Process Evaluation of the IDEFICS Intervention
Process evaluation is an essential part of intervention evaluation that is often overlooked or reported limitedly. This chapter explains in detail how the process evaluation within the IDEFICS study was developed and how the different measures were built. For each intervention module, different measures were developed to integrate multiple perspectives on the implementation. All measures were based on the framework of Linnan and Steckler (2002) to ensure a theory- and evidence-based approach. As process measures used in research are seldom reported in manuscripts, most of the measures were newly developed with the IDEFICS study itself. The measures itself are added to the chapter to share these instruments with other researchers so that they can build on our measures to develop their own.
The development of instruments, the baseline data collection and the first follow-up work as part of the IDEFICS study (www.idefics.eu) were financially supported by the European Commission within the Sixth RTD Framework Programme Contract No. 016181 (FOOD). The most recent follow-up including the development of new instruments and the adaptation of previously used instruments was conducted in the framework of the I.Family study (www.ifamilystudy.eu) which was funded by the European Commission within the Seventh RTD Framework Programme Contract No. 266044 (KBBE 2010–14).
We thank all families for participating in the extensive examinations of the IDEFICS and I.Family studies. We are also grateful for the support from school boards, headmasters and communities.
We also thank Gianvincenzo Barba from the Institute of Food Sciences, National Research Council (Avellino, Italy) who unexpectedly passed away before this book was completed for his valuable contributions to the IDEFICS/I.Family studies.
