The Effect of Vocational Training on Visually Impaired People’s Quality of Life

Abstract

Background: Quality of life (QOL) is frequently utilized in clinical medicine and research to assess a patient’s health status and treatment effectiveness. Objectives: This study investigates the impact of vocational training on the QOL of visually impaired individuals. Methods: We employed the brief Taiwan version of the World Health Organization QOL Questionnaire (WHOQOL-BREFTW) to assess four domains: physical, psychological, social, and environmental, using a nonequivalent pretest–posttest control group design. The experimental group participated in 6 months of vocational training, including life and career reconstruction. After completing the vocational training, the average QOL score for the experimental group was 3.34 ± 0.18, while the control group had a score of 3.10 ± 0.85. The generalized estimating equation (GEE) results revealed a notable improvement of 10.81 (1.10) in the posttest overall QOL scores compared to the pretest scores in the control group. Conclusion: Vocational training significantly improves the overall QOL for visually impaired individuals. It is noteworthy that the psychological, social relationship, and physical health domains of WHOQOL-BREF TW exhibited the most significant improvements. This emphasizes the following: 1. professional knowledge and technical learning can enhance the abilities of the visually impaired. 2. The improvement in QOL occurs primarily at physical, psychological, and social levels. These levels involve maintaining physical health, reducing dependence on medical care, and enhancing self-care abilities for life reconstruction. 3. Integrating electronics with directional action can help to mitigate the risks associated with outdoor activities.
