A population-based survey that uses a mixed-mode approach, including mail, phone, and web to survey all CNMI mothers who have recently given birth, utilizing a stratified sampling method. A sample is drawn by the Health Vital Statistics Office (HVSO) every 1st of the month, which is then processed through the Statistical Analysis System (SAS) by PRAMS staff. Once the sample is cleaned, it is uploaded into the PRAMS Integrated Data Collection System (PIDS) on the 15th, with each birth record typically being 2 to 3 months old. Data collection occurs over a maximum of 95 days, following a structured schedule for mailing and phone, as detailed in the table below. The web option is introduced at the beginning of the pre-letter, allowing mothers to complete the survey at their convenience. Throughout the period, mothers receive two mailing packets with opportunities to mail back responses or drop them at designated drop boxes. PRAMS staff are trained to conduct telephone interviews using a standardized script, with calls scheduled during regular business hours and by appointment in the evenings and at weekends to maximize participation. Mothers who participate receive a reward as a token of appreciation. All responses are kept completely private and are aggregated to provide insights into the health and well-being of CNMI mothers and babies. The collected data are intended to inform efforts to improve healthcare services and guide programs and policies for women and children in the CNMI.
