The semantic differential scale (Osgood, Suci and Tannenbaum, 1957) is a multi – dimensional measure between two bipolar adjectives; respondents must select a point along this scale that represents the direction or intensity of their feelings. (For an excellent discussion of semantic differential scales see Heise, 1970.) The semantic differential scale (see Example 16.5) is used to assess the subjective meaning to a concept. The data is analysed using factor analysis, which involves a large number of correlations between variables. This measure is designed to identify an individual’s beliefs about a concept or object over three dimensions: activity, the extent to which the object or concept is associated with action: potency, the strength or importance of the object or concept: and evaluation, the overall positive meaning associated with the object or concept (Heise, 1970).
