Abstract

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.

成长心态量表：新的 8 项成长心态评估量表的信度和效度

本文探讨了一种旨在量化 "成长心态 "的新量表的心理测量特性。对 723 名年龄在 16-85 岁之间的参与者（平均年龄为 28.56 岁，标准差为 12.14 岁）进行了测试，从而探讨了该量表的可行性、内部一致性和建构效度。结果表明，成长心态量表适用于所研究的年龄段（16-85 岁）。所有单项得分均与总分呈正相关，相关范围在 0.45 至 0.63 之间。标准化项目的 Cronbach's alpha 值为 0.83。成长心态量表的总分与智力理论量表的总分之间的皮尔逊相关系数为 r = 0.168 (p < 0.001)。这些令人鼓舞的结果保证了成长心态量表的进一步改进，包括在更大的代表性样本基础上进行标准化。
