Lessons on measuring construct validity: A commentary on Delis, Jacobson, Bondi, Hamilton, and Salmon

This commentary expands on issues raised by Delis, Jacobson, Bondi, Hamilton, and Salmon, in their paper on the use of shared variance techniques to establish construct validity. Significant discussion is focused on method variance, and how this can distort the results of factor analysis. Solutions are offered for the appropriate use of factor analysis in construct validation. Examples are also provided of construct validation procedures that do not rely on correlational or shared variance techniques. (JINS, 2003, 9, 947–953.)
