Abstract

Objective: To analyse the internal structure of the 28-item version of the General Health Questionnaire (GHQ-28), as well as its reliability and validity in relation to other variables in a sample of Ecuadorian university students. Method: Instrumental design with confirmatory factor analysis using weighted least square mean and variance adjusted (WLSMV) estimator, reliability and convergence and discrimination validity of the GHQ-28. Sample: 495 students (56.6% women), between 18 to 35 years old (M = 24.1 years; SD = 2.1), from three universities (59.6% public) in Ecuador. Results: The bifactor model of the GHQ-28 test has an adequate fit with χ2 = 357.81; p > .05; df = 322; χ2/df = 1.11; CFI = .991; TLI = .989; SRMR = .059; RMSEA = .015 [.000 – .023]; ωH = .93; ECV = .90; PUC = .78. The GHQ-28 is reliable and in terms of convergent validity, it correlates significantly and negatively with mental health, assessed by MHC-SF, and it is discriminant between risk and non-risk cases. Conclusion: The GHQ-28 bifactor model is replicable in Ecuadorian college students.

厄瓜多尔大学生一般健康问卷(GHQ-28)的心理测量特征

目的:分析厄瓜多尔大学生一般健康问卷(GHQ-28)的内部结构及其相对于其他变量的信度和效度。方法:采用加权最小二乘均方差调整(WLSMV)估计量进行工具设计和验证性因子分析，检验GHQ-28的信度、收敛度和判别效度。样本:495名学生(56.6%为女性)，年龄在18至35岁之间(M = 24.1岁;SD = 2.1)，来自厄瓜多尔的三所大学(59.6%是公立大学)。结果:GHQ-28检验的双因素模型拟合良好，χ2 = 357.81;P > 0.05;Df = 322;χ2 / df = 1.11;Cfi = .991;Tli = .989;SRMR = 0.059;Rmsea = .015 [.]000 - 0.023];ωh = .93;Ecv = 0.90;Puc = .78。GHQ-28具有较高的信度，在MHC-SF评估的收敛效度方面，GHQ-28与心理健康呈显著负相关，并且在风险病例和非风险病例之间具有区别性。结论:GHQ-28双因子模型在厄瓜多尔大学生中是可复制的。
