Welcome to my professional blog. I am a Florida Licensed Psychologist and trained scientist-practitioner. In 2008, I received my Ph.D. in clinical psychology. A major component of my professional identity is staying informed about recent developments in the field so that I may provide my clients with scientifically sound information and evidence-based treatment. There is a plethora of information on the internet about Eating Disorders, Depression, Anxiety, Psychotherapy. Unfortunately, much of this information is unsubstantiated and some of it is patently false. It is my hope that by sharing my thoughts and opinions on psychological issues, with scientific research and clinical experience sprinkled in for good measure, I can help to bridge the gap between research and treatment.

Effective Treatment for Bulimia Nervosa: A Good Start

A randomized controlled trial recently published in the American Journal of Psychiatry found that Enhanced Cognitive Behavioral Therapy (CBT-E) was far more effective than psychoanalytic therapy in the treatment of Bulimia Nervosa (BN).

In this study, 70 adults with BN were randomly assigned to either the CBT-E group or the psychoanalytic therapy group. Those in the CBT-E group received 20 sessions over the course of 5 months, whereas those in the psychoanalytic therapy group received weekly sessions for 2 years.

CBT-E for bulimia nervosa directly targets bulimic symptoms of dietary restriction, binge eating, and purging by modifying self-defeating behaviors, identifying and challenging distorted thoughts and beliefs about food, body shape, and weight, and learning skills to regulate moods and deal with setbacks. For example, patients learn to moderate their food intake by consuming regular, satisfying meals and snacks throughout the day rather than fasting, which often leads to nighttime binges.

In contrast, psychoanalytic therapy helps patients work through emotions and resolve inner conflicts which are believed to be at the root of their eating disorder.

After five months of treatment, 42% of patients receiving CBT-E had stopped bingeing and purging, compared to only 6% of patients in the psychoanalytic therapy group. After two years, 44% of patients in the CBT-E group had remained abstinent from bingeing and purging, compared to 15% of patients in the psychoanalytic group. It is important to note that the 2-year assessment represents a 19-month post-treatment follow-up for patients in the CBT-E group, but an end-of-treatment assessment for the psychoanalytic therapy group. Thus, patients in the CBT-E group had maintained their remission 19 months after treatment ended.

I draw the following conclusions from this study:

1.) Treatments which directly target bulimic symptoms are likely to be much more effective than treatments that deal with underlying emotions and psychic conflicts.

2.) Bulimic patients who receive CBT-E experience symptom relief much more quickly than those who receive psychoanalytic therapy.

3.) CBT-E is more efficient and cost-effective. If a psychologist charges $150 per hour, twenty sessions of CBT-E over the course of 5 months would cost a total of $3000. Weekly psychoanalytic sessions for two years would cost a total of $15,600.

4.) The benefits of CBT-E are long-lasting for those who recover

5.) Psychoanalytic therapy can be effective for a small fraction of bulimic patients

6.) CBT-E should be a front-line treatment for bulimia nervosa because, statistically, patients are much more likely to benefit from it than from other treatment approaches.

Bulimia nervosa wreaks havoc on the brain as well as the rest of the body. Insufficient or erratic nutrition caused by restrictive dieting, fasting, bingeing, laxative abuse, purging, and dehydration have a direct and immediate impact on brain function. I suspect that a primary reason for the superiority of CBT-E is that it targets the symptoms of dieting, bingeing, and purging immediately, thereby helping patients achieve medical stability and brain healing. When a person is receiving consistent balanced nutrition and keeping it down, he or she is better able to process emotions, refrain from impulsive behaviors, and do the hard work that is necessary for full recovery.

Perhaps patients in the psychoanalytic therapy group did not have the tools necessary to recover. It is one thing to gain insight into one’s emotions and beliefs; it is another thing entirely to halt a destructive and addictive cycle of restricting, bingeing, and purging.

The authors of this study conclude that it “provides one of the clearest examples of the superiority of one well-implemented psychological treatment over another.” However, CBT-E is not a magic bullet: more than half of the patients who received CBT-E did not recover. Therefore, we need to improve existing treatments for BN and develop new, more effective treatments for this devastating illness.

Expanding Our Minds: Towards a Biologically-Based Understanding of Eating Disorders

I read the abstract of a recently published journal article which illustrates one of the major problems in the field of mental health treatment in general, and eating disorder treatment in particular. The article, authored by Jim Harris and Ashton Steele and published in the latest issue of Eating Disorders: The Journal of Treatment and Prevention is provocatively titled Have We Lost Our Minds? The Siren Song of Reductionism in Eating Disorder Research and Theory.

The authors state that, over the past decade, “the focus of eating disorder research has shifted from the mind to the brain.” I disagree with this assertion on two levels. First, the statement implies that the mind and the brain are separate entities. They are not. The “mind” is simply a range of conscious functions which are carried out by the brain: for example, thoughts, beliefs, emotions, intentions, motivations, and behaviors. These mental functions originate in the brain, are executed in the brain, and are interpreted by the brain.

