Anxiety Disorders
Foundational Concepts of Anxiety in Occupational Therapy
The treatment of anxiety within occupational therapy is guided by two primary conceptual pillars: "fear focused" and "face your fear."
While numerous distinct anxiety disorders exist, they share a singular commonality: significant fear that impacts an individual's behavior.
This commonality allows practitioners to address various conditions under one conceptual umbrella rather than attempting to memorize every specific condition as an isolated entity.
Anxiety stems fundamentally from fear, which creates substantial barriers to engaging in everyday activities.
Impacted areas of occupation include:
Social activities with friends and family.
Activities of Daily Living (ADLs).
Leisure activities.
Work performance.
Clinical Manifestations and Functional Impact of Anxiety
Anxiety presents through various behavioral and cognitive patterns that interfere with life roles:
Social Anxiety: May manifest as a client keeping their eyes down and avoiding eye contact.
Performance Anxiety: Seen in students who are terrified of looking foolish or sounding irrational during presentations.
Fear of Failure: Can result in task avoidance, such as a student repeatedly pushing off an exam because they did not achieve their desired score previously.
Specific types of anxiety disorders and their characteristics include:
Panic Disorder: Characterized by repeated and unexpected panic attacks. Symptoms include shortness of breath, a rapid heart rate, dizziness, and nausea. Individuals often develop a "fear of the fear response," becoming anxious about the experience of anxiety itself.
Phobias: An intense fear of a specific stimulus, such as spiders, heights, or large crowds.
Post-Traumatic Stress Disorder (PTSD): Triggered by a stressful past event, leading to repeated anxiety events that cause the individual to experience that distress in the current moment.
Obsessive-Compulsive Disorder (OCD): Consists of obsessions (persistent thoughts) and time-consuming compulsions (behaviors) that interfere with normal life. It is categorized as an anxiety disorder because the client feels an internal demand to perform tasks in a specific manner; failure to do so results in extreme anxiety.
Therapeutic Intervention Pathway: Facing Your Fear
The goal of these interventions is to help clients address the problem of fear head-on to develop adaptive responses.
Cognitive Behavioral Therapy (CBT):
Focuses on helping clients confront irrational fears or thoughts.
Assists clients in recognizing that they have survived previous physiological, cognitive, and emotional experiences without catastrophe.
Encourages problem-solving to determine how to respond to irrational fears rather than withdrawing from social situations or ADLs.
Exposure Therapy and Desensitization:
Functions by weakening the fear through gradual and safe engagement with the fearful stimulus.
Eye Movement Desensitization and Reprocessing (EMDR):
Uses specific eye movements while the client thinks about fearful stimuli to reprocess those experiences as non-threatening.
Interpersonal Training (Social Skills Training):
Teaches clients how to socialize and address social anxiety directly.
Employs the principle of grading to prevent exacerbating anxiety. For example, if a client is isolating due to social anxiety, the therapist would not suggest attending a high-stimulus environment like a concert. Instead, the task is graded down to a lower social demand, such as meeting one friend for coffee in a small, quiet shop to ensure a safe and supportive environment.
Therapeutic Intervention Pathway: Relaxing and Reducing Fear
This pathway focuses on reducing the heightened state of arousal through relaxation methods.
Relaxation Training:
Includes mindfulness and guided meditation.
Visualization: Encouraging the client to imagine positive, calming scenes, such as listening to waves crashing on a beach.
Deep Breathing: An effective method for physiological regulation.
Autogenic Training:
involves teaching the client "silent self-talk" to manage anxiety in the moment. Examples include internal affirmations such as "I got this," "I can do this," or "I am capable."
Biofeedback:
A method where clients monitor biological states that are typically involuntary, such as heart rate, blood pressure, and temperature.
By using a heart monitor while discussing fearful experiences and simultaneously engaging in deep breathing, clients learn to actively lower their heart rate and gain control over physiological responses.
Complementary Frames of Reference and Management Strategies
Psychodynamic Frame of Reference:
Utilizes creative self-expression to release fearful or irrational thoughts.
Activities include writing, arts and crafts, photography, and journaling.
The objective is to clear mental space occupied by anxious thoughts to make room for positive thoughts and daily engagement.
Time Management and Task Modification:
Helps clients who become overwhelmed by everyday activities.
Break down tasks into smaller, achievable steps.
Incorporate schedules and to-do lists to provide the client with a sense of control.
Examples of grading tasks: If a client is anxious about grocery shopping, the task is graded so they only purchase items rather than a full week's worth of groceries, reducing the risk of an overwhelming anxiety response.
Clinical Reasoning and Strategy Mnemonic
To remember the two main approaches to treating anxiety, use the phrase: "Take a deep breath and face your fear."
"Take a deep breath" represents general relaxation strategies (visualization, deep breathing, autogenic talk) to reduce arousal and improve functional state.
"Face your fear" represents addressing the problem directly through CBT or exposure therapy to reduce the long-term impact of the fear stimulus.
Case Studies and Clinical Discussion
Case Study 1: An electrician reports becoming panicky when working on roofs, experiencing a rapid heartbeat, trembling, shortness of breath, and feelings of suffocation.
Correct Action: The therapist should educate the client on abdominal breathing prior to and while on the roof.
Rationale: This is a direct occupational therapy intervention utilizing relaxation strategies. Referring to a physician for heart medication or beta-blockers is not the primary OT response.
Case Study 2: An OT is planning a social skills group for individuals with anxiety. A group member is painfully shy and sits alone. The OT suggests the member attend multiple sessions and observe for before being asked to participate in the task group.
Behavioral Strategy: This is an example of desensitization.
Rationale: The strategy allows the client to sit in a social environment without the pressure of participation, allowing the initial stress response to decrease before engagement begins.
Case Study 3: A client with OCD is fearful of germs and scrubs their hands times per day for approximately each time. The client avoids public places, leading to social alienation. The therapist implements an exposure and response program.
Initial Objective: To slowly and systematically expose the client to the feared stimulus.
Rationale: This aligns with the "face your fear" approach, helping the client realize that the expected catastrophe does not occur if they refrain from performing their compulsions.
Case Study 4: An individual with agoraphobia is making progress and is increasingly able to leave the house. Previous sessions focused on anxiety management and relaxation.
Next Steps: The therapist should work on finding new and enjoyable ways for the client to spend time.
Rationale: Since the client is meeting the goal of leaving the house, the next clinical priority is finding meaningful, comfortable activities to engage in outside the home. While psychodynamic expression (expressing emotion) is a valid tool, finding enjoyable ways to spend time is the logical step for community reintegration.
