Introduction: The prognostic prediction of outcomes in individuals at clinical high-risk for psychosis (CHR-P) is still a significant clinical challenge. Among multiple baseline variables of risk calculator models, the role of ongoing pharmacological medications has been partially neglected, despite meta-analytical evidence of higher risk of psychosis transition associated with baseline prescription exposure to antipsychotics (AP) in CHR-P individuals. In particular, baseline AP exposure in CHR-P individuals may be considered as a functional equivalent of the psychometric transition to psychosis, as already postulated in the original 'Ultra High-Risk' model. Objectives: The main aim of the current study was to test the hypothesis that ongoing AP need at baseline indexes a subgroup of CHR-P individuals with more severe psychopathology and worse prognostic trajectories along a 1-year follow-up period. Methods: This research was settled within the 'Parma At-Risk Mental States' program. Baseline and 1-year follow-up assessment included the Positive And Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning (GAF). CHR-P individuals who were taking AP medications at entry were included in the CHR-P-AP+ subgroup. The remaining participants were grouped as CHR-P-AP-. The acquisition of drug and outcome information was collected both at baseline and across the follow-up period. Finally, logistic regression analyses with dichotomized 1-year outcome parameters (previously showing statistically significant differences in inter-group comparisons) as dependent measures and sociodemographic and clinical characteristics as independent variables were also performed. Results: Hundred and seventy-eight CHR-P individuals (aged 12–25 years) were enrolled (91 CHR-P-AP+, 87 CHR-P-AP-). Compared to CHR-P AP-, CHR-P AP+ individuals had older age, greater baseline PANSS 'Positive Symptoms' and 'Negative Symptoms' factor subscores and a lower GAF score. At the end of our follow-up, CHR-P-AP+ subjects showed higher rates of psychosis transition, new hospitalizations and urgent/non-planned visits compared to CHRP- AP- individuals. Conclusions: The current study suggests that AP need is a significant prognostic variable in cohorts of CHR-P individuals and should be included in the current risk calculators. In particular, the results of this study conducted in a realworld clinical setting indicate that the rate of CHR-P individuals who were already exposed to AP at the time of CHR-P status ascription was higher than those reported in recent meta-analyses on this topic. Moreover, our findings confirm that baseline AP prescription appears to increase psychotic transition risk. Disclosure of Interest: None Declared [ABSTRACT FROM AUTHOR]

Introduction: Depression is common in schizophrenia and is correlated with suicide risk and poor long-term outcomes. However, the presence of depressive symptoms is often underestimated in both research and treatment, particularly at the illness onset. Objectives: The goals of this study were: (a) to longitudinally observe anxious-depressive symptom levels in patients with First Episode Schizophrenia (FES) during a 24 months of follow-up period, and (b) to examine their associations with other psychopathology and the intervention patients received in an "Early Intervention in Psychosis" (EIP) program during the follow-up period. Methods: The Global Assessment of Functioning (GAF) and the Positive And Negative Syndrome Scale (PANSS) were completed by 159 FES patients both at baseline and across the follow-up. Data were analyzed by linear regression analysis and Spearman's coefficients. Results: Anxious-depressive symptoms had significant longitudinal associations with GAF deterioration and PANSS "Positive Symptoms", "Negative Symptoms" and "Disorganization" subscores. During the follow-up period, FES participants significantly improved the level of anxious-depressive symptoms. This was significantly associated with the number of case management and individual psychotherapy meetings the patient engaged in, as well as with lower antipsychotic doses prescribed during the follow-up period. Conclusions: In conclusion, anxious-depressive symptoms are prominent in FES and at the initial entry into EIP programs. Anxious-depressive symptom severity tends to diminish overtime, especially with the provision of specialized EIP treatments. However, since we did not have a control population studied in parallel, we cannot say whether these results are specific to the protocols of EIP programs or just to the intensity of engagement in care.

Introduction: Hedonic deficits have been extensively studied in schizophrenia, but little is known about their association with suicidal ideation in early psychosis. Along the clinical staging of psychosis, also Ultra-High Risk (UHR) individuals are characterized by hedonic deficits, which are currently considered as putative predictors of both psychosis conversion and poor social/role functioning. Objectives: The aim of this research was to examine the relationship between anhedonia and suicidal thoughts across a 2-year follow-up period in people with First Episode Psychosis (FEP) and at Ultra High Risk (UHR) of psychosis. Methods: Ninty-six UHR and 146 FEP, aged 13–35 years, completed the Comprehensive Assessment of At-Risk Mental States (CAARMS) and the Beck Depression Inventory-II (BDI-II). The BDI-II "Anhedonia" subscale score to assess anhedonia and the CAARMS "Depression" item 7.2 subscore to measure depression were used across the 2 years of follow-up. Hierarchical regression analyses were performed. Results: No difference in anhedonia scores between FEP and UHR individuals was found. In the FEP group, a significant enduring association between anhedonia and suicidal ideation was found at baseline and across the follow-up, independent of clinical depression. In the UHR subgroup, the enduring relationship between anhedonia and suicidal thoughts were not completely independent from depression severity. Conclusions: Anhedonia is relevant in predicting suicidal ideation in early psychosis. Specific pharmacological and/or psychosocial interventions on anhedonia within specialized EIP program could reduce suicide risk overtime.

