Abstract
Whilst mindfulness as a practice is now well researched, little is known about the associated concept of equanimity or the barriers people face in achieving it. Three studies were conducted to develop and validate a self-report measure assessing barriers to equanimity. Across studies, opportunity samples comprised students and staff members from one British university, and via online social media platforms. In study 1 (n=453) principal component analysis revealed five internally consistent factors measuring the ways in which barriers to equanimity are conceptualised. Study 2, (n=108) sought to confirm these factors. Results revealed that a fourfactor model best fit the data. Validity statistics were sufficient to support this model. Study 3 (n=302) tested convergent and discriminant validity of the four-factor Equanimity Barriers Scale (EBS). It was tested utilising the Mindfulness Attention Awareness Scale (Brown & Ryan, 2003), Big Five Inventory-10 (Rammstedt & John, 2007), Self Compassion Scale Short Form (Raes, Pommier, Neff & Van Gucht 2011), Difficulty in Emotional Regulation Scale Short Form (Kaufman, Xia, Fosco, Yaptangco, Skidmore & Crowell 2015) and the Emotional Regulation Questionnaire (Gross & John, 2003). The usefulness of the EBS for future research into individual differences in adherence to mindfulness-based interventions are discussed.
