Can Emotion Regulation Affect Aggressive Responses? A Study on the Ukrainian–Russian Conflict in a Non-Directly Exposed Sample

On 24 February, Russian President Vladimir Putin gave the order to invade neighbouring Ukraine; a typical trend during the war is considering events in a one-sided way, emphasising the exclusive contribution of one opponent over the other for the outbreak of war. War may trigger the experience of emotions, such as anger, shame, and disgust. The present study reproduces previous studies on the influence of emotional regulation in support of aggressive reactions (AR) in the Israeli–Palestinian conflict. A questionnaire referring to the Russian–Ukrainian conflict has been implemented and spread in the Italian territory. A multiple moderated mediation model was proposed to evaluate the effect of emotional cognitive reappraisal on the propensity for AR, including conflict-related emotions (anger, shame, disgust) as mediators and political alignment and the appraisal of one’s own emotions subscale of the brief emotional intelligence scale as moderators. The results show that cognitive reappraisal of emotions has a negative effect on AR; moreover, recognising and regulating emotions decreases anger, while taking sides with Ukraine or not siding seems to have an effect on AR depending on the emotion felt (anger or shame). The results are discussed according to the current literature on the topic, highlighting the practical implications and limits of the research.
