Abstract
BACKGROUND AND HYPOTHESIS Trauma is a robust risk factor for delusional ideation. However, the specificity and processes underlying this relationship are unclear. Qualitatively, interpersonal traumas (i.e., trauma caused by another person) appear to have a specific relationship with delusional ideation, particularly paranoia, given the commonality of social threat. However, this has not been empirically tested and the processes by which interpersonal trauma contributes to delusional ideation remain poorly understood. Given the role of impaired sleep in both trauma and delusional ideation, it may be a critical mediator between these variables. We hypothesized that interpersonal trauma, but not non-interpersonal trauma, would be positively related to subtypes of delusional ideation, especially paranoia, and that impaired sleep would mediate these relationships. STUDY DESIGN In a large, transdiagnostic community sample (N = 478), an exploratory factor analysis of the Peter's Delusion Inventory identified three subtypes of delusional ideation, namely magical thinking, grandiosity, and paranoia. Three path models, one for each subtype of delusional ideation, tested whether interpersonal trauma and non-interpersonal trauma were related to subtypes of delusional ideation, and impaired sleep as a mediating variable of interpersonal trauma. STUDY RESULTS Paranoia and grandiosity were positively related to interpersonal trauma and unrelated to non-interpersonal trauma. Furthermore, these relationships were significantly mediated by impaired sleep, which appeared strongest for paranoia. In contrast, magical thinking was unrelated to traumatic experiences. CONCLUSIONS These findings support a specific relationship between interpersonal trauma and paranoia as well as grandiosity, with impaired sleep appearing as an important process by which interpersonal trauma contributes to both.

Abstract
In his book Aion, Jung describes something like a quasi-Hegelian progressive historical realization of the Self in a perspective similar to Fernand Braudel's longue durée history. This article deals with a similar perspective, as it tries to focus on what we may call a "cultural complex" yet within its unfolding in historical time and belonging not to just one specific cultural group, but to a large cultural basin, which we may indicate as the "West". This complex marks the birth and development of modernity. The depth, pervasiveness and duration of this cultural complex permeates the lives and psychologies of all of those that are part of it. Therefore, every analytical project must take into account the underlying emotional, epistemic and social field within which this complex constellates. One of the main features of this (trans)cultural complex, strictly connected with the progressive fragmentation of the self and the transformation of the numinosum with its meaning-giving force, is paranoia. This article analyses the historical and cultural features that produce paranoia and fragmentation and determine paranoid symptoms and attitudes.

Abstract
There is a general consensus that personality disorders (PDs) share a general factor (g-PD) overlapping with the general factor of psychopathology (p-factor). The general psychopathology factor is related to many social dysfunctions, but its nature still remains to some extent ambiguous. We posit that hostile attributions may be explanatory for the factor common for all PDs, i.e., interpersonal problems and difficulty in building long-lasting and satisfying relationships of all kinds. Thus, the main objective of the current project was to expand the existing knowledge about underlying factors of g-PD with regard to hostile attributions. We performed a cross-sectional study on a representative, community sample of Poles (N = 1031). Our hypotheses were primarily confirmed as hostile attributions predicted p-factor. However, the relation was positive only for hostile attributions related to ambiguous situations involving relational harm and physical harm done by female authorities and negative in case of hostile attributions in situations involving physical harm done by peers. Additionally, paranoia-like thoughts strongly related to hostile attributions and independently predicted g-PD. The results contribute to the current discussion on the nature of the g-PD, confirm that hostile attributions and paranoia are a crucial aspect of personality pathology, and indicate the importance of working on these cognitions in the course of therapeutic work.

Abstract
PURPOSE Insecure attachment may constitute a vulnerability factor for psychosis, and dissociation may be a key mechanism in the development of auditory hallucinations specifically. While there is good evidence for the role of these processes in isolation, it is unclear whether dissociation accounts for the association between insecure attachment and psychosis. This systematic review takes a theory-driven approach to examine proposed causal relationships across the clinical and nonclinical literature. METHODS We searched five databases (PubMeD, Web of Science, PsycINFO, CINAHL and ETHOS) for published and unpublished research examining attachment, dissociation and psychosis. Two independent reviewers extracted the data and assessed the quality of all included studies. RESULTS We identified 242 potential articles and included 13 in the final review (2096 participants). We found that (1) disorganised attachment was consistently associated with dissociation and inconsistently associated with voices and paranoia, (2) dissociation was associated with voices and paranoia, and these links were stronger in clinical samples, and (3) dissociation played a role in the impact of insecure attachment on voice hearing and paranoia in clinical groups. CONCLUSIONS This is the first review to synthesise the research examining attachment, dissociation, and psychosis. The evidence is consistent with proposed causal hypotheses and raises conceptual and measurement issues, for example, the need to clarify the relative contributions of different insecure attachment styles, and utilise behavioural/observational measures to strengthen study designs. Most importantly, we need experimental and longitudinal studies to confirm causal links and targets for treatment.

Abstract
AIM Psychotic-like experiences (PLEs) are experiences in the general population that, in their extreme form, are attributed to clinical psychosis. They are correlated with general psychopathology and increased risk of developing psychosis. Previous research show a multitude of measuring tools which most often lack psychometric validation. This study aimed to examine both categorical and metacognitive measures of PLEs. METHODS Confirmatory Factor Analysis (CFA) was used in seven online studies with n's ranging from 259 to 6772 to explore factor structures of Prodromal Questionnaire 16 item (PQ-16), Revised Green et al. Paranoid Thoughts Scale (R-GPTS), Multi-Modality Unusual Sensory Experiences Questionnaire (MUSEQ), Beliefs about Paranoia Scale (BAPS) and Interpretation of Voices Inventory (IVI). Additionally, we explored measurement invariance between diagnosed with psychiatric disorders and undiagnosed individuals in PQ-16, R-GPTS and BAPS. RESULTS We confirmed the factor structures of all questionnaires except IVI. We confirmed configural, threshold and metric measurement invariance in R-GPTS and BAPS and partially PQ-16. CONCLUSIONS The current results demonstrate structural validity and measurement invariance of several categorical and metacognitive measures of PLEs.

Abstract
BACKGROUND With efforts increasing worldwide to understand and treat paranoia, there is a pressing need for cross-culturally valid assessments of paranoid beliefs. The recently developed Revised Green et al., Paranoid Thoughts Scale (R-GPTS) constitutes an easy to administer self-report assessment of mild ideas of reference and more severe persecutory thoughts. Moreover, it comes with clinical cut-offs for increased usability in research and clinical practice. With multiple translations of the R-GPTS already available and in use, a formal test of its measurement invariance is now needed. METHODS Using data from a multinational cross-sectional online survey in the UK, USA, Australia, Germany, and Hong Kong (N = 2510), we performed confirmatory factory analyses on the R-GPTS and tested for measurement invariance across sites. RESULTS We found sufficient fit for the two-factor structure (ideas of reference, persecutory thoughts) of the R-GPTS across cultures. Measurement invariance was found for the persecutory thoughts subscale, indicating that it does measure the same construct across the tested samples in the same way. For ideas of reference, we found no scalar invariance, which was traced back to (mostly higher) item intercepts in the Hong Kong sample. CONCLUSION We found sufficient invariance for the persecutory thoughts scale, which is of substantial practical importance, as it is used for the screening of clinical paranoia. A direct comparison of the ideas of reference sum-scores between cultures, however, may lead to an over-estimation of these milder forms of paranoia in some (non-western) cultures.

