Multitrait-multimethod analysis in psychotherapy research: New methodological approaches
Taylor & Francis
Multimethod measurement plays a crucial role in psychology to analyze the convergent and discriminant validity, estimate the degree of method specificity, and scrutinize the generalizability of results of empirical studies and assessment procedures across methods. The implications of multimethod approaches for test validation, multimethod measurement, indication, and evaluation in psychotherapy research are discussed. Moreover, an overview of modern methodological approaches of multitrait-multimethod analysis for cross-sectional and longitudinal data is given. In particular, basic principles of confirmatory factor analysis models for interchangeable and structurally different methods are explained.
