Finite storage capacities of household pit latrines make safely managing fecal sludge a recurring challenge for 2.7 billion people globally. Frequently without guidance from standards or regulation, rural latrine owners choose how to manage their own fecal sludge. However, their intentions – what behavioral science says are the best predictors of future behaviors – when pits fill are poorly understood, inhibiting the development of safe fecal sludge management (FSM) solutions and deteriorating public and environmental health. Using survey data commonly measured by development practitioners, we analyze response frequencies and their associations with contextual factors, such as location, month that the survey was administered, and poverty level. We also use binomial logistic regression to determine if contextual factors can be used to predict the intentions of rural Cambodian latrine owners when pits fill. We found that four in ten rural latrine owners intend to manage their fecal sludge unsafely (41%), and one in six did not have a plan (16%). Desirable FSM intentions increased markedly after rice harvest and varied markedly across provinces. Many predictors of desirable FSM intentions, such as location and satisfaction with the household's latrine, were also identified. Associations between FSM intentions and contextual factors can be used to help predict FSM behaviors and improve FSM service delivery, behavior change campaigns, and product design. However, future work should seek to characterize the complete decision-making processes of rural latrine owners when pits fill.

家庭便池的有限存储能力使安全管理粪便污泥成为全球27亿人口经常遇到的挑战。农村厕所所有者常常没有标准或法规的指导，而是选择如何管理自己的粪便污泥。但是，他们的意图-行为科学所说的是未来行为的最佳预测因子-当坑坑填满时，人们对此知之甚少，从而阻碍了安全粪便污泥管理（FSM）解决方案的开发，并恶化了公共和环境健康。使用开发人员通常测量的调查数据，我们分析了响应频率及其与上下文因素的关联，例如位置，管理调查的月份以及贫困程度。我们还使用二项式Logistic回归来确定是否可以使用上下文因素来预测坑填满时柬埔寨农村厕所的所有者的意图。我们发现，十分之四的农村厕所所有者打算不安全地管理粪便污泥（41％），六分之一的人没有计划（16％）。水稻收获后，理想的FSM意图明显增加，各省之间差异明显。还确定了许多理想的FSM意图预测因素，例如位置和对家庭厕所的满意度。FSM意图与上下文因素之间的关联可用于帮助预测FSM行为并改善FSM服务交付，行为更改活动和产品设计。但是，将来的工作应设法在坑坑填满时表征农村厕所所有者的完整决策过程。
