This study investigated psychological reactions of adolescents to a severe stress situation--the evacuation of the Sinai settlements. The research focused on emotional reactions of anxiety and anger to this stress situation. Two central problems were investigated: The intensity of the emotional responses of anxiety and anger of the adolescents to the stress situation, before and after the evacuation, and the impact of three intervening variables on these emotional reactions--cognitive perception of the political situation, family functioning, and personality characteristics. Data for this study were collected in a regional high school in Israel from 418 pupils in 9th through 12th grades. Seventy-eight of the pupils lived in the Yamit area. Measurements were obtained at three points in time: 6 weeks and 1 week before the evacuation and 2 months after it. The results supported the predicted trend that adolescents in the Yamit group before the evacuation would score higher on state anxiety and state anger than would those in the comparison group. Two months after the evacuation there was a significant drop in those scores. The trait measures remained stable in both groups and no significant differences were found between the two groups on these scores. Concerning the impact of the three intervening variables on the intensity of the state emotional responses, the results did not support any of the hypotheses.
