Loneliness Test

Take the UCLA-3 loneliness screener and explore what loneliness research says about connection, health, and evidence-based interventions.

What Is Loneliness?

Loneliness is the subjective, distressing feeling that arises when perceived social relationships fall short of desired ones. It is distinct from objective social isolation, a person can be surrounded by people and feel profoundly lonely, or live alone and feel deeply connected.

The UCLA Loneliness Scale, developed by researchers at UCLA and revised multiple times, is the most widely used measure of loneliness in adults. The 3-item version (UCLA-3) captures the core construct in under a minute and is validated for population surveys and clinical screening.

Loneliness is now recognized as a significant public health concern, chronic loneliness carries health risks comparable to smoking 15 cigarettes per day (a major meta-analysis by Holt-Lunstad).
