Drivers of acceptance of COVID-19 proximity tracing apps in Switzerland: a panel survey analysis
ABSTRACT
Background:
Digital proximity tracing (DPT) apps have been released to mitigate SARS-CoV-2 transmission. But it remains unclear how their acceptance and uptake can be improved.
Objective:
The aim of this study was to investigate SwissCovid app coverage and reasons for not using the app in Switzerland during a time of increasing SARS-CoV-2 incidence.
Methods:
By use of data collected between 28.09.2020 to 08.10.2020 for a nationwide online panel survey (Covid-19 Social Monitor, n=1’511 participants), socio-demographic and behavioral factors associated with app usage were examined using multivariable logistic regression. Reasons for app non-use were analyzed descriptively.
Results:
Overall, 46.5% of participants reported to use the SwissCovid app (up from 43.9% in a study wave conducted in July 2020). A higher monthly household income (e.g. OR 1.92 [1.40-2.64] for an income >CHF 10’000 vs. an income ≤ CHF 6’000), more frequent internet use (e.g., daily (reference) vs. less than weekly OR 0.37 [0.16-0.85]), better adherence to mask wearing recommendations (e.g., always or most of time (reference) vs. rarely or never OR 0.28 [0.15-0.52]), and being a non-smoker (OR 1.32 [1.01-1.71]) were associated with an increased likelihood for app uptake. Citizenship status (e.g., non-Swiss citizenship 0.61 [0.43-0.87] vs. Swiss citizenship only), and language region (French 0.61 [0.46-0.80], vs. Swiss German) were associated with a lower app uptake probability. In a randomly selected subsample (n=711) with more detailed information, higher levels of trust in government and health authorities was additionally associated with a higher app uptake probability (e.g., OR 3.13 [1.58-6.22] for high vs. low trust (reference)). The most frequent reasons for app non-use was lack of perceived benefit of the app (36.8%), 22.8% reported to have no compatible phone, and 22.4% had privacy concerns.
Conclusions:
Removing technical hurdles and communicating the benefits of DPT-apps are crucial to promote further uptake, compliance, and ultimately to enhance effectiveness of DPT-apps for pandemic mitigation.
