The identification of factors that counter youth’s radicalization while promoting democratic activism is a timely social issue. This paper examines the association of psychological well‐being (PWB) with violent radicalism and nonviolent activism, by focusing on the mediating role of both social disconnectedness (SD) and the perceived illegitimacy of the authorities (PIoA). Two mediation structural equation models (full vs. partial) were applied to data collected from 328 Italian adolescents (14–19 years). The results showed how SD and PIoA fully mediated the link of PWB with radicalism (negatively) and activism (positively). This model was further supported when compared with an alternative one proposing PWB as a mediator between SD and PIoA. The findings are discussed in light of the existing literature and provide potential implications for practice.

青少年心理健康、激进主义和激进主义：社会脱节和当局非法的中介作用

确定在促进民主激进主义的同时对抗青年激进化的因素是一个及时的社会问题。本文通过关注社会脱节 (SD) 和感知的当局非法性 (PIoA) 的中介作用，研究了心理健康 (PWB) 与暴力激进主义和非暴力激进主义的关联。两种中介结构方程模型（完整与部分）应用于从 328 名意大利青少年（14-19 岁）收集的数据。结果表明 SD 和 PIoA 如何完全调节 PWB 与激进主义（消极）和激进主义（积极）之间的联系。与提议 PWB 作为 SD 和 PIoA 之间中介的替代模型相比，该模型得到了进一步支持。
