Sintomatologia delle psicosi maggiori: analisi
fattoriale di 1891 soggetti psicotici
Major Psychoses Symptomatology: Factor Analysis of 1891 Psychotic Subjects
Background and objectivesCurrent nosography classifies major psychoses as separate disorders, but their symptomatological presentation during illness episodes largely overlaps and diagnoses may change during lifetime. Few analyses of major psychoses symptomatology have been performed so far because of the large number of subjects needed to obtain stable factors. The purpose of this study was therefore to identify the symptomatologic structure common to major psychoses based on life-time symptoms.
Methods
One thousand eight hundreds and ninety one inpatients affected by schizophrenic
(n = 455), bipolar (n = 639), major depressive (n = 487), delusional (n =
108) and psychotic not otherwise specified disorder (n=201) were rated for
lifetime symptoms using the Operational Criteria checklist for psychotic illness
(OPCRIT) and included in a factorial analysis.
Results
Four factors were obtained, the first consisted of excitement symptoms,
the second comprised psychotic features (delusions and hallucinations), the
third comprised depression and the fourth disorganization.
Conclusions
When scored by the OPCRIT checklist, major psychoses symptomatology results
composed of excitement, depressive, delusion and disorganization symptoms.
