A clinic-based program designed to improve effective contraceptive use and reduce pregnancy rates among teens did not produce the desired effects (Hercog-Baron, Furstenberg, Shea, and Harris, 1986 - Philadelphia evaluation). Targeting first-time visitors to family planning clinics, the program randomly assigned 417 girls aged 12-17 to one of two special service groups or one of two control groups. The special service groups were designed to facilitate the teen's adjustment to the new contraceptives and to encourage consistent and continued use. The "family support" special service group offered each girl short-term (6 weekly sessions) family counseling services in an attempt to promote greater family involvement in the teen's contraceptive decisions and practices. Teens in the "periodic support" group also received 2-6 follow-up phone calls from clinic staff in the 4-6 weeks after the initial clinic visit. These calls aimed to monitor the teen's experience with the contraceptives. The two control groups received only the regular clinic services. A 15-month follow-up evaluation revealed no significant impact on contraceptive practices or pregnancy rates.
