RESUMEN

This data resource provides evidence concerning the prevalence of perceptual alterations of emotional faces amongst individuals experiencing symptoms of insomnia, anxiety, depression, mania, psychotic experiences, and schizotypal tendencies. More specifically, we explored the categorisation accuracy (whether the displayed emotion was correctly identified), misperception (which emotion an incorrect judgment was perceived to be), intensity (extent of the emotion signal strength) and emotional valence (the extent and direction of perceived affect) of six facial expressions of emotion from the Karolinska Directed Emotional Faces database. Complete data from N = 572 respondents are included. The dataset is available to other researchers and is provided on Figshare. Information concerning the data records, usage notes, code availability and technical validation are presented. Finally, we present demographic and correlational data concerning psychiatric symptoms and alterations in the perception of emotional faces.

RESUMEN

Self-mutilation attempts are common in psychiatric practice. One form of self-harm, genital self-mutilation (GSM), is less common but may have severe consequences. GSM acts can occur in different diagnoses such as personality disorders, substance abuse disorders, obsessive-compulsive disorders, and psychotic disorders. When GSM is performed due to psychotic symptoms, the clinical picture is called Klingsor Syndrome. GSM is often associated with severe psychosis and often accompanied by religious delusions. In our article, we discussed a case of schizophrenia with penile autoamputation due to religious delusions. A 28-year-old male patient was admitted to our hospital after penile autoamputation. After surgical interventions, the patient's follow-up continued in our clinic. The patient had auditory hallucinations, delusions of persecution, and sinfulness. His symptoms improved after antipsychotic treatment. It is important to identify the risk factors of Klingsor Syndrome, which is a rare but serious condition, and to intervene early in these patients. Keywords: Self-mutilation, Psychosis, Self-injurious Behavior.

RESUMEN

AIM: Functional Management and Recovery is a standardized Psychoeducational Intervention, derived from "Integro", an effective salutogenic-psychoeducational intervention for people in recovery journey, designed to improve recovery and functioning of individuals with psychotic disorders in Psychiatric Residential Facilities (PRFs). The aim of this study is to evaluate the primary and secondary outcomes of this intervention elaborated specifically for PRFs where evidence based structured interventions seem rare and desirable. METHODS: 66 individuals with psychotic disorders were recruited in 9 PRFs dislocated in the North, Center and South Italy and 63 underwent a multicenter follow-up study with a two time-point evaluation (t0, pre-treatment and t1, 6 months; ). At each time point, social functioning was assessed as primary outcome by the Personal and Social Performance scale (PSP); furthermore, psychopathological status was assessed by Brief Psychiatric Rating Scale (BPRS), Recovery by Recovery Assessment Scale (RAS), Cognitive Functioning by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Stress management by Stress-Scale, Cognitive Flexibility by Modified Five-Point Test (M-FPT), Emotional Intelligence by Emotional Intelligence Index (EI-I), the PRF Atmosphere and the Opinion of users about the PFR by an ad hoc questionnaire. The Abilities Knowledge, the Utility and Pleasantness of sessions were measured by an ad hoc list of items. RESULTS: 63 individuals out of 66, 52 (82,5%) affected by schizophrenia and 11 (17,5%) by bipolar I disorder with psychotic symptoms according to DSM-5-TR completed the study. At the end of the study, 43 (68,3%) were male, 57 (90.5%) were single, 5 (7.9%) engaged, 1 (1.6%) married; 45 (71.4%) unemployed. The total scores of PSP, RAS, BPRS, BANS, Stress management, Abilities Knowledge, Utility and Pleasantness of sessions showed a statistically significant improvement at t1 vs. t0. Two sub-scales out of 5 of M-FPT showed a statistically significant improvement. The Emotional Intelligence, the Unit Atmosphere and the Opinion of Users about PFR improved without statistical significance. Six months after the end of the follow-up study 22 individuals of the sample were dismissed with a very high turnover. CONCLUSIONS: After a six-month follow-up (a short period of time), these results showed improvement in functioning, the primary outcome, as well as in the following secondary outcome variables: RAS, BPRS, BANS, Stress management, Abilities Knowledge, two sub-scales out of 5 of M-FPT, Utility and Pleasantness of sessions. Overall, a remarkable impact of psychoeducational structured intervention on the key Recovery variables is observed. Further studies are needed to address extent and duration of these improvements.

