Danish Election Studies, Continuity File 1971-1981

The survey is a merged version of the recurring questions in a number of election studies. The election studies which form the basis of this survey are seven studies which were carried out in the period 1971-1981. The first two studies are found in DDA-0007: 'Danish Pre- and Post-Election Study 1971', which is a two-wave panel study concerning the general election on 21 September, 1971. The first wave dates from August 1971, before the writs of the election were issued. The second wave dates from October 1971. A subsample of the respondents who were interviewed in these two waves was interviewed again after the general election on 4 December, 1973, and the results of these interviews are found in DDA-0008: 'Danish Election Study 1973', which forms the third wave of the above-mentioned panel study. DDA-0016: 'Danish Election Study 1975' was carried out in connection with the general election on 9 January, 1975. Some of the questions in this study are replications of questions in the 1971 and 1973 studies, but the respondents are not the same. The same applies to DDA-0166: 'Danish Election Study 1977', which was carried out in connection with the general election on 15 February, 1977 and to DDA-0287: 'Danish Election Study 1979', which was carried out in October and November 1979. However, as regards DDA-0287 the data were collected in two omnibuses: one of the omnibus surveys was carried out in October 1979, immediately after the general election on 23 October, whereas the other one was carried out in November. DDA-0529: 'Danish Election Study 1981' was carried out in December 1981, immediately after the general election on 8 December (also with a new survey population). #Thus, 'Danish Election Studies, Continuity File 1971-1981' consists of seven part-studies carried out between August 1971 and December 1981; however, as the 'Danish Election Study 1979' consists of two omnibuses, there are actually eight part-studies. By and large, the variables are recurring variables, i.e. they occur in all the studies, but in a few cases variables have been included which do not occur in all the studies. Furthermore, some variables have been transferred from the Pre-Election Study 1971 to the Post-Election Study 1971 as well as to the 'Danish Election Study 1973', or variables have been transferred from the Post-Election Study 1971 to the Pre-Election Study 1971 (a thing which is possible as the respondents are the same). There are four main groups of variables: #The variables in the first group deal with the respondent's social background, including sex, age, education, marital status, occupational status, designation of occupation, branch of economy, size of place of work, number of children under 15, type of household, income, household income, type of residence, place of residence (geographical region and degree of urbanization), class affiliation, trade union membership, and church attendance. In addition, there are variables dealing with the occupation of the head of household, the housewife and the father (or other bread-winner). #The variables in the second group deal with political interest and election campaign questions, including questions concerning the role of newspapers, radio and TV during the election campaign (as well as variables concerning newspaper reading habits in general). In addition, there are variables concerning discussions within the family, with friends and with colleagues in connection with the election campaign in question, as well as variables concerning the extent to which the respondent has received or has given advice as to which party to vote for. #The variables in the third group deal with party affiliation and party preference, including actual vote at the general elections, voting intention at a hypothetical election on the day after the interview, reason(s) for the vote, time of decision, party identification, government preference and father's party preference. #The variables in the fourth group deal with political attitudes, including the respondent's opinion of what are the most important political problems, attitude to NATO, the EC, nuclear power, economic equality, investment control, tax progression, wage freeze, organizational power, government intervention in connection with collective bargaining, public assistance, censorship, indoctrination, the moral development of society, conformity and orthodoxy, opinion of politicians, and political self-confidence

本调查整合了多项选举研究中的周期性调研问题。作为本调查基础的七项研究开展于1971年至1981年期间。前两项研究收录于DDA-0007：《1971年丹麦大选前后追踪研究》（Danish Pre- and Post-Election Study 1971），该研究为针对1971年9月21日大选的两波追踪研究（two-wave panel study）：第一波数据采集于1971年8月，即大选公告发布之前；第二波采集于1971年10月。1973年12月4日大选结束后，针对这两波调查中的受访对象子样本（subsample）进行了第三次回访，其调研结果收录于DDA-0008：《1973年丹麦大选研究》（Danish Election Study 1973），构成上述追踪研究的第三波。
DDA-0016：《1975年丹麦大选研究》（Danish Election Study 1975）针对1975年1月9日的大选开展，其中部分问题为1971年与1973年研究中问题的重复测量，但受访对象并非同一群体。针对1977年2月15日大选开展的DDA-0166：《1977年丹麦大选研究》（Danish Election Study 1977），以及1979年10月至11月开展的DDA-0287：《1979年丹麦大选研究》（Danish Election Study 1979）亦遵循此规律。需注意的是，DDA-0287的数据采集自两项综合调查（omnibus survey）：一项于1979年10月开展，紧邻10月23日大选之后；另一项于11月开展。DDA-0529：《1981年丹麦大选研究》（Danish Election Study 1981）于1981年12月开展，紧邻12月8日大选之后，同样采用了全新的受访群体。
综上，《1971-1981年丹麦大选连续性数据集》（Danish Election Studies, Continuity File 1971-1981）包含7项子研究，采集周期为1971年8月至1981年12月；但由于《1979年丹麦大选研究》包含两项综合调查，实际子研究数量为8项。总体而言，本数据集的变量多为周期性变量（recurring variables），即在所有子研究中均有收录，但少数情况下也纳入了仅在部分子研究中出现的变量。此外，部分变量从1971年大选前研究迁移至1971年大选后研究，以及《1973年丹麦大选研究》；亦有部分变量从1971年大选后研究迁移至1971年大选前研究——由于受访对象群体一致，该操作具备可行性。本数据集包含四大类变量：
第一类变量聚焦受访对象的社会背景，涵盖性别、年龄、受教育程度、婚姻状况、职业身份、职业名称、经济行业、工作单位规模、15岁以下子女数量、家庭类型、个人收入、家庭收入、居住类型、居住地（地理区域与城市化程度）、阶层归属、工会会员身份以及教堂出席情况。此外，还包含户主、家庭主妇与父亲（或其他家庭经济支柱）的职业相关变量。
第二类变量围绕政治兴趣与竞选活动展开，涵盖大选竞选期间报纸、广播与电视的角色（同时包含一般性的读报习惯变量）。此外，还包含受访对象在竞选期间与家人、朋友及同事的政治讨论相关变量，以及受访对象获取或提供政党投票建议的程度相关变量。
第三类变量涉及党派归属与投票偏好，涵盖大选实际投票情况、受访当日假设性选举的投票意向、投票理由、决策时间、党派认同、政府偏好以及父亲的党派偏好。
第四类变量聚焦政治态度，涵盖受访对象对当前最紧迫政治问题的看法、对北约、欧共体、核电、经济平等、投资管制、累进税制、工资冻结、组织权力、政府对集体谈判的干预、公共援助、审查制度、灌输式教育、社会道德发展、从众与正统观念、对政客的看法以及政治自信心等议题的态度。
