This study examined the impact of implementation intention formation in reducing consultations for emergency contraception and pregnancy testing in young women.
Teenage girls (N = 261) visiting a family planning clinic were randomly assigned to implementation intention versus control conditions and completed questionnaires at recruitment.
Objective measures of consultation outcomes were obtained from clinic records at baseline and 9-month follow-up (n = 200).
Forming implementation intentions significantly reduced consultations for emergency contraception and pregnancy testing at follow-up compared with the control group (38% vs. 55%). There were also differences between the groups in consultation outcomes over time. For instance, whereas 31% of implementation intention participants changed from consulting for emergency contraception and pregnancy testing at baseline to consulting for contraceptive supplies only at follow-up, only 16% of control participants did so.
These results suggest that implementation intention formation is a simple yet effective means of promoting pregnancy prevention among teenagers.
本研究旨在探讨实施意图形成对减少年轻女性紧急避孕和妊娠检测咨询的影响。
访问计划生育诊所的少女（N=261）被随机分配到实施意图组和对照组，并在招募时完成了问卷调查。
基线和 9 个月随访时（n=200）从诊所记录中获得客观的咨询结果。
与对照组相比，形成实施意图显著减少了随访时紧急避孕和妊娠检测的咨询（38%比 55%）。两组之间的咨询结果也存在差异。例如，在实施意图组中，有 31%的参与者从基线时的紧急避孕和妊娠检测咨询转变为随访时仅咨询避孕用品，而对照组中只有 16%的参与者这样做。
这些结果表明，实施意图形成是一种简单而有效的促进青少年妊娠预防的方法。
