The obvious gaps in available outcome measurement include well-being and participation outcomes for children , and family quality -of-life outcomes , domains particularly valued by our informants ( young people with ASD and parents ) .

BACKGROUND The needs of children with autism spectrum disorder ( ASD ) are complex and this is reflected in the number and diversity of outcomes assessed and measurement tools used to collect evidence about children 's progress .
Relevant outcomes include improvement in core ASD impairments , such as communication , social awareness , sensory sensitivities and repetitiveness ; skills such as social functioning and play ; participation outcomes such as social inclusion ; and parent and family impact .
OBJECTIVES To examine the measurement properties of tools used to measure progress and outcomes in children with ASD up to the age of 6 years .
To identify outcome areas regarded as important by people with ASD and parents .
A prospective study of autistic-like traits in unaffected siblings of probands with autism spectrum disorder.
CONTEXT The presence of autistic-like traits in relatives of individuals with autism spectrum disorder ( ASD ) is well recognized , but , to our knowledge , the emergence of these traits early in development has not been studied . OBJECTIVE To prospect ively investigate the emergence of autistic-like traits in unaffected ( no ASD diagnosis ) infant siblings of prob and s diagnosed as having ASD . DESIGN Two groups of children unaffected with ASD were assessed prospect ively-siblings of prob and s diagnosed as having ASD ( high risk [ HR ] ) and control subjects with no family history of ASD ( low risk [ LR ] ) . Scores on a measure of autistic-like traits at 12 months of age were used in a cluster analysis of the entire sample . SETTING A prospect i ve study of infant siblings of prob and s with ASD from 3 diagnostic centers in Canada . PARTICIPANTS The study included 170 HR and 90 LR children , none of whom was diagnosed as having ASD at age 3 years . MAIN OUTCOME MEASURES The Autism Observation Scale for Infants was used to measure autistic-like traits and derive clusters at 12 months of age . Clusters were compared on ASD symptoms , cognitive abilities , and social-emotional difficulties at age 3 years . RESULTS Two clusters were identified . Cluster 1 ( n = 37 ; 14.2 % of total sample ) had significantly higher levels of autistic-like traits compared with cluster 2 . Within cluster 1 , 33 children came from the siblings ( 19.4 % of HR group ) and only 4 came from the control subjects ( 4.5 % of LR group ) . At age 3 years , children from cluster 1 had more social-communication impairment ( effect size > 0.70 ; P < .001 ) , lower cognitive abilities ( effect size = -0.59 ; P < .005 ) , and more internalizing problems ( effect size = 0.55 ; P = .01 ) . Compared with control subjects , HR siblings had a relative risk of 4.3 ( 95 % CI,1.6 - 11.9 ) for membership in cluster 1 . CONCLUSIONS Study findings suggest the emergence of autistic-like traits resembling a broader autism phenotype by 12 months of age in approximately 19 % of HR siblings who did not meet ASD diagnostic criteria at age 3 years
