The Critical Incident Stress Management (CISM) model for crisis intervention was developed for use with emergency service personnel. Research regarding the use of the CISM model has been conducted among civilians and high-risk occupation groups with mixed results. The purpose of this study is to examine the social validity of the CISM model for school-based crisis intervention as perceived by school psychologists and school social workers trained in the model. The results suggest that the CISM Model had a positive effect on service delivery, but the training itself did not adequately address the developmental appropriateness or the cross-cultural appropriateness for school-based application.
