Health psychology examines the role of psychological factors in the cause, progression and consequences of health and illness. The aims of health psychology can be categorised into (1) understanding, explaining, developing and testing theory, and (2) putting this theory into practice. CERVIVA is using health psychology to help understand women’s knowledge of, and attitudes towards, cervical screening and HPV. We are also using health psychology to investigate the psychological impact of cervical screening and follow-up of abnormal cervical cytology. The ultimate aim of this research is to improve cervical screening experiences for women.
