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, and 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.

What’s That About?

“It’s about control.”

This statement has been applied to everything from OCD to eating disorders to self-injury to domestic violence. But, really, what does this statement mean?

When I hear that X is about Y, I generally interpret this statement in one of two ways: 1.) Y is a theme of X or 2.) Y is the most salient feature of X. For example, if someone says that Romeo and Juliet is about undying love, my interpretation is that undying love is a primary theme of Romeo and Juliet. Or if someone says: “My birthday is about me,” I interpret that as “I am the most important person on my birthday” in terms of attention, presents, and deciding how to celebrate.

In regards to the cliché that a certain psychological problem is about control, both of these interpretations make sense to a certain extent. Control is both a theme and a salient feature of OCD insofar as sufferers are overly preoccupied with controlling their external environment, as well as their thoughts and actions related to their particular obsession. For example, a person with OCD may spend hours scrubbing her body and cleaning her home in order to control the spread of germs and prevent herself or others from becoming ill.

Control is both a theme and a salient feature of eating disorders insofar as sufferers become preoccupied with controlling their dietary intake, exercise, and weight. Individuals with anorexia tend to be “over-controlled,” rigid, and perfectionistic not only with food but in other areas of their lives, while individuals with bulimia experience periods of “dyscontrol” of their emotions and food intake, resulting in binge /purge episodes.

Control is both a theme and a salient feature in the lives of individuals who engage in self-injurious behaviors such as cutting. Many, though not all, individuals who cut have experienced physical or sexual abuse, which results in feeling a lack of personal control over one’s life and one’s body. People who cut usually experience overwhelming emotions that they are unable to control. Some people use self-injury as an interpersonal message with an intent to control or manipulate others.

Control is both a theme and a salient feature in cycles of domestic violence. Through subtle and overt messages, abusers control and manipulate their victims. It is easy for abusers to control their victims because the victims are usually smaller and physically weaker than they are. In most cases, abusers have financial and / or emotional control over their victims. And, sadly, victims feel a devastating loss of personal control over their own lives.

I am concerned, however, that people who claim that a mental illness or psychological phenomenon is about control have an entirely different interpretation of this phrase. For most people, I think “It’s about control” translates to “it is caused by a lack of control or a need for control.” This interpretation has no empirical backing and, when espoused by treatment professionals, leads to ineffective treatment.

For instance, many therapists believe that eating disorders are “about control,” meaning that they believe that the etiology of eating disorders is rooted in a subconscious need for control. As a result of this theory, their treatment entails helping the patient gain a sense of personal control in other areas of her life, and advising her parents to “back off” of the power struggle around meals, with the assumption that eventually the patient will no longer feel the need to control her food intake.

There is no scientific basis for this theory or this treatment approach, and I have never met a person who has recovered this way. I’m sure such people exist, I’ve just never seen them. I would presume that these individuals went through years of treatment, suffered numerous medical and psychological problems, and spent many thousands of dollars before finally recovering. Recent scientific evidence suggests that eating disorders are biologically-based, genetically transmitted brain diseases that are triggered by an energy imbalance and perpetuated by malnutrition. There’s no room for “control” in this etiology.

While I’m on the subject of about, there’s another use of the word about that perplexes and frustrates me. Case in point: a very well-regarded eating disorder recovery website has the following mission statement on its homepage:

“We are dedicated to raising awareness about eating disorders… emphasizing always that eating disorders are NOT about food and weight.”

What does this mean? Surely, it cannot mean that food and weight are not themes in eating disorders. Nor can it mean that disturbances in food and weight are not a salient feature of eating disorders. By definition, individuals with eating disorders manifest disturbances in eating behavior, weight loss, or excessive preoccupation with weight. I can only assume, then, that this statement means that eating disorders are not caused by food and weight (or disturbances thereof). If this is the meaning of the mission statement, then the statement is undeniably false.

The latest scientific research tells us that eating disorders are, in fact, set into motion by disturbances in eating and weight. A person with a biological predisposition to anorexia nervosa or bulimia nervosa will not develop the illness unless he or she experiences a disturbance in eating and/or weight. Anorexia nervosa and bulimia nervosa are triggered by under-nutrition, which may initially be intentional (e.g., the decision to diet, “eat healthy,” or exercise more) or unintentional (e.g., the result of an illness, surgery, injury, medication, or another mental illness such as depression). The cycle of starvation in anorexia nervosa is maintained by malnutrition, and the illness is most severe and most deadly when the patient is underweight. The restrict/binge/purge cycle in bulimia nervosa is also self-perpetuating and is triggered or exacerbated by disturbances in eating behavior and preoccupation with weight. Full nutrition, weight restoration, cessation of restricting, bingeing, and purging behaviors, and decrease in preoccupation with weight are essential for full recovery. In conclusion, eating disorders are absolutely about food and weight. To neglect this perfectly obvious fact is to sabotage treatment.

Scientist-practitioner ranting notwithstanding, I think I do understand what that mission statement is intending to communicate. I think it is trying to convey that eating disorders are not just about food and weight; they also entail tremendous psychological suffering. I think the statement is trying to emphasize that correction of disturbances in eating and weight is not sufficient for full recovery, as psychological issues must be addressed as well. Finally, I think the statement hopes to convey that eating disorders are serious mental illnesses that bear little resemblance to typical dieting and body image woes.

