Several measures that assess loneliness have been developed for adults. Across three studies, we investigated psychometric features of scores of different versions of the Rasch-Type Loneliness Scale, the University of California Los Angeles Loneliness Scale, and three single-item measures. In Study 1 (N = 697 self-ratings, N = 282 informant-ratings of 160 targets) and Study 2 (N = 1,216 individuals from 608 couples), we investigated convergent validity, self-informant agreement, and nomological nets of the item scores using correlates related to demographic aspects, personality, satisfaction, and network characteristics. In Study 3 (N = 411), we estimated a reliability of rxx>.70$r_{xx}>.70$$r_{xx}>.70$ for scores of three single-item measures of loneliness. Overall, scores of all measures and their nomological nets were highly correlated within and across studies, indicating that the scores of the included measures are all reliable and valid. Recommendations for choosing a loneliness measure are discussed.

已经为成年人制定了几种评估孤独感的措施。在三项研究中，我们调查了不同版本的 Rasch 型孤独感量表、加州大学洛杉矶分校孤独感量表和三个单项测量值的心理测量特征。在研究 1（N = 697 个自我评价，N = 160 个目标的 282 个线人评级）和研究 2（N = 608 对夫妇的 1,216 个人）中，我们调查了收敛有效性、自我信息一致性和项目的法则网使用与人口统计方面、个性、满意度和网络特征相关的相关因素进行评分。在研究 3 ( N = 411) 中，我们估计了r×× _> 。70$r_{XX}>.70$$r_{xx}>.70$三个单项孤独感测量值。总体而言，所有措施的分数及其法则网在研究内部和研究之间高度相关，表明所包含措施的分数都是可靠和有效的。讨论了选择孤独感测量的建议。
