TY - JOUR AB - Purpose A wide range of variables, including cognitive, emotional and relational factors, could affect the level of peacefulness. The purpose of this paper is to examine key variables (theory of mind (ToM) and harmony) that mediate the personality trait of peacefulness.Design/methodology/approach The participants were 182 university students recruited from three universities in Isfahan, Iran. Some different scales were applied in order to measure the intended peace variables.Findings The findings demonstrate that ToM, as the ability to attribute mental states, significantly mediates the association between interpersonal peacefulness and inhibition skill, interpersonal peacefulness and conflict resolution abilities, and interpersonal peacefulness and level of aggression. In addition, harmony mediates the relationship between intrapersonal peacefulness, hope, intrapersonal peacefulness and self-compassionate competency.Practical implications These findings indicate that peaceful feelings enable a person to provide more attention to the concerns of others and to relationship issues.Originality/value This an original type of study in the field of peace psychology.
