We assessed three influences on behavioral intention to collect data derived from the TPB: (a) attitude toward collecting data, (b) social norms for collecting data, and (c) perceived behavioral control for collecting data.

Early literacy individual growth and development indicators (EL-IGDIs): growth trajectories using a large, internet-based sample.

Early literacy individual growth and development indicators (EL-IGDIs) assess preschoolers' expressive vocabulary development and phonological awareness. This study investigated longitudinal change in EL-IGDIs using a large (N=7355), internet-based sample of 36- to 60-month-old United States preschoolers without identified risks for later achievement delays. There were three major findings.
