Does childhood maltreatment make us more morally disengaged? The indirect effect of expressive suppression

The present cross-sectional study explored whether childhood maltreatment might lead to moral disengagement through emotion regulation strategies, i.e. expressive suppression and cognitive reappraisal. We examined these links in a convenience sample of 178 adults aged 18 to 56 (M = 22.50, SD = 4.89) who completed an online survey. Results suggested that expressive suppression was positively linked to emotioal and sexual abuse and moral disengagement. At the same time, cognitive reappraisal was negatively correlated with emotional abuse. Also, moral disengagement was significantly associated with physical and sexual abuse. Finally, mediation analysis results suggested a significant indirect effect of expressive suppression on the link between emotional and sexual abuse and moral disengagement (but not physical abuse) and moral disengagement. We discuss these findings through the lenses of moral psychology, focusing on moral disengagement as a potential reaction to childhood trauma through expressive suppression.
