Sixteen young married couples completed the Jenkins Activity Survey and a questionnaire dealing with the temporal parameters of marital communication, work around the home, social activity, relaxation, and marital sex. In general, it was found that the coronary‐prone behavior pattern has negative implications for the interpersonal and leisurely activity of Type As and their spouses. As Type A characteristics increase, males communicate less with their wives, work more around the home, and engage in less marital sex.

For both sexes, those high on the Type A dimension are most likely to report that they derive relatively little pleasure from socializing. Several differences are also reported as a function of spouse standing on the Type A‐B dime
