AIMS -The objective of this study was to identify factors that either promote or hinder implementation of a multicomponent Responsible Beverage Service programme in Swedish municipalities. DESIGN -Forty semi-structured interviews were conducted in six municipalities and directed content analysis, guided by the Consolidated Framework for Implementation Research (CFIR), was performed. RESULTS -The CFIR framework was useful as an underlying theoretical model in this study. Importance of the following factors, described in the five domains of CFIR, was empirically supported in this study: local needs, evidence strength and advantages of the intervention, costs and available resources, clear goals, evaluation and feedback, access to knowledge and information, clear role definitions and cooperation, and enthusiastic key persons with high confidence in the effectiveness of the intervention. Hindering factors listed by the informants were lack of enthusiasm and opportunities to specialise, low degree of self-efficacy, unengaged decision-makers, complexities of the programme, and a top-down approach. CONCLUSIONS -This study indicates that previously identified factors shown to promote and hinder implementation processes are also valid in the context of multicomponent community action programmes like RBS. Suggestions on how to elude some of the hindering factors are proposed, e.g. to develop long-time financial plans, to provide better information about the RBS program in full, and to stress the importance of collaboration between representatives from the municipalities, police authorities and owners of on-licenced premises.