RESUMEN

BACKGROUND: Today, addressing issues related to the use of virtual space is of paramount importance due to its significant impact on mental well-being. This is especially crucial when the research community consists of teenagers who are cyber bullies or their victims who have higher vulnerability. The aim of the present study was to investigate the mediating role of alexithymia in the relationship between cyberbullying and psychotic experiences in adolescents. METHODS: The research method employed in this study was correlational, and the study population consisted of all male and female middle school students in Tehran during the 2022-2023 academic years. As for data collection, the Cyber-Bullying/Victimization Experiences questionnaire, Community Assessment of Psychic Experiences, and the Toronto Alexithymia scale were applied. A total of 602 samples were gathered by using multi-stage cluster sampling from Tehran in Iran. Four selection of the sample, the regions in Tehran were selected randomly according to the geographical directions of them and then some schools and classes were chosen randomly. Sample was included in the analysis after data entry into SPSS software and subsequent structural equation modeling using AMOS software. RESULTS: According to the findings, cyberbullying (ß = 0.11,p < 0.05) and cyber victimization(ß = 0.41, p < 0.001) were significant predictors of psychotic experiences. Alexithymia partially mediated the relationship between cyberbullying and psychotic experiences with the mediation effect of 0.28 and cyber victimization and psychotic experiences with the mediation effect of 0.18. CONCLUSIONS: These findings underscore the importance of identifying cyber victims or cyberbullies in order to prevent alexithymia and psychotic experiences in future, in order to prevent more serious problems and becoming psychotic. TRIAL REGISTRATION: The goals and conditions of this research were investigated and approved by the Ethics Committee of Alzahra University in Tehran (code: ALZAHRA.REC.1402.055) on 13th September 2023.

RESUMEN

BACKGROUND: Impulsivity is associated with serious detrimental consequences on physical, mental, behavioral and social aspects of health among patients with psychosis. The present prospective 12-month follow-up study aimed to determine the prevalence of highly impulsive individuals among Ultra High Risk (UHR) patients, how impulsivity evolves over the follow-up period, and whether impulsivity impacts clinical, psychological and functional outcomes in this population. METHOD: UHR patients were invited to complete a battery of measurements at three-time points: at baseline, and at 6 and 12 months of follow-up. Impulsivity was assessed using both behavioral (the Wisconsin Card Sorting Test, WCST) and self-report (the Barratt Impulsiveness Scale, BIS-11) measures. RESULTS: Findings showed that at 6 months of follow-up, higher 6-month BIS-11 attentional and motor impulsivity were significantly associated with lower quality of life and greater general psychological distress. In addition, higher baseline BIS-11 motor impulsivity significantly predicted more severe positive psychotic symptoms at 12 months of follow-up. However, WCST scores did not show any significant associations with study variables at the different times of follow-up. CONCLUSION: Interventions targeting impulsivity in UHR individuals could help decrease psychological distress and positive psychotic symptoms' severity, as well as improve quality of life in UHR individuals.

RESUMEN

Little is known about the individual course of suicidal ideations and attempts (i.e., suicidality) after treatment initiation. We examined the trajectories of suicidality and associated risk factors over a 2-year early intervention program for first-episode psychosis in 450 patients (age range 18-35 years at admission) consecutively admitted from 2003 to 2017. Suicidality was assessed via systematic file review, while sociodemographic and clinical variables were assessed at admission. Latent class growth modelling identified three trajectories: low (69.6 %), initially high (22.9 %), and persistently high (7.6 %) suicidality. Patients who were younger, lived alone and were diagnosed with affective psychosis were significantly more likely to follow the initially high trajectory. Patients who attempted suicide up to 3 months before admission, lived alone and presented lower levels of the PANSS excited factor were significantly more likely to follow the persistently high trajectory. Attempting suicide up to 3 months before admission distinguished persistently high and initially high suicidality trajectories. Suicide risk during early intervention program for first-episode psychosis is heterogenous, with acute and enduring suicidal risk, suggesting the need to adapt suicide prevention strategies to these different risk profiles.

