PurposeOur aim was to identify the prevalence and correlates of loneliness, perceived and objective social isolation in the German population during the COVID-19 pandemic.MethodsData were taken from a representative survey with n = 3075 individuals (18–70 years; August/September 2021). Valid measures were used to quantify the outcomes (loneliness: De Jong Gierveld scale; perceived social isolation: Bude/Lantermann tool; objective social isolation: Lubben Social Network Scale). Multiple logistic regressions were used to identify the correlates of these three outcomes.ResultsThe prevalence of loneliness was 83.4%, the prevalence of perceived social isolation was 59.1% and the prevalence of objective social isolation was 28.9%. The prevalence rate significantly differed between the subgroups (e.g., the prevalence of perceived social isolation was 73.9% among individuals aged 18–29 years, whereas it was 48.8% among individuals aged 60–70 years). In regression analysis, several correlates of these outcomes were identified (e.g., marital status, age group (with changing signs), migration background, sports activities, or self-rated health).ConclusionOur study particularly identified very to extraordinarily high prevalence rates for social isolation and loneliness, respectively. Knowledge about the correlates (e.g., age group) may help to address these individuals during the ongoing pandemic.
