Intelligence and personality in mate choice and marital satisfaction

This research examined how intellectual and personality similarity or complementarity between a couple relates to their marital choice and marital satisfaction. Eighty-one couples were tested using the WAIS-R and the MMPI and the Locke-Wallace Marital Adjustment Scale. As predicted, couples showed significant similarity for some IQ variables. However, the prediction that IQ would have a relationship to marital satisfaction was not borne out. Couples show some significant similarity on some personality variables but for different variables in the 39 Clinic couples and the 42 Non-clinic couples. A strong relationship was found between couples in both samples on the Pd scale. As far as marital satisfaction is concerned, similarity or complementarity in personality variables does not appear.
