How can PRAMS survey response rates be improved among American Indian mothers? Data from 10 states.

Objectives: To examine the low response rates to the Pregnancy Risk Assessment and Monitoring System (PRAMS) survey for American Indian (AI) mothers by comparing characteristics of AI participants, AI non-participants, non-Hispanic White (NHW) participants, and NHW non-participants.

Methods: We analyzed 2000-2002 data from states whose population was at least 5% AI or Alaska Native (AN) (n = 10). Mothers who returned a questionnaire (regardless of completion) or who spoke by telephone with PRAMS personnel were defined as contacts.
