Having viewed some of the highly edited videotaped material of Terri Schiavo and having seen other patients in a persistent vegetative state, I am not surprised that family members and others unfamiliar with this condition would interpret some of her apparent alertness and movement as meaningful.
A Likert Scale is a type of psychometric scale frequently used in psychology questionnaires. It was developed by and named after organizational psychologist Rensis Likert. Self-report inventories are one of the most widely used tools in psychological research.
Getting even helps. Most frequently, Likert scales consist of five items (as in the example above), and seven-item scales are also quite common. The mid-range of the scale is a âneutralâ option, such as âno opinionâ, âneither agree nor disagreeâ, ânot sureâ or some phrase to that effect.
