A dimensional approach of psychopathology focuses on features and risk factors that are shared across diagnoses. In support for this dimensional approach, studies point to a general psychopathology factor (GPF) associated with risk for multiple psychiatric disorders. It is, however, unknown how GPF relates to white matter integrity (WMI). In the current diffusion tensor imaging (DTI) study, we examined how GPF relates to abnormalities in a skeleton representation of white matter tracts, taking into account a trans-diagnostic risk factor: unresolved-disorganized attachment (Ud) resulting from loss or trauma. Unique associations between GPF, Ud, and WMI were examined in a combined sample of adolescents (N = 63) with childhood sexual abuse-related posttraumatic stress disorder (N = 18), anxiety and depressive disorders (N = 26) and without psychiatric disorder (N = 19). WMI was measured using DTI. Ud was measured using the Adult Attachment Interview. We controlled for puberty stage, gender, age, and IQ. Controlling for GPF, Ud was associated with reduced fractional anisotropy (FA) in the splenium and inferior fronto-occipital fasciculus (IFOF). Controlling for Ud, GPF was associated with reduced FA in the genu and body of the corp...Continue Reading
