With many individuals living with diabetes failing to make the necessary behaviour change to optimise glycaemic control1 it is imperative that staff involved in their care have the skills required to guide them in this respect. The COM-B assists in this regard as it provides a behaviour-change model based on scientific evidence and theory in a practical and accessible format, which enables non-specialists to design and implement behaviour-change interventions. This paper reports a case of psychological assessment, formulation and intervention in a patient with type 1 diabetes mellitus associated anxiety and sub-optimal diabetes management. It highlights: (1) the importance of a bio-psychological approach to assessment and formulation; (2) the value of involving the patient in their care from the outset; and (3) the ease at which the COM-B can be routinely applied in clinical settings.
