This study uses the nominal response model to investigate the effects of extreme response styles. The Zung Self-Rating Anxiety Scale (SAS) is a commonly used scale for the identification of anxiety disorders. In some cases, the response options are not extreme, ranging from "A little of the time" to "Most of the time;" in other…

Psychologists have become increasingly interested in the intra-individual variability of psychological measures as a meaningful distinguishing characteristic of persons. Assessments of intra-individual variability are frequently based on the repeated administration of self-report rating scale instruments, and extreme response style (ERS) has the…

Heterogeneity in response styles can affect the conclusions drawn from rating scale data. In particular, biased estimates can be expected if one ignores a tendency to middle categories or to extreme categories. An adjacent categories model is proposed that simultaneously models the content-related effects and the heterogeneity in response styles.…

This article investigates the effect of the rural-urban divide on mean response styles (RSs) and their relationships with the sociodemographic characteristics of the respondents. It uses the Representative Indicator Response Style Means and Covariance Structure (RIRSMACS) method and data from Guyana--a developing country in the Caribbean. The…

Extreme response style (ERS) is a systematic tendency for a person to endorse extreme options (e.g., strongly disagree, strongly agree) on Likert-type or rating-scale items. In this study, we develop a new class of item response theory (IRT) models to account for ERS so that the target latent trait is free from the response style and the tendency…

Response styles, the tendency to respond to Likert-type items irrespective of content, are a widely known threat to the reliability and validity of self-report measures. However, it is still debated how to measure and control for response styles such as extreme responding. Recently, multiprocess item response theory models have been proposed that…

Most faculty developers have a wide variety of rating scales that fly across their desk tops as their incremental program activities unfold during the academic year. The primary issue for this column is: What is the quality of those ratings used for decisions about people and programs? When students, faculty, and administrators rate a program or…

The comparative format used in ranking and paired comparisons tasks can significantly reduce the impact of uniform response biases typically associated with rating scales. Thurstone's (1927, 1931) model provides a powerful framework for modeling comparative data such as paired comparisons and rankings. Although Thurstonian models are generally…

A multidimensional item response theory model that accounts for response style factors is presented. The model, a multidimensional extension of Bock's nominal response model, is shown to allow for the study and control of response style effects in ordered rating scale data so as to reduce bias in measurement of the intended trait. In the current…

Purpose: The purpose of this paper is to investigate a possible favourable response pattern on scaled forms used as a means of evaluating training courses. Design/methodology/approach: In part one of the study evaluation forms were examined referring to courses were completed by 879 students attending 15 university level courses and 531 students…

The goal of this study is to investigate how features of a rating scale developed for English-speaking populations interact with Spanish-speaking respondents' response styles and functional categories of judgment. A sample of 400 Spanish-speaking students took a translated scale and a scaling task developed to measure response sets and functional…

Results of this study indicate that VPI acquiescence scale scores are suspect as indicators of the response style of acquiescence. (Author)

The "Complementary Sheet" is applicable to Wechsler Scales: WBI, WBII, WISC, and WAIS. It consists of two sides of one sheet and has space for data collection of Picture Arrangement, Block Design, Object Assembly, and Digit Symbol or Coding. It lends itself well to an analysis of the means, not just the end result, of an examinee's…

Although most scaling formats include an intermediate or neutral response category, little research has been devoted to the analysis of the meaning respondents attach to this category. Results obtained from ten different scales, across two types of item formats support the traditional method of scoring the ? answer.

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)
