Ethics approval and consent to participate
: The original prospective study received ethics approval by each site’s Institutional Review Board (IRB). Enrolled participants provided written informed consent and were offered small incentives in the form of gift cards. The IRBs also provided ethics approval for the secondary analyses presented here that examined descriptive information of women who could not be reached or refused recruitment. IRBs approved compiling de-identified data on non-consented health plan members in accordance with health plan membership rules; local sites then presented in frequency tables with large cell sizes.The Kaiser Foundation Research Institute Institutional Review Board, the Kaiser Permanente Northwest Institutional Review Board, and the Abt Associates Insitutional Review Board approved study instruments, procedures, and written consent documents. Verbal consent was approved for initial telephone contact and orientation; written consent was completed before finishing enrollment. Only women who provided written consent are included as “enrolled participants.” All institutional review boards approved the use of frequency tables to describe the characteristics of participants refused to participate in the study or who were never reached.
