A multitrait-multimethod matrix is the most useful tool in evaluating convergent and discriminant validity evidence. This matrix examines the correlations between two or more constructs measured using different methods (such as self-report and observation) to determine if they converge (correlate highly) or discriminate (correlate low or not at all). This approach is considered the gold standard for evaluating construct validity. The Rulon formula, Greco-Latin squares design, and abacus are not relevant tools for evaluating validity evidence.
