Does the severity of psychopathological symptoms mediate the relationship between patient personality and therapist response?

Countertransference can be viewed as a source of valuable diagnostic and therapeutic information and plays a crucial role in psychotherapy process and outcome. Some empirical researches have showed that patients' specific personality characteristics tend to evoke distinct patterns of emotional response in clinicians. However, to date there have been no studies examining the impact of patients' symptomatology on the association between their personality and therapists' responses. This research aimed to (a) investigate the relationship between patients' symptom severity and clinicians' emotional responses; and (b) explore the possible mediated effect of symptom severity on the relationship between patients' personality pathology and countertransference responses. A sample of psychiatrists and clinical psychologists (N = 198) of different theoretical orientations completed the Shedler-Westen Assessment Procedure-200 and the Therapist Response Questionnaire on a patient currently in their care, who then completed the Symptom Checklist-90-Revised. The findings showed that patients' symptomatology partially mediates the relationship between their specific personality disorders (in particular, schizotypal, borderline, histrionic, and avoidant) and therapists' emotional responses, but in general, the impact of symptom severity is less sizable than one aroused by patients' personality style. Higher levels of patients' symptom severity are most associated with an intense feeling of being overwhelmed, disorganization, helplessness, and frustration in clinicians. These countertransference reactions are not accounted for by therapists' different therapeutic approaches and other variables (as gender, age, profession, and experience). The clinical implications of these results are addressed. (c) 2015 APA, all rights reserved).
