The well-being of young people in relation to their school performance has received increased attention in recent years. However, there is a lack of knowledge about the longitudinal and reciprocal relationship between adolescents’ subjective well-being and their academic achievements. The current study examined the bidirectional relationship between subjective well-being and academic achievement across two timepoints (T1 and T2) during the course of mid to late adolescence, i.e., in school year 9 (age 15), and school years 11–12 (ages 17–18). The study also investigated variation in the association as a function of adolescent gender. Data on subjective well-being and teacher-assigned school grades of 723 adolescents (48.7% girls) residing in Sweden were analyzed by estimating a series of cross-lagged path models. The findings suggest gender differences in the relationship as no associations were found among boys. Support for a bidirectional relationship between the constructs was only found for girls. For girls, higher subjective well-being at T1 was associated with higher academic achievements at T2, while higher academic achievements at T1 was associated with lower subjective well-being at T2. These findings highlight that the subjective well-being of adolescent girls may be important for their ability to perform at school, but their academic achievements may also inflict negatively on their subjective well-being.

近年来，与他们的学校表现有关的年轻人的福祉受到了越来越多的关注。但是，对于青少年的主观幸福感与学业成绩之间的纵向和相互关系，缺乏了解。本研究调查了青春期中期至青春期后期两个阶段（T1和T2），即在9年级（15岁）和11-12年级（11-12岁）的主观幸福感与学业成绩之间的双向关系。 17-18岁）。这项研究还调查了随着青春期性别而变的联想变化。通过估计一系列交叉滞后路径模型，分析了居住在瑞典的723名青少年（占女孩的48.7％）的主观幸福感和老师指定的学校成绩的数据。研究结果表明，男女之间的关系存在性别差异，因为男孩之间没有关联。仅在女孩中支持结构之间的双向关系。对于女孩来说，在T1时主观幸福感较高与在T2时较高的学业成绩相关，而在T1时较高的学业成绩与T2上的较低主观幸福感相关。这些发现表明，青春期女孩的主观幸福感对他们在学校的表现能力可能很重要，但其学业成绩也可能对其主观幸福感产生负面影响。T1的较高主观幸福感与T2的较高学业成绩相关，而T1的较高学术成绩与T2的较低主观幸福感相关。这些发现表明，青春期女孩的主观幸福感对他们在学校的表现能力可能很重要，但其学业成绩也可能对其主观幸福感产生负面影响。T1的较高主观幸福感与T2的较高学业成绩相关，而T1的较高学术成绩与T2的较低主观幸福感相关。这些发现表明，青春期女孩的主观幸福感对他们在学校的表现能力可能很重要，但其学业成绩也可能对其主观幸福感产生负面影响。
