We conducted an independent evaluation of the "Teens and Toddlers" intervention. Our randomized trial examined effects on self-reported last sex without contraception, >1 episode of sex without contraception in previous 3 months, expectation of teenage parenthood and youth development score, plus secondary outcomes among 449 at-risk girls age 13/14 in England. The intervention involves 18-20 weekly sessions in pre-school nurseries. Response rates were 95% post-intervention and 91% one year later. At follow-up two, there was no evidence of intervention benefits for primary outcomes and a positive impact for our secondary outcome, low self-esteem. At follow-up one, there was no evidence of benefits for our primary outcomes but evidence of benefits for our secondary outcomes: low self-esteem; low sexual health knowledge; and difficulty discussing the contraceptive pill. The intervention should be refined, with a clearer logic model and more emphasis on sex education, and re-evaluated.
我们对“青少年与幼儿”干预措施进行了独立评估。我们的随机试验研究了对自我报告的最后一次无避孕措施性行为、过去 3 个月内无避孕措施的性行为超过 1 次、青少年生育期望和青年发展评分的影响，以及英格兰 449 名高危 13/14 岁女孩的次要结果。该干预措施涉及在学前幼儿园进行 18-20 周的每周课程。干预后和一年后的回复率分别为 95%和 91%。在随访 2 时，没有证据表明干预对主要结果有好处，而我们的次要结果，即低自尊，有积极影响。在随访 1 时，没有证据表明干预对主要结果有好处，但有证据表明干预对我们的次要结果有好处：低自尊、低性健康知识和难以讨论避孕药。该干预措施应加以改进，更明确的逻辑模型和更加强调性教育，并重新评估。
