Perfectionism and the effects of demanding standards

A person can be careful, ambitious and reliable while spending far too much time preparing, replaying conversations or deciding whether work is finished. Those qualities may have helped them succeed, making it difficult to recognise when the way they manage standards is also causing strain.

I see this in people whose work genuinely requires competence and precision, even when they do not identify with the word perfectionism. They may describe mistakes as unusually costly, rest as something to be earned and good results as a brief relief before the next task.

Striving and concern about mistakes

A 2025 umbrella review combined 43 meta-analyses involving almost 700,000 participants and distinguished perfectionistic striving from perfectionistic concern. Striving describes the push towards very high standards, while concern includes repeated doubt, worry about mistakes and a sense that others expect flawless performance.

Both dimensions were associated with poorer mental health, with the link clearer and more consistent for perfectionistic concern. An association cannot determine why an individual is struggling, but it gives assessment a reason to examine the meaning attached to a result alongside the standard itself.

A mistake may feel like evidence of inadequacy or a risk of being exposed, even when the person understands that errors occur in competent work. That response can account for why a proportionate correction fails to settle the concern.

Preparation as a response to threat

Thorough preparation may become a way to prevent criticism or misunderstanding, particularly when someone expects that covering every possibility will protect their standing. The rule can influence working life without ever being expressed explicitly.

Extra checking can reduce anxiety and produce excellent work, giving the person a reason to repeat it. Costs may appear through slower decisions, difficulty delegating or procrastination on a task whose result feels especially consequential.

Success can also be dismissed as expected or lucky, leaving the standard to increase again. Looking at how the person responds after a completed task may reveal more about the maintaining pattern than debating whether a high standard is objectively unreasonable.

A person may be able to describe their rules quite clearly once we look at a particular task, including the expectation that exhaustive preparation will prevent criticism. The rules become harder to examine when they have also produced recognition and good results, because reducing the extra effort can feel like abandoning what has made them dependable.

What therapy can work on

Treatment can preserve care and ambition while examining rigid rules that make tasks excessively time-consuming or difficult to begin. A behavioural experiment might compare a fit-for-purpose standard with the prediction about what will happen if the person stops checking earlier.

The exercise needs to fit the actual consequences of the task, with room to examine self-critical thoughts and any older learning that made mistakes feel unsafe. Rest and delegation may also need practice before they feel comfortable, particularly when constant usefulness has become tied to identity.

A meta-analysis of randomised trials of CBT for perfectionism found changes in several perfectionism measures and smaller improvements in anxiety and depression. A later re-analysis raised concerns about reliable change, durability and dropout, limiting confidence about how many people benefit and for how long.

Those findings support using methods with a clear rationale and ongoing review, while leaving room to address interpersonal expectations, chronic overcontrol and workplace conditions. A standard program may miss important parts of the formulation, including how fear of doing therapy incorrectly affects the sessions themselves.

In my work, I would want to distinguish the care a task needs from the additional effort used to settle a judgement about the self. An ordinary email may be checked repeatedly long after its meaning is clear, while a more consequential task may be postponed because no opening sentence feels good enough.

Adjusting effort to the situation

A flexible standard can remain demanding where precision is required, while allowing less time for an ordinary internal email than for a legal submission. The plan needs to reflect importance, capacity and available time, so that effort can change without every adjustment becoming a judgement about character.

In daily review, I would look at what follows a mistake, compliment or completed task, including whether the person can take in a satisfactory result and move on. If another audit begins immediately, that sequence gives us a specific response to examine and practise changing.

Rest or delegation can feel undeserved when the person has learned to secure approval through being useful. Practising either may therefore involve tolerating guilt and reviewing what happened afterwards, with attention to the interpersonal expectations that make the change feel difficult.
