Addresses the impact of war-related stressful life events on the physical and psychological health of 540 families living in war conditions in Lebanon for the past 12 yrs. Health outcome is represented by indicators of somatization, depression, psychological symptoms, and interpersonal and marital relations. Associations are described between elements of war stress and the health outcome variables for mothers, fathers, and adolescents; the role of mediating factors of social support and class are discussed. Economic impact, daily hassles caused by the breakdown of community services, and restricted contact with friends and relatives caused more stress than the constant threat of violence. High levels of somatization and psychological symptoms, increased conflict in interpersonal relationships, and positive levels of marital relationship were also found.
