Developing and evaluating hand hygiene and hand cleansing interventions for the user: a perceptual control theory approach

Research Interests: Hand hygiene; hand-washing; infection control; perceptual control theory (PCT); health interventions and, public health.

Bio: I am a Senior Lecturer in Psychology at Middlesex University with a teaching and research background in social psychology. Lately my research interests have turned to the application of psychological theory to the multidisciplinary area of hand hygiene and hand washing.

My research investigates the purposes, perceptions and behaviours of people when they clean their hands. It applies the far-reaching fundamental insights of perceptual control theory (PCT) to frame the problem and uses it as a basis for developing an intervention to enhance hand washing efficacy. This is of particular contemporary relevance as hand hygiene forms part of our defences against established gastro-intestinal and respiratory tract infections as well as newly emerging conrona-viruses.

In the image above, the smooth patch on the back of the participant's hand is UV gel after an attempt at cleaning. It gives some idea of the problem!
