Introduction to Concepts, Terms, and Tools

How writing your worst-case scenarios and facing your fears can reduce anxiety, depression, stress and emotional discomfort.

Section one

Key Concepts and Terms

As you read and respond to the exercises in this workbook, the following terms and concepts may provide helpful explanations to round out your knowledge or aid your understanding.

26 terms
Anxiety
A self-protective response to a physical or psychological threat. Physical symptoms of anxiety can include an increase in heart rate and respiration, sweaty palms, dry mouth, butterflies in one's stomach, or dizziness. Anxiety is often referred to as the fight or flight response.
Obsessions
Unwelcome and distressing ideas, thoughts, images or impulses that repeatedly enter one's mind. They may seem to occur against one's will. They may be repugnant, be recognized as senseless, and not fit one's personality.
Compulsions
Behaviors or acts that one feels driven to perform, though they may be recognized as senseless or excessive. At times, it may prove difficult to resist doing them. An individual might experience anxiety that does not diminish until the behavior is completed.
Exposure and Response PreventionERP
Empirically proven treatment of anxiety disorders, including OCD, where the individual is exposed to the anxiety-producing stimulus and asked to resist compulsive or safety behaviors. Exposure exercises help desensitize people to triggers, including intrusive thoughts, as the participant learns that thoughts are just thoughts. Clients are encouraged to practice exposure every day during treatment and to continue to practice after treatment to help inoculate against relapse.
Safety / Avoidance Behaviors
Any behavior done in order to reduce anxiety. This may include avoiding certain situations or events, taking medication to reduce the physical symptoms of anxiety, engaging in compulsive behaviors, and seeking reassurance from loved ones.
Subjective Units of DiscomfortSUD
A rating scale (1–10) used to describe the intensity of anxiety or emotional discomfort, where 1 represents minimal discomfort or anxiety, and 10 is the maximum the individual can imagine.
Dimensional OCD Scale (DOCS), Y-BOCS (Yale-Brown Obsessive-Compulsive Scale) or (C)Y-BOCS (Children’s Yale-Brown Obsessive-Compulsive Scale)
These self-assessment and interview tools are used to help diagnose OCD in adults and children and are used in building hierarchies.
Hierarchy
A list of triggers compiled and ranked for the purpose of planning exposure. The triggers are selected from the Y-BOCS or (C)Y-BOCS, or may be drawn from stress logs, in-session content, and homework. The items are then rated using the SUD scale from easiest to most difficult.
Imaginal Exposure
Using the imagination to expose oneself to anxiety-producing thoughts, ideas, images, or situations.
Intrusive Thoughts
Sudden, unwanted thoughts or images that pop into your mind and feel disturbing, odd, or out of character. Almost everyone has intrusive thoughts at times, including people without anxiety disorders. What makes them a problem is not that they appeared, but the meaning you attach to them (“Having this thought must mean I am dangerous/evil”) and the behaviors that follow (compulsions, checking, avoidance, reassurance-seeking). In this workbook, you will learn to notice intrusive thoughts, name them for what they are, and practice responding without rituals or avoidance.
In Vivo Exposure
Exposing oneself to anxiety-producing thoughts, ideas, images, or situations in real life. As individuals go through the day, they may encounter and choose to confront an anxiety-provoking situation directly, or they may create a situation in which they can practice prolonged exposure.
Worst Case Scenario
A story or narrative someone writes to imagine, not only being exposed to the anxiety-producing stimuli but also what they fear might happen because of the exposure. This exposure exercise is used in imaginal exposure.
Trigger
Anything that causes an increase in anxiety. Triggers can be events, people, places, situations, thoughts, words, colors, numbers, etc.
Habituation
The process by which a decrease in one's reaction (SUD level) to feared objects, activities, or situations is attained.
Extinction
The process where associations between feared objects, activities, or situations are unlearned. The fear declines with repeated trials.
Self-Efficacy
A person's belief in their ability to confront their fears and manage their feelings of anxiety/discomfort. Self-efficacy creates confidence and empowerment.
Emotional Processing
Learning to attach to new, more realistic beliefs about feared objects, activities, or situations. One can become more comfortable with the experience of fear.
Expectancy Violations
Expectancy violations disprove the client's expected reaction to fear. They allow a person to learn that the anticipated reaction doesn't happen, and may elicit a feeling of “That wasn't as bad as I thought it was going to be!”.
Automaticity
The ability to do any behavioral routine without conscious effort. Examples include walking, bicycling, driving, reacting to criticism with defensiveness, and escaping from emotionally uncomfortable situations.
Cognitive Restructuring
The process of learning a rational thinking response to triggers. Cognitive Restructuring can help develop an alternative way of thinking that isn't based on unhelpful or hurtful thoughts.
Exercise
Any type of physical activity. Aerobic exercise, in particular (such as running, swimming, cycling, stair climbing) produces endorphins, norepinephrine, and dopamine. These chemicals have been shown to help to reduce stress, anxiety, and depression. A common therapeutic goal is exercising daily for at least 20 minutes at 65% of hard effort. Twenty minutes is better than ten and ten is better than five.
Meditation
An activity that trains the brain to buffer stress and anxiety triggers. While relaxation may occur during a single meditation practice, practicing daily has a cumulative effect over time and trains the brain to tolerate unexpected triggers.
Behavioral Experiment Record
An experimental technique used to test, identify and correct distorted expectancies.
Recreation
The process of engaging in hobbies, sports, social activities is not superfluous. We need these activities in order to be our usual charming selves. Failure to get these needs met increases stress and reduces resilience.
Love
The human response to an affectionate friend, family member, pet, or intimate relationship. This response creates oxytocin which, in turn, helps down-regulate the amygdala, the part of the brain responsible for the fight or flight response.
Negative Reinforcement
Doing something to avoid something bad or reduce emotional discomfort. This serves as a function of protection from danger (getting out of the way of a car). It also represents the unhealthy avoidance that temporarily relieves anxiety, but maintains it in the long term, and makes functioning more difficult. Avoiding interactions for fear of being judged or saying something wrong is a form of negative reinforcement.
Section two

