Synopsis

This book approaches copy testing from the perspective of psychometrics, specifically examining the reliability of the advertising measurement procedure, scrutinizing test-retest correlation as a measure of reliability. The author argues that the field has historically neglected the importance of a standardized measurement model when interpreting test-retest correlations and cautions that failure to adhere to such a model can obscure the true meaning of reliability. Practical examples are given to illustrate the importance of satisfying certain key reliability conditions such as the stability of true scores across replications and the absence of idiosyncratic non-compensating changes in true scores. By illuminating the potential pitfalls and complexities of reliability assessment, this book provides valuable insights for researchers and practitioners seeking to make informed decisions about the validity of their copy testing methods.
