The Marketing Scales website is a gold mine of information. It is the only source that helps me understand the psychometric quality of the instruments used in past research. I recommend that researchers bookmark this site . . . they will be back!
evaluation
In this scale, four, seven-point semantic differentials evaluate how positive or negative a person’s attitude is toward a brand name. A three-item version is also described.
The desirability of an object is measured with four brief statements and a seven-point Likert-scale. The scale is “general” in the sense that the statements are amenable for use with a wide variety of objects.
A person’s chronic motivation to critically evaluate alternatives in order to improve the quality of decisions that are made is measured with twelve, six-point Likert-type items.
The scale has three, seven-point Likert-type items that measure the degree to which a person redefined his/her role in a relationship due to some event. The event is not stated in the items themselves but should be made clear to respondents in the context of the study or the instructions.
Using three, 10 point questions, this scale measures the degree to which a person thought about how he/she was being evaluated by a particular person with whom he/she had interacted. In this case, “evaluation” is meant more in the sense of being “sized-up” or judged rather than formal testing or professional diagnosis.
The tendency to worry about what other people think of oneself is measured with 12, seven-point items.
The extent to which a person relied on his/her emotions and intuition when evaluating an advertisement is measured using three, seven-point Likert-type items.
A person’s attitude about the effect of a product on the environment and the propriety of buying the product is measured with four, seven-point items. This product attribute is sometimes referred to as “greenness” or “environmental friendliness” meaning that it is either good for the environment or, at least, has less of a negative impact than conventional alternatives.
A consumer’s nutrition-focused attitude about a food product is measured using five, seven-point Likert-type items. Because of the limitations of one of the items, a four item version is also described that can be used with a wider variety of foods.
How much a person likes a beverage based on the way it looks and tastes is measured with four, seven-point items.
