How ERP Works for Phobias Like Fear of Flying: Scientific Insights and the Role of ACT
Phobias are among the most common anxiety disorders, affecting millions worldwide. One of the most prevalent is aviophobia, or the fear of flying. For those who experience this phobia, the thought of boarding a plane can trigger intense anxiety, panic attacks, and avoidance behaviors that disrupt personal and professional life. Fortunately, evidence-based psychological treatments offer hope. Two of the most scientifically validated approaches are Exposure and Response Prevention (ERP) and Acceptance and Commitment Therapy (ACT). In this comprehensive blog post, we’ll explore how ERP works for phobias such as fear of flying, delve into the scientific principles behind ERP and ACT, and discuss how these therapies can be integrated for optimal outcomes.
Understanding Phobias: The Case of Fear of Flying
Phobias are characterized by persistent, excessive, and irrational fears of specific objects or situations. In the case of aviophobia, individuals may fear the plane crashing, losing control, experiencing panic attacks mid-flight, or being unable to escape. These fears often lead to avoidance—canceling trips, refusing to fly, or enduring flights with extreme distress.
Phobias are maintained by a cycle of avoidance and negative reinforcement. When a person avoids flying, their anxiety decreases temporarily, reinforcing the avoidance behavior. Over time, this cycle strengthens the phobia, making it harder to overcome.
What is Exposure and Response Prevention (ERP)?
ERP is a form of cognitive-behavioral therapy (CBT) that is highly effective for treating anxiety disorders, including phobias. ERP is based on the principle of exposure—gradually and systematically confronting the feared object or situation—and response prevention—refraining from engaging in avoidance or safety behaviors.
The Science Behind ERP
ERP is grounded in the psychological concept of habituation and extinction learning. When individuals are repeatedly exposed to a feared stimulus without the anticipated negative outcome, their anxiety diminishes over time. This process is called habituation. Extinction learning refers to the weakening of the association between the stimulus (e.g., flying) and the fear response.
Key Steps in ERP for Phobias
Assessment and Hierarchy Development:
The therapist works with the client to identify specific fears and avoidance behaviors. Together, they create an exposure hierarchy—a list of feared situations ranked from least to most anxiety-provoking (e.g., looking at pictures of planes, visiting an airport, sitting in a stationary plane, taking a short flight).Gradual Exposure:
The client is systematically exposed to items on the hierarchy, starting with the least distressing. For fear of flying, initial exposures might involve reading about flying, watching videos, or visiting an airport.Response Prevention:
During exposure, the client is encouraged to refrain from safety behaviors (e.g., taking sedatives, constantly checking flight statistics, seeking reassurance). This allows anxiety to rise and fall naturally, promoting habituation.Processing and Reflection:
After each exposure, the therapist and client discuss the experience, focusing on changes in anxiety and challenging catastrophic beliefs.Generalization and Maintenance:
The client practices exposures in various contexts to ensure the gains are maintained and generalized to real-life situations.
ERP in Action: Treating Fear of Flying
Let’s consider a typical ERP protocol for aviophobia:
Session 1-2: Psychoeducation about anxiety, phobias, and ERP. Development of the exposure hierarchy.
Session 3-5: Imaginal exposure—visualizing flying scenarios, reading stories about flights.
Session 6-8: In vivo exposure—visiting the airport, sitting in a stationary plane.
Session 9-12: Actual flight exposure—booking a short flight, flying with the therapist or a support person.
Throughout the process, the client learns that anxiety, while uncomfortable, is not dangerous and will decrease with repeated exposure. They also learn to tolerate uncertainty and relinquish safety behaviors.
Scientific Evidence for ERP
Numerous studies have demonstrated the efficacy of ERP for phobias. Meta-analyses show that ERP leads to significant reductions in phobic avoidance and anxiety, with effects maintained over time. For fear of flying, ERP has been shown to increase flight frequency and reduce distress during flights.
A landmark study by Oakes and Bor (2010) found that individuals with aviophobia who underwent ERP reported significant improvements in their ability to fly and reduced anxiety compared to control groups. ERP is considered the gold standard for specific phobias by organizations such as the American Psychological Association.
Acceptance and Commitment Therapy (ACT): A Modern Approach to Phobias
While ERP focuses on changing behavior through exposure, Acceptance and Commitment Therapy (ACT) takes a different approach. ACT is a third-wave behavioral therapy that emphasizes acceptance, mindfulness, and values-based action.
The Science Behind ACT
ACT is based on Relational Frame Theory (RFT), which posits that language and cognition can create psychological suffering. In phobias, individuals become entangled with fearful thoughts and feelings, leading to avoidance.
ACT teaches clients to:
Accept uncomfortable thoughts and feelings rather than fighting them.
Defuse from unhelpful thoughts—seeing them as mental events, not truths.
Focus on the present moment through mindfulness.
Clarify personal values—what matters most in life.
Commit to action aligned with values, even in the presence of anxiety.
ACT in Action: Treating Fear of Flying
An ACT protocol for aviophobia might include:
Mindfulness exercises to observe anxiety without judgment.
Cognitive defusion techniques (e.g., repeating the word “plane” until it loses meaning) to reduce the power of fearful thoughts.
Values clarification—exploring why flying is important (e.g., visiting family, career opportunities).
Committed action—taking steps toward flying, even if anxiety is present.
ACT does not aim to eliminate anxiety but to change the client’s relationship with it. The goal is psychological flexibility—the ability to act in accordance with values, even when anxious.
Scientific Evidence for ACT
Research supports ACT as an effective treatment for anxiety disorders, including phobias. A meta-analysis by A-Tjak et al. (2015) found that ACT is as effective as traditional CBT for anxiety and depression. Studies specifically on phobias show that ACT can reduce avoidance and increase willingness to face feared situations.
For fear of flying, ACT helps clients accept the possibility of anxiety during flights and focus on the meaningful reasons for flying. This reduces avoidance and increases engagement in life.
ERP vs. ACT: Complementary Approaches
ERP and ACT are both evidence-based, but they differ in focus:
ERP targets behavioral change through exposure and habituation.
ACT targets psychological flexibility through acceptance and values.
Recent research suggests that combining ERP and ACT can enhance outcomes. For example, ACT principles can help clients tolerate the discomfort of exposure in ERP, making it easier to complete exposures. Conversely, ERP provides a structured way to face fears, which complements ACT’s emphasis on values-based action.
Integrating ERP and ACT for Fear of Flying
A combined protocol might look like this:
Psychoeducation:
Teach clients about anxiety, phobias, ERP, and ACT principles.Values Clarification:
Explore why flying is important and how avoidance impacts life.Mindfulness Training:
Practice observing anxiety during exposures without judgment.Exposure Hierarchy:
Develop and implement graded exposures, using ACT techniques to accept discomfort.Defusion Exercises:
Use ACT strategies to reduce the impact of catastrophic thoughts during exposures.Committed Action:
Encourage clients to take flights in service of their values, even if anxiety persists.
This integrative approach leverages the strengths of both therapies, promoting lasting change.
