Abstract

Psychopathy-related paralimbic and limbic structural brain abnormalities have been implicated in incarcerated adult and adolescent male samples. However, there have been few neuroimaging studies of psychopathic traits in females in general and no studies from incarcerated female youth in particular. Here we present the first study to examine the relationship between brain gray matter volumes and psychopathic traits (assessed using the Psychopathy Checklist-Youth Version [PCL-YV]) in a sample of maximum-security incarcerated female adolescents (N = 39; mean age = 17.6 years). Consistent with male samples, regional gray matter volumes were negatively related to psychopathic traits in female youth offenders in limbic and paralimbic areas, including orbitofrontal cortex, parahippocampal cortex, temporal poles, and left hippocampus. These results provide evidence that psychopathic traits manifest similar neural abnormalities across sex and age.

Figure S1 Regional gray matter volumes negatively associated with Psychopathy Checklist-Youth Version (PCL-YV) Total scores, controlling for brain volume, age at scan, and years of regular substance use. All voxels indicated in blue color map represent regions that are significant in the whole brain at p < 0.05 and 1366-voxel extent. Coordinates are in Montreal Neurological Institute (MNI) space. The color bar represents t-values. Significant negative clusters can be found in lateral orbitofrontal cortex, temporal poles, and insula. There were no positive associations for this model.

Figure S3 Panel a: Regional gray matter volumes negatively associated with Psychopathy Checklist-Youth Version (PCL-YV) Factor 1 scores, controlling for brain volume, age at scan, substance dependence, anxiety diagnosis, and Factor 2 scores. Panel b: Regional gray matter volumes negatively associated with PCL-YV Factor 2 scores in females, controlling for brain volume, age at scan, substance dependence, anxiety diagnosis, and Factor 1 scores. These regions are significant in the whole brain at p < 0.05 and 1366-voxel extent. Coordinates are in Montreal Neurological Institute (MNI) space, and the color bar represents t-values.

Figure S4 Substance dependence, brain volume, age, participant sex, PCL-YV Total scores, and a participant sex by PCL-YV Total score interaction term predicted regional gray matter volume, with males and females combined into one sample (N = 230). At p < 0.05 and a 1334-voxel extent, there were no regions significantly associated with the interaction term. This scatterplot illustrates these effects in the left temporal pole, where main effects of participant sex and PCL-YV scores are significant, but the interaction is not. (PNG 58 kb)

Figure S5 Regional gray matter volume differences in male (n = 191) and female (n = 39) adolescents, controlling for brain volume and age at scan. Regions with greater gray matter volume in males are in orange/red. Regions with greater gray matter volume in females are in blue. These regions are significant in the whole brain at p < 0.05 and 1334-voxel extent. Coordinates are in Montreal Neurological Institute (MNI) space. The color bar represents t-values. (PNG 261 kb)
