AIMS: Patients with affective and non-affective psychoses show impairments in both the identification and discrimination of facial affect, which can significantly reduce their quality of life. The aim of this commentary is to present the strengths and weaknesses of the available instruments for a more careful evaluation of different stages of emotion processing in clinical and experimental studies on patients with non-affective and affective psychoses. METHODS: We reviewed the existing literature to identify different tests used to assess the ability to recognise (e.g. Ekman 60-Faces Test, Facial Emotion Identification Test and Penn Emotion Recognition Test) and to discriminate emotions (e.g. Face Emotion Discrimination Test and Emotion Differentiation Task). RESULTS: The current literature revealed that few studies combine instruments to differentiate between different levels of emotion processing disorders. The lack of comprehensive instruments that integrate emotion recognition and discrimination assessments prevents a full understanding of patients' conditions. CONCLUSIONS: This commentary underlines the need for a detailed evaluation of emotion processing ability in patients with non-affective and affective psychoses, to characterise the disorder at early phases from the onset of the disease and to design rehabilitation treatments.

BACKGROUND: The incidence of psychotic disorders varies in different geographic areas. As there has been no report from Turkey, this study aimed to provide the treated incidence rate of first-episode psychosis (FEP) in a defined area. METHODS: All individuals, aged 15-64 years, presenting with FEP (ICD-10 F20-29, F30-33) to mental health services in a defined catchment-area in Sinop which is located in the Black Sea region of the northern Turkey were recorded over a 4-year period (2009 to 2012). Incidence rates of psychotic disorders and their 95% confidence intervals (CIs) were estimated. Poisson regression was applied to estimate the differences in incidence rate ratio (IRR) by age, sex, and urbanicity. RESULTS: One hundred and fifteen FEP participants were identified during the 4 years. Crude incidence rates of all psychoses, schizophrenia, other psychotic disorders, and affective psychotic disorders were respectively 38.5 (95% CI 27.1-49.9), 10.7 (95% CI 6.6-14.8), 10.0 (95% CI 5.7-14.3) and 17.7 (95% CI 11.3-24.2) per 100 000 person-years. After age-sex standardisation the rates increased slightly. There were no gender differences in the incidence rates. IRR of any psychotic disorder was highest in the youngest age group (15-24 years) compared to the oldest age group (55-64 years), 7.9 (95% CI 2.8-30.5). In contrast with previous studies, the incidence rate of any psychotic disorder was not significantly increased in urban areas compared with rural areas. CONCLUSIONS: The current study, the first of its kind from Turkey, indicates that the risk of schizophrenia and other psychotic disorders in a lowly urbanised area of Turkey is comparable to those reported in Western European cities.

BACKGROUND: The stressful minority position of transgender persons may result in a high risk of psychosis. Conflicting data suggest that the observed risk depends on setting of recruitment. We assessed the relative risk of non-affective psychotic disorder (NAPD) in a large, representative cohort of transgender persons. METHODS: This cohort was composed using: data on legal sex change from the Dutch population registry and data on dispensing of cross-sex hormones (route 1), and a registry of insurance claims from mental health care including persons with a diagnosis of gender identity disorder (DSM-IV) or gender dysphoria (DSM-5) (route 2). They were matched by sex at birth, calendar year and country of birth to controls from the general population. Transgender persons (N = 5564) and controls (N = 27 820), aged 16-60 years at 1 January 2011, were followed until the first insurance claim for NAPD in 2011-2019. RESULTS: The incidence rate ratio (IRR) of NAPD for transgender persons selected exclusively through route 1 (N = 3859, IRR = 2.00, 95%-CI 1.52-2.63) was increased, but significantly lower than the IRRs for those selected exclusively through route 2 (N = 694, IRR = 22.15, 95%-CI 13.91-35.28) and for those found by both routes (N = 1011, IRR = 5.17, 95%-CI 3.57-7.49; p value for differences in IRR < 0.001). CONCLUSIONS: This study supports the social defeat-hypothesis of NAPD. The results also show the presence of a substantial number of transgender persons with severe psychiatric problems who have not (yet) taken steps to gender-affirmative care.