Abstract
Wherever psychopathology operates with the concept of (disorders of) the self and personality, it can address the role of the intuitive access we have toward ourselves, others, and the world. This study discusses the concept of oikeiôsis. It examines its role in explaining paranoia as a change in intuitive self-and-world relatedness. In the first step, symptomatic features of paranoid personality disorder are sketched, with a focus on the explanatory role of attentional and interpretative biases, which correlate with significant changes in intuitive processing. In the second step, the prototypical phenomenality of feelings of unfamiliarity and mistrust are discussed against the backdrop of changes of oikeiôsis in paranoid personality disorder. In the third step, the main therapeutic challenge in treating paranoid personality disorder-building a trustful relationship-is explored. It is concluded that the notion of oikeiôsis resonates particularly with introspection-based therapeutic approaches.

Abstract
Little is known about effective psychosocial treatments for paranoid personality disorder. This study explores the feasibility of a novel treatment, namely Evolutionary Systems Therapy, in supporting individuals diagnosed with paranoid personality disorder. Seven patients attended 10 months of individual therapy without receiving any psychopharmacological treatment. The primary outcome was the feasibility of the intervention, while the secondary outcomes were remission from the diagnosis and reliable changes in personality pathology and paranoid ideation. All recruited patients completed the intervention and did not report any adverse events. Six out of seven patients experienced remission from the diagnosis of paranoid personality disorder. All participants showed reliable changes in personality pathology and paranoid ideation, which were maintained at the 1-month follow-up. Further research is needed to confirm these encouraging results.

Abstract
BACKGROUND Paranoia is a highly debilitating mental health condition. One novel intervention for paranoia is cognitive bias modification for paranoia (CBM-pa). CBM-pa comes from a class of interventions that focus on manipulating interpretation bias. Here, we aimed to develop and evaluate new therapy content for CBM-pa for later use in a self-administered digital therapeutic for paranoia called STOP ("Successful Treatment of Paranoia"). OBJECTIVE This study aimed to (1) take a user-centered approach with input from living experts, clinicians, and academics to create and evaluate paranoia-relevant item content to be used in STOP and (2) engage with living experts and the design team from a digital health care solutions company to cocreate and pilot-test the STOP mobile app prototype. METHODS We invited 18 people with living or lived experiences of paranoia to create text exemplars of personal, everyday emotionally ambiguous scenarios that could provoke paranoid thoughts. Researchers then adapted 240 suitable exemplars into corresponding intervention items in the format commonly used for CBM training and created 240 control items for the purpose of testing STOP. Each item included newly developed, visually enriching graphics content to increase the engagement and realism of the basic text scenarios. All items were then evaluated for their paranoia severity and readability by living experts (n=8) and clinicians (n=7) and for their item length by the research team. Items were evenly distributed into six 40-item sessions based on these evaluations. Finalized items were presented in the STOP mobile app, which was co-designed with a digital health care solutions company, living or lived experts, and the academic team; user acceptance was evaluated across 2 pilot tests involving living or lived experts. RESULTS All materials reached predefined acceptable thresholds on all rating criteria: paranoia severity (intervention items: ≥1; control items: ≤1, readability: ≥3, and length of the scenarios), and there was no systematic difference between the intervention and control group materials overall or between individual sessions within each group. For item graphics, we also found no systematic differences in users' ratings of complexity (P=.68), attractiveness (P=.15), and interest (P=.14) between intervention and control group materials. User acceptance testing of the mobile app found that it is easy to use and navigate, interactive, and helpful. CONCLUSIONS Material development for any new digital therapeutic requires an iterative and rigorous process of testing involving multiple contributing groups. Appropriate user-centered development can create user-friendly mobile health apps, which may improve face validity and have a greater chance of being engaging and acceptable to the target end users.

Abstract
Background Reliable and valid assessment of paranoia is important in forensic psychiatry for providing adequate care. VR technology may add to current assessment procedures, as it enables observation within realistic (social) situations resembling the complexity of everyday life. VR constitutes a promising tool within forensics, due to the restricted nature of forensic psychiatric hospitals and ethical challenges arising from observing potentially dangerous behaviors in real life. Objective To investigate the feasibility of VR assessment for paranoid ideation in forensic psychiatric inpatients qualitatively by assessing the experiences of patients and a clinician, and to explore how the VR measures relate to established clinical measures. Methods One clinician (experienced psychiatrist) and 10 forensic psychiatric inpatients with a history or suspicion of paranoid ideation were included. Patients participated in two immersive VR scenarios (bus and supermarket) during which paranoia was assessed by the clinician. Qualitative interviews were performed with patients and the clinician performing the assessment to investigate experiences and feasibility. Further, measures of paranoia, social anxiety, and positive symptoms were obtained. Results Nine out of 10 participants with varying levels of paranoid ideation completed the assessment. Manifest inductive content analyses of the interviews revealed general experiences, advantages such as enabling observing participants from a different perspective, and challenges of the VR assessment, such as a lack of objectivity and the laboriousness of the assessment for the clinician. Although more paranoia was experienced during the supermarket scenario, correlates with classical measures were only significant for the bus scenario. Discussion The VR assessment was appreciated by most patients and the clinician. Based on our results short, standardized VR assessment scenarios are feasible, however, they do not appear reliable or objective for assessing paranoia. The clinical usefulness is most likely as a collaborative tool and add-on measure to existing methods.

Abstract
OBJECTIVES Auditory hallucinations (such as hearing voices) are common in clinical and non-clinical populations. Many people who hear voices also report early adversity and have an insecure attachment style. Current cognitive models suggest that dissociation mediates an association between disorganised attachment and auditory hallucinations, but this has not been tested experimentally. DESIGN We recruited a non-clinical analogue sample highly predisposed to auditory hallucinations and utilised an experimental design to examine the impact of disorganised attachment imagery on hallucinatory experiences, and whether dissociation mediates an expected association. METHODS Participants completed self-report measures of state auditory hallucinations and dissociation before and after random allocation to secure or disorganised attachment conditions. RESULTS Attachment imagery did not affect auditory hallucinations. Both secure and disorganised attachment conditions increased state dissociation. Secure attachment imagery reduced paranoia, but state dissociation did not mediate this effect. An exploratory analysis found that trait dissociation fully accounted for the association between trait-disorganised attachment and hallucinatory experience while controlling for paranoia. CONCLUSIONS Secure attachment imagery reduces paranoia but not auditory hallucinations and the impact on paranoia is not mediated by dissociation. Secure attachment imagery may be useful in reducing fears and distress associated with voices, rather than the frequency or severity of hallucinations. Disorganised attachment may increase hallucinatory experiences for people vulnerable to dissociation. Trait dissociation should be assessed in clinical settings and addressed where indicated as a means of targeting vulnerability to distressing voices.

