Similarly, all authors and subjects involved in this study declared themselves free of any conflict of interest relating to the study. All respondents participated in this study without any incentive. The purpose of this study was clearly stated on the face sheet of the questionnaire answering the questionnaire was deemed to be consent.

The site investigators either physically distributed questionnaires to their colleagues or sent emails providing colleagues with the questionnaire's URL plus a login password. Questionnaires were mailed to site investigators at the collaborating institutes. The authors provided three options for answering the questionnaire: online, email, or conventional mail. All participants completed the questionnaire during the study period from July 1 to August 31, 2008. These participants numbered 50 psychiatrists, 5 pediatricians (whose subspecialty was child psychiatry), and 149 non-medical doctors, most of whom were working at child guidance centers. The subjects of this study were 205 medical and social welfare professionals working in fields relating to developmental disorders. In this study, we surveyed the perception of autism and related conditions as a clinical entity and attitudes toward terminology on these disorders among medical and social welfare staffs in this field. The diversity among the definitions of ASD and the disparate terms for autistic disorders could be factors that confuse not only the subjects with PDD and their families but also medical and welfare professionals. Furthermore, clinicians worldwide have frequently used the term ASD. However, the terms used in these two widely accepted diagnostic systems to describe subcategories in PDD are not identical. 3, 9 The criteria described in both the ICD-10 and the DSM-IV closely resemble each other, and both diagnostic systems use the term PDD. In clinical practice, several different diagnostic criteria have been used, including the ICD-10 and DSM-IV, 4 as well as Kanner's, 5, 6 Gillberg's, 7, 8 and Wing's criteria. The diagnostic criteria for autistic conditions have been controversial. Wing regards these conditions as one continuous clinical entity. 2, 3 In her view, ASD encompasses disorders ranging from severe autism with profound mental retardation to high-functioning autism and Asperger's syndrome. The concept of the autism spectrum disorders (ASD) was proposed by Lorna Wing. 1 Pervasive developmental disorders are a condition characterized by a clinical triad of impairment in social interactions impairment in communications and a restricted repertoire of activity and interests. The term pervasive developmental disorders (PDD) first appeared in the ICD-10 in 1992.
