This article will describe ways in which communities react to severe c
rises, both on a local and on a national level. Based on experiences i
n Israel over the past 20 years, including recent traumatic events suc
h as the assassination of prime minister Yitzhak Rabin and the terrori
st suicide bombings, and on an intervention in Buenos Aires, Argentina
, after the bombing of the Jewish Community Centre in July 1994, a mod
el is presented to describe different stages of reaction. The importan
ce of the creation and development of community prevention and interve
ntion programs is stressed. Emphasis is placed on the role of the scho
ols and the school psychologists in developing and implementing such p
rograms, and on their critical role in dealing immediately with crisis
situations and their aftermaths. The prevention program emphasizes th
e fostering of inner strengths and resources in children and teachers
('inoculation'), and makes provision for dealing with emotional suppor
t for the professionals in charge of helping the community in times of
crisis. Finally, a model for the future development of the profession
of school psychology into a broader community service is proposed.
