Stability of the ADI-R

Footnotes
1 Participants in the current study were selected from a sample of children who were
recruited as part of a longitudinal study investigating the effectiveness of early intervention in pre-
school children enrolled in either eclectic nurseries or home-based Early Intensive Behavioural
Intervention (EIBI) programmes (Magiati, Charman and Howlin, 2007), thus there is some overlap here
with the participants involved in that study. The current study was a longer follow-up study of these
participants focusing on stability and change of autism-specific symptomatology and behaviour over
time.
Mean scores are presented in the graphs for ease of reference, but analyses were
conducted using non-parametric techniques.
