This study was designed to develop a single-stage submaximal treadmill jogging (TMJ) test to predict VO[subscript 2]max in fit adults. Participants (N = 400; men = 250 and women = 150), ages 18 to 40 years, successfully completed a maximal graded exercise test (GXT) at 1 of 3 laboratories to determine VO[subscript 2]max. The TMJ test was completed…

This is the first study to test whether the stages of change of the transtheoretical model are qualitatively different through exploring discontinuity patterns in theory of planned behavior (TPB) variables using latent multigroup structural equation modeling (MSEM) with AMOS. Discontinuity patterns in terms of latent means and prediction patterns…

Background: Despite a large body of international literature concerning the antecedents, correlates of and treatments for test anxiety, there has been little research until recently using samples of students drawn from the UK. There is a need to establish some basic normative data for test anxiety scores in this population of students, in order to…

With increasing numbers of women joining the evening/nighttime workforce, there is a need for quality childcare during these hours. This project, conducted in Japan, sought to compare the effects of expanded childcare on the development and adaptation of 866 young children after one year. Parents completed a survey on the childrearing environment…

Past research has largely ignored the influence of material resources on teenage parents' life outcomes. A lack of resources such as housing, child care, and financial support is hypothesized to explain the negative effect of teenage parenthood on educational attainment. Regression analyses use nationally representative data from the 1988 2000…

This study examined relationships between students' perceptions of course-related interaction and their course satisfaction within the learner-centered paradigm in distance education. A Students' Perceived Interaction Survey (SPIS) instrument was developed to examine nine separate hypotheses about the nature of course-related interaction. A…

This paper presents findings of a study that used conventional modeling strategies (student- and school-level) and a new multilevel modeling strategy, Hierarchical Linear Modeling, to investigate school effects on student-achievement outcomes for data collected as part of Phase 2 of the Louisiana School Effectiveness Study. The purpose was to…

The parental satisfaction levels of a probability sample of 197 black mothers in the United States were examined. Three-fourths of the mothers described their relationships with their children as "very satisfying." Bivariate analysis showed that satisfaction did not vary significantly by marital status or family-household structure.…

A study assessed the value of obtaining newspaper readership and attitudinal characteristics from both spouses in a household, in order to examine the influence that one spouse's media behavior may have on the other. A mailed questionnaire received 142 joint spouse responses in a small midwestern city. Results indicated that knowing one spouse's…

A growing controversy surrounds the strict interpretation of statistical significance tests in social research. Statistical significance tests fail in particular to provide estimates for the stability of research results. Methods that do provide such estimates are known as invariance or cross-validation procedures. Invariance analysis is largely…

The stepwise regression method of selecting predictors for computer assisted multiple regression analysis was compared with forward, backward, and best subsets regression, using 16 data sets. The results indicated the stepwise method was preferred because of its practical nature, when the models chosen by different selection methods were similar…

The purpose of this paper is to demonstrate how multiple linear regression provides a viable statistical methodology for dealing with meta-analysis in general, and specifically with the issues of nonindependence and design complexity, such as multiple treatments. Since the F-test and t-test are special cases of the general linear model,…

A study tested a delivery skills method of instruction for reducing public speaking anxiety. Subjects were 59 male and 71 female undergraduates (ranging in age from 17-49) enrolled in a basic public speaking course at a midwestern university during the 1986-87 academic year. The Personal Report of Public Speaking Apprehension (PRPSA) which…

An evaluation of the performance of and attitudes toward the beginning course in economics at three mid-western collegiate institutions is investigated in this study. (Editor)
