Parent-Nominated Symptoms as an Outcome Measure in Autism Intervention ResearchVanessa DabelMentor: David S. Mandell, ScD

Project Overview

•Autism Instructional Methods Study (AIMS)▫3-hour battery of testing every September

and June•Apply Parent-Nominated Symptoms

strategy to a subset of subjects▫Students who are flooring

Hypothesis

•The parent-nominated symptoms measurement will be correlated with clinician ratings of improvement and will provide an ecologically valid, statistically reliable outcome measure for behavioral intervention trials

What are parent-nominated symptoms?•Symptoms that parents and caregivers

identify in their children that are of most concern to them

Significance• It is difficult to measure symptoms and

changes in symptoms over time for a group of children with ASD using a single measure▫Standardized scales may fail to reflect real

change important to the individual family (Arnold et al., 2003)

•Addition of parent-targeted symptoms questionnaire in pharmacological studies proved to be successful (Arnold et al., 2003)

•Ecological validity

Aims

•To seek information from parents for which clinicians may rate in order to track the changes in Parent-Nominated Symptoms▫to turn qualitative data into a quantitative

measure•To test the feasibility of refining and

replicating this strategy in a behavioral study

Methods

•Conduct phone interviews in August and November 2009▫Questions focused on communicative and

social impairments as well as maladaptive behaviors “How often?” “How long each time?” “How

many hours a day?” “How does it interfere with daily activities?”

•Select group of clinicians to rate the symptoms▫Qualitative data Quantitative measure▫Examine whether there is change over time

My Role

•Drafting documents to be submitted for IRB approval▫Project Description, Verbal Consent Form,

Phone Script•Responsible for conducting phone

interviews with parents and caregivers ▫Verbal consent

•Collecting and analyzing data

Lessons Learned

•Becoming more familiar with the IRB process

•Gaining more experience in conducting autism research▫Better understanding of the measures that

are used•Exploring research interests as they

pertain to my professional development
