Paul Newton (2010), with his characteristic concern about theory, has set out two different ways of thinking about the basis upon which equivalences of one sort or another are established between test score scales. His reason for doing this is a desire to establish "the defensibility of linkages lower on the continuum than concordance."…

This article presents the author's rejoinder to thinking about linking from issue 8(1). Particularly within the more embracing linking frameworks, e.g., Holland & Dorans (2006) and Holland (2007), there appears to be a major disjunction between (1) classification discourse: the supposed basis for classification, that is, the underlying theory…

"Linking" is a term given to a general class of procedures by which one represents scores X on one test or measure in terms of scores Y on another test or measure. A recent taxonomy by Holland and Dorans (2006; Holland, 2007) organizes the various types of links into three broad categories: prediction, scale aligning, and equating. In…

Newton's article (2010) makes three main contributions to the literature. First, it is transatlantic, bringing together literatures that have been dealing with similar problems, using sometimes different methods and certainly with distinctive educational, cultural perspectives. He points out that neither of these literatures has all of the…

The article "Thinking About Linking" by Newton (2010) presents a novel philosophical perspective on the way that educational assessments should be linked. Newton starts by describing the linking framework as it was characterized in various publications and identifies a cross-cultural dimension in the definitions and uses of test…

Contends that one basic limitation of measurement techniques is that tests cannot measure unique characteristics, but only traits common to many people. Discusses limitations regarding intelligence, interest, and personality tests and concludes that test scores give us clues to be followed rather than definite measurements. (LLL)

The application of psychological testing is largely an attempt to derive probabilistic statements regarding the likelihood of occurrence of client states, choice outcomes, situational antecedents, and behavioral outcomes. Counseling psychologists share with others the occupational requirement of having to deal with uncertainty in test results and…

In general, this study found that the validity of single MMPI scales for predicting psychiatric symptoms was too low to be clinically useful for predictions about the individual case. The psychotic scales were particularly lacking in validity. The validity data for all scales is given. (Author/CG)

Interpretation of emergent variables on the basis of structure coefficients (zero order correlations between original and emergent variables) is potentially very misleading and should be avoided in favor of interpretation on the basis of scoring coefficients. This is most apparent in multiple regression analysis and its special case, two-group…

Validity coefficients, standard errors of estimate, and prediction are discussed. An argument is made for the potential utility of tests with validity coefficients of .60, .50, .40, and even .30, because they can predict the extremes, which is especially valuable for many purposes, such as counseling, college admissions, and personnel selection.…

It is recognized that parametric methods (e.g., t-tests, discriminant analysis, and methods based on analysis of variance) are special cases of canonical correlation analysis. In canonical correlation it has been argued that structure coefficients must be computed to correctly interpret results. It follows that structure coefficients may be useful…

The concept of selection ratios was illustrated for large clinical settings. Four Draw-A-Person (DAP) variables were used to predict intelligence in a sample of 601 institutionalized addicts. Results indicate that a test with low predictability across the entire distribution can often be used quite effectively for identifying poor or excellent…

In response to Ebel's article (TM 508 146) the author points out that, in emphasizing what a test is intended to measure, the vital question of what should be measured is set aside. While explicit specifications for a test should be encouraged, questions of worth ought to be prominent in designing and selecting tests. (Author/LC)

States that the correlation between social desirability (SD) and hopelessness is open to several interpretations, but, in the absence of further data, concern for false-negative rates dictates caution in interpreting hopelessness scores when assessing suicidal behavior. Presents data on the relationship of SD, hopelessness, and prediction of…
