16.2 Evaluating Psychotherapies

Advice columnists frequently urge their troubled letter writers to get professional help: “Seek counseling” or “Ask your mate to find a therapist.”

Many Americans share this confidence in psychotherapy’s effectiveness. Before 1950, psychiatrists were the primary providers of mental health care. Today’s providers include clinical and counseling psychologists, clinical social workers, clergy, marital and school counselors, and psychiatric nurses. With such an enormous outlay of time as well as money, effort, and hope, it is important to ask: Are the millions of people worldwide justified in placing their hopes in psychotherapy?

Is Psychotherapy Effective?

16-8 Does psychotherapy work? How can we know?

The question, though simply put, is not simple to answer. Measuring therapy’s effectiveness is not like taking your body’s temperature after a fever. So how can we assess psychotherapy’s effectiveness? By how we feel about our progress? By how our therapist feels about it? By how our friends and family feel about it? By how our behavior has changed?

Clients’ Perceptions

If clients’ testimonials were the only measuring stick, we could strongly affirm psychotherapy’s effectiveness. When 2900 Consumer Reports readers (1995; Kotkin et al., 1996; Seligman, 1995) related their experiences with mental health professionals, 89 percent said they were at least “fairly well satisfied.” Among those who recalled feeling fair or very poor when beginning therapy, 9 in 10 now were feeling very good, good, or at least so-so. We have their word for it—and who should know better?

We should not dismiss these testimonials. But for several reasons, client testimonials do not persuade psychotherapy’s skeptics:

Trauma: These women were mourning the tragic loss of lives and homes in the 2010 earthquake in China. Those who suffer through such trauma may benefit from counseling, though many people recover on their own or with the help of supportive relationships with family and friends. “Life itself still remains a very effective therapist,” noted psychodynamic therapist Karen Horney (Our Inner Conflicts, 1945).

As earlier chapters document, we are prone to selective and biased recall and to making judgments that confirm our beliefs. Consider the testimonials gathered in a massive experiment with over 500 Massachusetts boys, aged 5 to 13 years, many of whom seemed bound for delinquency. By the toss of a coin, half the boys were assigned to a 5-year treatment program. The treated boys were visited by counselors twice a month. They participated in community programs, and they received academic tutoring, medical attention, and family assistance as needed. Some 30 years later, Joan McCord (1978, 1979) located 485 participants, sent them questionnaires, and checked public records from courts, mental hospitals, and other sources. Was the treatment successful?

674

Client testimonials were glowing. Some men noted that, had it not been for their counselors, “I would probably be in jail,” “My life would have gone the other way,” or “I think I would have ended up in a life of crime.” Court records offered apparent support: Even among the “difficult” boys in the treatment group, 66 percent had no official juvenile crime record.

But recall psychology’s most powerful tool for sorting reality from wishful thinking: the control group. For every boy in the treatment group, there was a similar boy in a control group, receiving no counseling. Of these untreated men, 70 percent had no juvenile record. On several other measures, such as a record of having committed a second crime, alcohol use disorder, death rate, and job satisfaction, the untreated men exhibited slightly fewer problems. The glowing testimonials of those treated had been unintentionally deceiving.

Clinicians’ Perceptions

Do clinicians’ perceptions give us any more reason to celebrate? Case studies of successful treatment abound. The problem is that clients justify entering psychotherapy by emphasizing their unhappiness and justify leaving by emphasizing their well-being. Therapists treasure compliments from clients as they say good-bye or later express their gratitude, but they hear little from clients who experience only temporary relief and seek out new therapists for their recurring problems. Thus, the same person—with the same recurring anxieties, depression, or marital difficulty—may be a “success” story in several therapists’ files.

Because people enter therapy when they are extremely unhappy, and usually leave when they are less unhappy, most therapists, like most clients, testify to therapy’s success—regardless of the treatment.

Outcome Research

How, then, can we objectively measure the effectiveness of psychotherapy? How can we determine which people and problems are helped, and by what type of psychotherapy?

