Association of vision loss and depressive symptomatology in older adults assessed for ocular health in senior living facilities.

PURPOSE People with vision loss are at increased risk for major depressive disorder (MDD) and subclinical depression. However, screening for depression is rarely done in eye care settings or among groups in the general population known to have vision disorders. METHODS We examined the prevalence of depression, using the Patient Health Questionnaire - 2 (PHQ-2), among a group of older adults (N = 204; mean age = 82.15) at two senior living facilities (SLFs) and determined the relationships between severity of depression and objective visual findings, visual function, beliefs about taking an active role in one's own eye care (i.e., patient activation) and level of social support. RESULTS Approximately 50% of the sample had impaired vision in at least one eye, and close to 30% of the sample obtained a score on the PHQ-2 indicating the likely presence of major depressive disorder. Visual testing findings were related to visual function (e.g., ability to read), but not to depression. Patient activation was also not significantly related to the level of depression. However, impaired visual functioning and less social support were both strong predictors of depression. These two variables and their interaction accounted for 17% of the total PHQ-2 score variance. CONCLUSIONS These data indicate the potential utility of screening for depression as part of vision care in populations likely to have significant vision loss. The findings also suggest that a comprehensive approach to depression prevention and/or reduction in SLF and similar populations may require interventions to address reduced visual functioning and methods to strengthen social networks.
