Proactive preliminary minimum sample size determination can be useful for the early planning stages of a latent variable modeling study to set a realistic scope, long before the model and population are finalized. This study examined existing methods and proposed a new method for proactive preliminary minimum sample size determination.

The authors empirically examined whether the validity of a residualized dependent variable after covariance adjustment is comparable to that of the original variable of interest. When variance of a dependent variable is removed as a result of one or more covariates, the residual variance may not reflect the same meaning. Using the pretest-posttest…

Researchers are gaining an interest in the concept of wisdom, a more holistic yet often ineffable educational outcome. Models of wisdom abound, but few have rigorously tested measures. This study looks at Brown's (2004a, 2004b) Model of Wisdom Development and its associated measure, the Wisdom Development Scale (WDS; Brown & Greene, 2006). The…

Presents the role of human resource development practitioners as organizational researchers. Describes a model for validating instruments, constructs, and strategies, based on communication theory. Cites common errors and issues in the validation of measurement and demonstrates uses of the heuristic validation model. (SK)

Factor analysis has historically been used for myriad purposes in the social and behavioral sciences, but an especially important application of this technique has been to evaluate construct validity. Since in the present milieu both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are readily available to the researcher,…

The role of assessment is central to the current work in the field of self-regulation research, to the conceptualizations derived from empirical work, and to the operationalisation of its concepts in individual and classroom implementations. The various instantiations of the concept of self-regulation, all presuppose a detailed accounting of many…

Several techniques for conducting studies of measurement integrity are explained and illustrated using a heuristic data set from a study of teachers' participation in decision making (D. L. Taylor, 1991). The sample consisted of 637 teachers. It is emphasized that validity and reliability are characteristics of data, and do not inure to tests as…

In a previous study, a conceptual model of wisdom was created (Brown, 2004a) to better understand integrated learning outcomes. The purpose of this study is to develop a scale to measure this wisdom construct. This article discusses salient aspects of the extant professional literature regarding the measurement of wisdom and details the efforts to…
