Science has served as a powerful tool to elevate the quality of modern addiction treatment, and there is no name more associated with that effort than Dr. Tom McLellan. Dr. McLellan served as Professor of Psychology in Psychiatry at the University of Pennsylvania, developed the Addiction Severity Index, authored more than 400 articles and chapters on addiction treatment, founded the Treatment Research Institute (TRI), and held the position of Editor in Chief of the Journal of Substance Abuse Treatment. He currently leads demand reduction efforts at the White House Office of National Drug Control Policy (ONDCP). His persistent and eloquent voice, challenging the field to fundamentally rethink how addiction treatment is designed and evaluated, has earned him innumerable awards from professional societies in the United States and Europe. In this wide-ranging interview, Dr. McLellan explores his career and what he has learned from his studies about addiction treatment and the role of the addiction counselor in treatment outcomes. He also shares his thoughts about the future of addiction treatment and how he has sought to influence that future through his work at ONDCP. Bill White: Tom, you’ve spent your career wrestling with questions of great relevance to frontline addiction professionals. What circumstances led to your pursuing research on addiction treatment? Bill White: One of your early interests there was the relationship between patients’ drug choices and particular types of psychiatric disorders. How did that interest develop? Because I had interviewed these individuals without any kind of background, I later went and looked up their diagnoses. It turned out that their diagnoses were quite related to the kinds of drugs that they had been using. People who were diagnosed as depressed were often using a variety of depressant or tranquilizing drugs. People who were diagnosed with schizophrenia had histories of using amphetamine—there was very little cocaine use at that time. The people with alcohol and opiate use backgrounds had a variety of diagnoses. I wrote an early paper on this possible relationship. This led me to ask such questions of current patients, many of whom had been coming to the Veteran’s Administration for a number of years. By tracing back their early psychiatric test results, I found over a six year period, in a sample of people who had returned to treatment every year for six years, that there was a progressive development of psychiatric problems that mirrored the actions of the drugs they were using. Particularly interesting were the changes in psychiatric diagnoses among people who used amphetamine/methamphetamine over a six year period. They moved from being treated primarily in the drug unit, to being treated in the psychiatric unit, and finally, into locked wards. It looked as though, after some period of time, the symptoms that were purely drug-related and temporary ultimately ended up being permanent or semi-permanent. The same thing happened with people who used combinations of alcohol and depressants. Depression—significant, serious depression—was sustained. Also interesting, we saw no major changes in the psychiatric problems of people who used opiates or alcohol. As a point of potential interest to young researchers, I wrote these findings and tried to present them to the American Psychological Association, and they turned it down flat. A friend of mine said he thought it had some medical interest, and it was later a lead article in the New England Journal of Medicine. So, for young people who are starting out, don’t get too worried if you get a rejection. The other point of interest is that much of what I’ve learned and done was not achieved through planned studies and experiments, but by being in a clinical situation and keeping my eyes open and listening to the clinicians and especially to the patients. Bill White: That reinforces for our readers the importance of observation and reflecting on those observations. Bill White: Many of our readers at Counselor know you through your work developing the Addiction Severity Index. When you look back over the years since its original development, what are the most important things you have learned about the process of clinical assessment? So being very proud of myself, I showed it to the clinical staff. They didn’t like it one bit, primarily because it was filled with numbers, and the numbers couldn’t really translate into something that they were used to—a nicely written, professional admission note and a treatment plan. So I said, “You don’t want a researcher without a lot of clinical experience doing a treatment plan, so suppose I just summarize the information in each area into a single severity as a single number?” And that’s what I did. I had already named it the Addiction Severity Index because I fully expected that all of the problems—the employment, the legal, the medical, psychiatric, etc.