Abstract
One of the most used self-administered instruments to assess persecutory delusions is the Persecutory Ideation Questionnaire (PIQ). Individual differences in PIQ scores are important because they predict the severity of symptoms associated with psychosis-related disorders. The current research demonstrates that PIQ is associated with two new outcomes: Satisfaction with life (Studies 1 and 2) and therapy length needed for hospital discharge (Study 2). Most relevant, we introduce meta-cognitive confidence in one's scale responses as a construct capable of improving the predictive validity of the PIQ. Across two studies, participants from the general population (Study 1) and from a clinical sample (Study 2) completed the PIQ and then reported the confidence in their responses. As expected, the PIQ was associated with satisfaction with life in both cases and duration of therapy required to receive hospital discharge for the clinical sample. Most importantly, confidence further moderated the extent to which the PIQ scores were linked with both outcomes, with greater consistency between the PIQ and the dependent measures obtained for those with higher confidence. Therefore, asking a single item about the confidence associated with responses to the PIQ enhances the association of PIQ scores and relevant consequences across domains.

Schizophr Res 2024; 269:116-119.

Abstract
The jumping to conclusions (JTC) bias has been linked to the formation and maintenance of delusions across the psychosis spectrum. However, it remains unclear whether this bias reflects a primary cognitive deviation or is secondary to other cognitive processes. To this end, we investigated the relationship between JTC, risk-taking, impulsivity, and sensation seeking in individuals with psychotic-like experiences (PLEs) and controls. A large online community sample (N = 1151) completed the Fish Task as a measure for the JTC bias, as well as the Balloon Analogue Risk Task (BART) and the Brief Risk-Taking Propensity Scale (R-1) as measures of the propensity to take risks. Measures assessing impulsivity (Impulsive Behavior Scale-8, I-8), sensation seeking (Brief Sensation Seeking Scale, BSSS-4), and verbal intelligence (12-item Wordsum test) were also administered. We dichotomized the sample into extreme groups based on the positive subscale of the Community Assessment of Psychotic Experiences (CAPE). The present study confirms the existence of a JTC bias in psychosis-prone individuals. Of note, PLE-high individuals self-reported higher risk-taking propensity in the R-1 while at the same time displaying higher objective risk aversion in the BART relative to controls, speaking for a dissociation of subjective versus objective risk-taking behavior. PLE-high individuals showed deviances in other psychological traits (impulsivity, sensation seeking), but these were not associated with hasty decision-making as measured by JTC or risk-taking propensity. The results speak against impulsivity, sensation seeking, or verbal intelligence as driving mechanisms of JTC and risky decision-making.

Abstract
Psychedelic agents, such as LSD and psilocybin, induce marked alterations in consciousness via activation of the 5-HT2A receptor (5-HT2ARs). We hypothesize that psychedelics enforce a state of synthetic surprise through the biased activation of the 5-HTRs system. This idea is informed by recent insights into the role of 5-HT in signaling surprise. The effects on consciousness, explained by the cognitive penetrability of perception, can be described within the predictive coding framework where surprise corresponds to prediction error, the mismatch between predictions and actual sensory input. Crucially, the precision afforded to the prediction error determines its effect on priors, enabling a dynamic interaction between top-down expectations and incoming sensory data. By integrating recent findings on predictive coding circuitry and 5-HT2ARs transcriptomic data, we propose a biological implementation with emphasis on the role of inhibitory interneurons. Implications arise for the clinical use of psychedelics, which may rely primarily on their inherent capacity to induce surprise in order to disrupt maladaptive patterns.

Abstract
BACKGROUND AND HYPOTHESIS Childhood adversity is associated with a myriad of psychiatric symptoms, including psychotic experiences (PEs), and with multiple psychological processes that may all mediate these associations. STUDY DESIGN Using a network approach, the present study examined the complex interactions between childhood adversity, PEs, other psychiatric symptoms, and multiple psychological mediators (ie, activity-related and social stress, negative affect, loneliness, threat anticipation, maladaptive cognitive emotion regulation, attachment insecurity) in a general population, adolescent sample (n = 865, age 12-20, 67% female). STUDY RESULTS Centrality analyses revealed a pivotal role of depression, anxiety, negative affect, and loneliness within the network and a bridging role of threat anticipation between childhood adversity and maladaptive cognitive emotion regulation. By constructing shortest path networks, we found multiple existing paths between different categories of childhood adversity and PEs, with symptoms of general psychopathology (ie, anxiety, hostility, and somatization) as the main connective component. Sensitivity analyses confirmed the robustness and stability of the networks. Longitudinal analysis in a subsample with Wave 2 data (n = 161) further found that variables with higher centrality (ie, depression, negative affect, and loneliness) better predicted follow-up PEs. CONCLUSIONS Pathways linking childhood adversity to PEs are complex, with multifaceted psychological and symptom-symptom interactions. They underscore the transdiagnostic, heterotypic nature of mental ill-health in young people experiencing PEs, in agreement with current clinical recommendations.

Abstract
Childhood adversity is associated with psychopathology. First evidence in adults suggests that threat anticipation, i.e., an enhanced anticipation of unpleasant events creating an enduring sense of threat, may be a putative mechanism linking childhood adversity to psychopathology. This study aimed to test the indirect effect of childhood adversity on psychopathology via threat anticipation in a large community sample of adolescents. We measured childhood trauma and bullying victimization (as indicators of childhood adversity), threat anticipation, general psychopathology and prodromal psychotic symptoms in adolescents aged 12-16 years (full sample size N = 1682; minimum sample size in the complete case sample N = 449) in wave I of the SIGMA study. We found strong evidence that childhood adversity (e.g. childhood trauma, adj. β (aβ) = 0.54, p < .001) and threat anticipation (e.g. aβ = 0.36, p < .001) were associated with general psychopathology and prodromal psychotic symptoms. Moreover, there was evidence that the association between childhood adversity, general psychopathology and prodromal psychotic symptoms is mediated via pathways through threat anticipation (e.g. childhood trauma, aβindirect effect = 0.13, p < .001). Threat anticipation may be a potential mechanism linking childhood adversity and psychopathology in adolescents.

Abstract
BACKGROUND Empirical evidence suggests that people use cannabis to ameliorate anxiety and depressive symptoms, yet cannabis also acutely worsens psychosis and affective symptoms. However, the temporal relationship between cannabis use, anxiety and depressive symptoms and psychotic experiences (PE) in longitudinal studies is unclear. This may be informed by examination of mutually mediating roles of cannabis, anxiety and depressive symptoms in the emergence of PE. METHODS Data were derived from the second longitudinal Netherlands Mental Health Survey and Incidence Study. Mediation analysis was performed to examine the relationship between cannabis use, anxiety/depressive symptoms and PE, using KHB logit in STATA while adjusting for age, sex and education status. RESULTS Cannabis use was found to mediate the relationship between preceding anxiety, depressive symptoms and later PE incidence, but the indirect contribution of cannabis use was small (for anxiety: % of total effect attributable to cannabis use = 1.00%; for depression: % of total effect attributable to cannabis use = 1.4%). Interestingly, anxiety and depressive symptoms were found to mediate the relationship between preceding cannabis use and later PE incidence to a greater degree (% of total effect attributable to anxiety = 17%; % of total effect attributable to depression = 37%). CONCLUSION This first longitudinal cohort study examining the mediational relationship between cannabis use, anxiety/depressive symptoms and PE, shows that there is a bidirectional relationship between cannabis use, anxiety/depressive symptoms and PE. However, the contribution of anxiety/depressive symptoms as a mediator was greater than that of cannabis.

