The experience of grace is currently attracting increased empirical interest. Validated instruments to assess aspects of the experience of grace in a secularized context are scarce which limits current psychological research on grace in other than highly religious populations. We present a bottom-up construction of the Experiencing Grace Scale (EGS) and evidence supporting its reliability and validity. Confirmatory factor analysis showed a good fit for the four subscales: Appraising Grace, Giving Grace, Receiving Grace, and Divine Grace. Reliability analysis showed overall (...) good internal consistency and test–retest stability. Convergent validity was demonstrated by means of expected associations between subscales of the EGS and other relevant measures. Predictive validity was confirmed by associations between subscales of the EGS at measurement Wave 1 with mental well-being scales at Wave 2. The EGS contributes to further research on the experience of grace and its relationship to other psychosocial variables in the field of positive psychology. (shrink)