Indeed, recent developments in genetics and neuroimaging techniques have allowed scientists to study the structure, function, and circuitry of the brain in far greater detail than was possible before. Researchers have utilized this new technology to generate and test novel hypothesis about the biological underpinnings of eating disorders. The results of these studies have indicated that eating disorders are genetically inherited, biologically-based brain disorders, similar to bipolar disorder and schizophrenia.

However, while research in the area of genetics and neuroimaging has proliferated in the eating disorders field, there has been no shortage of research on psychosocial factors or non-medical treatments for eating disorders, such as FBT and DBT. Contrary to Harris and Steele’s assertion, we have not “lost our minds.” We’ve simply expanded our minds and deepened our realm of investigation to study the biological underpinnings of mental functions as new technology has allowed us to do so.

Harris and Steele assert that the brain disorder model of eating disorders necessitates that treatment targets the underlying neurobiological abnormality; namely, medication. The authors then conclude that the brain disorder model of eating disorders is misguided because no pharmacological intervention has been shown to significantly benefit patients with anorexia nervosa.

This simplistic assumption and its corollary reflect a lack of basic understanding of the relationship between the brain and the symptoms of psychiatric illness. The authors fail to recognize the fact that certain non-medical interventions HAVE been consistently shown to benefit patients with biologically-based brain illnesses.

For example, it is widely accepted amongst medical and psychological professionals, as well as the general public, that autism is a biologically-based brain illness. There are no medications which have shown to consistently benefit children with autism. The gold-standard of treatment for autism is early intervention with applied behavior analysis (ABA), which is a form of behavior therapy focused on skills building, parent training, and modifying environmental contingencies. Most children with autism do extremely well with this type of treatment, and many of them can be mainstreamed in classrooms with typically developing children.

Sound familiar? It should, because that is precisely what is happening in the world of eating disorder treatment. The treatment approaches which have shown the most promise in the world of eating disorders are psychological and behavioral treatments such as Family-Based Treatment (FBT) for anorexia nervosa and Cognitive-Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT) for bulimia nervosa.

There are a number of misconceptions about these types of treatments. For example, many people believe that FBT is merely re-feeding. This is not so. FBT is a psychological and behavioral treatment – a form of psychotherapy – and parental control of re-feeding is but one component of the first phase of this three-phase treatment model.

As another example, some people believe that CBT and DBT are merely “learning skills.” Again, this is a misconception. CBT and DBT are forms of psychotherapy which involve a relationship with a therapist who instills hope, provides support and feedback and accountability, promotes awareness of thoughts and feelings, and teaches adaptive skills for managing life’s challenges.

Contrary to popular belief, psychotherapy does not consist of lying on a couch and talking about your mother. That myth stems from psychoanalysis, an antiquated form of treatment commonly practiced in the mid-20th century which has no evidence base. Modern evidence-based psychotherapy is entirely different: it is active, directive, and believe it or not, effective.

I get a bit irritated when uninformed people make sweeping generalizations on either side of the fence, such as “psychotherapy doesn’t work for eating disorders,” or, on the flip side, “psychotherapy is the best way to treat eating disorders.” The truth is more specific: evidence-based psychotherapies are effective in the treatment of eating disorders.

From my perspective, focusing on the biological basis of psychiatric illnesses does NOT mean:

• That the illness can only be treated with a pill
• That psychological and social factors are irrelevant
• That environment doesn’t matter
• That the patient can’t do anything about it
• That the psychologist’s job is obsolete

Focusing on the biological basis of eating disorders DOES mean:

• That eating disorders are illnesses, no different from cancer or diabetes or schizophrenia
• That patients do not, and in fact cannot, choose to develop eating disorders
• That eating disorders are not caused by family dynamics or social pressures
• That prevention efforts aimed at improving body image are unlikely to be effective
• That a person must have a certain genetic predisposition in order to get an eating disorder
• That biological relatives of eating disorder patients are at risk for developing the disorder themselves
• That medication can be helpful, though not curative, in some cases
• That full nutritional restoration, and thereby correcting the brain-based symptoms of starvation, is a necessary first step in treatment
• That psychotherapy focused on resolving underlying issues or gaining insight into the origins of one’s illness is unlikely to be effective in resolving eating disorder symptoms
• That behaviorally-based psychological treatments focused on symptom management and skills building can be very effective, in large part because they change the brain
• That last century’s theories about the causes of eating disorders are inaccurate

I wish that Harris and Steele, and all professionals involved researching or treating eating disorders, could grasp these points. If the general population had this basic understanding of eating disorders, then patients and their families would be viewed with compassion and understanding rather than judgment or smug clichés (e.g. “she needs to learn to love herself;” “it’s all about control”).

The past decade represents a monumental shift in the way expert clinicians view eating disorders. In fact, it will be 10 years ago this fall that I saw my very first eating disorder patient. As a bright-eyed graduate student hungry for hands-on clinical experience, I chose a training rotation at an adolescent eating disorders clinic. On my first day at the clinic, not much older or wiser than the teenagers I was about to start treating, I was introduced to “the Maudsley Approach,” a promising new treatment method from the UK. And the rest, as they say, was history.
