Abstract
This research is applied research and aims to improve the training course administration
of Thai Diagnostic Autism Scale (TDAS) in the context of secondary and tertiary health care services and develop prototype models for implementing TDAS tools for useable innovations. The trial was conducted in 13 secondary and tertiary health care services with a sample size of 382 children between the ages of 12 and 48 months with suspected autism, found that 317 cases, representing 82.98 percent, had autism. All multidisciplinary staff, were found to have a very good level of post-training administration skills. Additionally, children at risk of delayed development in Expressive language (EL), Receptive language (RL) and Personal and Social (PS) ,results indicated that a delay in one of these domains had a statistically significant proportion of autism greater than 0.5 at the .01 level. At the secondary and the tertiary level, the multidisciplinary health care service teams prioritize centralized policy, leadership of the hospital director, personnel, and the multidisciplinary team. A major obstacle to providing local autism services is the waiting time for diagnostic services, continuing therapy. As well as the awareness and collaborative participation of parents. This research suggests the Ministry of Public Health that to simplify and shorten the waiting time for diagnose a child with autism, the revision of the care mapping of early childhood care is needed. As a result of the revision, a child can access the treatment process 6-12 months sooner than the present system allows.
