Cm. Chemtob et al., POSTDISASTER PSYCHOSOCIAL INTERVENTION - A FIELD-STUDY OF THE IMPACT OF DEBRIEFING ON PSYCHOLOGICAL DISTRESS, The American journal of psychiatry, 154(3), 1997, pp. 415-417
Objective: Following a catastrophic natural disaster, the authors eval
uated whether brief psychological intervention (debriefing 6 months la
ter) reduced disaster-related psychological distress as measured by th
e Impact of Event Scale. Method: Two groups of subjects who had been e
xposed to Hurricane Iniki in Hawaii were assessed before and after par
ticipating in a multihour debriefing group. The intervention aimed to
provide ventilation of feelings, normalization of responses, and educa
tion about normal psychological reactions to the disaster in a context
of group support. To provide a partial control for the passage of tim
e, the pretreatment assessment of the second group was concurrent with
the posttreatment assessment of the first group. Results: A repeated
measures analysis of variance indicated that Impact of Event Scale sco
res were reduced in both groups after the treatment. Conclusions: Ther
e is preliminary empirical support for the effectiveness of postdisast
er psychological intervention and for the feasibility of treatment res
earch in postdisaster environments.
