Response Inhibition Training for Children With Williams Syndrome

Study Overview
=================
Brief Summary
-----------------
The investigators will conduct a pilot study investigating the effectiveness of a computerized response inhibition training program at reducing the response inhibition difficulties often seen in children with Williams syndrome ages 10-17. The investigators hypothesize that after completing the training program, children with Williams syndrome will show improvement on computerized measures of response inhibition and on parent measures of impulsivity.

Detailed Description
-----------------
Behavioral characteristics of individuals with Williams syndrome include eagerness to approach and interact with others (including strangers), repeated questions especially about upcoming events, and difficulties with attention, impulsivity, and inhibition. There is very little systematic research about the kinds of interventions that are most useful for children with Williams syndrome to support optimal psychosocial functioning, and of the effectiveness of such interventions. We will conduct a pilot study of a potential intervention to address the response inhibition difficulties associated with Williams syndrome. The investigators will examine the utility of an online, web-based computerized cognitive retraining program aimed at addressing impulsivity and inhibition difficulties in 20 children, ages 10-17, with WS. The engaging training program has shown some utility in other populations, including children with tic disorders and trichotillomania. The investigators will examine the acceptability and feasibility of the treatment approach, as well as its impact on performance on experimental measures of impulsivity and on everyday psychosocial functioning as rated by parents; this study will consist of a small-scale pilot Randomized Clinical Trial with wait list. Through this novel work, we hope to develop and tune this approach for optimal outcomes and to demonstrate the promise of this intervention to address common challenges of people with Williams syndrome in the area of inhibition.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cognitive Inhibition Tasks | Three measures of response inhibition that were administered to children at pre-test will be administered after the 5-7-week training and again at a 3-month follow-up. Measures include computer-administered Motor Stroop task, Stop Signal task, and Go/No-Go Task. | 5-7 weeks and 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Conners-3 | The Conners-3 will be administered to parents at post-intervention and again at follow-up to assess changes in attention and impulsivity. | 5-7 weeks and 3 months | 
| Emotion Regulation Checklist | The Emotion Regulation Checklist will be administered to parents at post-intervention and follow-up to assess changes in the child's ability to regulate emotions. | 5-7 weeks and 3 months | 
| Positive and Negative Affect Scale | The PANAS will be administered to parents at post-intervention and follow-up to assess changes in child positive and negative affect. | 5-7 weeks and 3 months | 
| Question-Asking Questionnaire | The QAQ will be administered to parents at post-intervention and follow-up to assess changes in amount and frequency of child anticipatory question asking. | 5-7 weeks and 3 months | 
| Spence Children's Anxiety Scale | The SCAS will be administered to parents at post-intervention and follow-up to assess changes in child anxieties. | 5-7 weeks, 3 months | 
| MINI Kid 6.0 Parent Version | The MINI Kid 6.0 Parent will be administered to parents at post-intervention and follow-up to assess changes in those areas endorsed at pre-intervention. | 5-7 weeks and 3 months |
