IntroductionSelf Disorders (SDs) are regarded as the subjective phenotype of Schizophrenia vulnerability. The EASE (Examination of Anomalous Self-Experiences) scale is the most detailed and widely used instrument to investigate SDs, but it requires long administration times and specific training. The IPASE (Inventory of Psychotic-like Anomalous Self-Experiences) scale might be a self-administered instrument of widespread use for an easier SDs investigation.ObjectivesThe present study was aimed at validating the Italian version of IPASE, testing its internal consistency and usability for a first level SDs survey. A secondary objective was to confirm the correlations between IPASE, EASE, main symptom dimensions, subjective bodily experiences, symptoms of schizophrenic autism as well as levels of global functioning.MethodsFifty patients with Schizophrenia were administered the IPASE scale in its Italian version, the Examination of Anomalous Self-Experiences scale (EASE), the Positive And Negative Symptoms Scale (PANSS), the Social and Occupational Functioning Assessment Scale (SOFAS) to assess global functioning, the Autism Rating Scale (ARS) and the Abnormal Bodily Phenomena questionnaire (ABPq). The internal consistency of IPASE in its Italian version was investigated and the correlations between IPASE, EASE, ABP, ARS, PANSS and SOFAS were explored.ResultsThe internal consistency of the Italian version of IPASE was high (α 0.97). The IPASE and EASE total scores were positively correlated with each other, as were many of the conceptually related subdomains of both scales. The IPASE score was negatively correlated with global functioning (SOFAS) and positively correlated with total PANSS scores and with PANSS negative domain. Moreover, the IPASE total score was positively correlated with autism dimension (ARS), while anomalies in subjective experience of the lived body were coherently correlated with higher scores in IPASE “somatization” subdomain.Conclusions The IPASE may be an easy instrument with high internal consistency for an initial investigation of SDs. IPASE domains appear to be correlated with the SDs investigated through EASE and with the main symptomatologic dimensions of Schizophrenia, in particular with negative symptoms. IPASE might also be a useful instrument for a first level investigation of subjective experiences concerning intersubjectivity and bodily dimensions.SDs are confirmed to be a core feature of the schizophrenia psychopathology, with a adverse impact on global functioning.Disclosure of InterestNone Declared

Introduction Language and conversation are deeply interrelated: language is acquired, structured, practiced in social interactions and linguistic resources (specifically syntactic, prosodic and pragmatic aspects) contribute to finely tuning turn-taking. Nevertheless, most studies focused on verbal aspects of speech in schizophrenia, with scant attention to their relation to conversation, where language is experienced at most. Objectives The present study was aimed at investigating a possible association between language impairment and conversational characteristics in a sample of clinically stable patients diagnosed with schizophrenia (N = 35, ages 18-65). Methods A spontaneous speech sample was recorded. For the assessment of language skills, the Scale for the Assessment of Thought, Language and Communication (TLC) and the Clinical Language Disorder Rating Scale (CLANG) were used, while conversational variables were extracted with an innovative method of semi-automatic analysis. The possible associations were investigated through the Pearson Correlation. Results Figure 1 represents graphically the correlational matrix between conversational variables and linguistic scale scores. In the heatmap, blue means negative and red positive correlations, the stronger the colour, the larger the correlation magnitude. Moreover, the significant associations are indicated with stars. Conclusions The results suggest that in schizophrenia spectrum disorders the disturbances of language, at a syntactic, prosodic and pragmatic level, have significant impact on communicative interaction. Thus, conversation analysis might be a promising method to quantify objectively communicative impairment with the benefit of representing an ecological assessment, examining the performance of patients in the real situation of language use, which is social interaction.
