The OPN has expanded to include questions on other topics of national importance, such as health and the cost of living.</p><p>For more information about the survey and its methodology, see the gov.uk <a href="ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/healthandlifeexpectancies/methodologies/opinionsandlifestylesurveyqmi">OPN Quality and Methodology Information</a> (QMI) webpage.</p><p><strong>Changes over time</strong></p><p>Up to March 2018, the OPN was conducted as a face-to-face survey.

From April 2018 to November 2019, the OPN changed to a mixed-mode design (online first with telephone interviewing where necessary). Mixed-mode collection allows respondents to complete the survey more flexibly and provides a more cost-effective service for module customers.</p><p>In March 2020, the OPN was adapted to become a weekly survey used to collect data on the social impacts of the coronavirus (COVID-19) pandemic on the lives of people of Great Britain.

These data are held under Secure Access conditions in SN 8635, <em>ONS Opinions and Lifestyle Survey, 2019-2023: Secure Access</em>. (See below for information on other Secure Access OPN modules.)</p><p>From August 2021, as coronavirus (COVID-19) restrictions were lifted across Great Britain, the OPN moved to fortnightly data collection, sampling around 5,000 households in each survey wave to ensure the survey remained sustainable.</p><p> </p><p><strong>Secure Access OPN modules</strong><br><br>Besides SN 8635 (which includes the COVID-19 Module), other Secure Access OPN data includes sensitive modules run at various points from 1997-2019, including Census religion (SN 8078), cervical cancer screening (SN 8080), contact after separation (SN 8089), contraception (SN 8095), disability (SNs 8680 and 8096), general lifestyle (SN 8092), illness and activity (SN 8094), and non-resident parental contact (SN 8093).
