This study investigates the role of Positive Affect as a predictor of Psychological Well-Being in 43,653 12-year-old children from 29 countries, using a Structural Equation Model. The model’s potential gender and nationality equivalences were also examined. Data was sourced from the International Child Well-Being Survey. The ‘happy’ item was found to be the most effective in capturing the Positive Affect construct, with Psychological Well-Being showing moderately high levels. A strong positive correlation was observed between Positive Affect and Psychological Well-Being, with Positive Affect explaining 70.1% of the variance in Psychological Well-Being. The model proved invariant at the metric level across countries and at the strict level between genders. In conclusion, Positive Affect is a significant predictor of Psychological Well-Being, though cultural factors contributed to country-specific variations.

来自 29 个国家的 12 岁儿童积极情绪与心理健康之间的关系和可预测性

本研究使用结构方程模型，对来自 29 个国家的 43,653 名 12 岁儿童的积极影响作为心理健康预测因子的作用进行了调查。还检查了该模型的潜在性别和国籍等同性。数据来源于国际儿童福祉调查。研究发现，“快乐”项目在捕捉积极情感结构方面最有效，心理健康程度较高。积极情绪与心理健康之间存在很强的正相关性，积极情绪解释了心理健康差异的 70.1%。事实证明，该模型在各国的公制水平以及严格的性别水平上都保持不变。总之，积极影响是心理健康的重要预测因素，尽管文化因素导致了国家特定的差异。
