Does emotion regulation mediate the relationship between self-compassion and subjective well-being? A cross-sectional study of adults living in the United States.

Subjective well-being influences mental and physical health. Fortunately, interventions exist to improve people's subjective well-being. Emotion regulation and self-compassion are two transdiagnostic factors that impact mental health and have been separately shown to be associated with subjective well-being. However, their combined relationship with subjective well-being has not yet been examined. To address this gap, the current novel study aimed to determine if there is a combined relationship between self-compassion, emotion regulation, and dimensions of subjective well-being cross-sectionally in adults living in the United States. Participants ( n  = 559; 50% female; M age  = 57.70 years) completed an online survey via Prime Panels from CloudResearch, capturing their responses on the interested constructs. Analyses showed that emotion regulation significantly mediated the relationships between self-compassion and various subjective well-being dimensions, specifically, positive affect ( d  = 0.32), negative affect ( d  = 1.17), and eudemonic well-being ( d  = 0.79). Our findings have both clinical and research implications.
