The character strength of forbearance contributes to peace in broader society, as well as familial harmony. Although forbearance is essential to healthy interpersonal relationships, no psychometrically sound measure has been developed to assess the multi-dimensional nature of forbearance. The present set of studies describes the development and initial validation of the Forbearance Scale (FS). In Study 1, items were generated from focus group interviews with college students (n = 43) to establish the content validity of the scale. In Study 2, the factor structure of the FS was determined using exploratory factor analysis of data from college students (n = 466). In Study 3, the factor structure of the FS was cross-validated with a community sample (n = 579) by means of confirmatory factor analysis. The final scale, the FS-16, consists of 16 items with four factors: (1) emotional calmness, (2) overlook others' misdeeds, (3) tolerance and acceptance, and (4) self-restraint. Hierarchical multiple regression analyses provided evidence of convergent and concurrent validity. The FS-16 demonstrates potential as a new personality assessment tool for measuring forbearance.
