Divorce and destructive couple conflict are major risk factors for many forms of dysfunction and psychopathology in the family. Couple relationship education has been offered in an attempt to reduce those risks and enhance couple outcomes. The current effectiveness study had two aims: to assess (a) the long-term effects of relationship education and (b) the ability of partners to remember the skills typically taught during the communication skills training. One hundred and one couples from two studies, in which the effectiveness of the EPL (Ein Partnerschaftliches Lernprogramm für Paare [A Learning Program for Married Couples]) was investigated, were followed-up 11 years after the training. In the first study, EPL-takers had a significantly lower divorce and separation rate (27.5%) than non-EPL-takers (52.6%). This finding was replicated in a second study, showing a 20% dissolution rate in EPL-takers. For those couples still together, the rate of happy relationships was 80% at the eleven-year follow-up - thus, there is optimism for longer married couples who are willing to focus on improving their relationships. Only about 55% of the partners could remember at least one speaker skill whereas 70% remembered at least one listening skill taught during EPL. Consequences for prevention programs in the couple domain are discussed.
