Construct validity of the marital communication inventory.
The Marital Communication Inventory (MCI) is an extremely popular self-report measure of marital communication that has been used in over 65 dissertations and empirical articles since 1970, including several recent clinical reports that used the MCI as a principal outcome measure. However, contrary to its treatment in the clinical literature as a unidimensional, valid measure of treatment outcome, the MCI appears to be a multidimensional instrument, whose primary dimension may not be a specific style or method of communication. Using a canonical correlation analysis of data from over 200 midwestern wives, we compared MCI subscales with subscales from an abbreviated version of the Barrett-Lennard Relationship Inventory (RI). Results supported the hypothesis that the primary dimension of the MCI is more closely associated with positive regard than with the more specific communication dimensions of either empathy or congruence as measured by the RI. Future clinical research in the improvement of marital communication should use the MCI in a much more careful way in order to provide the most valid outcome data.
