[4] NET is conducted around the use of the lifeline, which serves as a reference point for both the therapist and the patient during the therapy.
Symbols' size, shape, and color may also be used to indicate events with greater or lesser intensity or significance.
The largest stones are then chosen to be dealt with since they represent the greatest traumas the patient needs to reprocess or overcome.
Building a lifeline can also help strengthen the therapeutic relationship and create an estimation of the number of sessions a patient may need.
Studies have shown NET to reduce symptoms of post-traumatic stress disorder and depression, but few comparisons have been made to other available treatments.
