title: Personality and social interactions in patients with acute brief psychoses.
abstract: Although a particularly vulnerable personality has been postulated by some authors as a pathogenetic factor in acute and transient psychotic disorders (ATPD) as introduced with ICD-10, little empirical work has been done on the subject. We therefore evaluated personality features and social interactions in a comparative study of patients with ATPD. We recruited all consecutive inpatients fulfilling the ICD-10 criteria of ATPD (F23) during a 5-year period, as well as control groups with "positive" schizophrenia (PS) and bipolar schizoaffective disorder (BSAD) matched for gender and age at index episode. For assessment of personality features and premorbid social contacts, we administered the NEO Five-Factor Inventory and a semi-structured interview. The assessment of the "Big Five" personality dimensions (neuroticism, extraversion, openness to experience, agreeableness, conscientiousness) with the NEO-FFI did not show any significant difference between ATPD patients and healthy controls. BSAD patients differed from mentally healthy controls on 2 of 5 subscales of the NEO-FFI (neuroticism, extraversion), but were otherwise indiscernible from ATPD patients and mentally healthy controls. In contrast, PS patients showed the most pronounced differences from the mentally healthy controls on the NEO-FFI, and had significantly less premorbid social interaction than the clinical controls. Within the limits of retrospective assessment, the present findings indicate that (1) patients with ATPD do not share the premorbid social impairment characteristic of schizophrenic patients and (2) the personality of patients with ATPD does not differ substantially from the general population.
