Cognitive interviewing (CI) is a method to identify sources of confusion in assessment items and to assess validity evidence on the basis of content and response processes. We introduce readers to CI and describe a process for conducting such interviews and analyzing the results. Recommendations for best practice are provided.

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.

Compares approaches to modeling ordinal outcome variables, including assumptions, interpretations, and limitations. Explores how the multiple regression approach with ordinal level data can compromise the understanding of the effects of the independent variables and of the ordinal level response. Provides applications with data from a multisite…

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…

The interest inventory of the Harrington-O'Shea Career Decision-Making System (T. F. Harrington & A. J. O'Shea, 1980, 1992, 2003) had hit rates of occupational status substantially exceeding chance expectations in the literature's 1st long-term predictive validity study since 1991. No significant gender differences were found for the Grade 10…

The study examined the component structure of the Relational Health Indices (B. Liang et al., 2002) with a mixed-sex sample of students seeking services at a university counseling center. In contrast to previous findings, results suggested a unidimensional structure for the peer and mentor composites and a 2-component structure for the community…

This study examined the reliability and validity of scores from the Multidimensional Inventory of Black Identity with 550 Euro-American, 112 Latino, and 41 Native American undergraduates. Data for the Centrality, Private Regard, and Public Regard scales indicate that these scores have construct validity. Scores have acceptable Cronbach alpha…
