Desensitization in the Treatment of Anxiety Disorders

Staying current with research literature and evidence-based practices in the treatment of anxiety disorders can be a challenge—even for experienced clinicians. At times, the language of older therapeutic models can quietly persist in our work, even when it no longer aligns with what we know to be effective. A recent case consultation reminded me just how easy it is for outdated concepts to re-enter the room under the guise of familiarity or tradition.

One therapist I supervise attended a local workshop where the presenter emphasized desensitization as a central treatment for anxiety. While once a foundational concept in behavior therapy, “desensitization” is now largely considered outdated and even counterproductive if misunderstood. It can mislead clinicians—and clients—into believing that the goal of treatment is to eliminate anxiety rather than to build tolerance for it.

Why Desensitization Is No Longer the Goal

In the early days of my practice, I, too, saw desensitization as the endpoint. I remember a young man with agoraphobia who had avoided getting a haircut for years. He feared the vulnerability of sitting in a barber’s chair. We focused eight full weeks of therapy on exposure to the haircut itself—sitting in the chair, walking past the shop, watching haircut videos. Yet when we ended treatment, he still had long hair.

What I missed at the time—and what many clinicians still miss—is that our real goal is not just symptom reduction, but increased distress tolerance. We hadn’t addressed the emotional work: learning to sit with the discomfort of being seen, managing the fear of judgment, and accepting the uncertainty of what might happen. Without that foundation, the exposure wasn’t enough.

When Symptom Reduction Leads to Symptom Substitution

We sometimes feel successful when clients become desensitized to a feared stimulus, only to be surprised when another symptom arises in its place. One client I worked with had a longstanding emetophobia (fear of vomiting). She made significant progress in therapy and was eventually able to eat freely and attend social events without fear. But months later, after she became pregnant—a long-hoped-for event—she developed new fears centered on feeling “trapped.”

Her progress hadn’t failed; it had revealed the deeper pattern: a fear of losing control and becoming overwhelmed. Because our earlier work had focused too narrowly on a single symptom, she had to return to therapy and build a new hierarchy around this emerging theme.

A More Accurate Framework: Tolerating Anxiety, Not Eliminating It

The truth is, anxiety is not something we cure—it’s something we learn to live with. Anxiety is a normal human emotion that will come and go across a lifetime. Teaching clients to accept its presence, build cognitive flexibility, and act in alignment with their values despite anxiety is the heart of effective cognitive-behavioral treatment.

One client said it best: “I had the thought, ‘I don’t want to go.’ And I realized it was another anxiety trick. So I walked onto the airplane and buckled my seatbelt anyway. Anxiety isn’t going to stop me from flying.”

That moment wasn’t about desensitization—it was about agency, resilience, and willingness.

The Goal: Building Lifelong Skills and Autonomy

As clinicians, our goal is not to help clients eliminate anxiety, but to become their own best therapists. That includes:

Normalizing anxiety as a part of the human experience.
Teaching clients how to recognize anxiety-driven thoughts and behaviors.
Helping them engage in exposures that promote flexibility, not just symptom relief.
Equipping them with skills that apply across situations, not just within one narrow fear domain.

When we move beyond outdated ideas like desensitization as a standalone goal, we help clients cultivate a more empowered, sustainable relationship with anxiety—one rooted in courage and choice.
