ULS-8孤独感量表信效度检验及其应用

目的:探讨ULS-8孤独感量表在农村社区老年人中的信度、效度。方法:通过面对面访谈, 在839名农村社区老年人中完成问卷调查, 对部分研究对象两周后实施重测。结果:探索性因素分析结果发现ULS-6 (剔除条目3和条目6后)符合原文的理论构想;ULS-6总量表的Cronbach's α系数为0.831, 重测信度为0.715, 条目与总分的相关系数均具有统计学意义;经统计学检验, 总量表得分与老年人生活质量、社会支持、自杀意念、重性抑郁发作均显著相关, 证明ULS-6量表具有较好的实证效度。结论:ULS-6量表信度、效度均较好, 符合心理学测量的要求, 可以用于我国农村社区老年人中孤独感的调查。

Reliability and validity of ULS-8 loneliness scale in elderly samples in a rural community

Objective: To explore the reliability and validity of the short-form of the UCLA loneliness scale (ULS-8) among Chinese rural community-dwelling elderly.
Methods: ULS-8 was used for 839 Chinese rural community-dwelling elderly during face-to-face interviews.
Results: After deleting item-3 (I am an outgoing person) and item-6 (I can find companionship when I want it), the exploratory factor analysis showed that the construction of the new scale (ULS-6) fit the original construction of ULS-8, a single-factor resolution. Cronbach’s α coefficient of ULS-6 was 0.831. Test-retest reliability was 0.715. All item-total correlations reached statistical significance. The total score of ULS-6 was correlated to quality of life, social support, suicidal ideation, and current major depression episode.
Conclusion: ULS-6 shows satisfactory reliability and validity and meets the needs of psychometric properties, and can be used for the evaluation of loneliness among Chinese rural elderly.
