Despite the considerable influence that multitrait/multimethod analysis and research strategies have had on scientific psychology, accessible texts fully integrating this framework into the assessment of complex psychological phenomena have been lacking, according to Eid (U. of Geneva, Switzerland) and Diener (U. of Illinois at Urbana-Champaign). They introduce 31 chapters filling theoretical, methodological, and applied gaps for students and researchers. Contributors address issues that need to be considered in: conducting ecologically valid field studies, convergent validity, and method selection for supporting validity. Finally, the editors recap contributors' messages that researchers need to learn about the newer sampling and testing methods, advances in statistics, and Web resources available; and apply multiple methods not just multiple measures.
