Although social networks play an important role in supporting families under stress, there is some evidence that families living a stressful dual career life style may have limited network resources. To describe support networks of dual career couples and to examine the relationship between the supportiveness of the network and satisfaction with the marriage and life style, 52 dual career couples completed a mail survey. Participants were recruited from a large university faculty, were well educated, and had been married an average of 18 years. The questionnaire consisted of questions about satisfaction with the marriage and life style, satisfaction with the support network, and demographics. Results indicated that, in general, members of the support network comprised a heterogeneous group. The networks contained relatives, co-workers and friends, other dual career couples as well as single provider couples, and opposite-sex as well as same-sex individuals. Analysis of the relationship between supportiveness and satisfaction showed husbands were more satisfied when their networks were perceived to be supportive, while wives were more satisfied when their networks were perceived as close and satisfying. Limited frequency of contact and distance did not hamper the maintenance of supportive relationships. Results indicate the importance of the quality and supportiveness of the network for satisfaction. (JAC)
