Analyzing The Multitrait-Multimethod Matrix |
| |
Abstract: | The heuristic strategy proposed by Campbell and Fiske for investigating convergent and discriminant validity is rephrased within a more precise statistical framework. First of all, several indices are defined that mirror the properties within a multitrait-multimethod matrix that are supposed to reflect the two notions of validity. Then, based on a simple nonparametric model, a general significance testing procedure is developed that may be used to evaluate the size of each index. Although the suggested inference technique does add a formal structure to the intuitive methods advocated by Campbell and Fiske, the intent of the discussion remains close to their original philosophy. |