Anxiety Is Adaptive Until It’s Not

The most important function our brains perform in addition to keeping lungs breathing and hearts beating is to protect us. Anxiety and fear (fight or flight) are self-protective responses to a physical or psychological threat. In this mind-body experience, our whole physical being goes on a state of alert. We usually discriminate between fear and anxiety even though the emotional and physiological experiences have a lot in common. Fear occurs when there is an actual physical threat. Anxiety may relate more to anticipated threats than immediate.

In high anxiety, heart rate increases, respiration rate goes up, palms can feel sweaty, and the mouth can go dry. Some people feel like they must be having a heart attack. The discomfort associated with anxiety can range from minimal symptoms to mild, moderate, or severe. If you haven't lived with an anxiety disorder, you can still be sympathetic. As a human being you've experienced some level of anxiety from time to time. It may have been mild, like when you forgot to study for that midterm exam. Perhaps you felt butterflies in the pit of your stomach, you had difficulty falling asleep because of worry, your palms became sweaty, or your heart rate increased.

If you were driving on a dark stretch of road at night and suddenly, in your rearview mirror, you saw the flashing blue lights of a police cruiser, you would probably experience quite a surge of adrenaline! You may feel a sudden hot flush, pounding heart, dry mouth, and sweaty palms. Now imagine feeling those same sensations from out of nowhere and for no apparent reason, and you know how a panic attack feels. In panic disorder, that feeling comes unexpectedly, sometimes repeated at random intervals. The shock and discomfort of high anxiety will cause a person to avoid situations where they fear having a panic attack. In extreme cases, people with panic disorder don't dare venture outside their homes.

Minimal levels of anxiety may be dismissed quite easily for people without anxiety disorders (SUDs of one to three), but for those with anxiety disorders, even minimal symptoms can escalate into intense feelings (SUDs of seven to ten).

