Screening children from birth through age 5 is critical to early identification of challenges and referral to intervention to support optimal development. Screening of American Indian and Alaska Native (AIAN) children lags behind that of other children, partly due to the lack of screening tools validated for this population. This study tested the feasibility of an online data collection strategy for use in a future study of the validity of existing screening instruments for AIAN children. Parents of AIAN children in four communities were recruited to complete screeners, provide demographic information, and provide feedback on experiences with online data collection. Participants were given the option of receiving screening results from the local early childhood program through which they were recruited. 240 participants began the process, 183 were enrolled in a partner program and reported a birthdate for at least one AIAN child, 157 had an age-eligible child, 81 began the consent process, 62 consented, and 39 fully completed data collection. Most participants were female and AIAN, the majority reported that online data collection was easy. Collecting screener validation data on a large sample of AIAN children may be able to utilize online data collection tools, with in-person support to facilitate participation. (author abstract)
