BRITISH JOURNAL OF CLINICAL PSYCHOLOGY 2024. [PMID: 39233367 DOI: 10.1111/bjc.12496] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Accepted: 07/23/2024] [Indexed: 09/06/2024]
Abstract
OBJECTIVES Psychosis can be thought of as a threat-based experience. Compassion has been shown to be effective in reducing threat, although highly distressed individuals may struggle to be self-compassionate. This study explored the effects of compassionate interactions with staff on inpatients with psychosis. METHOD Experience Sampling Method (ESM) was used to investigate the relationships between compassion from staff and paranoia, voice hearing, distress related to psychosis experiences, affect and risk incidents in daily life. Twenty-two service users residing on inpatient mental health wards took part. Baseline measures of compassion, fears of compassion and affect were taken. Participants completed ESM assessments 10 times per day, over 6 days. RESULTS Compassion from staff was associated with a small increase in voice hearing, but was not associated with paranoia, paranoia-related distress, voice-related distress, negative affect, positive affect, or risk incidents in daily life. Baseline fears of compassion moderated the relationships between compassion from staff and some of the service user outcomes. For inpatients scoring low on fears of compassion, compassionate interactions were associated with increased positive affect and lower paranoia. However, for those scoring high on fears of compassion, this relationship was reversed, and compassionate interactions were associated with higher paranoia and lower positive affect. CONCLUSION People with psychosis who have fears of compassion may benefit from receiving support to address these fears in order to experience the benefit from the compassion of staff. The results should be interpreted with caution due to the low number of observations and limited statistical power.

Abstract
BACKGROUND Paranoia is a key feature of psychosis that can be highly debilitating. Theories of paranoia mostly interface with short-scale or cross-sectional data models, leaving the longitudinal course of paranoia underspecified. METHODS We develop an empirical characterisation of two aspects of paranoia - persecutory and referential delusions - in individuals with psychosis over 20 years. We examine delusional dynamics by applying a Graphical Vector Autoregression Model to data collected from the Chicago Follow-up Study (n = 135 with a range of psychosis-spectrum diagnoses). We adjusted for age, sex, IQ, and antipsychotic use. RESULTS We found that referential and persecutory delusions are central themes, supported by other primary delusions, and are strongly autoregressive - the presence of referential and persecutory delusions is predictive of their future occurrence. In a second analysis we demonstrate that social factors influence the severity of referential, but not persecutory, delusions. IMPLICATIONS We suggest that persecutory delusions represent central, resistant states in the cognitive landscape, whereas referential beliefs are more flexible, offering an important window of opportunity for intervention. Our data models can be collated with prior biological, computational, and social work to contribute toward a more complete theory of paranoia and provide more time-dependent evidence for optimal treatment targets.

Abstract
We investigated the associations between daily stress, sexual desire and intimacy in gay men in long-term relationships. A daily diary method of data collection was used. Twenty-two adult participants completed brief questionnaires ten times per day during seven consecutive days. Multilevel regression analyses revealed significant negative associations of daily stress with sexual desire (p = 0.003); higher stress came with lower levels of sexual desire, and vice versa. The hypothesized moderation effect of the associations of stress with sexual desire by intimacy was found significant (p = 0.003). However, the effect was not as predicted: at higher levels of intimacy the negative effect of stress on sexual desire was shown to be stronger than at lower levels. Most temporal associations of stress and intimacy with sexual desire were not significant. Nevertheless, the present findings implicate that daily stress and intimacy are important factors in sexual functioning of gay men in long-term relationships.

Abstract
Previous cross-sectional and laboratory research has identified risk factors for persecutory ideation including rumination, negative affect, and safety-seeking behaviors. Questions remain about what in-the-moment factors link general negative affect to PI as well as which maintain PI over time. In the present study, N = 219 individuals completed momentary assessments of PI as well as four factors (attributing threats as certain and important, ruminating, and changing one's behavior in response) proposed to maintain PI over time. Linear mixed effects models were used to analyze multiple time-varying relationships, including these factors predicting negative affect and vice versa, as well as factors predicting maintenance of PI over time. Linear mixed effects models were used to analyze multiple time-varying relationships, examining each PI-related factor predicting negative affect, negative affect predicting each PI-related factor, as well as each factor predicting maintenance of PI over time. All four factors were associated with increases in subsequent day self-reported severity of PI, suggesting all four increased the likelihood of maintaining or worsening next-day PI. Results of this study confirm that the proposed factors are key in maintaining a cycle by which PI and negative affect are maintained over time. These factors may represent targets for momentary interventions.