BACKGROUND: Suicide prevention is a major challenge in the treatment of first-episode affective psychoses. The literature reports that combinations of manic, depressive and paranoid symptoms, which may interact, are associated with an increased risk of suicide. The present study investigated whether interactions between manic, depressive and paranoid symptoms affected suicidality in first-episode affective psychoses. METHODS: We prospectively studied 380 first-episode psychosis patients enrolled in an early intervention programme and diagnosed with affective or non-affective psychoses. We compared intensity and presence of suicidal thoughts and occurrence of suicide attempts over a three-year follow-up period and investigated the impact of interactions between manic, depressive and paranoid symptoms on level of suicidality. RESULTS: At 12 months follow-up, we observed a higher level of suicidal thoughts and higher occurrence of suicide attempts among the affective psychoses patients compared to non-affective psychoses patients. Combined presence of either depressive and paranoid symptoms, or manic and paranoid symptoms, was significantly associated with increased suicidal thoughts. However, the combination of depressive and manic symptoms showed a significant negative association with suicidal thoughts. CONCLUSIONS: This study suggests that paranoid symptoms combined with either manic or depressive symptoms are associated with an increased risk of suicide in first-episode affective psychoses. Detailed assessment of these dimensions is therefore warranted in first-episode affective patients and integrated treatment should be adapted to increased suicidal risk, even if patients do not display full-blown depressive or manic syndromes.

Importance: Less than 10% of research on psychotic disorders has been conducted in settings in the Global South, which refers broadly to the regions of Latin America, Asia, Africa, and Oceania. There is a lack of basic epidemiological data on the distribution of and risks for psychoses that can inform the development of services in many parts of the world. Objective: To compare demographic and clinical profiles of cohorts of cases and rates of untreated psychoses (proxy for incidence) across and within 3 economically and socially diverse settings in the Global South. Two hypotheses were tested: (1) demographic and clinical profiles of cases with an untreated psychotic disorder vary across setting and (2) rates of untreated psychotic disorders vary across and within setting by clinical and demographic group. Design, Setting, and Participants: The International Research Program on Psychotic Disorders in Diverse Settings (INTREPID II) comprises incidence, case-control, and cohort studies of untreated psychoses in catchment areas in 3 countries in the Global South: Kancheepuram District, India; Ibadan, Nigeria; and northern Trinidad. Participants were individuals with an untreated psychotic disorder. This incidence study was conducted from May 1, 2018, to July 31, 2020. In each setting, comprehensive systems were implemented to identify and assess all individuals with an untreated psychosis during a 2-year period. Data were analyzed from January 1 to May 1, 2022. Main Outcomes and Measures: The presence of an untreated psychotic disorder, assessed using the Schedules for Clinical Assessment in Neuropsychiatry, which incorporate the Present State Examination. Results: Identified were a total of 1038 cases, including 64 through leakage studies (Kancheepuram: 268; median [IQR] age, 42 [33-50] years; 154 women [57.5%]; 114 men [42.5%]; Ibadan: 196; median [IQR] age, 34 [26-41] years; 93 women [47.4%]; 103 men [52.6%]; Trinidad: 574; median [IQR] age, 30 [23-40] years; 235 women [40.9%]; 339 men [59.1%]). Marked variations were found across and within settings in the sex, age, and clinical profiles of cases (eg, lower percentage of men, older age at onset, longer duration of psychosis, and lower percentage of affective psychosis in Kancheepuram compared with Ibadan and Trinidad) and in rates of untreated psychosis. Age- and sex-standardized rates of untreated psychoses were approximately 3 times higher in Trinidad (59.1/100â¯000 person-years; 95% CI, 54.2-64.0) compared with Kancheepuram (20.7/100â¯000 person-years; 95% CI, 18.2-23.2) and Ibadan (14.4/100â¯000 person-years; 95% CI, 12.3-16.5). In Trinidad, rates were approximately 2 times higher in the African Trinidadian population (85.4/100â¯000 person-years; 95% CI, 76.0-94.9) compared with the Indian Trinidadian (43.9/100â¯000 person-years; 95% CI, 35.7-52.2) and mixed populations (50.7/100â¯000 person-years; 95% CI, 42.0-59.5). Conclusions and Relevance: This analysis adds to research that suggests that core aspects of psychosis vary by historic, economic, and social context, with far-reaching implications for understanding and treatment of psychoses globally.

