Abstract
Our aim was to estimate the validity of the Global Activity Limitation Indicator (GALI) when measuring the severity level of disability. Data came from 153 residents of Spain, who requested an evaluation of their degree of disability. We compared disability classifications (severe vs. non-severe) from GALI against those from the 36-item questionnaire WHODAS 2.0, the current gold standard measure of disability. The sensitivity of GALI to detect severe disability was 58.3% [95% confidence interval (CI):43.2–72.4], and the specificity was 84.8% (95% CI: 76.4–91.0). Thus, the validity of GALI to accurately categorize the degree of severity of an individual’s disability is not high, this in great part due to its limited sensitivity.This publication has 6 references indexed in Scilit:
