Basic Protocol:

Group crisis interventions often take place at or near the site of the community trauma coincident within the first few days or week of the trauma event. This is the most commonly called upon service.
The technique allows response team members to address thoroughly all of the elements of the crisis intervention; to educate participants on the common pattern of crisis reactions and what long-term stress reactions are to be expected; and to help participants consider coping responses. The group sessions usually last between one and a half hours to 3 hours.

Group Defusing:

A group defusing is usually conducted at or near the site of the community trauma coincident within the first few days or week of the event. Often the primary target populations for a defusing are emergency workers who face competing demands on their time, but short defusing sessions can be helpful to others as well.

Extended Trauma Protocol:

Occurs when the crisis team members arrive in the middle of an extended trauma event.

Repetitive Group Intervention Protocol:

The process of repetitive group intervention protocol is employed with a community perceives itself as being under siege as a result of numerous different disasters having taken place in a relatively short time period or where the ongoing trauma event (crime) has caused community members to live in fear or feel helpless.

Retrospective Group Crisis Intervention Protocol:

This intervention may occur months after the trauma but can also take place years later.
