Examining the common and specific grey matter abnormalities in childhood maltreatment and peer victimisation.

ABSTRACT:

Background

Early-life interpersonal stress, particularly childhood maltreatment, is associated with neurobiological abnormalities. However, few studies have investigated the neural effects of peer victimisation.

Aims

This study examines common and specific associations between childhood maltreatment, peer victimisation and brain structural alterations in youths.

Method

Grey matter volume (GMV) and cortical thickness data were collected from 105 age- and gender-matched youths (age range: 17-21 years). Region-of-interest and whole-brain analyses were conducted.

Results

For the region-of-interest analyses, the childhood maltreatment group had smaller GMV than controls in left inferior frontal gyrus, bilateral anterior insula, postcentral and lingual regions, which