Abstract
Introduction Childhood adversity is associated with the severity of multiple dimensions of psychosis, but the mechanisms underpinning the close link between the two constructs is unclear. Mentalization may underlie this relationship, as impaired mentalizing is found in various stages of the psychosis continuum. Nonetheless, the differential roles of self- and other-mentalizing in psychosis are not well understood. Methods Parallel multiple mediation was conducted for the relationship between a diverse range of childhood adversity types, including intentional and nonintentional harm, and schizotypy (positive, negative, disorganized), psychotic-like experiences (PLE) and paranoia via self-mentalizing (attention to emotions and emotional clarity) and other-mentalizing in n = 1,156 nonclinically ascertained young adults. Results Significant parallel multiple mediation models were found for all psychotic outcomes except negative schizotypy. The associations between intentionally harmful childhood adversity and psychotic outcomes were significantly mediated by increased attention to emotions for most models and decreased emotional clarity for some models. No significant mediation was found for parental loss. Paternal abuse was only mediated by attention to emotions whereas the effects of maternal abuse were mediated by attention to emotions and emotional clarity. Other-mentalizing only showed mediating effects on one of thirty models tested. Conclusion Results highlight the mediating role of impaired self-mentalizing in the association between childhood adversity and psychosis. This is consistent with disturbances of self-concept and self-boundary characterizing, in particular, the positive dimension of psychosis. Maternal versus paternal figures may contribute differentially to the development of mentalizing. These results could inform future preventative interventions, focusing on the development and maintenance of self-mentalizing.

Abstract
Recent diagnostic developments suggest that paranoia is a transdiagnostic characteristic common to several personality disorders rather than a personality disorder per se. Nonetheless, empirical literature fails to provide comprehensive and univocal findings on whether and how paranoid presentations relate to different personality disorders. In the present scoping review, we map the empirical literature on paranoid presentations in personality disorders, considering the entire spectrum of paranoid manifestations (i.e., the paranoia hierarchy). In selecting original quantitative studies on paranoid presentations in personality-disordered patients, we screened 4,433 records in PsycArticles, PsycInfo and PUBMED. We eventually included 47 eligible studies in the review. Our synthesis indicates consistent empirical evidence of a wide range of paranoid presentations in Paranoid, Schizotypal and Borderline personality disorders. Conversely, little empirical literature exists on paranoid presentations in other personality disorders. Preliminary findings suggest broad-severity paranoid presentations, ranging from milder to severe forms, in Paranoid, Schizotypal and Borderline personality disorders. There is also some evidence of milder forms of paranoia in Avoidant, Antisocial and Narcissistic personality disorders. Conversely, there is poor evidence of paranoid presentations in Schizoid, Histrionic, Dependent or Obsessive-compulsive personality disorders. Research gaps and recommendations for improving empirical research on paranoid presentations in personality disorders are discussed.

Abstract
Paranoia is common in clinical and nonclinical populations, consistent with continuum models of psychosis. A number of experimental studies have been conducted that attempt to induce, manipulate or measure paranoid thinking in both clinical and nonclinical populations, which is important to understand causal mechanisms and advance psychological interventions. Our aim was to conduct a systematic review and meta-analysis of experimental studies (non-sleep, non-drug paradigms) on psychometrically assessed paranoia in clinical and nonclinical populations. The review was conducted using PRISMA guidelines. Six databases (PsycINFO, PubMed, EMBASE, Web of Science, Medline and AMED) were searched for peer-reviewed experimental studies using within and between-subject designs to investigate paranoia in clinical and nonclinical populations. Effect sizes for each study were calculated using Hedge's g and were integrated using a random effect meta-analysis model. Thirty studies were included in the review (total n = 3898), which used 13 experimental paradigms to induce paranoia; 10 studies set out to explicitly induce paranoia, and 20 studies induced a range of other states. Effect sizes for individual studies ranged from 0.03 to 1.55. Meta-analysis found a significant summary effect of 0.51 [95% confidence interval 0.37-0.66, p < 0.001], indicating a medium effect of experimental paradigms on paranoia. Paranoia can be induced and investigated using a wide range of experimental paradigms, which can inform decision-making about which paradigms to use in future studies, and is consistent with cognitive, continuum and evolutionary models of paranoia.

Abstract
Introduction Although musical hallucinations do not tend to be accompanied by delusions, occasionally patients persistently accuse others of being responsible for causing the music they perceive, sometimes with severe social consequences such as frequently calling the police or moving house. In this study we seek to broaden our understanding of this rare type of musical hallucination that comes with secondary delusions and lack of insight, and to explore associations, underlying mechanisms, and treatment possibilities. Methods The present study is part of a cohort study on musical hallucinations carried out in the Netherlands from 2010 through 2023. Participants underwent testing with the aid of the MuHa Questionnaire, Launay-Slade Hallucinations Scale (LSHS), Schizotypal Personality Questionnaire (SPQ), Hamilton Depression Rating Scale (HDRS), and Mini Mental State Examination (MMSE). Additionally, they underwent a brain MRI, electroencephalogram, and audiological testing. Results Five patients out of a group of N = 81 (6%) lacked insight and presented with secondary delusions regarding the perceived music. They were all female, of advanced age, and hearing-impaired, and were diagnosed with cognitive impairment. In three patients (60%), risperidone was started. This had a positive effect on the hallucinations and secondary delusions. Conclusion The pathophysiological process underlying musical hallucinations is multifactorial in nature. We consider cognitive impairment the most likely contributing factor of the secondary delusions and lack of insight encountered in our patients, and antipsychotics the most beneficial treatment. On the basis of these small numbers, no definite conclusions can be drawn, so further research is needed to elucidate the underlying mechanisms and to develop evidence-based treatment methods for people experiencing this rare and debilitating combination of symptoms. Since the black box warning of risperidone cautions against the use of this drug in elderly persons with dementia, a proper comparison with the efficacy and safety of other antipsychotics for this group is paramount.

Abstract
BACKGROUND The term 'pandemic paranoia' has been coined to refer to heightened levels of mistrust and suspicion towards other people specifically due to the COVID-19 pandemic. In this study, we examine the international prevalence of pandemic paranoia in the general population and its associated sociodemographic profile. METHODS A representative international sample of general population adults (N = 2510) from five sites (USA N = 535, Germany N = 516, UK N = 512, Australia N = 502 and Hong Kong N = 445) were recruited using stratified quota sampling (for age, sex, educational attainment) and completed the Pandemic Paranoia Scale (PPS). RESULTS The overall prevalence rate of pandemic paranoia was 19%, and was highest in Australia and lowest in Germany. On the subscales of the PPS, prevalence was 11% for persecutory threat, 29% for paranoid conspiracy and 37% for interpersonal mistrust. Site and general paranoia significantly predicted pandemic paranoia. Sociodemographic variables (lower age, higher population size and income, being male, employed and no migrant status) explained additional variance and significantly improved prediction of pandemic paranoia. CONCLUSIONS Pandemic paranoia was relatively common in a representative sample of the general population across five international sites. Sociodemographic variables explained a small but significant amount of the variance in pandemic paranoia.

