Specialist-Mediated Play Therapy Outcomes for Toddlers with Language Delay

Yingjie Zhan published a dataset from a single-center observational pilot study on figshare. The study examined 180 toddlers aged 18–36 months with mild language developmental delay, comparing outcomes from three intervention strategies over 12 months. Language developmental quotient scores were assessed at baseline, 6 months, and 12 months.

Use Cases

• Compare longitudinal language score trajectories based on three intervention types described in the study.
• Analyze the association between specialist-mediated play therapy and language category improvement rates.
• Investigate group-by-time interaction effects on developmental outcomes in a non-randomized design.

Strengths

• Includes data for 180 children across three intervention groups.
• Provides longitudinal measurements at three time points over a 12-month period.
• Uses a standardized diagnostic scale (Gesell Developmental Diagnosis Scale).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The non-randomized observational design limits causal inference, as noted in the conclusion.
