UCLA Loneliness Scale

The UCLA Loneliness Scale is a questionnaire used by researchers and mental health professionals to measure how often someone feels lonely or disconnected from others. It asks about feelings of social isolation, companionship, and belonging. The scale helps identify individuals who may need support, by quantifying their perceived loneliness. It’s useful for understanding how loneliness impacts mental and physical health, and for tracking changes over time or in response to interventions. Overall, it provides a standardized way to assess a person's subjective experience of loneliness in a reliable manner.
