As growth mindset interventions increase in scope and popularity, scientists and policymakers are asking: Are these interventions effective? To answer this question properly, the field needs to understand the meaningful heterogeneity in effects. In the present systematic review and meta-analysis, we focused on two key moderators with adequate data to test: Subsamples expected to benefit most and implementation fidelity. We also specified a process model that can be generative for theory. We included articles published between 2002 (first mindset intervention) through the end of 2020 that reported an effect for a growth mindset intervention, used a randomized design, and featured at least one of the qualifying outcomes. Our search yielded 53 independent samples testing distinct interventions. We reported cumulative effect sizes for multiple outcomes (i.e., mindsets, motivation, behavior, end results), with a focus on three primary end results (i.e., improved academic achievement, mental health, or social functioning). Multilevel metaregression analyses with targeted subsamples and high fidelity for academic achievement yielded, d = 0.14, 95% CI [.06, .22]; for mental health, d = 0.32, 95% CI [.10, .54]. Results highlighted the extensive variation in effects to be expected from future interventions. Namely, 95% prediction intervals for focal effects ranged from -0.08 to 0.35 for academic achievement and from 0.07 to 0.57 for mental health. The literature is too nascent for moderators for social functioning, but average effects are d = 0.36, 95% CI [.03, .68], 95% PI [-.50, 1.22]. We conclude with a discussion of heterogeneity and the limitations of meta-analyses. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Despite mounting interest in growth mindset interventions, this approach has yet to be applied to the domain of entrepreneurship. In the present research, we developed and tested if a growth mindset intervention could be leveraged to promote students’ entrepreneurial self-efficacy and if this, in turn, predicted career development (i.e., academic interest, career interest, task persistence, and academic performance). We report on our findings, from an Open Science Framework (OSF) preregistered study, that is a randomized controlled trial implementing a growth mindset intervention. We randomly assigned undergraduate students (N = 238) in an introduction to entrepreneurship class to either the growth mindset intervention or to a knowledge-based attention-matched control. Students in the growth mindset intervention, relative to the control, reported greater entrepreneurial self-efficacy and task persistence on their main class project. The intervention also indirectly improved academic and career interest via entrepreneurial self-efficacy. However, the intervention failed to directly or indirectly impact performance on a classroom assignment. Additionally, and somewhat surprisingly, gender and past experience in the field failed to moderate any effects of the intervention on outcomes. Theoretical implications, limitations, and future directions are discussed.

Purpose: The topic of entrepreneurial intention, which refers to a person’s degree of interest in creating a new business venture, has received close scrutiny in the entrepreneurship literature. The empirical results regarding the relation between emotional intelligence (EI) and entrepreneurial intention were nevertheless mixed across studies. Based on fit theory and trait activation theory, the purpose of this paper is to explain the fundamental reason for the mixed findings in the extant literature thus far.Design/methodology/approach: Random-effects meta-analyses, based on 12 studies (along with 12 effect sizes), were performed to not only investigate the overall relation between EI and entrepreneurial intention but also to examine the moderators (i.e. individualism (vs collectivism), masculinity (vs femininity), power distance, long-term orientation (vs short-term orientation), uncertainty avoidance, and indulgence (vs restraint)) that influence this relation.Findings: The results of this meta-analysis demonstrated that EI is positively related to entrepreneurial intention; the positive relationship between EI and entrepreneurial intention is stronger in long-term-oriented cultures; and the positive relationship between EI and entrepreneurial intention does not significantly differ based on a culture’s level of collectivism, masculinity, power distance, uncertainty avoidance, and indulgence.Originality/value: This meta-analysis advances the current understanding of the relation between EI and entrepreneurial intention from cross-cultural perspectives.
