Abstract
This literature review examines how smartphone-based mobility data, aggregated and released by technology companies, were used to assess the effects of non-pharmaceutical interventions (NPIs) during COVID-19. Using a grounded theory approach, the author conducted a systematic search across Scopus, ACM, and Web of Science and analyzed 19 studies with three-phase coding and constant comparison. The review maps data sources and mobility metrics, shows how changes in movement were linked to NPIs and infection trends, and describes the geographic scales at which analyses were performed. It also synthesizes recurring themes about data quality, privacy, transparency, and the lack of standardized methods, noting that findings are sometimes inconsistent across studies. Overall, the review finds that mobility data can generate useful insights for understanding and managing person-to-person transmission at multiple scales, but ethical and methodological limitations and conflicting results constrain reliability and generalizability.
Dette litteraturstudie undersøger, hvordan smartphone-baserede mobilitetsdata, som er aggregeret og udgivet af teknologivirksomheder, blev brugt til at belyse effekterne af ikke-farmaceutiske indgreb (NPI) under COVID-19. Med en grounded theory-tilgang gennemførtes en systematisk søgning i Scopus, ACM og Web of Science, hvorefter 19 artikler blev analyseret med tre-faset kodning og løbende sammenligning. Gennemgangen kortlægger datakilder og mobilitetsmål, viser hvordan mobilitetsændringer blev sat i relation til NPI og smittespredning, og beskriver de geografiske niveauer, hvor analyserne fandt sted. Den samler også gennemgående temaer om datakvalitet, privatliv, transparens og manglen på standardiserede metoder og peger på, at resultaterne til tider er indbyrdes modstridende. Overordnet peger studiet på, at mobilitetsdata kan give nyttig viden til at forstå og håndtere person-til-person-smitte på flere skalaer, men etiske og metodiske begrænsninger samt modstridende fund udfordrer pålidelighed og generaliserbarhed.
