AIMS
The purpose of this study is to analyze the internal consistency, factor structure, and external validity of the 12-item General Health Questionnaire (GHQ-12) among older adults in India.
SETTINGS AND DESIGN
This study analyzes data collected as part of the UNFPA "Building Knowledge Base on Ageing in India (BKPAI)" project. The BKPAI Survey was conducted in 2011 in seven major demographically advanced states of India - Himachal Pradesh, Punjab, West Bengal, Odisha, Maharashtra, Kerala, and Tamil Nadu.
MATERIALS AND METHODS
A community-based representative sample of 9692 respondents aged 60 and above from seven Indian states was employed. The GHQ-12 questionnaire was administered.
STATISTICAL ANALYSIS
The Cronbach's alpha was calculated to analyze internal consistency. Factor analysis was applied to explore the factor structure of GHQ-12, and then correlation coefficients were calculated to examine the external validity of the measurement.
RESULTS
The Cronbach's alpha of the GHQ-12 is 0.9. Factor analysis reveals two significant components which accounted for 59% of the variance. The correlation between the overall score of GHQ-12 and the subjective well-being inventory (SUBI) is 0.58.
CONCLUSIONS
The GHQ-12 shows adequate reliability among the older population in India.
目的
本研究旨在分析12项一般健康问卷（GHQ - 12）在印度老年人中的内部一致性、因子结构和外部效度。
设置与设计
本研究分析了作为联合国人口基金“印度老龄化知识库建设（BKPAI）”项目一部分收集的数据。BKPAI调查于2011年在印度人口统计学上较为发达的七个主要邦进行——喜马偕尔邦、旁遮普邦、西孟加拉邦、奥里萨邦、马哈拉施特拉邦、喀拉拉邦和泰米尔纳德邦。
材料与方法
采用了来自印度七个邦的9692名60岁及以上受访者的基于社区的代表性样本。实施了GHQ - 12问卷。
统计分析
计算克朗巴哈系数以分析内部一致性。应用因子分析来探索GHQ - 12的因子结构，然后计算相关系数以检验该测量的外部效度。
结果
GHQ - 12的克朗巴哈系数为0.9。因子分析揭示了两个显著成分，它们占方差的59%。GHQ - 12的总分与主观幸福感量表（SUBI）之间的相关性为0.58。
结论
GHQ - 12在印度老年人群体中显示出足够的可靠性。
