The study is aimed to examine the psychometric characteristics of the Duke Social Support Scale (DSSI) in young rural Chinese individuals (379 suicides, 411 controls) aged 15-34 years. Social support was measured by 23-item DSSI, which included Social Interaction Scale, Subjective Social Support, and Instrumental Social Support. DSSI had high internal consistency (alphas all over .79) and correlated with hopelessness and anxiety in both samples. Confirmatory factor analysis showed that the structure models of DSSI were basically suitable for the original structure of DSSI but some items should be modified or deleted. Altogether, these findings support that DSSI has high reliability and validity, which makes it an acceptable measure for social support in young Chinese populations. However, further model tests should be carried out by deleting or modifying some items or being used in different populations.
本研究旨在检验杜克社会支持量表(DSSI)在 15-34 岁的年轻农村中国个体(379 例自杀者,411 例对照者)中的心理测量学特征。社会支持采用 23 项 DSSI 进行测量,包括社会互动量表、主观社会支持和工具性社会支持。DSSI 具有较高的内部一致性(所有 α 值均高于.79),并与两个样本中的绝望和焦虑相关。验证性因子分析表明,DSSI 的结构模型基本适用于 DSSI 的原始结构,但某些项目需要修改或删除。总的来说,这些发现支持 DSSI 具有较高的信度和效度,使其成为年轻中国人群体社会支持的一种可接受的测量方法。然而,进一步的模型测试应该通过删除或修改一些项目或在不同的人群中使用来进行。
