Measuring Growth Mindset

Abstract. A growth mindset is a belief that personal characteristics, specifically intellectual ability, are malleable and can be developed by investing time and effort. Numerous studies have investigated the associations between a growth mindset and academic achievement, and large intervention programs have been established to train adolescents to develop a stronger growth mindset. However, methodological research on the adequacy of the measures used to assess a growth mindset is scarce. In our study, we conducted one of the first comprehensive assessments of the psychometric properties of Dweck’s widely used three-item Growth Mindset Scale in two samples (adolescents aged 14–19 years and adults aged 20–64 years). We test the comparability (i.e., measurement invariance) of the scale across these age groups. Furthermore, using the same two samples, we identified and validated a single-item measure to assess growth mindset in settings with severe time constraints. Results reveal that both the three-item and the single-item scales have acceptable psychometric properties regarding reliability, comparability, and validity. However, the results did not support some of the central tenets of mindset theory, such as that a growth mindset is positively linked to goal regulation and achievement, calling for future research on the criterion validity of a growth mindset.
