Research has shown that mobile phone contraceptive behavioral interventions can increase knowledge and use of contraception, but other studies have failed to demonstrate a beneficial effect. The objective of this trial was to estimate the effect of a contraceptive behavioral intervention delivered by mobile phone text message on young Palestinian women's attitudes towards effective contraception.
We conducted a randomized controlled trial among women aged 18-24 years living in the West Bank, who were not using an effective method of contraception. The intervention group received zero to three messages per day (113 messages for female-not married and 120 messages for female-married) for 120 days. The control group received 16 messages over 120 days about trial participation. The primary outcome was acceptability of at least one method of effective contraception at 4 months. Secondary outcomes were use of effective contraception at 4 months and any use during the study, acceptability of individual methods, service uptake, unintended pregnancy and abortion. Process outcomes included knowledge, perceived norms, personal agency and intention. All outcomes were self-reported. We analyzed the outcomes using logistic and linear regression.
A total of 578 participants were enrolled and 464 (80%) completed follow up at 4 months. Intervention group participants were more likely to find at least one method of effective contraception acceptable (31% in the intervention group versus 17% in the control group, adjusted OR 2.34, 95% CI 1.48-3.68, p < 0.001). They had a higher mean knowledge score, were more likely to find the intrauterine device, injection, implant and patch acceptable, to agree that their friends would use an effective method and to intend to use an effective method, compared to participants in the control group. While in the direction of intervention benefit, there were no differences between the groups in the use of effective contraception at 4 months and any use during the study, pill acceptability, service uptake, unintended pregnancy and induced abortion.
The intervention can improve attitudes, knowledge-perceived norms and intention to use effective contraception among young women in Palestine. Research is needed to evaluate the efficacy of the intervention for contraceptive behavioral outcomes in Palestine.

研究表明，手机避孕行为干预可以增加对避孕的知识和使用，但其他研究未能证明其有益效果。本试验的目的是估计通过手机短信对年轻巴勒斯坦妇女进行避孕行为干预对其有效避孕态度的影响。
我们在 18-24 岁的居住在西岸的未使用有效避孕方法的妇女中进行了一项随机对照试验。干预组每天接受零到三条短信（未婚女性 113 条，已婚女性 120 条），共 120 天。对照组在 120 天内收到了 16 条关于试验参与的短信。主要结局是在 4 个月时接受至少一种有效避孕方法的可接受性。次要结局是在 4 个月时使用有效避孕方法和研究期间的任何使用、接受个别方法、服务利用率、意外怀孕和堕胎。过程结局包括知识、感知规范、个人代理和意图。所有结果均为自我报告。我们使用逻辑和线性回归分析了结果。
共纳入 578 名参与者，其中 464 名（80%）在 4 个月时完成了随访。干预组参与者更有可能发现至少有一种有效的避孕方法是可接受的（干预组 31%，对照组 17%，调整后的 OR 2.34，95%CI 1.48-3.68，p<0.001）。与对照组相比，他们的平均知识得分更高，更有可能发现宫内节育器、注射、植入物和贴片是可接受的，更同意他们的朋友会使用有效的方法，并打算使用有效的方法。虽然干预组有获益的趋势，但两组在 4 个月时有效避孕的使用和研究期间的任何使用、避孕药的可接受性、服务利用率、意外怀孕和人工流产方面均无差异。
该干预措施可以改善巴勒斯坦年轻女性对有效避孕的态度、知识-感知规范和使用意图。需要研究评估该干预措施对巴勒斯坦避孕行为结果的疗效。
