To evaluate the implementation of a general MECC training and bespoke MECC training delivered to staff at CNTW (Cumbria, Northumberland, Tyne and Wear NHS Foundation Trust). The training program, which is designed to support weight management (A Weight Off Your Mind, weight management health program), is designed to improve staff confidence in discussing physical activity, healthy eating and behaviour change with service users. This pragmatic process evaluation (defined as, the process of evaluation of a program currently implemented in routine but lacking systematic development and evaluation) is designed to evaluate three work packages using qualitative research methods. The project will explore; perceptions, capabilities, opportunities, motivations (COM-B model) and experiences of healthcare professionals (HCPs) delivering MECC at CNTW, assess service users’ experiences of receiving MECC, assess the theory, techniques and content of MECC as delivered by trained health professionals at CNTW and to understand if this is delivered with fidelity, and to identify data collections and management information systems for MECC at CNTW.