Abstract
AIM Thinking biases are posited to be involved in the genesis and maintenance of delusions. Persecutory delusions are one of the most commonly occurring delusional subtypes and cause substantial distress and disability to the individuals experiencing them. Their clinical relevance confers a rationale for investigating them. Particularly, this review aims to elucidate which cognitive biases are involved in their development and persistence. METHODS MEDLINE, Embase, PsycINFO and Global Health were searched from the year 2000 to June 2020. A formal narrative synthesis was employed to report the findings and a quality assessment of included studies was conducted. RESULTS Twenty five studies were included. Overall, 18 thinking biases were identified. Hostility and trustworthiness judgement biases appeared to be specific to persecutory delusions while jumping to conclusions, self-serving attributional biases and belief inflexibility were proposed to be more closely related to other delusional subtypes. While the majority of the biases identified were suggested to be involved in delusion maintenance, hostility biases, need for closure and personalizing attributional biases were believed to also have aetiological influences. CONCLUSIONS These findings show that some cognitive biases are specific to paranoid psychosis and appear to be involved in the formation and/or persistence of persecutory delusions.

Abstract
BACKGROUND There is evidence that environmental and genetic risk factors for schizophrenia spectrum disorders are transdiagnostic and mediated in part through a generic pathway of affective dysregulation. METHODS We analysed to what degree the impact of schizophrenia polygenic risk (PRS-SZ) and childhood adversity (CA) on psychosis outcomes was contingent on co-presence of affective dysregulation, defined as significant depressive symptoms, in (i) NEMESIS-2 (n = 6646), a representative general population sample, interviewed four times over nine years and (ii) EUGEI (n = 4068) a sample of patients with schizophrenia spectrum disorder, the siblings of these patients and controls. RESULTS The impact of PRS-SZ on psychosis showed significant dependence on co-presence of affective dysregulation in NEMESIS-2 [relative excess risk due to interaction (RERI): 1.01, p = 0.037] and in EUGEI (RERI = 3.39, p = 0.048). This was particularly evident for delusional ideation (NEMESIS-2: RERI = 1.74, p = 0.003; EUGEI: RERI = 4.16, p = 0.019) and not for hallucinatory experiences (NEMESIS-2: RERI = 0.65, p = 0.284; EUGEI: -0.37, p = 0.547). A similar and stronger pattern of results was evident for CA (RERI delusions and hallucinations: NEMESIS-2: 3.02, p < 0.001; EUGEI: 6.44, p < 0.001; RERI delusional ideation: NEMESIS-2: 3.79, p < 0.001; EUGEI: 5.43, p = 0.001; RERI hallucinatory experiences: NEMESIS-2: 2.46, p < 0.001; EUGEI: 0.54, p = 0.465). CONCLUSIONS The results, and internal replication, suggest that the effects of known genetic and non-genetic risk factors for psychosis are mediated in part through an affective pathway, from which early states of delusional meaning may arise.

Crowter L, Banerjee R, Berry C, Fowler D. Schematic beliefs, negative affect and paranoia in at-risk youth. BRITISH JOURNAL OF CLINICAL PSYCHOLOGY 2022; 61:1038-1051.

Abstract
OBJECTIVES Attenuated symptoms of psychosis are a core feature of At-Risk Mental States. However, subthreshold levels of paranoia are also common among nonpsychosis populations. At present, little is known about whether the processes underpinning the experience of paranoid ideation in high-risk youth differ as a consequence of meeting At-Risk Mental States (ARMS) for psychosis criteria. METHODS This study utilized path analysis techniques to examine the relationships between schematic beliefs, negative affect and the experience of paranoia for two groups: a group meeting criteria for ARMS (n = 133) and a group presenting with emerging complex mental health difficulties who did not meet the criteria for ARMS (n = 137). RESULTS While the ARMS group displayed significantly greater maladaptive schematic beliefs and more severe symptomatology, the associations between schematic beliefs, symptoms of negative affect and paranoia did not differ as a consequence of ARMS status. CONCLUSIONS While meeting the ARMS criteria is associated with experiencing more maladaptive cognitions and more negative symptomatology among at-risk youth, the associations between these cognitive beliefs and symptoms may be similar for youth who do not meet ARMS. These findings have implications for broadening the scope of at-risk/high-risk and for developing effective interventions for young people presenting with emerging difficulties.

Abstract
BACKGROUND Obsessive-compulsive disorder (OCD) is a common mental disorder that varies greatly in manifestation and causes much distress to individuals. We describe a case in which a Chinese woman with OCD became delusional after childbirth, and discuss the possible phenomenological and psychological alterations.
CASE SUMMARY A 27-year-old woman presented to the Psychiatry Department of our hospital with obsessions and compulsions. After taking medication, her symptoms were alleviated. Three years later, during her pregnancy, the obsessions returned and even progressed into paranoid delusions after childbirth. After multiple adjustments of treatment along with several fluctuations, she finally achieved remission and gained reasonable insight.
CONCLUSION This case suggests that the patient with OCD appeared to move along a continuum of beliefs, and highlights the importance of effective intervention during pregnancy, which would exert a significant impact on postpartum exacerbation outcomes.

Effects of a Novel, Transdiagnostic, Hybrid Ecological Momentary Intervention for Improving Resilience in Youth (EMIcompass): Protocol for an Exploratory Randomized Controlled Trial. JMIR Res Protoc 2021; 10:e27462.

Abstract
BACKGROUND Most mental disorders first emerge in youth and, in their early stages, surface as subthreshold expressions of symptoms comprising a transdiagnostic phenotype of psychosis, mania, depression, and anxiety. Elevated stress reactivity is one of the most widely studied mechanisms underlying psychotic and affective mental health problems. Thus, targeting stress reactivity in youth is a promising indicated and translational preventive strategy for adverse mental health outcomes that could develop later in life and for improving resilience. Compassion-focused interventions offer a wide range of innovative therapeutic techniques that are particularly amenable to being implemented as ecological momentary interventions (EMIs), a specific type of mobile health intervention, to enable youth to access interventions in a given moment and context in daily life. This approach may bridge the current gap in youth mental health care. OBJECTIVE This study aims to investigate the clinical feasibility, candidate underlying mechanisms, and initial signals of the efficacy of a novel, transdiagnostic, hybrid EMI for improving resilience to stress in youth-EMIcompass. METHODS In an exploratory randomized controlled trial, youth aged between 14 and 25 years with current distress, a broad Clinical High At-Risk Mental State, or the first episode of a severe mental disorder will be randomly allocated to the EMIcompass intervention (ie, EMI plus face-to-face training sessions) in addition to treatment as usual or a control condition of treatment as usual only. Primary (stress reactivity) and secondary candidate mechanisms (resilience, interpersonal sensitivity, threat anticipation, negative affective appraisals, and momentary physiological markers of stress reactivity), as well as primary (psychological distress) and secondary outcomes (primary psychiatric symptoms and general psychopathology), will be assessed at baseline, postintervention, and at the 4-week follow-up. RESULTS The first enrollment was in August 2019, and as of May 2021, enrollment and randomization was completed (N=92). We expect data collection to be completed by August 2021. CONCLUSIONS This study is the first to establish feasibility, evidence on underlying mechanisms, and preliminary signals of the efficacy of a compassion-focused EMI in youth. If successful, a confirmatory randomized controlled trial will be warranted. Overall, our approach has the potential to significantly advance preventive interventions in youth mental health provision.

