About the UCLA Loneliness Scale

The UCLA Loneliness Scale is the most widely used validated measure of subjective loneliness. The abbreviated 3-item version used here was validated by Hughes et al. (2004) as a reliable screening tool for population research. It measures perceived social isolation — the subjective feeling of being alone — rather than objective social contact frequency. These are distinct: you can be surrounded by people and feel lonely, or live alone and feel well-connected.

Loneliness as a Health Issue

Loneliness is increasingly recognised as a public health concern. A meta-analysis by Holt-Lunstad et al. (2015) of 148 studies found that social isolation increases mortality risk by 29%. The UK appointed the world's first Minister for Loneliness in 2018, reflecting growing recognition of its health impact. Loneliness affects an estimated 9 million adults in the UK alone.
