The procedures yielding confidence intervals for maximized alpha coefficients of Joe and Woodward are reviewed. Confidence interval procedures of Whalen and Masson are next reviewed. Results are then presented of a Monte Carlo investigation of the procedures. (Author/CTM)

Finds that the test/retest reliability coefficients for the "Collett-Lester Fear of Death Scale" and the "Lester Attitude toward Death Scale" were significant, but only low to moderate in significance. (RL)

Proposes formulas for expected true-score measures and reliability of binary items as a function of their Rasch difficulty when the trait (ability) distribution is normal or logistic. Provides an illustrative example for using the proposed formulas. (SLD)

Conducted a reliability generalization study of the Marlowe-Crowne Social Desirability Scale (D. Crowne and D. Marlowe, 1960). Analysis of 93 studies show that the predicted score reliability for male adolescents was 0.53, and reliability for men's responses was lower than for women's. Discusses the need for further analysis of the scale. (SLD)

Explored variability in reliability scores on a career scale, the Career Decision-Making Self-Efficacy Scale (K. Taylor and N. Betz, 1983). Of the 49 studies examined, 41% reported score reliabilities. Of the five subscales, Problem Solving shows the lowest score reliability. Higher score reliability is associated with age, racial/ethnic…

Examined the score reliability of a measure of life satisfaction, the Life Satisfaction Index (LSI) using 34 research studies. Results reveal an average reliability of 0.79. Results provide evidence for adequate reliability of LSI scores across a variety of sample characteristics, but they must be interpreted with caution given the small sample…

Methods are offered for conducting hypothesis testing associated with disattenuated validity coefficients to overcome limitations of some other suggested approaches. Through using classical test theory's notion of reliability in the form of structured path models, such hypothesis testing may be done with hierarchically related structural equation…

Dynamic generalizations of reliability and validity that will incorporate longitudinal or developmental models, using latent curve analysis, are discussed. A latent curve model formulated to depict change is incorporated into the classical definitions of reliability and validity. The approach is illustrated with sociological and psychological…

The clarification provided by Williams and Zimmerman on the reliability of gain scores is translated into recognizable patterns of change that tend to produce reliable or unreliable gain scores. The relevance of the traditional idea of reliability to the measurement of change is also discussed. (SLD)

Designed an instrument to measure adolescents' attitudes toward school and teachers, goal-valuation, motivation, and general academic self-perceptions. Tested the developed survey with samples of 146, 200, and 299 high school students. Findings suggest the scale has adequate construct validity, criterion-related validity, and internal consistency…

Examined the asymptotic distributions of three reliability coefficient estimates: (1) sample coefficient alpha; (2) reliability estimate of a composite score following factor analysis; and (3) maximal reliability of a linear combination of item scores after factor analysis. Findings show that normal theory based asymptotic distributions for these…

Discusses the money wasted on ineffective training programs and the resulting surge in interest among training professionals in conducting learning evaluation and return on investment (ROI) measurement. Describes Kirkpatrick's four-level evaluation concept; questions regarding measurement validity and reliability; and new developments in learning…

Considers the degree of bias in testlet-based alpha (internal consistency reliability) through hypothetical examples and real test data from four tests of the Iowa Tests of Basic Skills. Presents a simple formula for computing a testlet-based congeneric coefficient. (SLD)

Discusses the advantages of metal building and roofing systems, especially the use of steel. Considers such factors as installation ease and design flexibility, reliability and durability, and cost-effectiveness. (PKP)

A measure, the Self-Injury Trauma Scale, is described for classifying and quantifying surface tissue damage. The scale permits differentiation of self-injurious behavior according to topography, location of the injury on the body, type of injury, number of injuries, and estimate of severity. High interrater reliability has been found. (Author/DB)
