In this phase psychological service personnel are participant observers. That is, as well as being concerned to survive and preserve themselves, they should help others do the same. In the process they may use their professional skills for psychological first aid, such as help to reunite missing family members. Helpful interventions which enhance (not reflect on) adaptive strategies of survival, may lead to trust and acceptance in future interventions. Premature interventions, such as, “It is normal to feel anxious about your missing child.” may be felt as quite unhelpful. Psychological service providers can provide a “mind” where impulse to action is predominant. They can help clarify and resolve some impulsive and inappropriate actions and conflicts, such as excess guilt making people expose themselves to unnecessary danger.