In search of answers, psychologists have turned to controlled research studies. Similar research in the 1800s transformed the field of medicine. Physicians, skeptical of many of the fashionable treatments (bleeding, purging, infusions of plant and metal substances), began to realize that many patients got better on their own, without these treatments, and that others died despite them. Sorting fact from superstition required observing patients with and without a particular treatment. Typhoid fever patients, for example, often improved after being bled, convincing most physicians that the treatment worked. Not until a control group was given mere bed rest—and 70 percent were observed to improve after five weeks of fever—did physicians learn, to their shock, that the bleeding was worthless (Thomas, 1992).

In psychology, the opening challenge to the effectiveness of psychotherapy was issued by British psychologist Hans Eysenck (1952). Launching a spirited debate, he summarized studies showing that two-thirds of those receiving psychotherapy for non-psychotic disorders improved markedly. To this day, no one disputes that optimistic estimate.

meta-analysis a procedure for statistically combining the results of many different research studies.

Why, then, are we still debating psychotherapy’s effectiveness? Because Eysenck also reported similar improvement among untreated persons, such as those who were on waiting lists. With or without psychotherapy, he said, roughly two-thirds improved noticeably. Time was a great healer.

Later research revealed shortcomings in Eysenck’s analyses; his sample was small (only 24 studies of psychotherapy outcomes in 1952). Today, hundreds of studies are available. The best are randomized clinical trials, in which researchers randomly assign people on a waiting list to therapy or to no therapy, and later evaluate everyone, using tests and assessments by others who don’t know whether therapy was given. The results of many such studies are then digested by means of meta-analysis, a statistical procedure that combines the conclusions of a large number of different studies. Simply said, meta-analyses give us the bottom-line result of lots of studies.

675

Therapists welcomed the first meta-analysis of some 475 psychotherapy outcome studies (Smith et al., 1980). It showed that the average therapy client ends up better off than 80 percent of the untreated individuals on waiting lists (FIGURE 16.3). The claim is modest—by definition, about 50 percent of untreated people also are better off than the average untreated person. Nevertheless, Mary Lee Smith and her colleagues exulted that “psychotherapy benefits people of all ages as reliably as schooling educates them, medicine cures them, or business turns a profit” (p. 183).

Figure 16.3
Treatment versus no treatment These two normal distribution curves based on data from 475 studies show the improvement of untreated people and psychotherapy clients. The outcome for the average therapy client surpassed the outcome for 80 percent of the untreated people. (Data from Smith et al., 1980.)

Dozens of subsequent summaries have now examined psychotherapy’s effectiveness. Their verdict echoes the results of the earlier outcome studies: Those not undergoing therapy often improve, but those undergoing therapy are more likely to improve, and to improve more quickly and with less risk of relapse. Moreover, between treatment sessions for depression and anxiety, many people experience sudden symptom reductions. Those “sudden gains” bode well for long-term improvement (Aderka et al., 2012).

Is psychotherapy also cost-effective? Again, the answer is Yes. Studies show that when people seek psychological treatment, their search for other medical treatment drops—by 16 percent in one digest of 91 studies (Chiles et al., 1999). Given the staggering annual cost of psychological disorders and substance abuse—including crime, accidents, lost work, and treatment—psychotherapy is a good investment, much like money spent on prenatal and well-baby care. Both reduce long-term costs. Boosting employees’ psychological well-being, for example, can lower medical costs, improve work efficiency, and diminish absenteeism.

But note that the claim—that psychotherapy, on average, is somewhat effective— refers to no one therapy in particular. It is like reassuring lung-cancer patients that “on average,” medical treatment of health problems is effective. What people want to know is the effectiveness of a particular treatment for their specific problems.

RETRIEVAL PRACTICE

  • How might the placebo effect bias clients’ and clinicians’ appraisals of the effectiveness of psychotherapies?

The placebo effect is the healing power of belief in a treatment. Patients and therapists who expect a treatment to be effective may believe it was.

Which Psychotherapies Work Best?

16-9 Are some psychotherapies more effective than others for specific disorders?

