Critically examining common statistical approaches and their strengths and weaknesses is an important step in advancing recreation and leisure sciences. To continue this critical examination and to inform methodological decision making, this study compared three approaches to determine how alternative approaches may result in contradictory…

Studies reporting sociometric assessments based on nominations have been characterized by important methodological inconsistencies when conducted in the middle school context. The purpose of this study was to examine (1) the possibility of a response bias when participants are provided with a long roster sorted alphabetically, (2) the impact of…

Three computer simulations were conducted to show that very high aggregate predictive validity coefficients can occur when the across-case variability in absolute score stability occurring in both the predictor and criterion matrices is quite small. In light of the increase in internal consistency reliability achieved by the method of aggregation…

Patients were classified into categories using Spitzer and Endicott's computer program for diagnosis. Analyses of variance using single and grouped scales and discriminant analyses predicting category membership suggested that narrow band categorization is better predicted by the Minnesota Multiphasic Personality Inventory than is broad band…

Concludes that there is no evidence for differential validity in the Minnesota Multiphasic Personality Inventory (MMPI) between racial subgroups and that black norms for the MMPI are premature. Criticism of these findings is also presented. (Author/BEF)

Prediction of success in a special program often guides program participant selection and treatment. If the statistical analysis used to develop such predictions is based on the special selectivity built into the program, the predictions can be misleading and the validation tests uninformative. Federal district court pretrial release data is used…

A study by Malcolm R. Parks reported in "Communication Monographs" called into question the cross-situational validity of the Personal Report of Communication Apprehension (PRCA). Park's study, however, is flawed in many ways. He does not provide an adequate definition of "situation." Both the type of factor analysis he chose…

The conventional paradigm for testing expectancy theory predictions of work behavior has been to correlate expectancy-value reports with concurrent measures of motivation and performance. Although this static, two-variable approach has typically yielded statistically significant results, correlations have not been sizable. This study, using a…

Meta-analysis of research on a topic may exclude reports that do not present their results in a statistical form amendable to summarizing procedures used. This article illustrates how researchers can consider this aspect in computing statistics from their data. An illustration of how that can sometimes be done is presented. (Author/JAZ)

Used discriminant analysis in an attempt to differentiate nonviolent and violent families as a function of variables said to be significant predictors of family violence in a decade review by Gelles. Results indicate that the predictor variables fail to account consistently for differences among the groups. (Author)

High rates of learner attrition from courses continue to plague distance education institutions. As educational researchers continue to examine the attrition/completion issue, many measurement problems emerge. Focusing on Athabasca University, Alberta, this paper, part of a series produced by Project REDEAL (Research and Evaluation of Distance…

Studied predictability of therapeutic outcome of an alcoholism treatment program. Data analyzed by a mathematically oriented linear regression approach and by a clinically oriented retrospective parametric approach showed different predictors. Suggested that the parametric clinical approach be used to explain why therapy succeeded or failed.…

Reviews issues of reliability (especially test-retest reliability) in newborn assessment, discusses predictive models based on newborn assessment, and presents information on modifications of the Brazelton Neonatal Behavioral Assessment Scale which may help in pursuing fruitful questions involving prediction of development. (Author/BH)

Discusses the role and limitations of the Brazelton Neonatal Behavioral Assessment Scale in the continuing effort to construct an adequate account of infant development. (BH)

A total population study of 4,797 six-year-old children attending the public preschools in the city of Gothenburg, Sweden was conducted in order to investigate the problematic area of perceptual, motor and attentional deficits in preschool children. A questionnaire with 34 questions about minimal brain dysfunction-related problems was distributed…
