Who is Being Assessed or Evaluated?:
Self-report (e.g., survey, questionnaire, self-rating)
Notes for Data Sources:
In general, the survey is designed for persons 18 years and older. In the Brazier validation study, the survey was sent to 1980 patients, randomly selected from two general practice lists in Great Britain. For test-re-test reliability, the survey was re-sent to a subset of 250 patients randomly selected from the same lists. The demographics of the sample largely replicated that of Britain's general household survey.

The Brazier study in 1992 reported results from a mailed survey. Currently, as supported by the distributor, Optum, Inc., the survey can be administered in a variety of modalities, in-person paper and pencil, interview, online and over mobile devices.
Scoring was not discussed in the Brazier validation study. As supported by Optum, the instrument's scores are norm-based: a score of 50 = average. Two summary measures are derived: a physical component summary (PCS) and a mental component summary (MCS). (See link to the instrument manual, above.)
English; as supported by Optum, the survey has been widely translated and in available in 170 languages.
Notes on Access:
