q2 i1 6th graders significantly outperformed their comparison group (p = 0.026; effect size = 0.07), whereas no significant differences were detected for 7th grade (p = 0.204) or 8th grade (p = 0.594). → Feng 2025

Grade-level subgroup analysis of the quasi-experimental sample (predominantly 7th graders, N = 2,121; 6th graders N = 383; 8th graders N = 351). The article suggests the intervention "may be particularly beneficial when introduced earlier in middle school."

"The analysis revealed that students in 6th grade significantly outperformed their comparison group (p = 0.026; effect size = 0.07), whereas no evidence of significant differences was detected for students in 7th grade (p = 0.204) or 8th grade (p = 0.594)"
