Developing and Evaluating a Parent-child Intervention for Intellectually Able Children With Autism Spectrum Disorders: A Feasibility Study

Brief Summary

Detailed Description

Over recent years a growing body of research has reported significant, beneficial effects of using an "elaborative reminiscence" (ER) intervention on a range of typically-developing child outcomes including memory language skills, emotional understanding and understanding of mind. A recently published 9- year follow-up study further indicates that these benefits are longstanding. This has prompted speculation that ER could be a beneficial intervention for children with neurodevelopmental disorders who have known difficulties in these areas. To date, no studies have assessed the benefits of using ER as an intervention for ASD. This study aims to evaluate the feasibility, acceptability and preliminary effectiveness of training parents to use ER as an intervention for high-functioning children with ASD. This study will use a two-arm, parallel-group, randomised controlled design to compare a parent-delivered ER intervention against a control intervention (present tense talk). Fifty parent-child dyads (comprising children with ASD and IQ \>70) will be recruited from mainstream schools, specialist unit/ schools, or relevant organisations (25 dyads per trial arm). Primary outcomes will be NIHR-recognised quantitative indicators of feasibility and acceptability for the ER condition.This will include (yet is not limited to) exploring the feasibility of methods of recruiting participants, feasibility of administering outcome assessments at baseline and follow-up, feasibility of delivering the training for ER and PTT remotely (i.e. through video conferencing), the feasibility of parents delivering ER or PTT in their home setting, and the acceptability of ER to parents. Parent acceptability of ER will be assessed using a daily logbook questionnaire and post-trial interviews, based on the Theoretical Framework of Acceptability. Secondary outcomes will be measures of clinical and functional outcomes for both experimental conditions. Descriptive measures of general intelligence, vocabulary and developmental level will be administered at baseline for both experimental conditions (ER and PTT) and used to describe the participant sample. Outcome measures for child memory, mental state understanding, and self-concept will be administered at baseline and again after 20 weeks to assess change or response to the interventions. Differences in parent reminiscing style from baseline to post-trial will be assessed for all participants to assess the success of intervention training. On completion of follow-up outcome assessments, parents in the ER condition will be invited to participate in a single qualitative interview to evaluate the acceptability of the ER intervention and study procedures. Interviews will be based on the Theoretical Framework of Acceptability and the Necessity-Concerns Framework. Descriptive statistics will be taken for indicators of intervention feasibility and acceptability.Comparisons between the two trial arms will be made using inferential statistical analysis for multiple outcomes, whilst adjusting for covariates. In response to the present Covid-19 situation, this study will take place remotely. All interaction with participants (recruitment and data collection and participant testing) will use video software (e.g. Zoom, AdobeConnect, MS Teams), or online surveys (e.g. Qualtrics). Data analysis will either take place in the Autism Research Unit laboratory, located at City University of London, or remotely via a secure network.
