OBJECTIVE: To develop and evaluate the 23-item quality of life (QoL) 125 scale contained four subscales for children with bilateral congenital cataract.
METHODS: 18 children with normal visual acuity and 76 patients with congenital bilateral cataract (age range of 8 years to 15 years) were evaluated with QoL. The 23-item QoL scale contained the following subscales: visual function, self-care, sociality, and mentality. Dispersion, correlation coefficient, factor analysis, discrimination analysis, Cronbach alpha and test-retest reliability were applied to select the parameters and data analysis.
RESULTS: The new scale included 20 items after screening. The correlation coefficients of content validity of each item and subscale were beyond 0.6 (P < 0.05). Statistically significant difference was found at discrimination analysis between normal and cataract children (P' = 0.000), the differences was also demonstrated between preoperative and postoperative cataract children (P' = 0.000). The coefficient of test-retest reliability was 0.895 (P = 0.000), and the Cronbach's alpha coefficients of four subscales were 0.822, 0.922, 0.797, and 0.794 respectively. The statistics value of effective size was 1.141.
CONCLUSIONS: significant reliability, validity and responsibility to change life quality were achieved in the 20-item scale of QoL for children with bilateral congenital cataract. This scale can be applied to evaluate the life quality of bilateral cataract children.
