在儿童有多种环境暴露于肠道病原体的地区，通过测量肠道病原体的外部和内部暴露来确定暴露源，并通过问卷调查和观察清单来补充，以捕获导致暴露风险的行为，这一点至关重要。因此，本研究设计了有效和可靠的问卷，以评估行为和环境条件导致暴露于肠道病原体在埃塞俄比亚西北部农村。我们首先对相关文献进行了深入的探讨，了解了研究目标的理论框架，确定了变量，突出了问卷所测量的内容。然后，我们在每个领域中生成的项目，可以有效地解决研究目标，我们细化和组织的项目在一个合适的格式。然后，我们进行了表面效度和内容效度的专家参与的研究主题。在对内容效度研究中生成的预定稿进行预检验后，我们在随机抽取的150个农村家庭中进行了内部一致性信度检验的试点研究。采用内容效度比（CVR）、项目级内容效度指数（I-CVI）、量表级内容效度指数（S-CVI/UA）和修正的Kappa统计量测量项目的内容效度。此外，我们使用了一致性和一致性指数（即，Cronbach's alpha），以评估项目的内部一致性。内容效度检验结果显示，各条目的CVR值为0.95，I-CVI值为0.97，修正Kappa值为0.97，说明各条目均为适宜条目。量表水平的内容效度指数（S-CVI/UA）为0.95，表明各条目的一致性较高。内部一致性信度测试结果表明，预定稿工具的预定稿的Cronbach's alpha为0.85，表明该工具具有较强的信度。因此，问卷的最后版本有8个方面和80个项目。在这项研究中，我们设计了有效和可靠的问卷，以评估行为和环境条件，导致高风险暴露于肠道感染的农村设置。调查表可作为发展中国家农村环境的一种工具，但需根据当地情况作一些修改。然而，这份问卷本身并不能衡量儿童对肠道感染的暴露。它只是对外部和内部风险评估的补充。
In areas where children have multiple environmental exposures to enteric pathogens, identifying the sources of exposure by measuring external and internal exposures to enteric pathogens and complementing by questionnaire and observational checklist to capture behaviors resulting risk of exposure is critical. Accordingly, this study was conducted to design valid and reliable questionnaire to assess behaviors and environmental conditions resulting exposure to enteric pathogens in the rural northwest Ethiopia. We began with a thorough exploration of relevant literature to understand the theoretical framework on the research objectives to identify variables to highlight what the questionnaire is measuring. We then generated items in each domain that can effectively address the study objectives and we refined and organized the items in a suitable format. Then after, we conducted face and content validity by involving experts on the research subject. After pre-testing a pre-final version of the instrument generated in the content validity study, we conducted a pilot study in 150 randomly selected rural households to test the internal consistency reliability. We used content validity ratio (CVR), item-level content validity index (I-CVIs), scale-level content validity index (S-CVI/UA), and modified kappa statistics to measure content validity of items. Moreover, we used agreement and consistency indices (i.e., Cronbach’s alpha) to assess the internal consistency of items. The content validity test result showed that the value of CVR was 0.95, I-CVIs was 0.97, and modified kappa was 0.97 for the whole items, indicating all the items are appropriate. The scale-level content validity index (S-CVI/UA) was 0.95 for the whole items indicating the agreement among judges to each items is higher. The internal consistency reliability test result indicated that Cronbach’s alpha for the pre-final version of the pre-final tool was 0.85, indicating the strong reliability of the tool. The final version of the questionnaire was, therefore, prepared with 8 dimensions and 80 items. In this study, we designed valid and reliable questionnaire to assess behaviors and environmental conditions that result high risk of exposure to enteric infections in rural settings. The questionnaire can be used as a tool in the rural settings of developing countries with some amendments to account local contexts. However, this questionnaire alone does not measure exposure of children to enteric infections. It only complements external and internal exposure assessments.
