• [abstract] 53 independent samples from randomised growth-mindset intervention studies published 2002–2020.
• [abstract] For academic achievement, in targeted subsamples (those expected to benefit most) with high implementation fidelity: d = 0.14, 95% CI [.06, .22]; 95% prediction interval −0.08 to 0.35.
• [abstract] Mental health d = 0.32 [.10, .54]; social functioning d = 0.36 [.03, .68], PI [−.50, 1.22]. The authors stress the wide expected variation between future interventions.

Limits

• [assessment] Abstract only. "Targeted subsamples" is broader than C13's lower-achieving secondary students and includes other groups expected to benefit; not limited to short online lessons. Published in the same journal issue as Macnamara & Burgoyne 2023, which C13 already cites and which reaches a more sceptical reading.

Why it is in the library

C13 cites Macnamara & Burgoyne 2023 but not the companion meta-analysis that reaches a more positive conclusion for targeted groups; having both lets the nightly run weigh them against each other.
