Does the stability of personality vary by gender or ethnicity? Does a particular therapy work better to treat clients with one type of personality disorder than those with another? Aimed at providing a solution to thorny problems such as these, Aguinis shows readers how to better assess whether the relationship between two variables is moderated by group membership through the use of a statistical technique, moderated multiple regression (MMR). Clearly written so that readers need only have a basic knowledge of inferential statistics to access it, the book and its associated computer programs and data sets (available on the web) will help students, researchers, and practitioners determine whether a particular intervention is likely to yield dissimilar outcomes for members of various groups.
