Structural equation modeling (SEM) is one of the most rapidly growing analytic techniques in use today. Proponents of the approach have virtually declared the advent of a statistical revolution, while skeptics worry about the widespread misuse of complex and often poorly understood analytic methods. Despite the growing interest in and use of structural equation models, few individuals using these techniques have benefitted from any formal training. Indeed, most graduate programs provide no courses on SEM. Individuals interested in acquiring skills in this technique must eider attend expensive training seminars or plow through technical books and manuals on their own.
The two new books under renew are therefore timely. Both are valuable, but differ in important ways. Kevin Kelloway's book is directed at the researcher with little knowledge of structural equation modeling and is intricately linked to one of the more popular structural equation modeling programs, LISREL. For researchers keen to begin analyzing data quickly, this book is an invaluable resource that will speed one's introduction to SEM.
On the other hand, the volume written by Rex Kline represents one of the most comprehensive of available introductions to the application, execution, and interpretation of this technique. The book is written for both students and researchers who do not have extensive quantitative background. It is especially attentive to quantitative issues common to most structural equation applications.
Kelloway's book is designed for the researcher unfamiliar with structural equation modeling and structural equation software. Chapter 1 provides a brief overview of the book and differentiates among historical concepts such as path analysis and latent variable model. Although the focus of the book is on using LISREL, the book offers two of the most clearly written and concise introductory chapters on SEM that I have ever read. They provide an ideal introduction to the relevant basic concepts of the technique.
The theory behind the basic steps of structural equation modeling is reviewed in Chapter 2 and includes model specification, identification, estimation, testing fit, and respecification. The author emphasizes the importance of specifying the model. Indeed, this is the fundamental step in SEM that allows researchers to test hypotheses about the relation among a number of variables, and that makes structural equation modeling an inherently confirmatory technique.
