A CBT thought diary records one emotional event: what happened, what you felt and how strongly, what crossed your mind in its original wording, and how you responded. From there you can weigh the evidence for and against that thought, write a balanced view that still sounds true, and choose one next step.
The entry can be brief. If the emotion feels too intense for a full entry, note the situation, emotion, and automatic thought, then return to the rest later.
A CBT thought diary starts with one event
A regular diary can hold memories, plans, or a story about the day. A CBT thought diary separates a specific experience into the situation, your interpretation, your emotions, and your response.
The NHS describes a thought record as a structured CBT exercise with seven prompts. Layouts vary, but many include the situation, emotion, automatic thought, evidence, a balanced perspective, and a second emotion rating.
Use it when you want to understand a sharp reaction, repeated trigger, or puzzling urge. You might make several entries in a week, then leave it untouched for days.
“CBT thought diary,” “thought diary CBT worksheet,” “CBT thought journal,” and “cognitive diary” often name the same family of exercises.
Capture four details while the event is still clear
A 2022 study of a conversational tool for thought recording identifies four core fields: situation, emotion, automatic thought, and behavior. Its review of clinical practice notes that therapists ask clients to complete records close to the difficult situation. During an argument or meeting, a short note can preserve the thought and context for a later review.
1. Describe the situation as a camera would
Record the smallest factual snapshot that identifies the trigger:
- Where and when did it happen?
- Who was present?
- What did someone say or do?
“My manager was angry with me” interprets the event. “My manager read my draft, paused, and said, ‘Let’s revisit the opening’” records what a camera or microphone could capture.
The trigger may also be internal: a memory, mental image, physical sensation, or prediction.
2. Name the emotion and estimate its intensity
Choose an emotion word such as anxious, hurt, angry, ashamed, guilty, or sad. More than one may fit. Rate each from 0 to 100 as a rough marker.
Body sensations can help identify the state: a tight chest, warm face, clenched jaw, or heavy stomach. “I felt stupid” is a judgment, so it belongs under thoughts. “I felt ashamed, 70/100” names an emotion.
3. Write the automatic thought in its original wording
The American Psychological Association defines automatic thoughts as instantaneous and habitual. They may arrive as a sentence, image, memory, or prediction, then disappear once you start explaining the event.
Record the thought as it appeared:
- “They think I’m incompetent.”
- “I’m going to lose this friendship.”
- An image of everyone noticing your mistake.
Keep the original wording. If several thoughts appeared, mark the “hot thought,” the one with the strongest connection to the most intense emotion. You can rate your belief in it from 0 to 100.
4. Record the response or urge
Note what you did and what you wanted to do: reread a message ten times, go quiet, apologize, leave the room, or cancel a plan.
This field links the thought to your action. The same anxious prediction can lead to different behavior across entries, which may help you spot a pattern later.
Examine the thought after the first capture
Start with the hot thought and compare it with the available facts.
List evidence for and against the thought
Evidence for the thought includes observable facts that support it. Evidence against it includes facts that your first interpretation left out.
Write both, even if one side feels thin.
For “They think I’m incompetent,” supporting evidence might be: “My manager asked me to rewrite the opening.” Evidence against it might be: “They approved the analysis, gave one specific revision, and did not comment on my competence.”
An upsetting thought may point to a real problem. If the evidence supports your concern, you might solve the problem, ask a question, or set a boundary.
Write a balanced thought that fits the evidence
A balanced thought uses facts from both sides. It may feel less comforting than a positive affirmation:
My manager wants a different opening. I do not know what they think of my overall ability. I can ask what needs to change and revise this section.
This version keeps the uncertainty and identifies an action you control.
Re-rate the emotion and belief
Rate the main emotion again, then rate your belief in the original hot thought. A lower number can show that your view shifted; an unchanged or higher number also tells you something.
One entry may not change how you feel. In a randomized laboratory study of 100 participants, the thought-record and control groups did not differ on affect measures after a stress task. The researchers tested one brief use in a lab, so the result does not answer every question about daily use. The exercise gives you a way to inspect an experience, without promising relief on demand.
Finish with one possible next step, such as asking for context, delaying a reply, returning to a task, discussing the entry with a therapist, or taking no action.
A completed CBT diary example
Suppose a friend cancels dinner by text:
| Field | Example entry |
|---|---|
| Situation | At 6:06 p.m., Alex wrote, “I can’t make it tonight. Sorry.” |
| Emotion and body | Hurt 80/100; anxious 60/100; stomach dropped |
| Automatic thought | “They are tired of me.” Belief: 75/100 |
| Urge or action | Wanted to stop replying and cancel next week’s plan |
| Evidence for | This is the second cancellation this month |
| Evidence against | Alex rescheduled after the first cancellation; we had a warm conversation this morning; the message gives no reason |
| Balanced thought | “I feel hurt by a second cancellation. I do not know the reason or what Alex thinks of me. I can ask whether something happened and whether they want to reschedule.” |
| Re-rating | Hurt 55/100; anxious 35/100; belief in original thought 40/100 |
| Next step | Reply after dinner and ask what happened |
The balanced thought keeps the disappointment while removing a conclusion the facts do not support. It leaves room for a direct conversation.
Use a short version when attention is limited
Some moments leave little room for seven columns. Use three lines:
- Situation: What happened, in observable terms?
- Emotion: What do I feel, and how strong is it?
- Automatic thought: What went through my mind?
Add the urge or action if you can. Return to the evidence and balanced perspective after the meeting or once you reach home, while the event is still clear.
If the thought is hard to name, start with the body sensation or urge. Ask, “What did this moment seem to say about me, the other person, or what might happen next?” If you cannot name the emotion, record the sensation and choose the closest word for now.
A guided check-in can hold the structure for you
Paper, a notes app, and a worksheet can all hold a CBT thought diary. Remembering the questions while you feel upset may be harder than recording the answers.
Leaflo offers a guided, CBT-inspired check-in based on the emotions you select. It asks about the situation, thoughts, fears, boundaries, needs, and a possible next step. You can review entries for patterns and export selected entries for yourself or a therapist.
Leaflo is a reflection tool rather than psychotherapy or medical care. It guides the entry while you interpret it; it cannot determine whether a thought is true or promise to change your mood.

A thought diary is one format inside a wider practice: CBT journal vs regular diary shows when structure helps and when it gets in the way, a CBT diary example walks through completed entries, and CBT journal prompts gives you the questions to use when the fields feel abstract. If you want the specific question to ask at each of the seven stages, including the evidence questions that make the balanced thought believable, see thought record questions.
