The Health Psychology Research Group (HPR) is based in the Department of Psychology at Royal Holloway, University of London in Egham, Surrey, in the United Kingdom. The campus is about 20 miles west of Central London and about 5 miles from Heathrow Airport.

Health Psychology Research Ltd. is an incorporated company which was set up to manage Professor Clare Bradley's questionnaires, draw up Licence Agreements and deal with all the legal and accounting administration involved. It is duly authorised to sub-license Prof. Bradley's questionnaires on her behalf. It is important to have a Licence Agreement before using any of the questionnaires. Please see Licensing Procedure for more information.

HPR Ltd. specialises in patient-reported outcome measurements in health-related research, and associated consultancy.

We recognise the importance of individuals’ perspectives of health and quality of life, so we focus on the development of methods to elicit and take account of individual views and experiences of chronic medical conditions. Headed by Professor Clare Bradley, the HPR researchers are pioneers in the development of questionnaires for patients with various chronic medical conditions including:

• endocrine disorders such as diabetes and hypothyroidism
• complications of diabetes including renal failure and retinopathy
• other eye conditions causing major sight loss, including macular disease
• viral infections such as HIV and herpes virus

Questionnaires have been designed to measure

• patient reported outcomes such as satisfaction with treatment, quality of life and well-being 
• beliefs and cognitions including locus of control and knowledge measures.

Using this web site, you will be able to view and download samples of questionnaires in all the languages in which they are currently available. These samples have been reduced to the introduction and first two questions so that you can easily check on the availability and accuracy of any language version in which you are interested. Full “For Information” copies can be obtained from HPR, if you need them for IRB submissions or inclusion in a study protocol. Each translation has undergone extensive linguistic validation work. Unless otherwise specified, linguistic validation includes forward and back translation and detailed pilot testing with clinicians and patients, to produce questionnaires that are linguistically accurate and culturally appropriate for each language and country. Every effort has been made to achieve semantic equivalence across languages/countries, as well as making the translations as colloquial as possible without sacrificing accuracy and equivalence.
