Internship Nursing Students (Control group) without (DBT) intervention sessions. Tool one A
structured Interviewing Questionnaire, Tool two: Zung Self-Rating Anxiety Scale, Tool three: Zung
Self-Rating Depression Scale, and Tool four: The Impact of Event Scale (IES) were used in this
study. This study was carried out at the Faculty of Nursing, Menoufia University. A quasi -
experimental research design two groups (Study and control group) was utilized. Results: There

subscales between the study and control group before the (DBT) intervention sessions while after

scores were significantly lower than the control group. Conclusion: During the epidemic prevention

psychological demands of medical and nursing students as well as college psychological
