In psychology, ipsative questionnaires (/ ˈ ɪ p s ə t ɪ v /; from Latin: ipse, 'of the self') are those where the sum of scale scores from each respondent adds to a constant value. [1] Sometimes called a forced-choice scale , this measure contrasts Likert-type scales in which respondents score—often from 1 to 5—how much they agree with ...
The median raw score for each scale within this sample was assigned a BR score of 60, and BR scores of 75 and 85 were assigned to raw score values that corresponded to the base rates of presence and prominence within the sample, respectively, of the condition represented by each scale. Intermediate values were interpolated between the anchor ...
Likert scale data can, in principle, be used as a basis for obtaining interval level estimates on a continuum by applying the polytomous Rasch model, when data can be obtained that fit this model. In addition, the polytomous Rasch model permits testing of the hypothesis that the statements reflect increasing levels of an attitude or trait, as ...
Each item is weighted on a 0–3 interval scale. The global PSQI score is then calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality. Traditionally, the items from the PSQI have been summed to create a total score to measure overall sleep quality.
Higher scores are positively correlated with higher levels of anxiety. Its most current revision is Form Y and it is offered in more than 40 languages. [1] The STAI was developed by psychologists Charles Spielberger, R.L. Gorsuch, and R.E. Lushene. Their goal in creating the inventory was to create a set of questions that could be applied ...
For example, applications of measurement models in educational contexts often indicate that total scores have a fairly linear relationship with measurements across the range of an assessment. Thus, some argue that so long as the unknown interval difference between ordinal scale ranks is not too variable, interval scale statistics such as means ...

Total symptom severity is calculated by summing up all the individual item severity scores. For example, in the CAPS-IV scoring, to meet criteria for a symptom, the symptom must have an intensity score of 2 (on a scale or 0-4) or greater and a frequency score of 1 (on a scale of 0–4) or greater.