Abstract
INTRODUCTION There has been growing interest in the role of attachment mechanisms in the onset and maintenance of paranoia. The latest systematic reviews of mixed samples of healthy individuals and psychiatric patients have revealed that increased trait attachment anxiety and avoidance are associated with experiencing paranoia, with trait attachment anxiety showing a stronger association. Few studies have examined attachment and paranoia in naturalistic conditions via the Experience Sampling Method. OBJECTIVES The present study examined whether experiences of attachment anxiety and avoidance fluctuate in the flow of daily life, and whether a within-person change in both attachment states precedes the experience of momentary paranoia, and negative and positive emotions. METHODS Thirty-seven clinical participants and twenty-six healthy controls were studied over six consecutive days using the Experience Sampling Method (ESM). An experience-in-close-relationships questionnaire (ECR-R 16 SF) was used to capture trait attachment dimensions. Several ESM items were used to capture momentary negative and positive affect, paranoia and attachment insecurity states. RESULTS The findings revealed that fluctuations in both attachment insecurity states were significantly higher in the clinical group. A prior elevated attachment anxiety and avoidance was followed by an increase in negative affect in the next moment and elevated attachment avoidance was additionally followed by a decrease in positive affect and an increase in paranoia. CONCLUSION Our findings reveal the specific temporal associations between momentary attachment insecurity states as predictors of change in emotions/affects and paranoia, along with evidence that state attachment avoidance has a superior impact on momentary affect and paranoia compared to state attachment anxiety. These results contrast with those of recent cross-sectional studies.

Abstract
This case report provides a vivid illustration of a schizophrenic case in a 59-year-old man with auditory hallucinations, illuminating the nature of his symptoms. Auditory hallucinations were prominent, and the patient received voices urging him to perform actions that clearly corresponded to his paranoid thoughts. Through comprehensive research and long-term follow-up, this report reveals the complexity of traumatic schizophrenia, highlighting the importance of early recognition and intervention. One must emphasize a multidisciplinary approach, including psychiatric assessment, pharmacotherapy, and psychotherapy. This case report aims to highlight the critical role of comprehensive individual care in improving the patient's condition and emphasizes the importance of compassionate healthcare practices.

Abstract
Background This report presents the single case of Jack, a 67-year-old referred to our Older Adult Community Mental Health Team (OA CMHT) for his distressing persecutory delusion and high levels of worry. Jack also reported learning difficulties and autistic traits, although neither were formally diagnosed. Method Ten sessions of worry intervention taken from The Feeling Safe Programme worry module were used to reduce Jack's time spent worrying and increase his engagement in meaningful activity. Weekly face-to-face sessions were held, with Jack's brother acting as a co-therapist. Adaptations to the intervention were made based on Jack's learning preferences. An AB single case experimental design was adopted to compare Jack's scores on measures of worry, paranoia and delusional conviction, and wellbeing and daily functioning before and after intervention. Results Results demonstrate the worry intervention improved Jack's scores on all measures to a clinically significant degree. Conclusions This is the first known report of applying the worry intervention to an older adult. The results show the intervention can be of considerable benefit in terms of reducing worry and paranoia, in the context of both older age and suspected neurodiversity.

Abstract
BACKGROUND Paranoia is higher in minority group individuals, especially those reporting intersecting aspects of difference. High negative and low positive self and other beliefs, and low social rank, are predictive of paranoia overtime; however, data are typically from majority group participants. This study examined whether social defeat or healthy cultural mistrust best characterizes paranoia in minority groups. STUDY DESIGN Using cross-sectional, survey design, with a large (n = 2510) international sample, moderation analyses (PROCESS) examined whether self and other beliefs, and perceived social rank, operate similarly or differently in minority vs majority group participants. Specifically, we tested whether beliefs moderated the influence of minority group, and intersecting aspects of difference, on paranoia. STUDY RESULTS Paranoia was consistently higher in participants from minority vs majority groups and level of paranoid thinking was significantly higher at each level of the intersectionality index. Negative self/other beliefs were associated with elevated paranoia in all participants. However, in support of the notion of healthy cultural mistrust, low social rank, and low positive self/other beliefs were significantly associated with paranoia in majority group participants but unrelated to paranoia in respective minority group members. CONCLUSIONS Although mixed, our findings signal the need to consider healthy cultural mistrust when examining paranoia in minority groups and bring into question whether "paranoia" accurately describes the experiences of marginalized individuals, at least at low levels of severity. Further research on paranoia in minority groups is crucial to developing culturally appropriate ways of understanding people's experiences in the context of victimization, discrimination, and difference.

Abstract
BACKGROUND AND HYPOTHESIS Game theory paradigms, such as the Prisoner's Dilemma Game (PDG), have been used to study nonclinical paranoia, though research using clinical populations has been scarce. We test our novel theoretical model that schizophrenia leads to competitiveness in interpersonal interactions, and that this link is serially mediated by trait paranoia, state paranoia, and distrust. STUDY DESIGN In this quasi-experimental study, individuals with schizophrenia spectrum diagnoses with current persecutory delusions (n = 46) and a nonclinical control group (n = 43) played the PDG, and completed measures of trait paranoia, state paranoia, and distrust. STUDY RESULTS Individuals with schizophrenia competed more in the PDG than the control group. Supporting our theoretical model, all direct effects were significant: schizophrenia was associated with higher trait paranoia (H1); trait paranoia predicted state paranoia in the PDG (H2); state paranoia in the PDG predicted distrust of the opponent in the PDG (H3); and distrust predicted competition in the PDG (H4). The hypothesized indirect effect of schizophrenia on competition in the PDG via trait paranoia, state paranoia, and distrust was supported in a serial mediation model (H5). CONCLUSIONS The findings make clear theoretical and methodological contributions. We provide the first evidence for a theoretical process model by which schizophrenia leads to competitiveness in interpersonal interactions via trait paranoia, state paranoia, and distrust. Game theory paradigms, and the PDG in particular, are important for advancing theory and research on paranoia as it occurs in both clinical and nonclinical populations.

Abstract
Since the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic was declared, cases of psychosis, delusions, hallucinations, and disorganized behavior have been reported worldwide, both during the acute phase of COVID-19 and after recovery. Given the recent emergence of COVID-19, data are still accumulating, and it is premature to correlate COVID-19 with psychotic disorders causally. However, SARS-CoV-2 has been shown to have the ability to cross the blood-brain barrier and penetrate neurons. This finding and the amount of published work on COVID-19 and psychotic disorders compel special attention to elucidate the link between SARS-CoV-2 and the occurrence of psychotic symptoms. In this article, several reviews and case reports that have analyzed the link between COVID-19 and psychotic disorders are reviewed. In light of the data that have emerged at the present time, study criteria were proposed to identify COVID-19-related psychosis.

Abstract
BACKGROUND Cognitive Bias Modification for paranoia (CBM-pa) is a novel, theory-driven psychological intervention targeting the biased interpretation of emotional ambiguity associated with paranoia. Study objectives were (i) test the intervention's feasibility, (ii) provide effect size estimates, (iii) assess dose-response and (iv) select primary outcomes for future trials. METHODS In a double-blind randomised controlled trial, sixty-three outpatients with clinically significant paranoia were randomised to either CBM-pa or an active control (text reading) between April 2016 and September 2017. Patients received one 40 min session per week for 6 weeks. Assessments were given at baseline, after each interim session, post-treatment, and at 1- and 3-months post-treatment. RESULTS A total of 122 patients were screened and 63 were randomised. The recruitment rate was 51.2%, with few dropouts (four out of 63) and follow-up rates were 90.5% (1-month) and 93.7% (3-months). Each session took 30-40 min to complete. There was no statistical evidence of harmful effects of the intervention. Preliminary data were consistent with efficacy of CBM-pa over text-reading control: patients randomised to the intervention, compared to control patients, reported reduced interpretation bias (d = -0.48 to -0.76), improved symptoms of paranoia (d = -0.19 to -0.38), and lower depressed and anxious mood (d = -0.03 to -0.29). The intervention effect was evident after the third session. CONCLUSIONS CBM-pa is feasible for patients with paranoia. A fully powered randomised control trial is warranted.

