These data are from Wave 2 data collection for the PROMIS Early Childhood (EC) Parent Report measure development and validation study (see Cella, Blackwell, & Wakschlag, 2022 for overview). Wave 2 data were collected via Ipsos using their probability-based nationally representative online survey panel. The overall aim of Wave 2 data collection was to finalize item calibration and establish norms. Data were collected from n=1,057 parents of children ages 1-5 years. For measures consisting of more than 8 items, an 8-item short form was administered. All parents completed all items. See Lai et al., 2022 for an overview of the sample and psychometric methods.
