Chapter 15: Obsessive-Compulsive and Related Disorders

Introduction

  • Obsessive–compulsive disorder (OCD) was previously classified as an anxiety disorder.

  • It involves extreme anxiety but differs significantly from other anxiety disorders.

  • OCD and related disorders can be grouped under an obsessive–compulsive spectrum.

Types of Disorders in the Spectrum

  1. Repetitive behaviors
       - Trichotillomania (hair-pulling)
       - Dermatillomania (skin-picking)
       - Onychophagia (nail-biting)

  2. Reward-seeking behaviors
       - Hoarding
       - Kleptomania (compulsive stealing)
       - Pyromania (compulsive fire-setting)
       - Oniomania (compulsive buying)

  3. Disorders related to body appearance or function
       - Body dysmorphic disorder (BDD)

  • Some disorders within this spectrum may not be officially recognized by the American Psychiatric Association (APA).

  • There is ongoing scholarly debate regarding the classification and diagnosis of these disorders.

  • The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, text revision (DSM-5-TR) includes:
      - OCD
      - BDD
      - Hoarding disorder
      - Trichotillomania (hair-pulling)
      - Excoriation (skin-picking)
      - Disorders attributable to substances, medication, or other origins

Learning Objectives

  1. Discuss etiologic theories of OCD.

  2. Describe related compulsive disorders, focusing on self-soothing and reward-seeking behaviors.

  3. Develop a plan of care for clients and families with OCD.

  4. Provide education to clients, families, caregivers, and community members to enhance knowledge and understanding of OCD and related disorders.

  5. Evaluate personal feelings, beliefs, and attitudes regarding OCD and related disorders.

Characteristics of OCD

  • OCD involves recurrent, persistent, intrusive, and unwanted thoughts (obsessions).

  • It also includes ritualistic or repetitive behaviors (compulsions) aimed at eliminating these obsessions or neutralizing associated anxiety.

  • Common rituals include:
      - Checking
      - Counting
      - Washing
      - Praying

  • The disorder may begin in childhood and typically lasts into adulthood.

  • It is a chronic progressive condition, wherein symptoms may wax and wane over time.

  • Related disorders include dermatillomania, trichotillomania, and hoarding.

  • Possible etiological factors encompass genetic influences and environmental experiences.

  • Treatments generally involve medications (particularly SSRIs) and behavioral therapies.

  • Effective nursing interventions consist of therapeutic communication and teaching relaxation techniques.

Severe Symptoms of OCD

  • Clients with severe symptoms require professional treatment and support; they cannot generally alter their patterns of thinking and behavior independently.

  • Stressful periods can exacerbate symptoms.

  • Professionals should provide support without reinforcing the idea that clients can merely alter their behaviors through willpower.

Onset and Clinical Course

  • OCD may onset in childhood, especially among males.

  • For females, onset is more typically noted in the 20s.

  • Generally, onset occurs in late adolescence, with symptoms fluctuating throughout life.

  • The distribution of the disorder is equal across sexes.

  • Clients may experience periods of better functioning with limited symptoms, or conversely, exacerbated symptoms that lead to increased stress.

  • A small percentage of individuals may exhibit complete remission or a progressive deterioration of the disorder's symptoms.

Common Rituals Associated with OCD

Question 1: Which is NOT a common ritual associated with OCD?
A. Checking
B. Counting
C. Washing
D. Praying
E. Exercising

Answer 1: E. Exercising
Rationale: Common rituals associated with OCD include checking, counting, washing, and praying. Exercising is not classified as a ritualistic behavior associated with OCD.

Related Disorders

DSM-5-TR Diagnoses

  1. Excoriation (Dermatillomania)
       - Skin-picking, often common in areas such as the face, fingers, hands, arms, and legs.
       - Helpful treatments may include yoga, acupuncture, and biofeedback.

  2. Trichotillomania
       - Characterized by chronic, repetitive hair pulling, which often begins in childhood and can extend into adulthood.
       - Treatment may involve behavioral therapy, SSRIs, or the antidepressant clomipramine (Anafranil).

  3. Body Dysmorphic Disorder (BDD)
       - Involves preoccupation with imagined physical defects, interfering with daily life functioning.
       - There are overlaps with anxiety, depression, social anxiety disorder, and excoriation disorder.
       - SSRIs may help prevent relapse; however, cosmetic surgery is generally discouraged.

Additional Related Disorders

  1. Hoarding Disorder
       - Involves excessive acquisition of animals or clutter, with living spaces becoming excessively cluttered.
       - The diagnosis has emerged relatively recently and is more common between ages 20 and 30, notably among females.
       - Treatments may include medication, cognitive-behavioral therapy (CBT), and self-help groups.

  2. Onychophagia
       - Chronic nail biting that serves as a self-soothing behavior.
       - Treatments involving SSRIs and CBT are effective.

  3. Kleptomania
       - Characterized by a compulsion to steal for the thrill of not getting caught; there is a lack of standardized treatment.

  4. Oniomania
       - Compulsive purchasing behavior where the reward stems from acquiring rather than using items.
       - Predominantly affects females in their 20s or college students and tends to run in families, often comorbid with depression and substance use.
       - CBT and person-centered therapy may offer assistance.

  5. Body Identity Integrity Disorder (BIID)
       - This disorder includes the need for amputation due to feelings of being "overcomplete" or alienation from specific body parts.
       - Patients may go to extremes, such as packing the limb in dry ice to force a medical professional's hand in approving an amputation.

