Introduction

The ICD-10 acute and transient psychotic disorders (ATPD, F23) without symptoms of schizophrenia are considered predominantly reactive psychotic disorders or affective pathology. However, negative symptoms of schizophrenia may be revealed in some of these cases after the psychotic reduction.

Objectives

To investigate the association between the developmental characteristics of psychosis and the negative symptoms detection after the psychotic reduction of ATPD without symptoms of schizophrenia.

Methods

68 adult inpatients with ATPD without symptoms of schizophrenia (F23.0) were examined. Negative symptoms were assessed with the PANSS negative symptom subscale (PANSS-NSS). The sample was divided into two groups: with PANSS-NSS score>14 (n=12) and with PANSS-NSS score≤14 (n=56), respectively. Clinical-psychopathological, psychometric and statistical methods were applied.

Results

The results of the study are presented in Table 1.

*p<0,001

Conclusions

The probability of negative symptoms detection in ATPD without symptoms of schizophrenia is relatively strongly associated with the family history of schizophrenia, poor premorbid social adaptation and functional decline prior to the psychotic onset.
