Self- (15Q) or Interviewer- (40Q) Administered?
|The Health Utilities Index (HUIR) measurement systems are a family of generic health status and health-related quality of life (HRQL) measures. This 'family' of measures includes the HUI Mark 1, HUI Mark 2, and HUI Mark 3, or more commonly referred to as the HUI1, HUI2, and HUI3. Although HUI1 is still used, HUI2 and HUI3 are much more frequently used in both clinical and population health studies and it is these 2 instruments that are the focus of this note.
Applications of the HUI require that data be collected to classify the health status of each subject at a point in time and to that end a variety of questionnaires and related procedure manuals have been developed and are available to facilitate the application of the HUI systems. Self-complete and interviewer-administered versions are available in both self-assessment and proxy-assessment formats. For each of these standard administration formats there are standard algorithms for converting responses into health attribute levels and single- & multi-attribute health utility scores.

|Questionnaire language availability - *NOTE: There are 8 'standard' HUI questionnaires possible per language in both Self-Administered (15Q) and Interviewer-Administered (40Q) formats. Standard questionnaires depend on 'Self- or Proxy Assessment' and 1 of 4 Recall Periods ('Usual health', 'during the past 4-weeks', '...2-weeks', '...1-week').