Abstract
Importance Targeting low self-esteem in youth exposed to childhood adversity is a promising strategy for preventing adult mental disorders. Ecological momentary interventions (EMIs) allow for the delivery of youth-friendly, adaptive interventions for improving self-esteem, but robust trial-based evidence is pending. Objective To examine the efficacy of SELFIE, a novel transdiagnostic, blended EMI for improving self-esteem plus care as usual (CAU) compared with CAU only. Design, Setting, and Participants This was a 2-arm, parallel-group, assessor-blinded, randomized clinical trial conducted from December 2018 to December 2022. The study took place at Dutch secondary mental health services and within the general population and included youth (aged 12-26 years) with low self-esteem (Rosenberg Self-Esteem Scale [RSES] <26) exposed to childhood adversity. Interventions A novel blended EMI (3 face-to-face sessions, email contacts, app-based, adaptive EMI) plus CAU or CAU only. Main Outcomes and Measures The primary outcome was RSES self-esteem at postintervention and 6-month follow-up. Secondary outcomes included positive and negative self-esteem, schematic self-beliefs, momentary self-esteem and affect, general psychopathology, quality of life, observer-rated symptoms, and functioning. Results A total of 174 participants (mean [SD] age, 20.7 [3.1] years; 154 female [89%]) were included in the intention-to-treat sample, who were primarily exposed to childhood emotional abuse or neglect, verbal or indirect bullying, and/or parental conflict. At postintervention, 153 participants (87.9%) and, at follow-up, 140 participants (80.5%), provided primary outcome data. RSES self-esteem was, on average, higher in the experimental condition (blended EMI + CAU) than in the control condition (CAU) across both postintervention and follow-up as a primary outcome (B = 2.32; 95% CI, 1.14-3.50; P < .001; Cohen d-type effect size [hereafter, Cohen d] = 0.54). Small to moderate effect sizes were observed suggestive of beneficial effects on positive (B = 3.85; 95% CI, 1.83-5.88; P < .001; Cohen d = 0.53) and negative (B = -3.78; 95% CI, -6.59 to -0.98; P = .008; Cohen d = -0.38) self-esteem, positive (B = 1.58; 95% CI, 0.41-2.75; P = .008; Cohen d = 0.38) and negative (B = -1.71; 95% CI, -2.93 to -0.48; P = .006; Cohen d = -0.39) schematic self-beliefs, momentary self-esteem (B = 0.29; 95% CI, 0.01-0.57; P = .04; Cohen d = 0.24), momentary positive affect (B = 0.23; 95% CI, 0.01-0.45; P = .04; Cohen d = 0.20), momentary negative affect (B = -0.33; 95% CI, -0.59 to -0.03, P = .01, Cohen d = -0.27), general psychopathology (B = -17.62; 95% CI, -33.03 to -2.21; P = .03; Cohen d = -0.34), and quality of life (B = 1.16; 95% CI, 0.18-2.13; P = .02; Cohen d = 0.33) across postintervention and follow-up. No beneficial effects on symptoms and functioning were observed. Conclusions and Relevance A transdiagnostic, blended EMI demonstrated efficacy on the primary outcome of self-esteem and signaled beneficial effects on several secondary outcomes. Further work should focus on implementing this novel EMI in routine public mental health provision. Trial Registration Dutch Trial Register Identifier:NL7129(NTR7475).

Abstract
INTRODUCTION The relationship between interpersonal trauma and psychosis is well established, and research is now focused on identifying mechanisms that may explain this relationship. Models of trauma and psychosis increasingly emphasize a broad range of affective processes, yet the overall effect of these affective processes is not well understood. AIM This review systematically examined the effect of any form of long-term affective dysfunction on the relationship between interpersonal trauma and psychosis. Where possible, it used meta-analytic techniques to quantify the overall magnitude of this effect. METHOD Searches were conducted using PsychINFO, MEDLINE and CINAHL databases, and eligible studies were appraised for methodological quality. Narrative synthesis and meta-analytic methods were used to evaluate evidence. RESULTS Twenty-nine studies met criteria for inclusion. Five affective mediators were found; depression, anxiety, affective dysregulation, loneliness and attachment. Findings from both the narrative synthesis (n = 29) and meta-analysis (n = 8) indicated that, overall, affect is a small but significant mediator of the relationship between interpersonal trauma and psychosis (pooled Cohen's d = 0.178; pooled 95 % CI: 0.022-0.334). CONCLUSIONS Overall, findings support affective pathways to psychosis, though highlight the need for further research on broader affective mediators (loneliness, shame). The small effect size found in the meta-analysis also points to the potential importance of non-affective mediators. Clinically, these findings highlight the value of treatment modalities that attend to multiple mechanisms in the relationship between interpersonal trauma and psychosis. Future research should focus on the interplay and causal sequence between these mechanisms to further understand pathways between interpersonal trauma and psychosis.

