ABSTRACT

BACKGROUND

The school-based Dutch Obesity Intervention in Teenagers (DOiT) program is an evidence-based obesity prevention program. In preparation for dissemination throughout the Netherlands, this study aimed to adapt the initial program and to develop an implementation strategy and materials.

METHODS

We revisited the Intervention Mapping (IM) protocol, using results of the previous process evaluation and additional focus groups and interviews with students, parents, teachers, and professionals.

RESULTS

The adapted 2-year DOiT program consists of a classroom, an environmental and a parental component. The year 1 lessons aim to increase awareness and knowledge of healthy behaviors. The lessons in year 2 focus on the influence of the (obesogenic) environment. The stepwise development of the implementation strategy resulted in objectives that support teachers' implementation. We developed a 7-step implementation strategy and supporting materials by translating the objectives into essential elements and practical strategies.

CONCLUSIONS

This study illustrates how revisiting the IM protocol resulted in an adapted program and tailored implementation strategy based on previous evaluations as well as input from different stakeholders. The stepwise development of DOiT can serve as an example for other evidence-based programs in preparation for wider dissemination.
