Poster (in Polish) presented at the Congress of Polish Psychatrists (KPP 2001)

I participated in student scientific meetings previously, but participation in the Congress of Polish Psychiatrists was my first exposure to a major scientific conference. Together with the regular staff of the Child Psychiatry Clinic in Warsaw, we presented results of a 2-year investigation of prevalence of tic disorders among Warsaw schoolchildren. These results on competence and behavioural problems among children with tic disorders were not published elsewhere!
