Increasing the level of correspondence between measures of growth mindset and their related outcomes could afford more precise prediction of the relationships between growth mindset and social-emotional outcomes. To illustrate the value of measurement correspondence, two studies were conducted in Hong Kong. Study 1 showed that an agent-correspondent growth mindset measure (parents’ perception of the malleability of their children's personal qualities), compared to an agent-non-correspondent one (parents’ belief in the malleability of personal qualities of a generalized other), had stronger predictive relationship with children's likelihood of displaying difficult behaviors. Study 2 found that children's self-theories about the malleability of their intelligence (an intrapersonal construct) had stronger predictive relationship with academic engagement (an intrapersonal outcome) than did their perception of growth mindset norm (a normative construct). However, perceived growth mindset norm regarding personal qualities had stronger predictive relationship with peer relationship quality (an interpersonal outcome). Together these results demonstrated that when corresponding measures of growth mindset were used to predict an outcome, more reliable growth mindset effects would emerge.
