Velicer (1978) defines suppression situations in terms of the relations between part correlation and zero order validity. Conger (1974) defines suppressor in terms of regression weights. The present work clarifies the difference between the two approaches: Velicer's suppressor circumscribes only a subset of the suppression situations as defined by…

This paper presents formulas that can be used to approach the problem of nonresponse in survey research. (Author/AL)

A formal framework is presented for determining which of the distractors of multiple-choice test items has a small probability of being chosen by a typical examinee. The framework is based on a procedure similar to an indifference zone formulation of a ranking and election problem. (Author/BW)

The proportion of agreement, G, and kappa indexes are shown to differ in how they correct for chance agreements between two observers. On the basis of the findings, it is suggested that no single agreement index is appropriate for all sets of data. (Author/BW)

Student self-selection in deciding to repeat a test was examined by contrasting the test performance of students taking the Scholastic Aptitude Test (SAT) as juniors and again as seniors with the test performance of students taking the SAT only once as juniors. Results suggest there is self-selection in test repetition. (Author/GK)

Intransitives in observers' preference judgements for multidimensional natural landscape scenes are examined. Thurstone's Law of Comparative Judgement (LCJ) psychophysical scaling routine is used to scale landscape preference. Both the method of Rank Ordering (RO) and the method of Paired Comparisons (PC) are used to gather the raw data necessary…

This study provides support for the hypothesized effect of leniency on the discriminant validity of grouped questionnaire items. It was found that controlling for leniency resulted in a slight decrement in convergent validity but that discriminant validity was substantially improved. Implications for questionnaire validity and further research are…

The empirical evidence does not support the prevailing conventional wisdom that it is advisable to mix positively and negatively worded items in psychological measures to counteract acquiescence response bias. An experiment, evaluating subjects' ability to respond accurately to both positive and reversed items on a questionnaire, analyzed post-hoc…

Four different groups of respondents completed a set of simulation exercises intended to reflect lawyering skills involved in client interviews. Results suggest the appropriateness of simulation exercises as measures of clinical skills in legal education and the effectiveness of clinical programs in promoting development of such skills in law…

This study was designed to determine whether an unweighted linear combination of community college students' scores on standardized achievement tests and a measure of motivational constructs derived from Vroom's expectance theory model of motivation was predictive of academic success (grade point average earned during one quarter of an academic…

This study was designed to identify those females who are predicted to fall substantially below their male counterparts in mathematical participation and performance (female potential underachievers) and who are most in need of intervention procedures early in their college career. (Author/CE)

For 235 ninth-grade students, intercorrelations of Guilford's structure-of-intellect (SOI) tests and of three measures of critical thinking were factor analyzed. The study reveals the viability of using SOI constructs involving cognition and evaluation of semantic content as likely explanatory components of critical thinking. (Author/AL)

The Maslach Burnout Inventory (MBI) was designed to assess the frequency and intensity of perceived burnout among persons in the helping professions in general. Analyzing emotional exhaustion, personal accomplishment, and depersonalization (with depersonalization separated into job related and student related factors), this paper gives…

This study attempts to obtain evidence of the construct validity of pupil ability tests hypothesized to represent orientation to right, left, or integrated hemispheric function, and of teacher observation subscales intended to reveal behaviors in school setting that were hypothesized to portray preference for right or left brain function.

The distinctiveness of the subscale structure of an attitude instrument, the Test of Science-Related Attitudes (TOSRA), was examined. Factor analysis of the item correlation matrix obtained from student responses suggested that the seven subscales of the test were not distinct. (Author/GK)
