Divorce changes not only the spousal relationship, but other associations as well. To study the changes in the social networks of recently divorced individuals, 40 adults (20 males, 20 females) participated in structured interviews. During the interview, data were collected on respondents' social networks and on their psychological well-being before and following marital separation. The results showed that network turnover averaged 43% for men and 40% for women. Persons most likely to be dropped from the network were the spouse's relatives, persons the spouse had known first, cross-sex associates, and married friends. After separation, the network structure decreased in size and density, and became more segmented. Males tended to have more cross-sex close associates and tended to become involved in a new relationship sooner than women. Network interaction decreased in closeness for one-third of the respondents. Parents tended to have more stable networks than nonparents. Self-esteem was lower after separation, while life satisfaction and happiness gradually increased to levels as high or higher than during marriage. This improvement came more quickly for men than for women. (BL)
