Anxiety is a physiological, behavioral and psychological reaction all at once
Therefore intervention programs in general should focus on:
- to reduce physiological reactivity- to eliminate avoidance behavior - to change subjective reaction

Anticipatory anxiety is closely associated with the way you are thinking.
With panic disorder, thoughts are generally focused on worrying about having a panic attack in a situation that will result in embarrassment, extreme discomfort, a heart attack or even worse.

The panic doesn’t occur because you are thinking about, approaching or actually entering a phobic situation
It happens spontaneously and unexpectedly for no apparent reason

Agoraphobia The word agoraphobia means fear of open

Obsessive Compulsive Disorder
Obsessions are recurring ideas, thoughts, images or impulses

Obsessions may occur by themselves without necessarily being accompanied by compulsions

Post Traumatic Stress Disorder
The essential feature of post traumatic stress disorder is the development of disabling psychological symptoms following a traumatic event
The traumatic event involves either actual or threatened death or serious physical injury or threat to one’s own or another’s physical safety
22
![Page 23: TOPIC 5 ANXIETY DISORDERS](https://reader035.vdocument.in/reader035/viewer/2022062501/56816462550346895dd641c3/html5/thumbnails/23.jpg)
Symptoms of PTSD
Repetitive, distressing thoughts about the event Nightmares related to the event Flashbacks so intense that you feel or act as though the trauma
were occurring all over again An attempt to avoid thoughts or feelings associated with the
trauma An attempt to avoid activities or external situations associated
with the trauma Emotional numbness Feeling of detachment or estrangement from others Losing interest in activities that used to give you pleasure Persistent symptoms of increased anxiety, such as difficulty
falling or staying asleep, difficulty concentrating
23
![Page 24: TOPIC 5 ANXIETY DISORDERS](https://reader035.vdocument.in/reader035/viewer/2022062501/56816462550346895dd641c3/html5/thumbnails/24.jpg)
To receive a diagnosis of PTSD, these symptoms need to have persisted at least 1 month
Less than 1 month’s duration, the appropriate diagnosis is “acute stress disorder”
In addition, the disturbance must be causing you significant distress, interfering with social, vocational or other important areas of your life

Theoretical Perspectives Psychodynamic perspective
- anxiety disorders are viewed as neurosis- the anxiety experienced in neurosis reflects;
1 – the efforts of unacceptable, repressed impulses to break into consciousness
2 – fear as what might happen if they do
Stress on the roles of defense mechanisms
25
![Page 26: TOPIC 5 ANXIETY DISORDERS](https://reader035.vdocument.in/reader035/viewer/2022062501/56816462550346895dd641c3/html5/thumbnails/26.jpg)
Phobias develop through the use of defense mechanism of projection and displacement
A phobic reaction is believed to represent the projection of the person’s own threatening impulses onto the phobic object.

Learning Perspectives
Anxiety disorders are acquired through conditioning
Phobia - Classical conditioning- Operant conditioning - Observational learning – modeling
27
![Page 28: TOPIC 5 ANXIETY DISORDERS](https://reader035.vdocument.in/reader035/viewer/2022062501/56816462550346895dd641c3/html5/thumbnails/28.jpg)
Generalized anxiety- a product of stimulus generalization
Obsessive compulsive disorder- compulsive behavior are operant responses that are negatively reinforced by relief of the anxiety that is engendered by obsessional thoughts
PTSD - classical conditioning 28

The specific treatment approach depends on the type of anxiety disorder and its severity. But in general, most anxiety disorders are treated with cognitive-behavioral therapy, medication, or some combination of the two.

SYSTEMATIC DESENSITIZATION
Systematic desensitization is a technique which is used to help people manage and eventually conquer phobias
An individual learn to handle progressively more disturbing stimuli while they remain relaxed
About 10 – 20 stimuli are arranged in a hierarchy (fear stimulus hierarchy)
33
![Page 34: TOPIC 5 ANXIETY DISORDERS](https://reader035.vdocument.in/reader035/viewer/2022062501/56816462550346895dd641c3/html5/thumbnails/34.jpg)
Assumption (Joseph Wolpe, 1958) – maladaptive anxiety responses, like other behaviors are learned or conditioned. They can be unlearned by conterconditioning.
Advantages of systematic desensitization are:- enhance self-efficacy expectancies- lower catecholamine levels- help people overcome phobias through a stepwise approach of actual exposure to the phobic stimuli

The procedures of systematic desensitization
1. Begins with the collection of a history of the patient’s problem
2. The problem is explained to the patient3. Explain the rationale of systematic
desensitization4. Train the patient with relaxation
techniques5. Establish an anxiety hierarchy6. Imagery desensitization

Cognitive Techniques
Rational restructuring Much maladaptive behavior is determined by the assumptions people make about the world
In this rational restructuring, argument or discussion may be used in an attempt to get patients to see the irrationality of their belief
The therapist may attempt to teach them to modify their internal sentences

Complementary treatments for anxiety disorders Exercise – Exercise is a natural stress buster and anxiety reliever.
Research shows that as little as 30 minutes of exercise three to five times a week can provide significant anxiety relief. To achieve the maximum benefit, aim for at least an hour of aerobic exercise on most days.
Relaxation techniques – When practiced regularly, relaxation techniques such as mindfulness meditation, progressive muscle relaxation, controlled breathing, and visualization can reduce anxiety and increase feelings of relaxation and emotional well-being.
Biofeedback – Using sensors that measure specific physiological functions—such as heart rate, breathing, and muscle tension—biofeedback teaches you to recognize the body’s anxiety response and learn how to control them using relaxation techniques.
Hypnosis – Hypnosis is sometimes used in combination with cognitive-behavioral therapy for anxiety. While you’re in a state of deep relaxation, the hypnotherapist uses different therapeutic techniques to help you face your fears and look at them in new ways.
