Quality of Life Structural Equation Model for Patients With Amyotrophic Lateral Sclerosis

Abstract

Purpose The aim of the study was to propose and test a quality of life model among Korean patients with amyotrophic lateral sclerosis (ALS) using structural equation modeling. Design A cross-sectional study was performed. Methods Data from 184 patients with ALS were collected from two university hospitals in Seoul and Busan, South Korea, between June and December 2018. Findings The modified model indices indicated adequate data fit. Quality of life predictors were social support, physical functional status, depression, and general health perception. Conclusion This study improved the understanding of quality of life for Korean patients with ALS, including complex direct and indirect relationships among quality of life factors.
