The Association Between Child Maltreatment and Moral Disengagement: A Three-Level Meta-Analytic Review

Area of Science:

• Psychology
• Developmental Psychology
• Social Psychology

Background:

• Moral disengagement facilitates distancing from moral standards and rationalizing unethical conduct.
• Existing research indicates a link between child maltreatment and heightened moral disengagement, but findings vary.
• Inconsistencies in the literature necessitate a quantitative synthesis to clarify the child maltreatment-moral disengagement relationship.

Purpose of the Study:

• To systematically evaluate the strength of the association between child maltreatment and moral disengagement.
• To investigate potential moderating factors influencing this relationship across diverse populations.
• To provide empirical evidence for developing targeted interventions for individuals affected by childhood adversity.

Main Methods:

• A comprehensive systematic literature review was conducted across four major databases.
• Meta-analytic synthesis using three-level modeling in R was employed to analyze data from 27 primary studies (N=24,611).
• Moderator analyses were performed to examine differential effects based on sex, measurement tools, and moral disengagement categories.

Main Results:

• A significant positive association was found between child maltreatment and moral disengagement (r=0.262, p < .001).
• The association was notably stronger in males compared to females.
• The strength of the relationship varied depending on the specific measurement of moral disengagement and its categorization.

Conclusions:

• Child maltreatment is consistently linked to increased moral disengagement, highlighting the psychological impact of early adversity.
• Intervention programs should adopt trauma-informed approaches to effectively address the moral consequences of child maltreatment.
• Future research should consider sex-specific differences and refine measurement strategies for moral disengagement in trauma populations.
