You already know the standard is expensive. What you do not have is the receipt. This sheet produces one, in two weeks, for a single standard, and then asks you to change one number and watch what happens.
The short answer: clinical perfectionism runs on a loop that treatment interrupts at two points, the rule ("if it is not perfect, then…") and the behaviour that serves it (checking, redoing, over-preparing, avoiding). The randomized trials of CBT for perfectionism work on those two levers, and their effects on concern over mistakes were large. This worksheet is the self-help version of the first two sessions. It does not replace therapy; it tells you whether you need it.¹ ²
Pick one standard and write it as a rule
Choose the single domain where the standard bites hardest this month: work, school, appearance, parenting, fitness, tidiness, writing, code.
- Domain:
- The standard, as you actually apply it (not the polite version): "I must "
- The rule underneath: "If I do not, then " (write the feared consequence in full: they will realize I am a fraud, I will lose the job, I will not be able to stand myself)
- Who set this standard? ☐ Me ☐ Someone specific: ☐ "Everyone"
The last line matters. Rising perfectionism across recent decades has been driven most by the belief that other people demand perfection, not by higher personal ambition.³ If the answer is "everyone," the standard is partly weather.
Keep the ledger for one week
Each day, log every act the standard produced. Be literal.
| Day | Redoing or re-checking (minutes) | Over-preparing beyond what the task needed (minutes) | Delayed or avoided because it might not be perfect (what, how long) | Sleep lost, meals skipped, plans cancelled | Self-criticism (rate 0–10, worst moment) |
|---|---|---|---|---|---|
| Mon | |||||
| Tue | |||||
| Wed | |||||
| Thu | |||||
| Fri | |||||
| Sat | |||||
| Sun |
Week-one totals: minutes redoing · minutes over-preparing · things avoided · nights or meals · average self-criticism / 10.
Score the four questions
For the domain in Step 1, mark one box per row.
| Left | Right | |
|---|---|---|
| When I meet the standard… | ☐ my view of myself rises and holds | ☐ it rises briefly, then the standard moves |
| When I miss it… | ☐ I am disappointed and adjust | ☐ I attack myself as a person |
| The pursuit costs me… | ☐ little I value | ☐ sleep, health, relationships, time, or the work itself |
| When I can see the damage… | ☐ I renegotiate | ☐ I cannot lower the bar |
Right-column marks: / 4. Four is the working definition of clinical perfectionism: worth over-dependent on demanding self-imposed standards, pursued despite adverse consequences.¹ Two or fewer is the ordinary cost of caring.
Design the good-enough experiment
Change one number for week two. Not the whole standard: one number.
- The change (pick one): ☐ submit at percent of my usual polish ☐ one proofread instead of ☐ minutes of preparation, then stop ☐ send or publish by o'clock regardless ☐ leave visibly imperfect
- My prediction of what will happen (be specific; include how bad, 0–10):
- How I will know (the observable result, not my feeling about it):
Write the prediction before you run the experiment. The prediction is the perfectionism talking; the record in Step 5 is the treatment. Behavioural experiments of this shape are the core of the CBT protocols that produced medium-to-large effects on perfectionism, depression and anxiety in randomized trials.²
Run week two and record what actually happened
| Day | Did I hold the new number? | What actually happened (observable) | Predicted badness 0–10 | Actual badness 0–10 | Self-criticism 0–10 |
|---|---|---|---|---|---|
| Mon | ☐ | ||||
| Tue | ☐ | ||||
| Wed | ☐ | ||||
| Thu | ☐ | ||||
| Fri | ☐ | ||||
| Sat | ☐ | ||||
| Sun | ☐ |
Compare: predicted average vs actual average . Minutes reclaimed this week: . Self-criticism this week vs last: vs .
If the actual badness ran far below the prediction, you have the evidence the rule was wrong, in your own handwriting. If the actual badness matched the prediction, write down exactly what happened; a real consequence is information too, and it usually points at a different rule.
Decide what happens next
Tick what is true after two weeks.
- ☐ I could not hold the new number even once, or holding it produced panic rather than discomfort.
- ☐ Self-criticism stayed at 7 or above on most days.
- ☐ The ledger shows costs I had been hiding from myself (lost sleep, cancelled plans, avoided work).
- ☐ Any thought along the lines of I would rather not exist than fail at this.
- ☐ The domain is food, weight, or exercise.
- ☐ Rituals or intrusive thoughts I would rather not have are part of the picture.
Zero ticks: repeat with a second standard; the method is yours now. One or two ticks: this is where a therapist who treats perfectionism directly earns their fee; bring both weeks of the ledger to the first session. The fourth box, ticked: call or text 988 today. The fifth or sixth box: the problem may have a more specific name and treatment. Eating disorders → · OCD, and the matching trap →
What happens next
A therapist trained in CBT for perfectionism will recognize this sheet: the rule, the ledger, the experiment and the comparison are the first sessions of the protocol. Bringing it means you skip the part where you explain that you look fine. What to ask a therapist about perfectionism, and the evidence behind the treatment →
