Abstract 

          Objective  To investigate the measurement model of the mindset questionnaire and the validity study.

          Materials and methods  A group of 530 cases (i.e. teachers, university students, psychiatric caregivers) was random sampling into 2 groups. Exploratory structural equation modeling (ESEM) analysis was done in a sample of 130 cases. The confirmatory factor analysis (CFA) and invariance studies were analyzed in the other group (400 cases) by using the Mplus. All cases had to complete the 10–item mindset questionnaire. The fit indices were RMSEA, CFI and TLI.

          Results  ESEM showed that 9 items were retained and divided into 2 domains and then CFA was confirmed in a group of 400 cases that the 8-item and 2-dimension questionnaire was congruent with the goodness of fit indices (CFI = 0.97,  TLI = 0.95,  RMSEA = 0.04) and factor loading ranged from 0.29 to 0.89. The measurement model invariance was shown between gender and two levels of education. The composite reliability of the 8-item questionnaire was good (0.90).

          Conclusion  The mindset questionnaire consisting 8 items dividing into 2 domains, i.e., growth and fixed, had the good validity among variety of samples.
