背景：社会支持强烈影响健康，但由于缺乏适合老年人使用的简短、廉价、心理测量学上合理的量表，研究受到限制。方法：随机抽取565名70岁及以上社区居民，对11项杜克社会支持指数（DSSI）进行效度和信度检验。结果：有效率为76%。参与者的平均年龄为76岁。使用cronbach alpha计算整体指数的内部一致性为0.77。重测信度（n=117）得分范围为0.70 ~ 0.81。同时效度与社会互动面试表具有中到强的相关关系。DSSI的结构效度与健康、生活质量和孤独感有中等相关性。为了进一步检验结构的效度，我们采用多元回归模型，用三个期望变量解释了25.6%的社会支持方差；自我评价健康、生活质量和生活安排。结论：强有力的证据表明，杜克社会支持指数的可靠性和有效性支持其在老年护理研究和健康促进策略中的应用。含义：DSSI为研究人员提供了使用社会支持的简短测量方法的机会，该方法专门对澳大利亚老年人进行了评估，而不是单项测量或有限的心理测量证据。
Background: Social support strongly influences health, but research has been limited by the paucity of brief, inexpensive, psychometrically sound scales suitable for use with older people.Method: The validity and reliability of the 11-item Duke Social Support Index (DSSI) were tested among a random sample of 565 community dwelling people aged 70 years and over.Results: A response rate of 76% was obtained. Participants had a mean age of 76 years. Internal consistency using Cronbachs alpha for the overall index was 0.77. Test-retest reliability (n=117) scores ranged from 0.70 to 0.81. Concurrent validity is supported by the DSSI's moderate to strong correlations with the interview Schedule for Social Interaction. Construct validity of the DSSI was supported by moderate correlations with health, quality of life and loneliness. To further test construct validity a multiple regression model was used and 25.6% of the variance in social support was explained using three expected variables; self rated health, quality of life, and living arrangements.Conclusion: Strong evidence for reliability and validity of the 11-item Duke Social Support Index support its use in aged care research and health promotion strategies.Implications: The DSSI provides researchers with the opportunity to use a brief measure of social support which has been assessed specifically with older Australians instead of single-item measures or scales which have limited psychometric evidence.
