Protocol - Non-word Repetition
Protocol Name from Source:This section will be completed when reviewed by an Expert Review Panel.
Description:Non-word Repetition is an interviewer-administered test that is a part of the Comprehensive Test of Phonological Processing (CTOPP). The respondent listens to a series of nonsense words played on an audio CD and repeats them back to interviewer.
Summary of the Non-word Repetition subtest of the Comprehensive Test of Phonological Processing (CTOPP)
The Non-word Repetition test, a subtest of the Comprehensive Test of Phonological Processing, is comprised of items containing varying numbers of nonsense syllables. Accuracy is scored as the number of consonants and vowels repeated correctly. Items are presented with a ceiling. The maximum number of items is 18.
Percentiles, standard scores, and age and grade equivalents are provided with the purchase of the Comprehensive Test of Phonological Processing. Age and grade equivalents show the relative standing of individuals' scores.

Personnel and Training RequiredThe Comprehensive Test of Phonological Processing (CTOPP) can be administered by trained research assistants. Examiners should have formal training in the ethical administration, scoring, and interpretation of clinical assessments. Additionally, investigators are encouraged to have quality control procedures in place to maintain consistency among examiners.
The interviewer will need the Comprehensive Test of Phonological Processing (CTOPP) record booklet, picture book, and test manual.

October 8, 2010
DefinitionThis measure is a test to assess the ability of the respondent to repeat multi-syllable nonsense words.
This measure is used to assess an individual's ability to code and temporarily store information phonologically. This ability is related to verbal memory and language acquisition.
Non-word Repetition was selected because it is a short, widely used, validated protocol that is easy to administer and includes normed data to assist scoring.

Non-word repetition has been identified as a clinical marker of specific language impairment (SLI) in children. See Tager-Flusberg, H., & Cooper, J. (1999). Present and future possibilities for defining a phenotype for specific language impairment. Journal of Speech, Language, and Hearing Research, 42, 1275–1278.
CTOPP scores have yielded borderline significance in a family-based linkage study with probands ascertained as SLI. See Rice, M. L., Smith, S. D., & Gayan, J. (2009). Convergent genetic linkage and associations to language, speech, and reading measures in families of probands with Specific Language Impairment. Journal of Neurodevelopmental Disorders, 1, 264–282.
