METHODS: The study collected 600 valid samples from individuals aged 55 and above to examine the psychometric properties of the developed SDQO. Item analysis was conducted to assess the performance of each item, and exploratory factor analysis (EFA) was employed to analyze its initial structure and eliminate less ideal items. Subsequently, confirmatory factor analysis (CFA) was used to examine the model fit of the suggested structure by EFA, using different subsamples. Internal consistency, concurrent validity, and other analyses were also performed.
RESULTS: The original 27-item SDQO was reduced to 17 items after removing 4 questions in item analysis and 6 questions in EFA. The Cronbach\'s alpha for the 17-item version of SDQO was 0.80. Both EFA and CFA supported its 6-factor structure, with factors identified as community activities, loneliness, personal resources, leisure activities, friendship, and family resources. SDQO also demonstrated expected performance in concurrent validity.
CONCLUSIONS: The 17-item version of SDQO exhibited good reliability and validity, measuring various aspects of social detachment behavior, feelings, and resources. It holds value for future research applications.
方法:该研究从55岁及以上的个体中收集了600份有效样本,以检查开发的SDQO的心理测量特性。进行项目分析以评估每个项目的性能,并采用探索性因子分析(EFA)分析其初始结构并消除不太理想的项目。随后,验证性因子分析(CFA)用于检查EFA建议结构的模型拟合,使用不同的子样本。内部一致性,并发有效性,和其他分析也进行了。
结果:在删除项目分析中的4个问题和EFA中的6个问题后,原始的27个项目SDQO减少到17个项目。17项SDQO版本的Cronbach的alpha为0.80。EFA和CFA都支持其6因素结构,被确定为社区活动的因素,孤独,个人资源,休闲活动,友谊,家庭资源。SDQO还展示了在并发有效性方面的预期性能。
结论:SDQO的17项版本具有良好的信度和效度,衡量社会超脱行为的各个方面,感情,和资源。它对未来的研究应用具有价值。
