Research on adolescents’ psychological well-being has been rare and lacks a sound theoretical framework. The International Survey of Children’s Well-Being (ISCWeB) is using the Children’s Worlds Psychological Well-Being Scale (CW-PSWBS) as a measure based on Ryff’s model of psychological well-being. However, both Ryff’s model appropriateness to adolescent population and its cross-country comparability are unclear. In order to cross-country compare statistics obtained from adolescents by using this instrument, its measurement invariance needs to be checked. The aim of this paper is to test the fit and the cross-country comparability of CW-PSWBS among 13 countries using 12-year-olds samples from ISCWeB survey wave 2 and 3. Multi-group confirmatory factor analysis to assess the extent to which it is valid to make cross-national comparisons using this measure has been used. Our results suggest that it is meaningful to compare correlations and regressions of a 5-item version of CW-PSWBS scale only in wave 2 data, when the item on self-acceptance dimension is left out. In wave 3, one additional item does not get support for metric invariance. However, scalar invariance is not supported in any case and therefore cross-national comparisons of mean scores on CW-PSWBS are not statistically meaningful.

对青少年心理健康的研究很少，缺乏完善的理论框架。国际儿童幸福感调查 (ISCWeB) 正在使用儿童世界心理幸福感量表 (CW-PSWBS) 作为基于 Ryff 心理幸福感模型的衡量标准。然而，Ryff 模型对青少年人群的适用性及其跨国可比性尚不清楚。为了对使用该工具从青少年中获得的统计数据进行跨国比较，需要检查其测量不变性。本文的目的是使用来自 ISCWeb 调查第 2 波和第 3 波的 12 岁儿童样本，测试 CW-PSWBS 在 13 个国家/地区的拟合度和跨国可比性。已使用多组验证性因素分析来评估使用该措施进行跨国比较的有效程度。我们的结果表明，当忽略自我接受维度的项目时，仅在第 2 波数据中比较 CW-PSWBS 量表的 5 项版本的相关性和回归是有意义的。在第 3 波中，一个额外的项目没有得到对度量不变性的支持。然而，在任何情况下都不支持标量不变性，因此 CW-PSWBS 平均分数的跨国比较没有统计意义。一项额外的项目不支持度量不变性。然而，在任何情况下都不支持标量不变性，因此 CW-PSWBS 平均分数的跨国比较没有统计意义。一项额外的项目不支持度量不变性。然而，在任何情况下都不支持标量不变性，因此 CW-PSWBS 平均分数的跨国比较没有统计意义。
