Investigating the relationship between depression severity and cognitive rigidity through the use of cognitive errors

Aim.This study examined the association between depression severity and an indicator of the diversity of cognitive errors (CEs) used by individuals with major depressive disorder (MDD). Methods. One early and one late therapy sessions for 42 patients were taken from the Jacobson et al. [1, 2] study, transcribed and rated for cognitive errors. Results. Results revealed that the level of diversity of CEs is not significantly associated with depression severity. Discussion. While previous studies [3] have shown that cognitive inflexibility is associated with psychopathology, our findings suggest that rigidity in the CEs used by depressed individuals is not.
