Evaluated the psychometric properties of a perceptual measure of the extent to which manufacturing organizations develop proprietary equipment, the Proprietary Equipment Scale (developed by the World Class Manufacturing study). Analysis of data from 164 manufacturing plants in 5 countries indicates that although method effects are present, the…

Describes the use of triangulation in research, a process that uses multiple measures or methods to examine a research question where a single data set would not be appropriate. Topics discussed include reliability; validity; concurrent validity; convergence; and problems in using analysis of variance as the only method to obtain data. (13…

This study of 40 hearing-impaired college students found that highly intelligible speakers were uniformly consistent in their speech production patterns, whereas speakers who exhibited low overall speech intelligibility were either extremely consistent in their aberrant production patterns or extremely inconsistent in their error patterns.…

The distribution of databases physically separates users from those who administer the database and the administrators who perform database administration. By drawing on the work of social scientists in reliability and validity, a set of concepts and a list of questions to ensure data quality were developed. (Author/MLW)

Uses three hermeneutical or quasi-hermeneutical studies in career development to illustrate important dimensions of this type of research. Discusses collecting, recording, and analyzing research material and presenting the interpretative framework. Addresses issues of subjectivity, reliability, validity, accessibility, feasibility, and…

Uses hierarchical cluster analysis to develop a typology of verbal aggression as experienced by undergraduate students. Reveals three broad domains of attack: group membership, personal failings, and relational failings. Demonstrates reliability, predictive validity, and content validity for the typology. Reveals that aggressive messages can be…

A conceptual model of quality of life, developed at the Centre for Health Promotion at the University of Toronto (Canada), and associated instrumentation for collecting data from persons with developmental disabilities are presented. Results from a preliminary study with 41 participants support the reliability and validity of the model's…

Describes a study at the University of Leiden (Netherlands) that investigated whether students with different learning styles used different study strategies in a hypertext reading environment, the role of strategy regulation in strategy use, the consistency of strategy use over two different reading tasks, and use of the Inventory of Learning…

Examined reliability and validity of binge eating disorder (BED), proposed for inclusion in Diagnostic and Statistical Manual of Mental Disorders (DSM), fourth edition. Interrater reliability of BED diagnosis compared favorably with that of most diagnoses in DSM revised third edition. Study comparing obese individuals with and without BED and…

The reliability of the growth rate parameter estimate of Willet for a linear growth model is derived and examined critically. The effects on the reliability of the growth rate of intervals between longitudinal measurements and the covariances between longitudinal measurements are distinguished. (SLD)

Three types of methodological issues particularly salient in research involving the assessment of substance use or abuse are discussed with strategies for avoiding problems: (1) the reliability and validity of methods; (2) the variability and episodic course of substance use; and (3) the heterogeneity of individuals with substance use disorders.…

Psychophysiological measures are generally those in which electrodes measure central or autonomous nervous system or skeletomotor activity with the goals of establishing linkages between the measurement and specific psychological processes. Psychophysiological methods and the difficulties inherent in their use are discussed. Guidelines are…

Discussion of the Internet highlights its use in libraries and the need to teach patrons what it can and cannot be used for. Topics include the number and variety of existing sources, vendor organization and reliability issues, speed, quality control and regulation issues, and permanence of sources. (LRW)

Discussion of document delivery focuses on fee-based information services. Fee-based information services are defined; reasons for using such services are considered, including reliability, responsiveness, and individualized attention; future directions are discussed; and networking possibilities are explored. (LRW)

Describes a study in which several different sets of hypertext links are inserted by different people in full-text documents. The degree of similarity between the sets is measured using coefficients and topological indices. As in comparable studies of inter-indexer consistency, the sets of links used by different people showed little similarity.…
