The NBWHP's self-help groups often would range from three to ten women and met every week for two to three hours. These groups often met in women's homes, community centers, or churches and while some groups formed around similar lived experiences of health issues many were formed from women's existing social networks. Self-help groups were led by codevelopers who three times a year received training from the NBWHP. In 1989 the NBWHP estimated that 2,000 women were involved in self-help groups. In 2000, the NBWHP stated that over 30,000 women participated in self-help groups since the NBWHP was founded.