PURPOSE: Global understanding of the epidemiological landscape of non-affective psychotic disorders (NAPD) is predominantly based on studies from high-income countries. We sought to systematically review and meta-analyse all incidence studies conducted in low and middle-income countries (LMICs). METHODS: We systematically searched four databases using terms for NAPD, incidence and LMICs. Citations were eligible for inclusion if: published between 1 January 1960 and 31 May 2022; wholly or partially conducted in an LMIC, and; containing data on NAPD incidence in the general adult population. Two independent raters assessed study quality according to previously published criteria. We conducted a narrative synthesis and random-effects meta-analyses where sufficient studies were available (N ≥ 5). RESULTS: We retrieved 11 421 records, of which 23 citations met inclusion criteria from 18 unique studies across 19 settings in 10 LMICs. Median study quality was 4 out of 7 (interquartile range: 3-6). The crude incidence of NAPD varied around 4.2 times, from 10.0 per 100,000 person-years (95% confidence interval [CI] 8.7-11.4) in Brazil to 42.0 (95%CI 32.2-54.8) in India, with marked heterogeneity in methodologies and rates. Our 60-year review highlights the dearth of robust evidence on the incidence of psychotic disorders in LMICs. CONCLUSION: Without reliable, contemporary estimates of this fundamental cornerstone of population health, it is impossible to understand the true burden, distribution or causes of psychotic disorders in over 87% of the world's population. A new, more equitable global mental health evidence base for NAPD is now urgently required.

BACKGROUND: Studies typically highlight area level variation in the incidence of non-affective but not affective psychoses. We compared neighbourhood-level variation for both types of disorder, and the specific effects of neighbourhood urbanicity and ethnic density, using Danish national registry data. METHODS: Population based cohort (2,224,464 people) followed from 1980 to 2013 with neighbourhood exposure measured at age 15 and incidence modelled using multilevel Poisson regression. RESULTS: Neighbourhood variation was similar for both disorders with an adjusted median risk ratio of 1.37 (95% CI 1.34-1.39) for non-affective psychosis and 1.43 (1.38-1.49) for affective psychosis. Associations with neighbourhood urbanicity differed: living in the most compared to the least urban quintile at age 15 was associated with a minimal increase in subsequent affective psychosis, IRR 1.13 (1.01-1.27) but a substantial increase in rates of non-affective psychosis, IRR 1.66 (1.57-1.75). Mixed results were found for neighbourhood ethnic density: for Middle Eastern migrants there was an increased average incidence of both affective, IRR 1.54 (1.19-1.99), and non-affective psychoses, 1.13 (1.04-1.23) associated with each decrease in ethnic density quintile, with a similar pattern for African migrants, but for European migrants ethnic density appeared to be associated with non-affective psychosis only. CONCLUSIONS: While overall variation and the effect of neighbourhood ethnic density were similar for both types of disorder, associations with urbanicity were largely confined to non-affective psychosis. This may reflect differences in aetiological pathways although the mechanism behind these differences remains unknown.

INTRODUCTION: Disorganization is a crucial domain in affective psychoses. However, it has received poor research attention, especially at the illness onset. The aims of this study were: (a) to monitor the longitudinal course of disorganization in young people with first episode affective psychosis (FEAP) across 2 years of follow-up, and (b) to investigate any relevant correlation of disorganized symptoms with psychopathology, functioning and the specific treatment elements of an "Early Intervention in Psychosis" (EIP) protocol along the follow-up period. MATERIALS AND METHODS: Seventy-five FEAP participants (aged 12-35 years) completed the Positive And Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning (GAF). Spearman's rank correlation coefficients were calculated. RESULTS: During the follow-up, disorganized symptoms showed significant enduring positive correlations with PANSS items representing delusional thought content and uncooperativeness, as well as a persistent negative association with the GAF score. Across the 2-year follow-up period, FEAP individuals also had a relevant reduction in disorganization levels. This symptom decrease was specifically related with the combination of antipsychotic medication with the specific psychosocial components of our EIP intervention offered to FEAP patients during the first 12 months of treatment. CONCLUSIONS: Disorganization is relevant in FEAP subjects already at their enrollment in specialized EIP protocols. However, it decreases over time, together with the delivery of specific, combined (person-tailored) EIP interventions.

