This study was designed to find out the causes, effects and management of anxiety among cadets of Nigerian Defence Academy, Kaduna. Sources of anxiety are issues that are intricately related to Academy life because of its peculiar nature, and these may have serious consequences on the lives of cadets. The three faculties in the Academy were used for this study. From these faculties 278 and 205 cadets and academic staff have been used respectively as subjects. Two sets of validated questionnaires were used to gather the data analysed for the study. Four hypotheses were formulated on the causes, effects and coping strategies. The focus of hypothesis was to identifv the difference in handling anxiety issues among the levels of cadets in the academy. The main statistical tool applied for testing the hypotheses was the T-test. It was found out that the cadets differ significantly on what causes anxiety for them, the effects and the coping strategies they apply when under anxiety. For hypothesis 1 the T-test analysis gave value of 0.42, which is higher than the critical value at P<0.05. Testing hypothesis 2 the computed t value of 0.76 shows that the cadets differ in their response as to the effect of anxiety in them. The frequency distribution table shows that the effect of anxiety on year 2 cadets differs from year 3 cadets. Therefore this hypothesis is rejected. On the coping strategies both cadets and staff differ significantly in their choice of coping strategies. That shows that cadets identified the causes of anxiety in the academy, the effects it has on them and different coping strategies they use. It is recommended that the Academy should have functional counseling units in each faculty. Such counseling units should develop appropriate seminar/workshop materials on anxiety issues and its management. Such counseling units should also hold regular workshops for and with Academy Officers who usually have the first contact with the new cadets on arrival to the academy
