Cognitive therapy helps people change the way they think, act
By Benedict Carey
And because it's not a prescription drug, there are no side effects.
As health officials around the world debate the risks of antidepressant drugs such as Prozac and Paxil, doctors are re-evaluating standard treatments for conditions from depression to obsessive compulsive disorder to panic attacks. Some say antidepressants have been oversold; most say that they're being needlessly vilified.
Largely ignored amid the controversy is one alternative that has proven itself as versatile and effective against mental illness as any antidepressant.
Cognitive behavior therapy, a short-term talking cure, helps people make small, seemingly mundane changes in the way they think (the cognitive) and act (the behavioral) that can produce profound and lasting recovery.
Although it came of age in the 1980s as a treatment for depression, the therapy has proved itself effective in recent years against more than a dozen illnesses in which mental distress plays some part.
The treatment would be much more widely known and used, experts say, if not for a shortage of trained specialists, spotty insurance coverage and patients' preference for the ease and convenience of pills. The popularity of TV's Dr. Phil notwithstanding, they say, the idea of private psychotherapy still carries a whiff of indulgence, mental fragility and neurotic self-absorption.
"We really have become a Prozac nation, in the sense that drug prescribing is going up, and the use of talk therapy is declining," said Mark Reinecke, chief of the psychology division at Northwestern University Medical School in Chicago. "The fact is that most people don't realize how effective this therapy can be and still associate it with traditional psychoanalysis."
Tools to break habits
As first formulated in the 1960s by Dr. Aaron Beck, a psychiatrist, and psychologist Albert Ellis, cognitive therapy was an open rejection of psychoanalysis. Whereas Sigmund Freud probed the depths of the unconscious to explain behavior and mental illness, Beck and Ellis stayed in the shallows.
The two argued that depression was not the result of cryptic, unconscious forces but rather of conscious, seemingly trivial negative assumptions and thinking. Maybe, they reasoned, these patterns of self-critical, pessimistic thinking are the disease, not merely symptoms.
Cognitive techniques are meant to help people recognize those habits and provide tools to break them.
First, people learn to identify thought patterns, dark assumptions that often become self-fulfilling ("I'm a terrible parent"; "I don't do well on tests"; "I'm unlucky in love.") They then begin disputing these assumptions, using logic and evidence, engaging in a sort of internal debate with themselves. (For example: "Hold on, I've had several long-term, loving relationships.")
Ideally, this Socratic dialogue helps people develop alternate explanations for future difficulties. ("I'm not a bad parent, I'm merely impatient when I'm trying to work.")
They're also taught ways to distract themselves from brooding over loss, betrayal, humiliation or other disquieting memories the kind of rumination that can be paralyzing in everyday life.
Activity by itself can be distracting. A walk to the post office can lift one's spirit. So can having lunch with a friend or going for a jog.
As most people know through experience (but often forget), the simple act of starting work on a challenging project can quickly ease the dread of failure, said Kenneth Reinhard, director of the anxiety disorders clinic at the Hudson Valley Veterans Administration medical center in Montrose, N.Y.
By engaging in various activities with the purpose of interrupting harmful rumination or inertia, people can learn in therapy to complement their thought management with behavior, their thinking with action, Reinhard said.
The unexamined beliefs that drag people into chronic depression often are rooted in childhood, and therapists have to explore early memories, as in more traditional analysis.
Any effective therapy can stir sensations or emotions that are initially upsetting or disruptive. Arguments at home and strained relationships are actual side effects of talk therapy, psychiatrists said.
Depending on the condition being treated, anywhere from 30 percent to more than half of patients find cognitive therapy too disruptive, demanding or ineffectual to benefit from it.
But for many people with stubborn mental problems, recent research suggests that it's worth a try:
In a study of 187 hypochondriacs, Harvard researchers found that six weekly sessions of cognitive behavior therapy significantly eased patients' anxieties over daily aches and pains and allowed them to live more normal lives, relatively free of the dread that, say, a bad headache was because of a brain tumor.
