The psychological effects of Hurricane Andrew on ethnic minority and Caucasian children and adolescents
The impact of Hurricane Andrew on 212 African American, Caucasian, and Hispanic elementary and middle school children was examined at 6 months postdisaster. Using self-report instruments, this case study examined the predictive utility of several hypothesized mediators of children's reactions to disaster. Results showed higher levels of intrusive symptomatology for girls and for elementary school children as compared with their middle school coun…
Comparison of Two Indices of Answer Copying and Development of a Spliced Index
Two indices of answer copying, one using only identical wrong responses and the other using both right and wrong, were compared using naturally occurring test responses (no simulation of copying). Each index pointed to the existence of about the same number of exannnee pairs who had copied. However, index B implicated more higher scoring pairs that he g2 index, which, in turn, implicated more lower scoring pairs. An adaptation Of g2 using only wr…
Allowing Students a Choice of Items on Objective Examinations
Measurement experts often advise against giving students an option of selecting which items on a test they choose to answer. A review of the related literature revealed that this caveat refers primarily to essay examinations. It was the purpose of this research to investigate the effects of permitting students the prerogative of selecting a proportion of the items on an objective test which they wished to exclude from the calculation of a grade. …
Over consumption of fat by college students
College students (416) in an introductory nutrition class were surveyed to determine how college students categorize foods and to establish the relationships between fat intake (3‐day diet record), everyday food choices and fat practices (frequency survey), and fast‐food use (attendance and food consumption). Factor analysis of everyday food choices resulted in five groupings, three high‐fat and two low‐fat. Males averaged 84 g fat/day (range 26–…
College Students' Nutrition Information Networks
Nutrition information networks accessible to or being accessed by college students were studied. Data were collected on the types of networks, the extent of their use, and the relationship of use tofood behavior. Undergraduate students (179 men, 300 women) in an introductory nutrition class rated their perceived use of nutrition information networks; provided frequency‐of‐use responses to a survey offood choicesfat practices, andfast‐food practic…
Aera Opinions on Women's Equity Issues
An opinion survey on sex-equity concerns was conducted for a sample of AERA members. Results indicated strong male-female differences on issues related to professional employment, such as reverse bias and the extent to which men are favored over women in work assignments. In contrast, large proportions of men and women supported statements on reduction in use of sex-specific references and the importance of sex-equity research. Women's responses …
Elimination of Bias in Test Scores
This paper demonstrates that correlation between bias components of test scores and unbiased observed scores is an effective predictor of changes in reliability and validity resulting from elimination of bias. Plausible assumptions about the value of this correlation and the sizes of related variance components yield the conclusion that reduction in reliability and validity is a possible outcome. This reduction could result in marginally valid or…
A Factor-Analytic Study of Mathematics Anxiety
Responses from 491 university students largely from non-technical majors were obtained for 21 personality scales, five scales reflecting attitudes toward mathematics and six personal characteristics. Factor analysis of the personality and mathematics attitude variables revealed that scores on four of the five mathematics attitude scales (one of which was entitled Math Anxiety) were strongly related to a single, underlying attitude toward mathemat…
Willingness to Answer Multiple-Choice Questions as Manifested Both in Genuine and in Nonsense Items
A formal description of partial knowledge, ability, and willingness to answer multiple-choice items put forward by Hutchinson (1977, 1980) makes predictions about response behavior on items for which none of the stated alternatives is correct. Cross and Frary (1977) obtained data on subjects' responses under these conditions. Hutchinson's theory is shown to account for a moderate proportion of the variation between subjects in the number of nonse…
Empirical Choice Weighting Under "Guess" and "Do Not Guess" Directions
This study investigated reliability and validity of scores resulting from empirical choice-weighting under two conditions: (1) examinees were told not to guess when unable to eliminate any choice and (2) they were told their scores would be the number of right responses. Unlike other choice-weighting studies which have reported disappointing results under one or the other of these two conditions, the present study used a predictor and criterion w…