Working with people suffering from anxiety or distressing emotions provides some of the most gratifying experiences for clinicians. By teaching some useful tools, counselors get to see a real, long-lasting transformation with successful treatment. Moderate to severe anxiety can cause people extreme difficulty in completing everyday tasks. Concentration, decision-making, coping with everyday stress, and the ability to relax or fall asleep may be impaired. This can begin a downward spiral of physical and mental fatigue, leading to a loss of interest in daily activities and even depression.

Depression, like anxiety, could also be adaptive in helping a person withdraw from situations in order to recover from stress or take the time to solve or reflect on difficult problems. However, in today’s social environments marked by chronic stress and isolation, it can trap an individual in a cycle of withdrawal, overthinking, and impaired functioning, making it difficult to break out of the cycle and giving our conscious and nonconscious brain the experience we need to function well.

Fortunately, people with anxiety disorders and other disorders treated with CBT can significantly reduce anxiety and depression, a change in the brain that continues after therapy ends. Medications such as selective serotonin reuptake inhibitors (SSRIs) may also ameliorate some of the uncomfortable physical symptoms of anxiety and depression, enabling sufferers to function better as long as they continue taking medication. Most people prefer not to take medication, or to take as little medication as necessary. If they can learn to cope with or reduce negative emotions through their own effort, that is their preference.

Anxiety and depression can be evoked by many factors, none of which are elective. People don’t choose to have these reactions. Sometimes extreme events such as war, sexual and physical abuse, traumatic loss of a loved one or associate, natural disasters, or even drug use and medications may precipitate anxiety or other mental disorders. Names for some of these anxiety disorders include post-traumatic stress disorder (PTSD), panic disorder, major depressive disorder, and acute stress disorder. Sometimes, people may be genetically predisposed to anxiety or depression. However, people can develop mental disorders such as obsessive-compulsive disorder, depression, social phobia (social anxiety), specific phobia, separation anxiety, or generalized anxiety disorder without any obvious family history.

Intrusive thoughts, flashbacks (memories of traumatic events), guilty feelings, and even shame make people with these disorders hide their inner turmoil from others, and they often fail to get the help that they need. If their disorder significantly interferes with their ability to function, it may come to their physician’s attention, or they may seek a consultation with a counselor. Being given a diagnosis often brings great relief and the recognition that there is a pathway to improved mental health.

Some are relieved to learn they aren’t “crazy.” Most just want to know there is treatment and that they can get better.

Chapter 1 · Anxiety Is Adaptive Until It’s Not

They often ask, “What are my chances of getting better?” With OCD, which is one of the most difficult disorders to treat, studies indicate a 75% probability of significant improvement through CBT. Research also shows that only 20% of individuals who receive cognitive therapy suffer from acute and post-traumatic stress symptoms after six months, as compared to 67% who only receive supportive counseling. Other studies looking at PTSD and generalized anxiety disorder (GAD) indicate that when exposure therapy (purposely subjecting oneself to an anxiety-provoking situation) is included as a part of CBT for approximately sixteen to twenty sessions, a 50% reduction of symptoms may be achieved. The efficacy of CBT is also well documented for the treatment of panic disorder. Research reveals that by week six of treatment, approximately 76% of compliant individuals see a reduction in panic symptoms and by eleven weeks may be ready to reduce or end therapy. Medication and relaxation procedures used to treat panic disorder, when compared to cognitive behavioral therapy over a three-month period, have not been found to be as successful for panic disorder. However, recent studies have revealed that after only three months of cognitive therapy (the equivalent of eleven to twelve weeks), a significant reduction of panic symptoms is evident. With social and other specific phobias, even Internet-delivered CBT has shown an approximate 65% improvement rate, and that is with minimal therapist contact. Individuals with separation anxiety have also reported improvement with the use of both family-based and individual-based cognitive approaches.

