Self-compassion means being supportive and kind to oneself when experiencing failure or inadequacies. It is associated with adaptive intrapersonal and relational outcomes for individuals. This evidence was extended by using an Actor-Partner Interdependence framework. Other-sex couples (N = 209) completed measures of self-compassion, relationship-specific self-compassion, and relationship satisfaction. Both self-compassion measures were related to global relationship satisfaction and facets thereof (e.g., sexuality, engagement, trust) for actors. Relationship-specific self-compassion was also positively related to the partner's relationship satisfaction (particularly for men). It is suggested that researchers (a) consider the interdependence of the partners when analyzing self-compassion in relationships and test for partner effects and (b) use fine-grained and domain-specific measures to develop a more complete understanding of self-compassion's associations with criterion variables.
