The current study aimed to test whether individuals with and without a chronic physical disease differ in levels of compassionate abilities, loneliness and quality of life (QoL); and to examine whether loneliness mediated the impact of self-compassion and of receiving compassion from others in physical, psychological, and social QoL. In this cross-sectional study, individuals with (n = 278) and without (n = 455) physical chronic disease were recruited through an online self-report protocol. The Compassionate Attributes and Engagement Scale, the UCLA Loneliness Scale, and the World Health Organization's QoL-BREF were used. Individuals with a chronic physical disease diagnosis reported lower compassionate abilities and QoL, as well as higher levels of loneliness, when compared to participants without a diagnosis. For both samples, compassionate abilities were negatively linked to loneliness, and positively linked to QoL. Path analysis results indicated that compassionate abilities have a direct effect on loneliness, which explains individuals' perceived QoL. Results highlight the crucial role of self-compassion skills and the ability to perceive others as compassionate, in loneliness and QoL, both in individuals with and without a chronic physical disease. These findings seem to have important research and clinical implications.
