To examine the factor structure, internal consistency, reliability, sex invariance, and discriminant validity of the French Canadian version of the Mental Health Continuum-Short Form (MHC-SF).
A total of 1485 French-speaking postsecondary students in Quebec, Canada (58% female; mean age = 18.4, SD = 2.4), completed the MHC-SF. Confirmatory factor analysis (CFA) was used to assess the factorial structure of the MHC-SF. Internal consistency was assessed with Cronbach's alpha, and reliability was assessed with the rho reliability coefficient. Invariance testing across sex was conducted using multigroup CFA comparing 4 increasingly restrictive models, and discriminant validity was examined against the Hospital Anxiety and Depression Scale (HADS) using Pearson correlation coefficients and CFA.
CFA supported the correlated 3-factor structure of the MHC-SF, with emotional, social, and psychological well-being subscales. The scale and each subscale items had internal consistency coefficients (Cronbach's alphas) above .70 and reliability coefficients (Jöreskog's rho) ranging from .79 to .90. Based on the multigroup CFA, configural, metric, scalar, and error variance invariance of the MHC-SF was observed across sex. Finally, the 2-continua model, suggesting that mental health and mental illness are distinct but related dimensions, was supported by both moderate inverse correlations between MHC-SF and HADS subscale scores and the 2-factor structure in CFA.
These data support the multidimensional structure of the MHC-SF and provide evidence of internal consistency, reliability, and invariance across sex. The MHC-SF is a valid and reliable measure of mental health that is distinct from mental illness among French Canadian young adults.
检验法裔加拿大人版心理健康连续体简表（MHC-SF）的因子结构、内部一致性、信度、性别不变性和区分效度。
加拿大魁北克省1485名说法语的高等院校学生（58%为女性；平均年龄 = 18.4，标准差 = 2.4）完成了MHC-SF测评。采用验证性因子分析（CFA）评估MHC-SF的因子结构。用克朗巴哈系数评估内部一致性，用rho信度系数评估信度。通过多组CFA比较4个限制程度递增的模型进行性别不变性检验，并使用皮尔逊相关系数和CFA对照医院焦虑抑郁量表（HADS）检验区分效度。
CFA支持MHC-SF的三因子相关结构，包括情绪、社会和心理健康子量表。该量表及其各子量表项目的内部一致性系数（克朗巴哈系数）均高于0.70，信度系数（约雷斯科格rho系数）在0.79至0.90之间。基于多组CFA，观察到MHC-SF在性别上具有构型、度量、标量和误差方差不变性。最后，MHC-SF与HADS子量表得分之间的中度负相关以及CFA中的双因子结构均支持双连续体模型，即心理健康和心理疾病是不同但相关的维度。
这些数据支持MHC-SF的多维结构，并提供了内部一致性、信度和性别不变性的证据。MHC-SF是一种有效且可靠的心理健康测量工具，在法裔加拿大青年中与心理疾病不同。
