In psychology and sociology, the Thurstone scale was the first formal technique to measure an attitude. It was developed by Louis Leon Thurstone in 1928, originally as a means of measuring attitudes towards religion. Today it is used to measure attitudes towards a wide variety of issues.
That is, the scale represents how heavy people perceive the objects to be based on the comparisons. Although Thurstone referred to it as a law, as stated above, in terms of modern psychometric theory the 'law' of comparative judgment is more aptly described as a measurement model. It represents a general theoretical model which, applied in a ...
The BTL model, the Thurstonian model as well as the Rasch model for measurement are all closely related and belong to the same class of stochastic transitivity. Thurstone used the method of pairwise comparisons as an approach to measuring perceived intensity of physical stimuli, attitudes, preferences, choices, and values.
The term attitude with the psychological meaning of an internal state of preparedness for action was not used until the 19th century. [3]: 2 The American Psychological Association (APA) defines attitude as "a relatively enduring and general evaluation of an object, person, group, issue, or concept on a dimension ranging from negative to positive.

Attitude towards an object are influenced not only by the characteristics of the object itself (cognitive aspect) but also by the context in which the object is encountered, a concept known as attitude-toward-situation. [5] The behavior is better predicted when both the attitude-toward-object and attitude-toward-situation are considered.
Bogardus Social Distance Scale and its variations remain the most popular measure of social distance. [5] [6] In questionnaires based on Bogardus' scale, respondents are typically asked members of which groups they would accept in particular relationships. For example, to check whether or not they would accept a member of each group as a ...
The Guttman scale is related to Rasch measurement; specifically, Rasch models bring the Guttman approach within a probabilistic framework. Constant sum scale – a respondent is given a constant sum of money, script, credits, or points and asked to allocate these to various items (example : If one had 100 Yen to spend on food products, how much ...
