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…

Context: Instrument validation is an important facet of survey research methods and athletic trainers must be aware of the important underlying principles. Objective: To discuss the process of survey development and validation, specifically the process of construct validation. Background: Athletic training researchers frequently employ the use of…

Two forms of Holland's Hexagon Model (circular order and circumplex structure) are proposed and evaluated to demonstrate a randomization test of hypothesized order relations and confirmatory factor analysis. The models and methods are illustrated with correlation matrices based on the Unisex Edition of the ACT Interest Inventory. (Author/SK)

The present research was stimulated by three related problems frequently faced in validation research: viable procedures for combining similar jobs in order to assess the validity of various predictors, for assessing groups of jobs represented in previous validity studies, and for assessing the applicability of validity findings between units.…

Common factor scores were compared to unfactored data-level variables as predictors in terms of the correlation of a criterion with the predicted value in multiple regression equations applied to replication (cross-validation) samples. (Editor)

This research attempts to determine whether Behavioral Observation Scales (BOS) could be improved by developing them through quantitative methods. The underlying assumption was that developing composite scales with greater internal consistency might improve their generalizability as evidenced by the cross-validation coefficients of scales based on…

This document is an English-language abstract (approximately 1,500 words) of part of a comprehensive research project concerning the Finnish matriculation examination. The goal of the project was to explore the matriculation examination as a series of tests indicative of ability differences between individuals, regardless of their causes. The…

The impact of open education on today's curriculum has been extensive. Of the many requests for research in this area, none is more important than instrument validation. This study examines the internal structure of Barth's Assumptions about Learning and Knowledge scale and explores its relationship to established "progressivism" and…

Statistical methods employed to test individual differences in dual-task performance and the existence of a general time-sharing ability are reviewed and critiqued. Specifically, both the types of data being collected and the types of data analysis procedures have been inadequate to the critical evaluation of a hypothetical…

Discusses the structure, reliability, stability, validity and usefulness of the Brazelton Neonatal Behavioral Assessment Scale (NBAS) and the results of factor and regression analyses of data collected using the NBAS. (Author/BH)
