Paweł Adamowicz, the liberal mayor of Gdańsk, Poland, died on January 14, 2019, after being stabbed by a man who rushed onstage during a charity event. Four studies were carried out to analyze the predictors of willingness to engage in collective action in support of the progressive city policies he initiated. In Study 1 (N = 214), collective angst was related to collective action intention. Identification with Gdańsk mediated this relation. In the next two studies, we tested the role of the perceived continuity of the in-group. The relationship between collective angst and willingness to support collective actions was mediated by perceived essentialist continuity of the group (Study 2, on snap election day, N = 121). Moreover, results confirmed that collective angst predicted strength of identification with Gdańsk. This identification was related to the perceived essentialist continuity of the group, which in turn was linked to willingness to engage in collective actions in support of progressive policies (Study 3, N = 98). In Study 4 (N = 456), conducted within a few days before the presidential election in Poland, we replicated the model of mediation obtained in Study 3, and showed that contextualized collective angst also predicted collective action intentions.

波兰格但斯克的自由市长PawełAdamowicz在一次慈善活动中被冲上舞台的一名男子刺伤后，于2019年1月14日去世。进行了四项研究，以分析愿意采取集体行动以支持他发起的进步城市政策的预测因素。在研究1（N = 214）中，集体焦虑与集体行动意图有关。与格但斯克的认同介导了这种关系。在接下来的两项研究中，我们测试了小组内感知连续性的作用。集体焦虑与支持集体行动的意愿之间的关系是由该团体的本质主义连续性所调解的（研究2，即席选举日，N= 121）。此外，结果证实集体焦虑可以预测与格但斯克的认同强度。这种认同与该团体的本质主义连续性有关，而后者又与愿意采取集体行动以支持进步政策的意愿有关（研究3，N = 98）。在波兰总统选举前几天进行的研究4（N = 456）中，我们复制了研究3中获得的调解模型，并表明情境化的集体焦虑也可以预测集体行动的意图。
