Danish Omnibus Survey, April 1991

The themes of this omnibus are: #Contact with the public health service system; and knowledge of and experience with self-help groups. # The Danish National Institute of Social Research and Danmarks Statistik have carried out the so-called omnibus surveys regularly from January 1974 till the end of 1991 (from 1993 the Danish National Institute of Social Research has carried out its own omnibus surveys). The omnibus project was established as the Danish National Institute of Social Research, Danmarks Statistik, a number of other government institutions and researchers often experienced a need for examining major or minor problems without initiating independent surveys. The purpose of these surveys is to collect data on a variety of issues in the same interview. This means that the background information may be used in several surveys, thus reducing the costs of the data collection. The omnibus surveys are carried out each year at regular intervals. # A permanent part of the questionnaire in an omnibus survey is the so-called background questions, i.e. a number of questions which map out the respondent's personal and social situation. These background variables are described in the section 'Variables included'. # In addition to the background questions the questionnaire includes questions from external users - questions which form part of the Danish National Institute of Social Research's or Danmarks Statistik's part of the omnibus in question. These questions may deal with a variety of subjects. In principle all types of questions may be included in an omnibus, even if the questions deal with many different subjects, as the editors link the various series of questions. In this way abrupt and strange breaks are avoided, breaks which might distrub the interviewing. Technically it is also possible to ask a number of questions only to specific sub-groups of the sample, e.g. to women in a certain age group. # The data material filed at the DDA comprises the background questions asked jointly by the Danish National Institute and Danmarks Statistik as well as the questions asked by the Danish National Institute of Social Research

本综合抽样调查（omnibus survey）的主题为：
# 与公共卫生服务体系的接触情况；以及自助团体的相关知识与经历。
# 丹麦国家社会研究所（Danish National Institute of Social Research）与丹麦统计局（Danmarks Statistik）自1974年1月至1991年底定期开展此类综合抽样调查；1993年起，丹麦国家社会研究所独立开展自身的综合抽样调查项目。综合调查项目的设立初衷，是由于丹麦国家社会研究所、丹麦统计局、多家其他政府机构及研究人员时常需要针对各类大小问题开展调研，但又不愿启动独立调查项目。此类调查的核心目的为：通过同一场访谈收集多类议题的数据，从而实现背景信息的复用，降低数据采集成本。综合抽样调查每年按固定周期开展。
# 综合调查问卷中的固定组成部分为所谓的“背景问题”，即用于勾勒受访者个人与社会处境的一系列问题。这些背景变量将在“纳入变量”章节中予以详细说明。
# 除背景问题外，调查问卷还包含外部用户提交的问题——即属于本次综合抽样调查中丹麦国家社会研究所或丹麦统计局模块的相关问题。此类问题可涵盖多样的研究主题。原则上，任何类型的问题均可纳入综合抽样调查，即便各问题涉及的主题差异较大，因为问卷编排人员会将不同的问题序列进行衔接，以此避免可能干扰访谈流程的突兀断裂。从技术层面而言，也可仅向调查样本中的特定子群体提问，例如特定年龄段的女性受访者。
# 存档于丹麦数据档案馆（DDA）的数据资料，包含丹麦国家社会研究所与丹麦统计局共同提出的背景问题，以及丹麦国家社会研究所提出的各类调研问题。
