Introduction to the Taxometric Method: A Practical Guide
Introduction to the Taxometric Method is a user-friendly, practical guide to taxometric research. Drawing from both classic and contemporary research, it provides a comprehensive introduction to the method. With helpful tools and guidance, the book is intended to teach those new to the method, as well as those already familiar with it, tips on how to conduct and evaluate taxometric investigations. The book covers a broad range of analytic techniques, describing their logic and implementation as well as what is known about their performance from systematic study. The book opens with the background material essential to understanding the research problems that the taxometric method addresses. The authors then explain the data requirements of taxometric analysis, the logic of each procedure, factors that can influence results and lead to misinterpretations, suggestions for choosing the best procedures, and methodological safeguards to prevent erroneous conclusions. Illustrative examples of each procedure and consistency test demonstrate how to perform analyses and interpret results using a variety of data sets. A checklist of conceptual and methodological issues that should be addressed in any investigation is included. The accompanying CD provides a variety of programs for performing taxometric analyses along with simulations and analyses of data sets. Introduction to the Taxometric Method is ideal for researchers and students conducting or evaluating taxometric studies in the social and behavioral sciences, especially those in clinical and personality psychology, as well as those in the physical sciences, education, biology, and beyond. The book also serves as a text for courses on this method, or as a supplement in psychological assessment, statistics, or research methods courses. Familiarity with taxometrics is not assumed..

Multivariate Taxometric Procedures: Distinguishing Types from Continua (Advanced Quantitative Techniques in the Social Sciences)
Can taxometric procedures be used to distinguish types (species, latent classes, taxa) from continua (dimensions, latent traits, factors); and, if so, how? Aimed at demystifying this process, Waller and Meehl unpack Meehl's work on the MAXCOV in simple terms and show how this technique can be profitably used in a variety of disciplines by researchers in their taxonomic work. The book begins with a discussion of the misconceptions concerning the psychometric and philosophical status of taxonic constructs; and, next reviews several meanings of the term 'taxon' and the philosophy of science that has guided the authors' work in this area. The authors then describe MAXCOV-HITMAX and demonstrate how MAXCOV uses the General Covariance Mixture Theorem to test taxonic hypotheses (using utility programmes in S-Plus that appear in the appendices to do the taxometric procedures). Using many clear examples and illustrations, they next introduce two new taxometric procedures, MAXEIG-HITMAX (MAXEIG) and L-Mode for the simultaneous analysis of multiple taxon indicators, and contrast these techniques with other data clustering and classification methods, such as latent profile analysis and Q-technique factor analysis. Lastly, they provide guidelines for corroborating taxonic models and describe the role of taxometrics in scientific methodology. .

Taxonicity of anxiety sensitivity: an empirical test among youth [An article from: Behaviour Research and Therapy]
This digital document is a journal article from Behaviour Research and Therapy, published by Elsevier in . The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: Taxometric coherent cut kinetic analyses were used to test the latent structure of anxiety sensitivity (AS) among 371 youth. Anxiety sensitivity was indexed by the 18-item Childhood Anxiety Sensitivity Index (CASI; Silverman et al., J. Clin. Child Psychol. (1991), 20, 162-168). Two sets of manifest indicators of AS were constructed using the CASI: (1) three item-parcel manifest indicators: disease concerns, unsteady concerns, and mental illness concerns; and (2) nine single-item indicators representing each of these three facets of AS. Results from standard and short-scale MAXCOV procedures, internal consistency tests, analyses of simulated Monte Carlo data, and MAMBAC external consistency tests indicated that the latent structure of anxiety sensitivity among youth was taxonic. Estimated base rate of the observed AS taxon ranged between 13.6 and 16.5%. The present findings are discussed in terms of theoretical implications for the study of AS and vulnerability for anxiety psychopathology. .
