Abstract
The aim of the study was to develop a newly devised child observation sheet (COS-5)
as a scoring sheet, based on the Childhood Autism Rating Scale (CARS), for use in
the developmental evaluation of 5-year-old children, especially focusing on children
with autistic features, and to verify its validity. Seventy-six children were studied.
The children were recruited among participants of the Japan Children’s Cohort Study,
a research program implemented by the Research Institute of Science and Technology
for Society (RISTEX) from 2004 to 2009. The developmental evaluation procedure was
performed by doctors, clinical psychologists, and public health nurses. The COS-5
was also partly based on the Kyoto Scale of Psychological Development 2001 (Kyoto
Scale 2001). Further, the Developmental Disorders Screening Questionnaire for 5-Years-Olds,
PDD-Autism Society Japan Rating Scale (PARS), doctor interview questions and neurological
examination for 5-year-old children, and the Draw-a-Man Test (DAM) were used as evaluation
scales. Eighteen (25.4%) children were rated as Suspected, including Suspected PDD,
Suspected ADHD and Suspected MR. The COS-5 was suggested to be valid with favorable
reliability (α = 0.89) and correlation with other evaluation scales. The COS-5 may be useful, with
the following advantages: it can be performed within a shorter time frame; it facilitates
the maintenance of observation quality; it facilitates sharing information with other
professions; and it is reliable to identify the autistic features of 5-year-old children.
In order to verify its wider applications including the screening of infants (18 months to 3 years old) by adjusting the items of younger age, additional study is needed.
