Conceptualising the functional role of mental health consultation–liaison nurse in multi-morbidity, using Peplau's nursing theory.

This paper examines the mental health consultation–liaison nursing (MHCLN) role and links this to the interpersonal relations theory of nurse theorist Hildegard Peplau. The paper argues that, as mental health nursing care around the world is increasingly focused upon meaningful therapeutic engagement, the role of the MHCLN is important in helping to reduce distressing symptoms, reduce the stigma for seeking help for mental health problems and enhancing mental health literacy among generalist nurses. The paper presents a small case exemplar to demonstrate interpersonal relations theory as an engagement process, providing patients with methodologies which allow them to work through the internal dissonance that exists in relation to their adjustment to changes in life roles precipitated by physical illness. This dissonance can be seen in the emergence of anxiety, depression and abnormal/psychogenic illness behaviours. This paper concludes arguing for considerable effort being given to the nurse–patient relationship that allows for the patient having freedom to use strategies that may help resolve the dissonance that exists.
