Luborsky et al, 1985) • Helpfulness (correlates highly with outcome measures) e.g. “I can already see that I will eventually work out the problems I came to treatment for” • Cooperation e.g. “I feel I am working together with the therapist in a joint effort” Patient’s and therapist’s judgment 7 Zürcher Fachhochschule Measure (4): Interventions Treatment fidelity • Therapist self-rated fidelity for each session by means of a single item measure (0 – 100%) • Example: „My work with this patient today was performed _____ % with the transaction analysis” 8 Zürcher Fachhochschule Measures (4): Interventions Generic interventions: • Directiveness ( =0.80): Interventions with which the therapist structures the session and introduces information or attitudes not previously expressed by the patient • Support (=0.71): empathy, increases trust, enables the acceptance of feelings • Medication (single item): discussions related to the topic of medication 9 Zürcher Fachhochschule Sample • Therapies with at least 15 sessions 10 Zürcher Fachhochschule Sample characteristics Sex: female Age 68% 39.5 (12.5) Axis I (most frequent) affective disorders 30% anxiety disorders 13% both 16% 59% Axis II cluster A (schizoid, etc) 5% cluster B (narcissistic, etc) 17 % cluster C (avoidant, etc) 23 % Axis III (general medical conditions) 11 45% 41 % Zürcher Fachhochschule Severity of symptoms • BDI-Score of patients with affective disorders: mean=22, sd=8 mild to moderate depression • T-score on the anxiety scale (BSI) of patients with anxiety disorders: mean=70, sd=10 12 Zürcher Fachhochschule Data analysis Statistical software R 2.10 Technique Packages Multiple imputation mi Linear mixed models nlme, lme4 Number of observations: 1660 13 Zürcher Fachhochschule Proportion of missing data imputed Motivation Demographic and anamnestic data Axis II diagnosis BSI, BDI Missing proportion 19% 1 – 18% 12 % 4% • Multiple imputation with 3 chains • Longitudinal data was not subject to imputation 14 Zürcher Fachhochschule Results 15 Zürcher Fachhochschule Zürcher Fachhochschule Treatment fidelity Random effects Likelihood ratio Sig (2 ) 13377 320.5 <0.01 Therapist 12531 847.8 <0.01 Patient 12418 114.9 <0.01 Added random effects - 13696 Institute 16 AIC Zürcher Fachhochschule Treatment fidelity Significant fixed effects t value -3.4 sig (MCMC ) <0.01 Alliance (therapist’s judgment) 2.9 <0.01 Psychiatric treatment in the last 2 years -2,7 <0.01 Support 4.3 <0.01 Therapist age 17 Zürcher Fachhochschule Symptom distress Random effects 11702 Institute 11703 0.8 0.36 Therapist 11558 147.3 <0.01 Patient 11070 489.8 <0.01 18 AIC Likelihood ratio Sig (2 ) Added random effects - Zürcher Fachhochschule Symptom distress Significant fixed effects t value 4.4 sig (MCMC ) <0.01 Alliance (patient’s judgment) -6.6 <0.01 Alliance (therapist’s judgment) -4.4 <0.01 Directiveness 2.7 <0.01 Support 2.0 0.04 Medication 2.3 0.02 Anxiety disorder 19 Zürcher Fachhochschule Interpersonal relations Significant fixed effects t value 2.5 sig (MCMC) <0.01 2.3 2.5 0.02 0.01 Motivational congruence -2.9 <0.01 Alliance (patient’s judgment) -7.4 <0.01 Alliance (therapist’s judgment) -2.2 <0.01 Directiveness 3.2 <0.01 Support 2.3 0.02 Anxiety disorder Cluster A (schizoid, etc) Cluster C (avoidant, etc) 20 Zürcher Fachhochschule Clinical significance Congruence between alliance rupture and increase of interpersonal problems increase of interpersonal problems alliance rupture no yes no 140 44 yes 18 (11%) 16 (27%) total 158 (100%) 60 (100%) Relative Risk: 2.3 21 Zürcher Fachhochschule Alliance Significant fixed effects Patient’s judgment as dep. variable Session Motivation for therapy t value -3.8 sig (MCMC) <0.01 3.8 0.02 Therapist’s judgment as dep. variable Session Support 22 t value 2.6 2.8 sig (MCMC) 0.01 <0.01 Zürcher Fachhochschule Summary Psychopathology Working alliance Symptom distress Medication 23 Working alliance motivation Interpersonal relations Treatment fidelity Support Directiveness & Support Zürcher Fachhochschule Thank you for your attention 24 Zürcher Fachhochschule Zürcher Fachhochschule
