Participants. The investigators will recruit enough participants to have 60 caregivers complete the post-treatment (3 month) assessment in each of 4 RCTs. Given the likelihood of overlap in diagnoses across groups, participants will be enrolled based on their primary and most impairing disorder. The intervention will be designed for children with mild-to-moderate disabilities, as it is expected that children with severe neurologic disease will not benefit from this type of intervention.