Abstract
Aims Given the risk of developing vicarious trauma through news media has increased during the pandemic, we explored risk factors associated with media induced secondary trauma, and its behavioral and psychological implications. Methods An international study (N = 1066), with a diverse sample, was administered in July 2020. We used standardized and validated questionnaires to measure news consumption, media-related trauma, compliance, and paranoia. Results Greater frequency of news consumption, accessing news via social media and WHO, and believing in conspiracy theories increased likelihood of developing media-induced secondary trauma. News related trauma was associated with greater compliance with safety measures and increased paranoid ideation. Media-trauma however exhibited a greater association with paranoia than compliance. Conclusion Findings highlight the need to facilitate a collaborative intervention, with public, media houses, health safety officials, and social scientists to have a deeper understanding of potential psychological costs of news consumption patterns.

Abstract
BACKGROUND Persecutory fears build on feelings of vulnerability that arise from negative views of the self. Body image concerns have the potential to be a powerful driver of feelings of vulnerability. Body image concerns are likely raised in patients with psychosis given the frequent weight gain. We examined for the first-time body esteem - the self-evaluation of appearance - in relation to symptom and psychological correlates in patients with current persecutory delusions. METHODS One-hundred and fifteen patients with persecutory delusions in the context of non-affective psychosis completed assessments of body image, self-esteem, body mass index (BMI), psychiatric symptoms and well-being. Body esteem was also assessed in 200 individuals from the general population. RESULTS Levels of body esteem were much lower in patients with psychosis than non-clinical controls (d = 1.2, p < 0.001). In patients, body esteem was lower in women than men, and in the overweight or obese BMI categories than the normal weight range. Body image concerns were associated with higher levels of depression (r = -0.55, p < 0.001), negative self-beliefs (r = -0.52, p < 0.001), paranoia (r = -0.25, p = 0.006) and hallucinations (r = -0.21, p = 0.025). Body image concerns were associated with lower levels of psychological wellbeing (r = 0.41, p < 0.001), positive self-beliefs (r = 0.40, p < 0.001), quality of life (r = 0.23, p = 0.015) and overall health (r = 0.31, p = 0.001). CONCLUSIONS Patients with current persecutory delusions have low body esteem. Body image concerns are associated with poorer physical and mental health, including more severe psychotic experiences. Improving body image for patients with psychosis is a plausible target of intervention, with the potential to result in a wide range of benefits.

Abstract
BACKGROUND Previous research has shown a link between childhood sexual abuse (CSA) and more severe symptoms of psychosis. There is also evidence that self-compassion is a key mechanism linking adverse childhood experiences and mental health problems such as post-traumatic stress disorder and depression, but no research has examined these links in psychosis. METHODS We analysed existing cross-sectional data, including 55 individuals with psychosis and 166 individuals from the general population. Participants completed standardized measures of CSA, self-compassion, paranoia, positive psychotic symptoms and distress linked to psychosis. RESULTS The clinical group had higher scores on CSA and all psychosis measures, but we found no differences in self-compassion between the groups. Higher levels of CSA correlated with lower self-compassion and higher paranoia and positive symptoms in both groups. CSA also correlated with distress linked to psychosis in the non-clinical group. Lower self-compassion mediated the association between higher levels of CSA and more severe paranoia in both groups. In the non-clinical group, lower self-compassion also mediated the association between greater CSA and more positive psychotic symptoms and more severe distress. CONCLUSIONS This is the first study to show that self-compassion mediates the link between CSA and both paranoia and psychotic symptoms in adulthood. Self-compassion may therefore be an important transdiagnostic candidate target in therapy to mitigate the impact of early adversity on paranoia in both clinical and non-clinical groups. Limitations include the small clinical sample and inclusion of a cannabis-using non-clinical sample, though recent cannabis use did not impact self-compassion levels.

Abstract
INTRODUCTION Paranoia is a common and impairing psychosis symptom, which exists along a severity continuum that extends into the general population. Individuals at clinical high-risk for psychosis (CHR) frequently experience paranoia and this may elevate their risk for developing full psychosis. Nonetheless, limited work has examined the efficient measurement of paranoia in CHR individuals. The present study aimed to validate an often-used self-report measure, the revised green paranoid thoughts scale (RGPTS), in this critical population. METHOD Participants were CHR individuals (n = 103), mixed clinical controls (n = 80), and healthy controls (n = 71) who completed self-report and interview measures. Confirmatory factor analysis (CFA), psychometric indices, group differences, and relations to external measures were used to evaluate the reliability and validity of the RGPTS. RESULTS CFA replicated a two-factor structure for the RGPTS and the associated reference and persecution scales were reliable. CHR individuals scored significantly higher on both reference and persecution, relative to both healthy (ds = 1.03, 0.86) and clinical controls (ds = 0.64, 0.73). In CHR participants, correlations between reference and persecution and external measures were smaller than expected, though showed evidence of discriminant validity (e.g., interviewer-rated paranoia, r = 0.24). When examined in the full sample, correlation magnitude was larger and follow-up analyses indicated that reference related most specifically to paranoia (β = 0.32), whereas persecution uniquely related to poor social functioning (β = -0.29). CONCLUSION These results demonstrate the reliability and validity of the RGPTS, though its scales related more weakly to severity in CHR individuals. The RGPTS may be useful in future work aiming to develop symptom-specific models of emerging paranoia in CHR individuals.

Abstract
BACKGROUND Globally, the corona virus disease 2019 (COVID-19) pandemic has created an interpersonally threatening context within which other people have become a source of possible threat. This study reports on the development and validation of a self-report measure of pandemic paranoia; that is, heightened levels of suspicion and mistrust towards others due to the COVID-19 pandemic. METHODS An international consortium developed an initial set of 28 items for the Pandemic Paranoia Scale (PPS), which were completed by participants from the UK (n = 512), USA (n = 535), Germany (n = 516), Hong Kong (n = 454) and Australia (n = 502) using stratified quota sampling (for age, sex and educational attainment) through Qualtrics and translated for Germany and Hong Kong. RESULTS Exploratory factor analysis in the UK sample suggested a 25-item, three-factor solution (persecutory threat; paranoid conspiracy and interpersonal mistrust). Confirmatory factor analysis (CFA) on the remaining combined sample showed sufficient model fit in this independent set of data. Measurement invariance analyses suggested configural and metric invariance, but no scalar invariance across cultures/languages. A second-order factor CFA on the whole sample indicated that the three factors showed large loadings on a common second-order pandemic paranoia factor. Analyses also supported the test-retest reliability and internal and convergent validity. CONCLUSION The PPS offers an internationally validated and reliable method for assessing paranoia in the context of a pandemic. The PPS has the potential to enhance our understanding of the impact of the pandemic, the nature of paranoia and to assist in identifying and supporting people affected by pandemic-specific paranoia.

