Aim: This study examined the validity and reliability of the Analysing and Developing Adaptability and Performance in Teams to Enhance Resilience (ADAPTER) Scale in a sample of Chinese nurses. Background: Nurse shortage caused by job stress in China is becoming more acute, while research on team resilience training among nurses is still rising. To accurately and consistently describe team resilience status prior to training and evaluate the effects of resilience interventions at the team level among nurses, it is critical to develop a valid and reliable Chinese measure. Methods: This was a cross-sectional study of 838 nurses. The scale was translated into Chinese according to Brislin's guidelines. Validity was evaluated by content validity, discriminative validity, exploratory and confirmatory factor analyses and convergent validity. Reliability was estimated by item-to-total correlations, internal consistency and test-retest reliability. Results: Exploratory and confirmatory factor analyses revealed a four-factor model. Content validity was good and discriminative validity showed a significant discriminative ability. The concurrent validity was acceptable. The reliability was demonstrated with item-to-total correlations of greater than .40, Cronbach's alpha of .97 and intraclass correlation coefficients of .946. Conclusions: The Chinese version of the scale is a valid and reliable instrument. Implications for Nursing Management: The scale can provide insight into nurses' team resilience and thereby inform the development of specific interventions aimed at improving the team resilience of nurses.