RESUMEN

Facial emotion perception deficits, a possible indicator of illness progression and transdiagnostic phenotype, were examined in high-risk psychosis (CHR) patients through a systematic review and meta-analysis of 35 studies (2567 CHR individuals, 1103 non-transitioned [CHR-NT], 212 transitioned [CHR-T], 512 first-episode psychosis [FEP], and 1936 healthy controls [HC]). CHR showed overall (g = -0.369 [95 % CI, -0.485 to -0.253]) and specific impairments in detecting anger, disgust, fear, happiness, neutrality, and sadness compared to HC, except for surprise. FEP revealed a general deficit than CHR (g = -0.378 [95 % CI, -0.509 to -0.247]), and CHR-T displayed more pronounced baseline impairments than CHR-NT (g = -0.217 [95 % CI, -0.365 to -0.068]). FEP only exhibited a poorer ability to perceive fear, but not other individual emotions, compared to CHR. Similar performances in perceiving individual emotions were observed regardless of transition status (CHR-NT and CHR-T). However, literature comparing the perception of individual emotions among FEP, CHR-T, and CHR is limited. This study primarily characterized the general and overall impairments of facial emotion perception in CHR which could predict transition risk, emphasizing the need for future research on multimodal parameters of emotion perception and associations with other psychiatric outcomes.

RESUMEN

INTRODUCTION: Treatable mental disorders, such as psychotic, major depressive disorder (MDD), and bipolar disorder (BD), contribute to a substantial portion of suicide risk, often accompanied by neurocognitive deficits. We report the association between cognitive function and suicidal ideation/suicide attempts (SI/SA) in individuals with schizoaffective disorder, BD, and MDD. METHODS: A systematic search was conducted on PubMed, Ovid and Scopus databases for primary studies published from inception to April 2024. Eligible articles that reported on the effect size of association between cognition and SI/SA were pooled using a random effects model. RESULTS: A total of 41 studies were included for analysis. There was a negative association between executive functioning and SI/SA in schizoaffective disorder (SA: Corr = -0·78, 95 % CI [-1·00, 0·98]; SI: Corr = -0·06, 95 % CI [-0·85, 0·82]) and MDD (SA: Corr = -0·227, 95 % CI [-0·419, -0·017]; SI: Corr = -0·14, 95 % CI [-0·33, 0·06]). Results were mixed for BD, with a significant positive association between SA and global executive functioning (Corr = 0·08, 95 % CI [0·01, 0·15]) and negative association with emotion inhibition. Mixed results were observed for processing speed, attention, and learning and memory, transdiagnostically. LIMITATIONS: There is heterogeneity across sample compositions and cognitive measures. We did not have detailed information on individuals with respect to demographics and comorbidities. CONCLUSIONS: We observed a transdiagnostic association between measures of cognitive functions and aspects of suicidality. The interplay of cognitive disturbances, particularly in reward-based functioning, may underlie suicidality in individuals with mental disorders. Disturbances in impulse control, planning, and working memory may contribute to self-injurious behavior and suicide.

RESUMEN

BACKGROUND: Impaired gamma band oscillation, specifically 40-Hz auditory steady state response (ASSR) has been robustly found in schizophrenia, while there is relatively little evidence characterizing the ASSR before full-blown psychosis. OBJECTIVE: To characterize gamma-band ASSR in populations at clinical high-risk for psychosis (CHR). METHODS: One hundred and seven CHR subjects and sixty-five healthy control (HC) subjects were included and completed clinical assessments, the ASSR paradigm of electroencephalography (EEG) and cognitive assessments. Both indices of event-related spectrum perturbation (ERSP) and intertrial coherence (ITC) in response to 20-Hz, 30-Hz and 40-Hz click sounds were respectively qualified and compared between these two groups, as well as the relationship to clinical psychopathology and cognitive function was assessed. RESULTS: At 40-Hz click sounds, ERSP in HC group (1.042 ± 0.047) was statistical significantly increased than that in CHR group (0.873 ± 0.036) (p = 0.005)；at 30-Hz, ERSP in HC group (0.536 ± 0.024) was increased than that in CHR group (0.483 ± 0.019), but the difference was trend statistical significance (p = 0.083)；at 20-Hz, ERSP in HC group (0.452 ± 0.017) was not different significantly from CHR group (0.418 ± 0.013) (p = 0.104). ERSP of the HC group was the highest at 40-Hz click sounds, followed by 30-Hz, and the lowest at 20-Hz. The difference between any two of the three ERSP showed statistical significance (30-Hz vs. 40-Hz: p < 0.001; 20-Hz vs. 40-Hz: p < 0.001；20-Hz vs. 30-Hz: p = 0.003). Similarly, ERSP of the CHR group was the highest at 40-Hz click sounds, followed by 30-Hz, and the lowest at 20-Hz. The difference between any two of these three ERSP showed statistical significance (30-Hz vs. 40-Hz: p < 0.001; 20-Hz vs. 40-Hz: p < 0.001；20-Hz vs. 30-Hz: p = 0.002). A statistically significant small positive correlation of 40-Hz ERSP with signal processing speed score was observed in the HC group (ρ = 0.27, p = 0.029). A statistically significant small negative correlation of 40-Hz ERSP with visual learning score was observed in the CHR group (ρ = -0.22, p = 0.023). CONCLUSION: Impaired 40-Hz but undamaged hierarchical organization mode of auditory steady state presented in the CHR populations. Abnormal 40 Hz ASSR for CHR might be associated with cognitive functions, such as information processing speed and visual memory.

