Associations between therapists' verbal techniques and patient-rated therapeutic alliance, insight, and problem solving.

OBJECTIVE: To investigate associations between common factors (alliance, insight, problem solving) and therapists' techniques. We expected a positive association between (1) supportive techniques and the alliance, (2) interpretative techniques and insight, and (3) a stronger association between interpretative techniques and insight for patients with more severe baseline symptoms. Other associations were analyzed in an exploratory way.

METHOD: Sixty sessions from 15 adult female patients diagnosed with personality disorder were analyzed using the Psychodynamic Interventions List (verbal techniques, observer-rated transcripts), and the Session Questionnaire for General and Differential Individual Psychotherapy (common factors, patient-rated after each session). Multilevel modeling was applied.

RESULTS: A greater use of supportive techniques was related to a higher therapeutic alliance ( b  = .28, 95% CI : .01-.55, p  = .042). Neither the positive association between interpretative techniques and insight nor the moderating effect of baseline symptom severity could be confirmed. Exploratory analyses revealed associations between problem-solving and different verbal techniques.

CONCLUSION: Therapists' use of supportive techniques seems to influence the therapeutic alliance positively in patients with personality disorders. The effect of interpretative techniques might depend on other factors like patient characteristics. In general, there seem to be differential and specific associations between different therapists' verbal techniques and common factors.