O ingresso na universidade é marcado por intensas transformações pessoais e pela necessidade de adaptação para um modelo de ensino mais autônomo. Esse cenário pode contribuir para o surgimento de sentimentos de solidão e impactar a qualidade de vida dos universitários. O presente estudo visou investigar as relações entre a solidão e a qualidade de vida em universitários de uma universidade pública do interior de Minas Gerais. Participaram da pesquisa 268 estudantes de graduação selecionados aleatoriamente. Como instrumentos, foram utilizados um questionário sociodemográfico e de hábitos de vida, o Medical Outcomes Study 36 - item Short Form (SF-36), e a Escala Brasileira de Solidão (UCLA-BR). Foram conduzidas análises descritivas e inferenciais (correlação, Kruskal-Wallis e regressão logística). O domínio da qualidade de vida com maior escore foi Capacidade Funcional e Vitalidade foi o menor. Referente à solidão, 60,82% da amostra apresentou nível mínimo. Houve associação significativa entre a solidão e seis domínios da qualidade de vida. A solidão dobrou a chance de pior qualidade de vida nos domínios: aspectos sociais (β = 2,66), limitação emocional (β = 2,18) e saúde mental (β = 2,61). Conclui-se que a solidão impacta negativamente a qualidade de vida dos universitários e que, por isso, são necessárias intervenções para essa população.(AU)
Enrollment in the university is marked by intense personal transformations and the need to adapt to a more autonomous teaching model. This scenario can contribute to the emergence of feelings of loneliness and impact the quality of life of college students. This study aimed to investigate the relationship between loneliness and quality of life in college students at a public university in the interior of the state of Minas Gerais. A total of 268 undergraduate students randomly select took part in the study. The instruments used were a sociodemographic and lifestyle questionnaire, the Medical Outcomes Study 36 - item Short Form (SF-36), and the Brazilian Loneliness Scale (UCLA-BR). Descriptive and inferential analyzes were conducted (correlation, Kruskal-Wallis, and logistic regression). The highest score in the quality of life's domain was Functional Capacity and the lowest was Vitality. Regarding loneliness, 60.82% of the sample had a minimum level. There was a significant association between loneliness and six quality of life domains. Loneliness doubled the chance of worse quality of life for the domains: social aspects (β = 2.66), emotional limitation (β = 2.18), and mental health (β = 2.61). In conclusion, loneliness negatively impacts the quality of life of university students and, therefore, interventions are required for this population.(AU)

The concept of affective psychosis regroups psychotic disorders with mood syndrome. Previous studies provided evidence to support a dichotomy between affective and non-affective psychoses although questions remain regarding the utility and validity of such a category to develop clinical guidelines. The aim of this study is to explore similarities and differences within affective psychoses to question whether strategies would apply to all the diagnoses falling under this umbrella term. Using Bayesian model comparison methods, we explored the homogeneity of the characteristics of first-episode affective patients (N = 77) treated in a specialized 3-year early intervention in psychosis programme. Our analysis revealed affective psychoses display many similarities regarding socio-demographic variables, the course of positive and manic symptoms over three years, and outcome at discharge. Our results did not support the heterogeneous model. However, despite no significant differences in the course of symptoms with the major depressive disorder group, the schizoaffective disorder group displayed a more severe clinical picture at the beginning of the programme and a poorer functional outcome than the two other groups. Absence of clear boundaries and the several similarities within affective psychoses suggest they can usefully be grouped to define treatment strategies that are easily legible by clinicians.

BACKGROUND AND HYPOTHESIS: Evidence suggests that childhood maltreatment (ie, childhood abuse and childhood neglect) affects educational attainment and cognition. However, the association between childhood maltreatment and Intelligence Quotient (IQ) seems stronger among controls compared to people with psychosis. We hypothesised that: the association between childhood maltreatment and poor cognition would be stronger among community controls than among people with first-episode of psychosis (FEP); compared to abuse, neglect would show stronger associations with educational attainment and cognition; the association between childhood maltreatment and IQ would be partially accounted for by other risk factors; and the association between childhood maltreatment, educational attainment, and IQ would be stronger among patients with affective psychoses compared to those with nonaffective psychoses. STUDY DESIGN: 829 patients with FEP and 1283 community controls from 16 EU-GEI sites were assessed for child maltreatment, education attainment, and IQ. STUDY RESULTS: In both the FEP and control group, childhood maltreatment was associated with lower educational attainment. The association between childhood maltreatment and lower IQ was robust to adjustment for confounders only among controls. Whereas childhood neglect was consistently associated with lower attainment and IQ in both groups, childhood abuse was associated with IQ only in controls. Among both patients with affective and nonaffective psychoses, negative associations between childhood maltreatment and educational attainment were observed, but the crude association with IQ was only evident in affective psychoses. CONCLUSIONS: Our findings underscore the role of childhood maltreatment in shaping academic outcomes and cognition of people with FEP as well as controls.