RESUMEN

Insomnia and suicidal ideation (SI) are common in schizophrenia, including in individuals at clinical high-risk for psychosis (CHR-P). Previous studies have found associations between sleep disturbance, SI, and psychopathology in schizophrenia. We explored these associations in a CHR-P cohort. We leveraged data from CHR-P individuals in the North American Prodrome Longitudinal Studies (NAPLS-3) (n = 688) cohort. We investigated relationships between sleep disturbance (Scale of Prodromal Symptoms [SOPS]; Calgary Depression Scale for Schizophrenia [CDSS], and the Pittsburgh Sleep Quality Index [PSQI]), suicidal ideation (CDSS), and psychosis-risk symptoms. The prevalence of terminal insomnia, sleep disturbance, and SI in NAPLS3 was 25 %, 69 %, and 29 %, respectively. After controlling for potential confounders, multiple indices of sleep disturbance (SOPS, PSQI: OR = 1.05-1.40) were significant indicators of concurrent SI. Terminal insomnia was not associated with conversion to psychosis. Multiple indices of sleep problems were associated with higher total and subscale psychosis-risk symptom scores (ß = 0.09-0.39). Sleep problems are prevalent and associated with SI and more severe psychosis-risk symptoms in CHR-P individuals. These findings underscore the importance of designing longitudinal intervention studies to investigate whether the treatment of sleep disturbances may reduce suicidality and symptoms in this population.

RESUMEN

ABSTRACT: The psychopathological manifestations associated with substance use, including induced psychotic experiences, are increasingly relevant but not well-understood within the medical community. Novel psychoactive substances and potentiated old compounds like cannabis and cocaine have emerged as a global concern, especially among adolescents and young adults. Transition rates from substance-induced psychosis (SIP) to persistent psychosis are significant, particularly in cases of cannabis-induced psychosis. Scientific inquiry into induced psychotic phenomena has revealed differences between SIP and primary psychotic disorders, highlighting the risk factors associated with each. The concept of exogenous psychosis, including its toxic variant known as lysergic psychoma, provides valuable insights into the role of external factors in psychosis development. A phenomenological approach characterizes this disruption in perception as a shift in temporal and spatial dimensions, leading to auditory and visual hallucinations. The "twilight state" of consciousness plays a crucial role in the transition from substance use to psychosis, with implications for spatiality, intersubjectivity, and temporality. This complex path to psychosis challenges traditional diagnostic models and underscores the need for a more nuanced understanding of substance-induced psychopathological experiences.

RESUMEN

BACKGROUND: Postpartum psychosis (PP) is a psychological emergency requiring rapid intervention, hospitalization and psychiatric management. However, PP has been neglected in the postpartum literature. Understanding the detrimental consequences of childhood trauma across mother's life span is crucial to prevent this serious condition. The study's objectives were to demonstrate the relationship between childhood trauma and postpartum psychotic experiences (PPEs) and to look over the mediating role of postnatal depression (PD) and anxiety (PA) in this relationship. METHODS: This cross-sectional study, which enrolled 438 postpartum females 4-6 weeks after delivery (mean age: 31.23 ± 5.24 years), was carried out from September 2022 to June 2023. The Arabic validated versions of the Postpartum Psychotic Experiences Scale, the Edinburgh Postnatal Depression Scale, the Perinatal Anxiety Screening Scale, and the Child Abuse Self Report Scale were used. RESULTS: Both PD and PA partially mediated the correlation between psychological abuse and PPEs, and fully mediated the association between neglect and PPEs. Higher psychological abuse and neglect were significantly associated with higher PD (Beta = 1.11) and PA (Beta = 3.94), higher PD (Beta = 0.84) and PA (Beta = 0.26) were significantly associated with higher PPEs in both models, whereas greater child psychological abuse (Beta = 1.37) (but not neglect) was directly and strongly correlated with higher PPEs in all models. CONCLUSION: The significant mediating effect of PA and PD on the association between childhood adversities and PPEs among postpartum females may offer additional therapeutic avenues to help attenuate various postpartum mental health issues and their potential serious risks on both mother and child.

