Source monitoring deficits in inpatients with schizophrenia and bipolar disorder in acute disorder phase

BACKGROUND: Several studies highlighted schizophrenic and bipolar disorders similar cerebral activation deficit pat-terns. Source information recall deficit is one of the several problems found in people with schizophrenia.METHODS: We wanted to test source monitoring deficit e ven in i ndividuals w ith b ipolar disorder, c omparing both hospitalized schizophrenic and bipolar group in acute disorder phase (N.=36) with controls without psychiatric disorders (N.=28). Source monitoring is the ability to remember from where the information is acquired. As a matter of fact, for the evaluation of source monitoring deficits we assessed all the three groups with source monitoring tasks. Subsequently we tested our hypothesis through a one-way Anova Test with Jamovi suite. The source monitoring task is composed of four several conditions: "Picture," "Hear," "Self-generated" and "New." All participants were asked to recall the type of target word presentation (image, heard, read) and fill out a grid with the different options. In "New" phase, participants had to report any word that was present in the grid but that was absent during the first phase of the task.RESULTS: Results showed no statistically significant differences between schizophrenic and bipolar participants. As a result, source monitoring deficits are a common deficit area among these two clinical conditions. Instead, when the comparison is made between experimental and control groups there are statistically significant results in different domains of source monitoring tasks. CONCLUSIONS: Participants with schizophrenia or bipolar disorders are less accurate to recall source information in "Picture" condition compared to healthy controls.(Cite this article as: Nobile E, Cicinelli G, Santarella F, Tonella E, Vischia F, Keller R.
