Unlike a substantial part of reliability literature in the past, this article is concerned with weighted combinations of a given set of congeneric measures with uncorrelated errors. The relationship between maximal coefficient alpha and maximal reliability for such composites is initially dealt with, and it is shown that the former is a lower…

Data Envelopment Analysis has become a popular tool for evaluating the efficiency of decision making units. The nonparametric approach has been widely applied to educational production. The approach is, however, deterministic and leads to biased estimates of performance in the presence of measurement error. Numerous simulation studies confirm the…

The 160-item short form of the Personality Assessment Inventory (PAI) was developed for situations in which respondents complete only the 1st half of the test. The present study evaluates the adequacy and comparability of the full and short forms of the PAI in terms of a wide range of psychometric characteristics. In all, 421 participants…

A reliability generalization study was completed on the Patterns of Adaptive Learning Survey achievement goal orientation scales to assess the prediction of (a) the different orientation scales, (b) the adaptation of items to meet research needs, (c) the number of respondents completing the instrument, and (d) the publication date cited for the…

This article introduces a procedure for estimating reliability in which equivalent halves of a given test are systematically created and then administered a few days apart so that transient error can be included in the error calculus. The procedure not only estimates complete reliability (taking into account both specific-factor error and…

The ISI Impact Factor for "JOBM" is 1.793, placing it third in the JCR rankings for journals in applied psychology with a sharply accelerating linear trend over the past 5 years. This article reviews the Impact Factor and raises questions regarding its reliability and validity and then considers a citation analysis of "JOBM" in light of the…

A multi-informant study investigated the association between deception capacities and subtypes of aggression in a young early childhood sample (M=44.65 months of age, SD=13.39, N=64). A newly developed teacher report of deception had appropriate psychometric properties (reliability, concurrent validity, and construct validity). Recently introduced…

This study explores Carl Glickman's widely used Supervisory Belief Inventory (SBI). The inventory is presented in his text Supervision of Instruction: A Developmental Approach. The text suggests that the inventory is able to discern with some accuracy a teacher's or administrator's preference for one of three supervisory approaches--directive,…

This note describes a procedure for estimating the range restriction component used in correcting correlations for unreliability and range restriction when an estimate of the reliability of a predictor is not readily available for the unrestricted sample. This procedure is illustrated with a few examples. (Contains 1 table.)

Utilization of objective structured clinical examinations (OSCEs) for final assessment of medical students in Internal Medicine requires a representative sample of OSCE stations. The reliability and generalizability of OSCE scores provides validity evidence for OSCE scores and supports its contribution to the final clinical grade of medical…

The Parent And School Survey (PASS) is an instrument designed to quickly, easily, and accurately measure parental involvement in their children's education. It is based on Epstein's six-construct framework, with four items devoted to each construct. A test-retest reliability study of the PASS was conducted with 40 subjects to refine the 24 items…

The Future Events Scale (FES; S. M. Andersen, 1990) is an expectancy-based measure of optimism and pessimism, grounded in cognitive theories of depression, with implications for clinical practice. Although ample research has documented the utility of the FES in predicting important cognitive and behavioral outcomes, psychometric data on the scale…

Psychometric properties of the Inventory of Drug Use Consequences (InDUC; W. M. Miller, J. S. Tonigan, & R. Longabaugh, 1995), a self-report assessment of negative consequences associated with alcohol and other drug use, were investigated. The InDUC demonstrated sound psychometric characteristics and can be a valuable clinical tool for chemical…

Historically, states in the northeast region have differed considerably from neighboring states in the percentage of their special education student population served in different educational environments. Placement data indicate the degree to which students with disabilities are placed in the least restrictive environment (LRE) along the…

An equating study was carried out in autumn 2006 by the National Foundation for Educational Research (NFER) on behalf of Renaissance Learning, to provide validation evidence for the use of the Renaissance Star Reading and Star Mathematics tests in English schools. The study investigated the correlation between the Star tests and established tests.…
