INFLUENCE OF ASSESSMENT CENTER METHODS ON ASSESSORS'RATINGS

Recently a number of authors have argued persuasively that performance ratings are influenced to a large extent by the way the rater selects, organizes, stores, and recalls information. Although the influence of the rater's cognitive processes on the obtained ratings has been considered in the job-performance evaluation literature, this issue has not been considered in the assessment center literature. The purpose of the present study was to examine how assessment center methods affect the way assessors organize and process assessment center information and affect the ratings they make. Independent groups of assessors underwent one of two methods for evaluating candidates in an assessment center. Data indicated differences in the convergent and discriminant validities and differences in the factor structures of the ratings for the two methods. The pattern of results suggested that the two methods for evaluating assessment center candidates affected the way the assessors organized the assessment center information and affected the obtained ratings. Future research should consider assessment center methods and assessors as sources of variation in assessment center ratings.

Dialectical Metatheory in Family Therapy

This paper addresses the controversy in family therapy over basic philosophical issues in terms of a historical opposition between demonstrative and dialectical metatheories. It argues that advances in family therapy are indicative of the growing prominence of dialectical forms of understanding in the social sciences. Several family therapy concepts are explored as representative of the dialectical categories of motion, form, relationship, and transformation.     

Understanding and Counseling Narcissistic Clients

This article is intended to provide counselors with an overview of narcissism and its treatment. In the first section, dysfunctional narcissism is described, drawing on the diagnostic indicators presented in the DSM-III and the contemporary object relations theories of Heinz Kohut and Otto Kernberg. The second section focuses on counseling narcissistic clients.     

Primary Prevention and High Risk Populations

A primary prevention program designed to promote the personal development of individuals in a particular high risk population is discussed.     

METAANALYSES OF VALIDITY STUDIES PUBLISHED BETWEEN 1964 AND 1982 AND THE INVESTIGATION OF STUDY CHARACTERISTICS

Review and metaanalyses of published validation studies for the years 1964-1982 of Journal of Applied Psychology and Personnel Psychology were undertaken to examine the effect of (1) research design; (2) criterion used; (3) type of selection instrument used; (4) occupational group studies; and (5) predictor-criterion combination on the level of observed validity coefficients. Results indicate that concurrent validation designs produce validity coefficients roughly equivalent to those obtained in predictive validation designs and that both of these designs produce higher validity coefficients than does a predictive design which includes use of the selection instrument. Of the criteria examined, performance rating criteria generally produced lower validity coefficients than did the use of other more "objective" criteria. In comparing the validities of various types of predictors, it was found cognitive ability tests were not superior to other predictors such as assessment centers, work samples, and supervisory/peer evaluations as has been found in previous metaanalytic work. Personality measures were clearly less valid. Compared to previous validity generalization work, much unexplained variance in validity coefficients remained after corrections for differences in sample size. Finally, the studies reviewed were deficient for our purposes with respect to the data reported. Selection ratios, standard deviations, reliabilities, predictor and criterion intercorrelations were rarely and inconsistently reported. There are also many predictor-criterion relationships for which very few validation efforts have been undertaken.     

HONESTY TESTING FOR PERSONNEL SELECTION: A REVIEW AND CRITIQUE

Paper and pencil predictors of employee theft are described and studies of validity, reliability, and adverse impact of these tests are examined. Validity studies for 10 tests were grouped into 5 categories: comparisons with polygraph examination results, correlations with admissions of past theft, predictive studies using future job behaviors as criteria, comparisons of shrinkage rates before and after the introduction of a testing program, and comparisons of test scores of groups known to be dishonest with groups representing the general population. While positive correlations were consistently found, a variety of methodological differences between studies were identified which make the direct comparison of test validities suspect. High reliabilities are consistently reported, and test score comparisons by race and sex generally report no differences. Ethical issues in honesty test usage are considered and future research needs are identified.
