Abstract
Data from three NIH Environmental influences on Child Health Outcomes (ECHO) Program cohorts that collected the HOME-Infant-Toddler (HOME-IT age 0–3 years) version were used to examine the reliability of a brief scale of caregiver support and cognitive stimulation. Participants with HOME-IT data (N = 2518) were included in this analysis. Mean child age at HOME-IT assessment was 1.51 years, 48% of children were female, and 43% of children identified as Black. A four-stage analysis plan was used to evaluate item response theory assumptions, item response theory model fit, monotonicity, scalability, item fit, and differential item functioning. Results indicate the feasibility of developing a reliable 10-item scale (reliability >0.7) with particularly high precision for children with lower levels of cognitive stimulation.
