GLASGOW COMA SCALE

Medical Dictionary

A method developed by two doctors in Glasgow that is used to assess the depth of COMA or unconsciousness su?ered by an individual. The scale is split into three groups – eye opening, motor response, and verbal response – with the level of activity within each group given a score. A person’s total score is the sum of the numbers scored in each group, and this provides a reasonably objective assessment of the patient’s coma state – particularly useful when monitoring people who have su?ered a head injury. (See also PERSISTENT VEGETATIVE STATE (PVS).)... Medical Dictionary

MEASUREMENT SCALE

Community Health

The complete range of possible values for a measurement (e.g. the set of possible responses to a question, the physically possible range for a set of body weights). Measurement scales are sometimes classified into five major types, according to the quantitative character of the scale: dichotomous scale: One that arranges items into either of two mutually exclusive categories. nominal scale: Classification into unordered qualitative categories, such as race, religion, and country of birth, as measurements of individual attributes are purely nominal scales, as there is no inherent order to their categories. ordinal scale: Classification into ordered qualitative categories, such as social class, where the values have a distinct order, but their categories are qualitative in that there is no natural (numerical) distance between their possible values. interval scale: An (equal) interval involving assignment of values with a natural distance between them, so that a particular distance (interval) between two values in one region of the scale meaningfully represents the same distance between two values in another region of the scale. An example is date of birth. ratio scale: A ratio is an interval scale with a true zero point, so that ratios between values are meaningfully defined. Examples are weight, height, blood count and income, as in each case it is meaningful to speak of one value as being so many times greater or less than another.... Community Health
