The use of a quasi-equiprobability model in the measurement of observer agreement involving dichotomous coding categories is described. A measure of agreement is presented which gives the probability of agreement under the assumption that observation pairs reflecting disagreement will be equally probable. (Author/JKS)

The study reported differences in agreement among four experienced listeners who analyzed the articulation skills of 97 four- and five-year-old children. Place and manner of articulation revealed differences of agreement, whereas voicing and syllabic function contributed little to agreement or disagreement. (Author)

Research indicates that three samples may not give a good indication of a workbook's narrative readability level. (MKM)

Investigating use of maximum v averaged scores in physical and motor multiple-trial tests as indicators of performance, this article concludes use of mean scores is still most appropriate in terms of scientific estimations of true performance given multiple fallible empirical measures. (JC)

An introduction is provided to the use of confirmatory factor analysis to test measurement invariance and stability in longitudinal research. The approach is illustrated through examples representing one or two constructs in one to three measurement waves. Basic issues in establishing measurement invariance are discussed. (SLD)

Studies of the reliability and validity of scores on the Religious Orientation Scale (G. Allport and J. Ross, 1967) were reviewed with respect to social desirability. Meta analysis shows that one scale correlates with social desirability, but another does not, suggesting that partialing out this variance is not recommended. (SLD)

Developed and validated an instrument designed to measure the perceived measurability and importance of the National Athletic Trainers' Association Athletic Training Educational Competencies. Data from 931 athletic trainers and sport medicine physicians support 6 constructs, each of which demonstrates high reliability. (SLD)

Conducted a reliability generalization study of five of the most prominent adult attachment style measures. Results from this investigation of 154 previously published stories indicate that the average score reliabilities across studied varied considerably across instruments and subscales. (SLD)

Conducted a reliability generalization study of Kolb's Learning Style Inventory (LSI; D. Kolb, 1976). Results for 34 studies indicate that internal consistency and test-retest reliabilities for LSI scores fluctuate considerably and contribute to deleterious cumulative measurement error. (SLD)

Discusses reliability issues in light of recent studies and debates focused on psychometrics versus datametrics terminology and reliabilities generalization. Discusses the way multiple perspectives on score reliability may affect research practice, editorial policies, and reliability generalization across studies. (SLD)

Provides information to help lawyers and expert witnesses understand how well-established legal principles demand the exclusion of suggestion-induced accusation in child abuse cases just as they do suggestion-induced identifications. Discusses legal arguments that support the exclusion of accusations obtained through suggestion and provides an…

Used reliability generalization to synthesize findings from 30 samples of raw data, involving 2,407 participants, about the self-reporting of emotions using the Differential Emotions Scale (C. Izard and others, 1993). Higher socioeconomic status is positively associated with increased internal consistency; gender appears unrelated to reliability…

Explains why ISDN (integrated services digital network) is the most practical solution for high-speed remote access, including reliability, cost, flexibility, scaleability, standards, and manageability. Other data transmission options are discussed, including asymmetric digital subscriber lines (ADSL), high-speed digital subscriber lines (HDSL),…

Some concerns about the use and reporting of coefficient alpha are addressed. It is also shown that alpha is not a measure of homogeneity or unidimensionality. Four ways in which researchers use of alpha can convey inaccurate information or a lack of understanding are reviewed. (SLD)

The Career Maturity Inventory-Revised (CMI-R) and Occupational Plans Questionnaire were completed by 157 high school students. Analysis of construct and criterion validity demonstrated modest but limited support for CMI-R. Its scales were found to have low internal consistency reliabilities. The Attitude Scale, Competence Test, and total score…
