López-Díaz A, et al. - In this prospective, 2-year, observational study involving 68 patients presenting with a first-episode acute and transient psychotic disorders (ATPD), prospective temporal stability of ATPD was examined. Further, an assessment was done to determine the clinical, psychopathological, or sociodemographic characteristics that could predict ATPD diagnostic stability. At the end of the follow-up period, researchers observed a diagnostic stability rate of as high as 55.9% (n = 38). Upon multivariate analysis, diagnostic stability was noted to be independently significantly correlated with baseline presence of motility disturbances, the absence of hallucinations, and the absence of schizophrenic features. These findings suggested the possible utility of assessment of these psychopathological features for early identification of individuals whose initial ATPD diagnosis will remain stable over time.