—would be the direct result of the severity of the drug use. Well, I was amazed to find that that was not the case. People with the most severe drug problems often did not necessarily have the most severe employment or psychiatric problems. People with really severe psychiatric problems, for example, often did not have severe drug problems. I had named it an “Index” because I thought we could add up all the numbers into one single number, but that was clearly not possible given what we were finding. But more importantly, it suggested to me from the very beginning that “addiction related problems” can be related in very different ways. Some problems cause substance use; some problems result from substance use; and some simply emerge along with substance use as the result of genetic, personality or environmental conditions. This was one of the most important things I ever learned about addiction. Like many of the people I meet in my current job, I too thought that if you just reduce the drug use, all the other “drug related” problems would disappear. This was, and still is, a very naïve view. Worse, it has been a very big force in the way the original—and some of the existing—treatment programs were conceptualized, designed, funded and evaluated. Bill White: You have challenged the field to make addiction treatment more attractive and engaging. How might addiction professionals working in local treatment programs contribute to that goal? I’ve spent my whole career looking at all of the kinds of things that have been tried—at least in this country—to reduce substance use problems, and treatment is by far the best. So, my whole goal from early on has been to find ways of getting more people into treatment and keeping people who are already in treatment, in treatment longer. With that proviso, let me begin by saying that the nature of most existing addiction treatment has not been particularly attractive to most of the individuals who could benefit most from it. That is not my opinion; that is just simple fact. We have between 23 and 25 million people with diagnosed substance use problems in the country, and on any given day, there’s maybe 2 to 2.5 million of them in treatment. So, only one-tenth of those with a diagnosed illness are receiving care. More importantly, that 10 percent is by no means representative of the rest of the 25 million people. They’re the most severe. They’re the most chronic and difficult. Most of them have been forced into treatment. Further, they’re in treatment that is typically segregated from the rest of healthcare. So I don’t see this as the best way to attract more people into treatment or to keep patients in treatment longer. We have to find ways to make treatment more attractive and effective for this larger population. Bill White: Tom, do you see a day when addiction counselors will be working in a wide variety of settings outside of specialized addiction treatment? Addiction is causing and is complicating a lot of medical disorders. Mainstream healthcare has never really paid the attention it should have to addiction related problems in the mainstream healthcare system. Meanwhile, as addiction treatment has become more segregated, budgets have been reduced virtually every year since I’ve been working in this field. I know of no kind of treatment, education or public enterprise that is best when it is segregated. So we’re trying very hard to bring addiction treatment—particularly screening and early intervention with mild to moderate substance use disorders—into lots more healthcare settings, particularly primary care and family medicine centers. Importantly, I am talking less about “addiction,” than about the less severe and less chronic forms of substance use—unhealthy use, problematic use, etc. We’re trying to develop more and more varied kinds of treatments: treatments that will involve medications, treatments that will involve families; treatments that will involve whole communities. We are hoping that different types of treatments for mild to moderate substance use problems, delivered within the same context as the rest of medical care, are more attractive and engaging to those who will not even consider treatment now. And if you’re wondering if I’m ever going to get around to answering your question, in every one of these environments, there is a need for workforce. Certainly physicians are not going to do this alone. Nurses, counselors, psychologists and social workers are going to be needed. Behavioral health disorders so complicate other health disorders that all of these conditions need to be treated in an integrated fashion. So, we need more counselors and other behavioral health specialists ready to rise to this challenge. Tomorrow’s counselor is going to need to know a lot more about medicine, a lot more about genetics, and a lot more about case management. It will be a quite different role in the coming years. Bill White: One of the questions that you’ve researched that will be of great interest to the readers of Counselor is whether the counselor is an active ingredient in addiction treatment outcomes. Could you summarize what your research revealed on this question? This early finding led to a much more systematic effort. During the rapid expansion of methadone treatment in response to the AIDS epidemic, there was a call for “minimum methadone,” basically methadone alone, without any kind of counseling. This was and remains a well-intentioned effort to get this very potent medication to people who are using street opiates. So we asked, “Is a counselor really necessary?” We did a randomized controlled trial where patients got very minimal counseling—only an admission assessment—and then were brought up to a pretty conventional dose of methadone. A second group got the same methadone at the same dose, but they got regular, standardized counseling using the kind of model that the Johns Hopkins folks have used, developed by Maxine Stitzer. The third group got the same methadone, the same counseling as the second group, but they also got access to lots of social services: