State officials and parent advocates gave different versions Tuesday of how often, and why, the Department of Children and Families (DCF) takes custody of children with severe behavioral health problems – and whether the practice should continue. Advocates, including a group of adoptive parents, told the legislature’s Committee on Children that a proposed bill that would prohibit DCF from “requesting, recommending or requiring” that parents relinquish their custodial rights when seeking mental health treatment for their children is needed to stop a practice known as ‘trading custody for care.’ The bill, drafted by state Rep. Rosa Rebimbas, R-Naugatuck, was prompted by an October C-HIT story that described DCF’s use of “uncared for” custody petitions against parents who could not manage their children at home and insisted on specialized residential care. In testimony Tuesday, DCF Commissioner Joette Katz said the agency resorts to taking over custody only in rare cases in which parents refuse to take their children home from inpatient settings or “will not cooperate” with clinician-recommended in-home or community-based treatment services. “We disagree with the notion that DCF requires parents to completely relinquish custody of their children” to receive suitable behavioral health care, Katz said. She acknowledged that the agency has sharply reduced the number of children it places in residential treatment.
