This means a small number of individuals may be miscategorised as non-adherent. While we have made improvements to reduce misclassification of non-adherence, some may still occur. Individuals who left their accommodation or had visitors for other reasons may have been adherent with the guidance if they did so because of exceptional circumstances. The addition of the "emergency medical treatment or hospital attendance" response option had no statistically significant impact on estimates of adherence to quarantine requirements in the third survey (12 to 17 July 2021). In the first two surveys (conducted 24 to and 14 to 19 June 2021), the only permitted reason respondents could report for leaving their accommodation was "to get or return a test for coronavirus (COVID-19)". Prior to the third International Arrivals Insights Survey (12 to 17 July 2021), respondents were not able to state "emergency medical treatment or hospital attendance" as a reason for leaving their accommodation and may have been miscategorised as non-adherent if leaving only for this reason, despite this reason being permitted. Respondents are deemed to be fully adherent to quarantine requirements if they report that they:ĭid not leave their accommodation for the full quarantine period, except to get or return a coronavirus (COVID-19) test, or to go for emergency medical treatment or hospital attendanceĭid not receive any visitors, except for visitors supporting their personal care Definitions and terms Adherence to quarantine requirements For the surveys that followed, the numbers were cleaned where possible using international telephone number convention information. This survey achieved 944 responses.ĭuring the pilot survey, there were some difficulties in connecting to international telephone numbers, which had been sourced from the PLF. This helped to simplify the questionnaire and shortened the median interview time to 17.6 minutes. In the second survey (14 to 19 June 2021), repeated questions were removed and respondents were asked instead about their behaviours across the whole quarantine period. The survey achieved 747 responses and the median interview time was 20.1 minutes. The pilot survey included repeated questions about the behaviour of respondents at different time points during quarantine, routed according to whether they took the required day two and day eight COVID-19 tests. The policy allowing international travel to restart, governed by a new traffic light system, was implemented on. Pilot surveyĪ pilot survey was conducted between 24 and with respondents who arrived in England on 14 May and. The statistics contained in this release are Experimental Statistics. Where a difference is statistically significant, we can be more confident that it really exists. Significance testing and confidence intervals have been used to test for differences. Percentages in these releases are weighted to account for age, sex and regional bias in response rates.Īs with all surveys, the estimates have an associated margin of error. The questions asked in this survey can be found in the Coronavirus COVID-19 Question Bank (XLS, 226KB). ONS experts were consulted on questionnaire design. Unless they tested positive for COVID-19, the majority of respondents have reached the end of their quarantine period at the time of interview. To minimise recall bias, respondents are interviewed between 10 and 14 days after arriving in England. The survey is conducted via telephone, and all responses are self-reported. Both UK and non-UK residents are included. The sample is stratified to be representative of the age, sex and regional distribution of the population arriving in England from amber list countries or territories. A PLF must be completed by everyone arriving in the UK from international travel, up to 48 hours beforehand. Respondents (adults aged 18 years and over) are randomly sampled using information from the passenger locator form (PLF), provided to the ONS by the DHSC. This survey was specifically designed to obtain information on people who have arrived from an amber list country or territory, are not exempt from quarantine requirements, and report that they are isolating at an address in England. The survey is produced, run and analysed in a collaboration between the Department for Health and Social Care (DHSC) and the Office for National Statistics (ONS). Prevalence of behaviour that poses a risk of transmitting COVID-19 The level of understanding and adherence to quarantine requirementsĪttitudes to quarantine and coronavirus (COVID-19) risk The International Arrivals Insights Survey was compiled in response to policy questions on the behaviour of individuals who have arrived in England from an amber list country or territory.
