Analyzed published data on the Wechsler Adult Intelligence Scale (WAIS) to ascertain whether the Information and Vocabulary subtests can function as measures of intelligence. Concluded that the addition of more WAIS subtests will not result in any increase in predictive validity and these additional tests, therefore, lack incremental validity.…

A short form of the MMPI, the Improved Readability Form (IRF), was shown to contain items that were more readable, more stable, and less ambiguous than excluded items. Results suggest that the IRF may function as well as available short forms with persons of normal and near normal intelligence. (Author)

Evaluated discriminant validity in frequently used measures of irrational beliefs relative to measures of trait anxiety in college students (N=142). Results showed discriminant validity in the Rational Behavior Inventory but not in the Irrational Beliefs Test and correlated cognitive rather than somatic aspects of trait anxiety with both measures.…

Critiqued and reanalyzed a recent study of the validity of five Minnesota Multiphasic Personality Inventory (MMPI) alcoholism scales. The original study concluded that these scales were invalid in terms of classifying patients in regard to alcoholic status. Reanalysis provides evidence for the validity of four of the five scales.

Examines the validity of a Minnesota Multiphasic Personality Inventory code type interpretive program. Results showed the system was highly rated by three independent experienced clinicians. The program can be used in validating other automated test interpretation systems. Feedback by expert judges can be used to improve such systems. (Author/JAC)

Tested the hypothesis that subjects with elevated MMPI profiles would exhibit qualitatively different word associations from those with normal MMPI profiles. Results are interpreted as demonstrating the construct validity of the Sc scale in that the more pathological the profile, the greater degree of cognitive disturbance exhibited. (Author)

Paper presents normative data on the Mathematics Anxiety Rating Scale (MARS), which measures anxiety associated with number manipulation or mathematics concepts. (Authors)

Examined the psychometric properties of the Multidimensional Health Locus of Control (MHLC) Scales with alcoholic patients (N=100). The three MHLC Scales appear to measure largely independent dimensions of locus of control beliefs specifically related to health. Factor analyses suggest that the instrument is factorily valid. (Author/JAC)

Studied the effect of different base rates of a target phenomenon on psychometric efficiency when an explicit decision-making rule was used to evaluate police officers. Concluded that numerous predictive indices would be required to screen such a heterogeneous population. (Author/JAC)

Developed, on the basis of responses from 608 undergraduate students to the 33-item Marlowe-Crowne Social Desirability Scale, three short forms of the scale. Comparisons made between the short forms examined in this investigation suggest the 13-item form as a viable substitute for the regular 33-item Marlowe-Crowne scale. (Author)

Described the development and evaluation of a measure of cognitive belief systems and thinking styles. Reliability and validity results were poor for junior college students. For university and nonstudent populations, cognition scores discriminated social anxiety. The Cognition Scale of Assertiveness is a reliable and valid measure of cognitive…

Research on the Wechsler Memory Scale (WMS) is reviewed, including the relationship of Memory Quotient to Full Scale IQ. Despite its limitations, WMS has been a sensitive test of short-term memory, which may be helpful in identifying dominant (left) temporal lobe impairment. (Author/SJL)

Explored the hierarchical structure of mental abilities by comparing principal component analysis with a hierarchical cluster analysis algorithm on a short test battery for 182 children. Both the linear principal component analysis and the nonlinear hierarchical clustering analysis confirmed the hierarchical organization of mental abilities. (JAC)

Derived appropriate K-corrections for Minnesota Multiphasic Personality Inventory-168 factor scales and a general psychopathology screening scale (PSY). Determined percentile distributions of K-corrected scales in a normal sample (N=1438) and constructed a percentile profile sheet to facilitate clinical use (N=1048). Examined validity of the…

Examined the Tennessee Self Concept Scale for cultural and sex differences with college students (N=202). Data did not support generalizability of normed data across cultures. Analysis showed significant differences according to sex of respondent, and raised questions concerning the validity of certain clinical uses and interpretations of the…
