This study sought to provide the initial psychometric evidence supporting a new measure of resiliency. In consideration of the shortcomings of previous measures, a more comprehensive measure was developed based on the theoretical model of King and Rothstein (2010). The resulting measure, the Workplace Resilience Inventory (WRI), encompasses an individual's personal characteristics, social support network, initial responses to a significant and life changing event, and self-regulatory processes. Following a rigorous, theoretically-based, and empirically-supported procedure for selecting items, the facets of the WRI demonstrated acceptable internal consistency, as well as adequate independence. The WRI demonstrates significant relations with important well-being criteria, such as satisfaction with life, depression, and perceived stress, and demonstrates incremental validity above and beyond a previously validated measure of resiliency, the Psychological Capital (PsyCap) questionnaire.
