Some previous studies suggest that response times (RTs) on rating scale items can be informative about the content trait, but a more recent study suggests they may also be reflective of response styles. The latter result raises questions about the possible consideration of RTs for content trait estimation, as response styles are generally viewed…

Student evaluations of teaching are widely used to assess instructors and courses. Using a model-based approach and Bayesian methods, we examine how the direction of the scale, labels on scales, and the number of options affect the ratings. We conduct a within-participants experiment in which respondents evaluate instructors and lectures using…

Questionnaires routinely measure unipolar and bipolar constructs using rating scales. Such rating scales can offer odd numbers of points, meaning that they have explicit middle alternatives, or they can offer even numbers of points, omitting the middle alternative. By examining four types of questions in six national or regional telephone surveys,…

The influence of scale format on results was examined. Two Likert type formats, one with all choice points defined and one with only end-points defined, were administered. Each subject completed half the items in each format. Results indicated little difference between forms, nor did subjects indicate a format preference. (Author/DWH)

The goal of this study was to assess the relative merit of various ranges and types of response scales in terms of respondent satisfaction and comfort and the nature of the elicited information in a population of seventh grade students. Three versions of an attitudinal questionnaire, each containing the same items but employing a different…

Three rating scales--with all positive or all negative wording, or a mixture of both--were administered to 522 children in grades four through six. The results indicated that it was difficult for students to indicate agreement by disagreeing with a negative statement. This affected test validity. Author/GDC)

Several methodological problems (particularly the assumed bipolarity of scales, instructions regarding use of the midpoint, and concept-scale interaction) which may contribute to a lack of precision in the semantic differential technique were investigated. Results generally supported the use of the semantic differential. (Author/JKS)

To discover factors which contribute to a high response rate for questionnaire surveys, the preferences of 150 college teachers and teaching assistants were studied. Four different questionnaire formats using 34 common items were sent to the subjects: open-ended; Likert-type (five points, from "strong influence to return," to…

A questionnaire concerning attitudes toward the importance of communication skills and toward different modes of communication was administered to 290 incoming freshmen at the National Technical Institute for the Deaf. Students responded to one of two types of a 38-item questionnaire: a multiple choice, or Likert-type (strongly agree...strongly…
