Development of an implementation guide to facilitate the roll-out of early intervention services for psychosis.
Our aim was to develop an implementation guide that was informed by an analysis of context-specific barriers and enablers, behaviour change theory, as well as evidence about the effects of implementation interventions, for the establishment and scaling up of an early intervention model for psychosis (called Early Psychosis Prevention and Intervention Centre (EPPIC)).



We used a systematic approach involving four steps. First, the target behaviours of the EPPIC model for implementation were specified. Second, a consultation was undertaken to explore the barriers and enablers to undertaking these priority minimum standard clinical behaviours. Third, an implementation strategy that included a range of behaviour change techniques tailored to address the identified barriers was developed. Finally, a tool to assess whether those implementing the EPPIC model maintained fidelity to the implementation strategy was designed.



We identified a range of barriers that could act to dilute the core components of the EPPIC model and compromise its implementation. An implementation strategy using theory and evidence-based strategies for behaviour change was designed to address these barriers.



The process we used in the development of the implementation strategy provided a unique opportunity to consider the essential areas to cover, how to make information easily understandable and accessible while noting the complexity of issues involved in not only implementation, but also the scaling up of the EPPIC model for services.
