be supplemented by standardized interviews and questionnaires, which have been reliable and valid aids in exploring marital violence more systematically." The authors conclude with what they call "very recent information" on the course of violent marriages which suggests that "over time a husband's battering may abate somewhat, but perhaps because he has successfully intimidated his wife." The risk of violence remains strong in a marriage in which it has been a feature in the past. Thus, treatment is essential here; the clinician cannot just wait and watch. The most urgent clinical priority is the protection of the wife because she is the one most frequently at risk, and clinicians must be aware that supporting assertiveness by a battered wife may lead to more beatings or even death. In some cases, men are abuse victims of their wives; there is not exclusively male-on-female physical violence, although this is more common than female-on-male violence. Parent–child abuse Research on parent–child abuse bears similarities to that on marital violence, with the defining characteristic of the disorder being physical aggression by a parent toward a child. The disorder is frequently concealed by parent and child, but may come to the attention of the clinician in several ways, from emergency room medical staff to reports from child protection services. Some features of abusive parent–child relationships that serve as a starting point for classification include: (a) the parent is physically aggressive with a child, often producing physical injury, (b) parent–child interaction is coercive, and parents are quick to react to provocations with aggressive responses, and children often reciprocate aggression, (c) parents do not respond effectively to positive or prosocial behavior in the child, (d) parents do not engage in discussion about emotions, (e) parent engages in deficient play behavior, ignores the child, rarely initiates play, and does little teaching, (f) children are insecurely attached and, where mothers have a history of physical abuse, show distinctive patterns of disorganized attachment, and (g) parents relationship shows coercive marital interaction patterns. Defining the relational aspects of these disorders can have important consequences. For example, in the case of early appearing feeding disorders, attention to relational problems may help delineate different types of clinical problems within an otherwise broad category. In the case of conduct disorder, the relational problems may be so central to the maintenance, if not the etiology, of the disorder that effective treatment may be impossible without recognizing
