Boosting attachment security promotes prosociality: The mediating effect of moral disengagement.

Abstract

While attachment security is known to promote prosocial behaviour, a closer examination is needed to clarify the active mechanism in this relationship. We addressed this issue by examining the mediation effect of moral disengagement in two studies. Participants were assigned to the control priming group or the attachment security priming group. After the priming procedure, they completed the measurements of a sense of security, moral disengagement and prosocial behaviour. The results from both studies showed that compared with control priming, attachment security priming enhanced prosociality. Furthermore, mediation analysis showed that moral disengagement mediated the relationship between attachment security and prosociality. The present findings extend the understanding of the underlying mechanisms of attachment security and prosociality, and provide insights into the effectiveness of boosting attachment security in intervening in moral disengagement.