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
Although mostly considered distinct, conspiracy mentality and paranoia share conceptual similarities (e.g., persecutory content, resistance to disconfirming evidence). Using self-report data from a large and multinational online sample (N = 2510; from the UK, the US, Hong Kong, Germany, and Australia), we examined whether paranoia and conspiracy mentality represent distinct latent constructs in exploratory and confirmatory factor analyses. Utilising network analysis, we then explored common and unique correlates of paranoia and conspiracy mentality while accounting for their shared variance. Across sites, paranoia and conspiracy mentality presented distinct, yet weakly correlated (r = 0.26), constructs. Both were associated with past traumatic experiences, holding negative beliefs about the self and other people, sleep problems, and a tendency to worry. However, paranoia was related to increased negative affect (i.e., anxiety) and decreased social support, whereas the opposite pattern was observed for conspiracy mentality (i.e., decreased anxiety and depression, increased social support). Paranoia and conspiracy mentality are related but not the same constructs. Their similar and distinct correlates point to common and unique risk factors and underlying mechanisms.

Abstract
BACKGROUND AND OBJECTIVES Worrying, self-esteem, sleep problems, anomalous internal experiences, reasoning biases, and interpersonal sensitivity are associated with paranoia. However, no review has examined whether these variables function as predictors of paranoia in everyday life. The present systematic review of intensive longitudinal studies (e.g., experience sampling) examined contemporaneous and time-lagged associations between paranoia and each candidate mechanism in individuals with non-affective psychosis and controls (pre-registration: https://osf.io/uwr9d). METHODS We searched electronic databases, PsyArXiv, and reference lists for studies published since 1994. RESULTS Of n = 5,918 results, n = 54 fulfilled inclusion criteria (n = 43 datasets). Most studies examined individuals with non-affective psychosis (n = 34). Strong evidence emerged for negative affect (subsumed under 'anomalous internal experiences') and sleep problems. For self-esteem, results suggest contemporaneous and lagged effects on paranoia but associations are likely driven by between-person variance. The low number of studies (n = 2 studies each) allowed no conclusions regarding worrying and reasoning biases. Findings on interpersonal sensitivity, which should be interpreted with caution because of the predictor's conceptual overlap with paranoia, indicate contemporaneous effects whereas time-lagged and within-person associations could not be judged due to insufficient data. LIMITATIONS The present review used a narrative data-synthetization and it did not cover outcomes such as hallucinations. CONCLUSIONS Despite convincing evidence for affect and sleep problems, it remains unclear whether affective states are precursors or also consequences of paranoia (vicious circle), and which of the actigraphy measures (sleep time, -efficiency, -fragmentation, etc.) best predicts 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
The quantity and quality of social contacts have been related to self-esteem, and both social relationships and self-esteem have been implicated in the pathways to paranoia. However, how social relationships interplay with self-esteem to trigger paranoia is not well understood. This study aims to investigate whether different measures of social connectedness (social support, loneliness, and desired friendship), as well as the frequency of social contact, impact paranoia and other positive and negative psychotic-like experiences (PLE) through the indirect effect of self-esteem. Data from a sample of 169 nonclinically ascertained participants oversampled for schizotypy scores were analyzed using two different approaches: retrospective trait-like and ecological momentary measures of social connectedness. Results showed that self-esteem mediates the pathways from poor social support and social longing, but not from loneliness, to paranoia and other cognitive PLE. In contrast, pathways from social connectedness to perceptual PLE and negative PLE were not mediated by self-esteem. Results were consistent across trait-like and momentary measures. Finally, self-esteem was not implicated in the pathways from the frequency of social contact and paranoia or other forms of PLE. These results provide a comprehensive picture of how social connectedness drives specific symptoms of psychosis through self-esteem. Findings underscore the need to explore separately the quality and quantity of social relationships and suggest that the subjective experience of meaningful social bonds is key social determinants of mental health. Therefore, addressing inadequacies of social connectedness could substantially improve symptomatic and functional outcomes of psychosis.

