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…

Many have elaborated on the potential of virtual reality (VR) in learning. This article attempts at organizing the literature in this issue in order to better identify indicators that can account for future valid trends, and seeks to bring to attention how authors who wrote about the future of VR in education confused futures' terms and produced…

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…

R. D. Howell, E. Breivik, and J. B. Wilcox (2007) have argued that causal (formative) indicators are inherently subject to interpretational confounding. That is, they have argued that using causal (formative) indicators leads the empirical meaning of a latent variable to be other than that assigned to it by a researcher. Their critique of causal…

To determine if the observed correlation between two variables can be "explained" by a third variable, a significance test on the partial correlation coefficient is often used. This can be misleading when the third variable is measured with error. This article shows how the problem can be partially overcome. (Author/BW)

In their article, "Disconfirmation of the Predictive Validity of the Self-Appraisal Questionnaire in a Sample of High-Risk Drug Offenders," criminologists Mitchell and MacKenzie (2006) purported to evaluate psychometric properties of the Self-Appraisal Questionnaire (SAQ), the first self-report risk/need measure estimating violent and nonviolent…

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…

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)

Studies reporting predictions from assessments of infant recognition memory to later developmental performance and IQ are critiqued. Inelegancies in design, procedure, and analyses are noted. While this approach may have potential, its utility for practical or clinical purposes is still not demonstrated. (Author/RD)

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)
