目的分析总结公共卫生类期刊涉及调查研究文献中抽样设计的常见问题及特点,为建立公共卫生类期刊文献中抽样设计的规范体系奠定基础。方法设计公共卫生类期刊文献调查研究抽样设计常见问题调查表,随机抽取10种公共卫生类核心及以上级别期刊,查阅其2014年发表的所有文献,采用定性研究方法总结分析其中常见抽样方法的问题类型与特点。结果公共卫生类期刊文献中抽样设计的常见问题主要表现为:(1)分层抽样:未对“层”定义;未说明分层标准;未说明所分层数及每层单位数具体大小;未提供上述各点判定依据;(2)整群抽样:未对“群”定义;未说明分群标准;未说明所分群数及每群单位数具体大小;未提供上述各点判定依据;(3)系统抽样问题:未明确抽样间隔;未明确欲抽样样本组数;(4)多阶段抽样问题:各阶段表达过于简单;单阶段抽样表述不完整;多阶段抽样命名问题。结论选定公共卫生类期刊文献中,抽样设计问题表现较为集中、特点明显,目前文献中抽样设计的表述尚不规范,有待进一步研究以规范化。
OBJECTIVE: To analyze and summarize the common problems and characteristics of sampling design in public health journals, and to lay the foundation for the establishment of a standardized system of sampling design in public health journals. Methods A questionnaire of common problems in sampling and design of public health periodical literature was designed and randomly selected from 10 public health core and above journals, all the documents published in 2014 were reviewed, and the problems of common sampling methods were summarized and analyzed by qualitative research methods Type and characteristics. Results The common problems of sampling design in public health periodicals literature mainly showed as follows: (1) Stratified sampling: no definition of “layer ”; no standard of stratification; no specification of stratified number and number of units per floor Size; not provide the basis for determining the above points; (2) cluster sampling: no definition of “group ”; did not specify the grouping criteria; did not specify the number of groups and the specific size of each group of units; Basis; (3) systematic sampling problem: no clear sampling interval; no clear desire to sample the number of samples; (4) multi-stage sampling problem: each stage expression is too simple; single-stage sampling is incomplete; Conclusion In the selected public health periodicals literature, the sampling design problems are more concentrated and the characteristics are obvious. At present, the description of sampling design in the literature is not standardized and needs further research to be standardized.
