A Pattern Interrupt in NLP is a series of interruptions that break a habit or state. So much so, that the interruption becomes part of the pattern. If you think of strategies, where to make a behaviour work it needs 1,2,3,4 to be firing in the right order, or A,B,C before it works, think of interrupting A,B,C. When you keep interrupting the behaviour or state as it’s trying to work itself, the pattern can’t fire off and eventually the person experiences the intervention you are using as part of the process and therefore can’t successfully do the old pattern anymore!
This is not the same as a break state.
