An 8-item loneliness scale was administered to a sample of high school students (N = 1,710) twice, about one year apart. The scale exhibited good internal consistency reliability (alphas of 0.78 and 0.79, respectively), was relatively independent of gender effects, and demonstrated evidence of construct validity. Factor analysis of the items yielded a two-factor solution which met methodological criteria, but over-all the data suggested a method artifact, e.g., positively and negatively worded items factored separately. Examination of the two factors indicated the subscale of four negative items (lack companionship, no longer close, left out, feel isolated) had an alpha reliability of .77, correlated .89 with the total scale score, and exhibited virtually an identical pattern of associations with a set of theoretically relevant variables as the full scale. This four-item scale may be useful in epidemiologic surveys in which over-all response burden is an issue.
对1710名高中生样本进行了一项包含8个条目的孤独感量表测试，测试进行了两次，间隔约一年。该量表表现出良好的内部一致性信度（α系数分别为0.78和0.79），相对不受性别影响，并显示出结构效度的证据。对这些条目进行因子分析得到了一个符合方法学标准的双因子解决方案，但总体数据表明这是一种方法假象，例如，正向和负向表述的条目分别进行了因子分析。对这两个因子的检验表明，由四个负向条目（缺乏陪伴、不再亲密、被忽视、感到孤立）组成的子量表的α信度为0.77，与总量表得分的相关性为0.89，并且与一组理论相关变量的关联模式与总量表几乎相同。这个四项量表在总体应答负担是一个问题的流行病学调查中可能会有用。