So what can we tell people considering psychotherapy, and those paying for it, about which psychotherapy will be most effective for their problem? The statistical summaries and surveys fail to pinpoint any one type of therapy as generally superior (Smith et al., 1977, 1980). Clients seemed equally satisfied, Consumer Reports concluded, whether treated by a psychiatrist, psychologist, or social worker; whether seen in a group or individual context; whether the therapist had extensive or relatively limited training and experience (Seligman, 1995). Other studies concur (Barth et al., 2013). There is little if any connection between clinicians’ experience, training, supervision, and licensing and their clients’ outcomes (Luborsky et al., 2002; Wampold, 2007).

“Whatever differences in treatment efficacy exist, they appear to be extremely small, at best.”

Bruce Wampold et al. (1997)

676

So, was the dodo bird in Alice in Wonderland right: “Everyone has won and all must have prizes”? Not quite. Some forms of therapy get prizes for particular problems, though there is often an overlapping—or comorbidity—of disorders. Behavioral conditioning therapies, for example, have achieved especially favorable results with specific behavior problems, such as bed-wetting, phobias, compulsions, marital problems, and sexual dysfunctions (Baker et al., 2008; Hunsley & DiGiulio, 2002; Shadish & Baldwin, 2005). Psychodynamic therapy has helped treat depression and anxiety (Driessen et al., 2010; Leichsenring & Rabung, 2008; Shedler, 2010b). With mild to moderate depression, nondirective (client-centered) counseling often helps (Cuijpers et al., 2013). And new studies confirm cognitive and cognitive-behavioral therapy’s effectiveness (some say superiority) in coping with anxiety, posttraumatic stress disorder, and depression (Baker et al., 2008; De Los Reyes & Kazdin, 2009; Stewart & Chambless, 2009; Tolin, 2010).

Moreover, we can say that therapy is most effective when the problem is clear-cut (Singer, 1981; Westen & Morrison, 2001). Those who experience phobias or panic, who are unassertive, or who are frustrated by sexual performance problems can hope for improvement. Those with less-focused problems, such as depression and anxiety, usually benefit in the short term but often relapse later. The more specific the problem, the greater the hope.

“Different sores have different salves.”

English proverb

But no prizes—and little or no scientific support—go to certain other therapies (Arkowitz & Lilienfeld, 2006). We would all therefore be wise to avoid energy therapies that propose to manipulate people’s invisible energy fields, recovered-memory therapies that aim to unearth “repressed memories” of early child abuse (Chapter 8), and rebirthing therapies that engage people in reenacting the supposed trauma of their birth.

As with some medical treatments, it’s possible for psychological treatments to be not only ineffective but also harmful—by making people worse or preventing their getting better (Barlow, 2010; Castonguay et al., 2010; Dimidjian & Hollon, 2010). The National Science and Technology Council cites the Scared Straight program (seeking to deter children and youth from crime) as an example of well-intentioned programs that have proved ineffective or even harmful.

The evaluation question—which therapies get prizes and which do not?—lies at the heart of what some call psychology’s civil war. To what extent should science guide both clinical practice and the willingness of health care providers and insurers to pay for psychotherapy?

evidence-based practice clinical decision making that integrates the best available research with clinical expertise and patient characteristics and preferences.

On the one side are research psychologists using scientific methods to extend the list of well-defined and validated therapies for various disorders. They decry clinicians who “give more weight to their personal experiences” (Baker et al., 2008). On the other side are non-scientist therapists who view their practice as more art than science, saying that people are too complex and therapy too intuitive to describe in a manual or test in an experiment. Between these two factions stand the science-oriented clinicians, who aim to base practice on evidence and make mental health professionals accountable for effectiveness.

To encourage evidence-based practice in psychology, the American Psychological Association and others (2006; Lilienfeld et al., 2013) urge clinicians to integrate the best available research with clinical expertise and with patient preferences and characteristics. Available therapies “should be rigorously evaluated” and then applied by clinicians who are mindful of their skills and of each patient’s unique situation (FIGURE 16.4). Increasingly, insurer and government support for mental health services requires evidence-based practice.