BACKGROUND: Cognitive reserve (CR) is a protective factor against cognitive and functional impairment in first-episode psychosis (FEP). The aim of this study was to evaluate the differences in clinical presentation according to the use of cannabis (cannabis users vs non-users) among patients presenting a FEP (non-affective vs affective psychosis), to investigate the impact of CR and cannabis use on several outcomes and to explore the potentially mediatory role played by CR in the relationship between cognitive domains or clinical status and functionality, depending on the use of cannabis. METHODS: Linear regression analysis models were carried out to assess the predictive value of CR on clinical, functional and cognitive variables at baseline and at two-year follow-up. The mediation analyzes were performed according to the principles of Baron and Kenny. RESULTS: CR was associated with better cognitive performance, regardless of cannabis consumption or diagnosis. In both diagnoses, CR was associated with better clinical and functional outcomes in those patients who did not use cannabis. In terms of mediation procedure, CR mediates the relationship between some cognitive domains and functioning at follow-up only in patients without cannabis use. LIMITATIONS: The small sample size of the affective group. CONCLUSIONS: CR plays a differential role in the outcome of psychoses according to whether patients are cannabis users or not. Both in affective and non-affective groups CR exerted a greater effect in patients without cannabis use. Our results suggest that the deleterious effect of cannabis use on functioning in FEP surpasses the protective effect of CR.

Early-onset psychosis disorders are serious mental disorders arising before the age of 18 years. Here, we investigate the largest neuroimaging dataset, to date, of patients with early-onset psychosis and healthy controls for differences in intracranial and subcortical brain volumes. The sample included 263 patients with early-onset psychosis (mean age: 16.4 ± 1.4 years, mean illness duration: 1.5 ± 1.4 years, 39.2% female) and 359 healthy controls (mean age: 15.9 ± 1.7 years, 45.4% female) with magnetic resonance imaging data, pooled from 11 clinical cohorts. Patients were diagnosed with early-onset schizophrenia (n = 183), affective psychosis (n = 39), or other psychotic disorders (n = 41). We used linear mixed-effects models to investigate differences in intracranial and subcortical volumes across the patient sample, diagnostic subgroup and antipsychotic medication, relative to controls. We observed significantly lower intracranial (Cohen's d = -0.39) and hippocampal (d = -0.25) volumes, and higher caudate (d = 0.25) and pallidum (d = 0.24) volumes in patients relative to controls. Intracranial volume was lower in both early-onset schizophrenia (d = -0.34) and affective psychosis (d = -0.42), and early-onset schizophrenia showed lower hippocampal (d = -0.24) and higher pallidum (d = 0.29) volumes. Patients who were currently treated with antipsychotic medication (n = 193) had significantly lower intracranial volume (d = -0.42). The findings demonstrate a similar pattern of brain alterations in early-onset psychosis as previously reported in adult psychosis, but with notably low intracranial volume. The low intracranial volume suggests disrupted neurodevelopment in adolescent early-onset psychosis.

BACKGROUND: Evidence suggests the incidence of non-affective psychotic disorders (NAPDs) varies across persons and places, but data from the Global South is scarce. We aimed to estimate the treated incidence of NAPD in Chile, and variance by person, place and time. METHODS: We used national register data from Chile including all people, 10-65 years, with the first episode of NAPD (International Classification of Diseases, Tenth Revision: F20-F29) between 1 January 2005 and 29 August 2018. Denominators were estimated from Chilean National Census data. Our main outcome was treated incidence of NAPD and age group, sex, calendar year and regional-level population density, multidimensional poverty and latitude were exposures of interest. RESULTS: We identified 32 358 NAPD cases [12 136 (39.5%) women; median age-at-first-contact: 24 years (interquartile range 18-39 years)] during 171.1 million person-years [crude incidence: 18.9 per 100 000 person-years; 95% confidence interval (CI) 18.7-19.1]. Multilevel Poisson regression identified a strong age-sex interaction in incidence, with rates peaking in men (57.6 per 100 000 person-years; 95% CI 56.0-59.2) and women (29.5 per 100 000 person-years; 95% CI 28.4-30.7) between 15 and 19 years old. Rates also decreased (non-linearly) over time for women, but not men. We observed a non-linear association with multidimensional poverty and latitude, with the highest rates in the poorest regions and those immediately south of Santiago; no association with regional population density was observed. CONCLUSION: Our findings inform the aetiology of NAPDs, replicating typical associations with age, sex and multidimensional poverty in a Global South context. The absence of association with population density suggests this risk may be context-dependent.

