Better Than Waiting? The Long Argument Over Whether Psychotherapy Works

Introduction

At the counseling center where I work as a case aide, I help clients complete intake forms and schedule appointments. Last month, the brother of a young woman starting therapy for depression told me that talking about problems never fixed anything and that she would get better on her own. I did not know how to answer. This paper examines the research history behind that question: whether psychotherapy works, how researchers came to know it and what makes it effective.

Eysenck's Challenge

Eysenck (1952) reviewed reports on the outcomes of patients with neurotic disorders, such as anxiety and depression, treated with psychoanalysis or with other forms of psychotherapy, and compared them with estimates of improvement among patients who received only custodial care or treatment from general practitioners. He concluded that about two thirds of neurotic patients improved within about two years whether or not they received psychotherapy, and that the improvement rates for treated patients were no better, and for psychoanalysis worse. He argued that the evidence failed to show that psychotherapy helped recovery. His review was criticized for comparing groups that differed in many ways and for using inconsistent definitions of improvement, but it forced the field to test its claims.

The First Meta-Analysis

Smith and Glass (1977) answered Eysenck with a new method. Rather than counting studies as successes or failures, they collected 375 controlled studies of psychotherapy and calculated an effect size for each outcome, expressing the difference between treated and untreated groups in standard deviation units. Averaging across studies, they found an effect of about two thirds of a standard deviation: the typical treated client was better off than about 75 percent of untreated controls. Differences among types of therapy, such as behavioral and psychodynamic approaches, were small once the studies were compared on similar terms. Their work introduced meta-analysis to psychology and shifted the debate from whether therapy works to how and for whom.

Common Factors

If different therapies produce similar results, what do they share? Wampold (2015) reviewed evidence for common factors, elements present in all legitimate therapies. He described a contextual model in which therapy works through three pathways: a real relationship between client and therapist, the creation of expectations through a believable explanation of the problem and a treatment plan and the client's engagement in healthy actions that the treatment promotes. He summarized meta-analyses showing that the working alliance, empathy, positive expectations, cultural adaptation of treatment and differences between individual therapists are all associated with outcomes, often more strongly than the specific techniques of a given therapy.

Research Methods in Psychotherapy

These studies illustrate the methods the course asks students to understand. Randomized controlled trials compare treated clients with waiting-list or alternative treatment groups. Meta-analysis combines many trials to estimate an average effect and test whether it varies by treatment, client or setting. Process research examines what happens in sessions, such as the strength of the alliance, and links it to outcome. No single method settles everything; combined, they reveal that therapy helps and point to the reasons.

Specific Versus Common Factors

Wampold's emphasis on common factors is debated. Researchers who favor specific treatments point out that for some conditions, such as exposure therapy for phobias and obsessive-compulsive disorder, particular techniques produce clearly better results than general support. Most clinicians now see both as important: a strong relationship and a credible, specific treatment matched to the problem.

What I Can Tell a Skeptic

The research suggests that the client's brother was partly right: many people do improve over time without treatment. But the evidence since Smith and Glass shows that people in therapy improve more than similar people who wait, and that the relationship with a skilled therapist is a large part of why. I now explain to families that therapy is not just talking; it is a structured relationship aimed at specific changes, tested in hundreds of studies.

What It Means for Our Center

Our center tracks each client's symptoms at every session with a brief questionnaire. Wampold's findings suggest that also asking clients how well they feel understood and how much they agree with the therapy's goals could help therapists notice when the alliance is weak and adjust before the client drops out.

Who Does Not Improve

Averages hide variation. Even in successful trials, a meaningful share of clients do not improve, and a small share get worse. Research on deterioration suggests that therapists often fail to notice when a client is getting worse, which is one reason routine outcome monitoring, asking clients to rate their symptoms each session, has spread. When therapists receive feedback that a client is off track, outcomes for those clients tend to improve.

Therapist Differences

Wampold also points to differences between therapists: some consistently achieve better outcomes than others, even when using the same treatment. These differences appear to relate to interpersonal skill, such as expressing empathy and repairing ruptures in the relationship, more than to years of experience or theoretical orientation. For a center, this suggests that supervision focused on relationship skills may matter as much as training in new techniques.

Limits

Eysenck's data came from very different groups. A meta-analysis is only as sound as its ingredient studies, and missing unpublished null results can inflate its estimates. Common factors research is largely correlational.

Conclusion

Eysenck challenged the field to prove that psychotherapy helps, Smith and Glass showed through meta-analysis that treated clients do better than most untreated people and Wampold argued that the alliance, empathy and expectations shared by all good therapies account for much of that benefit. The answer to a skeptical family member is that therapy works, on average, and that a trusting, purposeful relationship is a large part of how.
