On the basis of a distinction between test content and method of testing, the present study examined several conceptually and practically important effects relating race, reading comprehension, method of assessment, face validity perceptions, and performance on a situational judgement test using a sample of 241 psychology undergraduates (113 Blacks and 128(More)
The relationships among race, face validity perceptions, test-taking motivation, and test performance on a cognitive ability test were examined. Undergraduates completed 2 parallel cognitive ability tests and a test reactions measure. Results showed that test-taking motivation was related positively to subsequent performance on a parallel test even after(More)
Intraindividual change over time is the essence of the change phenomenon hypothesized to occur in the individual newcomer adaptation process. Many important adaptation questions cannot be answered without an adequate conceptualization and assessment of intraindividual change. Using a latent growth modeling approach to data collected from 146 doctoral(More)

This article demonstrates how Sörbom's (1974) mean and covariance structure analysis (MACS) model can be used to detect uniform and non-uniform differential item functioning (DIF) on polytomous ordered response items that are assumed to approximate a continuous scale. Using item responses from 773 civil service employees, the MACS model was applied to three(More)

The relationships between examinees' racial subgroup membership and their perceptions of the predictive validity of a widely used personality test (NEO Five Factor Inventory; P. T. Costa & R. R. McCrae, 1992) and a widely used cognitive ability test (Wonderlic Personnel Test; E. F. Wonderlic, 1984) were examined. Results from 241 undergraduates showed that(More)
To understand the nature of test reactions and their relationship to test performance, the relationships among belief in tests, pretest reactions, test performance, and posttest reactions were modeled for cognitive ability and personality tests. Results from structural equation models that were fitted to responses from 197 undergraduate examinees supported(More)
Multivariate latent growth modeling was used to conceptualize and analyze intraindividual changes in children's social skills and interindividual differences in these changes in home and school settings. Parent and teacher ratings assessing children's social skills at home and school settings, respectively, were obtained for a sample of 378 children at 4(More)
Objective: To validate existing skinfold thickness predicting equations and to develop an equation for estimating body fat composition in obese Chinese children. Design: Cross-sectional study. Subjects: One hundred and thirty-eight Chinese obese children, 37 girls and 101 boys with mean age and body mass index (BMI) of 11.9 years (SD 2.7) and 29.7 Kg/m (SD(More)
Children with autism spectrum disorder (ASD) were reported to have higher rates of unmet dental needs and behavioural problems that leading to dental care or oral hygiene problems. With the lack of dental services for preschool children in Hong Kong, the severity of dental problems in this group of children has not been documented locally. The aim of this(More)
Longitudinal data were used to examine the effects of parental employment status and school climate on children's academic and social development. Hierarchical regression, analyses of covariance, and latent growth modeling were used to assess various aspects of change as a function of work status and school climate with family income and education as(More)
