A pilot randomised control trial of a parent training intervention for pre-school children with autism

Abstract . Few attempts have been made to conduct r and omised control trials ( RCTs ) of interventions for pre-school children with autism . We report findings of a pilot RCT for a parent training intervention with a focus on the development of joint attention skills and joint action routines . Twenty-four children meeting ICD-10 criteria for childhood autism ( mean age = 23 months ) were identified using the CHAT screen and r and omised to the parent training group or to local services only . A follow-up was conducted 12 months later ( mean age = 35 months ) . There was some evidence that the parent training group made more progress in language development than the local services group . However , the present pilot study was compromised by several factors : a reliance on parental report to measure language , non-matching of the groups on initial IQ , and a lack of systematic checking regarding the implementation of the parent training intervention . Furthermore , three parents in the local services group commenced intensive , home-based behavioural intervention during the course of the study . The difficulties encountered in the conduct of RCTs for pre-school children with autism are discussed . Method ological challenges and strategies for future well- design ed RCTs for autism interventions are highlighted
An increasing number of interventions have some empirical support ; others are emerging as potentially efficacious .
