Our aim was to examine measurement invariance of the Flourishing Scale (FS)-a concise measure of psychological wellbeing-across two study samples and by population characteristics among Canadian adolescents. Data were retrieved from 74,501 Canadian secondary school students in Year 7 (2018-2019) of the COMPASS Study and from the original validation of the FS ( = 689). We assessed measurement invariance using a confirmatory factor analysis in which increasingly stringent equality constraints were specified for model parameters between the following groups: study sample (i.e., adolescents vs. adults), gender, grade, and ethno-racial identity. In all models, full measurement invariance of the FS across all sub-groups was demonstrated. Our findings support the validity of the FS for measuring psychological wellbeing among Canadian adolescents in secondary school. Observed differences in FS score among subgroups therefore represent true differences in wellbeing rather than artifacts of differential interpretation.
我们的目的是检验 Flourishing Scale（FS）——一种简洁的心理幸福感衡量标准——在两个研究样本和加拿大青少年的人口特征中的测量不变性。数据来自于 COMPASS 研究的 74501 名加拿大中学 7 年级（2018-2019 年）的学生和 FS 的原始验证（n=689）。我们使用验证性因素分析来评估测量不变性，其中在以下组之间为模型参数指定了越来越严格的相等约束：研究样本（即青少年与成年人）、性别、年级和族裔身份。在所有模型中，FS 在所有子组中的完全测量不变性都得到了证明。我们的研究结果支持 FS 在加拿大中学青少年中测量心理幸福感的有效性。因此，子组之间 FS 得分的差异代表了幸福感的真实差异，而不是解释差异的假象。