Dopamine, Serotonin, and Structure/Function Brain Defects as Biological Bases for Treatment Response in Delusional Disorder: A Systematic Review of Cases and Cohort Studies. Behav Sci (Basel) 2021; 11:bs11100141.

Abstract
Although blockade of dopamine receptors D2 and D3 appears to be the main mechanism of antipsychotic action, treatment response variability calls for an examination of other biological systems. Our aim is to systematically review reports of treatment response in delusional disorder (DD) in order to help determine its biological bases. Computerized searches of ClinicalTrials.gov, PubMed, and Scopus databases (from 1999 to September 2021) were systematically reviewed, in keeping with PRISMA directives. We used the search terms: (treat * OR therap * AND (delusional disorder)). We included all studies that explored the biological mechanisms of treatment response in DD, as diagnosed by ICD or DSM criteria. A total of 4344 records were initially retrieved, from which 14 papers were included: case reports, case series, and cohort studies. Findings point to (1) dopaminergic dysfunction (based on biochemical and genetic studies), (2) serotonergic dysfunction (based on partial agonism/antagonism of drugs), and (3) brain structure/function impairment, especially in the temporal and parietal lobes, as crucial factors in treatment response. Further studies with higher levels of evidence are needed to help clinicians determine treatment.

Abstract
Negative self and negative other schema have been implicated in the development of paranoia. The current study provides a meta-analysis, narrative review and quality appraisal of quantitative studies investigating the relationship between negative self and negative other schema and paranoia across the paranoia continuum. A systematic search identified 43 eligible studies; 25 were included in the meta-analysis. Meta-analytic findings demonstrated a medium to large relationship between paranoia and negative self-schema (r = 0.46, 95% CI 0.39 to 0.53) and negative other schema (r = 0.48, 95% CI 0.38 to 0.56). The magnitude of associations was similar across people with and without psychosis. Findings demonstrated that associations between negative self-schema and paranoia were not always statistically significant when controlling for confounding variables, particularly depression. The association between negative other schema and paranoia tended to remain significant when controlling for confounding variables. Findings also demonstrated that negative schema may mediate relationships between adverse experiences in childhood and paranoia. Overall, findings support theoretical proposals that both negative self and negative other schema are associated with paranoia. Longitudinal studies are required to confirm the direction of effects. Findings provide support for incorporating and targeting negative self and negative other schema in psychological formulations and therapeutic work.

Abstract
BACKGROUND Digital interventions offer new avenues for low-threshold prevention and treatment in young people. Ecological momentary interventions (EMIs) represent a powerful approach that allows for adaptive, real-time, and real-world delivery of intervention components in daily life by real-time processing of ecological momentary assessment (EMA) data. Compassion-focused interventions (CFIs) may be particularly amenable to translation into an EMI to strengthen emotional resilience and modify putative risk mechanisms, such as stress sensitivity, in the daily lives of young help-seeking individuals. OBJECTIVE This study aims to investigate the feasibility, safety, and initial therapeutic effects of a novel, accessible, transdiagnostic, ecological momentary CFI for improving emotional resilience to stress (EMIcompass). METHODS In this uncontrolled pilot study, help-seeking youth with psychotic, depressive, or anxiety symptoms were offered the EMIcompass intervention in addition to treatment as usual. The EMIcompass intervention consisted of a 3-week EMI (including enhancing, consolidating, and EMA-informed interactive tasks) administered through a mobile health app and three face-to-face sessions with a trained psychologist intended to provide guidance and training on the CFI exercises presented in the app (ie, training session, follow-up booster session, and review session). RESULTS In total, 10 individuals (mean age 20.3 years, SD 3.8; range 14-25) were included in the study. Most (8/10, 80%) participants were satisfied and reported a low burden of app usage. No adverse events were observed. In approximately one-third of all EMAs, individuals scored high on stress, negative affect, or threat anticipation during the intervention period, resulting in real-time, interactive delivery of the CFI intervention components in addition to weekly enhancing and daily consolidating tasks. Although the findings should be interpreted with caution because of the small sample size, reduced stress sensitivity, momentary negative affect, and psychotic experiences, along with increased positive affect, were found at postintervention and the 4-week follow-up. Furthermore, reductions in psychotic, anxiety, and depressive symptoms were found (r=0.30-0.65). CONCLUSIONS Our findings provide evidence on the feasibility and safety of the EMIcompass intervention for help-seeking youth and lend initial support to beneficial effects on stress sensitivity and mental health outcomes. An exploratory randomized controlled trial is warranted to establish the feasibility and preliminary evidence of its efficacy.

The relationship between conventional clinical assessments and momentary assessments of symptoms and functioning in schizophrenia spectrum disorders: A systematic review. Schizophr Res 2021; 232:11-27. [PMID: 34004382 DOI: 10.1016/j.schres.2021.04.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 04/09/2021] [Accepted: 04/25/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Symptoms and functioning are critical dimensions in those with schizophrenia and are typically measured using validated conventional clinical assessments. Researchers and clinicians have begun to use real-time digital methods, such as ecological momentary assessment (EMA), to assess symptoms and functioning in the moment and outside of traditional hospital and laboratory settings, which may yield more naturalistic data. Although digital methods have advantages, it is unclear whether these momentary assessments capture core aspects of symptoms and functioning. OBJECTIVE This systematic literature review aimed to evaluate the association between conventional clinical and momentary-based assessments of functioning and symptoms in individuals with schizophrenia. METHODS Studies were included if they met the following criteria: (1) written or translated into English; (2) peer-reviewed; (3) included primary quantitative data; (4) 60% of the clinical sample included persons with schizophrenia spectrum disorders; (5) included a clinical assessment of functioning and/or symptoms; (6) included active momentary assessment and/or passive data; and (7) assessed the relationship between the momentary and conventional clinical assessments. RESULTS A total of 49 studies (87 analyses) were included. Conventional clinical assessments of functioning and positive, negative, and depressive symptoms were related to momentary assessments of these symptom domains. Passive data was beneficial for assessing negative symptoms, but research is warranted for other domains. CONCLUSIONS The reviewed studies highlight the utility of EMA methodologies to collect detailed data on symptoms and functioning. Such data is being used to develop more sophisticated models of schizophrenia to enhance our understanding of important mechanisms and develop targeted interventions.

Abstract
AIMS Childhood trauma is associated with an elevated risk for psychosis, but the psychological mechanisms involved remain largely unclear. This study aimed to investigate emotional and psychotic stress reactivity in daily life as a putative mechanism linking childhood trauma and clinical outcomes in individuals at ultra-high-risk (UHR) for psychosis. METHODS Experience sampling methodology was used to measure momentary stress, affect and psychotic experiences in the daily life of N = 79 UHR individuals in the EU-GEI High Risk Study. The Childhood Trauma Questionnaire was used to assess self-reported childhood trauma. Clinical outcomes were assessed at baseline, 1- and 2-year follow-up. RESULTS The association of stress with positive (β = -0.14, p = 0.010) and negative affect (β = 0.11, p = 0.020) was modified by transition status such that stress reactivity was greater in individuals who transitioned to psychosis. Moreover, the association of stress with negative affect (β = 0.06, p = 0.019) and psychotic experiences (β = 0.05, p = 0.037) was greater in individuals exposed to high v. low levels of childhood trauma. We also found evidence that decreased positive affect in response to stress was associated with reduced functioning at 1-year follow-up (B = 6.29, p = 0.034). In addition, there was evidence that the association of childhood trauma with poor functional outcomes was mediated by stress reactivity (e.g. indirect effect: B = -2.13, p = 0.026), but no evidence that stress reactivity mediated the association between childhood trauma and transition (e.g. indirect effect: B = 0.14, p = 0.506). CONCLUSIONS Emotional and psychotic stress reactivity may be potential mechanisms linking childhood trauma with clinical outcomes in UHR individuals.

