Ian Tancred. Heron created the six-stage category intervention model, which is a useful aide between patient and carer. These six-stages were further subdivided into two interventions these being authoritative (prescriptive, informative, confronting) and facilitative (cathartic, catalytic and supportive). Authoritative is whereby the helper takes control of the situation and provides direction to the patient by either providing information, challenges or suggestions about the care they need. An example of authoritative care would be asking the patient to look left, right, up and down when examining their injured eye. Facilitative care occurs when the carer shows their support and understanding of an individual's decisions, ideas, and emotions.
