Someone with social self-compassion is typically kind and understanding towards themselves in response to real or perceived negative evaluation from others in difficult interpersonal situations (e.g., being mistreated, feeling inadequate, or making a mistake in public). Initial research findings support the usefulness and value of measuring self-compassion in a way that captures domain-specificity, in this case within the social sphere. More specifically, current research supports the reliability and validity of the Social Self-Compassion Scale, as it uniquely predicts outcomes over and above general self-compassion, such as perceived social self-efficacy, fear of negative evaluation, general feelings of mattering, and psychological well-being. The purpose of this chapter is to introduce and outline the Social Self-Compassion Scale published in 2021. This chapter will first contextualize the construct of social self-compassion and its relevancy for use in educational, clinical, and research contexts. Additionally, this chapter includes a description of the scale development and validation as well as extension of research findings supporting the utility of the measure.
