This paper illustrates an application of Efron's bootstrap to the repeated measures design. While this approach does not require parametric assumptions, it does utilize distributional information in the sample. By appropriately resampling from study data, the bootstrap may determine accurate sampling distributions for estimators, effects, or…

This response to the Baglin paper (1986) points out the fallacy in inferring that inappropriate scaling procedures cause apparent discrepancies between medians and means and between means calculated using different units. (LMO)

This package contains four FORTRAN 77 programs for Markov Model based learning experiments. One program estimates the likelihood of a one-stage learning model, another delivers estimates for a two-stage learning model. The third and fourth were designed for hypothesis testing the parameter differences between and within experimental conditions,…

This study was designed to (1) gather Australian data on the Toddler Temperament Scale (TTS), (2) assess age differences on temperament in the one- to three-year-old group; (3) assess the psychometric properties of the TTS; and (4) consider some issues of concurrent validity in the measurement of temperament and behavioral adjustment.

Presents Price's law, which states that half of the literature on a subject will be contributed by the square root of total number of authors publishing in that area, and assesses it against empirical evidence and simulated productivity distributions. The discussion covers this law's relation to Lotka's law and its empirical validity. (Author/CLB)

Employed confirmatory and exploratory factor analytic methods to test the hypothesis that Spielberger's revised four-factor model of anxiety was valid for characterizing the anxiety of Blacks. Administered the State-Trait Anxiety Inventory to 182 Black adults. Confirmed the state-trait assertion, but not the four-factor model of anxiety-present…

Within the purview of Title VII of the Civil Rights Act of 1964, legislation has specifically addressed testing practices. Reviews the historical perspective of employment testing, nonuniformity of lower court interpretations of Title VII, and Supreme Court decisions; and presents recommendations for administrators and legislators.

The construction of a comprehensive final examination over the basic medical sciences is described. Performance on the exam was a better predictor of NBME-I scores than GPA in basic science or MCAT scores and a better predictor of NBME-II scores than preclinical course performance and MCAT scores. (Author/RH)

Examined the relationships among measures designed to assess two important aspects of family functioning: cohesion and control. Included these measures: Family Adaptability and Cohesion Scales-II (FACES-II), Family Environment Scale (FES), family sculpture task, and social desirability scale. Found preliminary convergent and discriminant validity…

Describes demonstration by an interdisciplinary geriatric evaluation team that a newly described syndrome of hysterical pseudodementia in elderly patients often originates in developmental phenomena rather than in basic personality disturbances. Discusses team members' observations of clinical behavior which frequently differed from results of…

Three methods of estimating point-biserial correlation coefficient standard errors were compared: (1) assuming normality; (2) not assuming normality; and (3) bootstrapping. Although errors estimated assuming normality were biased, such estimates were less variable and easier to compute, suggesting that this might be the method of choice in some…

Students' performance on the Final Examination at Bristol Medical School was compared to their performance as assessed by in-course assessment. The overall continuous assessment score has been a major predictor of failure by the students in the final examination. It is argued that in the light of these findings, a major final examination is…

A description of the problems that occurred with attempts to conduct drug tests at the 1987 Pan American games leads to a discussion of the legal challenges to drug testing and the need to establish a clear, effective, and fair policy for drug tests of athletes. (CB)

Study determines that solutions derived by multiple group analysis and item-total correlation analysis were generally most interpretable from a psychological perspective. It was concluded that their application to test construction is preferred over Procrustean or confirmatory maximum likelihood approaches. (RB)

Offers a humorous look at the problem of assessment. (FL)
