In this article, I provide answers to the questions posed by Will Shadish about the history and development of the Schmidt-Hunter methods of meta-analysis. In the 1970s, I headed a research program on personnel selection at the US Office of Personnel Management (OPM). After our research showed that validity studies have low statistical power, OPM…

Critically examining common statistical approaches and their strengths and weaknesses is an important step in advancing recreation and leisure sciences. To continue this critical examination and to inform methodological decision making, this study compared three approaches to determine how alternative approaches may result in contradictory…

The authors articulate objections to the organization of the recent special issue on student engagement and respond in detail to three criticisms leveled in that issue. Situating their response relative to longstanding calls to make research more relevant to practice, they argue that the validity critique inappropriately focuses on criterion…

This study assessed the validity of the Pain Apperception Test (PAT) against an accepted and validated predictive measure of pain tolerance, a Kinesthetic After Effects Task (KAE). As well, it replicated an earlier finding by Petrovich that suggested that scores derived from the PAT are related significantly to neuroticism. (Author/RK)

Attempts to establish further the validity of the Child Scale, to investigate the individual nature of the items that compose the scale and their value as demographic factors in the prediction of therapeutic outcome, and to document further the use of target complaints as criteria in investigating the outcome of psychotherapy.

A study by Malcolm R. Parks reported in "Communication Monographs" called into question the cross-situational validity of the Personal Report of Communication Apprehension (PRCA). Park's study, however, is flawed in many ways. He does not provide an adequate definition of "situation." Both the type of factor analysis he chose…

One hundred culturally disadvantaged children were tested on culture-fair (Raven) and culturally biased (WISC) tests, and scores were correlated with academic achievement. (Author)

This is part three of a three-part series concerned with the empirical development of homogeneous families of insurance company jobs based on data from the Position Analysis Questionnaire (PAQ). This part involves validity generalizations within the job families which resulted from the previous research. (Editor/RK)

Concurrent and predictive test validity data and test-retest reliability data were obtained for a work sample performance measure and two paper and pencil tests in a laboratory setting. Findings are interpreted in light of a behavioral consistency model and the practical utility of work samples as a personnel selection technique. (Editor)

Consistent with C. J. Gelso's (1979, 1993, 1997) research training environment theory, the authors hypothesized that research training environments exist in predoctoral internships. The Internship Research Training Environment Scale (IRTES) was developed to assess research training environments found in predoctoral psychology internships.…

Drawing from work on the meta-analysis of over 500 validation studies of the General Aptitude Test Battery (GATB) by the U.S. Employment Service, the paper presents a methodological message and a substantive message. Gene Glass's methods, as used by Edwin Ghiselli in personnel selection, ignore study artifacts (sampling error, error of…

The use of ability testing for job selection has become widespread in the Federal Government and in the U.S. Employment Service, which assists private sector employers. The justification for the practice is based largely on research findings claiming a high level of validity for such tests in predicting job performance. More recently, such claims…

A study was undertaken to identify the factor structure of a battery of readiness measures and to demonstrate the concurrent and predictive validity of one instrument in that battery--the Pre-Reading Screening Procedures (PSP). Concurrent validity was determined by examining the correlation of the PSP with the Metropolitan Readiness Test (MRT),…

Statistical validation is reported for the Child Care Perceiver Interview instrument, used in employing residential child care workers. Results indicate that the interview is effective in predicting job performance in group care settings and is acceptable in meeting Equal Employment Opportunity requirements. (Author/BB)
