Developmental trajectories of adaptive behaviors from early childhood to adolescence in a cohort of 152 children with autism spectrum disorders.

This study examines change in 152 children over an almost 10-year period (T1: 4.9 (± 1.3) years; T2: 8.

Outcome of young children with autism: does the amount of intervention influence developmental trajectories?

The study aims were to identify developmental trajectories of young children with autism and investigate their prognostic factors. The participants were 208 children, assessed first at the age of 5 years, followed longitudinally, and reassessed 3 years later. The children's clinical characteristics and the interventions received were recorded.

Initial characteristics of psychological development and evolution of the young autistic child.

This longitudinal study assessed multidisciplinary data on 219 children with autistic spectrum disorders from the median age of 5 (Time 1) to 8 years old (Time 2). The evolution of psychological and adaptive data was subjected to cluster analysis. Four clinically meaningful clusters emerged.

Relationship between age of recognition of first disturbances and severity in young children with autism.

Autism is now thought to be present right from birth. Although usually not officially diagnosed until after the child's second birthday, parents often report disturbances before then. The age of detection of disturbances varies and may be linked to differences in the severity of the autism and its associated retardation.
