UCLA Loneliness Scale

The UCLA Loneliness Scale is a commonly used measure of loneliness. Its name derives from its having been developed at the University of California, Los Angeles (UCLA). It was first published in 1978 by Russell, D., Peplau, L.A., and Ferguson, M.L., and was revised in 1980 and 1996. Developer Daniel Russell has expressed concern that publication of the scale could skew responses.
