While 3,335 (41%) of respondents could see no reason not to install the App, the remaining 59% of respondents selected at least one option from a list of 10 options. “I worry technology companies will use this as an excuse for greater surveillance after the pandemic” was selected by 3,342 (41%) respondents, “I worry the government would use this as an excuse for greater surveillance after the pandemic” was selected by 2,636 (33%) people and “I worry that my phone would be more likely to get hacked” was selected by 1,742 (22%) of respondents.
In terms of preference for choice of the App technology, 3,907 (48%) of total respondents stated it did not matter to them. For the 4,181 who expressed a preference, 1,569 (38% of this group) preferred a Bluetooth-only App, 1,344 (32%) were unsure, 738 (18%) would like an App that uses Bluetooth and Geolocation technology and 530 (13%) would like to see a Geolocation-only App.
Weighted analyses
Initially 58% percent of respondents indicated they “definitely will install” the App, with a further 25% indicating they “probably will install” the App. Eight percent indicated they “may or may not install”, 3% indicated they “probably won’t install” while 6% stated they “definitely won’t install” the App. Following several questions containing more detailed information about the technologies involved in contact tracing Apps and some potential push and pull factors regarding adoption (see Table 1), 54% of respondents indicated they “definitely will install” the App, 30% indicated they “probably will install” the App and 7% indicated they “may or may not install” the App. Selection of the two remaining options for this question did not change.
There is evidence for an association between gender and unwillingness to install the App, with males more likely to respond that they probably or definitely won’t install the app (11% vs 6% in females). There is also evidence for an association with age group, with the oldest and youngest groups most likely to indicate they probably or definitely will install the App. Finally, COVID related worry was associated with willingness to install – those “Not At All Worried” about COVID were far more likely to respond that they “definitely won’t install” the App (34% vs 6% or lower in those more worried about COVID).
