This report describes the development of The Physician's Developmental Quick Screen for Speech Disorders (the PDQ), a screening test designed for use by nonspeech pathologists with children aged six months to six years. Disorders of language, articulation, voice, rhythm of speech, and the speaking mechanism are considered by the PDQ. Validation studies resulted in 90 per cent agreement (p < .001) between nonspeech pathologists utilizing the PDQ and speech pathologists employing a battery of more established tests.
