Findings show mental contamination is linked to childhood trauma and alexithymia in OCD, suggesting further exploration is needed.
Our findings suggest that mental contamination in patients with OCD may be associated with childhood trauma and, in particular, alexithymic features rather than with OCD symptom severity or specific symptom subtypes. Future studies employing longitudinal and experimental designs are recommended to examine the causal nature of the relationships between mental contamination, alexithymia, and childhood trauma.
