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). Russell, D., Peplau, L.A., and Ferguson, M.L., first published it in 1978, and it was revised in 1980 and 1996. Developer Daniel Russell has expressed concern that publication of the scale could skew responses.
The scale is widely used in the scientific literature. The Revised UCLA Loneliness Scale is cited to "has been used in an estimated 80% of all empirical studies on loneliness".
