Clopenthixol and flupenthixol depot preparations in outpatient schizophrenics. II. Factor analysis of the  CPRS sub-scale for schizophrenia.
Eleven factors were obtained by factor analysing the CPRS results from a longitudinal treatment process study in chronic schizophrenics during maintenance phase. Such factors may give more reliable information than the single item. Two factors--"anxiety-depression-asthenia" and "psychotic" (psychotic schizophrenic symptoms and signs)--nonpsychotic rating of anxiety and depressive symptoms as well as definite psychotic-schizophrenic symptoms, respectively--demonstrated special value for the clinical work, i.e. being relevant instrument for monitoring a treatment process.
