A family with a severely multiple-handicapped child should be treated rather as an integrated family than as a pair of mother and child. From this view-point we talked with the five pairs of parents who participated in our group-therapeutic practice, and examined each case. The fathers became motivated by the development of their children and the changes of their wives through this group-therapeutic practice and actively attended our practices. The following five steps to facilitate fathers' attendance have been found: (1) letting them to know growth of children, mental security of mothers, and repairment of their interactions, (2) orientating them to our practices, (3) giving them chances of attending our practices, (4) discussing our practice with them and enhancing their motivation for participation, (5) making chances of associating with each family. The following three factors are presumed as the approach to the fathers. (1) Self-awareness of the father role. (2) Deeping their knowledge of role. (3) A chance to change their family dynamics. It seems that the fathers have become conscious of their existence as the father with a handicapped child through the association with other families and the contacts with the therapists. It also seems that the father's changes may have guaranteed their wives more mental security, too. We came to the conclusion that fathers' participation activates and stabilizes their marital relationship and family dynamics, centering their handicapped children.
