relationship. Moreno's ideas may have influenced some of the pioneers of family therapy, but also there were developments in general science, namely, cybernetic theory, developed in the mid-1940s, and noting the nature of circularity and feedback in complex systems. By the 1950s, the idea that relationships themselves could be problematic became quite apparent. So, diagnostically, in the sense not of naming a disease or disorder, but just helping people think through what was really going on, the idea of relational disorder was nothing new. Kinds The majority of research on relational disorders concerns three relationship systems: adult children and their parents, minor children and their parents, and the marital relationship. There is also an increasing body of research on problems in dyadic gay relationships and on problematic sibling relationships. Marital Marital disorders are divided into "Marital Conflict Disorder Without Violence" and "Marital Abuse Disorder (Marital Conflict Disorder With Violence)." Couples with marital disorders sometimes come to clinical attention because the couple recognize long-standing dissatisfaction with their marriage and come to the clinician on their own initiative or are referred by a health care professional. Secondly, there is serious violence in the marriage which is "usually the husband battering the wife". In these cases the emergency room or a legal authority often is the first to notify the clinician. Most importantly, marital violence "is a major risk factor for serious injury and even death and women in violent marriages are at much greater risk of being seriously injured or killed" (National Advisory Council on Violence Against Women 2000). The authors of this study add that "There is current considerable controversy over whether male-to-female marital violence is best regarded as a reflection of male psychopathology and control or whether there is an empirical base and clinical utility for conceptualizing these patterns as relational." Recommendations for clinicians making a diagnosis of "Marital Relational Disorder" should include the assessment of actual or "potential" male violence as regularly as they assess the potential for suicide in depressed patients. Further, "clinicians should not relax their vigilance after a battered wife leaves her husband, because some data suggest that the period immediately following a marital separation is the period of greatest risk for the women. Many men will stalk and batter their wives in an effort to get them to return or punish them for leaving. Initial assessments of the potential for violence in a marriage can