employment, psychiatric, medical care. The findings on any measure that you wanted to look at were just like a dose response. Patients who got methadone alone did show improvement, but it was modest; it was minor. Many of them had to be essentially rescued and then received more counseling. The patients who got exactly the same methadone dose plus counseling did much better, and the patients who got the combination of methadone, counseling plus additional social services did the best. In terms of cost-effectiveness, it was methadone plus good solid counseling that was best. So that affirmed for me in both clinical ways and in cost-effective ways that counseling was essential. But the other thing that’s as important to say again is not everybody can be, or ought to be, a counselor. There are protocols to do counseling that can be combined with case management and information management. I’m afraid that not enough counselors are learning counseling as a profession. They’re simply being thrown into it and asked to “do group.” That’s not counseling. Bill White: You’ve spent much of your career assessing the relative effectiveness of addiction treatment. What major conclusions have you drawn from the treatment effectiveness research? There are two conclusions I’ve drawn from all this. One, from a clinical perspective, I think addiction has much to be proud of—but also a long way to go. With far less support, far less organization, but far more use of individuals actively managing their disease (people in recovery), we’ve managed to have roughly the same levels of success and unfortunately, failure as other major illnesses. I think the next steps for our field are to incorporate some of the lessons learned from the management of other chronic illnesses. The second conclusion is that guys like me have been evaluating addiction treatment in the wrong way for a very long time. Because addiction has been segregated, because its origins haven’t been understood, because addiction causes so many social problems, it’s been easy to think of addiction as a moral problem or a sin, and those who are addicted as simply criminals who need to be punished, taught a lesson, all that. God forbid you would have attractive, long-term treatments for that kind of a person. No, you want acute care, short and punitive. Better if they don’t like it. Better if they learn to get discipline and take their medicine. Well, that is not the way you treat other chronic illnesses. It’s not the way you treat illnesses that don’t have a cure, and I don’t think we have a cure for addiction. We’ve had explicitly as our therapeutic goals to get people out of addiction treatment as soon as possible—to get them graduated. The rest of medicine realizes that if you don’t have a cure, the best thing you can possibly do is keep people in treatment. I’m not talking about residential care for the rest of their lives, but keeping them engaged in outpatient treatment for at least a year, perhaps two years, where relapses are anticipated, caught early, and intervened upon directly and therapeutically. That’s one of the most important lessons I have learned. The third and final thing I’ve learned is not only have we been evaluating it the wrong way, the government has been purchasing it the wrong way. The government is not purchasing the kind of sustained, outpatient, continuing, multifaceted care that the evidence shows has the best results. The government spends a lot of money on short-term detoxifications not followed by any other kind of care. That is money wasted. Bill White: You recently collaborated with Deni Carise and Herb Kleber to address the question of whether the current infrastructure of addiction treatment could support the public’s demand for quality treatment. What were your conclusions that you drew from that study? We have brief interventions to intervene early in the development of substance-related problems that are very clinically effective and cost-effective. We’ve got medications for opiate, alcohol, nicotine, some indications for cocaine, not much yet for methamphetamine treatment, but we’ve got good medications. We have many evidence-based therapies that require sophisticated therapists, but that can have enduring benefits. These are not simply my opinions but facts based on two decades of very good research. Well, the average treatment program in this country simply cannot implement most of those treatment ingredients. Most do not have a doctor, so medications are out. Most do not have integrated information systems, and there are government regulations that prohibit exchange of information between addiction treatment and the rest of healthcare, so case management and information management is very difficult. Most treatment programs don’t have a workforce that’s been adequately trained and clinically supervised. Worse, because of contemporary funding constraints, I’m sorry to say I don’t think significant upgrading of training or clinical services is going to happen in these programs, again, in some significant part, because addiction treatment is segregated from the rest of healthcare financially, administratively and in terms of regulations and information. Bill White: One of the issues that has dominated many discussions in this past decade is the whole issue of the gap between clinical research and clinical practice as one dimension of this larger quality of treatment issue. What are your current views on the issues related to that gap between research and practice? While much