Abstract
BACKGROUND Recent network models propose that mutual interaction between symptoms has an important bearing on the onset of schizophrenic disorder. In particular, cross-sectional studies suggest that affective symptoms may influence the emergence of psychotic symptoms. However, longitudinal analysis offers a more compelling test for causation: the European Schizophrenia Cohort (EuroSC) provides data suitable for this purpose. We predicted that the persistence of psychotic symptoms would be driven by the continuing presence of affective disturbance. METHODS EuroSC included 1208 patients randomly sampled from outpatient services in France, Germany and the UK. Initial measures of psychotic and affective symptoms were repeated four times at 6-month intervals, thereby furnishing five time-points. To examine interactions between symptoms both within and between time-slices, we adopted a novel technique for modelling longitudinal data in psychiatry. This was a form of Bayesian network analysis that involved learning dynamic directed acyclic graphs (DAGs). RESULTS Our DAG analysis suggests that the main drivers of symptoms in this long-term sample were delusions and paranoid thinking. These led to affective disturbance, not vice versa as we initially predicted. The enduring relationship between symptoms was unaffected by whether patients were receiving first- or second-generation antipsychotic medication. CONCLUSIONS In this cohort of people with chronic schizophrenia treated with medication, symptoms were essentially stable over long periods. However, affective symptoms appeared driven by the persistence of delusions and persecutory thinking, a finding not previously reported. Although our findings as ever remain hostage to unmeasured confounders, these enduring psychotic symptoms might nevertheless be appropriate candidates for directly targeted psychological interventions.

Abstract
BACKGROUND Social cognition is often aberrant or impaired in psychotic disorders and related to functional outcomes. In particular, one core social cognitive bias - hostile attribution bias - is proposed to be implicated in paranoia, anxiety, mood disturbances and interpersonal conflict outcomes. However, questions remain about this domain's specificity to psychosis and its relationship to general functional outcomes. AIMS The present paper offers a descriptive and critical review of the literature on hostile attribution bias in psychotic disorders, in order to examine (1) its impact on persecutory symptoms in schizophrenia-spectrum disorders, (2) impact on other related psychopathology among those experiencing psychosis and (3) relationship to functioning. METHODS Twenty-eight studies included in this review after parallel literature searches of PsycINFO and PubMed. RESULTS Evidence from these studies highlighted that hostile attribution bias is elevated in schizophrenia, and that it is related to anxiety, depression and interpersonal conflict outcomes. CONCLUSION While results suggest that hostile attributions are elevated in schizophrenia and associated with symptoms and functioning, there exist numerous persisting questions in the study of this area, including identifying which measures are most effective and determining how it presents: as a state or trait-like characteristic, via dual processes, and its situational variation.

Abstract
There is currently limited research examining self-structure in clinical groups and no current data on the extent to which self-structure is amendable to change following psychological therapy. We address this important gap by examining self-structure in individuals with persecutory delusions using the card sort task, an established paradigm measuring key self-structure indices, including the degree to which self-structure is compartmentalized (characterized by primarily positive or negative attributes, as opposed to a mix of both), and the proportion and importance of negative attributes. In Study 1, individuals with a schizophrenia spectrum diagnosis with current persecutory delusions (clinical group, n = 27) and a healthy control group (n = 47) were compared on self-structure indices. In Study 2 (n = 27), the clinical group also completed the card sort task before and after randomization to either a 12-week mindfulness-based psychological therapy or treatment-as-usual control. In Study 1, self-structure differed significantly between the clinical and control groups. The clinical group had a greater proportion of negative attributes, assigned more importance to negative self-aspects, and had more compartmentalized self-structures compared with controls. In Study 2 there were no associations between delusion severity and self-structure. Large effect sizes for reductions in compartmentalization and proportion of negative attributes across self-aspects were found following mindfulness therapy. The findings highlight key differences in self-structure between individuals with persecutory delusions and healthy controls, and suggest that it might be possible to change self-structure following psychological therapy. These data support the central role of the self in theoretical models of paranoid thinking.

Abstract
Objectives Though often a feature of schizophrenia-spectrum disorders, persecutory ideation (PI) is also common in other psychiatric disorders as well as among individuals who are otherwise healthy. Emerging technologies allow for a more thorough understanding of the momentary phenomenological characteristics that determine whether PI leads to significant distress and dysfunction. This study aims to identify the momentary phenomenological features of PI associated with distress, dysfunction, and need for clinical care. Methods A total of 231 individuals with at least moderate PI from 43 US states participated in a study involving 30 days of data collection using a smartphone data collection system combining ecological momentary assessment and passive sensors, wherein they reported on occurrence of PI as well as related appraisals, responses, and cooccurring states. Most (N = 120, 51.9%) participants reported never having received treatment for their PI, while 50 participants had received inpatient treatment (21.6%), and 60 (26.4%) had received outpatient care only. Results Individuals with greater functional disability did not differ in PI frequency but were more likely at the moment to describe threats as important to them, to ruminate about those threats, to experience distress related to them, and to change their behavior in response. Groups based on treatment-seeking patterns largely did not differ in baseline measures or momentary phenomenology of PI as assessed by self-report or passive sensors. Conclusions Smartphone data collection allows for granular assessment of PI-related phenomena. Functional disability is associated with differences in appraisals of and responses to PI at the moment.

