A description of mentally ill parents' experience and points of view concerning professional intervention in relation to their young children is presented in this paper. The results are from an interview survey designed with the purpose of improving the basis for cooperation between mentally ill patients and professionals, when intervention in relation to these patients' children is needed. Fifty consecutively admitted psychiatric inpatients with children 0-10 years old were interviewed by child psychiatrists and their information constitutes the study material. Data concerning the family situations and children have been published previously. One quarter of the patients had experienced having children placed in institutions or with foster families. Forty per cent had never received professional help related to their children. One third of the patients expressed a need for support, which was not presently received. A large group of patients did not know where to go for help related to children or would not be comfortable doing so. When making a global assessment of the childrens' situation based on the study material the child psychiatrists found reason for concern in regard to approximately 80% of the children. In most cases their views were in accordance with those of the mentally ill parents. Clinical implications concerning planning of intervention in regard to children of mentally ill parents are discussed.
