Parent input and language outcomes in CIs (Luo et al., 2026)

A longitudinal study dataset from 25 Mandarin-speaking children who received cochlear implants before 30 months of age. The data includes parent lexical diversity (NDW) and grammatical complexity (MLU) measures at 1 and 2 years post-implant, correlated with children's standardized language test scores at 3 years post-implant. The dataset was published by Luo et al. in 2026 and is hosted on figshare.

Use Cases

• Analyzing the correlation between parent lexical diversity and child language outcomes based on NDW measures.
• Modeling the relative importance of parent grammatical complexity over time based on MLU measures.
• Studying longitudinal language development patterns in children with cochlear implants based on data collected at three time points.
• Investigating differences in predictors for receptive versus expressive language outcomes based on the study's regression results.

Strengths

• Data is longitudinal, capturing parent and child language measures at three specific time points (1, 2, and 3 years post-CI activation).
• Includes standardized language test scores for child outcomes, providing a validated measure.
• Dataset is associated with a peer-reviewed publication (Luo et al., 2026) in the Journal of Speech, Language, and Hearing Research.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The sample size is 25 participants, which is a small cohort.

Collection Method

Language samples were collected from 30-minute parent-child free play sessions. Parent NDW and MLU were computed from these samples, and child language was evaluated using a standardized test.

Time Range

Data collection occurred at 1, 2, and 3 years after cochlear implant activation.
