The aim of this article is to describe the development and validation of the Parental Monitoring Instrument (PMI). The PMI was administered to a sample of 518 parent-adolescent (aged 12 to 17 years) dyads. Initial findings provide evidence of instrument reliability and validity. The exploratory factor analysis results suggested a seven-factor…

The authors describe the development of the Privilege and Oppression Inventory, a measure that assesses counselors' awareness of privilege and oppression along dimensions of race, sexual orientation, religion, and gender. Initial item development as well as psychometric information derived from factor analyses, reliability estimation, and…

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…

Maximally reliable composites found in canonical reliability when expressed in the form of a canonical factor analysis solution are shown to have highly desirable data reduction properties. Theoretical relationships among canonical factor analysis, principal components analysis and canonical reliability analysis are emphasized. (Author/JKS)

Too many researchers speak of "the reliability of the test," thus indicating their basic misunderstanding of reliability. This paper explains classical reliability and the score features that influence coefficient alpha. It explains when coefficient alpha can be negative, even though it is conceptually a variance-accounted-for statistic.…

Restriction of range occurs whenever design or circumstances abbreviate the values of one or both variables being correlated. Range restriction has an impact on score validity, score reliability, and statistical power. As a result, researchers need a more sophisticated concept of the relationship between variance and correlation than the simple…

Because reliability is a function of scores, and not tests per se, it is inaccurate to hold that a given test will yield scores with the same reliability across samples. Therefore, score reliability should always be reported and interpreted in both measurement and substantive studies. In an effort to facilitate this outcome, this paper is intended…

The Delphi method is a means of structuring group communication process so that a group of experts can gather information or forecast future problems effectively. A primary objective of a Delphi study is to obtain consensual and consistent opinions from a group of experts in two or more successive rounds on a given research subject. Consensus and…
