The correlation between social support, coping style, advance care planning readiness, and quality of life in patients with amyotrophic lateral sclerosis: a cross-sectional study.

OBJECTIVE The primary goal for clinical healthcare professionals is to enhance the quality of life (QOL) of patients with amyotrophic lateral sclerosis (ALS). This study aimed to explore the correlation between social support, coping style, advance care planning (ACP) readiness, and QOL in patients with ALS. We also sought to analyze the mediating effect of coping style and ACP readiness between social support and QOL, and to provide insights for developing targeted interventions to improve patients' QOL. METHODS A cross-sectional design was used, with participants recruited through convenience sampling in Tianjin, China. Statistical analysis included the t-test, analysis of variance, correlation analysis, and mediating effect analysis. RESULTS The study included 215 participants. The QOL of patients with ALS was at a medium level, with significant correlations between social support, coping style, ACP readiness, and QOL (all p < 0.01). The direct effect of social support on QOL was 0.403 (p = 0.018), accounting for 41.85% of the total effect. The total indirect effect of social support on QOL through coping style and ACP readiness was 0.560 (p < 0.001), accounting for 58.15% of the total effect. The chain mediating effect involving facing, avoiding, and ACP readiness accounted for 16.72%. CONCLUSION Social support directly influenced QOL and had an indirect impact through coping style and ACP readiness. Healthcare professionals can improve the QOL of patients with ALS by enhancing social support, disease-coping ability, and ACP readiness in clinical practice.
