The Washington State Client Centered Pregnancy Prevention Programs include school-based and community-based programs that focus on providing adolescents with education, support, and information to help them avoid early sexual activity and pregnancy. Three projects, funded by the Washington State Department of Health, were implemented with 391 teen females aged 14 to 17 between 1995 and 1999. Most teens participated in the implementation for 1 to 2 years, and each program consisted of a different implementation. Program #1 was held in a family planning clinic. Program #2 was held in middle and high schools and administered by a family planning provider. Program #3 was administered in schools- and community-based settings by a local health department. The intervention was made up of several components, combining traditional sexuality education with a broader youth development approach. Intervention components include 1) an educational component with regular group meeting to address issues related to sexuality, pregnancy and STD prevention, relationships, self-esteem, decision-making, and life planning; 2) individualized support services, referrals, and counseling that are tailored to meet the needs of each participant and the community they live in; 3) family planning services; and 4) social and recreational activities. An experimental evaluation of the Washington State programs shows a reduced likelihood of sexual activity and increased contraceptive use at Program #2 compared to a control group, and improved sexual and contraceptive intentions, but not behaviors, in Program #1 compared to a control group. No two sites had the same positive impact, and Program #3 showed impact on outcomes.
