 A behavior checklist, the Pervasive Developmental Disorder (PDD)─Autism Society Japan Rating Scale (PARS), was developed as a screening questionnaire to determine Pervasive Developmental Disorders (PDDs) and also as a rating scale to evaluate the severity of a wide range of PDD symptoms. When assessing adolescents and adults using the PARS for these purposes, 34 toddlerhood items are evaluated retrospectively and 33 items are used for current evaluation. In this study, the reliability and validity of the PARS was tested on a clinical sample of 53 adolescents and adults with PDD and 42 with non-PDD diagnoses. Interrater and internal reliability was found to be adequate. Both the 34 toddlerhood evaluation items and the 33 current evaluation items accurately discriminated PDD from non-PDD. Results suggested that the PARS may be a useful screening scale for various clinical settings.
