Diagnosing DLD Using Vietnamese Repetition Tasks<\/h2>\n\n\n\n

Diagnosing developmental language disorder (DLD) in children can be a challenge, and sentence repetition and nonword repetition are tools that can aid identification. While these tools have been well-researched in English, what about its accuracy and reliability in Vietnamese?<\/p>\n\n\n\n

This study<\/a> found that Vietnamese sentence repetition and nonword repetition tasks<\/strong> can be useful for identifying DLD in monolingual Vietnamese children aged 5<\/strong>. More specifically, the tools can accurately determine the likelihood that a child will have DLD based on the score they receive on the assessment.<\/p>\n\n\n\n

Sentence repetition tasks<\/strong> measure grammatical knowledge using grammatical structures that are known to be difficult, such as passive structures and relative clauses. On the other hand, nonword repetition tasks<\/strong> assess speech sounds in short-term memory with nonwords and evaluate the repeated consonants, vowels, and tones in the syllables.<\/p>\n\n\n\n

Sentence Repetition Scoring<\/strong><\/h2>\n\n\n\n

Following the task\u2019s error scoring system, a monolingual Vietnamese child who scores below 89% is at<\/strong> approximately 3x more risk for DLD<\/strong>. This means that a child who earns at least 75 out 84 points can be considered typically developing (i.e., minimal or no risk for DLD) while a child who scores 74 or fewer points is at risk. <\/p>\n\n\n\n

Nonword Repetition Scoring<\/strong><\/h2>\n\n\n\n

Following the task\u2019s syllable scoring system, a monolingual Vietnamese child who scores below 56% is at approximately 4x more risk for DLD<\/strong>. This means that a child should accurately repeat at least 28 out of the 50 syllables to be considered typically developing. Children who accurately repeat 27 or fewer syllables demonstrates risk for DLD.<\/p>\n\n\n\n

Children who are at risk for DLD<\/strong> according to one or both tasks should receive additional testing<\/strong> to either confirm or rule out the possibility of DLD in monolingual Vietnamese children. <\/p>\n\n\n\n

Next steps<\/strong><\/h2>\n\n\n\n

The development of these tasks is a significant advancement for accurately diagnosing developmental language disorder in monolingual Vietnamese-speaking children using the cutoff scores discussed above. These cutoff scores should not be applied to bilingual children<\/strong> who speak Vietnamese as one of their languages. <\/p>\n\n\n\n

The accuracy and cutoff scores for bilingual Vietnamese-English children in a wider age range is currently being determined. In the meantime, these tasks are better suited for progress monitoring and use with local norms among bilingual children who speak Vietnamese.<\/p>\n\n\n\n

For more information<\/strong><\/h2>\n\n\n\n

Access to Vietnamese Sentence Repetition<\/a> and Vietnamese Nonword Repetition<\/a> task materials, scoring instructions, and training videos are available at VietSLP<\/a>. Registration is required, and it will provide access to many additional evidence-based assessment tools and resources. Registration and access are free of charge.<\/p>\n\n\n\n
