Background: Research emphasizes the relevance of mindsets for SRL and academic achievement. Aims: This paper reports three studies that aim to detect profiles of mindsets about SRL and intelligence, examine their relationship with students' SRL, study-related beliefs, and academic achievement, and replicate the findings across samples. Sample: Participants were Ntotal = 633 university students, with NStudy1 = 254, NStudy2 = 187, and NStudy3 = 192. Methods: LPAs were run to identify mindset profiles, and Mplus' auxiliary (BCH) function was applied to examine mean differences across profiles. Results: All three studies identified the mindset profiles "Entity-Theory", "Balanced-Theory", and "SRL-Theory". The analyses revealed an SRL-Theory advantage regarding SRL, study-related beliefs, and academic achievement. Conclusions: These are the first studies to explore mindset profiles based on mindsets about SRL and intelligence. The identified mindset-based meaning systems provide diagnostic information for teaching and tailored interventions and stimulate the advancement of SRL and mindset theories.
