What predicts changes in useful field of view test performance?

Area of Science:

• Gerontology
• Cognitive Neuroscience
• Ophthalmology

Background:

• The Useful Field of View Test (UFOV) is a long-standing measure of age-related visual processing and cognitive changes.
• Previous research has not longitudinally examined how UFOV performance changes with age or its influencing factors.
• UFOV performance is a key indicator for everyday functional outcomes, notably driving ability.

Purpose of the Study:

• To investigate predictors of change in UFOV performance over a 5-year period.
• To examine the longitudinal relationship between aging and UFOV performance.
• To compare the trajectory of UFOV changes with cognitive speed measures.

Main Methods:

• Longitudinal analysis of control group participants (N=690) from the ACTIVE study.
• Random effects models used to assess 4-subtest-total UFOV as the outcome.
• Predictors included baseline age, education, gender, race, visual acuity, depressive symptoms, mental status, self-rated health, and attrition.

Main Results:

• UFOV performance exhibited a curvilinear pattern, initially improving and subsequently declining over the 5-year study period.
• Increased age was the sole consistent predictor associated with greater declines in UFOV performance over time.
• The trajectories of change for UFOV and the Digit Symbol Substitution subtest (a measure of cognitive speed) were similar.

Conclusions:

• Aging significantly impacts UFOV performance, leading to progressive declines in visual processing and cognitive function.
• The findings highlight the importance of considering age as a primary factor in UFOV performance changes.
• The parallel changes in UFOV and cognitive speed suggest interconnected age-related declines in sensory and cognitive processing.
