This paper tests the structure of the First Years Inventory (FYI 3.1), a measure of social communication (SC) and sensory regulation (SR) and whether the structure varies over age; data collection was done on a community sample of 1,893 children between 8 and 16 months old. Results provided support for eight factors, three SC and five SR. There is evidence that the overall structure holds over the range of ages assessed, with some variability in factor loadings and between-factor correlations.
