q2 · i? · review · r2

Narrative comparison in Section 3.2.2 of models whose participants were limited to school administration, students and teachers. The review reports that HeadOn and SUPEP "improved knowledge and attitudes without corresponding behavioural change." No effect sizes are printed.

"school-only models like HeadOn [93] and SUPEP [88] improved knowledge and attitudes without corresponding behavioural change."

Discussion¶

Related Claims¶

• Multi-stakeholder school interventions yielded broader and more durable outcomes than school-only models, though the pattern was not universal — possibly the same claim (merge candidate)
• Effects on secondary behavioural outcomes (conduct problems, delinquency, substance use) are negligible or non-significant — related
• Self-regulation interventions showed positive associations with distal outcomes: academic achievement in 11 of 13 studies (85%), substance abuse in 4 of 5 (80%), and conduct disorders, social skills, depression, behavioral problems, and school suspensions in all reporting studies. — related
• Positive developmental relationships and school connectedness protect against violence, absenteeism, and substance abuse, and increase threat reporting — related
• No school-based intervention model for students already using substances was found: all examined models were preventive or protective in approach — related
• Cultural tailoring moderated intervention effectiveness in the kiR programme family, with culturally grounded adaptations producing more favourable attitudes and behaviours — related
• Interventions that change educator behaviour to match standard global definitions of quality have delivered negligible effects on children's developmental outcomes — related
• Adolescent substance use is associated with low academic outcomes, delinquency, and risky sexual behaviors, per cited prior work — related
• School-based substance use interventions with an explicit theoretical foundation are associated with more robust outcomes than atheorised models, which more often showed fluctuating outcomes — related
