The purpose of this article is to clarify the discrepancy in the use of "queer" as a sexual identity classification in education survey research. This study extends the work completed by Dugan and Yurman (2011), who empirically demonstrated problems with treating LGB students as a homogenous population through collapsing all respondents…

Research on perceptual and cognitive capacities of the newborn has revealed that state variables typically interfere with or override the neonate's attentional and stimulus processing tendencies. This finding argues for the power of early state variables as behavioral determinants and, further, that neonatal state measures might provide good…

Obesity in children is a problem both insidious and acute. Childhood obesity has been indicated as a forerunner of adult obesity; it is also an immediate problem for the child. Given the lack of evidence for long term maintenance of any weight loss, this paper investigates the etiology of the disorder as a prelude to prevention. Upon review of the…

Previous research linking life events and psychological well being may have been biased by traditional retrospective designs. To eliminate retrospective bias, a prospective design was used in which events were measured before the criterion had occurred. Subjects were 209 male and 159 female participants in the Augmented Baltimore Longitudinal…

This paper reviews evidence that characteristics of the perceptually fluent speech of stutterers change as a function of a number of variables and that, because these variables are difficult to fully control, comparison of the characteristics of the perceptually fluent speech of stutterers and nonstutterers as a method of studying stuttering…

This paper examines some of the problems that arise when conducting multivariate analyses with incomplete data. The literature on the effectiveness of several missing data procedures (MDP) is summarized. The most widely used MDPs are: (1) listwise deletion; (2) pairwise deletion; (3) variable mean; (4) correlational methods. No MDP should be used…

The overidentification of structural equation models with latent variables is discussed. The use of two- and three-indicator models is not recommended since such models do not allow a testing of the crucial assumption of unidimensionality among indicators in most cases. Models with four or more indicators may be more sensitive to departures from…

The value of variance is emphasized, and the element of design, frequently not adequately understood, is clarified to underscore the importance of variance to the researcher. Two analytic methods, analysis of variance (ANOVA) and multiple regression, are discussed in terms of how each uses/applies variance. Advantages and major difficulties with…

L. A. Marascuilo and R. C. Serlin (1988) note that stepwise regression is a method used frequently in social science research. C. Huberty (1989) characterizes such applications as being "common". In support of this latter statement, a review of dissertations by B. Thompson (1988) demonstrated that dissertation students frequently use…

Examined the accuracy and validity of self-reports and their effect on tests of attitude-behavior relationships. Self-reports were reasonably accurate, but they produced results different from actual behavior in attitude-behavior tests. Concludes that self-reports and actual behavior should be measured, tested, and modeled separately. (Author/LS)

Self-selection bias poses a major threat to the validity of research findings in naturalistic, quasi-experimental, or single-group designs. A new method of addressing self-selection bias in naturalistic evaluations of prevention programs was implemented. The study, involving voluntary exposure to multicomponent interventions, was developed and…

This article describes the Munich Longitudinal Study of Giftedness (initially including about 25,000 students) and concludes that, although the multidimensional model proved to be useful in predicting achievement behavior, the typological attempts failed. Distinct differences between academically gifted and creatively gifted students were found.…

Addresses the implicit assumption that instructional media represent meaningful experimental variables independent of instructional content or strategy. Results of computer-based instruction (CBI) studies (both well-designed and flawed) and meta-analyses are reviewed to support the authors' position that this assumption is invalid, and new…

This study found that accuracy in predicting the out-of-home placement of children with severe disabilities increased little in a large cross-sectional sample (n=5,992) over a smaller semilongitudinal sample (n=141). Factors such as age, adaptive and maladaptive behavior, and ethnicity are discussed. (Author/JDD)

The Bean and Metzner Nontraditional Undergraduate Student Attrition Model appeared to be a good model to address community college student attrition because it takes into account the environmental variables that colleges must consider to enhance persistence. A study was conducted to determine how well the Bean and Metzner Model fit with community…
