In 1978, Daniel Russell and colleagues published the UCLA Loneliness Scale, later revised as Version 3 in 1996. The instrument measures subjective loneliness through items about lacking companionship, feeling left out, and missing confiding relationships. High loneliness scores predict poorer sleep, immune function, and mood over time in longitudinal research cited by the National Institute of Mental Health.

The Quiz Hub built this loneliness test as a plain-language screener inspired by UCLA themes. It uses 22 original frequency items across emotional loneliness, social loneliness, and connectedness deficit rather than the full published scale. That trade-off favors readability for casual users while naming the Russell et al. source honestly. For mood-focused screening when sadness and withdrawal dominate, take our depression test. For broader wellbeing across mood, anxiety, sleep, and functioning, try our mental health test. For fear of judgment and social avoidance over two weeks, see our social anxiety test.

The Quiz Hub testWhat it adds

This loneliness testUCLA-inspired emotional, social, and connectedness domains with three screening bands and 988 on elevated results

Sample item: rating Often on lacking someone to turn to raises your emotional loneliness bar. Rating Very often on feeling left out raises connectedness deficit. Remote work, bereavement, and chronic illness can increase loneliness without reflecting a personality flaw.