These changes appear to make long-lasting differences in brain and behavioral functioning. For those who may be encouraged to do the challenging work of bearing the anxiety of exposure and response prevention and the work of cognitive restructuring, there is ample evidence of changes occurring in the brain as a result of CBT. Brain studies involving cerebral blood flow and the medial prefrontal cortex during anticipatory anxiety have shown reductions in blood flow while performing a variety of cognitive tasks (e.g., writing). Reduced blood flow indicates lower anxiety levels. The research shows that the practice of tasks such as anticipating a shock to the fingers actually decreases blood flow in the brain and lowers anxiety levels. In studies of social phobia, panic disorder, and post-traumatic stress, researchers have found that using emotional regulation techniques like those taught in CBT produces greater cognitive-control responses (i.e., right dorsolateral prefrontal cortex) in patients. For those suffering from PTSD, researchers have found a reciprocal relationship between blood flow in the medial prefrontal cortex and amygdala function in neutral and traumatic activity. Symptom severity was noted to decrease in the medial frontal cortex for both male veterans and female nurse veterans diagnosed with PTSD.

So, the good news is that people can manage, reduce, or eliminate the interference of anxiety and other mental health issues in their lives, just like others manage, reduce, or eliminate the interference of diabetes, coronary artery disease, or some other physical ailment. People can benefit from counseling, coaching, education, and behavior change in dealing with mental health, just as they have learned to manage their physical health.

Clinically, we ask our clients to describe the intensity of their anxiety in subjective units of discomfort (SUD), ranging on a scale from one to ten. A rating of one is almost no discomfort, and a ten represents the equivalent feeling of facing a bear alone in the woods. Minimal levels of anxiety may be dismissed quite easily for people without anxiety disorders (SUDs of one to three), but for those with anxiety disorders, even minimal symptoms can escalate into intense feelings (SUDs of seven to ten). This may lead to a perpetual state of worry and exhaustion at times.

Cultivating Awareness: Understanding Writing About Anxiety, Triggers, and Reactions

Why Write?

Writing has many benefits, and it is important to understand them to help motivate you to do the homework. Even when I wrote the word “homework” just now, I felt a little twinge of anxiety. Homework is often associated with something many people don't want to do–it could be difficult, and they would honestly rather be doing something fun. While some people enjoy writing, others are hesitant to write or “do homework” for one reason or another. Remember, this is not a school assignment about a subject that you are not interested in or won't really use in your practical life. These writing exercises are specifically about helping you develop skills and awareness you can use in daily life, to help YOU. It will not be graded or critiqued for grammar and spelling!

Benefits of Writing

  • Writing increases self-awareness, other-awareness, and situational-awareness.
  • Writing provides a break in automatic responses that may increase anxiety or unhelpful behavior.
  • Writing activates the rational, problem-solving portion of the brain.
  • Writing produces a valuable record to help you and your counselor detect themes in thoughts, feelings, and behaviors for evaluation and setting goals.
  • Writing helps identify intensity levels of anxiety on a scale of 1–10, which we call Subjective Units of Discomfort, or SUD, to help measure progress: “Hey, my SUD level is down from a 7 to a 5!”
  • Worst-case scenario writing helps produce anxiety for exposure toward the ultimate goal of habituation and feeling better.
  • People who have intrusive thoughts may be afraid to disclose those thoughts to others (fear of harming someone, liking inappropriate things, etc.). Writing them down serves as exposure by itself because of the fear of being discovered.

If your first thought is, “I don't like to write,” please see the benefits above and, well, how can I say this nicely? Write anyway. Here's a bit more encouragement.

Why We Ask You to Write by Hand

In this workbook, you will often be invited to write your responses by hand. This is not because handwriting is “magic,” and it is not because typing is wrong. Writing by hand simply adds one more layer of participation: your eyes, hand, body, attention, and words are working together. Research suggests that handwriting activates broader brain networks involved in movement, sensory feedback, attention, and memory than typing does (Van der Weel & Van der Meer, 2024; Marano et al., 2025).

For fear and trauma work, that slower pace can be useful. Handwriting may help you stay with the material long enough to notice what shows up, rather than rushing past it. It may also support deeper processing of words and meaning, since studies have found stronger learning-related brain responses after handwriting compared with keyboard typing (Kake et al., 2021).

