Study Notes on Anxiety and Anxiety Disorders

Anxiety & Anxiety Disorders

Overview of Anxiety Disorders

  • Etiology: Factors contributing to anxiety disorders include biological, genetic, neurochemical, psychodynamic, interpersonal, and behavioral theories.

    • Biologic Theories: Explore physiological components of anxiety.

    • Genetic Theories: Suggest a hereditary link to anxiety disorders.

    • Neurochemical Theories: Focus on neurotransmitters such as GABA and serotonin involved in anxiety regulation.

    • Psychodynamic Theories: Investigate internal conflicts influencing anxiety, particularly emphasizing Freud and defense mechanisms.

    • Interpersonal Theories: Discuss the contributions of theorists like Sullivan and Peplau on social interactions related to anxiety.

    • Behavioral Theory: Examines learned behaviors as a basis for anxiety.

Definition of Anxiety

  • Anxiety is characterized as a vague feeling of dread or apprehension.

  • Distinction from fear:

    • Fear is an emotional response to a real and immediate threat, involving identifiable stimuli that signify danger.

  • Anxiety is differentiated by excessive anxiety accompanied by behavioral, emotional, cognitive, and physiological responses.

Anxiety as a Response to Stress

  • Stress: Refers to the wear and tear that life exerts on the body.

  • General Adaptation Syndrome: A three-stage physiological response to stress identified by Hans Selye:

    • Alarm Reaction Stage: Body prepares for defense against perceived threats.

    • Resistance Stage: Blood is redirected to areas necessary for defense, maintaining homeostasis.

    • Exhaustion Stage: Resources are depleted, leading to unresolved emotional components.

Levels of Anxiety

  • Mild Anxiety:

    • Involves mild tension and heightened sensory awareness, serving a motivational role.

  • Moderate Anxiety:

    • Sensation of something being wrong with feelings of nervousness or agitation, alongside concentration difficulties; however, individuals can be redirected.

  • Severe Anxiety:

    • Characterized by a continuous struggle to think clearly, tightened muscles, and increased vital signs; may lead to irritability or anger.

  • Panic:

    • Involves an acute fight, flight, or freeze response, featuring heightened vital signs and cognitive processes focused on defense mechanisms.

Working with Anxious Clients

  • Develop self-awareness of one's anxiety levels.

  • Assess the client's anxiety levels in a nonthreatening manner.

  • Communicate using short, simple sentences for clarity.

  • Aim to lower the client’s anxiety to moderate or mild before progressing with treatment.

  • Utilize a low, calm, and soothing voice.

  • Prioritize safety when a client is in panic.

  • Create a small, quiet, and non-stimulating environment.

  • Consider short-term anxiolytics for immediate relief (refer to Table 14.2).

Overview of Anxiety Disorders

  • Key types include:

    • Agoraphobia

    • Panic Disorder

    • Specific Phobia

    • Social Anxiety Disorder (Social Phobia)

    • Generalized Anxiety Disorder (GAD)

Related Disorders

  • Generalized Anxiety Disorder (GAD): Characterized as chronic, lasting longer than six months. Treatment typically includes buspirone and SSRIs.

  • Selective Mutism: A condition where a child cannot speak in specific social situations despite speaking in others.

  • Anxiety Disorder Due to Another Medical Condition: Anxiety as a direct result of an existing medical condition.

  • Substance/Medication-Induced Anxiety Disorder: Anxiety that emerges due to toxin exposure or drug abuse.

  • Separation Anxiety Disorder: Involves excessive fear or anxiety concerning separation from attachment figures.

Statistics on Anxiety Disorders

  • Anxiety disorders are the most common psychiatric disorders in the United States.

  • Prevalence is higher among:

    • Women

    • Individuals under 45 years old

    • Those who are divorced or separated

    • Individuals of lower socioeconomic status.

  • Onset and progression can vary widely.

Treatment Strategies

  • Effective treatment usually combines medications and therapy.

