dc.description.abstract | The current study represents a preliminary investigation of a new screening measure, the
Vanderbilt Scales for Autism Spectrum Disorder (ASD). This measure’s psychometric
performance in toddlers referred for developmental evaluation (N=159, ages 18-36
months) was compared to the most common screening measure (i.e., the Modified
Checklist for Autism in Toddlers [M-CHAT]) and a structured observation of behavior.
Results indicated that the Vanderbilt Scales had a lower sensitivity than the M-CHAT,
but a higher specificity and positive predictive value. Adding a structured observation of
behavior resulted in a higher positive predictive value than when either respective
screening measure was used alone. Results highlight the limits of self-report screening
measures and the potential value of hybrid screening methodologies utilizing parent
report and structured observations. | en_US |
