This study explored the correlation between mental toughness (MT) and physical activity (PA), and the moderation role between PA intention and subsequent behavior among college students and wage earners. Five hundred ninety-one college students (251 male, 340 female) aged from 19 to 24 and 285 (157 male, 127 female) wage earners aged from 27 to 58 recruited from seven colleges and five cities in China. A Theory of Planned Behavior (TPB) questionnaire, MT Inventory, and the International PA Questionnaire was completed online. Results showed that attitudes, subjective norms, and perceived behavioral control explained 46.5 and 38.3% variance in PA intention among college students and wage earners separately. Intention predicted PA behavior significantly among college students and wage earners. Structural equation modeling indicated that the TPB model and the moderation model have an adequate to good fit except the TPB model among wage earners. MT was positively correlated with PA among college students and wage earners and had a significant moderation role in intention-behavior gap among college students and partially affected the transfer of PA intention to behavior among college students. Individuals with high MT had high levels of PA regardless of intention, while PA of those with low MT was low and unstable. Future research should further explore the correlation between intention and PA and the moderation role of MT in different populations using a longitudinal study in order to better understand the correlation between intention and PA, and the transition from intention to PA and better guidance PA intervention to promote PA.

This study examines the reliability and validity of the Characteristics of Resilience in Sports Teams Inventory (CREST) in Chinese team athletes. A sample of 659 athletes (male = 355, female = 304) aged from 16-34 (M = 20.08, SD = 2.98) participated in this study. The scale was translated into Chinese using forward and back translation procedures by two independent translators. Questionnaires were administered online. Data was analysed using SPSS 19.0 and Mplus 6.0. Results showed that the items were understood by Chinese team sport athletes. Exploratory factor analysis showed that the Chinese version of CREST had two sub-dimensions as it was in the original scale. Confirmatory factor analysis further demonstrated that the two-structure model was confirmed in the Chinese team sports context. The Cronbach's alpha values of the scale was 0.842, and the test-retest reliability coefficient of one-month interval was 0.836. It is concluded that the Chinese version of CREST can be used as a valid and reliable tool to assess team resilience in China and can be helpful and applicable in helping sports psychologists understand team resilience. Future studies should further examine the psychometric properties of the scale among world-class athletes and develop a team resilience measurement tool based on Chinese traditional culture.