of the addiction treatment system is segregated from the rest of healthcare, most addiction researchers are very integrated into mainstream academic healthcare settings. So the medications, therapies and other interventions are generally developed in more academic, Bill White: I was really struck by one of your recommendations to enhance the quality of addiction treatment resources. You recommended that addiction treatment be formally declared a distressed industry to bring additional resources to support workforce development. What do you think are some of the most important next steps for workforce development in the field? The labor department, who we’re now working with, is responsible for the training and development of workforces. In the past in this country, the declaration of an area of commerce that has particular importance for our society and has suffered workforce problems (e.g. electronics, alternative energy, farming, etc.) has been associated with an infusion of new money, new training programs, new credentialing and skill development programs all from the Department of Labor. Those kinds of interventions have been responsible for some of the dramatic developments in the electronics and farming industries in this country. I think they ought to be brought to bear in the behavioral health field, particularly addictions. Bill White: I’ve acknowledged the article that you, David Lewis, Charles O’Brien and Herb Kleber published in the Journal of the American Medical They say, “Well, if it’s an illness, it is one brought on by the individual” or “If it is an illness, it’s not a real illness.” They don’t understand that most illnesses in this country, particularly chronic illnesses, are brought on by the behaviors of those who ultimately contract the illness. Adult-onset diabetes, hypertension, asthma, tooth decay, lots of them are brought on by behaviors combined with genetics, and they produce really significant public health conditions that are unambiguously treated in healthcare settings. Perhaps worse, I hear lots of people who are working in the addictions field say the words “addiction is a chronic illness,” but they keep doing the same acute care kinds of treatments and addiction researchers keep evaluating the effects of addiction treatment with 12-month post-treatment outcomes. Insurance coverage for addiction treatment has finally begun to realize—as a result of parity legislation and now through the Healthcare Reform Act—that addiction ought to be managed the same way, in the same kind of an environment, with the same kind of clinical information exchange as other chronic illnesses. Bill White: If we really did treat addiction as a chronic disorder, how would the current role of the addiction counselor change? Recovery-oriented systems of care are starting to emerge in many places as they are now in Philadelphia and the state of Connecticut. As far as I’m concerned, they offer a very nice model for how you should treat other chronic illnesses in a cost-effective manner. With that said, I think people with behavioral health experience—counselors, social workers, family counselors, psychologists—who learn about addiction and learn about the methods to manage it through combinations of medications, family involvement, peer involvement, monitoring and social supports are going to be invaluable, not just to the treatment of addiction, but to the treatment of chronic illness generally. Bill White: It is interesting to me that at this late stage of the field’s development, we are just getting around to defining recovery. You led the effort by the Betty Ford Institute to assemble a consensus panel to create a working definition of recovery. What would you say you’ve learned from that process? First, there is no single way to get into recovery. That was a lesson I learned from you, Bill. The most popular and storied way of getting into recovery is through involvement in a 12 Step program. It remains one of the staples of our field, but it’s not the only way. Second, abstinence is necessary but not sufficient. People who simply don’t drink but continue behaviors and attitudes that are associated with an addiction lifestyle are not going to be abstinent for long as far as I’m concerned. Third, probably more important than anything else, is that recovery is not only achievable, it’s downright expectable. There are, according to the Faces and Voices of Recovery, at least 20 million people today who consider themselves to be in active, stable recovery, and the public at large has no idea about that. Too many think that addiction is a lost cause. They think that there’s no real hope, and unfortunately, it’s because they don’t know that they are quite literally surrounded by people who are in recovery but don’t talk about it every day. This is one of the things that we want to make clear to the public: that recovery is not only possible, it’s expectable, and it should be the goal of every treatment episode. Having a solid, well supported recovery community is a tremendous resource for any community and any family and any individual. Bill White: Were you surprised at the international interest that the Betty Ford Institute recovery definition consensus generated? Bill White: The current call to transform addiction treatment into recovery-oriented systems of care seems clearly an outgrowth of much of your work. Do you see this current focus on long-term recovery as a sustainable movement as we go forward? But I think you are right to emphasize not