Pervasive Developmental Disorders Screening Test – Second Edition (PDDST-II)

The Pervasive Developmental Disorders Screening Test – Second Edition (PDDST-II; Siegel, 2004) is a questionnaire designed to screen for autism in young children from 12 to 48 months of age.

Overview

Three versions were developed for different settings, referred to as stages: Stage 1: Primary Care Screener; Stage 2: Developmental Clinic Screener; and Stage 3: Autism Clinic Severity Screener. Stage one is intended for primary care settings. Stage two is intended for children who are receiving developmental services, and stage three is designed to help differentiate autism from other pervasive developmental disorders. The PDDST-II may be administered to parents/caregivers as a questionnaire or given in an interview format. Results are interpreted by a clinician.
