This study adopted a person-centered approach to examine organized patterns of psychological factors and their relations to achievement and engagement in a sample of high school students. Four types of students characterized by unique configurations of cognitive, motivational, and affective characteristics were identified in both the male and…

A new approach to partialling components is used. Like conventional partialling, this approach orthogonalizes variables by partitioning the scores or observations. Unlike conventional partialling, it yields a common component and two unique components. (Author/GDC)

New tests for comparing the strength of association between a variable and each of two potential predictor variables are proposed and compared to an existing test in a simulation study. Recommendations for use are made. (Author/JKS)

Authors discovered significant correlations between couse ratings and variables representing commitment and course-end attitudes toward the course; conclusions suggested steps an instructor might take to improve his ratings.'' (Authors)

Assessed the relative predictive validity of obvious (O), neutral (N), and subtle (S) items of the MMPI MA scale for 86 males. Subtle-obvious ratings were compared to criteria in questionnaire, life-history, and objective tests. Correlations among the criteria were generally insignificant, suggesting that hypomania is not a homogeneous construct.…

To be able to conclude anything firm about either a predictor or a criterion from the correlation between the two, a whole range of conditions must be met. Those conditions, which are in effect predictors of validity, are discussed, with the emphasis on the educational situation. (Author)

Compares four closed-formula estimators (Burkett, Claudy, Rozeboom, Browne) and the omit-one method for estimating TRS, the true shrunken correlation (not to be confused with TR, the true multiple correlation). Recommendations are based on artificial populations with known TRS. (Author/SV)

Presented at the national conference for AERA (American Educational Research Association) . This study examined whether there are distinct differences in the demographic characteristics, HSGPA, first-year college performance, and second-year college retention rates among students who have discrepant CR-W performance.

The goals of our study were to determine the predictive value and usability of an audience response system (ARS) as a knowledge assessment tool in an undergraduate medical curriculum. Over a three year period (2006-2008), data were collected from first year didactic blocks in Genetics/Histology and Anatomy/Radiology (n = 42-50 per class). During…

The effectiveness of the Self-Appraisal Questionnaire (SAQ) in providing estimates for predicting violent and nonviolent recidivism over a 9-year period is examined. The SAQ is a quantitative risk/need instrument consisting of 72 items that compose eight subscales. There were 657 federally sentenced Canadian male offenders who completed the SAQ…

To test the predictive efficiency of the Holland Occupational Classification and the related hypotheses concerned with occupational achievement and stability of career from Holland's theory of careers, the classification was applied to a national sample of 973 male retrospective work histories. Analyses were performed by organizing and…

To examine the implications of differences in reflection-impulsivity for later academic achievement, 70 children were administered the Matching Familiar Figures test (MFF) in grade 4 and the Comprehensive Tests of Basic Skills (CTBS) in grades 4, 5, and 6. (Author/JMB)

Tested the utility of an exchange model for predicting divorce or withdrawal of divorce petitions, using court records and interviews of men and women who were divorced or subsequently withdrew their divorce petitions. Discriminant function analyses indicated that an exchange model can predict divorce versus petition withdrawal. (JAC)
