摘要

Background

A school-based health promotion strategy (Weitblick: ‘foresight’) is currently being piloted in Germany; it is based on the internationally established prevention system Communities That Care (CTC). This capacity-building intervention has an effect on students by strengthening the school’s capacity to adopt a science-based approach to prevention. This paper examines the extent to which Weitblick achieves this capacity building.

Methods

The study is based on a sequential design in which a control group (CG) is constructed from the baseline data of later sequences. Between September 2023 and March 2026, 51 schools were recruited, of which 29 were assigned to the CG and 11 to the intervention group (IG). Outcomes were assessed using biannual multiple key informant surveys (n = 356). The data were aggregated at school level. The primary outcome is the adoption of science-based prevention. Secondary outcomes are sectorial collaboration, an integrated overall strategy, support for prevention, and social norms. Paired t‑tests were performed.

Results

For the primary outcome, an improvement was observed exclusively in the IG (g = 0.82; 95% confidence interval [CI] 0.15–1.45). For the secondary outcomes, an improvement in sectorial collaboration was also observed only in the IG (g = 0.66; 95% CI −0.03 to 1.45). In contrast, a deterioration in social norms was observed in the IG (g = −0.93; 95% CI −1.91 to −0.15), although this was also observed in the CG.

Conclusion

The effects found are comparable to those of CTC and support the effectiveness of this approach adapted for schools. Limitations of the study design are discussed.
