We describe a distress prevention training program for couples and three empirical studies that support its effectiveness. The program, Couples Coping Enhancement Training (CCET), is based both upon stress and coping theory and research on couples. In addition to traditional elements of couples programs (e.g., communication and problem-solving skills), the CCET also addresses individual and dyadic coping in promoting marital satisfaction and reducing marital distress. The CCET enjoys good consumer acceptance. Outcome results indicate that, in addition to acquiring relationship skills, participants experienced reduced martial distress and increased marital satisfaction, even among couples who have been in long-standing relationships where dissatisfaction exists.
