目的 评价农村沼气建设及其综合利用的卫生效果与健康教育需求调研方案的科学性和可行性,验证问卷和访谈提纲与调查方案目的和要求的一致性,检查问卷及访谈提纲的针对性、通俗性、可操作性和数据库的有效性。方法 调查人员采用现场观察和随机抽样问卷调查的定量方法进行;对村骨干人群采用专题小组讨论的定性研究方法;调查人员进行调查前培训,考核达标后分组参加预试验调查。在卫生效果指标中选择了对调查户沼气池内的沼液沼渣混合物抽样显微镜检查寄生虫卵的方法。结果 通过两轮预试验,验证了调研方案的组织管理体系的有效性;调研问卷在一般情况、卫生状况、KAP等35项问题中,共发现有2 0个问题的2 6项存在着逻辑顺序、内容重复和遗漏项目等方面的问题;正确地修改和完善了调查问卷和访谈提纲;确定了沼液沼渣混合物寄生虫卵镜检样本的抽取方法和家庭环境卫生指标的观察标准,审核了数据库录入和统计分析的方法。结论 预试验的有效实施,为最终全面实施调研方案的确定提供了科学依据
Objective To evaluate the scientific and feasibility of the health effects of biogas construction and its comprehensive utilization in rural areas and the survey plan of health education needs, verify the consistency of the questionnaire and interview outline with the objectives and requirements of the investigation plan, examine the pertinence of the questionnaire and the outline of the interview, Sexuality, maneuverability and the effectiveness of the database. Methods The investigators used on-site observation and random sampling questionnaires to carry out quantitative methods; the village key population using thematic group to discuss the qualitative research methods; investigators to conduct pre-investigation training, assessment standards after the group to participate in pre-test investigation. The hygienic performance indicators were selected for the investigation of biogas digesters in the biogas slurry mixture sampled microscopic examination of parasite eggs. Results Through two rounds of preliminary tests, the validity of the organization and management system of the research program was verified. Among the 35 items in the general situation, health status and KAP, 26 were found to have a logic order of 20 Content duplication and omission items; correctly revised and perfected the questionnaire and interview outline; determined the extraction method of the egg sample of parasitoid biogas residue mixture and the observation standard of household environmental health indicators, Database entry and statistical analysis of the method. Conclusion The effective implementation of the pre-test provides a scientific basis for the final implementation of the survey plan
