sessions following the FCU (14.5% at age 2, 13.8% at age 3, 12.7% at age 4, and 25.5% at age 5). Because of the low number of families that engaged in follow-up parenting services, it is difficult to analyze this aspect of engagement. Research on the use of the FCU for caregivers seeking help with an oppositional child would likely be the better context for evaluating the extent and nature of the follow-up sessions relevant to outcome.
