Addressing loneliness and social isolation in 52 countries: a scoping review of National policies.

Background: Even prior to the advent of the COVID-19 pandemic, there was ample evidence that loneliness and social isolation negatively impacted physical and mental health, employability, and are a financial burden on the state. In response, there has been significant policy-level attention on tackling loneliness. The objective of this scoping review was to conduct a loneliness policy landscape analysis across 52 countries of the UN European country groups. Our policy analysis sought to highlight commonalities and differences between the different national approaches to manage loneliness, with the goal to provide actionable recommendations for the consideration of policymakers wishing to develop, expand or review existing loneliness policies.

Methods: We searched governmental websites using the Google search engine for publicly available documents related to loneliness and social isolation. Seventy-eight documents were identified in total, from which 23 documents were retained. Exclusion of documents was based on predetermined criteria. A structured content analysis approach was used to capture key information from the policy documents. Contextual data were captured in a configuration matrix to highlight common and unique themes.

Results: We could show that most policies describe loneliness as a phenomenon that was addressed to varying degrees in different domains such as social, health, geographical, economic and political. Limited evidence was found regarding funding for suggested interventions. We synthesised actionable recommendations for the consideration of policy makers focusing on the use of language, prioritisation of interventions, revisiting previous campaigns, sharing best practice across borders, setting out a vision, evaluating interventions, and the need for the rapid and sustainable scalability of interventions.

Conclusions: Our study provides the first overview of the national loneliness policy landscape, highlighting the increasing prioritisation of loneliness and social isolation as a major public health and societal issue. Our findings suggest that policymakers can sustain this momentum and strengthen their strategies by incorporating rigorous, evidence-based intervention evaluations and fostering international collaborations for knowledge sharing. We believe that policymakers can more effectively address loneliness by directing funds to develop and implement interventions that impact the individual, the community and society.
