Developed by Paul Hewitt and Gordon Flett, this model breaks perfectionism into distinct dimensions rather than treating it as one trait. First is the trait direction: self-oriented (I require myself to be perfect), other-oriented (I require you to be perfect), and socially prescribed (I believe others require me to be perfect). Layered on top is the interpersonal expression, splitting the need to BE perfect from the need to APPEAR perfect through self-promotion, never showing imperfection, and never disclosing imperfection. A fourth facet is the self-relational component, the harsh critical inner dialogue. Crucially the model separates perfectionism, driven by a core sense of being flawed, from excellencism, the healthy striving for hard standards. Because the driver is self-repair, achievement never satisfies it, which is why identifying the dimension matters more than working harder.
Origin
Built by clinical psychologists Paul Hewitt and Gordon Flett over decades of research and clinical work with Olympians, artists, and high performers, distinguishing perfectionism as a self-repair strategy from healthy achievement striving.
Core principles
- 01Perfectionism is a way of being in the world, not a set of high standards
- 02At its core sits the belief 'I am not enough' that the striving tries to repair
- 03The trait has a direction: toward the self, toward others, or perceived from others
- 04It also has an expression: needing to BE perfect versus needing to APPEAR perfect
- 05Achievement never resolves it, so mapping the dimension matters more than raising output
How to run it
- 1
Locate the core belief
Recognise that under the striving is a sense of being flawed, defective, or not enough to have worth or belong. The behaviour is an attempt to rectify that, not simply to excel.
Pro tip Ask what the striving promises: to be loved, to belong, to matter. That promise reveals the wound.
Watch out Do not confuse high standards with perfectionism; standards alone are healthy.
- 2
Identify the direction
Determine which of three trait dimensions dominates: self-oriented (I must be perfect), other-oriented (you must be perfect), or socially prescribed (others demand my perfection).
Pro tip Socially prescribed and self-oriented are the dimensions research links to the worst outcomes.
- 3
Separate being from appearing
Distinguish the need to actually be perfect from the need to appear perfect to others, which shows up as self-promotion, never displaying flaws, and never disclosing them.
Pro tip Think of a politician: they need to appear perfect far more than they need to be perfect.
- 4
Listen to the inner dialogue
Examine the self-relational component, the running conversation with yourself. Perfectionists speak to themselves in ways they would never speak to a spouse or child.
Pro tip Ask: if I said this dialogue to a loved one, what would happen? The absurdity exposes the cruelty.
- 5
Distinguish repair from excellence
Ask whether the striving is trying to correct a defective self or to push toward a hard goal. Pushing the self is excellencism and adaptive; repairing the self is perfectionism and maladaptive.
Pro tip Excellencism can produce the same output without the physical and relational costs.
Watch out Perfectionism is associated with worse productivity, relationship breakdown, and even early death.
- 6
Work the underlying need, not the trait
Recognise that the exit is not reducing a perfectionism score but addressing the deeper needs for worth, belonging, and acceptance. Change comes through experience and connection, not worksheets.
Pro tip Treat perfectionism like knee pain: fix the cause and the symptom fades on its own.
Watch out Purely information-based or CBT worksheet approaches often fail to shift the most pernicious dimensions.
In the wild
A suicidal university student in a make-or-break course told Hewitt he had to earn the highest grade. When he returned having scored an A+ and the top mark in the class, he was more depressed than ever. His reasoning: the fact that he had to work so hard to get it proved he was not truly capable. A clear success was converted into confirmation of unworthiness, showing how self-oriented perfectionism makes achievement irrelevant to the underlying belief.
→ Illustrates that success does not touch the core belief while failure confirms it.
Chris Williamson described running nightclubs where his criteria for success kept moving away from him. First the event had to be full; then he had to suffer to earn it; eventually a full event without suffering counted as a failure because he had not paid enough. Every configuration produced a reason to feel inadequate, demonstrating how the driver is self-repair rather than any external result.
→ Shows the goalposts moving so no outcome can ever satisfy the need.
Common mistakes
Treating perfectionism as just high standards
Conflating healthy excellence-striving with perfectionism hides the self-repair driver. The two are different psychological constructs with opposite outcomes.
Chasing achievement to fix the feeling
Believing the next accolade will resolve not-enoughness only ups the ante. Success feels empty and failure confirms the wound.
Trying to fix it with worksheets alone
Information and homework do not teach new ways of being any more than a lecture teaches you to ride a bike. Change happens through experience and connection.
Is it for you?
Best for
High performers, clinicians, and anyone who suspects their striving is driven by not-enoughness rather than healthy ambition.
Not ideal for
People with genuinely high standards and secure self-worth, whose striving is excellencism rather than perfectionism.
From the transcript
“at the core I'm not enough. That there's something that is flawed, defective. I'm not I'm just not enough either to have worth or to…”
“one is a driver of the behavior, the self, other social. And then these other pieces is... I need to appear perfect to you”
“there's a domain of research that distinguishes perfectionism from what's called excellencism”
