Drawing on experience between 2000 and 2007 in developing a validity argument for the high-stakes Test of English as a "Foreign Language[TM]" (TOEFL[R]), this paper evaluates the differences between the argument-based approach to validity as presented by "Kane (2006)" and that described in the 1999 "AERA/APA/NCME Standards for Educational and…

The Lothian Birth Cohort 1936 sample is in a uniquely good position to provide relevant data on social class mobility patterns over most of the last century. These participants, with known ultimate social class attainment, took a validated mental test in the Scottish Mental Survey of 1947 and were followed up at approximately age 70. Then, besides…

Reliable and valid assessment of individuals who are English language learners (ELL) has presented a dilemma to psychologists, and school psychologists in particular, as it is complicated by the small number of professionals qualified to serve as bilingual examiners. Some psychologists use ancillary examiners during testing when no bilingual…

In our day-to-day striving, dissonance litters obstacles along the path of personal development and these obstacles cause pain and hinder growth. An environment that is relatively free from dissonance should foster personal development and enhance growth. The Dissonance Test-Revised (DISS-R), a test derived from second force psychology, was…

Academic psychology has long been composed of two disciplines, one experimental and one correlational. These two disciplines each developed their own method of studying structure in data: multidimensional scaling (MDS) and factor analysis. Both methods use similar kinds of input data, proximity measures on object pairs. Both represent the object…

The reliability of residual scores created in the analysis of covariance in pretest-posttest designs, adjusted for a singe covariate, is compared with that of simple difference scores as relevant parameters vary. Little gain in reliability is created by analysis of covariance, which also suffers from reliability problems. (SLD)

Recent empirical research has shown that children with sexual behavior problems and adolescents who offend sexually are diverse populations consisting of several subtypes (Hall, Mathews, & Pearce, 2002; Pithers, Gray, Busconi, & Houchens, 1998; Worling, 2001). This article reviews the descriptive and empirical research related to identifying…

To determine if a sample of children meeting diagnostic criteria for a Pervasive Developmental Disorder (PDD) display symptoms and impairment related to Attention Deficit Hyperactivity Disorder (ADHD) sufficient to warrant a comorbid diagnosis of ADHD. Further, do children with PDD displaying such symptoms demonstrate more impairment in daily life…