Evaluating Alternative Therapies

16-10 How do alternative therapies fare under scientific scrutiny?

The tendency of many abnormal states of mind to return to normal, combined with the placebo effect (the healing power of mere belief in a treatment), creates fertile soil for pseudotherapies. Bolstered by anecdotes, heralded by the media, and broadcast on the Internet, alternative therapies can spread like wildfire. In one national survey, 57 percent of those with a history of anxiety attacks and 54 percent of those with a history of depression had used alternative treatments, such as herbal medicine, massage, and spiritual healing (Kessler et al., 2001).

Testimonials aside, what does the evidence say? This is a tough question, because there is no evidence for or against most of them, though their proponents often feel personal experience is evidence enough. Some, however, have been the subject of controlled research. Let’s consider two of these. As we do, remember that sifting sense from nonsense requires the scientific attitude: being skeptical but not cynical, open to surprises but not gullible.

Eye Movement Desensitization and Reprocessing (EMDR)

EMDR (eye movement desensitization and reprocessing) is a therapy adored by thousands and dismissed by thousands more as a sham—“an excellent vehicle for illustrating the differences between scientific and pseudoscientific therapy techniques,” suggested James Herbert and seven others (2000). Francine Shapiro (1989, 2007, 2012) developed EMDR while walking in a park and observing that anxious thoughts vanished as her eyes spontaneously darted about. Back in the clinic, she had people imagine traumatic scenes while she triggered eye movements by waving her finger in front of their eyes, supposedly enabling them to unlock and reprocess previously frozen memories. Tens of thousands of mental health professionals from more than 75 countries have since undergone training (EMDR, 2011). Not since the similarly charismatic Franz Anton Mesmer introduced animal magnetism (hypnosis) more than two centuries ago (also after feeling inspired by an outdoor experience) has a new therapy attracted so many devotees so quickly.

Does it work? For 84 to 100 percent of single-trauma victims participating in four studies, the answer is Yes, reports Shapiro (1999, 2002). Moreover, the treatment need take no more than three 90-minute sessions. The Society of Clinical Psychology task force on empirically validated treatments acknowledges that EMDR is “probably efficacious” for the treatment of nonmilitary posttraumatic stress disorder (Chambless et al., 1997; see also Bisson & Andrew, 2007; Rodenburg et al., 2009; Seidler & Wagner, 2006).

“Studies indicate that EMDR is just as effective with fixed eyes. If that conclusion is right, what’s useful in the therapy (chiefly behavioral desensitization) is not new, and what’s new is superfluous.”

Harvard Mental Health Letter, 2002

Why, wonder the skeptics, would rapidly moving one’s eyes while recalling traumas be therapeutic? Some argue that eye movements serve to relax or distract patients, thus allowing the memory-associated emotions to extinguish (Gunter & Bodner, 2008). Others believe that eye movements in themselves are not the therapeutic ingredient (nor is watching high-speed Ping-Pong therapeutic). Trials in which people imagined traumatic scenes and tapped a finger, or just stared straight ahead while the therapist’s finger wagged, have also produced therapeutic results (Devilly, 2003). EMDR does work better than doing nothing, acknowledge the skeptics (Lilienfeld & Arkowitz, 2007). But skeptics suspect that what is therapeutic is the combination of exposure therapy—repeatedly calling up traumatic memories and reconsolidating them in a safe and reassuring context—and perhaps some placebo effect. Had Mesmer’s pseudotherapy been compared with no treatment at all, it, too (thanks to the healing power of positive belief), might have been found “probably efficacious,” observed Richard McNally (1999).

678

Light Exposure Therapy

Light therapy To counteract winter depression, some people spend time each morning exposed to intense light that mimics natural outdoor light. Light boxes are available from health supply and lighting stores.

Have you ever found yourself oversleeping, gaining weight, and feeling lethargic during the dark mornings and overcast days of winter? There likely was a survival advantage to your distant ancestors’ slowing down and conserving energy during the dark days of winter. For some people, however, especially women and those living far from the equator, the wintertime blahs constitute a seasonal pattern for major depressive disorder. To counteract these dark spirits, National Institute of Mental Health researchers in the early 1980s had an idea: Give people a timed daily dose of intense light. Sure enough, people reported they felt better.

