Summary
Efficient language sample analysis for deaf and hard of hearing (DHH) preschoolers is possible with shorter samples. Even 3-minute language samples provide reliable data, challenging the need for extended warm-up periods.
Area of Science:
- Speech and Language Pathology
- Developmental Psychology
- Pediatric Audiology
Background:
- Language sample analysis (LSA) is crucial for assessing language development in young children.
- Time constraints often limit the feasibility of comprehensive LSA.
- Reliable and efficient sampling methods are needed for clinical and research applications, especially for young deaf and hard of hearing (DHH) children.
Purpose of the Study:
- To identify efficient and reliable language sampling procedures for young DHH children.
- To examine the influence of language sample length, timing, and elicitation context on the reliability of common language measures.
Main Methods:
- 21 DHH children (3-5 years old) provided 10-minute play and conversation samples.
- Samples were analyzed for MLU-W, MLU-M, words per minute, and different words per minute.
- Reliability was assessed by comparing shorter segments (1-7 min) to full samples using Cronbach's alpha.
Main Results:
- Language samples of 3, 5, and 7 minutes demonstrated strong reliability across all analyzed measures.
- Sample timing (beginning vs. later) and elicitation context (play vs. conversation) had minimal impact on reliability when sample length was adequate.
Conclusions:
- A 3-minute language sample is sufficient for reliable and time-efficient LSA in DHH preschoolers.
- Reliable language data can be obtained from the beginning of the elicitation task, potentially eliminating the need for a warm-up period.
