Growth Mindset Scale: Aspects of reliability and validity of a new 8-item scale assessing growth mindset

In this article, the psychometric properties of a new scale aimed at quantifying Growth Mindset are explored. Growth Mindset Scale is a quantitative measure which is context independent and simple to administer. Growth Mindset Scale was tested on 723 participants between 16 and 85 years of age (mean age = 28.56, SD = 12.14), which allowed for the exploration of feasibility, internal consistency, and construct validity. The results indicate that the growth mindset scale is applicable for the age studied (16–85). All individual item scores showed a positive correlation with the total score and ranged between 0.45 and 0.63. The Cronbach's alpha value was 0.83 for the standardized items. Pearson's correlation coefficient between the total score of the Growth Mindset Scale and the total score of Theories of intelligence scale was r = 0.168 (p < 0.001). These encouraging results assure additional improvement of the growth mindset scale, involving normalization based on a larger, representative sample.
