Common versus Specific Factors and the Future of Psychotherapy: A Response to Siev and Chambless

October 31, 2009 By scottdm 4 Comments

Early last summer, I received an email from my long time friend and colleague Don Meichenbaum alerting me to an article published in the April 2009 edition of the Behavior Therapist–the official “newsletter” of the Association for Behavioral and Cognitive Therapies–critical of the work that I and others have done on the common factors.

Briefly, the article, written by two proponents of the “specific treatments for specific disorders” approach to “evidence-based practice” in psychology, argued that the common factors position–the idea that the efficacy of psychotherapy is largely due to shared rather than unique or model-specific factors–was growing in popularity despite being based on “fallacious reasoning” and a misinterpretation of the research.

Although the article claimed to provide an update on research bearing directly on the validity of the “dodo verdict”–the idea that all treatment approaches work equally well–it simply repeated old criticisms and ignored contradictory, and at times, vast evidence. Said another way, rather than seizing the opportunity they were given to educate clinicians and address the complex issues involved in questions surrounding evidence-based practice, Siev and Chambless instead wrote to “shore up the faithful.” “Do not doubt,” authors Siev and Chambless were counseling their adherents, “science is on our side.”

That differences and tensions exist in the interpretation of the evidence is clear and important. At the same time, more should be expected from those who lead the field. You read the articles and decide. The issues at stake are critical to the future of psychotherapy. As I will blog about next week, there are forces at work in the United States and abroad that are currently working to limit the types of approaches clinicians can employ when working with clients. While well-intentioned, available evidence indicates they are horribly misguided. Once again, the question clinicians and consumers face is not “which treatment is best for that problem,” but rather “which approach “fits with, engages, and helps” the particular consumer at this moment in time?”

Outcomes in Ohio: The Ohio Council of Behavioral Health & Family Service Providers

October 30, 2009 By scottdm Leave a Comment

Ohio is experiencing the same challenges faced by other states when it comes to behavioral health services: staff and financial cutbacks, increasing oversight and regulation, rising caseloads, unrelenting paperwork, and demands for accountability. Into the breach, the Ohio Council of Behavioral Health & Family Service Providers organized their 30th annual conference, focused entirely on helping their members meet the challenges and provide the most effective services possible.

On Tuesday, I presented a plenary address summarizing 40 years of research on “What Works” in clinical practice as well as strategies for documenting and improving retention and outcome of behavioral health services. What can I say? It was a real pleasure working with the 200+ clinicians, administrators, payers, and business executives in attendance. Members of OCBHFSP truly live up to their stated mission of, “improving the health of Ohio’s communities and the well-being of Ohio’s families by promoting effective, efficient, and sufficient behavioral health and family services through member excellence and family advocacy.”

For a variety of reasons, the State of Ohio has recently abandoned the outcome measure that had been in use for a number of years. In my opinion, this is a “good news/bad news” situation. The good news is that the scale that was being used was neither feasible or clinically useful. The bad news, at least at this point in time, is that state officials opted for no measure rather than another valid, reliable, and feasible outcome tool. This does not mean that agencies and providers are not interested in outcome. Indeed, as I will soon blog about, a number of clinics and therapists in Ohio are using the Outcome and Session Rating Scales to inform and improve service delivery. At the conference, John Blair and Jonathon Glassman from Myoutcomes.com demonstrated the web-based system for administering, scoring, and interpreting the scales to many attendees. I caught up with them both in the hall outside the exhibit room.

Anyway, thanks go to the members and directors of OCBHFSP for inviting me to present at the conference. I look forward to working with you in the future.

Whoa Nellie! A 25 Million Dollar Study of Treatments for PTSD

October 27, 2009 By scottdm 1 Comment

I have in my hand a frayed and yellowed copy of observations once made by a well known trainer of horses. The trainer’s simple message for leading a productive and successful professional life was, “If the horse you’re riding dies, get off.”

You would think the advice straightforward enough for all to understand and benefit. And yet, the trainer pointed out, “many professionals don’t always follow it.” Instead, they choose from an array of alternatives, including:

Buying a strong whip
Switching riders
Moving the dead horse to a new location
Riding the dead horse for longer periods of time
Saying things like, “This is the way we’ve always ridden the horse.”
Appointing a committee to study the horse
Arranging to visit other sites where they ride dead horses more efficiently
Increasing the standards for riding dead horses
Creating a test for measuring our riding ability
Complaining about how the state of the horse the days
Coming up with new styles of riding
Blaming the horse’s parents as the problem is often in the breeding.

When it comes to the treatment of post traumatic stress disorder, it appears the Department of Defense is applying all of the above. Recently, the DoD awarded the largest grant ever awarded to “discover the best treatments for combat-related post-traumatic stress disorder” (APA Monitor). Beneficiaries of the award were naturally ecstatic, stating “The DoD has never put this amount of money to this before.”

Missing from the announcements was any mention of research which clearly shows no difference in outcome between approaches intended to be therapeutic—including, the two approaches chosen for comparison in the DoD study! In June 2008, researchers Benish, Imel, and Wampold, conducted a meta-analysis of all studies in which two or more treatment approaches were directly compared. The authors conclude, “Given the lack of differential efficacy between treatments, it seems scientifically questionable to recommend one particular treatment over others that appear to be of comparable effectiveness. . . .keeping patients in treatment would appear to be more important in achieving desired outcomes than would prescribing a particular type of psychotherapy” (p. 755).

Ah yes, the horse is dead, but proponents of “specific treatments for specific disorders” ride on. You can hear their rallying cry, “we will find a more efficient and effective way to ride this dead horse!” My advice? Simple: let’s get off this dead horse. There are any number of effective treatments for PTSD. The challenge is decidedly not figuring out which one is best for all but rather “what works” for the individual. In these recessionary times, I can think of far better ways to spend 25 million than on another “horse race” between competing therapeutic approaches. Evidence based methods exist for assessing and adjusting both the “fit and effect” of clinical services—the methods described, for instance, in the scholarly publications sections of my website. Such methods have been found to improve both outcome and retention by as much as 65%. What will happen? Though I’m hopeful, I must say that the temptation to stay on the horse you chose at the outset of the race is a strong one.