Was light exposure a bright idea, or another dim-witted example of the placebo effect? Research sheds some light. One study exposed some people with a seasonal pattern in their depression symptoms to 90 minutes of bright light and others to a sham placebo treatment—a hissing “negative ion generator” about which the staff expressed similar enthusiasm (but which was not even turned on). After four weeks, 61 percent of those exposed to morning light had greatly improved, as had 50 percent of those exposed to evening light and 32 percent of those exposed to the placebo (Eastman et al., 1998). Other studies have found that 30 minutes of exposure to 10,000-lux white fluorescent light produced relief for more than half the people receiving morning light therapy (Flory et al., 2010; Terman et al., 1998, 2001). From 20 carefully controlled trials we have a verdict (Golden et al., 2005; Wirz-Justice, 2009): Morning bright light does indeed dim depression symptoms for many of those suffering in a seasonal pattern. Moreover, it does so as effectively as taking antidepressant drugs or undergoing cognitive-behavioral therapy (Lam et al., 2006; Rohan et al., 2007). The effects are clear in brain scans; light therapy sparks activity in a brain region that influences the body’s arousal and hormones (Ishida et al., 2005).

How Do Psychotherapies Help People?

16-11 What three elements are shared by all forms of psychotherapy?

Why have studies found little correlation between therapists’ training and experience and clients’ outcomes? In search of some answers, clinical researchers have studied the common ingredients of various therapies (Frank, 1982; Goldfried & Padawer, 1982; Strupp, 1986; Wampold, 2001, 2007). Their conclusion: They all offer at least three benefits:

679

therapeutic alliance a bond of trust and mutual understanding between a therapist and client, who work together constructively to overcome the client’s problem.

The emotional bond between therapist and client—the therapeutic alliance— helps explain why some therapists are more effective than others (Klein et al., 2003; Wampold, 2001). One U.S. National Institute of Mental Health depression-treatment study confirmed that the most effective therapists were those who were perceived as most empathic and caring and who established the closest therapeutic bonds with their clients (Blatt et al., 1996). That all therapies offer hope through a fresh perspective offered by a caring person is what also enables paraprofessionals (briefly trained caregivers) to assist so many troubled people so effectively (Christensen & Jacobson, 1994).

These three common elements are also part of what the growing numbers of self-help and support groups offer their members. And they are part of what traditional healers have offered (Jackson, 1992). Healers everywhere—special people to whom others disclose their suffering, whether psychiatrists, witch doctors, or shamans—have listened in order to understand and to empathize, reassure, advise, console, interpret, or explain (Torrey, 1986). Such qualities may explain why people who feel supported by close relationships—who enjoy the fellowship and friendship of caring people—are less likely to need or seek therapy (Frank, 1982; O’Connor & Brown, 1984).

***

To recap, people who seek help usually improve. So do many of those who do not undergo psychotherapy, and that is a tribute to our human resourcefulness and our capacity to care for one another. Nevertheless, though the therapist’s orientation and experience appear not to matter much, people who receive some psychotherapy usually improve more than those who do not. People with clear-cut, specific problems tend to improve the most.

Culture and Values in Psychotherapy

16-12 How do culture and values influence the therapist-client relationship?

All therapies offer hope, and nearly all therapists attempt to enhance their clients’ sensitivity, openness, personal responsibility, and sense of purpose (Jensen & Bergin, 1988). But therapists also differ from one another and may differ from their clients (Delaney et al., 2007; Kelly, 1990).

