Objective: Psychotherapists differ notably in the outcomes their patients achieve, and the characteristics that may explain these differences have attracted increasing interest. We systematically review studies on therapist pre-treatment characteristics predicting patient outcomes. Method: Systematic searches on databases for psychotherapy research, clinical psychology, and medical science for the years 2000–2018 identified published research examining therapist characteristics and psychotherapy outcomes. Of 2041 studies, 31 met inclusion criteria. Results: Findings show a few direct effects of therapist intrapersonal variables (e.g., self-relatedness, attachment) and several interaction effects with other constructs (e.g., patient pathology) on outcome. There is little support for the relevance of self-rated social skills. However, more consistent evidence has recently emerged for performance-based measurements of professional interpersonal skills, especially when elicited in challenging situations. Patient outcomes were also predicted by therapists’ self-rated professional characteristics, such as their experienced difficulties in practice, coping mechanisms, and attitudes towards therapeutic work, indicating that therapist self-perception also matters, although not always in the direction expected. Conclusions: More effective therapists seem characterized by professionally cultivated interpersonal capacities, which are likely rooted in their personal lives and attachment history. Research guidelines are proposed for moving this field forward (including larger samples, multilevel modeling, and in-depth qualitative work).

Objective: Interpersonal problems may lead to, uphold, or follow from depression. However, we know little of how depressed patients’ different interpersonal problems are associated with patients’ emotional processing during psychotherapy and whether distinct processes are helpful for their long-term reduction. Method: 23 adult outpatients who received emotion-focused therapies lasting 16–20 sessions filled the Inventory of Interpersonal Problems at pre- and post-treatment and 18-month follow-up. These problems were related to emotional processing in two mid-therapy sessions, rated by observers with the Classification of Affective-Meaning States. Results: All pre-treatment interpersonal problems were clearly associated with patients’ negative evaluations of themselves during therapy. Self-experiences of vindictiveness were most pronouncedly linked to in-session emotional expressions of rejecting anger, and self-experiences of social inhibition to expressions of fear and shame, following a circumplex model. In the long-term reduction of interpersonal problems, especially reaching emotional states of hurt and grief seemed beneficial for patients who experienced themselves as socially inhibited, non-assertive, self-sacrificing, or overly accommodating. Conclusions: For clients suffering from particular interpersonal problems, accessing particularly beneficial emotional processes, such as hurt and grief, may form specific therapeutic process goals. Further studies should verify these findings, which link interpersonal theory with research on emotional processing in psychotherapy.
