ABSTRACT
As the researches regarding this topic in Egypt are actually few, hence, it was thought of utmost necessary to undertake a work to study conversation disorder in adolescence in Egypt. Structured psychiatric sheet was applied to all the students registered in Qalyoub Preparatory School during the year 1988 - 1989 [730 students]. 34 students were found with histories of conversion disorder. These cases were thoroughly studied by comparing with 34 controls selected from the same school and matched for age, sex and social class. The female: male ratio was 1: 0.7, the mean age was 14.29 +0.99. 73.5% were from low social classes, 71.6% came from large families but the disorder was insignificant. The cases showed scholastic retardation while conversion disorder could occur in students with low, average or high intelligence. All the cases complained of family communication problems with significant difference. 41.7% had an aggressive father and 47.1% had an aggressive mother, while 26.4% had an overprotective father and 38.23% had an overprotective mother but with no significant difference with the controls. The predominant conversion symptom was seizure, all the cases had psychological stresses before the onset of conversion disorder. The cases scored high neuroticism, psychoticism and low extroversion
