De driedimensionele structuur van positieve en negatieve symptomen; een literatuurbespreking
J.A. Dalebout, J.G. Goekoop
The literature on preconceived syndromes of positive and negative symptoms in schizophrenia is briefly presented. Factor analytic studies demonstrate the segregation of symptoms of chronic schizophrenia into three syndromes: psychomotor poverty, disorganisation and reality distortion. According to the available research the three-dimensional description of chronic schizophrenia should be preferred.
