Which phase does not belong in the recovery process of PTSD?

The "calm, tranquil 'before the storm' phase" is not a recognized part of the recovery process for PTSD. The recovery process typically involves active engagement and confrontation with the trauma, rather than a period of tranquility. The readiness phase is about preparing individuals to face and process their trauma. The confrontation phase involves directly addressing the traumatic memories and feelings associated with the PTSD. The integration phase is where the individual begins to incorporate their experiences back into their life in a healthy way, facilitating healing and growth. Therefore, the first phase described does not reflect the active nature of recovery from PTSD, making it the correct choice for this question.
