Children with acquired brain injury (ABI) are at risk of impairments in self-regulation and disruptive behavior. We aimed to investigate the effectiveness of the Signposts program to reduce disruptive behavior and improve self-regulation in Hispanic children with ABI, and reduce parental stress and improve parenting practices. Using a randomized controlled trial design, we assigned children (n = 71) and their parents to Signposts or generic telephone support. Blinded assessors conducted assessments at pre-intervention, immediately post-intervention, and at 3 months post-intervention. Signposts was effective in reducing dysfunctional parenting practices. Further, when analyzing participants at risk of behavioral disturbance (n = 46), Signposts was effective in reducing child disruptive behavior in the home environment and emotional self-regulation. No differences were found for parental stress, parent sense of competence, child disruptive behaviors at school, and child cognitive and behavioral selfregulation. The reduction in disruptive behavior was associated with the implementation of authoritative parenting practices (external regulation), and not associated with child self-regulation. ARTICLE HISTORY

The study of rehabilitation for executive dysfunction in children with ABI is emerging. Although few high-quality intervention studies exist in this area, which limits conclusions regarding intervention efficacy, results of existing studies suggest that education for parents may be an important component of intervention. Moreover, caregiver involvement may improve the effectiveness of hot EFs rehabilitation interventions, while high intervention session frequency may be important in improving cold EFs. Positive behavior supports and specific training based on a cognitive model provided some promising findings, which require further evaluation.

These results support using qualitative analysis for recall strategies, since the technique provides data about which components of the task are affected by brain damage. Clusters depend on the integrity of semantic memory, while switching has to do with developing effective search strategies, cognitive flexibility, and the ability to modify responses. Frontal lobe damage has been reported in MS, and this is consistent with results from the phonological VF test.
