Through a cluster randomized controlled trial, a classroom-based intervention, aimed to improve incremental beliefs, was implemented in first-year classes of secondary education. Use of a mobile neurofeedback device was incorporated in the intervention to create for students an experience of controllability. Long-term impact of the intervention was evaluated through multilevel models with students at level 1 and classes at level 2. The intervention (n = 222) improved students’ academic achievement one year post-intervention, compared to an active control condition (n = 217). No long-lasting intervention effect on students’ experience of school-related stress was found. Further, socioeconomic status as a student characteristic did not appear to moderate intervention effectiveness for long-term outcomes.Show less
