Dissatisfaction with performance of valued activities predicts depression in age-related macular degeneration.

OBJECTIVE: To determine whether dissatisfaction with performance of valued activities predicts depression in patients with age-related macular degeneration (AMD). PATIENTS: Two hundred and six patients with newly diagnosed neovascular AMD in one eye and pre-existing AMD in the fellow eye who were participating in a clinical trial of a psychosocial intervention to prevent depression. MEASURES: Structured clinical evaluations of vision function, depression, visual acuity, contrast sensitivity and medical morbidity. Subjects were classified as dissatisfied if they indicated that they were dissatisfied with their performance of a valued activity.
RESULTS: Subjects who were dissatisfied with performance of valued activities (n = 71) had similar demographic characteristics to satisfied subjects (n = 135) but had worse visual acuity (p < 0.054), greater medical comorbidity (p < 0.006), and lower vision function (p < 0.001). Dissatisfied subjects were almost 2.5 times more likely (OR = 2.41; [95% CI 1.02, 5.65]; p = 0.044) to become depressed within 2 months than satisfied subjects independent of baseline visual acuity, vision function, and medical comorbidity.
CONCLUSION: Dissatisfaction with performance of valued activities in older persons with AMD predicts depression over a 2-month period. Assessing the ability to pursue valued activities may identify patients at risk for depression and prompt clinicians to initiate rehabilitative interventions and careful surveillance for depression.