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 The Feeling Safe Programme is a cognitive therapy developed to improve outcomes for individuals with persecutory delusions. It is theoretically driven, modular and personalised, with differences in therapeutic style and content compared with first-generation cognitive behavioural therapy for psychosis. OBJECTIVES We set out to understand the participant experience of the Feeling Safe Programme. DESIGN A qualitative study employing interpretative phenomenological analysis. METHODS Using a peer research approach, semi-structured face-to-face interviews were conducted with six people who had received the Feeling Safe Programme as part of the outcome clinical trial. RESULTS Participants spoke of feeling 'unsafe' in their daily lives before the intervention. Openness to the intervention, facilitated by identification with the programme name, and willingness to take an active role were considered important participant attributes for successful outcomes. The therapist was viewed as a professional friend who cared about the individual, which enabled trust to form and the opportunity to consider new knowledge and alternative perspectives. Doing difficult tasks gradually and repeatedly to become comfortable with them was important for change to occur. The intervention helped people to do ordinary things that others take for granted and was perceived to produce lasting changes. CONCLUSIONS The Feeling Safe Programme was subjectively experienced very positively by interview participants, which is consistent with the results of the clinical trial. The successful interaction of the participant and therapist enabled trust to form, which meant that repeated practice of difficult tasks could lead to re-engagement with valued everyday activities.

Abstract
New-onset psychotic symptoms presenting late in life can be caused by various medical and psychiatric conditions. The index of suspicion for an organic cause for psychotic symptoms in an elderly person should be high, and every presenting patient should undergo a detailed history-taking and evaluation before attributing these symptoms to a primary psychiatric condition. Hyperparathyroidism is one condition that can present with psychiatric symptoms such as low mood and anxiety. While psychiatric symptoms are not uncommon in hyperparathyroidism, acute psychosis is rare. This case report highlights the importance of a thorough evaluation of an elderly person presenting with a new onset of psychosis.

Abstract
The 2019 coronavirus (Covid-19) pandemic has impacted people's mental wellbeing. Studies to date have examined the prevalence of mental health symptoms (anxiety and depression), yet fewer longitudinal studies have compared across background factors and other psychological variables to identify vulnerable subgroups in the general population. This study tests to what extent higher levels of schizotypal traits and paranoia are associated with mental health variables 6- and 12-months since April 2020. Over 2300 adult volunteers (18-89 years, female = 74.9%) with access to the study link online were recruited from the UK, the USA, Greece and Italy. Self-reported levels of schizotypy, paranoia, anxiety, depression, aggression, loneliness and stress from three timepoints (17 April to 13 July 2020, N1 = 1599; 17 October to 31 January 2021, N2 = 774; and 17 April to 31 July 2021, N3 = 586) were mapped using network analysis and compared across time and background variables (sex, age, income, country). Schizotypal traits and paranoia were positively associated with poorer mental health through loneliness, with no effect of age, sex, income levels, countries and timepoints. Loneliness was the most influential variable across all networks, despite overall reductions in levels of loneliness, schizotypy, paranoia and aggression during the easing of lockdown (time 3). Individuals with higher levels of schizotypal traits/paranoia reported poorer mental health outcomes than individuals in the low-trait groups. Schizotypal traits and paranoia are associated with poor mental health outcomes through self-perceived feelings of loneliness, suggesting that increasing social/community cohesion may improve individuals' mental wellbeing in the long run.

Abstract
OBJECTIVES This study aimed to investigate associations between proximity seeking, stress and paranoia in the context of daily life, and whether these relationships are moderated by trait attachment styles. METHODS Sixty non-clinical participants completed 3423 assessments of state stress, proximity seeking and paranoia over a 6-day period using an experience sampling method. Multilevel linear regression was performed to evaluate relationships between variables. RESULTS The post-hoc analysis showed antecedent events subjectively appraised as very unpleasant or very pleasant predicted greater levels of momentary proximity seeking at the subsequent timepoint. Greater stress predicted greater subsequent shifts or variability in proximity seeking. Changes in proximity seeking were not associated with momentary paranoia. However, for individuals with an avoidant attachment style, greater shifts in proximity seeking resulted in greater subsequent reports of paranoia. CONCLUSIONS These findings suggest that, in daily life, the attachment system may become active in response to stress. For those with an avoidant attachment style, an active attachment system may exacerbate paranoid thoughts possibly due to the activation of attachment-related beliefs that one should be fearful of unavailable others and instead rely on one's autonomy to regulate affect. These findings highlight the need to consider attachment in the assessment and formulation of paranoia.

Abstract
ABSTRACT Individuals belonging to ethnic minority groups are less likely to experience symptoms of psychosis, such as paranoia, if they live in areas with high proportions of people from the same ethnic background. This effect may be due to processes associated with group belonging (social identification). We examined whether the relationship between perceived discrimination and paranoia was moderated by explicit and implicit Pakistani/English identification among students of Pakistani heritage (N = 119). Participants completed measures of explicit and implicit Pakistani and English identity, a measure of perceived discrimination, and a measure of paranoia. Perceived discrimination was the strongest predictor of paranoia (0.31). Implicit identities moderated the relationship between perceived discrimination and paranoia (-0.17). The findings suggest that higher levels of implicit Pakistani identity were most protective against high levels of paranoia (0.26, with low implicit English identity; 0.78, with medium English identity; 1.46, with high English identity). Overall, a complex relationship between identity and paranoia was apparent.

Abstract
OBJECTIVES SlowMo is the first blended digital therapy for paranoia, showing significant small-moderate reductions in paranoia in a recent large-scale randomized controlled trial (RCT). This study explored the subjective service-user experience of the SlowMo therapy content and design; the experience of the blended therapy approach, including the triangle of the therapeutic alliance; and the experience of the digital aspects of the intervention. DESIGN Qualitative co-produced sub-study of an RCT. METHODS Participants were 22 adult service users with schizophrenia-spectrum psychosis and persistent distressing paranoia, who completed at least one SlowMo therapy session and a 24-week follow-up, at one of 3 sites in Oxford, London, and Sussex, UK. They were interviewed by peer researchers, using a topic guide co-produced by the Patient and Public Involvement (PPI) team. The transcribed data were analysed thematically. Multiple coding and triangulation, and lay peer researcher validation were used to reach a consensus on the final theme structure. RESULTS Six core themes were identified: (i) starting the SlowMo journey; (ii) the central role of the supportive therapist; (iii) slowing things down; (iv) value and learning from social connections; (v) approaches and challenges of technology; and (vi) improvements in paranoia and well-being. CONCLUSIONS For these service users, slowing down for a moment was helpful, and integrated into thinking over time. Learning from social connections reflected reduced isolation, and enhanced learning through videos, vignettes, and peers. The central role of the supportive therapist and the triangle of alliance between service user, therapist, and digital platform were effective in promoting positive therapeutic outcomes.