RESUMEN

The clinical features of neuropsychiatric systemic lupus erythematosus (NPSLE) are heterogeneous. Furthermore, therapeutic decision-making for NPSLE depends on the recognition of clinical syndromes that have not been sufficiently studied. This report describes the case of a 36-year-old woman with NPSLE who exhibited severe cognitive dysfunction and affective psychosis with persistent nihilistic delusions such as those described in the Cotard delusion. The patient insisted for several months that she was already dead. CSF analysis showed elevated levels of anti-ribosomal P antibodies and a positive determination of oligoclonal bands. Additionally, 18F -FDG PET/CT imaging revealed severe bilateral frontal hypermetabolism suggestive of brain inflammation and occipital hypometabolism. Results from the Systematic Lupus Erythematosus Disease Activity Index 2000 and the Systemic Lupus Erythematosus Disease Activity Score were consistent with an active state of the immunological disease. We then determined by an algorithm that this neuropsychiatric event could be attributed to the activity of the underlying immunological disease. Despite immunosuppressive and symptomatic treatment, only a partial improvement in cognition was achieved. The psychopathological features of the Cotard delusion remained unchanged 4 months after onset. However, we observed rapid remission of affective psychosis and significant improvement in cognition following electroconvulsive therapy. Subsequent follow-up examinations showed a sustained remission. This case describes a protracted form of the Cotard delusion, the diagnostic challenges that arise in the context of SLE, and treatment dilemmas that necessitate collaboration between neurology, psychiatry, and rheumatology.

RESUMEN

Cognitive behaviour therapy for psychosis (CBTp) should be offered to patients receiving psychiatric inpatient care, yet very little is known about patients' perspectives on this. The aim of this study was to examine patients' experiences of a CBTp-informed intervention delivered in inpatient settings. We recruited 10 participants from the intervention arm of a randomised controlled trial examining the feasibility and acceptability of a CBTp-informed intervention for psychiatric inpatient settings. We undertook semistructured interviews examining their experiences of the intervention and analysed them using thematic analysis. The study was conducted in partnership with a coproduction group of key stakeholders (people with lived experience, family and carers, and clinicians). The intervention was found helpful by almost all participants, and all participants would recommend it to others in similar situations to themselves. The results demonstrated that participants valued the therapist's professionalism and emphasised the importance of the therapeutic relationship. Participants highlighted the importance of the therapy focusing on navigating admission and developing skills to manage the crisis experience so they could return to their normal lives. Participants described challenges to having psychological therapy in the acute crisis context including therapy interruptions and ongoing distressing experiences of psychosis. The study demonstrated the importance of prioritising the therapeutic relationship, that therapy was a valued process to navigate admission and discharge, but that some environmental and patient-level challenges were present. Further research is needed to explore inpatients' experiences of psychological interventions in this setting. TRIAL REGISTRATION: ISRCTN trial registry: ISRCTN59055607.

RESUMEN

Patients with mental illnesses, particularly psychosis and obsessive‒compulsive disorder (OCD), frequently exhibit deficits in executive function and visuospatial memory. Traditional assessments, such as the Rey‒Osterrieth Complex Figure Test (RCFT), performed in clinical settings require time and effort. This study aimed to develop a deep learning model using the RCFT and based on eye tracking to detect impaired executive function during visuospatial memory encoding in patients with mental illnesses. In 96 patients with first-episode psychosis, 49 with clinical high risk for psychosis, 104 with OCD, and 159 healthy controls, eye movements were recorded during a 3-min RCFT figure memorization task, and organization and immediate recall scores were obtained. These scores, along with the fixation points indicating eye-focused locations in the figure, were used to train a Long Short-Term Memory + Attention model for detecting impaired executive function and visuospatial memory. The model distinguished between normal and impaired executive function, with an F1 score of 83.5%, and identified visuospatial memory deficits, with an F1 score of 80.7%, regardless of psychiatric diagnosis. These findings suggest that this eye tracking-based deep learning model can directly and rapidly identify impaired executive function during visuospatial memory encoding, with potential applications in various psychiatric and neurological disorders.

