I did this short post on our counseling center webpage. We are doing disaster response crisis counseling related to Typhoon recovery in the Philippines. We generally use the NOVA method (National Organization of Victim Assistance). We are pretty comfortable with it. Some prefer to use CISD, but we believe that CISD is more appropriate for hidden victims (aka recovery volunteers). However, there is a disagreement between PFA (Psychological First Aid) and NOVA. PFA is good, but NOVA is pretty easily teachable. Right now we have decided to stay with NOVA (mostly) but make some adjustments to reduce the risk of retraumatization.
