Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that, so far, is considered always fatal. Treatments mainly consist in increasing survival and aim to improve the quality of life of people with ALS (pwALS). Social support and spirituality have been shown to play a key role in pwALS’ quality of life. Our study explored it in depth by investigating the underlying mechanisms linking social support, spirituality, and emotional well-being.

Thirty-six pwALS underwent a battery of tests evaluating emotional well-being (emotional well-being scale of the 40-item Amyotrophic Lateral Sclerosis Assessment Questionnaire), social support (6-item Social Support Questionnaire), and spiritual well-being (12-item Functional Assessment of Chronic Illness Therapy – Spiritual well-being). Our recruitment was web-based through the FILSLAN and the ARSLA websites as well as through Facebook® advertisements (ALS groups). Data were analyzed by Pearson correlation analysis and Process macro was used in an SPSS program to analyze the mediator variable effect.

Availability of social support, spiritual well-being, and 2 of its dimensions, i.e., meaning and peace, were positively correlated with emotional well-being. The mediational analyses showed that spiritual well-being, meaning, and peace act as mediators in the association between availability of social support and good emotional well-being.

Availability of social support and spirituality are essential for the emotional well-being of pwALS. Spirituality as a mediator between availability of social support and emotional well-being appears as real novel finding which could be explored further. Spiritual well-being, meaning, and peace appear as coping resources for pwALS. We provide practical guidance for professionals working with pwALS.
