BBTOP Bankson-Bernthal Test of Phonology
Description • Developed in 1989 • Authors: • Nicholas W. Bankson • John E. Bernthal • Designed to serve as a quick and easy method for assessment of phonology in preschool and school-age children • Organized into three sections: • Consonant Inventory • Phonological Process Inventory • Word Inventory
Assessment Goals • To assess the number of words produced without any consonant misarticulations • To assess the number of sounds (consonants and consonant clusters) in error. • To assess the number of errors reflecting one or more of the 10 most frequently occurring phonological processes.
Age Population • Designed primarily for preschool and early elementary school children • up to grade level 3 • May be given to older children with severe phonologic/articulation problems • Screening version QSP may be used for a more brief assessment when needed • Quick screen of Phonology (QSP) • Based on 28 of the original 80 test items.
Test Materials • Picture book: • 80 simple, colorful pictures for target ages • Record form: • Organized into sections for easy recording • Examiner’s Manual • Provides source for norm tables for scoring
Consonant Inventory • Includes most English consonants in the initial and final positions • Assesses vocalic ‘er’ (stressed and unstressed) • Selected consonants clusters
Phonological Process Inventory • Provides a system for reviewing child’s phonologic production for the presence of 10 most frequently occurring phonological processes: • Assimilation • Fronting • Final consonant deletion • Weak syllable deletion • Stopping • Gliding • Cluster simplification • Depalatilization • Deaffrication • Vocalization
Word Inventory • Provides a short, reliable measure of overall phonological performance
Test Administration • Administration time: Approximately 10-15 minutes. • Begin with casual conversation to ease child into comfort zone. • Instruct child to name or describe each picture that you show them from the picture book. • Clinician prompts are provided in Appendix F of the examiner’s manual.
Recording Responses • Mark 1 in the box on response form for item in the column under “Word Correct” if response is articulated correctly. • Mark incorrect articulations with a 0 and then phonetically transcribe the response. • Responses other than the target word should be followed with a clinician prompt (Appendix F), then treated as correct/incorrect. Mark Modeled on the record form.
Scoring Word Inventory • Calculate chronological age • Sum all words without misarticulations (raw score) and put in appropriate box on the record form • Refer to Appendix B to locate percentile rank and standard score based on the raw score.
Scoring Consonant Inventory • Turn to page 3 of the record form • Locate each consonant in it’s specified row • Mark only those consonants in error by circling I (initial) or F (final) • For each consonant, count the number of times I and F were circled in its column • OR you may use the developmental scale scoring method: • ranges from 0-4 • 0= No difficulty with sound • 4= Strong evidence of difficulty with sound
Scoring Phonologic Process Inventory • Form has 10 columns, representing the 10 phonological processes tested • Each word on the test is listed in each column • Examples of each phonological process are provided in each column • Circle the word in each column that each specific phonological process occurs • Total the number of times each process is identified in each column • Add totals to get raw score • Refer to Appendix D in examiner’s manual to convert to %tile score and standard score.
Test Standardization • The BBTOP is standardized based on a sample size of 1070 subjects • Ages 3-9 years • 61 sites across the United States • Standardization based on quantifying a child’s phonological performance
Test Norms • Examiner’s manual provides norm tables for 3 sections of the test • Based on a Mean of 100 and Standard Deviation of 15 • Norms based on 3 month age intervals from 3-0 to 6-11 and 6 month intervals from 7-0 to 9-11
Pros: Quick and Easy Used as a formal test or as a screening device Colorful pictures Well-organized record form Cons: Can be confusing to new examiners Older test (1989) Pros and Cons