Abstract
OBJECTIVE Individuals with psychosis self-report difficulties in understanding, relating, and responding to emotions as treatment priorities, yet we lack comprehensive, reliable, and valid assessments for routine clinical use. METHODS The psychometric properties of a brief version of the Difficulties in Emotion Regulation Scale-16 (DERS-16) were examined using anonymized data from a sample of 150 outpatients with psychosis. RESULTS Confirmatory factor analysis supported the five-factor structure of the DERS-16. The model fit was further improved by omitting two items. Measurement invariance was shown with respect to age and gender. The DERS-16 demonstrated good internal consistency, well comparable to the original DERS. Evidence toward convergent validity is also presented. CONCLUSION Findings suggest that the DERS-16 is a reliable and valid measure of self-reported emotion regulation difficulties in individuals with psychosis. Further research on the clinical utility of the DERS-16 is needed, including examination of its test-retest reliability and predictive validity in response to targeted interventions.

Although Karl Jaspers' concept of the primary delusion (PD) is a key hypothesis in descriptive phenomenology concerning the primordial experience of delusion, to our knowledge it has not been verified in empirical studies of patients with psychosis, and the relationship between PDs and fully developed delusions remains unclear. METHODS The subjects were 108 psychiatric patients diagnosed with DSM-IV schizophrenia or schizoaffective disorder who had persisting delusions. This investigation used a newly devised semi-structured interview, the Delusion and its Origin Assessment Interview (DOAI), and the Positive and Negative Syndrome Scale. PDs enquired about in the DOAI were delusional perception, delusional memory, delusional mood, and delusional intuition. Associations of PDs with delusion themes and delusion features extracted from DOAI items by factor analysis were examined using correlational and MANCOVA regression analyses. Reliability studies of the DOAI were also conducted. RESULTS The reliability and correlation analyses suggested robust psychometric properties of the DOAI. The percentages of subjects reporting PD phenomena as delusion origins and currently present were 93% and 84%, respectively. MANCOVA revealed several significant associations, including between delusional perception and delusional mood and persecutory themes, between delusional intuition and grandiose delusions, and between delusional perception and intuition and systematization of delusions. DISCUSSION This study demonstrates that PDs can be considered as principal origins of delusions by subjects with psychosis, and have meaningful connections with the characteristics of their fully developed delusions. The associations between PDs and delusion characteristics can be interpreted in terms of progression processes of delusions, which are seen as intensification and generalization of cognitive and affective pathologies in PDs. The findings are also consistent with the neurobiological hypothesis that aberrant salience attribution to stimuli, as in PDs, is the primary phenomenon caused by abnormal dopamine system regulation. Further studies are needed to clarify delusion progression processes relating to PDs and to substantiate their clinical meanings.

Effects of traumatic life events, cognitive biases and variation in dopaminergic genes on psychosis proneness. Early Interv Psychiatry 2021; 15:248-255.

Abstract
AIMS Recent studies have provided evidence that interactions between variation in dopaminergic genes and stressful experiences might impact risk of psychosis. However, it remains unknown whether these interactions impact the development of subclinical symptoms, including psychotic-like experiences (PLEs). In this study, we aimed to test the effects of interactions between variation in dopaminergic genes and traumatic life events (TLEs) on a severity of PLEs. METHODS We assessed TLEs, cognitive biases, PLEs as well as the catechol-O-methyltransferase (COMT) rs4680 and the dopamine D2 receptor (DRD2) rs6277 gene polymorphisms in 445 university students at three urban areas. RESULTS There was a significant effect of the interaction between the COMT rs4680 and a history of any type of TLEs on a severity of PLEs. Among the COMT rs4680 Met allele carriers, a severity of PLEs was higher in individuals with a history of any type of TLEs. Further stratification of the sample revealed that this effect appears only in the group of participants with a high level of cognitive biases. The DRD2 rs6277 C allele was independently associated with a higher level of PLEs. CONCLUSIONS Our results indicate that decreased dopamine catabolism related to the COMT gene polymorphism might increase psychosis proneness in individuals with a history of TLEs and high levels of cognitive biases. Variation in the DRD2 gene might exert independent effects on psychosis proneness. These findings imply that there are various levels of complexity in the models of interactions between genetic and environmental factors explaining the mechanisms underlying psychosis proneness.

Abstract
Abstract
Treatment recommendations for mental health are often founded on diagnosis-specific models; however, there are high rates of co-morbidity of mental health presentations and growing recognition of the presence of ‘transdiagnostic processes’ (cognitive, emotional or behavioural features) seen across a range of mental health presentations. This model proposes a novel conceptualisation of how transdiagnostic behaviours may maintain co-morbid mental health presentations by acting as a trigger event for the cognitive biases specific to each presentation. Drawing on existing evidence, psychological theory and the author’s clinical experience, the model organises complex presentations in a theory-driven yet accessible manner for use in clinical practice. The model offers both theoretical and clinical implications for the treatment of mental health presentations using cognitive behavioural approaches, positing that transdiagnostic behaviours be the primary treatment target in co-morbid presentations.
Key learning aims

To understand the strengths and limitations of existing transdiagnostic CBT formulation models.
(2)
To learn about a novel, transdiagnostic and behaviourally focused formulation for use in clinical practice.

Abstract
This study evaluated the psychometric properties and factor structure of the Calgary Depression Scale for Schizophrenia (CDSS) across different levels of the schizotypy continuum. A combined sample of high-schizotypy, at-risk mental states, and patients with first-episode psychosis was assessed for depression and other clinical and functional outcomes. Additionally, experience sampling methodology was used to assess depressive and psychotic-like experiences in daily life. The CDSS exhibited solid internal consistency, validity, and discrimination between depressed and nondepressed participants. Confirmatory factor analyses and the associations of the resulting factors with clinical and functional measures supported a two-factor structure that included general depression and guilt factors. Furthermore, both factors of the CDSS were differentially related to positive and negative symptoms of psychosis in daily life. The CDSS appears to have two underlying psychopathological dimensions and to be a reliable and valid measure for assessing depression across the schizotypy continuum.

Abstract
OBJECTIVE Experience sampling assessments (multiple assessments per day for approximately one week) indicate that positive symptoms fluctuate over time in psychosis. Precursors, such as sleep problems or worrying, predict these fluctuations. To date, it remains unclear whether the same precursors predict symptom variability also during treatment in an online intervention for psychosis, using assessments lying temporally further apart. METHODS Participants completed brief intermediate online self-report assessments on their computers (up to every 7 days during a 2-month waiting period and up to twice every 6 days during a 2-month intervention period) within a randomized controlled trial. We monitored the course of paranoia, auditory verbal hallucinations, and their theory-driven precursors worrying, negative affect, self-esteem, self-reported cognitive biases, and quality of sleep in n = 124 participants (M = 10.32 assessments per participant; SD = 6.07). We tested group differences regarding the course of the composite of precursors, group differences regarding the effect of the composite on subsequent momentary psychotic symptoms, and the effect of each individual precursor on subsequent psychotic symptoms, using (lagged) linear mixed models. RESULTS The course composite precursors over time and their lagged effect on subsequent momentary psychotic symptoms did not differ between groups. During the intervention, increased worrying and decreased quality of sleep preceded heightened momentary psychotic symptoms. CONCLUSION The regression-based design does not allow drawing causal conclusions. However, worrying and sleep problems likely represent underlying mechanisms of psychotic symptom variability during online psychosis treatment, indicating that experience sampling findings from everyday life generalize to interventions with assessments lying several days apart. PRACTITIONER POINTS Worrying and sleep problems represent important mechanisms of symptom fluctuations during an online intervention for people with psychosis. Our findings further support the notion that worrying and sleep problems are important treatment targets in psychological interventions for people with psychosis. Momentary levels of worrying and quality of sleep can signal subsequent fluctuations of psychotic symptom severity so practitioners should monitor these variables during treatment. Worrying seems to predict subsequent paranoia specifically during treatment whereas quality of sleep predicts both paranoia and auditory verbal hallucinations.

