Examined psychiatric morbidity in 204 new and indigenous residents (aged 22-35 yrs) from a suburban part of Khartoum, Sudan. Measures used included the Self-Rating Questionnaire (T. W. Harding et al; see record 1981-21896-001), the Eysenck Personality Inventory, and a Sudanese rating scale of anxiety and depression. Psychiatric and medical assessments were also carried out. Results show that 40.3% of the Ss had at least 1 psychiatric symptom, and 16.6% received clinical diagnoses according to Diagnostic and Statistical Manual of Mental Disorders (DSM-III). The most common diagnoses were depressive illness and generalized anxiety. A higher rate of mental symptoms was found in Ss most exposed to the stress of modern life, particularly blue-collar workers with stable but unsatisfactorily paid jobs.
