The study aimed to develop and validate messages for a mobile phone text-based intervention to enhance human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) risk reduction among long-distance truckers (LDTs) in Kenya.
Initially, key facts and updates on HIV/AIDS risk reduction were extracted from existing guidelines and packaged into short messages targeted for LDTs. Subsequently, a panel of interdisciplinary experts was purposively sampled and invited through individual emails to participate in the e-Delphi exercise. The study involved three phases: formative research, intervention development, and content validation. Two rounds of the e-Delphi exercise were conducted. A consensus threshold of above 75% was adopted. A Fleiss' kappa () statistic was computed to assess the interrater reliability levels in each round of the e-Delphi exercise.
Most experts were of Kenyan citizenship, 21 (88%), except for one Ugandan and two South Africans. A total of 56 items were rated by 24 experts in round one. Out of the 56 items rated in round one, 50 achieved a consensus above 75%. Based on feedback from specific experts in round one, six items were amended, and an extra one was formulated. In round two, seven items were rated. The seven items achieved a consensus level of 98.21%, meaning a third round was unnecessary.
Given the multi-dimensional inputs from the interdisciplinary panel of experts, the text-based intervention is considered a valid tool for promoting HIV/AIDS risk reduction among LDTs. Considering the substantive approval of the intervention from the panel of experts, a short message service-based digital delivery platform will be used in the implementation phase. We recommend regular updates of the intervention, as the evidence is expected to grow and evolve further.
本研究旨在开发并验证用于基于手机短信的干预措施的信息，以增强肯尼亚长途卡车司机降低人类免疫缺陷病毒/获得性免疫缺陷综合征（HIV/AIDS）风险的意识。
最初，从现有指南中提取了关于降低HIV/AIDS风险的关键事实和最新信息，并将其打包成针对长途卡车司机的短信。随后，有目的地抽取了一个跨学科专家小组，并通过个人电子邮件邀请他们参与电子德尔菲法练习。该研究包括三个阶段：形成性研究、干预措施开发和内容验证。进行了两轮电子德尔菲法练习。采用了75%以上的共识阈值。计算了Fleiss' kappa（κ）统计量，以评估每轮电子德尔菲法练习中的评分者间信度水平。
除一名乌干达人和两名南非人外，大多数专家为肯尼亚公民，共21人（88%）。第一轮有24名专家对56项内容进行了评分。在第一轮评分的56项内容中，有50项达成了75%以上的共识。根据第一轮中特定专家的反馈，对6项内容进行了修改，并新增了1项内容。第二轮对7项内容进行了评分。这7项内容的共识水平达到了98.21%，这意味着无需进行第三轮评分。
鉴于跨学科专家小组提供的多维度意见，基于短信的干预措施被认为是促进长途卡车司机降低HIV/AIDS风险的有效工具。考虑到专家小组对该干预措施的实质性认可，在实施阶段将使用基于短信服务的数字交付平台。我们建议定期更新该干预措施，因为预计相关证据会不断增加和演变。
