Toward improving outcomes from early intervention for vulnerable children: pilot RCT of a new treatment for non-responders to parent training for conduct problems

BackgroundChildren with conduct problems are at high risk of a wide range of mental health problems in later life, making them a priority for early intervention. Group-based parent-training is known to be effective but with a substantial failure rate. Based on evidence on the value of involving children, we developed Reflective Interpersonal Therapy for Children and Parents, (RICAP). We report here, feasibility and outcomes from the first trial of an intervention for children with conduct problems persisting after parent training. In contrast to most other studies, we used both parent and teacher report. MethodsThe sample comprised 105 children and their parents aged 5-10 years referred to UK Child and Adolescent Mental Health Services (CAMHS) with conduct problems. All were offered the Incredible Years (IY) parent training intervention, and parents provided pre- and post-treatment measures (including CBCL, SDQ). Children still above clinical threshold after IY were randomized either to RICAP or to usual CAMHS treatment (CTAU) with follow up 8 months later. Trial Registration Number: ISRCTN25252940. ResultsFeasibility was supported by high retention through the initial IY (102/105) and subsequent RCT phases of the study (58/70 eligible for randomization). The majority of those randomized to RICAP attended for 11/14 or more sessions, reflecting its high acceptability to both children and parents. By parent report RICAP was superior to CTAU on CBCL externalising (d=0.32) and internalising (d=0.42) problems, while by teacher report CTAU was superior on SDQ total problems (d=0.32) and reactive aggression (d = 0.27). ConclusionsWe provide first evidence of the acceptability and effectiveness of a novel intervention for children with persisting conduct problem following parent training. We also find differences between parent and teacher reported outcomes, pointing either to reporter or social context effects, both of which need to be addressed in future research.
