The negative effect of alexithymia on the outcome of group therapy for complicated grief: what role might the therapist play?

Abstract

Alexithymia is a patient characteristic that reflects deficits in the cognitive processing and regulation of emotions. It is generally considered to have an adverse effect on the outcome of psychotherapy. Little is known about the processes through which alexithymia exerts this effect. One proposed mechanism suggests that patients with alexithymia trigger negative therapist reactions that contribute to poor outcome for such patients. This study examined whether therapist reactions to a patient mediate the relationship between alexithymia and outcome in group psychotherapy for complicated grief. Alexithymia was assessed with the Toronto Alexithymia Scale-20. Therapist reactions to a patient, reflecting the therapist's perceptions of a patient's positive qualities, personal compatibility, and significance as a group member, were assessed with a cohesion questionnaire. Outcome in several areas of functioning was measured. We found that alexithymia (specifically, greater difficulty in communicating feelings and greater tendency to engage in externally oriented thinking) was associated with less favorable outcome and that this relationship was mediated by therapist reactions to a patient. The mediation provided by therapist reactions to a patient accounted for approximately one third to one half of the direct effect of alexithymia on psychotherapy outcome. This suggests that therapist reactions to a patient represent a major mechanism through which alexithymia exerts its effect.
