The Personality Assessment Inventory's (PAI's) ability to predict psychopathic personality features, as assessed by the Psychopathy Checklist-Revised (PCL-R), was examined. To investigate whether the PAI Antisocial Features (ANT) Scale and subscales possessed incremental validity beyond other theoretically relevant PAI scales, optimized regression…

Background: The purpose of this study was to investigate the demographic, social and psychological factors associated with moderate-to-vigorous physical activity (MVPA) among a sample of secondary school students (N = 402). Methods: Students completed a questionnaire which examined their level of participation in MVPA and sedentary behaviours…

A theoretical model of academic motivation consisting of (a) academic self-efficacy, (b) purposefulness and intentionality, and (c) support through school counseling for autonomous learning was explored with 346 high school juniors. Regression analysis indicated academic self-efficacy and utilization of school counseling to be significant…

Five statistical techniques were used to analyze the data collected in a previous article (TM 511 223) on student achievement, attention, and motivation in secondary school mathematics and science: ordinary least squares regression, canonical correlation, factorial modeling, partial least squares path analysis, and linear structural relations…

This paper discusses Bayesian m-group regression where the groups are arranged in a two-way layout into m rows and n columns, there still being a regression of y on the x's within each group. The mathematical model is then provided as applied to the case where the rows correspond to high schools and the columns to colleges: the predictor variables…

This study was intended to serve as an example of cross-validating results from student persistence prediction models that employed commonly available pre-college student characteristics. The study investigated whether the accuracy of predicting student persistence would vary because of the use of present-year vs. previous-year parameters on…

This Monte Carlo study explored relationships among standard and unstandardized regression coefficients, structural coefficients, multiple R_ squared, and significance level of predictors for a variety of linear regression scenarios. Ten regression models with three predictors were included, and four conditions were varied that were expected to…

This manuscript summarizes an institutional research study carried out at Bowling Green State University (BGSU) concerning factors affecting time to bachelor's degree attainment. Tuition sensitivity and concern about efficient use of institutional resources point to the need for decreasing students' time-to-degree. This study enlarges upon an…

The purpose of this study was to compare five predictor models, including two least-square procedures, two probability weighting (semi-Bayesian) methods, and a Bayesian model developed by Lindley. (See also TM 501 088, TM 501 089, and TM 501 090) (Author/NE)

Discusses enrollment projection in terms of the general logic of statistical prediction. (Author)

Tested the utility of the Personal Orientation Inventory (POI), the Myers-Briggs Type Indicator, and the Girona Affect Scale in predicting the outcomes of a marathon Gestalt therapy workshop. Signigicant predictive equations were generated that use the POI to predict gains on the Girona Affect Scale. (Author/RC)

Describes a study that identified attributes that can characterize the Net generation and examines how these attributes, together with perceived seductive properties of the Internet (e.g., pleasure of control and fluidity of identity) and gratifications obtained from the Internet can predict popular Internet activities. Reports results of a…

Basic rules are suggested to replace the signed coefficient rule to infer the form of moderator effects in terms of slopes of regression lines. Steps are provided to interpret the form of moderator effects that can be achieved using only the regression coefficients of the predictor variable and interaction term. (SLD)

Studies 248 adolescents who had been in a Serious Offender Program to examine the relative predictiveness of: a common risk assessment tool; a battery of psychological tests; and a combination of demographic and theoretical factors. Regression procedures indicate that the following are significant predictors: prior commitment; male; gang members;…

This is the fourth in a series of studies whose purpose has been to develop a theoretical model of selected extramusical variables' ability to explain solo and small-ensemble festival ratings. Authors of the second and third of these (Bergee & McWhirter, 2005; Bergee & Westfall, 2005) used logistic regression as the basis for their…