At the same time, the most important part is not perfect handwriting. The important part is willingness, honesty, and repetition. Written exposure and expressive writing approaches have been shown to help many people reduce trauma-related symptoms, even when writing is delivered in different formats, including paper, electronic, or remote formats (Werner et al., 2021; Sloan & Marx, 2024). If handwriting is painful, inaccessible, or becomes a distraction, typing is a reasonable alternative. The goal is not to write beautifully. The goal is to face what fear has taught you to avoid, one sentence at a time.

A note on this digital edition

Because the chapter asks for handwriting, this page gives you both paths. Type into the exercise below if that is what you have available, or use Print / save as PDF to produce a clean paper version of the worry log and write it by hand. Either way, bring it to your next session.

One of the things we learn in counseling and psychotherapy is that we can't change what we don't monitor. Clients who benefit the most from CBT take notes, do homework, and get into the habit of writing their thoughts, feelings, triggers for anxiety, plans, and goals, on paper or on a computer. They learn to be open and honest about their experiences and collaborate in treatment. Overcoming anxiety requires hard work. To help you get into the swing of writing and becoming aware of your anxiety, triggers, and reactions, I suggest you begin with the same exercise I did when I worked with Dr. Gorbis (see Preface).

Exercise

15-Minute Worry Log — Thinking About Your Thinking

Five steps, exactly as written in the workbook. Nothing you type is saved, sent, or stored — closing this page clears it.

Download blank PDF Ruled lines, no interface — write it by hand, then bring it to session.
Step 1Why we are doing this — thinking about your thinking

This is the first exercise in the workbook, and it may be the most important one. Before you can change a thought pattern, you have to be able to see it. Counselors call this metacognition — the ability to observe your own thinking as if from the outside, rather than being swept along inside it.

Worry, like a physical compulsion, tends to run on autopilot. Most people have been worrying the same way for so long that the content and the triggers feel invisible — just "the way things are." This exercise is designed to interrupt that autopilot for fifteen minutes and help you begin to see what your mind actually does: what it worries about, how it worries, and what tends to set it off.

You are not doing this to fix anything today. The goal is simply to look. Whatever you write will be useful information — for you and for your counselor.

Step 2The writing task

Set a timer for fifteen minutes. Write freely about whatever is worrying you or making you anxious right now. Do not edit for spelling or grammar — just write. If you run out of things to say, keep the pen moving: write “I don't know what else to write” until something else surfaces.

If fifteen minutes feels like too much today, choose one of these:

15:00 Timer not started.

Remember: there is no wrong way to do this. The goal is to get it out of your head and onto the page so you can begin to see it.

Step 3Plan for obstacles — do this before you close the workbook

People follow through more consistently when they anticipate barriers in advance. Take one minute to answer:

What might get in the way of doing this exercise? (e.g., “I'll feel silly,” “I won't have time,” “I'll forget”)

If that happens, what is the smallest version of this exercise I am still willing to do?

Even writing one sentence still counts. It is the habit of observing your thinking that matters, not the length.

Step 4After you have written — read and notice

After your writing time is up, read back what you wrote. You are now doing something powerful: you are looking at your own thinking from the outside. This is metacognition in action.

As you read, notice and note the following:

What topics or worries came up most?

What thoughts, people, feelings, or situations seem to set off your anxiety?

Was there anything you wrote that surprised you, or that you didn't realize you were carrying?

This review build keeps everything in the browser only. There is no account, no database, and no transmission of what you write. Use Print / save as PDF if you want to keep a copy.

Step 5

What to bring to your next session

This log is not just a private exercise — it is the starting point for your work together with your counselor. Bring what you wrote (or your notes above) to your next session. Your counselor will use this to:

  • Help you identify your most significant worry themes and triggers.
  • Begin building your exposure hierarchy.
  • Practice noticing the difference between a thought and a fact — the core skill of cognitive restructuring.
Closing the chapter

Whatever you find in your writing, there is no wrong answer. The act of looking is the first step toward change.
