1 Roles of Common Factors & Therapist Effects in Therapy Outcomes Session #0931 G.S. (Jeb) Brown, Ph.D. Center for Clinical Informatics

2 Common factors The effectiveness of all treatments is due, in some part, to factors common to all treatments. Contact with a helping, caring professional fosters hope and expectancy. We have come to accept the potency of placebo effects, and insist that the effectiveness bona fide treatments exceeds that of placebo treatments So far, so good. Who can argue with this?

3 Randomized double-blind placebo controlled drug trials Double blind placebo controlled drug studies provide an exemplar for estimating the role of common factors. Traditionally, the drug is interpreted as the difference between placebo and the active drug. Meta-analysis of multiple studies of antidepressants lets us estimate the relative importance of common factors (placebo effects) versus drug effects.

4 Meta-analyses and placebo Meta-analysis involves the use of a statistical techniques to combine results from multiple studies in order in an effort to generalize findings. Meta-analysis of multiple studies of antidepressants let us estimate the relative importance of common factors (placebo effects) versus drug effects. 1-3

5 Drug effect accounted for 25% of measured improvement Antidepressant effect (25%) Placebo effect Natural course of the illness

6 Evidenced based psychotherapy For several decades psychotherapy researchers have attempted to design randomly controlled trails (RCT) to investigate the effectiveness of specific methods of psychotherapy. Study design analogous to pharmacy trials, except that designing credible placebo treatments is much more problematic. Various treatment methods are being touted as evidenced based by citing the number of RCTs providing evidence that the treatment exceeded placebo (or some other treatment).

7 Psychotherapy brands The advocacy for the use of specific therapies is analogous to the advertising of brands of antidepressant medication. Calls for wide spread use of evidence based treatments in psychotherapy is analogous to the FDA s insistence that a drug may not be marketed for the treatment of depression until at least two studies have shown superiority to placebo. Advocates and practitioners of various evidence based treatments have a vested interest in discouraging the use of unproven treatments.

8 Brand differentiation Advocates of psychotherapy brands insist on the uniqueness of their therapy and the need to adhere to specific treatment procedures Research methodology requires the use of manuals and other techniques to standardize treatments Treatment effectiveness presumed to be dependent on the correct application of the active ingredients in the psychotherapy method.

9 The Dodo Bird Effect Rosenzweig S. (1936) Some implicit common factors in diverse methods of psychotherapy: At last the Dodo said, Everybody has won and all must have prizes. Am J Orthopsychiatry 6:412-5.

10 The Dodo Bird Lives! Wampold BE, Mondin GW, Moody M, et al. (1997). A meta-analysis of outcome studies comparing bona fide psychotherapies: Empirically, All must have prizes. Psychol Bull 122: Luborsky, L., Rosenthal, R., Diguer, L., et al The dodo bird verdict is alive and well--mostly. J. Psychotherapy Integration Vol 12(1) 32-57

11 Meta-analysis & common factors Over two decades of meta-analytic studies have served to reinforce Rosenzweig s 1936 observation that different methods of psychotherapy tend to produce comparable outcomes the Dodo Bird Effect Lack of evidence for specific treatment effects bolster the argument that almost all of the effects of psychotherapy are due to factors common to all psychotherapies. 5-11

12 Real world example Human Affairs International (HAI) collected outcome data from a large number of clinicians between 1996 and Clinicians were asked to specify the primary method of psychotherapy (or medication management only) Analyses revealed no significant differences in the outcome or mean number of sessions across all treatment methods, including medication management.

13 Treatment & outcome HAI data 0.40 Mean Value of Residual Change after Controlling for Severity (positive values = greater than average change; 90% confidence interval) Residual Effect Size Insight Oriented (n=135) Solution Focused (n=647) Behavioral (n=67) Cognitive Behavioral (n=1226) Fam ily (n=152) Medication Management (n=514) Other (n=129) Unknown (n=85) -0.20

14 Fidelity and practicality Propagation of evidenced based treatment methods requires some method of measuring fidelity to the treatment. BIG PROBLEM! If clinicians reports using Cognitive Behavioral Therapy, how can we have any confidence that what that clinician did with a specific patient was comparable to the Cognitive Behavioral Therapy in the RCTs?

15 Goldilocks Effect Clinicians tend to be eclectic and flexible in their choice of treatment methods. Clinicians and patients tend to try different treatments until they find something that is just about right for them. Patients and clinicians tend to adjust the number and frequency of sessions depending on the patient s level of distress and rate of improvement. Result: All treatments appear to have similar outcomes and patients with good outcomes tend to use fewer session than patients with poor outcomes.

16 Recommended reading Rigorous review and analyses of controlled studies on psychotherapy outcome. Conclusion: much more variance resides with the clinician than with the treatments.

17 Therapists effects Wampold and others argue that researchers have ignored the individual therapist as a source of variance. 11, The person of the therapist is necessary to delivery the treatment, and personal characteristics of the therapist modify the effect of the treatment. Factors contributing to therapists effects may include elements clinical skill and knowledge as well as personality traits.

18 RCT and ANOVA brief history Some of the earliest applications of randomized control group design and analysis of variance were in agriculture and education. 12,13 RCT methodology later adopted by medicine and eventually psychotherapy research. 11,14 Simple ANOVA is appropriate only if the individual farmer, teacher or clinician has little or no impact on the effectiveness of the farming, teaching or treatment method!

19 HLM & therapist effects Hierarchical Linear Modeling (HLM) is an advance in statistical methodology that permits us to model variance at the clinicians level and as well as the treatment level. An rapidly growing body of published research points to the conclusion that therapist effects almost certainly exceed specific treatment effects by a large margin.

