Family break-up is a common experience in childhood today, yet reports of its effects on children vary considerably. Variables to be considered are the age, sex and previous experiences of the child as well as the observer's viewpoint (clinician compared with social scientist): the need for well founded research is obvious. Divorce is a process affecting all family members: parent disharmony and quarrels prior to the divorce appear to be more detrimental to a child's adjustment than the separation itself which may represent a relief of tension. Behaviour and emotional problems following divorce relate to litigation regarding custody and access (accusations of sexual abuse during access are not uncommon), and a diminution of living standards. Feelings of rejection, depression, anger and guilt are frequent in the immediate post-divorce period, but settle during the ensuing year. Family counselling, individual work with children (especially explanations for younger ones) and social support in the post-divorce period are suggested as a means of combating long-term, sometimes lifelong, sequelae.