Abstract
The association between childhood adversity (CA) and psychosis has been extensively investigated in recent years. An increasing body of research has also focused on the mediating or moderating role of biological and psychological mechanisms, as well as other risk factors that might account for the link between CA and psychosis. We conducted a systematic search of the PsychINFO, Embase, Ovid, and Web of Science databases for original articles investigating the role of genetic vulnerabilities, environmental factors, psychological and psychopathological mechanisms in the association between CA and psychosis up to August 2019. We included studies with individuals at different stages of the psychosis continuum, from subclinical psychotic experiences to diagnosed disorders. From the 28 944 records identified, a total of 121 studies were included in this review. Only 26% of the studies identified met the criteria for methodological robustness. Overall, the current evidence suggests that CA may be associated with psychosis largely independently of genetic vulnerabilities. More consistent and robust evidence supports interaction between early and recent adversities, as well as the mediating role of attachment and mood symptoms, which is suggestive of an affective pathway between CA and psychosis across the continuum from subclinical experiences to diagnosable disorder. This review highlighted numerous methodological issues with the existing literature, including selection bias, heterogeneity of measurement instruments utilised, and lack of control for potential confounders. Future research should address these limitations to more accurately estimate mediation and moderation effects on the CA-psychosis association to inform the development of preventive interventions.

Subclinical paranoid beliefs and enhanced neural response during processing of unattractive faces. NEUROIMAGE-CLINICAL 2020; 27:102269.

Abstract
The perception of faces and consequent social inferences are fundamental for interpersonal communication. While facial expression is important for interindividual communication, constitutional and acquired features are crucial for basic emotions of attraction or repulsion. An emotional bias in face processing has been shown in schizophrenia, but the neurobiological mechanisms are unclear. Studies on the interaction between face processing and the emotional state of healthy individuals may help to elucidate the pathogenesis of the paranoid syndrome in psychosis. This study addressed facial attractiveness and paranoid ideas in a non-clinical population. Using functional magnetic resonance imaging (fMRI), we investigated neural activation patterns of 99 healthy subjects during the passive perception of a dynamic presentation of faces with different attractiveness. We found that the perceived attractiveness of faces was linked to the activity of face processing and limbic regions including the fusiform gyrus, amygdala, and prefrontal areas. Paranoid beliefs interacted with perceived attractiveness in these regions resulting in a higher response range and increased activation after the presentation of unattractive faces. However, no behavioral interactions between reported subjective attractiveness and paranoid beliefs were found. The results showed that increased activation of limbic brain regions is linked to paranoid beliefs. Since similar correlations were found in clinical populations with paranoid syndromes, we suggest a dimension of emotional dysregulation ranging from subclinical paranoid beliefs to paranoid schizophrenia.

Abstract
Objectives It is common, among clinical and non-clinical populations alike, for paranoia and anxiety to co-occur. It has been suggested that anxiety and its related appraisal styles may contribute to development of paranoia. We aimed to evaluate different aspects of risk perception in relation to paranoia and anxiety and to identify specific aspects that may differentiate paranoia from anxiety. This paper consists of two inter-related studies. Methods Study 1 compared 30 patients with persecutory delusions, 21 patients with generalized anxiety disorder and 52 healthy controls. Study 2 compared 30 non-clinical individuals with high levels of paranoia and anxiety, 28 individuals with high anxiety only and 36 healthy controls. Within each study, the two symptomatic groups were matched on level of anxiety. Four dimensions of risk perception (i.e. likelihood, harm, controllability, and intentionality) were compared across groups, as measured by the locally validated Risk Perception Questionnaire. Results In both studies, the paranoia and the anxiety groups reported an elevated perceived likelihood of negative events than controls respectively. Only the paranoia groups reported an elevated perceived harm of neutral events than controls. In Study 2, the two at-risk groups attributed more harm and intentionality to negative events than controls. Conclusion Although perception of negative events was characteristic in anxiety (with or without paranoia), a biased perception of neutral events as risky was unique to the addition of paranoia. Implications to the transdiagnostic and continual view of psychopathology, and mechanism-based interventions were discussed.

Abstract
Emotions play a key role in the development and experience of psychosis, yet there are important gaps in our understanding of how individuals with psychosis understand and respond to their emotions. This systematic review investigated self-reported emotion regulation difficulties in individuals with psychosis compared with non-clinical controls. An electronic database search was conducted in Medline, PsychINFO, and Embase and supplemented by searches of reference lists and citations. Seventeen studies were included. A narrative synthesis was conducted because contextual diversity was present across the studies and outcomes. Individuals with psychosis reported greater difficulties in (i) emotional clarity (specifically with identifying, describing, and understanding their emotions), (ii) emotional acceptance, (iii) engaging in goal-directed behaviours when experiencing negative emotions, and (iv) willingness to experience emotional distress in the pursuit of meaningful activities in life. Evidence pertaining to other self-reported emotion regulation difficulties was less clear. Effect sizes were generally large in magnitude but there were few studies on some self-reported emotion regulation difficulties, and all studies were at moderate to high risk of bias. Further research is needed to clarify the nature of emotion regulation difficulties in individuals with psychosis to inform the provision of targeted clinical interventions.

Abstract
Increased FA of bilateral slMFB can be found in delusional SSD-patients. Findings are supported by a psychopathological model of paranoia and grandiosity. Findings are in line with a model of underlying network physiology (slMFB).
In many cases delusions in schizophrenia spectrum disorders (SSD) are driven by strong emotions such as feelings of paranoia or grandiosity. We refer to these extreme emotional experiences as psychotic affectivity. We hypothesized that increased structural connectivity of the supero-lateral medial forebrain bundle (slMFB), a major tract of the reward system, is associated with delusional psychotic affectivity. Forty-six patients with SSD and 44 healthy controls (HC) underwent diffusion weighted magnetic resonance imaging (DW-MRI)-scans. The slMFB and a comparison tract (corticospinal tract) were reconstructed using diffusion tensor imaging (DTI)-based tractography. Fractional anisotropy (FA) was sampled across the tracts. We used a mixed-model analyses of variance controlling for age and gender to compare FA of bilateral slMFB between SSD-patients and HC. Correlations of FA of bilateral slMFB and the PANSS-positive item delusions were calculated. In addition, FA was compared between three clinically homogeneous SSD-subgroups in terms of psychotic affectivity (severe, mild and no PA, sPA, mPA, nPA) and HC. FA of the slMFB did not differ between all SSD-patients and HC. In SSD-patients there was a positive correlation between delusions and FA in bilateral slMFB. Likewise, SSD-subgroups of psychotic affectivity and HC differed significantly in FA of the slMFB. Results were driven by higher FA in the right slMFB in sPA as compared to nPA and to HC. There was no significant effect for the comparison tract. In conclusion, increased structural connectivity of the slMFB may underlie delusional experiences of paranoia and grandiosity in SSD.

