Unwanted Intrusive Thoughts
Repetitive thoughts, images or impulses that are unacceptable and/or unwanted. They interrupt an ongoing activity, are attributed to an internal origin, and are difficult to control.
- Rachman (1981)

Clinical Examples of Intrusions
• Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental contamination
• Worry intrusion- unintended occurrence of anticipatory thought related to threat of current concern
• Trauma-related intrusion- sudden reminder of past traumatic experience

Characteristics of Unwanted Intrusive Thoughts
• A distinct identifiable cognitive event
• Unwanted, unintended, & recurrent
• Interrupts the flow of thought
• Interferes in task performance
• Associated with negative affect
• Difficult to control
![Page 5: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/5.jpg)
Unwanted Intrusions: A Nuanced Phenomena
• Strong connection to normality
• Occurrence “trumps” content
• Contextually bound cognitions
• Excessive, irrational, ego-dystonic
• Impervious to effortful control
![Page 6: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/6.jpg)
Normal Intrusions: The Good, the Bad and the Ugly
• 67% of thoughts deal with everyday life concerns (the good)
• 18% of thoughts may be unacceptable and uncomfortable (the bad)
• 13% of thoughts were rated as “out of character” or downright shocking (the ugly)
- Klinger & Cox (1987-1988)

Challenge for Standard CBT & ERP
• Context-driven nature of intrusions
• Misdirected focus on intrusion content rather than process
• High distress intolerance
• Poor homework compliance
![Page 8: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/8.jpg)
Treating Intrusions: Three Facets
• Context (triggers)
• Metacognition (appraisals)
• Mental Control
![Page 9: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/9.jpg)
UIT Context Assessment and Treatment
![Page 10: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/10.jpg)
Triggers & Context:
Internal/external origins, spontaneous &
unintended
![Page 11: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/11.jpg)
Assessing UITs
• Retrospective self-report questionnaires
• Daily self-monitoring
• “Symptom” provocation
• Imaginal & role play simulation
• Electronic cueing (??)
![Page 12: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/12.jpg)
Treatment: Normalization
• Refocus psychoeducation (appraisal not content)
• Select a “normal” intrusion
• “toxify” a nonrecurrent, negative thought
• Select the problematic UIT
• Develop “de-toxification” plan
![Page 13: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/13.jpg)
UIT Appraisal Treatment
Considerations
![Page 14: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/14.jpg)
Metacognition & Intrusions
Metacognitive knowledge refers to
the beliefs and theories people have
about their thinking, whereas
metacognitive experiences are the
context-specific appraisals and
feelings individuals have of their
mental status.
- Wells (2009) Metacognitive Theory
for Anxiety and Depression
![Page 15: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/15.jpg)
Faulty Appraisals & Intrusions
•Overestimated Threat
• Intolerance of Uncertainty
• Inflated Responsibility
•Overimportance of Thoughts
•Need for Mental Control
•Emotional Reasoning
![Page 16: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/16.jpg)
Cognitive Restructuring of Appraisal Beliefs • Focus on real-life intrusion experiences
(appraisals gone wrong)
• Identify faulty evaluative process and underlying belief
• Use evidence gathering and consequences to challenge belief
• Generate alternative “benign” evaluation
• Obtain experiential evidence of “catastrophic” vs. “benign” interpretation

Pathological Mental Control- Clinical Illustration
Thinking About
Breathing
Mental Control Effort
Appraisals of Control
Failure
Intrusions increase;
inability to distract;
heightened anxiety
![Page 19: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/19.jpg)
Mental Control Strategies
• Cognitive distraction or thought replacement
• Rationalization and self-reassurance
• Self-criticism or punishment
• Reassurance seeking from others
• Thought stopping
• Behavioral distraction
• Attentive thinking, analyzing the thought
• Cognitive restructuring
• Do nothing
![Page 20: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/20.jpg)
Relinquishing Control
• Demonstrate futility of control (“white bear”)
• Introduce overt & covert response prevention
• Practice intentional mental exposure (“thought satiation”)
• Capitalize on spontaneous intrusions (situational exposure)
• Distance; nonjudgmental acceptance
![Page 21: Unwanted Mental Intrusions in Anxiety Disorders 006 - Clark.pdf · Clinical Examples of Intrusions •Obsessional intrusion- repugnant aggressive, sexual, religious thoughts, mental](https://reader031.fdocuments.net/reader031/viewer/2022020303/5af57b987f8b9a9e598e1c06/html5/thumbnails/21.jpg)
Summary
• Strange thoughts are normal, safe
• Meaning modulates emotion
• Effortful control is counterproductive
• Observe, accept, distract