20 Variance due to the clinician Published research making use of HLM points to the conclusion that the clinician accounts for much more of the variance in psychotherapy outcomes that treatment method per se. 11, Analyses of PacifiCare Behavioral Health s massive database database on patient outcomes confirms significant variance in psychotherapy outcomes at the clinician level. 24,25

21 PacifiCare Behavioral Health ALERT System Initiated an outcomes management program in 1998 using 30 item patient self report questionnaires administered at regular intervals in treatment. ALERT System used to capture data and monitor patient outcomes in real time. Currently over 7,000 clinicians are contributing outcome data on a regular basis. Probably largest database on mental health outcomes in the world.

22 PBH research collaboration PBH actively sought the involvement of leading psychotherapy outcomes researchers from leading academic institutions. External researchers actively involved in design of the measurement system and ongoing analysis of the data. PBH encouraged publication of findings in academic journals.

23 The (almost) Bell Curve PBH data Solo clinicians with sample sizes => 20 25% % of clinicians 20% 15% 10% 5% 0% Effect Size

24 Where is the variance? Unexplained 74% (external stressors, health condition, social supports, etc.) Acuity (intake score) 18% Diagnosis, age & sex 2% Clinicians & treatments Clinician 6% Treatment method 1%

25 % of variance due to therapists in the real world Analysis of PacifiCare Behavioral Health (PBH) data reveals 6% of variance due to therapist. 25 Patients on medication have a higher % of variance due the therapist than those receiving psychotherapy alone. Huh??

26 Therapists and meds Outcomes (residualized scores) of 15 therapists for patients with concurrent medication or no medication meds nom eds

27 Test scores and medication PBH data Percentage of cases on medication as a function of intake score 80% 70% 60% 50% 40% 30% 20% 10% 0%

28 Which treatment is best? Goldilocks Effect: Clients tend to get the treatment that is just about right for them. Treatment, severity and outcome 2.00 Effect size Psychotherapy only Psychotherapy and medication Normal functioning Intake score Severe symptoms

29 Cross validation analysis Psychotherapists in PBH network ranked based on all cases from if sample size =>30; N=116. If a therapist s mean residualized final score < 0 then clinician rated Highly effective ; else clinician rated Less effective. Outcomes evaluated in the cross validation period for a new sample of cases.

30 Cross validation results Effect size Clinician cross validation results to 2004 Therapists assessed on at least 30 cases between Highly effective clinicians had mean Change Index Score > Intake scores (mean split) Highly effective clinicianspsychotherapy only Highly effective clinicianspsychotherapy and medication Less effective clinicianspsychotherapy only Less effective clinicianspsychotherapy and medication

31 Risk of not using HLM Wampold and colleagues at the University of Wisconsin recently reanalyzed data from the National Institute of Mental Health s Treatment of Depression Collaborative Research Program (TDCRP) study using HLM Prior published reports found significant differences between two methods of psychotherapy as well as between placebo and antidepressant medication. Reanalysis of psychotherapy data using HLM revealed that 0% of the variance was due to the psychotherapy methods, while 8% was attributable to the therapists. 27

32 Psychiatrist effects Wampold and colleagues also used HLM to reanalyze the results antidepressant and placebo legs of the TDCRP study. 28 Included the 9 individual psychiatrists as a variable. Outcome measured by change on patient self report measure (Beck Depression Inventory). 9.1% of the variance due to the psychiatrist; only 3.4% due to the medication. Top third of psychiatrists achieved a better outcome with placebo than bottom third achieved with the antidepressant.

33 Placebo & therapist effects Hypothesis: Placebo/common factor effects are mediated by the clinician/patient relationship. Common factors tend to account for much more of the variance than specific treatment effects. If the effects of common factors are mediated by the clinician/patient relationship, then we would naturally find much of the variance in outcomes would be due to the clinician. The human factor matters! DUH!

34 What s a clinician to do? If a wide variety of treatments appear to be equally efficacious, can a therapist do to achieve the best outcomes possible for their patients? A growing body of research supports the use of repeated administrations of patient self report outcome questionnaires to monitor response to treatment. Routine measurement and and early identification of patients with a poor response to treatment has been shown to reduce treatment failures

35 Therapeutic alliance A large body of evidence suggests that the relationship and working alliance between the clinicians and patient is an important factor in the outcome Routine use of a session rating/therapeutic alliance scale may permit clinicians to identify and repair problems in the working alliance.

36 Outcomes informed care Meta-method designed to improve outcomes across all patients and diagnoses, regardless of treatment method. Routine use of patient self report questionnaires to track symptom severity and therapeutic alliance. Use of feedback mechanisms to alert clinicians to patients at risk for poor outcomes. Performance feedback to clinicians, including comparison to outcomes to those of clinicians treating similar patients. Preferential referrals to highly effective clinicians.

37 2 case studies Resources for Living (RFL) provides telephonic EAP services. Customers include Walmart. Accountable Behavioral Healthcare Alliance (ABHA) is a managed behavioral healthcare organization servicing Oregon Health Plan members in 5 rural county area

38 Case history # 1: RFL Began using the 4 item Outcome Rating and Session Rating Scales in 2002 Administered over the phone as part of telephonic counseling sessions.

42 Implications for clinicians Good news: The clinician matters!!!!!! All treatments (including medications!?) are only as effective as the clinicians delivering the treatment. Clinicians have an ethical responsibility to assess and improve their personal effectiveness as clinicians they cannot rely on the treatments alone to be curative. Effective clinicians deliver high value services and are worth more money!!!

43 Implications for administrators & policy makers Exclusive focus on the effectiveness of treatments rather than the value of the clinicians limits the potential to improve outcomes. Use of effective clinicians tends to lower costs. Administrators and policy makers have an obligation to consumers to assure that they have access to effective clinicians. Failure to monitor outcomes at the clinician level places consumers at risk.
