Critically examining common statistical approaches and their strengths and weaknesses is an important step in advancing recreation and leisure sciences. To continue this critical examination and to inform methodological decision making, this study compared three approaches to determine how alternative approaches may result in contradictory…

Presents procedures for reducing attrition in clinical research and provides a case study for examination by researchers. Includes lists of preventative strategies and statistical methodologies to reduce attrition and bias. Argues that early planning for attrition by adjusting sample sizes is a scientifically sound approach to clinical research…

A popular abbreviated version of the Marital Conceptualization Scale (MCS) was administered along with other measures of conventionality to 181 married couples. Correlational analysis failed to confirm the construct validity of the MCS as defined by the instrument's author. The investigators proposed renaming the response set "marital social…

Contains seven articles discussing the application of meta-analysis to research on outcomes in psychotherapy. Provides a framework for understanding meta-analytic procedures and outlines major techniques. Reviews criticisms of integration of psychotherapy outcome research. Evaluates comparative therapy outcome research and discusses limitations of…

This paper reports 20 unsolved problems in educational measurement and points toward what seem to be promising avenues of solution. The first group of concerns involves validity, posing the problems of obtaining suitable validity criteria, determining and measuring the predictor variables that best characterize the traits and proficiencies of…

Research on assessing the cultural fairness of individual test items is reviewed, with emphasis on Birnbaum's three-parameter logistic model. As defined in this review, differential item characteristics are exhibited when examinees from one group have a lower probability of answering correctly than do examinees of equal ability from another group.…

The paper identifies and addresses four methodological weaknesses common to most previous studies that have used LISREL confirmatory factor analysis to test for the factorial validity and invariance of a single measuring instrument. Specifically, the paper demonstrates the steps involved in: (1) conducting sensitivity analyses to determine a…

This project was conducted to refine and expand previous research indicating the need for an instrument counselors can use in working with area secondary schools and potential students to assess their progress in making career and training decisions. Instruments developed during this research process were pilot tested at two area schools and…

The criterion-oriented problem of test bias and fairness in selection is compared to the construct-oriented problem of comparability of test scores in cross-cultural research. These problems are shown to have important similarities, and their studies may supplement each other. In a formulation of psychometric criteria for the comparability of test…
