In 2002, an article entitled "Four assumptions of multiple regression that researchers should always test" by Osborne and Waters was published in "PARE." This article has gone on to be viewed more than 275,000 times (as of August 2013), and it is one of the first results displayed in a Google search for "regression…

In the current investigation, the authors examined the diagnostic construct validity of the "Minnesota Multiphasic Personality Inventory-2-Restructured Form" (MMPI-2-RF) in a patient sample. All participants were diagnosed via the "Structured Clinical Interview" for DSM-IV Axis I Disorders (SCID-I/P). The data set used in this…

This chapter introduces theory that undergirds the role of testing adaptations in assessment, provides examples of item modifications and testing accommodations, reviews research relevant to each, and introduces a new paradigm that incorporates opportunity to learn (OTL), academic enablers, testing adaptations, and inferences that can be made from…

Using 65 items from a mental health screening questionnaire, the History Opinion Inventory-Revised (HOI-R), the present study compared three strategies of scale construction--(1) internal (based on factor analysis), (2) external (based on empirical performance) and (3) intuitive (based on clinicians' opinion)--to predict whether 203,595 U.S. Air…

The Communities That Care Youth Survey measures risk and protective factors shown in prior studies to predict adolescent problem behaviors such as drug use, delinquency, and violence. This paper describes the development and validation of cut points for the risk and protective factor scales in the Communities That Care Youth Survey that…

To continue research assessing the validity of the Balloon Analog Risk Task (BART) as a measure of risk taking, the BART was administered to a nonforensic sample of individuals with varying levels of psychopathic characteristics. Construct validity of the BART was evaluated by measuring risk-taking behavior in relation to self-reported…

Despite questions about their reliability and validity, student evaluations of teaching (SETs) are a primary measure of instructor performance. The current study examines SETs, including a thorough list of potentially relevant variables. The findings suggest that how much students perceive they learned in a course is an important predictor of SET…

This study investigated the differential validity of the Wide Range Intelligence Test, which is a new, brief measure of ability. Participants (N = 744) ranged in age from 5 through 85 years (M = 26.7 years, SD = 21.4 years) and varied by the demographic variables of gender, race/ethnicity (Anglo, African American, Hispanic), and education level…

This research report is a review and analysis of all of the published studies during the past 25+ years (since 1974) in the area of differential validity/prediction and college admission testing. More specifically, this report includes 49 separate studies of differences in validity and/or prediction for different racial/ethnic groups and/or for…
