PHONOLOGY AND ARTICULATION
BBTOP-2: Bankson-Bernthal Test of Phonology– Second Edition Nicholas W. Bankson • John E. Bernthal AGES: 3-0 through 9-11 TESTING TIME: 15 to 20 minutes ADMINISTRATION: Individual The Bankson-Bernthal Test of Phonology–Second Edition (BBTOP-2) is an individually administered assessment of young children’s speech-sound development. The test is actually three assessments in one: a whole-word accuracy analysis, an inventory of consonant articulation, and an assessment of common phonological error patterns. Colorful illustrations are used to elicit the child’s pronunciation of 80 common stimulus words. To administer the BBTOP-2, the examiner simply points to each illustration and has the child name it. The stimulus words are conveniently preprinted in the International Phonetic Alphabet (IPA) on the record form. The examiner uses IPA to transcribe any words the child misarticulates. After the child has named all 80 stimu- lus words and test administration has concluded, the examiner uses the transcription of the misarticulated words to complete the Consonant Articulation Inventory, which assesses articulation of both initial and final consonants. Finally, the examiner can complete the Error Pattern Assessment of common phonological error patterns that may be evident in the misarticulated words. The test’s results can be used to (a) iden- tify children who have speech-sound disorders, (b) plan interventions, and (c) represent speech-sound development and speech-sound disorders in research studies. FEATURES • An all-new standardization sample was collected. • The recording and scoring materials were made more user-friendly. • A comprehensive stimulability testing section was added to provide additional infor- mation relative to treatment targets. • A set of item bias studies indicates that the BBTOP-2 possesses little or no bias in regard to gender, race, and ethnicity.
• New floor, ceiling, and item gradient studies were conducted for the test’s three indexes. • A study of the test’s diagnostic accuracy was conducted. Diagnostic accuracy analy- ses are considered the most rigorous techniques for establishing a test’s validity. These analyses involve the computation of sensitivity and specificity indexes and receiver operating characteristic/area under the curve (ROC/AUC) statistics. TECHNICAL AND STATISTICAL CHARACTERISTICS OF THE BBTOP-2 The BBTOP-2 was normed on a sample of 770 children from 33 states and 248 zip codes. The test yields normed scores for the Word Inventory, Consonant Articulation Inventory, and Error Pattern Analysis. The Examiner’s Manual includes a comprehen- sive discussion of the test’s theoretical and research-based foundation, item devel- opment, standardization, administration and scoring procedures, norms tables, and guidelines for using and interpreting the test’s results. The Word Inventory internal consistency reliability coefficient is .97, and the retest reliability coefficients for the Consonant Articulation Inventory and the Error Pattern Assessment are .87 and .88, respectively. Validity studies demonstrate the test’s ability to differentiate children with speech-sound disorders from those without. Specifically, a Word Inventory cutoff score of 90 resulted in a sensitivity of .81, a specificity of .82, and a ROC/AUC of .89 in differentiating children with speech-sound disorders from children without.
