Centre for Time Use Research UK Time Use Survey 6-Wave Sequence across the COVID-19 Pandemic, 2016-2021

<div>In 2016 the Centre for Time Use Research developed an online Click and Drag Diary Instrument (CaDDI), collecting population-representative (quota sample) time use diary data from Dynata’s large international market research panel across 9 countries. We fielded the same instrument using the UK panel across the COVID-19 pandemic: in May-June 2020 during the first lockdown; in late August 2020 following the relaxation of social restrictions; in November 2020 during the second lockdown; in January 2021 during the third lockdown; and in August/September 2021 after the lifting of restrictions.</div><div><br></div><div>Each survey wave collected between 1-3 time use diaries per respondent, recording activities, location, co-presence, device use, and enjoyment across continuous 10-minute episodes throughout the diary day.  The accompanying individual screening questionnaire included information on the standard socio-demographic variables, and a diary day questionnaire containing additional health and diary day related questions was added during wave 2. Overall, 6896 diaries were collected across the 6 waves, allowing analysis of behavioural change between a baseline (in 2016), three national lockdowns, and two intervening periods of the relaxation of social restrictions.</div><div><br></div><div>The deposited data forms part of wider CTUR projects of ESRC-funded time use research - New Frontiers for Time Use Research, and Time Use Research for National Statistics. Information on time spent in the various activities of daily life provides a comprehensive and exhaustive basis for summarising the activities of a society, yet people in general do not know with any accuracy how much time they devote to their daily activities. For this reason, rather than asking a set of survey questions, such as "how much time did you spend last week in X activity", the time use diary instead asks people to record, in sequence, all their activities through the 24-hour day, with their start and end times. Further information both on these projects and the COVID-19 sequence data collection can be found on the <a href="http://www.timeuse.org">CTUR</a> website.</div><div><br></div><div><span style="font-weight: bold;">Latest edition information</span></div><div>For the fourth edition (May 2022), the data and documentation files were replaced with updated versions. Amendments include the replacement of questionnaires with final versions; changes to variable ordering in the questionnaires, dataset and codebook; and updated information on the GHQ questions. See the Summary of Changes document for further details.</div><div><br></div>

2016年，时间使用研究中心（Centre for Time Use Research）开发了一款在线点击拖拽日记工具（Click and Drag Diary Instrument, CaDDI），从覆盖9个国家的戴纳塔（Dynata）大型国际市场调研固定样本组中，采集具有人口代表性（配额抽样）的时间使用日记数据。本研究在新冠疫情期间，依托英国调研固定样本组沿用同款工具开展多轮调查：分别为2020年5-6月首次全国封控期间、2020年8月下旬社交限制放宽后、2020年11月第二次封控期间、2021年1月第三次封控期间，以及2021年8-9月限制解除后。

每轮调查为每位受访者采集1至3份时间使用日记，记录受访者在日记覆盖的整日中每段连续10分钟时段内的活动内容、所处地点、陪同人员、设备使用情况及主观愉悦感受。配套的个人筛选问卷包含标准社会人口统计学变量信息，且在第2轮调查中新增了一份日记日问卷，涵盖额外的健康及日记日相关问题。六轮调查累计共采集6896份日记数据，可用于分析基准期（2016年）、三次全国性封控以及两次社交限制放宽过渡期之间的行为变化。

本存档数据隶属于英国经济和社会研究理事会（Economic and Social Research Council, ESRC）资助的时间使用研究系列项目，即“时间使用研究新前沿”与“面向国家统计的时间使用研究”。对日常生活各类活动耗时的统计数据，可为总结一个社会的整体活动提供全面且详尽的依据，但普通民众往往无法准确知晓自己在日常活动上投入的时间总量。正因如此，时间使用日记并未采用诸如“上周你在X活动上花费了多少时间”这类常规问卷提问方式，而是要求受访者按时间顺序记录24小时内的所有活动，并标注每项活动的起止时间。如需了解上述项目及本次新冠疫情序列数据采集的更多细节，可访问<a href="http://www.timeuse.org">CTUR</a>官网。

**最新版本说明**

针对2022年5月发布的第4版数据集，已将数据与文档文件更新为最新版本。修订内容包括：将问卷替换为最终定稿版本；调整问卷、数据集与编码本中的变量排序；更新一般健康问卷（General Health Questionnaire, GHQ）相关信息。如需了解更多细节，请查阅《变更摘要》文档。
