Abstract
This study examined two widely available light-touch, writing-based mindset interventions: one that targeted students’ purpose for learning and one that aimed to increase students’ growth mindset. In order to examine the potential mechanisms underlying previously reported effects of mindset interventions, we analyzed these interventions’ effects on low-income, ethnic minority adolescents’ academic outcomes, task persistence, task-relevant anxiety, critical motivation, and sense of belonging. Results indicated that the purpose for learning intervention had a small negative impact on students’ self-reported grades the following year, and null results for the other outcomes. The growth mindset intervention was administered one year following the purpose for learning intervention and we found no evidence of treatment impacts on any outcomes. Analyses of treatment impact moderation suggested that certain student characteristics, such as student gender and race could play a role, but most of these tests also presented null results. The primarily null results of both interventions suggest that further study is needed to determine the effectiveness of one-time, self-administered mindset interventions across a variety of contexts and student populations.

Notes
1 At the time of publication, the two online modules at http://www.perts.net were specific to the Growth Mindset intervention described in this article.
2 Minor modifications were made to update the language and to cater it to the population of study, while retaining the language and themes that made the interventions effective in prior trials. See the Supplementary appendix for a detailed description of the changes made to the original Yeager et al. (Citation2014) and Yeager, Lee, et al. (Citation2016) interventions.
3 Another 8% of the sample completed the tasks on their own computers at home with continuous guidance from an assessor over the phone. A remaining 1% (4 participants) completed the tasks in a location such as a restaurant/café or a parent’s workplace. This flexibility in administration setting allowed us to retain as large a sample size as possible.
4 The 29% of students who were still in middle school during administration were verbally instructed by assessors to focus on the differences between elementary school and middle school.
