Health Psychology Research (HPR) Ltd. was incorporated in 2003 by Professor Clare Bradley to manage the licensing of her questionnaires designed, developed and used by her research unit (the Health Psychology Research Unit – HPRU), which was then based at Royal Holloway, University of London. In 2020, Clare Bradley became Professor Emerita of Health Psychology at Royal Holloway and merged the activities of her HPRU and HPR Ltd.

The company continues to license questionnaires for use by researchers and clinicians in clinical trials, as well as other research studies, routine audit and clinical practice. In addition, HPR manages the linguistic validation of Clare Bradley’s questionnaires for use in different countries and engages in design and development of new instruments. 

HPR Ltd is based in offices close to the Royal Holloway campus, in Egham. Royal Holloway is located about 20 miles west of Central London and about 5 miles from Heathrow Airport.