Hypochondriacs often suffer under mistaken assumptions like "I have to be 100 percent certain that I am not ill," or "A bodily symptom is always a sign of serious disease." The men and women still had psychosomatic symptoms after undergoing the therapy, but they were less likely than before to call the doctor or to panic, the researchers reported.
Dutch researchers reported that patients suffering from chronic fatigue syndrome were about three times more likely to improve using cognitive behavior counseling than with standard group-therapy sessions. After eight months of weekly cognitive sessions, about a third of patients reported more energy and lower medical costs.
In a study among 131 cancer patients, researchers at the University of North Carolina tested a five-session cognitive-behavior program tailored to address pain and individuals' psychological needs. All the patients were taking prescription painkillers. Compared with standard care, which included some counseling, the individualized therapy reduced pain intensity over the first month and allowed people to walk, socialize and sleep more comfortably, the doctors said.
It takes time and effort
Although research has shown how antidepressants affect the brain drugs like Prozac act on a chemical messenger called serotonin, which affects mood it's still unclear what, if any, lasting neurological changes result from cognitive therapy.
Using brain-imaging techniques, neuroscientists have shown that cognitive talk therapy produces changes in the areas of the brain that are also affected by drug therapies. Conscious mental effort, in short, induces a distinct biological effect on the brain that's visible on brain scans.
Given its track record against depression in particular and its minimal side effects compared with drugs, cognitive behavior therapy should be more widely used as a first-line treatment, many psychologists and psychiatrists believe.
Yet such therapy typically costs $50 to more than $100 a session. And a full course of the therapy may require 12 hourlong sessions, including at-home assignments, such as keeping a diary of daily difficulties and the thoughts they prompt. By contrast, a daily dose of generic Prozac can cost less than $50 a month, there's no homework and the therapy is often fully covered by health insurance.
"The cognitive therapy takes time and effort, and for many people the time costs are high. They'd rather have medicine," said Dr. Ken Wells, a research psychiatrist at the University of California, Los Angeles, and Rand Corp., which studies trends in psychiatric care.
But not everyone wants a prescription. This spring Wells and colleagues from Rand and UCLA reported findings from a five-year study of almost 1,000 men and women with depression who tried different forms of treatment.
Some groups of depressed patients black and Hispanic populations, in particular prefer talk therapy to antidepressants, the doctors found. When given the choice of enrolling in a cognitive-behavior course and provided with financial incentives, such as low insurance co-payments, these patients were significantly more likely to shake their chronic low moods than they would have been in standard care.
And when patients show lasting benefits from short-term talk therapy, the economics begin to change. In one 1997 analysis, doctors at a Veterans Administration hospital in Reno, Nev., calculated that the cost of Prozac prescriptions and visits to a doctor outpaced the fees for a typical course of cognitive behavior therapy by 33 percent over a two-year period. (To be sure, the VA analysis was done before the expiration of Prozac's patent, a change that significantly reduced the drug's cost.)
"It's really a matter of people being informed about the therapy," said Judith Beck, director of the Beck Institute, a nonprofit cognitive-treatment clinic near Philadelphia. "When people are informed, they're usually interested, whether they've tried drugs, or want to avoid them."
One of Beck's recent patients, a 42-year-old mother of two, quit her job after suffering a sudden episode of depression. Believing that her family faced imminent financial disaster, the woman became paralyzed by her depression, barely able to get out of bed, care for her children or maintain her household, Beck said.
Beck had the mother try a few simple experiments. She asked her husband about the family finances. They were stretched but in no danger of losing the house. On one day, she called a friend to meet for lunch. On another, she went for a walk. As a matter of routine again, an experiment she started doing the breakfast dishes, instead of fretting about not having done them.
"It took 20 minutes, that's it, but it kept her from going right to bed," Beck said. "Small things; you're breaking the day down into small parts and handling them one at a time."
By small steps, the woman made her way back to work. She has not needed medication.
