Livingston's work is a careful analysis of what occurs when one pools two populations with different means, but similar variances and reliability coefficients. However, his work fails to advance reliability theory for the special case of criterion-referenced testing. See ED 042 802 for Livingston's paper. (MS)

This paper examines the individual consistency of eleventh grade respondents in normal test-retest situations as well as situations involving changed response methods. It postulates the personality-trait "discriminator" (high vs low) and confirms the trait's influence on individual consistency within and across Biology Cognitive…

Observer disagreement is important because it limits the reliabilities of observational measures. To avoid this limitation, observers should be trained, and criterion-related and intraobserver agreement measures should be used both before and during a study. Several agreement coefficients are examined for their applicability. (Author/BW)

This paper suggests that in addressing the issue of parent-professional congruence in child assessment, researchers should avoid focusing on the conventional aspects of interrater reliability and rater interchangeability, but rather should focus on the reliability of the pooled assessment information from parents and professionals. A…

Standardization data based on responses of 616 Puerto Ricans to the Spanish version of the Wechsler Adult Intelligence Scale (D. Wechlser, 1981) reveal reliability data and base rates to assist in evaluating the clinical significance of differences between Performance Intelligence Quotient (PIQ) and Verbal Intelligence Quotient (VIQ).…

Problem behavior is a primary barrier to successful community inclusion for people with developmental disabilities and therefore a major priority for intervention efforts. Recently, researchers and clinicians have begun to focus on the systematic assessment of a broad range of contextual variables that purportedly affect problem behavior. In the…

This study examined the reliability and validity of a Korean-translated version of the Gifted Rating Scales--School Form (GRS-S) and explored the effect of gender, rater, and grade. Data were collected from elementary schools in a metropolitan area and a midsize town in South Korea. In all, 49 elementary school teachers and 272 parents…

Randomization should be employed whenever possible but the use of carefully controlled nonrandomized data to estimate causal effects is a reasonable and necessary procedure in many cases. (Author/BJG)

A MEASURING OPERATION IS A SAMPLE FROM A UNIVERSE OF ADMISSIBLE OBSERVATIONS....GENERALIZABILITY STUDIES ESTIMATE THE MAGNITUDE OF THE DISCREPENCIES LIKELY TO ARISE UNDER A GIVEN MEASURING PROCEDURE, AND PROVIDE FORMULAS FOR ESTABLISHING INTERVAL AND POINT ESTIMATES OF THE UNIVERSE SCORE. A MULTIFACET GENERALIZABILITY ANALYSIS DEPARTS IN SEVERAL…

In this brief note, the author argues against the use of squared correlation coefficients as measures of explained variance. (JKS)

Multivalent relations, inferred as relationships with an added dimension of discernment, are realized as weighted graphs with multivalued edges. A unified treatment of the threshold problem is discussed and a reliability measure is produced to judge various partitions. (Author/EM)

Notes that, while researchers seek accurate causative factors for suicidal behavior, validity and reliability of certification of suicide deaths by coroners and medical examiners have been questioned. Provides overview of existing vital statistics registry system, proposes innovations that could improve quality of officially reported suicide…

An adjustment to the Rand statistic, which will allow comparison across different levels for number of clusters found within a classification, is proposed. This adjustment permits the user to compare several different classifications with respect to classification agreement, while correcting for the contribution of chance to any observed…
