Two hundred seventy-four boys and girls, aged 7 through 15 years, participated in a test-retest reliability study of the Developmental Tests of Visual-Motor Association. Test-retest correlations for the total group and subjects comprising categories A through D were significant. (Author/SJL)

The purpose of this article is to review applications of reliability formulas and to recommend more appropriate methods of determining the reliability of affective instruments. (SK)

Formulas for the standard error of measurement of three measures of change (simple differences; residualized difference scores; and a measure introduced by Tucker, Damarin, and Messick) are derived. A practical guide for determining the relative error of the three measures is developed. (Author/JKS)

This paper examines the properties of the Item Efficiency Index proposed by Neill and Jackson (1976; EJ 137 077) for minimum redundancy item analysis. (Author/BW)

Some procedures for estimating internal consistency reliability may be superior mathematically to the more commonly used methods such as Coefficient Alpha. One problem is computational difficulty; the other is the possibility of overestimation due to capitalization on chance. (Author/CTM)

Both the binomial and beta-binomial models are applied to various problems occurring in mental test theory. The paper reviews and critiques these models. The emphasis is on the extensions of the models that have been proposed in recent years, and that might not be familiar to many educators. (Author)

The temporal stability of three levels (primary I, primary II, and elementary) of the Metropolitan Achievement Test (MAT) when administered to children with learning disabilities was investigated. It was concluded that the MAT is reliable when used with learning disabled children. (Author/SBH)

Power analysis is in essence a technique for estimating the probability of obtaining a specific minimum observed effect size. Power analysis techniques are applied to research planning problems in test reliability studies. A table for use in research planning and hypothesis testing is presented. (Author)

Evaluated the effectiveness of 13 different Minnesota Multiphasic Personality Inventory taking direction techniques. Results indicated that from 10 percent to 81 percent of the variance associated with faking can be accounted for by various detection strategies. These techniques are recommended for clinical use.

Item endorsement rates and reliability of the Smith Quick Measure of Achievement Motivation were studied. Concluded that the scale may have too little variance to discriminate college students on achievement motivation and that, for students, one item may be inappropriately keyed. (Author)

Huynh (1976) suggested a method of approximating the reliability coefficient of a mastery test. The present study examines the accuracy of Huynh's approximation and also describes a computationally simpler approximation which appears to be generally more accurate than the former. (Author/RL)

A computer program which creates and stores a cumulative item covariance matrix upon each administration of an instrument is described. Use of this program would facilitate keeping a constant log on reliability in situations in which the test is administered to different groups over a period of time. (Author/JKS)

Test-retest and interrater reliabilities were calculated for all domains of the American Association on Mental Deficiency Adaptive Behavior Scale administered to 28 mentally retarded persons (mean age 24 years). (Author/CL)

Preliminary findings from the administration of the Leader Effectiveness and Adaptability Description (LEAD) instrument provide some support for situational leadership theory--the idea that flexible and balanced use of task and relationship behaviors is beneficial for both organizational productivity and personal satisfaction. (Author/MLF)

The study was designed to determine the effects of repeated trials on the reliability of physical fitness performance scores of thirty-six 12- to 20-year-old institutionalized mentally retarded children. (Author)
