From an original sample of 93 married couples 71 couples were selected according to criteria which determined how similar they were to their spouses on several personality variables. Specifically 3 groups of people were defined: a similar group who resembled their spouses highly in personality, a Random group who were neither positively or negatively matched with respect to personality measures and an Opposite group who tended to be opposite to their spouses on the personality measures. For each of these 3 groups, and for husbands and wives separately, scores on several marriage dimensions were compared. It was found that for both husbands and wives the Similar personality groups tended to score higher on the marriage role factor of Male Dominance than did either the Random or Opposite groups. For the wives data only, the Similar group also scored higher than the Random or Opposite groups on the marital factors of 1) Sexual Gratification and 2) Togetherness and Role Sharing. Possible implications and explanations for these findings are discussed.