Abstract
INTRODUCTION Pathological confidence in one's thoughts is a key mechanism of chronic paranoid thinking. For this reason, many of the current therapies focus on trying to reduce it. In fact, the way some antipsychotics (e.g., haloperidol) work seems to be through the induction of doubt. Because of the impact of these pathological thoughts on positive health, studying the well-being of people who experience paranoid thoughts is fundamental. The first objective of this research is to apply the Complete State Model of Health (CSMH) to a sample of patients characterized by the presence of paranoid thinking. Our second objective is to evaluate the impact of therapies based on reducing pathological confidence on patients' well-being. METHODS Sixty participants with SCID-5 confirmed DSM-5 diagnosis related with paranoid thinking and without mood symptoms were recruited. In order to test the existence of a two continua model of mental health (CSMH), we conducted a parallel analysis and an exploratory factor analysis. To test our hypothesis regarding the partially mediating role of doubt between paranoid thinking and patients' well-being, we conducted a biased corrected bootstrapping procedure. RESULTS As expected, two different unipolar dimensions emerged from the measures used to assess paranoid thinking and positive health (two continua model of mental health). When patients received metacognitive and pharmacological treatment, more paranoid thinking led to more doubt in all thoughts, which in turn affected well-being. The analyses carried out confirmed the partial mediating role of doubt. CONCLUSION Despite the efficacy shown by both metacognitive therapies and antipsychotics, it seems that they not only reduce pathological confidence, but can also affect other thoughts not linked to delirium. This effect of generalization of doubt in all thoughts negatively affected patients' well-being and quality of life.

Reading characters in voices: Ratings of personality characteristics from voices predict proneness to auditory verbal hallucinations. PLoS One 2019; 14:e0221127.

Abstract
People rapidly make first impressions of others, often based on very little information–minimal exposure to faces or voices is sufficient for humans to make up their mind about personality of others. While there has been considerable research on voice personality perception, much less is known about its relevance to hallucination-proneness, despite auditory hallucinations being frequently perceived as personified social agents. The present paper reports two studies investigating the relation between voice personality perception and hallucination-proneness in non-clinical samples. A voice personality perception task was created, in which participants rated short voice recordings on four personality characteristics, relating to dimensions of the voice’s perceived Valence and Dominance. Hierarchical regression was used to assess contributions of Valence and Dominance voice personality ratings to hallucination-proneness scores, controlling for paranoia-proneness and vividness of mental imagery. Results from Study 1 suggested that high ratings of voices as dominant might be related to high hallucination-proneness; however, this relation seemed to be dependent on reported levels of paranoid thinking. In Study 2, we show that hallucination-proneness was associated with high ratings of voice dominance, and this was independent of paranoia and imagery abilities scores, both of which were found to be significant predictors of hallucination-proneness. Results from Study 2 suggest an interaction between gender of participants and the gender of the voice actor, where only ratings of own gender voices on Dominance characteristics are related to hallucination-proneness scores. These results are important for understanding the perception of characterful features of voices and its significance for psychopathology.

Abstract
BACKGROUND Evidence suggests that cannabis use, childhood adversity, and urbanicity, in interaction with proxy measures of genetic risk, may facilitate onset of psychosis in the sense of early affective dysregulation becoming 'complicated' by, first, attenuated psychosis and, eventually, full-blown psychotic symptoms. METHODS Data were derived from three waves of the second Netherlands Mental Health Survey and Incidence Study (NEMESIS-2). The impact of environmental risk factors (cannabis use, childhood adversity, and urbanicity) was analyzed across severity levels of psychopathology defined by the degree to which affective dysregulation was 'complicated' by low-grade psychotic experiences ('attenuated psychosis' - moderately severe) and, overt psychotic symptoms leading to help-seeking ('clinical psychosis' - most severe). Familial and non-familial strata were defined based on family history of (mostly) affective disorder and used as a proxy for genetic risk in models of family history × environmental risk interaction. RESULTS In proxy gene-environment interaction analysis, childhood adversity and cannabis use, and to a lesser extent urbanicity, displayed greater-than-additive risk if there was also evidence of familial affective liability. In addition, the interaction contrast ratio grew progressively greater across severity levels of psychosis admixture (none, attenuated psychosis, clinical psychosis) complicating affective dysregulation. CONCLUSION Known environmental risks interact with familial evidence of affective liability in driving the level of psychosis admixture in states of early affective dysregulation in the general population, constituting an affective pathway to psychosis. There is interest in decomposing family history of affective liability into the environmental and genetic components that underlie the interactions as shown here.

Abstract
AIM Psychotic experiences, including delusions and hallucinations, and their attenuated forms have been recently suggested as a significant but under-recognized marker of suicide risk. However, the relationship between attenuated positive symptoms and suicide has not yet been clearly demonstrated in individuals at ultra-high risk (UHR) for psychosis. Here, we investigated the effect of attenuated positive symptoms on suicidal ideation in UHR individuals. METHODS Fifty-three healthy controls (HCs) and 74 UHR individuals participated in the present study. All participants were assessed for the intensity of suicidal ideation and depressive symptoms at baseline. The effect of attenuated positive symptoms on suicidal ideation in the UHR group was examined using a multiple linear regression analysis after adjustment for concurrent depressive symptoms. RESULTS UHR participants were found to have significantly greater suicidal ideation and more severe depressive symptoms compared to those of HCs. The regression model demonstrated that suspiciousness significantly increased suicidal ideation in UHR participants, independent of the severity of depressive symptoms. CONCLUSION The findings of the present study suggest that suspiciousness may serve as a risk indicator for suicide in clinical practice for UHR individuals. It is crucial to focus on the risk of suicide in the UHR population, as they require sufficient clinical attention and proper management for crises related to their unusual and confusing experiences.

Abstract
Epidemiological studies have suggested that maternal diabetes in pregnancy increases the risk of schizophrenia in offspring. A recent cohort study observed that maternal diabetes in early pregnancy is also associated with psychotic experiences in the general adolescent population. However, it remains unclear whether maternal diabetes in early pregnancy is specifically associated with psychotic experiences, or is generally associated with broader mental health problems, including depressive symptoms in adolescence. The present study investigated the longitudinal associations between maternal diabetes in early pregnancy, and psychotic experiences and depressive symptoms in 10-year-old offspring. Our data were derived from the Tokyo Early Adolescence Survey, a population-based survey of early adolescents (N = 4478) and their primary caregivers. Diabetes in early pregnancy was determined by records in the mother's Maternal and Child Health Handbook, documented during the pregnancy. Psychotic experiences and depressive symptoms were established through self-report by the offspring at 10 years of age. Diabetes in early pregnancy was associated with an increased risk of hallucination in the offspring (auditory hallucination [odds ratio {OR} 4.33, 95% confidence interval {CI} 1.12-16.75]; visual hallucination [OR 6.58, 95% CI 1.69-25.66]), even after adjusting for depressive symptoms and other covariates. However, the association between maternal diabetes and delusional thoughts was not significant and diabetes in early pregnancy was not associated with adolescent depressive symptoms. Our investigation suggests that maternal diabetes in early pregnancy may specifically affect the risk of hallucinatory experiences in adolescent offspring.

