Glaucoma adversely affects subjects’ ability to accomplish daily activities, engage in social roles, and contributes to disability. Yet methods to evaluate glaucoma-related disability are limited. To identify daily activities and social roles associated with glaucoma, this study (1) tests the association between visual field (VF) and the Assessment of Life Habits (LIFE-H), a questionnaire developed to measure the degree of difficulty and the level(s) of assistance subjects require in order to accomplish daily activities and social roles, and (2) identifies LIFE-H items with high differential capability of person functional ability.
We recruited 101 subjects aged 50 years and older diagnosed with glaucoma who underwent comprehensive ophthalmic evaluation and VF testing (Humphrey Field Analyzer, Zeiss, Dublin, CA) whom were administered the LIFE-H. Better-eye VF mean deviation (MD) was used to measure severity of visual impairment. Multivariable regression analyses determined the association between MD and 11 LIFE-H domains (totaling 37 daily activity and 38 social role items), adjusting for the covariates age, gender, race, comorbidities, and depressive symptoms. Domains not significantly associated with MD and items not applicable to 10% of subjects were excluded from further analyses, resulting in 64 qualified subjects and 40 LIFE-H items. Rasch analysis was used to determine the item hierarchical order based on the level of person ability.
64 subjects of average age 66±10 years and better-eye MD of -5.0±7.4 dB qualified for the analysis. All LIFE-H domains except interpersonal relationships were significantly associated (p ≤ 0.05) with MD. Overall, average domain scores were high (range, 8.7±1.5 to 9.7±0.4) with the lowest scoring domains being mobility, employment, and recreation. Of the 40 LIFE-H items, 29 were daily activities and 11 were social roles. 21 items across 6 domains were detected to have high differential capability; of which 11 items were daily activities and 10 items were social roles. 11 of the 21 items were significantly associated with MD; 8 of which were social roles and 3 daily activities.
The large impact of the social role items among the LIFE-H questionnaire highlight the psychosocial factors for subjects with glaucoma. Further evaluation of daily activities and social roles that constitute when and how glaucoma affects subjects is needed.
