Social Communication Trajectories in 801 Infants and Toddlers

801 infants and toddlers were assessed using the Communication and Symbolic Behavior Scales (CSBS) at 12, 15, 18, and 24 months of age. The dataset likely contains longitudinal scores for social, speech, and symbolic composites, modeled to identify distinct developmental trajectories. It was created by Laura A. Edwards and published on figshare under a CC-BY-4.0 license.

Use Cases

• Identifying distinct developmental trajectories based on social, speech, and symbolic composite scores.
• Analyzing associations between early trajectory class membership and later diagnostic outcomes.
• Examining links between social communication trajectories and 24-month language outcomes.
• Investigating heterogeneity in development across social communication skills and within diagnostic categories.

Strengths

• 801 participant observations provide a substantial sample size.
• Data collection spans four time points (12, 15, 18, and 24 months) for longitudinal analysis.
• Standardized assessment tool (CSBS) used for measurement.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is 623.9 KB, indicating a limited scope of data.
