Anxiety: Exploring the Effectiveness of Exposure Therapy
Exposure-based therapy is a highly effective treatment for anxiety disorders, including generalised anxiety disorder. However, its application remains significantly underutilised, underscoring the need for greater dissemination and specialised training in this therapeutic approach.
Prevalence of Panic Disorder
Anxiety disorders are among the most prevalent mental health conditions, with over a quarter of individuals in the United States experiencing such issues at some point in their lives. Despite the robust evidence supporting exposure-based behavioural therapies as an effective intervention, only a small proportion of patients receive this form of treatment.
For instance, data from the Harvard/Brown Anxiety Research Project indicate that just 23% of treated individuals reported receiving regular imaginal exposure, and only 19% had access to occasional in vivo exposure.
What is Exposure Therapy?
How Exposure Therapy Works
Exposure therapy begins with a therapist gaining a thorough understanding of your fears and anxieties through detailed discussions. This initial assessment helps the therapist create a personalised plan for your exposure therapy. The specifics of your treatment will depend on the type of exposure therapy used and the particular fear or anxiety you are addressing.
The process involves confronting the feared object, situation, or activity and staying in contact with it until the anxiety diminishes. This can be done in the therapist’s office or as homework assignments to be completed independently. The gradual exposure helps desensitise you to the fear, making it more manageable over time. The key is to remain in the feared situation until the anxiety naturally decreases, reinforcing the idea that the fear is not as threatening as initially perceived.
Barriers to Utilisation
Several factors contribute to the underutilisation of exposure-based therapies:
-
Lack of Specialist Training: Many mental health clinicians do not receive adequate training to perform exposure therapy, limiting their ability to deliver this treatment effectively.
-
Misconceptions Among Clinicians: Some practitioners harbour unfounded concerns about exposure therapy, fearing it may exacerbate symptoms. This misconception is widespread among psychologists working with PTSD patients.
-
Preference for Alternative Treatments: Surveys reveal that many clinicians favour other therapeutic approaches to overexposure therapy despite evidence suggesting that patients often prefer exposure-based methods.
Evidence Supporting Virtual Reality Exposure Therapy
Contrary to concerns, research consistently shows that exposure-based therapy does not worsen symptoms or lead to higher treatment dropout rates. Prolonged exposure, a specific type of exposure-based therapy, has been shown to be particularly effective in clinical studies for PTSD. On the contrary, it is associated with significant improvements in both symptoms and overall functioning, particularly for individuals with PTSD.
Studies also suggest that patients with trauma histories or PTSD often express a preference for exposure-based interventions over alternative treatments. This highlights the importance of addressing clinician misconceptions to align therapeutic offerings with patient preferences and evidence-based practices.
Performing Exposure Therapy
Performing exposure therapy involves a structured approach to help individuals systematically confront and overcome their fears and anxieties. The first step is identifying the specific feared object, situation, or activity and creating a hierarchy of feared stimuli, ranking them from least to most anxiety-provoking.
Starting with the least feared item on the list, the individual gradually increases the intensity of the exposure. Using a timer to track exposure duration and practising relaxation techniques, such as deep breathing or progressive muscle relaxation, can help manage anxiety during the process. This methodical approach ensures that the individual can handle each step without becoming overwhelmed.
Exposure therapy can be conducted with the guidance of a therapist or counsellor or independently using self-help resources. The key is to maintain consistency and gradually increase exposure to more challenging stimuli, ultimately reducing the overall anxiety associated with the fear.
Call for Action
The research underscores the necessity of prioritising exposure-based therapy as a first-line treatment for various anxiety disorders. Systematic desensitisation, a type of exposure therapy, is particularly effective in reducing anxiety and avoidance over time by gradually introducing clients to fear-inducing stimuli while employing relaxation techniques to manage their fear response. Enhancing access to specialist training for clinicians and addressing misconceptions about exposure therapy are critical steps in bridging the gap between research evidence and clinical practice.
Conclusion
Exposure-based therapy offers a powerful and evidence-backed solution for treating anxiety disorders. Virtual reality exposure immerses patients in a simulated environment to confront their fears, employing advanced technology to create realistic scenarios that allow them to engage with their fears in a controlled and safe manner. By expanding training opportunities and fostering awareness among clinicians, this effective therapeutic approach can be more widely utilised to improve outcomes for individuals with anxiety disorders. Virtual reality exposure therapy serves as an effective alternative to traditional imaginal exposure, allowing patients to confront their fears in a controlled virtual environment.