These differences can become significant when a therapist from one culture meets a client from another. In North America, Europe, and Australia, for example, most therapists reflect their culture’s individualism, which often gives priority to personal desires and identity, particularly for men. Clients who are immigrants from Asian countries, where people are mindful of others’ expectations, may have trouble relating to therapies that require them to think only of their own well-being. Such differences help explain minority populations’ reluctance to use mental health services, and their tendency to prematurely terminate therapy (Chen et al., 2009; Sue, 2006). In one experiment, Asian-American clients matched with counselors who shared their cultural values (rather than mismatched with those who did not) perceived more counselor empathy and felt a stronger alliance with the counselor (Kim et al., 2005). Recognizing that therapists and clients may differ in their values, communication styles, and language, all American Psychological Association–accredited therapy training programs now provide training in cultural sensitivity and welcome members of underrepresented cultural groups.

Another area of potential values-related conflict is religion. Highly religious people may prefer and benefit from religiously similar therapists (Masters, 2010; Smith et al., 2007; Wade et al., 2006). They may have trouble establishing an emotional bond with a therapist who does not share their values. Because clients tend to adopt their therapists’ values (Worthington et al., 1996), some psychologists believe therapists should divulge their values. Today’s professional training programs also seek to train therapists from diverse backgrounds who can relate, with sensitivity, to diverse clients.

Finding a Mental Health Professional

16-13 What should a person look for when selecting a therapist?

Life for everyone is marked by a mix of serenity and stress, blessing and bereavement, good moods and bad. So, when should we seek a mental health professional’s help? The American Psychological Association offers these common trouble signals:

In looking for a therapist, you may want to have a preliminary consultation with two or three. College health centers are generally good starting points, and may offer some free services. You can describe your problem and learn each therapist’s treatment approach. You can ask questions about the therapist’s values, credentials (TABLE 16.3), and fees. And you can assess your own feelings about each of them. The emotional bond between therapist and client is perhaps the most important factor in effective therapy.

Research suggests that trying to answer these questions on your own will improve your long-term retention (McDaniel et al., 2009).

16-8 Does psychotherapy work? How can we know?

Clients’ and therapists’ positive testimonials cannot prove that psychotherapy is actually effective, and the placebo effect makes it difficult to judge whether improvement occurred because of the treatment.
     Using meta-analyses to statistically combine the results of hundreds of randomized psychotherapy outcome studies, researchers have found that those not undergoing treatment often improve, but those undergoing psychotherapy are more likely to improve more quickly, and with less chance of relapse.

16-9 Are some psychotherapies more effective than others for specific disorders?

No one type of psychotherapy is generally superior to all others. Therapy is most effective for those with clear-cut, specific problems. Some therapies—such as behavior conditioning for treating phobias and compulsions—are more effective for specific disorders. Psychodynamic therapy has been effective for depression and anxiety, and cognitive and cognitive-behavioral therapies have been effective in coping with anxiety, posttraumatic stress disorder, and depression. Evidence-based practice integrates the best available research with clinicians’ expertise and patients’ characteristics, preferences, and circumstances.

16-10 How do alternative therapies fare under scientific scrutiny?

Abnormal states tend to return to normal on their own, and the placebo effect can create the impression that a treatment has been effective. These two tendencies complicate assessments of alternative therapies (nontraditional therapies that claim to cure certain ailments). Eye movement desensitization and reprocessing (EMDR) has shown some effectiveness—not from the eye movement but rather from the exposure therapy nature of the treatments. Light exposure therapy does seem to relieve depression symptoms for those with a seasonal pattern of major depressive disorder by activating a brain region that influences arousal and hormones.

16-11 What three elements are shared by all forms of psychotherapy?

All psychotherapies offer new hope for demoralized people; a fresh perspective; and (if the therapist is effective) an empathic, trusting, and caring relationship. The emotional bond of trust and understanding between therapist and client—the therapeutic alliance—is an important element in effective therapy.

16-12 How do culture and values influence the therapist-client relationship?

Therapists differ in the values that influence their goals in therapy and their views of progress. These differences may create problems if therapists and clients differ in their cultural or religious perspectives.

16-13 What should a person look for when selecting a therapist?

A person seeking therapy may want to ask about the therapist’s treatment approach, values, credentials, and fees. An important consideration is whether the therapy seeker feels comfortable and able to establish a bond with the therapist.
