomized controlled clinical trial was conducted at Maisonneuve-Rosemont Hospital in Montreal, Canada.
Participants
Eighty participants were recruited.
Methods
To be eligible, participants must have had either late stage age-related macular degeneration or diabetic retinopathy, at least mild depressive symptoms, and visual acuity better than 20/200. Half were randomized to the intervention arm and half to delayed intervention/usual care. The intervention consisted of large print written and audio tools incorporating cognitive-behavioral principles plus three 10-minute telephone calls from a lay coach. Eight-week follow-up data were collected by telephone.
Main Outcome Measures
The primary outcome was the 8-week change in depressive symptoms as measured by the Patient Health Questionnaire-9. Secondary outcomes included anxiety, life space and self-efficacy.
Results
The baseline mean logMAR visual acuity was 0.37 (SD = 0.20), and the baseline mean Patient Health Questionnaire-9 score was 9.5 (SD = 3.9) indicating moderate depressive symptoms. After adjusting for baseline imbalances in visual acuity, the intervention reduced depressive symptoms by 2.1 points more than usual care (P = 0.040). The intervention was not associated with the secondary outcomes (P > 0.05).
Conclusions
Self-care tools plus telephone coaching led to a modest improvement in depressive symptoms in patients with age-related eye disease. Additional research on how to maximize their effect is necessary.
