Research Focus


The particular focus of this area of research which is led by Dr Gerry Molloy is on medication and treatment adherence across the lifespan. Adherence refers to the extent to which a person’s behaviour e.g. taking medication or following health advice, corresponds with agreed recommendations from a health care provider. Non-adherence has been recognised as a major global public health problem by the World Health Organization (2003). The research conducted by the MEDAL group includes both aspects of self-management of chronic illness in older adulthood e.g. adherence to cardiovascular medications and the use of preventive medications in early adulthood e.g. adherence to the oral contraceptive pill. Theory and methods from behavioural sciences are used to improve our understanding of the psychological and social processes in health, illness and healthcare.
