Influence of Child Abuse and Neglect on Psychopathy

Area of Science:

• Psychology
• Forensic Psychology
• Developmental Psychology

Background:

• Psychopathy is a personality construct linked to antagonism (meanness), fearless dominance (boldness), and impulsivity (disinhibition).
• Childhood abuse and neglect are recognized risk factors for adult psychopathy.
• Limited research exists on the differential impact of specific childhood adversities on contemporary measures of psychopathy.

Purpose of the Study:

• To investigate the relative influence of various forms of child abuse and neglect on adult psychopathy.
• To examine these associations using a composite measure of psychopathy that includes meanness, boldness, and disinhibition.
• To explore potential differences in these relationships across different samples and genders.

Main Methods:

• Structural equation modeling (SEM) using a partial least squares (PLS) approach was employed.
• Data were collected from two distinct samples: 435 college students and 399 adults recruited online.
• Psychopathy was assessed using contemporary instruments measuring meanness, boldness, and disinhibition.

Main Results:

• Childhood physical neglect emerged as the most significant predictor of adult psychopathy across both samples.
• The influence of other types of child abuse and neglect on psychopathy varied between the college student sample and the online adult sample.
• Gender moderated the relationship between certain forms of childhood adversity and adult psychopathy.

Conclusions:

• Childhood physical neglect plays a crucial role in the development of adult psychopathy.
• The specific pathways from childhood adversity to psychopathy are complex and influenced by sample characteristics and gender.
• Findings highlight the importance of considering specific forms of maltreatment and demographic factors in understanding the developmental origins of psychopathy and informing interventions.
