This is achieved by calculating the square roots of the average variance extracted (AVE) values, which measure the average variance shared between a construct and its measures, and by calculating the correlations between different constructs. A matrix can then be constructed where the square root of AVE is in the diagonal, and the correlations between the constructs are in the off-diagonal. For adequate discriminant validity, the diagonal elements should be greater than the off-diagonal elements in the corresponding rows and columns (Fornell and Larcker 1981).