Abstract
OBJECTIVES Paranoia describes unfounded interpersonal threat beliefs. Secure attachment imagery attenuates paranoia, but limited research examines mechanisms of change and no studies examine how secure imagery may be implemented most effectively in clinical practice. In this study, we tested: (a) the causal impact of secure, anxious, and avoidant attachment imagery on paranoia and anxiety, (b) whether emotion regulation strategies mediate these relationships, and (c) whether secure imagery buffers against social stress. DESIGN We utilized a longitudinal, experimental design. METHOD A general population sample with high non-clinical paranoia (N = 265) completed measures of paranoia, anxiety, and emotion regulation strategies. Participants were randomly allocated to secure, anxious, or avoidant conditions and repeated an imagery prime for four days prior to a social stress task. RESULTS Relative to anxious and avoidant imagery, secure imagery decreased state paranoia and anxiety. These associations were not mediated by state emotion regulation strategies, and secure imagery did not buffer against stress. Exploratory analyses on trait variables revealed that: (a) hyperactivating strategies mediated the association between attachment anxiety and paranoia, and (b) suppression mediated the association between attachment avoidance and paranoia. CONCLUSIONS Secure attachment imagery reduces state paranoia and anxiety and could be incorporated into psychotherapies to attenuate clinical paranoia. Measurement of state emotion regulation was problematic. Attachment imagery does not buffer stress; further research is required to test whether secure imagery facilitates recovery from stress. Attachment style is likely to account for trait paranoia via attachment-congruent emotion regulation strategies. Research is now needed to determine if these strategies can be targeted to alleviate paranoia in clinical populations.

Abstract
BACKGROUND AND HYPOTHESIS Despite decades of "proof of concept" findings supporting the use of Natural Language Processing (NLP) in psychosis research, clinical implementation has been slow. One obstacle reflects the lack of comprehensive psychometric evaluation of these measures. There is overwhelming evidence that criterion and content validity can be achieved for many purposes, particularly using machine learning procedures. However, there has been very little evaluation of test-retest reliability, divergent validity (sufficient to address concerns of a "generalized deficit"), and potential biases from demographics and other individual differences. STUDY DESIGN This article highlights these concerns in development of an NLP measure for tracking clinically rated paranoia from video "selfies" recorded from smartphone devices. Patients with schizophrenia or bipolar disorder were recruited and tracked over a week-long epoch. A small NLP-based feature set from 499 language samples were modeled on clinically rated paranoia using regularized regression. STUDY RESULTS While test-retest reliability was high, criterion, and convergent/divergent validity were only achieved when considering moderating variables, notably whether a patient was away from home, around strangers, or alone at the time of the recording. Moreover, there were systematic racial and sex biases in the model, in part, reflecting whether patients submitted videos when they were away from home, around strangers, or alone. CONCLUSIONS Advancing NLP measures for psychosis will require deliberate consideration of test-retest reliability, divergent validity, systematic biases and the potential role of moderators. In our example, a comprehensive psychometric evaluation revealed clear strengths and weaknesses that can be systematically addressed in future research.

Abstract
OBJECTIVE To test a novel proposition that dispositional forgiveness has the unrecognised benefit of buffering feelings of paranoia following negative interpersonal experiences and interpersonal transgressions. METHODS In Study 1 (N = 128), we used an experimental paradigm, the Prisoner's Dilemma Game (PDG), to test the premise that an interpersonal transgression increases state paranoia. Study 2 (N = 180) used a longitudinal design to test the central proposition that dispositional forgiveness buffers state paranoia following naturally occurring difficult (vs pleasant) interpersonal events. Study 3 (N = 102) used a novel experimental paradigm to determine the causal effect of manipulating forgiveness on paranoia. RESULTS In Study 1, interpersonal transgressions in the PDG increased paranoia. In Study 2, paranoia was higher following difficult (rather than pleasant) events, and higher levels of dispositional forgiveness moderated the negative effect of difficult events on paranoia. In Study 3, there was a causal effect of forgiveness on (reduced) paranoia. CONCLUSIONS This is the first evidence that (1) interpersonal transgressions increase paranoia, (2) high dispositional forgiveness moderates the deleterious effect of interpersonal transgression on paranoia, and (3) dispositional forgiveness is causally related to less paranoia.

Abstract
Paranoia and suicidality seem to be common traits expressing in the general population to varying degrees. This study aims to explore the association between both and to identify determinants of comorbidity. We interviewed a representative sample of the population in Andalusia (n = 4507) and assessed paranoia and suicidality utilizing the Spanish Green's Paranoid Thoughts Scale (S-GPTS) and the suicidality section of the MINI Neuropsychiatric Interview, respectively. We gathered data on socio-demographics, personality, substance abuse, social support, and environmental distress. We found that paranoia and suicidality were rather common with 6.4% (95% CI: 5.7-7.12) of the sample admitting to some (vs. none) level of suicidality. We also found a robust association between paranoia and suicidality, independent of age and sex (F:298.2; p =.0001; Eta2: .065); 0.5% (95% CI: 0.32-0.76) of the sample (n = 21) presented combinedly high levels of paranoia and some suicidality risk and were considered as having paranoia-suicidality comorbidity (PSC). We identified factors associating with PSC, including poor social support, childhood maltreatment, threatening life-events and increasing personality disorder, and nicotine dependence scores. Paranoia and suicidality are common traits in the general population and their comorbidity seems to associate with low social support, environmental adversity and disordered personality. Suicidality and paranoia are common traits present dimensionally in a representative nonclinical sample. Paranoia strongly and independently associates with suicidality risk in a large population-based study. Paranoia and suicidality comorbidity may be commonly determined by poor social support, disordered personality, previous childhood maltreatment, and exposure to threatening life-events.

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
OBJECTIVES SlowMo therapy is a pioneering blended digital therapy for paranoia, augmenting face-to-face therapy with an interactive 'webapp' and a mobile app. A recent large-scale trial demonstrated small-moderate effects on paranoia alongside improvements in self-esteem, worry, well-being and quality of life. This paper provides a comprehensive account of therapy personalisation within this targeted approach. DESIGN Case examples illustrate therapy delivery and descriptive data are presented on personalised thought content. METHOD Thought content was extracted from the webapp (n = 140 participants) and coded using newly devised categories: Worries: (1) Persecutory, (2) Negative social evaluation, (3) Negative self-concept, (4) Loss/life stresses, (5) Sensory-perceptual experiences and (6) Health anxieties. Safer thoughts: (1) Safer alternative (specific alternatives to worries), (2) Second-wave (generalised) coping, (3) Positive self-concept, (4) Positive activities and (5) Third-wave (mindfulness-based) coping. Data on therapy fidelity are also presented. RESULTS Worries: 'Persecutory' (92.9% of people) and 'Negative social evaluation' (74.3%) were most common. 'General worries/ life stresses' (31.4%) and 'Negative self-concept' (22.1%) were present in a significant minority; 'Health anxieties' (10%) and 'Sensory-perceptual' (10%) were less common. Safer thoughts: 'Second-wave (general) coping' (85%), 'Safer alternatives' (76.4%), 'Positive self-concept' (65.7%) and 'Positive activities' (64.3%) were common with 'Third-wave' (mindfulness) coping observed for 30%. Fidelity: Only three therapy withdrawals were therapy related. Session adherence was excellent (mean = 15.2/16; SD = 0.9). Behavioural work was conducted with 71% of people (119/168). CONCLUSION SlowMo therapy delivers a targeted yet personalised approach. Potential mechanisms of action extend beyond reasoning. Implications for cognitive models of paranoia and causal interventionist approaches are discussed.

