In this paper we present an exemplar of the initial theory-building phase of Theory-driven Evaluation (TDE) for the PARTNERS2 project, a collaborative care intervention for people with experience of psychosis in England. Initial theory-building involved analysis of literature, interviews with key leaders, and focus groups with service users. The initial programme theory (IPT) was developed from these sources in an iterative process between researchers and stakeholders (service users, practitioners, commissioners) involving four activities: articulation of 442 explanatory statements systematically developed using realist methods; debate and consensus; communication; interrogation. We refute two criticisms of TDE of complex interventions. We demonstrate how the process of initial theory-building made a meaningful contribution to our complex intervention in five ways. Although time consuming, it allowed us to develop an internally coherent and well documented intervention. This study and the lessons learnt provide a detailed resource for other researchers wishing to build theory for TDE.
