To determine if the observed correlation between two variables can be "explained" by a third variable, a significance test on the partial correlation coefficient is often used. This can be misleading when the third variable is measured with error. This article shows how the problem can be partially overcome. (Author/BW)

Describes the development and validation of a method for pretesting the reader interest value of comic strips and cartoons so that the "best" ones may be selected for printing from the available options. (Author/GT)

When administered to 125 deaf youngsters, ages 5-12, the WISC performance test had good reliability and predictive validity, but administration to some young or physically handicapped children proved difficult. The Colored Progressive Matrices proved satisfactory with older subjects, but its suitability for younger deaf children was not confirmed.…

A model was developed for estimating individuals' true changes on test scores using the additional information provided by an auxiliary variable correlated with a trait being measured. This provides an improved and more precise estimate when compared with simple difference scores. It involves the reliability of "X" scores only. (SLD)

How the validity of gain scores varies with the standard deviations of pretest and posttest scores and the correlation between the two are analyzed. Earlier findings that under realistic testing conditions difference scores can have excellent predictive value are supported. Conditions under which gain scores have optimum validity are specified.…

Presents data from two studies determining the validity of various measures of physical activity in preschool children. One explored how certain measures of activity predicted observed behavior. The other examined the Caltrac motion sensor's predictive validity. Results indicate the Caltrac monitor is sensitive to children's individual differences…

Among the various tests employed in personnel selection, handwriting analysis, or graphology, has enjoyed long-standing international popularity despite being highly contentious. This report contains not only an evaluation of the current published scientific reviews on the use of graphology in personnel selection, but also an evaluation of several…

The present study was conducted to determine whether combining the results of multiple actuarial risk scales increases accuracy in predicting sex offender recidivism. Multiple methods of combining 4 validated actuarial risk scales--the Violence Risk Appraisal Guide, the Sex Offender Risk Appraisal Guide, the Rapid Risk Assessment for Sexual…

This study explored the use of the Formal Elements Art Therapy Scale (FEATS) with a population of persons with a DSM-IV diagnosis of Substance Use Disorder who were court ordered for treatment. Two groups of adults (N = 40) were closely matched on age, gender, race, socioeconomic status and education level, and were administered the Person Picking…

This article sets out a detailed commentary on the neglected end of the assessment centre, namely, the candidate. It highlights the variety of ways in which assessment centres do not always live up to their claims and can act against rather than in the interests of the candidate. It shares with assessment, counselling and guidance professionals an…

This article presents a case study of selection for graduate study at the Vrije Universiteit (VU) in the Netherlands. The VU developed and implemented an assessment instrument for students with a vocational Bachelor degree wishing to pursue a Master's programme at the university. This instrument is new in the egalitarian higher education culture…

A statistical model for investigating predictive validity at highly selective institutions is described. When the selection ratio is small, one must typically deal with a data set containing relatively large amounts of missing data on both criterion and predictor variables. Standard statistical approaches are based on the strong assumption that…

From 13 objective interview items, five with adequate response variability were studied to determine if they would improve the validity of a verbal ability selection test in predicting work performance of 181 psychiatric aide trainees. In a multiple regression analysis, the verbal test correlated .27 with the weighted composite rating score.…

A study conducted with kindergarten and elementary school children showed that Piagetian tasks which measured seriation, conservation, and multiple classification were equal or superior to traditional intelligence tests in predicting number language, number line comprehension, and verbal arithmetic.
