In this study of the discriminant, convergent, and incremental validity of the Almost Perfect Scale-Revised (APS-R), university students completed the APS-R, additional measures of perfectionism, the NEO Five-Factor Inventory-Form S, and measures of self-esteem and depression. The results revealed expected significant, but not completely…

This guide provides research workers with a means of identifying certain self-report temperament factors in factor analytic studies. It is intended to promote interpretation and comparison of one factor study with another. The body of the guide is organized in 28 sections, one for each factor, followed by the reference section and an appendix…

It is proposed that common variance among Factor V personality traits might best be modeled in terms of three broad and distinct subdomains one level below the superordinate level of the so-called Big Five. Three studies are reported that point toward this compromise conception of the top of Factor V as Absorption (A), Intellectance (I), and…

Factor analytic literature published since 1965 examining the dimensionality of the adaptive behavior (AB) construct is reviewed, in light of AB's inclusion in the definition of mental retardation. Personal independence and five secondary factors were identified. AB's dimensionality varied as a function of number of methodologies and scale…

The current stage in an on-going research program of student learning is summarized. With two more years to run, provisional research provides the beginnings of a model of student learning which is neither static nor mechanistic. Recent research has placed emphasis on describing how students learn and how learning is affected by the academic…