Abstract
OBJECTIVE Facial expressions communicate emotional states and regulate social bonds. An approach or avoidance-based valence might interact with direct or averted gaze to elicit different attentional allocation. These processes might be aberrant in major depression or first-episode psychosis and this requires empirical investigation. METHOD This study examined higher order, controlled attentional processing of emotional facial expressions (happy, neutral, angry and fearful), with direct or averted gaze, using electroencephalogram (EEG) measures of the face-elicited Late Positive Potential (LPP), in young people diagnosed with major depression or first-episode psychosis, compared with a healthy control group. RESULTS In the control group, there was no evidence of increased attentional allocation to emotional facial expressions, or to facial expressions with a matching emotional expression and gaze direction. There was no evidence, in the depression or first-episode psychosis groups, for a threat-based, attentional hypersensitivity to fearful or angry facial expressions, nor for this effect to be potentiated in response to angry direct or fearful averted gaze faces. However, the absence of such effects could not be concluded due to sample size and the absence of stimulus arousal and valence ratings. Importantly, there was significantly increased attentional allocation in the first-episode psychosis group to facial expressions regardless of emotional expression or gaze direction, compared to both the depression and control group. CONCLUSIONS There might be an attentional hypersensitivity to facial expressions regardless of emotional expression or gaze direction in first-episode psychosis.

Abstract
Theorists, clinicians, and investigators have attempted to find a common source for the negative and positive symptoms of schizophrenia. We propose that a unified theory, based on a common cognitive structure not only has explanatory value, but can serve as a framework for a psychotherapeutic intervention. Specifically, we propose that the cognitive triad - the negative view of the self, others, and the future - is the source of the content for the negative and positive symptoms. We report literature supporting the relationship between each facet of the negative triad and each of the key symptoms: expressive negative symptoms, delusions, and verbal hallucinations. We conclude that the literature supports the validity of the cognitive model of negative and positive symptoms. The cognitive model furthers the understanding of the positive and negative symptoms of schizophrenia, and we describe how this provides a framework for a psychotherapeutic intervention.

Abstract
The vigilance-avoidance hypothesis of paranoia states that in paranoia visual attention is shifted away from threat-related stimuli. This may be an explanation for reduced scanning of salient facial features in psychosis and subsequently impaired emotion recognition. Here, we explored whether higher levels of paranoia would predict reduced visual attention to salient facial features and impaired emotion recognition and whether reduced visual attention to salient facial features mediates the association between paranoia and errors in emotion recognition. Participants with schizophrenia (SZ, n = 22) and healthy controls (HC, n = 19) completed questionnaire assessments of paranoia and negative symptoms and conducted an emotion recognition task comprised of dynamic facial stimuli. Additionally, visual attention (number of fixations) to salient facial features was assessed using eye-tracking. SZ made more errors in affect recognition than HC. Visual attention to salient facial features did not differ between SZ and HC but significantly mediated the significant association between paranoia and errors in the emotion recognition task in the complete sample. Negative symptoms also predicted errors in emotion recognition but this association was not mediated by visual attention. Our findings are in line with the avoidance-assumption of a vigilance-avoidance hypothesis of paranoia, in which correct facial emotion recognition is prevented due to an avoidance of salient facial features.

Abstract
BACKGROUND The anticipation of threat or victimization is a core feature of paranoia. Cognitive theories of paranoia suggest that paranoid thoughts may arise as a psychological response to trauma exposure, which likewise may lead to greater anticipation of subsequent victimization. Little is known, however, about the relation between paranoid beliefs and anticipated victimization when accounting for past victimization experience. The present study aimed to address whether the experiences of past victimization contribute to the link between paranoid beliefs and the anticipation of threat or victimization, with a particular focus on exposure to police violence. METHODS Data were collected through the Survey of Police-Public Encounters (N=1615), a cross-sectional, general population survey study conducted in four Eastern U.S. cities. Associations between paranoia and anticipated victimization were assessed using linear regression models, with and without adjustment for past victimization exposure. RESULTS Paranoid beliefs were positively associated with police victimization expectations (β=0.19, p<0.001), but these associations were statistically better explained by past exposures to similar victimization such that paranoia was no longer associated with anticipated victimization in adjusted models (β=0.02, p=0.451). To assess for the specificity of past exposures to victimization, adjusting for past exposure to intimate partner violence (as a control condition) did not eliminate the association between paranoia and expected police victimization. CONCLUSIONS The overall findings are consistent with cognitive theories of paranoia in which paranoid beliefs may be a severe but normative reaction to past victimization exposures in some cases.

Abstract
BACKGROUND AND OBJECTIVES When asked to evaluate faces of strangers, people with paranoia show a tendency to rate others as less trustworthy. The present study investigated the impact of arousal on this interpersonal bias, and whether this bias was specific to evaluations of trust or additionally affected other trait judgements. The study also examined the impact of eye gaze direction, as direct eye gaze has been shown to heighten arousal. METHODS In two experiments, non-clinical participants completed face rating tasks before and after either an arousal manipulation or control manipulation. Experiment one examined the effects of heightened arousal on judgements of trustworthiness. Experiment two examined the specificity of the bias, and the impact of gaze direction. RESULTS Experiment one indicated that the arousal manipulation led to lower trustworthiness ratings. Experiment two showed that heightened arousal reduced trust evaluations of trustworthy faces, particularly trustworthy faces with averted gaze. The control group rated trustworthy faces with direct gaze as more trustworthy post-manipulation. There was some evidence that attractiveness ratings were affected similarly to the trust judgements, whereas judgements of intelligence were not affected by higher arousal. LIMITATIONS In both studies, participants reported low levels of arousal even after the manipulation and the use of a non-clinical sample limits the generalisability to clinical samples. CONCLUSIONS There is a complex interplay between arousal, evaluations of trustworthiness and gaze direction. Heightened arousal influences judgements of trustworthiness, but within the context of face type and gaze direction.

Abstract
Negative emotions and cognitive biases are important factors underlying psychotic symptoms and psychotic-like experiences (PLEs); however, it is not clear whether these factors interact when they influence psychotic phenomena. The aim of our study was to investigate whether psychosis-related cognitive biases moderate the relationship between negative affective states, i.e. anxiety and depression, and psychotic-like experiences. The study sample contains 251 participants who have never been diagnosed with psychiatric disorders. Anxiety, depression, cognitive biases, and psychotic-like experiences were assessed with self-report questionnaires. A moderation analysis was performed to examine the relationship between the study variables. The analyses revealed that the link between anxiety and positive PLEs is moderated by External Attribution bias, whereas the relationship between depression and positive PLEs is moderated by Attention to Threat bias. Attributional bias was also found to moderate the association between depression and negative subclinical symptoms; Jumping to Conclusions bias served as a moderator in the link between anxiety and depression and negative PLEs. Further studies in clinical samples are required to verify the moderating role of individual cognitive biases on the relationship between negative emotional states and full-blown psychotic symptoms.

