New book unleashes secrets to using a powerful data reduction technique

In an attempt to make research easier for everybody, Drs. Frank Walkey and Garry Welch collaborate to bring a highly informative book. Demystifying Factor Analysis: How It Works and How To Use It, an Xlibris release, provides readers with insights into the practical use of factor analysis through clear and readable text with illustrative examples.

A must-learn topic in graduate-level statistics, factor analysis is a statistical technique designed to help researchers explore patterns of correlations among variables of interest in education, psychology, and medicine and other data-driven fields of research limited only by the imagination of the researcher. It is a tool used to discover underlying latent variables that will provide conceptual insights and improve measurement strategies. A well-written book, Demystifying Factor Analysis essentially explains factor analysis, discusses some problem areas historically associated with the technique, and provides an improved approach that addresses the problem areas. The authors, through in-depth discussion yet conversational tone, explain key concepts for interpreting the parameters that are relevant for evaluating the factor analytic results. To complement the edifying book, they also provide a new web-based tool that responds to the important need to document the replicability of the factor solution (

Factor analysis is a powerful data reduction technique. Demystifying Factor Analysis: How It Works and How To Use It offers effective tips to help maximize the key role of factor analysis: reduce the potentially confusing pattern of correlations obtained from a larger set of variable to a simpler, yet illuminating reduced set of underlying or hypothesized variables.

His special interest has been in the application of factor analysis to psychological measurement.

Garry Welch, Ph.D., is a behavioral medicine researcher and Director of Behavioral Medicine Research at Baystate Medical Center, Springfield, MA. He is Research Associate Professor at Tufts University School of Medicine and was a reviewer for five years on the Behavioral Medicine Interventions and Outcomes (BMIO) grants review committee at the National Institutes of Health. His research interests include the behavioral and medical management of chronic medical conditions such as type-2 diabetes and obesity, as well as the use of telemedicine and patient-centered interventions for patients with these conditions. He began his research career as a doctoral fellow interested in psychometrics and behavioral medicine under the mentorship of Dr. Walkey in New Zealand. He has a long standing interest in the use of factor analysis to evaluate measures of health-related quality of life and psychological adjustment.
