Periodic changes in occupational classifications make it difficult to obtain consistent measures of social class over time, potentially jeopardizing research on class-based trends. The severity of this problem depends, in part, on the measurement strategies used to address those changes. The authors propose that when a sample has been coded partly…

Purpose of the Study: Missing data are a common problem encountered while implementing measurement instruments. Yet the extent to which reliability, validity, average discrimination and difficulty of the test results are affected by the missing data has not been studied much. Since it is inevitable that missing data have an impact on the…

This special series focused on treatment integrity in the child mental health and education field is timely. The articles do a laudable job of reviewing (a) the current status of treatment integrity research and measurement, (b) existing conceptual models of treatment integrity, and (c) the limitations of prior research. Overall, this thoughtful…

In most selection validation research, only the upper and lower tails of the criterion distribution are used, often yielding misleading or incorrect results. Provides formulas and tables which enable the researcher to account more accurately for the distribution of criterion within the middle range of population. (Author/RW)

Tests the reliability of Rutkowski's Singing Voice Development Measure for use in general music classrooms, grades one through six. Indicates that the rating scale, although originally designed for young children, is reliable for use when children in grades one through five perform a short, major song in solo. Reports on ancillary problems. (DSK)

The authors of this article contend that the Guinan and Foulds study was inadequately designed and executed, and the results indicate little of the "usefulness" of the test, much less illuminate the important hypothesis central to the investigation. Specific suggestions for further research in marathon group evaluation are made. (Author)

Because health behavior is often concerned with dynamic constructs, a longitudinal approach to measurement is needed. The Longitudinal Guttman Simplex (LGS) is a measurement model developed especially for dynamic constructs exhibiting cumulative, unitary development measured longitudinally. Data from the Television Smoking Prevention Project, a…

Documenting treatment integrity is an important issue in research and practice in any discipline concerned with prevention and intervention. However, consensus concerning the dimensions of treatment integrity and how they should be measured has yet to emerge. Advances from three areas in which significant treatment integrity work has taken…

The concept of treatment integrity cuts across a diversity of fields involved with providing treatments or interventions to individuals. In medical treatments, the concept of "treatment compliance" or "treatment adherence" is an important and problematic issue. In the field of nutrition, the concept of "dietary adherence" is important for…

In research with children, there is a common problem which could reduce the reliability of a questionnaire for some children but not others: verbal comprehension. (Authors)

Adventure education research struggles to measure components of the field's larger, complex processes and outcomes. Because valid measures provide the foundation of quantitative research, finding, assessing, and utilizing good measures of the outcomes and processes of adventure education are necessary. Describes measurement techniques, validity,…

Discusses the role and limitations of the Brazelton Neonatal Behavioral Assessment Scale in the continuing effort to construct an adequate account of infant development. (BH)

Special problems confront the researcher measuring the attitudes of young children who cannot readily make cognitive judgments associated with conventional psychometric scales, such as Likert scales. One measurement strategy, called the method of paired comparisons, can overcome these difficulties. The method is explained in this paper. A small…
