This study compared the relative accuracy of (a) single Occupational Scale (OS) scores on the Strong Interest Inventory (SII) and (b) multiple-predictor scoring functions for discriminating members of nine occupations from people-in-general. The functions were constructed using discriminant function analysis with 4797 adults drawn from criterion…

Four identity dimensions (Commitment Making, Identification with Commitment, Exploration in Depth, and Exploration in Breadth) were used to derive identity statuses by means of cluster analysis in a sample of late adolescents. This strategy resulted in both a qualitative refinement and a quantitative extension of Marcia's (1966) model. Five…

It has been increasingly realized that (1) multivariate methods are essential in most quantitative studies (Fish, 1988; Thompson, 1992), and (2) all conventional parametric analytic methods are correlational and invoke least squares weights (e.g., the beta weights in regression) (Knapp, 1978; Thompson, 1991). The present paper reviews one very…

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…

Commonality analysis may be used as an adjunct to general linear methods as a means of determining the degree of predictive ability shared by two or more independent variables. For each independent variable, commonality analysis indicates how much of the variance of the dependent variable is unique to the predictor and how much of the predictor's…

A sample of 132 junior high school students completed a biographical data sheet, short forms of the Beck Depression Inventory, a Sensation-Seeking Scale, the Family Environment Scale, a social support index, and a life stress inventory, to determine to what extent depression in young adolescents could be predicted. (Author/PN)

Investigated the effects of fee payment sources on the duration of psychotherapy for 160 outpatients. Univariate results indicated that scaled fee patients had significantly more sessions than those whose fee was paid by Medicaid. Multivariate results, however, indicated that education and sex accounted for most of the variance in treatment…

Investigated the effects of biomedical and social-environmental conditions on cognitive and language development in children toddlers. Hypothesized a strong effect of biomedical factors in first two years and a strong environmental influence at three years. Used analysis approach to estimate variables assumed to underlie measurement data. Results…

Three groups of fifth graders (total n=104) classified as either at-risk and with anti-social behavior/hyperactivity, at-risk only, or controls were contrasted on protective and risk factors from third-grade using multivariate analyses. Seven of eight variables were found to predict group membership including protective factors (e.g., academic and…

We investigated preferences for climate change mitigation policies and factors contributing to higher levels of policy support. The sample was comprised of 316 Michigan and Virginia residents, all of whom completed mail surveys. Of the eight policies proposed to reduce the burning of fossil fuels, respondents overwhelmingly indicated they would…

Career paths and transition services were investigated for students with disabilities who were exiting special education for comparison with two models of transition developed by Siegel (1998) and Greene (2003). Teachers and parent-mentors from 52 local education agencies (LEAs) conducted a record review and an exit interview of 741 students with…

This study examined the predictors of longevity among 40 late adolescent romantic couples (mean age males=17.71 years; mean age females=17.18 years). Subjects were given a revealed differences task where they were asked to solve their disagreements. The joint task was recorded, transcribed and analysed by two raters. At 3, 6, 9, 12, 18, and 24…

Risk perception was examined in relation to sexual victimization among 262 college women. Participants were presented with written vignettes that described hypothetical situations with a stranger and with an acquaintance. Participants' hypothetical decision to leave a potentially risky situation with an acquaintance predicted rape and…

Since canonical correlation analysis subsumes multiple regression as a special case, and since commonality analysis (a variance partitioning procedure) has proven useful in interpreting multiple regression results, the interpretation of canonical correlation results might also be enhanced by the use of commonality analysis. In this paper, a…

Advantages of the use of multivariate commonality analysis are discussed and a small data set is used to illustrate the analysis and as a model to enable readers to conduct such an analysis. A noteworthy advantage of commonality analysis is that commonality honors the relationships among variables by determining the degree to which predictors in a…
