Screening Test for Developmental Apraxia of Speech: Examiner's manual (STDAS-2) & Profile Examiner/Record Form Paperback Binding – (Complete KIT)
By Robert W Blakely (Author)
The Screening Test for Developmental Apraxia of Speech (STDAS), published in 1980, was the first instrument developed to screen for the potential presence of developmental apraxia of speech in children. Since the development of the STDAS, only one other instrument has been developed to assist in the diagnosis of developmental apraxia of speech. Given the paucity of instruments, I found it important to revise and update the STDAS to meet the needs of contemporary speech-language pathologists. The purpose of this preface is to briefly review how the STDAS was developed, to share the one critical review that has been written about the test, and to describe the characteristics and new features of the revision.
An Overview of the Earlier Edition of the STDAS
For the past 20 years, the STDAS has proven helpful in identifying children ages 4 through 12 with atypical speech-language problems and associated oral performance. These are two key factors that render children suspect for developmental apraxia of
Speech. The first edition of the test had eight sub-texts: Expressive Language Discrepancy, Vowels a Diphthongs, Oral-Motor Movement, Verbal Sequencing, Articulation, Meteorically Complex Words, Transpositions, and Prosody. Each subtest yielded a raw score, which was weighted and summed with the others to form an overall score, which was then co pared to a cutoff score.
Children scoring at or above the cutoff score were appropriate candidates for further speech, language, and possible medical assessment for developmental apraxia of speech. My experience from regular use of the STDAS led to several insights that affect its revision as the Screening Test for Developmental Apraxia of Speech-Second Edition (STDAS-2). First, long-term use has demonstrated that information from four of the original subtests is as effective as using all eight subtest! To identifying children with developmental apraxia speech. One of the four subtests, Expressive language Discrepancy, is a required prescreening task because a demonstrated difference in expressive and receptive language remains the best indicator to further testing for developmental apraxia of speech.