Abstract
Gustav Specht (1860-1940) developed academic psychiatry in Erlangen. After studying medicine in Würzburg, Munich and Berlin, he became assistant medical director in the mental asylum of Erlangen. In 1897 he was appointed extraordinary, and in 1903 ordinary, Professor of Psychiatry. A good clinician and teacher, Specht worked during a time of paradigm change in psychiatry. He was an expert in chronic mania, and introduced the concept of the 'grumbler's delusion'. Paranoia he believed to be the core problem of psychopathology and considered the depressive syndrome as an 'exogenous-type' of reaction. For him, trauma was important in the genesis of mental illness, and his 'hystero-melancholy' anticipated the concept of borderline personality disorder.

Abstract
Serious mental illness is associated with a higher risk of violent interpersonal behavior. Characteristic traits denoting a psychopatho-logical picture such as schizophrenia, depression, a borderline, or narcissistic, antisocial, or paranoid personality disorder, are frequently observed in the personality of those who have committed one or more murders. For example, mass murderers are affected by a delusional syndrome with a persecution fixation, that develops in a subject with a paranoid, anacastic personality disorder. An abnormal mental frame-work develops as a consequence of continual experiences interpreted as traumatic. We present a complex case regarding a double murder whose vic-tims were shot by a 50-year-old neighbor, who underwent a psychiatric evaluation for the assessment of criminal responsibility. In the light of the historical reconstruction of his relation sensitive delusional mindset that triggered the final reaction, his life history, the "key event" and the "triggering environment" (constant conflictual and dysfunctional rela-tions with others) led to the violence. The correct understanding of the reported case demands investigation not only of the clinical, diagnostic and psychodiagnostic aspects, but also of the perpetrator-victim/s, their relational context and the situation where the crime evolves, in order to be able to reconstruct the event in a meaningful manner.

Abstract
Paranoia is a clinical and cultural phenomenon of the 21st century. From a Jungian lens, paranoia is thought of in two fundamental ways: as a disorder of meaning rooted in the Self, and the insanity of literalism where metaphor is absent. Paranoia, in our current 'civilization in transition', takes the form of a 'tyranny of unification or the curse of the One' promulgated by waves of fear, panic, horror and exclusion towards everything that differs from the supposedly instituted order. As a single fundamentalist truth, paranoia takes root in the public field of politics where self-exhibitionism feeds the delusional paranoid logic that degrades both the personal and collective fabrics. Jungian psychology offers an antidote to paranoia by cultivating and respecting democratic spaces both analytically and in the collective.

Abstract
Background Paranoia is associated with a multitude of social cognitive deficits, observed in both clinical and subclinical populations. Empathy is significantly and broadly impaired in schizophrenia, yet its relationship with subclinical paranoia is poorly understood. Furthermore, deficits in emotion recognition - a very early component of empathic processing - are present in both clinical and subclinical paranoia. Deficits in emotion recognition may therefore underlie relationships between paranoia and empathic processing. The current investigation aims to add to the literature on social cognition and paranoia by: (1) characterizing the relationship between paranoia and empathy, and (2) testing whether there is an indirect effect of emotion recognition on the relationship between empathy and paranoia. Methods Paranoia, empathy, and emotion recognition were assessed in a non-clinical sample of adults (n = 226) from the Nathan Kline Institute-Rockland (NKI-Rockland) dataset. Paranoia was measured using the Peters Delusions Inventory-21 (PDI-21). Empathy was measured using the Interpersonal Reactivity Index (IRI), a self-report instrument designed to assess empathy using four subscales: Personal Distress, Empathic Concern, Perspective Taking, and Fantasy. Emotion recognition was assessed using the Penn Emotion Recognition Test (ER-40). Structural equation modeling (SEM) was used to estimate relationships between paranoia, the four measures of empathy and emotion recognition. Results Paranoia was associated with the Fantasy subscale of the IRI, such that higher Fantasy was associated with more severe paranoia (p < 0.001). No other empathy subscales were associated with paranoia. Fantasy was also associated with the emotion recognition of fear, such that higher Fantasy was correlated with better recognition of fear (p = 0.008). Paranoia and emotion recognition were not significantly associated. The Empathic Concern subscale was negatively associated with emotion recognition, with higher empathic concern related to worse overall emotion recognition (p = 0.002). All indirect paths through emotion recognition were non-significant. Discussion These results suggest that imaginative perspective-taking contributes to paranoia in the general population. These data do not, however, point to robust global relationships between empathy and paranoia or to emotion recognition as an underlying mechanism. Deficits in empathy and emotion recognition observed in schizophrenia may be associated with the broader pathology of schizophrenia, and therefore not detectable with subclinical populations.

Abstract
BACKGROUND Functional recovery in psychosis remains a challenge despite current evidence-based treatment approaches. To address this problem, innovative interventions using virtual reality (VR) have recently been developed. VR technologies have enabled the development of realistic environments in which individuals with psychosis can receive psychosocial treatment interventions in more ecological settings than traditional clinics. These interventions may therefore increase the transfer of learned psychosocial skills to real-world environments, thereby promoting long-term functional recovery. However, the overall feasibility and efficacy of such interventions within the psychosis population remain unclear. OBJECTIVE This systematic review aims to investigate whether VR-based psychosocial interventions are feasible and enjoyable for individuals with psychosis, synthesize current evidence on the efficacy of VR-based psychosocial interventions for psychosis, and identify the limitations in the current literature to guide future research. METHODS This research followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Literature searches were conducted in PubMed and PsycINFO in May 2021. We searched for peer-reviewed English articles that used a psychosocial intervention with a VR component. Participants in the included studies were diagnosed with schizophrenia, schizoaffective disorder, or another psychotic disorder. The included studies were divided into four categories as follows: cognitive remediation interventions, social skills interventions, vocational skills interventions, and auditory verbal hallucinations and paranoia interventions. The risk of bias assessment was performed for each study. RESULTS A total of 18 studies were included in this systematic review. Of these 18 studies, 4 (22%) studies used a cognitive remediation intervention, 4 (22%) studies used a social skills intervention, 3 (17%) studies used a vocational skills intervention, and 7 (39%) studies implemented an intervention aimed at improving auditory verbal hallucinations or paranoia. A total of 745 individuals with psychosis were included in the study. All the studies that evaluated feasibility showed that VR-based psychosocial interventions were feasible and enjoyable for individuals with psychosis. The preliminary evidence on efficacy included in this review suggests that VR-based psychosocial interventions can improve cognitive, social, and vocational skills in individuals with psychosis. VR-based interventions may also improve the symptoms of auditory verbal hallucinations and paranoia. The skills that participants learned through these interventions were durable, transferred into real-world environments, and led to improved functional outcomes, such as autonomy, managing housework, and work performance. CONCLUSIONS VR-based interventions may represent a novel and efficacious approach for improving psychosocial functioning in psychosis. Therefore, VR-based psychosocial interventions represent a promising adjunctive therapy for the treatment of psychosis, which may be used to improve psychosocial skills, community functioning, and quality of life.