Purpose: Males and females with First Episode Psychosis (FEP) usually tend to differ in psychopathology, clinical presentation and their longitudinal trajectory. This study aimed to examine the difference of effectiveness of specialized psychosocial and pharmacological treatments for FEP, focusing on various clinical and functioning outcomes across a 2-years follow-up period., Methods: The assessment included the CAARMS, the HoNOS, the PANSS and the GAF scale and was conducted at baseline and every 12 months., Results: 490 FEP patients (age: 12-35 years) were recruited. Of them, 363 completed the follow-up (132 females and 231 males). At baseline, males showed a higher prevalence rate of schizophrenia diagnosis (56.1% VS 43.8%; p = .008), whereas females a higher prevalence rate of affective psychosis (36.2% VS 23.3%; p = .005). Male participants also showed a more consistent substance abuse (46.9% VS 24.3%; p = .0001), lower years of education (11.26 ± 2.94 VS 11.88 ± 2.68; p = .013), and more striking behavioral manifestations (4.06 ± 2.36 VS 3.39 ± 2.58; p = .003) compared to women. Our 2-year outcome parameter results showed a higher incidence of functional remission over time in females compared to males (49.2% VS 39.0%; p = .028), together with a decreasing trend in new hospitalization rates (17.8% VS 26.9%; p = .089). Independently from sex, our results also showed a statistically significant reduction in the prescription of psychotropic medications and through the increase of all psychosocial interventions, although more evident in males., Conclusion: These results suggested that specialized interventions for FEP are overall effective in both treated subgroups. Additionally, FEP women specifically showed higher rates of improvement in functional outcome variables over time when compared to males., Competing Interests: Declarations.

Introduction: Suicidal ideation has high rates among individuals at Clinical High Risk for Psychosis (CHR-P). CHR-P mental states are currently defined as attenuated psychotic symptoms, brief intermittent psychotic symptoms, or genetic risk and functioning deterioration syndrome. However, the relationship between psychotic experiences and suicidality in CHR-P subjects is still not fully understood. Research emphasizes the need to address suicidality in CHR-P individuals due to its incidence and severe socio-economic impact. This study aimed to assess the baseline prevalence and 2-year incidence rates of suicidal thinking and behaviors in an Italian CHR-P sample, investigate the stability of suicidal ideation over 2 years, and examine its associations with treatment outcomes, sociodemographic characteristics, and clinical factors., Methods: CHR-P participants were treated in an "Early Intervention in Psychosis" program and completed the PANSS and the GAF scale at baseline and every 12 months., Results: 180 CHR-P individuals were enrolled (92 with suicidal ideation [SI+]). SI+ subjects had a higher baseline prevalence of past suicide attempts. Over 2 years, a decrease in suicidal ideation severity was observed in the total group. Longitudinal improvement in disorganized symptoms was a key predictor of the decrease in suicidal ideation. Participants with a history of suicide attempts were more likely to attempt again., Conclusion: Addressing disorganization is crucial for suicide prevention in the CHR-P population. Continuous risk monitoring and preventive actions are needed for those with past suicide attempts., (© 2024 The Author(s).

Purpose: Diagnostic stability for people with First Episode Psychosis (FEP) is essential for treatment, but it remains poorly investigated, especially in adolescents and within a prospective design. The aims of this research were: (a) to examine diagnostic change in Italian adolescents with FEP treated within an "Early Intervention in Psychosis" program during a 2-year follow-up period and (b) to investigate any sociodemographic and clinical predictors at baseline., Methods: At baseline, 66 adolescents with FEP was recruited. Their primary diagnosis was formulated both at baseline and at the end of follow-up. At presentation, FEP adolescents completed the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA). As for diagnostic stability, the Kappa statistic was calculated. The associations of diagnostic change with baseline clinical and sociodemographic features were analyzed using a logistic model with the diagnostic shift as dependent variable. A propensity score was finally calculated based on logistic analysis results., Results: 38 (57.6%) FEP adolescents changed their opening diagnosis. The highest prospective diagnostic stability was for initial diagnosis of schizophrenia (95.4%) and affective spectrum psychoses (75%). Diagnostic instability was high for opening diagnosis of psychosis not otherwise specified, brief psychosis and schizophreniform disorder (100%). The best predictors of diagnostic change were fewer years of education, shorter duration of untreated psychosis and higher baseline levels of psychiatric symptoms., Conclusion: Diagnostic stability is crucial for treatment and clinical decision making. Addressing instability in FEP diagnoses is an important challenge for future diagnostic development in early psychosis, especially in adolescence., Competing Interests: Declarations.

Aim: Although the presence of psychotic symptoms has been widely recognized in Borderline Personality Disorder (BPD), no study previously investigated cognitive Basic Symptoms (BS) and their clinical implications in patients with BPD., Methods: This cross-sectional study specifically examined the prevalence of COGDIS (cognitive disturbances) BS criteria in 93 help-seeking outpatients with BPD by using the Schizophrenia Proneness Instrument-Adult Version (SPI-A). We then explored associations of COGDIS with personality traits, functioning and core psychopathological features of BPD., Results: The prevalence rates of COGDIS criterion were 62.4%. BPD patients meeting COGDIS criteria reported higher levels of schizotypal personality traits, dissociative experiences and work/social functional impairment compared to individuals without COGDIS criteria. Furthermore, the number of cognitive BSs showed a positive correlation with severity levels of schizotypy., Conclusions: Cognitive BS are common in BPD. Cognitive disturbances are associated with schizotypal personality traits and specific clinical features. The presence of cognitive BSs may identify a more severe subgroup of patients with BPD, potentially vulnerable to psychotic symptoms and reliably identifiable through assessment of schizotypal traits., (© 2024 John Wiley & Sons Australia, Ltd.)
