Poor vision, functioning, and depressive symptoms: a test of the activity restriction model

Area of Science:

• Gerontology
• Ophthalmology
• Psychiatry

Background:

• The activity restriction model posits that stressors in late life impact mental health directly and indirectly through functional limitations.
• Poor vision is a common stressor in older adults that may affect mental health via functional restrictions.

Purpose of the Study:

• To test the applicability of the activity restriction model to the context of poor vision in late life.
• To examine how subjective and objective vision impact mental health and daily functioning in older adults.

Main Methods:

• Data from a national probability-based sample of 1,178 older adults (mean age 69.2 years) were analyzed.
• Vision was assessed subjectively (self-report) and objectively (visual acuity test).
• Physical limitations, driving limitations, social isolation, and depressive symptoms were measured.

Main Results:

• Subjective vision strongly predicted depressive symptomatology directly and indirectly through physical limitations and social isolation.
• Objective vision predicted physical and driving limitations but was not associated with social isolation or depressive symptoms.
• The activity restriction model fit well for subjective vision, but not objective vision.

Conclusions:

• Poorer self-rated vision in late life contributes to lower mental health directly and indirectly by restricting physical activities and increasing social isolation.
• Interventions for older adults with vision problems should prioritize maintaining/enhancing physical and social functioning.
• These findings support the activity restriction model and suggest targeted interventions for vision-related mental health.