RESUMEN

PURPOSE: This study proposed and evaluated a theoretical model for exploring the relationships between neurocognition, self-defeatist beliefs, experiential negative symptoms, and social functioning in individuals with chronic schizophrenia. METHOD: The study recruited 229 individuals given a diagnosis of schizophrenia and schizoaffective disorders from outpatient clinics and the day ward of a mental health hospital. After informed consent was obtained, the participants underwent assessments using the backward digit span, the digit symbol, and measures of self-defeatist beliefs, experiential negative symptoms, and social functioning. A structural equation model was applied to assess the fitness of the hypothesized model, with indices such as the goodness-of-fit index, comparative fit index, root mean square error of approximation, and standardized root mean square residual being used for model evaluation. RESULTS: The hypothesized model had an adequate fit. The study findings indicated that neurocognition might indirectly influence self-defeatist beliefs through its effect on experiential negative symptoms. Contrary to expectations, the study did not observe a direct influence of neurocognition, self-defeatist beliefs, or negative symptoms on social functioning. The revised model revealed the role of experiential negative symptoms in mediating the association between neurocognition and social functioning. However, self-defeatist beliefs did not significantly affect social functioning. DISCUSSION: Before modifying negative thoughts, enhancement of self-awareness ability can help improve negative symptoms and thereby improve the performance of social functions. Future research should develop a hierarchical program of negative symptoms, from cognition rehabilitation to enhancement of self-awareness, and end with modifying maladaptive beliefs.

RESUMEN

INTRODUCTION: Neuropsychiatric symptoms may impact prognosis in individuals with mild cognitive impairment (MCI); however, data on frequency of psychotic symptoms are sparse. METHODS: We searched MEDLINE, EMBASE, PsychoINFO from inception to June 2023. We included studies reporting patients with MCI prevalence of (delusions and/or hallucinations. Random effects model were performed to estimate the prevalence, and subgroup and meta-regression analyses were performed to explore heterogeneity. RESULTS: Of 3145 records identified, 36 studies were included, enrolling 20,426 patients. Overall prevalence of hallucinations was 1.78 % (95 % CI, 1.17 - 2.71) and delusions 3.84 % (95 % CI, 2.71 - 5.42), both with significant heterogeneity (/2 = 90 %). Prevalence of hallucinations and delusions were lower when measured by NPI scales and in population-based samples. DISCUSSION: Delusions and hallucinations occur in MCI patients at low rates. Prevalence can be partially explained by the assessment method, sample source and study heterogeneity.

RESUMEN

BACKGROUND: We aimed to explore gender-related differences in the associations of insight impairment with clinical symptoms, metacognition, and social cognition in psychosis. METHODS: Regression analysis of several clinical insight dimensions was conducted on the data from 116 men and 56 women with first-episode psychosis. Various clinical symptoms and measures of metacognition and social cognition were entered as predictors. RESULTS: In both men and women, delusions emerged as a strong predictor of all insight dimensions, and verbal hallucinations as a strong predictor of symptom relabelling. In men, certain negative symptoms as well as self-certainty, lack of self-reflectiveness, impaired theory of mind, attributional biases, and a jumping-to-conclusions bias were additional predictors of poor insight, while good insight was associated with depression, anxiety, avolition, blunted affect, and impaired emotional recognition. In women, poor insight was associated with a self-serving/externalising bias, impaired emotional recognition, and attention disorders. CONCLUSIONS: Poor insight in first-episode psychosis is strongly linked to deficits in metacognition and social cognition, with marked differences between men and women with respect to the specific skills involved in the impairment. Meanwhile, good insight is linked to a variety of affective manifestations in men. These findings suggest new avenues for more targeted cognitive interventions to improve clinical insight in psychosis.

RESUMEN

BACKGROUND: Psychotic-like experiences (PLEs) are subtle, subclinical perturbations of perceptions and thoughts and are common in the general population. Their characterisation and unidimensionality are still debated. METHODS: This study was conducted by the Electronic-halluCinations-Like Experiences Cross-culTural International Consortium (E-CLECTIC) and aimed at measuring the Community Assessment of Psychic Experiences (CAPE) factorial structure across five European countries (Belgium; Czech Republic, Germany; Greece, and Spain) and testing the adequacy of the unidimensional polytomous Rasch model of the tool via Partial Credit Model (PCM) of the CAPE to detect people with a high risk for developing psychosis. RESULTS: The sample included 1461 participants from the general population. The factorial analysis confirmed the best fit for the bifactor implementation of the three-factor model, including the positive, negative and depressive dimensions and a general factor. Moreover, the unidimensional polytomous Rasch analysis confirmed that CAPE responses reflected one underlying psychosis proneness. CONCLUSIONS: The study proved that the CAPE measures a single latent dimension of psychosis-proneness. The CAPE might help locate and estimate psychosis risk and can be used as a screening tool in primary care settings/education settings.