OBJECTIVE: While there is considerable current emphasis on youth and early psychosis, relatively little is known about the lives of people who live with psychotic disorders into middle age and beyond. We investigated social functioning, physical health status, substance use and psychiatric symptom profile in people with psychotic disorders aged between 50 and 65 years. METHODS: Data were collected as part of the Survey of High Impact Psychosis, a population-based survey of Australians aged 18-65 years with a psychotic disorder. We compared those aged 50-65 years (N = 347) with those aged 18-49 years (N = 1478) across a range of measures. RESULTS: The older group contained more women and more people with affective psychoses compared to the younger group. They were also more likely to have had a later onset and a chronic course of illness. The older group were more likely to have negative symptoms but less likely to exhibit positive symptoms; they also had lower current cognition, compared to the younger group. Compared to the younger group, the older group were more likely to be divorced/separated, to be living alone and to be unemployed. They had substantially lower lifetime use of alcohol and illicit substances, but rates of obesity, metabolic syndrome and diabetes mellitus were higher. CONCLUSION: Our findings suggest that the characteristics of people with psychosis change significantly as they progress into the middle age and beyond. A better understanding of these differences is important in informing targeted treatment strategies for older people living with psychosis.

BACKGROUND: Immune dysfunction has been implicated in the pathogenesis of schizophrenia and other nonaffective psychosis (SCZ), bipolar spectrum disorder (BIP) and major depressive disorder (MDD). The cytokines B cell-activating factor (BAFF) and A proliferation-inducing ligand (APRIL) belong to the tumor necrosis factor (TNF) super family and are essential in orchestrating immune responses. Abnormal levels of BAFF and APRIL have been found in autoimmune diseases with CNS affection. METHODS: We investigated if plasma levels of BAFF and APRIL differed between patients with SCZ, BIP, and MDD with psychotic symptoms (n = 2009) and healthy control subjects (HC, n = 1212), and tested for associations with psychotic symptom load, controlling for sociodemographic status, antipsychotic and other psychotropic medication, smoking, body-mass-index, and high sensitivity CRP. RESULTS: Plasma APRIL level was significantly lower across all patient groups compared to HC (P < .001; Cohen's d = 0.33), and in SCZ compared to HC (P < .001; d = 0.28) and in BIP compared to HC (P < .001; d = 0.37). Lower plasma APRIL was associated with higher psychotic symptom load with nominal significance (P = .017), but not with any other clinical characteristics. Plasma BAFF was not significantly different across patient groups vs HC, but significantly higher in BIP compared to HC (P = .040; d = 0.12) and SCZ (P = .027; d = 0.10). CONCLUSIONS: These results show aberrant levels of BAFF and APRIL and association with psychotic symptoms in patients with SCZ and BIP. This suggest that dysregulation of the TNF system, mediated by BAFF and APRIL, is involved in the pathophysiology of psychotic disorders.

This paper reviews the career of Robert Kendell with emphasis on his contribution to diagnosis in psychiatry. His studies on the classification of depression showed that symptoms were distributed on a continuum and that division of depression into sub-types was not justified. Similarly he showed there was no clear-cut distinction between symptoms of schizophrenia and affective psychoses. He examined Scadding's definition of disease as it applied to psychiatry and questioned whether some conditions such as neuroses and personality disorders would qualify as illnesses. He concluded that available evidence supported a dimensional rather than a categorical approach to diagnosis.

ABSTRACT: Perceptions of patient's auditory verbal hallucinations (AVHs), commonly termed voices, have important impacts on their everyday lives. Despite research emphasizing the consequences of malevolent voices, preliminary results suggest that beliefs about voices may not be mutually exclusive. As such, we aimed to characterize the heterogeneity of beliefs about AVHs and describe their clinical correlates. We recruited 78 patients referred to a Voices group therapy for refractory and distressing voices. Based on the Revised Beliefs About Voices Questionnaire, clustering analysis yielded four subgroups of patients with distinct pattern of beliefs about AVHs. These subgroups differed significantly in terms of affective disturbances, engagement, and resistance to their voices. Furthermore, no significant changes in beliefs about voices were observed after 6 weeks. Results of the current study suggest that the heterogeneity regarding the beliefs about AVHs should be targeted in treatment to reduce their associated negative outcomes.