While I applaud the website’s attempt to convey the aforementioned messages, I think the way the statement is worded has the potential to create a misunderstanding (or, at the very least, it doesn’t bring people closer to an accurate understanding). I’m guessing that eating disorder sufferers and their families, as well as the general public, will misinterpret the message, most likely in the manner I described. The consequences of such misinterpretation can be tragic.

We have a responsibility to people with eating disorders to provide them, and their families, with accurate information. Further, we have a responsibility to educate the public about eating disorders in order to reduce stigma, garner support, facilitate early detection, and lobby for more effective treatment. To start, let’s make sure the messages about eating disorders that we send, whether in person, in print, or on the internet, are accurate, understandable, easy to interpret, and scientifically-sound.

Isn’t it about time?

Biologically-Based Mental Illnesses

As a result of the Mental Health Parity Act, many health insurance companies are now providing the same coverage for biologically-based mental illnesses as they provide for other medical illnesses. A biologically-based conceptualization of mental illness allows advocates to frame parity legislation as antidiscrimination legislation. Using PET scans and MRI’s, researchers have testified before Congress and state legislatures that mental illness is directly linked to brain dysfunction. In light of such evidence, policy makers have been persuaded to admit that certain mental illnesses are brain disorders (Peck & Scheffler, 2002). I see this as a double-edged sword.

On the positive side, it is wonderful that individuals with certain mental illnesses are now getting the insurance coverage they so desperately need. I am a huge proponent of equitable services for all people with mental illnesses. Additionally, I am pleased to see that the tide is beginning to turn in regards to society’s attitudes about psychiatric problems. This is undoubtedly a good start. But it is only a start.

There are a number of problems with the concept of biologically-based mental illnesses as defined by insurance companies:

1.) They are creating a false dichotomy by differentiating between biologically-based and non-biologically based mental illnesses. Empirical evidence challenges the discriminant validity of the “biologically based mental illness” construct. Psychotherapy and medication yield similar changes in brain function when effective. Drug and brain imaging studies show that psychological and biochemical phenomena can be manipulated reciprocally (Seidel, 2005). The truth is, ALL mental illnesses are biologically-based because all mental functioning is biologically-based. Western society clings to the 17th century notion of Cartesian dualism; that is, the idea that mind and body are separate. But let’s take a closer look. The word “mind,” as used today, refers to intellect and consciousness, manifested as combinations of thought, perception, memory, emotion, will, and imagination, including all of the brain’s conscious and unconscious cognitive processes. And where do these cognitive processes originate? In the brain, which is part of our biology! Every thought and feeling we have, every perception and wish and behavior, has a corresponding neurobiological substrate.

2.) The insurance company’s decisions about which mental illnesses to classify as biologically-based seem rather arbitrary. Some insurance companies only classify schizophrenia, bipolar disorder, and OCD as biologically-based, while other insurance companies cover other disorders as well. For example, one major health insurance company defines biologically-based mental illness as “a mental or nervous condition that is caused by a biological disorder of the brain and results in a clinically significant psychological syndrome or pattern that substantially limits the functioning of the person with the illness.” This insurance company classifies the following as biologically-based mental illnesses: Schizophrenia, Schizo-affective Disorder, Major Depressive Disorder, Bipolar Disorder, Paranoia and other Psychotic Disorders, OCD, Panic Disorder, Pervasive Developmental Disorder, Autism, and Alcohol Abuse Disorders. This same insurance company defines non-biologically-based mental illness as conditions that “display symptoms that are primarily mental or nervous in nature. The primary treatment is psychotherapy or psychotropic medication.” I don’t understand this distinction at all. All of the biologically-based mental illnesses they listed are “mental or nervous in nature” and treatment for all of them includes behavior therapy, psychotherapy and / or psychotropic medication. Further, why is alcoholism considered biologically based, whereas are addictions to substances other than alcohol considered “non-biologically based?” And why is anorexia nervosa, which has numerous biological features and complications, a heritability estimate as high as that of schizophrenia and bipolar disorder, and the highest mortality rate of any psychiatric illness, considered a non-biologically based mental illness?

3.) The erroneous classification of certain mental illnesses as non-biologically based serves to increase stigma and discrimination against individuals with these illnesses. There is a subtle implication that so-called non-biologically based mental illnesses are not as serious, not as legitimate, or not as real as so-called biologically-based mental illnesses. Further, there is an even subtler implication that non-biologically-based mental illnesses are somehow the patient’s fault or the patient’s choice. It is as if they are saying: “It’s all in your head.” Well, yes, but so are Alzheimer’s Disease and brain cancer!

4.) I’m not sure why illnesses of the brain, whether they are classified as “biologically-based” or not, should be considered any different from illnesses of the heart, lungs, liver, or kidneys. Is it because environment and lifestyle, rather than biology, are presumed to be the cause? The development of heart disease, Type II diabetes, skin cancer, and AIDS are all heavily influenced by environment and lifestyle choices, and no one would argue that these diseases are not biologically-based. People with these diseases are not discriminated against in insurance coverage.
