This note describes the methodology behind the design of the REFORMED Survey questionnaires. The Survey constitutes one of the main pillars of REFORMED RS2 which is aimed at exploring the intricate relationship between SAWA policies, contextual contingencies and policy enactment dynamics. The aim of this note is essentially twofold. On the one hand, it provides detailed information on the key concepts used in RS2 as well as the theoretical underpinnings and content of the questionnaires. On the other hand, it presents a detailed overview of the methodological steps followed to conceive and develop them. The information contained in this note is relevant for those researchers who want to use the data collected through the REFORMED Survey. It also provides useful methodological insights that can be valuable for those who want to undertake similar research endeavours.
