This paper systematically reviews the psychometric rigor of resilience measurement scales developed for use in general and clinical populations. The review searches eight electronic databases and reference lists, focusing on peer-reviewed journal articles where resilience is a key focus or assessed. Nineteen resilience measures were reviewed, with four being refinements of original measures. All measures had some missing information regarding psychometric properties. The Connor-Davidson Resilience Scale, the Resilience Scale for Adults, and the Brief Resilience Scale received the best psychometric ratings. However, the conceptual and theoretical adequacy of several scales was questionable. The review found no current 'gold standard' among 15 measures of resilience. Many scales are in the early stages of development and require further validation. Given the increasing interest in resilience from major international funders, policymakers, and practitioners, researchers are urged to report relevant validation statistics when using these measures.This paper systematically reviews the psychometric rigor of resilience measurement scales developed for use in general and clinical populations.
