Résumé	Multidimensional loneliness assessment treats loneliness not as simple aloneness but as the distressing perceived gap between the social relationships a person wants and the ones they actually have. This cognitive-discrepancy view, rooted in Robert Weiss's distinction between emotional and social loneliness, holds that the absence of an intimate attachment produces a different, qualitatively distinct loneliness from the absence of an engaging social network. Daniel Russell's 1996 psychometric work, developing the third version of the UCLA Loneliness Scale, established the measurement properties, factor structure, reliability, and validity that anchor the broader assessment tradition. The framework matters enormously for gerontology because loneliness in later life is a strong, independent predictor of depression, cognitive decline, and mortality, yet it does not reduce to objective isolation. Measuring it well requires capturing the subjective adequacy of relationships across both intimate and network dimensions. The approach gives researchers reliable, validated instruments and a clear conceptual model of what loneliness is and how it should be scored.	The UCLA Loneliness Scale is a widely used instrument for measuring subjective feelings of loneliness and social isolation. Developed by Daniel Russell in the late 1970s, the scale measures the discrepancy between desired and actual social relationships. The UCLA LS has become the gold standard in loneliness research and is used across clinical, epidemiological, and social psychology studies worldwide.
