Coercive control, and every tactic it runs on.

What is considered coercive control?

The distinguishing feature is that it is a pattern, not an incident. Any single item below could be explained away on its own, and that deniability is part of how it works.

It also does not require violence. Most of what makes these relationships so difficult to describe, and so hard to get taken seriously, happens without anyone being hit.

The usual test is effect rather than intent. If the overall result is that your freedom of action has narrowed, that is the thing being described, whatever each individual behaviour looked like.

• Isolation. Contact with friends and family becomes difficult, expensive or not worth the argument.
• Monitoring. Your location, phone, spending or messages are checked, often framed as care.
• Financial restriction. Access to money, work or your own accounts is limited or supervised.
• Rule-setting. What you wear, eat, watch or say is subject to approval that shifts over time.
• Degradation. Criticism aimed at your competence and worth rather than at anything you did.
• Threats and intimidation. Not always of violence. Threats about children, money, immigration status or reputation.
• Reality control. Your account of events is routinely overridden, which is where gaslighting sits.

What are the subtle signs of coercive control?

The obvious version is easier to name than to live with. The subtle version is the reverse, and it is where most people spend years.

These signs are about you rather than about them, because the behaviour itself is built to look reasonable from outside.

• You run decisions through their likely reaction before your own preference.
• You have stopped mentioning certain people, plans or purchases in advance.
• You feel relief when they go out, and a tightening when you hear the door.
• You have a curated version of your relationship that you give other people.
• You cannot remember the last time you disagreed out loud.
• Your world has quietly narrowed, and you cannot point to the decision that narrowed it.

What does coercive control do to you?

There is now good evidence on this. A systematic review and meta-analysis published in Trauma, Violence and Abuse in 2024 searched for every study measuring coercive control against mental health outcomes.

It identified 68 studies and pooled data from 45. Coercive control was moderately associated with post-traumatic stress disorder and with depression.

Two things in that review are worth knowing because almost nobody repeats them. The associations were comparable to those for psychological abuse generally, so this data does not show coercive control to be uniquely damaging. And only one study examined complex PTSD, so the popular claim that coercive control causes complex PTSD is not yet backed by pooled evidence.

The authors also describe coercive control as an under-researched form of intimate partner violence, and conclude that people exposed to it need mental health care. Moderate is not small, and it is measured across tens of thousands of people rather than asserted.

Is coercive control illegal?

In some places, and this is changing quickly enough that local advice matters more than anything written here.

It is a criminal offence in England and Wales under section 76 of the Serious Crime Act 2015, and in Scotland under the Domestic Abuse (Scotland) Act 2018. Ireland criminalised it in the Domestic Violence Act 2018, and several Australian states have introduced offences more recently.

In the United States there is no federal offence, but a number of states, California and Connecticut among them, recognise coercive control within family law, which can matter for protective orders and custody.

Two practical notes. Where it is an offence, a pattern is what gets charged, so records of small incidents over time are more useful than one dramatic account. And nothing here is legal advice, which has to come from someone who knows your jurisdiction.
