OBJECTIVE: To assess the long-term impact of implementation intention formation in reducing consultations for emergency contraception and pregnancy testing among teenage women.
DESIGN: Teenage women visiting a family planning clinic were randomly assigned to implementation intention versus control conditions.
MAIN OUTCOME MEASURES: Objective measures of consultation outcomes were obtained from clinic records at 2-year follow-up (N = 227).
RESULTS: Rates of consultation for emergency contraception and pregnancy testing in the implementation intentions condition were 19% and 33% lower, respectively, compared to the rates observed in the control condition. Pregnancy rates were 43% lower. Intervention participants who consulted for emergency contraception and pregnancy testing at baseline were more than twice as likely to change to consulting for contraceptive supplies over the follow-up period compared to equivalent control participants (19% vs. 9%).
CONCLUSION: The impact of implementation intention formation on reducing pregnancy risk among teenagers is durable over 2 years. Implementation intentions were successful in changing behavior among precisely those participants who were at greatest risk of becoming pregnant.
