The effectiveness of multicomponent positive psychology interventions (MPPIs) on adolescents' mental health has been studied with the use of standard procedures throughout the scientific literature. However, little is known about the potential mechanisms underlying the network structure of mental health following the dual-factor model after an MPPI. We relied on network analysis to explore the reorganization of the connections between mental health indicators after a school-based MPPI. Adolescents from two high schools in Spain were randomly allocated to the 6-week intervention group (n = 85) or to the control group (n = 135). Network analysis showed that the relations between the two differentiated network dimensions of mental health (i.e. well-being and psychological distress) changed after the intervention. Unlike control participants, emotional well-being was negatively associated with depression and stress, while psychological well-being was positively related to stress after the intervention. The present study supports the viability of the network approach in analyzing the connections between mental health indicators as defined by the dual-factor model and the contribution of MPPIs to change the complex pattern of relations between the dimensions of well-being and psychological distress.

青少年多因素积极心理干预后心理健康网络结构的变化：有调节的网络分析

在整个科学文献中使用标准程序研究了多组分积极心理学干预 (MPPI) 对青少年心理健康的有效性。然而，对于 MPPI 之后的双因素模型下心理健康网络结构的潜在机制知之甚少。在基于学校的 MPPI 之后，我们依靠网络分析来探索心理健康指标之间联系的重组。西班牙两所高中的青少年被随机分配到 6 周干预组（n  = 85）或对照组（n = 135)。网络分析表明，心理健康的两个不同的网络维度（即幸福感和心理困扰）之间的关系在干预后发生了变化。与对照组不同，情绪健康与抑郁和压力呈负相关，而心理健康与干预后的压力呈正相关。本研究支持网络方法在分析由双因素模型定义的心理健康指标之间的联系以及 MPPI 对改变幸福和心理困扰维度之间复杂关系模式的贡献方面的可行性。