  • Common medications include:

    • Antidepressants

  • Therapeutic strategies include:

    • Cognitive–Behavioral Therapy (CBT)

    • Positive Reframing: Transforming negative thoughts into positive perspectives.

    • Decatastrophizing: Aiming for a more realistic appraisal of situations.

    • Assertiveness Training: Training to negotiate social interactions effectively.

Elder Considerations

  • Late-Life Anxiety Disorders: Commonly present as phobias (especially agoraphobia and GAD) and involve panic attacks that are less frequent and often linked to other medical conditions.

  • Features may include ruminative thoughts, intrusive fears of contamination, or fear of harming others.

  • These issues are frequently co-morbid with conditions like depression, dementia, or physical illness.

  • SSRIs are regarded as the first-line treatment for anxiety in the elderly. A traditional approach is to start low and increase dosing slowly.

Mental Health Promotion

  • Anxiety serves as a signal indicating ineffective stress management.

  • Positive events can also lead to stress.

  • The goal is to manage anxiety effectively rather than eliminate it completely, recognizing the role medication plays in relief but not in solving anxiety altogether.

Tips for Managing Stress

  • Cultivate a positive attitude and a strong belief in self.

  • Accept that some events are beyond control.

  • Engage in assertive communication and express feelings, whether through talking, laughing, or crying.

  • Set realistic goals and partake in personally meaningful activities.

  • Maintain a well-balanced diet, adequate exercise, and proper rest/sleep.

  • Employ various techniques for stress management.

Panic Disorder

  • Defined by discrete episodes of panic attacks that frequently lack a specific stimulus (75% of the time).

  • Diagnosed when recurrent, unexpected attacks are followed by a minimum of one month of worry concerning future attacks.

  • Agoraphobia is present in approximately half of individuals with panic disorder.

  • Increased risk of suicidality and avoidance behaviors can occur, highlighting both primary and secondary gains related to disorder reinforcement.

  • Treatment Options include:

    • Cognitive–behavioral techniques

    • Deep breathing exercises and relaxation techniques

    • Medications: benzodiazepines, SSRIs, tricyclic antidepressants,
      antihypertensives (e.g., clonidine, propranolol).

Panic Disorder and Nursing Process Application

Assessment Steps

  • Utilize tools such as the Hamilton Rating Scale for Anxiety (refer to Box 14.1).

  • Evaluate patient history and clinical observations:

    • General appearance and motor behavior (e.g., automatisms)

    • Mood, affect, and cognitive processes (e.g., feelings of depersonalization or derealization).

    • Self-concept: Look for patterns of self-blame or worry.

    • Monitor physiological and self-care issues, including sleep and eating patterns.

Nursing Diagnoses and Interventions

  • Establish nursing diagnoses followed by outcome identification.

  • Implement interventions that focus on:

    • Ensuring safety and comfort

    • Therapeutic communication to manage anxiety

    • Providing education to clients and families

  • Continually evaluate the effectiveness of treatment strategies.

Phobias

Definition and Types

  • Phobias are defined as intense, illogical, and persistent fears of specific objects or situations, with responses often disproportionate to actual threat levels.

  • Major categories include:

    • Agoraphobia: Fear of open or crowded spaces.

    • Specific Phobia: Various categories include natural environment (e.g., heights), blood-injection-injury, situational (e.g., flying), animal (e.g., spiders), and other specific types.

Treatments for Phobias

  • Common treatment options include:

    • Behavioral therapy, including techniques such as positive reframing and assertiveness training, systematic desensitization, and flooding.

    • Medications should be referenced as per Table 14.3.

Self-Awareness Issues in Anxiety and Stress Management

  • Nurses and caregivers should understand their own vulnerabilities to stress and anxiety.

  • Recognize that everyone experiences stress and anxiety at some point.

  • Avoid attempting to "fix" clients' anxiety problems directly and prioritize using personal techniques to manage stress and anxiety effectively.
