The aim of this study was to evaluate the effect of a cognitive– behavioral, biofeedback-assisted intervention to impart skills for coping with stressful encounters in a nonclinical adolescent population. Israeli Arab and Israeli Jewish participants completed pre- and postintervention questionnaires assessing state anxiety, test anxiety, behavior symptoms, hostility, and selfesteem. Electrodermal activity was recorded using biofeedback. From pre- to postintervention, scores of state anxiety, test anxiety, behavior symptoms, and self-esteem, but not hostility, changed significantly in the intervention group as compared with the control group. A significant Group School effect was evident for state and test anxiety and behavior problems, indicative of higher reductions in the Arab group. The cognitive– behavioral program proved an effective preventive intervention for adolescents.
