逻辑模型（LMs）在项目评估中已经使用了40多年。当前的争论质疑逻辑建模技术将上下文因素纳入逻辑模型的能力。我们分享了在正在进行的现实主义评估中开发逻辑模型的经验，该评估评估了社区卫生工作者方案在多大程度上以及在何种情况下促进尼日利亚获得产妇服务。本文通过以下方式为逻辑建模辩论做出了贡献：i)反思其他学者如何在理论驱动的评估中捕捉LM发展过程中的背景；ii)解释我们如何在逻辑模型开发过程中探索背景，以对尼日利亚CHW项目进行现实评估。为我们的逻辑模型开发提供信息的数据收集方法包括文件审查、与项目利益相关者的电子邮件讨论和电话会议，以及与研究人员的技术研讨会，以澄清项目目标和理清项目要素之间的关系。最重要的发现之一是，逻辑模型开发本身并不是目的，而是确定初步假设的必要步骤，这些假设是关于方案如何产生变化的试探性相关背景、机制和结果（CMO）以及CMO配置。逻辑模型还为编写一本指导核查和巩固基本方案理论的方法论手册提供了信息。
Logic models (LMs) have been used in programme evaluation for over four decades. Current debate questions the ability of logic modelling techniques to incorporate contextual factors into logic models. We share experience of developing a logic model within an ongoing realist evaluation which assesses the extent to which, and under what circumstances a community health workers (CHW) programme promotes access to maternity services in Nigeria. The article contributes to logic modelling debate by: i) reflecting on how other scholars captured context during LM development in theory-driven evaluations; and ii) explaining how we explored context during logic model development for realist evaluation of the CHW programme in Nigeria. Data collection methods that informed our logic model development included documents review, email discussions and teleconferences with programme stakeholders and a technical workshop with researchers to clarify programme goals and untangle relationships among programme elements. One of the most important findings is that, rather than being an end in itself, logic model development is an essential step for identifying initial hypotheses for tentative relevant contexts, mechanisms and outcomes (CMOs) and CMO configurations of how programmes produce change. The logic model also informed development of a methodology handbook that is guiding verification and consolidation of underlying programme theories.
