Intervention development is the crucial first step before formal feasibility and pilot testing, in preparation for conducting a large-scale definitive trial or observational study. It is increasingly recognized that careful attention to the methods used in development will increase the chance of interventions being effective within trials, and being adopted widely in the real world. However, this initial phase is seldom reported in detail and may overlap with assessment of acceptability and feasibility.
This exciting collection covers the systematic and rigorous processes involved when developing complex interventions. It will provide a focus for discussion, for researchers to learn from each other and to encourage scientific rigor in reporting the early phases of complex intervention design.