Abstract
BACKGROUND The observed link between positive psychotic experiences (PE) and psychosis spectrum disorder (PSD) may be stronger depending on concomitant presence of PE with other dimensions of psychopathology. We examined whether the effect of common risk factors for PSD on PE is additive and whether the impact of risk factors on the occurrence of PE depends on the co-occurrence of other symptom dimensions (affective dysregulation, negative symptoms, and cognitive alteration). METHOD Data from the Netherlands Mental Health Survey and Incidence Study 2 were used. Risk factors included childhood adversity, cannabis use, urbanicity, foreign born, hearing impairment, and family history of affective disorders. Logistic regression models were applied to test (1) the additive effect of risk factors (4 levels) on PE and (2) the moderating effects of symptom dimensions on the association between risk factors (present/absent) and PE, using additive interaction, expressed as the interaction contrast ratio. RESULTS Risk factors were additive: the greater the number of risk factors, the greater the odds of PE. Furthermore, concomitant presence of the other symptom dimensions all increased the impact of risk factors on PE. After controlling for age, sex, and education, only affective dysregulation and negative symptoms remained significant moderators; only affective dysregulation remained a significant moderator if all dimensions were adjusted for each other. CONCLUSIONS Risk factors may not be directly associated with PE but additively give rise to a multidimensional subthreshold state anticipating the multidimensional clinical syndrome. Early motivational and cognitive impairments in the context of PE may be reducible to affective dysregulation.

Abstract
OBJECTIVES It is increasingly accepted that paranoia lies on a continuum of severity that can be observed in the general population. Several psychological factors have been implicated in the development of more distressing persecutory ideas including negative affect (i.e., anxiety and depression), beliefs about oneself and other people (i.e., schemas), and metacognitive beliefs. This study aimed to explore the combined role of cognition and metacognition in paranoia. Specifically, unhelpful metacognitive beliefs and schematic beliefs were tested as potential moderators of the relationship between non-clinical paranoid ideation and negative affect. METHODS Measures from 227 people who took part in a cross-sectional online survey were analysed using structural equation modelling. A series of models grounded in cognitive and metacognitive theory were tested sequentially. RESULTS The results demonstrated that unhelpful metacognitive beliefs had a positive moderating effect on the relationship between paranoia and negative affect. Negative beliefs about oneself and other people did not moderate negative affect but positive beliefs about other people had a negative moderating effect. In a final model, negative schematic beliefs predicted paranoid ideation whilst metacognitive beliefs predicted and moderated affect. CONCLUSIONS The findings suggest that consideration of metacognitive beliefs, as well as schemas, may be important in understanding non-clinical paranoia. PRACTITIONER POINTS Metacognitive beliefs may be an important determinant of negative affect in the context of non-clinical paranoia. The consideration of both cognitive and metacognitive factors may be helpful when working with people with distressing paranoid ideas.

Abstract
BACKGROUND Traumatic life events have been established as an environmental risk factor for psychosis. However, the exact mechanisms by which traumatic life events increase risk for psychosis are unknown. In the present study we tested an integrative model of traumatic life events being related to psychosis proneness via self-disturbances and cognitive biases. METHODS The sample consisted of 653 healthy people. Traumatic life events, self-disturbances, cognitive biases and psychosis proneness were assessed with self-report questionnaires. The direct and an indirect model of the relationship between traumatic life events and psychosis proneness were compared using path analyses with structural equation modelling in a cross-sectional study. RESULTS There was a significant direct effect of traumatic life events on psychosis proneness. However, path analysis suggested better fit of the indirect model including paths from trauma to psychosis proneness via cognitive biases and self-disturbances. There were significant paths from traumatic life events to cognitive biases and self-disorders. Self-disorders significantly predicted cognitive biases. Finally, cognitive biases and self-disorders significantly predicted psychosis proneness. Exclusion of any paths, apart from direct path in the model, significantly reduced model fitness. DISCUSSION The results revealed that a direct relationship between trauma and psychosis proneness became insignificant when taking into account the influence of self-disorders and cognitive biases. This suggests that the interactions between disrupted self-experience, impaired information processing and traumatic life events are of importance in psychosis proneness. This model should be further tested in a longitudinal study on a clinical sample.

A Possible Link between Anxiety and Schizophrenia and a Possible Role of Anhedonia. SCHIZOPHRENIA RESEARCH AND TREATMENT 2018; 2018:5917475.

Abstract
In the prodromal phase of schizophrenia, severe alterations of the visual appearance of the environment have been found, accompanied by a state of intense anxiety. The present study considers the possibility that these alterations really exist in the appearance of objects, but that healthy people do not see them. The image of the world that we see is continuously deformed and fragmented by foreshortenings, partial overlapping, and so on and must be constantly reassembled and interpreted; otherwise, it could change so much that we would hardly recognize it. Since pleasure has been found to be involved in visual and cognitive information processing, the possibility is considered that anhedonia (the reduction of the ability to feel pleasure) might interfere with the correct reconstruction and interpretation of the image of the environment and alter its appearance. The possibility is also considered that these alterations might make the environment hostile, might at times evoke the sensation of being trapped by a predator, and might be the cause of the anxiety that accompanies them. According to some authors, they might also induce delusional ideas, in an attempt to restore meaning in a world that has become chaotic and frightening.

Abstract
Although traumatic life events have been linked to psychotic-like experiences, the mechanisms of the relationship remain unclear. We investigated whether insecure (anxious and avoidant) attachment styles, cognitive biases and self-disturbances serve as significant mediators in the relationship between traumatic life events and psychotic-like experiences in non-clinical sample. Six-hundred and ninety healthy participants (522 females) who have not ever been diagnosed with psychiatric disorders took part in the study. Participants completed self-report scales that measure traumatic life events, psychotic-like experiences, cognitive biases, attachment styles and self-disturbances. Our model was tested with path analysis. Our integrated model fit to the data with excellent goodness-of-fit indices. The direct effect was significantly reduced after the mediators were included. Significant pathways from traumatic life events to psychotic-like experiences were found through self-disturbances and cognitive biases. Traumatic life events were associated with anxious attachment through cognitive biases. Self-disturbances, cognitive biases and anxious attachment had a direct effect on psychotic-like experiences. The results of our study tentatively suggest that traumatic life events are related with psychotic-like experiences through cognitive biases and self-disturbances. Further studies in clinical samples are required to verify our model.

Abstract
Depression and anxiety are prominent comorbid disorders in psychosis and relevant to psychotic symptom formation and maintenance. This poses the question of whether psychological interventions are effective in improving symptoms of depression and anxiety in patients with psychosis. A systematic review of the literature identified 14 studies evaluating a broad range of interventions targeting depression, anxiety, and posttraumatic stress disorder in patients with psychosis. The reviewed studies support the effectiveness of cognitive-behavioral interventions in improving the target symptoms. Further research is needed to examine whether the effects carry over to psychotic symptoms in the long term.

Abstract
Social anxiety (SA) is frequently observed among patients diagnosed with psychosis as well as among individuals with delusion-like experiences (DLEs). A heightened level of SA has been recognized to precede the development of psychotic symptoms; however, the detailed mechanisms that link SA to delusional ideation remain unrecognized. Since social anxiety is associated with the presence of cognitive biases and biased cognitive processes have been found to play a role in the development and maintenance of delusions, we hypothesized that cognitive biases may mediate in the relationship between social anxiety and DLEs. A total sample of 202 healthy individuals with mean age 35.59 (SD = 17.15) was assessed for the presence of delusion-like experiences, social anxiety, as well as the threatening events theme and anomalous perception theme of cognitive biases. The threatening events theme was found to fully mediate the linkage between fear of social situations and DLEs (β = 0.12, p < 0.05). The threatening events theme was also found to be a partial mediator in the association between social avoidance and DLEs (β = 0.20, p < 0.05), and between the overall level of social anxiety and DLEs (β = 0.18, p < 0.05). Our findings suggest that social anxiety may influence DLEs by providing the threatening events theme of cognitive biases.
