Personality disorder traits, maladaptive schemas, modes and coping styles in participants with complex dissociative disorders, borderline personality disorder and avoidant personality disorder

Abstract

AbstractObjectiveThe schema mode model offers a new conceptualisation of complex dissociative disorders (CDD) as it explains shifts between identities as shifts between schema modes. Furthermore, in this model CDD is conceived as personality pathology, incorporating core features of personality disorders. This study tested the assumptions of this schema mode model of CDD.MethodQuestionnaires measuring personality disorder traits, schemas, schema modes and coping styles were filled out by patients with CDD, borderline personality disorder and avoidant personality disorder (N = 210), and their scores on the various constructs were compared.ResultsParticipants with CDD were characterised by specific schizoid, schizotypal, borderline and avoidant personality traits and early maladaptive schemas in the domains of disconnection and rejection and over‐vigilance and inhibition. The most pronounced schema modes were the dysfunctional parent modes, avoidant coping modes and the vulnerable child mode. For coping styles, no differences were found between the diagnostic groups.Conclusion and discussionOn all outcome measures participants with CDD scored at the level of personality disorders and showed a unique pattern different from participants with borderline and avoidant personality disorder. This suggests that CDD shows features akin to a personality disorder. A clinical implication is that an adapted form of schema therapy might present a viable treatment option for CDD.
