Although loneliness has received increased attention in the public discourse and social media, more effort is needed to better understand this phenomenon and to develop and implement policies and interventions to combat its potential detrimental effects on the well-being and quality of life of older people. As a starting point, it is important to differentiate between different definitions, that are often used interchangably when reffering to loneliness. Loneliness, social isolation and being alone are distinct concepts. Loneliness should also not be mixed with depression. While there exists various definitions, loneliness is generally understood to be a negative, unpleasant feeling and experience that occurs when there is a discrepency between a person’s actual and desired social relationships. It is also very subjective. Social isolation, by contrast, concerns an objective experience of reduced social intercations and social ties. This study focused on both loneliness and social isolation. It identified relevant literature regarding the main factors associated with loneliness and social isolation and analysed results on the prevalence and different aspects of loneliness and social isolation from a European comparative perspective. Finally, it showcased a number of examples and good practice of targeted interventions from across Europe.