just recovery but also the recovery system of care. We have always had charismatic individuals who could bring individuals into recovery—wonderful, but not adequate. We need systems that can be created and implemented and managed at the community level that will make recovery an expectable outcome of becoming sober and beginning a new lifestyle. I think it’s going to be one of the most cost-effective kinds of infrastructure development that we will do in this country. As we begin healthcare reform, addiction treatment will be quite dramatically effected. Addiction treatment will be part of the rest of medicine. A very realistic question is what will happen to the federal Block grant? My own view is the federal Block grant ought to remain, and that it ought to be more directed toward building and sustaining recovery-oriented systems of care. As individuals get interventions and initial primary care through the mainstream healthcare system of the future—and that care is reimbursed through Medicaid—they will hopefully get a kind of care that they’ve never had before, but they won’t be cured. What they’ll need is places they can go following that initial Bill White: Many people working in the addictions field draw upon experiential knowledge related to their own personal or family addiction recovery experiences. You have been quite public about how addiction recovery affected your family. How has this experiential knowledge influenced your work in the field? Bill White: On Aug. 10, 2009, you were sworn in as the Deputy Director of the White House Office of National Drug Control Policy. What enticed you to leave the Treatment Research Institute and assume this role? I do know that our Director, Gil Kerlikowske, has really improved the morale and function of ONDCP, and we have unprecedented support and involvement from the Vice President’s office. Day to day, it’s like walking through jello, but I think we have a shot at really helping people in the long run. I miss terribly the puzzles and excitement of investigation and discovery with my friends at my old job. Bill White: Could you talk about how you have tried to influence the future of addiction treatment through this role? Second, I have tried to move addiction integration forward. Despite the pervasiveness of addiction problems, they seem to be hidden under rocks, under rugs and behind doors. And yet, substance use problems affect every part of mainstream society from education to business to healthcare, criminal justice and welfare. Part of my role here has been to help those in policy positions see that they will never get a handle on healthcare reform, prison reform, sentence reform, welfare reform or educational reform if they don’t address substance use issues. My sinister plot for insinuating this issue into mainstream policy is to show them that attention to substance use issues within their own areas will help them develop far better policies and programs—that attention to substance use issues will help them reach their own goals in a much better way. We can add value to the rest of mainstream society. Substance use and addiction as an issue needs to be part of mainstream society, not shoved off to the side. Bill White: You recently announced that you will be leaving ONDCP at the end of September. What factors led to this decision? The first factor in my decision is that I think much of what I can do has been done with the passing of the Parity and the Healthcare Reform Acts. Thanks to the work of many, many people working in and with government, we have an unprecedented future for the substance use prevention, early intervention and treatment fields. That legislation will bring our issue directly into the mainstream of healthcare and while it will not be smooth or easy, addicted people will have opportunities they never have had. While the legislation, regulation and money to bring this came from the hard work of many in the federal government, the actual translation of how these opportunities will emerge will not come from federal government—it will come from the innovation and dedication from public and private groups in our industry. I want to be part of the innovation and creativity that I think will generate from within and outside our field over the next decade. New solutions will be developed by people already in—but also people that are now outside our field. Those ideas and opportunities will be tried at the community level and those that show benefit will become incorporated while old ways and new ones that don’t work will be discarded. I think that is the way it should be and I would like to play some part in those efforts at the grass roots. The second factor is simply that government processes do not suit my personality. I do not like the partisanship and institutional defensiveness that I see in so many places in government. Both these factors combine to turn issues where there is an empirical answer into a political or populous decision. The answer to “What does 2 + 2 equal?” does not take a committee or a vote; and regardless of public support or outcry—it is simply the correct answer. Researchers spend their lives looking for correct answers and I like industries and environments that foster that process. Bill White: There is considerable interest in what activities you will pursue after leaving ONDCP. What are your immediate post-ONDCP plans? Bill White: Are there any final messages you would want to convey to frontline addiction professionals across the United States?
