Design statement from the abstract: the study applied cubic RSA "as well as replication data" from TIMSS 2015 (N = 169,269) and a college SDT dataset (N = 270), the latter using the Academic Motivation Scale to match SDT measurement approaches more closely.

"as well as replication data (N = 169,269 8th grade students from TIMSS 2015, N = 270 college students from SDT data)"

• SDT-based predictions on motivation and achievement hold for about 93% of students but may not generalize to extreme states of autonomous or controlled motivation — related
• Across 37 countries, polynomial models with nonlinear or interactive effects of autonomous and controlled motivation on mathematics achievement always fit better than linear additive-only models — related
• In 14 countries, a cubic effect of autonomous motivation best fit the motivation-achievement relation, explaining 10.7% of achievement variance (an 8.1% increase over the additive model) — related