Etiology

  • The etiology of OCD has been studied from various perspectives, but a definitive explanation for its development remains elusive.

  • Cognitive models of OCD are derived from Beck's cognitive approach to emotional disorders.

  • Individuals with OCD often believe their thoughts are excessively important, exhibiting the belief that, "If I think it, it will happen," and feel a need to control these thoughts.

  • Other contributing factors include
      - Perfectionism
      - Intolerance of uncertainty
      - Inflated sense of personal responsibility (potentially stemming from strict moral or religious upbringing)

  • It is essential to note that environmental influences are not solely responsible for the disorder's development.

Obsessive–Compulsive Spectrum Disorders

Question 2: Which of the following disorders is NOT included in the obsessive–compulsive spectrum according to the DSM-5-TR?
A. Trichotillomania
B. Dermatillomania
C. Onychophagia
D. Pyromania
E. Body dysmorphic disorder (BDD)

Answer 2: D. Pyromania
Rationale: The DSM-5-TR includes OCD, BDD, hoarding disorder, trichotillomania, and excoriation as part of the obsessive–compulsive spectrum but does not classify pyromania (although it is a reward-seeking behavior) within this spectrum.

Cultural Considerations

  • Prevalence rates of OCD are fairly similar or even universal across different countries.

  • Individuals who are highly religious may experience a more intense sense of guilt regarding their symptoms, often feeling responsible for controlling unwanted and threatening thoughts.

  • Prominent feelings of shame and guilt are common among those with OCD.

  • Cultural beliefs may attribute OCD to supernatural causes, with some individuals turning to faith healers for assistance, while others might conceal symptoms rather than seeking professional help.

Treatment

  • Recommended strategies incorporate a combination of medication and behavioral therapy.

Medication Choices

  • SSRI antidepressants such as fluvoxamine (Luvox) and sertraline (Zoloft) are first-line treatments.

  • Venlafaxine (Effexor) serves as a second-line option.

  • Second-generation antipsychotics like risperidone (Risperdal) and aripiprazole (Abilify) may also be prescribed.

  • Behavioral therapy has shown good responses in children and adolescents, especially when combined with SSRIs.

Behavioral Therapy Techniques

  • Exposure Therapy
       - Aims to help the client confront situations and stimuli they generally avoid.

  • Response Therapy
       - Involves delaying or preventing the performance of rituals.

  • A combined methodology utilizing both exposure and response prevention therapy alongside cognitive-behavioral therapy (CBT) has been found to yield better outcomes than using either method alone.

  • For treatment-resistant OCD, somatic therapies targeting neurosurgical lesions in the corticostriatal-thalamic-cortical tracts of the brain may be considered.

Technology-Enhanced Delivery of Treatment

Question 2: Is the statement true or false? Technology-enhanced delivery, such as bibliotherapy and computerized CBT, has become more prevalent due to the COVID-19 pandemic.

Answer: True
Rationale: The COVID-19 pandemic has indeed catalyzed an increase in the utilization of electronic-based treatment options, including bibliotherapy, telephone-delivered CBT, and computerized CBT, as parts of technology-enhanced delivery for managing OCD.

Age-Related Considerations

  • Early-onset OCD (identified by age 10) presents differently than late-onset OCD (median age 19).

  • Early-onset conditions are typically more severe and may correlate with a higher frequency of comorbid diagnoses, alongside a greater likelihood of family history of OCD.

  • Onset of OCD after age 50 is rare, warranting further investigation into possible organic causes (e.g., infections, degenerative disorders, brain injuries, cerebrovascular lesions).

  • Related disorders like trichotillomania, dermatillomania, and onychophagia may have origins in childhood.

  • Hoarding disorder can become evident from around age 11 to 15, often fully manifesting by age 20.

Community-Based Care

  • Clients must utilize exposure and response prevention techniques consistently in the community for extended periods.

  • Regular application of techniques is essential for effective outcomes.

  • Technology-enhanced delivery methods include:
      - Bibliotherapy
      - Telephone-delivered CBT
      - Computerized CBT

  • The COVID-19 pandemic has necessitated large-scale implementation of electronic-based treatment options.

Effective Nursing Interventions for OCD

  • Engage in therapeutic communication to build trust and understanding with the client.

  • Teach relaxation and behavioral techniques to help the client better manage anxiety and stress.

  • Encourage adherence to a daily routine to provide structure and consistency.

  • Educate both clients and families about OCD and its treatment to ensure understanding and support.

  • The practice of anxiety management and behavioral techniques on a daily basis has been highlighted as crucial for fostering positive long-term outcomes.

Summary

  • OCD is characterized by recurrent, persistent, intrusive, and unwanted thoughts (obsessions) along with ritualistic or repetitive behaviors or mental acts (compulsions) performed to alleviate these obsessions or neutralize anxiety.

  • Common compulsions may include various rituals such as checking, counting, washing, scrubbing, praying, chanting, touching, rubbing, and ordering.

  • OCD often begins in childhood and typically continues into adulthood as a chronic progressive disorder, with symptoms varying significantly depending on stress levels.

  • Related disorders to OCD include dermatillomania, trichotillomania, onychophagia, kleptomania, oniomania, BDD, body identity integrity disorder, and hoarding.

  • Effective nursing interventions are imperative and include therapeutic communication, teaching relaxation techniques, following a consistent daily routine, and ensuring client and family education regarding OCD and treatment options.
