Children are highly regarded and treasured as the future of American Indian and Alaska Native (AIAN) communities. Developmental disorders, however, are more frequently undiagnosed and untreated in AIAN children compared to others in the United States. Developmental screening can help communities ensure that their children reach their full potential, but lack of culturally sensitive and valid screening measures complicates screening among AIAN children. This can, in turn, delay access to early intervention and undermine the ability of AIAN communities to support children’s optimal development. This study explored families’ and professionals’ perceptions of screening systems and processes in AIAN communities and to identify gaps and opportunities. 53 interviews and 23 focus groups were conducted with 157 parents and early childcare professionals in four AIAN communities.
