The Health Utilities Index (HUI) is a rating scale used to measure general health status and health-related quality of life (HRQoL). HUI questionnaires are designed to map onto two classification systems, HUI-2 and HUI-3, capable of measuring 24,000 and 972,000 unique health states, respectively.
Each question is scored on a scale of 0–5 with the first statement being zero and indicating the least amount of disability and the last statement is scored 5 indicating most severe disability. [2] The scores for all questions answered are summed, then multiplied by two to obtain the index (range 0 to 100).
The test asks 51 questions in all with a number being red herrings to test for people over-rating themselves. It has been proposed that this is useful for spotting malingerers and hypochondriacs , however its intention in the original research proposal for LUNSERS was to demonstrate the robustness and reliability of self-reporting.
The SLUMS is scored on a scale of 1 to 30, with higher scores being associated with greater functional ability, and lower scores associated with greater cognitive impairment. [5] Scoring is dependent on an individual's education level, with higher scores expected for individuals who have received a high school education.
A test score is a piece of information, usually a number, that conveys the performance of an examinee on a test. One formal definition is that it is "a summary of the evidence contained in an examinee's responses to the items of a test that are related to the construct or constructs being measured." [1]
The test produces both a pattern of scores as well as a variety of composite scores, which is a plus. This allows analyzing of both individual sections as well as the overall test. In fact, the concept of combining various subtests to form a composite score is such an important idea that it has become one of the main features in the 2003 fifth ...
A score of 0 on a question would indicate no function while a score of 4 would indicate full function. [4] [5] This scale has been useful for doctors in diagnosing patients, measuring disease progression and also for researchers when selecting patients for a study and measuring the potential effects of a clinical trial. [4] [6]
There are score ranges that define low, moderate and high levels of each scale based on the 0-6 scoring. The 7-level frequency scale for all MBI scales is as follows: Never (0) A few times a year or less (1) Once a month or less (2) A few times a month (3) Once a week (4) A few times a week (5) Every day (6)
