- Abstract
Background/Objective: A detrimental impact of narcissistic personality traits on depressive symptomatology, therapeutic alliance, and treatment outcome, even in the absence of narcissistic personality disorder (NPD), has been theorized. However, the evidence base in clinical settings is lacking. As research classification systems such as the ICD-11 and DSM-5 are moving towards a dimensional operationalization of personality disorders, it appears imperative to examine narcissism as a multifaceted construct and its impact on depressive symptom severity across mental disorders and different treatment settings. Moreover, due to the common interpersonal challenges associated with narcissism, the therapeutic alliance might be a key mechanism to understand narcissism related poorer treatment response.Methods: We examined the effect of narcissism and its facets admiration and rivalry on baseline as well as post-treatment depressive symptoms in two independent samples: one sample from a cognitive behavioral treatment setting, pooled from an inpatient psychiatric clinic and a cooperating outpatient treatment service (CBT; n = 1569) and an inpatient clinic with psychodynamic treatment focus (PIT; n = 802). An additional mediation analysis for the effect of the therapeutic alliance on the association between narcissism and depression severity after treatment was conducted in the outpatient CBT subsample.Results: Narcissistic rivalry was associated with higher depressive symptom load at baseline, while narcissistic admiration showed the opposite effect in both samples. Core narcissism was not related to depression severity before treatment. Poorer treatment response was predicted by core narcissism and narcissistic rivalry in the CBT sample while no effect of narcissism on treatment outcome was discernible in the PIT sample. Therapeutic alliance mediated the effect of narcissism on post-treatment depression severity in the outpatient CBT sample.Conclusions: As narcissism affects depression severity before and after treatment across psychiatric disorders even in the absence of NPD, the inclusion of dimensional assessments of narcissism should be considered in future research and clinical routine. Building on this, the observed relevance of the therapeutic alliance and the therapeutic strategy might be leveraged to guide personalized treatment approaches.