Abstract
A feeling of vulnerability is believed to be one of the foundations upon which paranoia is built. Factors that may increase vulnerability include negative affective states, low self-esteem and high social rejection sensitivity. Body image, which is one aspect of the overall self-esteem, has recently been shown to be associated with paranoia. However, little is known about factors underlying this association. In this online study conducted on a non-clinical sample (n = 539, 65.5% of female), self-report data assessing paranoia-like thoughts, body image, self-esteem, negative emotions, rejection sensitivity as well as various attitudes and beliefs related to body appearance were collected. The results revealed a significant serial mediation effect of negative emotions, self-esteem and rejection sensitivity in the relationship between body image and paranoia-like thoughts. Parallel mediation analysis showed an effect of social criticism as the only one of four studied groups of beliefs related to body appearance in the relationship between paranoia-like thoughts and body image. Moreover, paranoia-like thoughts were increased in people who were not satisfied with their body, both as a result of feeling too thin and overweight. To conclude, body image is an important factor related to paranoia-like thoughts, through its association with increased vulnerability and negative general self-view. The findings highlight the importance of negative emotions, low self-esteem and high rejection sensitivity, as well as the role of critical comments and lack of perceived acceptance as potential (socially-focused) mechanisms paving the way from negative body image to paranoia-like thoughts.

Abstract
BACKGROUND One putative psychological mechanism through which momentary stress impacts on psychosis in individuals with increased liability to the disorder is via affective disturbance. However, to date, this has not been systematically tested. We aimed to investigate whether (i) cross-sectional and temporal effects of momentary stress on psychotic experiences via affective disturbance, and (ii) the reverse pathway of psychotic experiences on stress via affective disturbance were modified by familial liability to psychosis. METHODS The Experience Sampling Method was used in a pooled data set of six studies with three groups of 245 individuals with psychotic disorder, 165 unaffected first-degree relatives, and 244 healthy control individuals to index familial liability. Multilevel moderated mediation models were fitted to investigate indirect effects across groups cross-sectionally and multilevel cross-lagged panel models to investigate temporal effects in the proposed pathways across two measurement occasions. RESULTS Evidence on indirect effects from cross-sectional models indicated that, in all three groups, effects of stress on psychotic experiences were mediated by negative affect and, vice versa, effects of psychotic experiences on stress were mediated by negative affect, with all indirect effects being weakest in relatives. Longitudinal modelling of data provided no evidence of temporal priority of stress in exerting its indirect effects on psychotic experiences via affective disturbance or, vice versa. CONCLUSIONS Our findings tentatively suggest a rapid vicious cycle of stress impacting psychotic experiences via affective disturbances, which does, however, not seem to be consistently modified by familial liability to psychosis.

Abstract
Background Paranoid ideation is a core feature of psychosis and is associated with impaired social functioning. Severity of paranoia can fluctuate across time as symptoms wax and wane; however, no study has systematically investigated how this intra-individual variability in paranoia may relate to social impairments and social functioning. Methods Fifty-five patients with DSM-5 diagnoses and recent paranoia were followed for up to one year and completed the suspiciousness/persecution section (P6) of the Positive and Negative Symptom Scale (PANSS) on a monthly basis to monitor fluctuations in paranoia. Categorical changes between paranoid and non-paranoid status were monitored and tallied. Participants self-reported current paranoia and anxiety levels as well as social functioning when demonstrating paranoia changes. Results Most patients showed changes between paranoid categories (60%). Individuals with no paranoia change showed higher current paranoia and lower independence-competence subscores of the Birchwood Social Functioning Scale (SFS) compared with those with one change. Current paranoia and state anxiety explained significant variance in the prosocial activities subscore of SFS, and importantly, paranoia changes accounted for variance above and beyond these effects. Individuals with higher current paranoia participated less in prosocial activities, however those with higher paranoia variability were more involved in social activities. Similarly, individuals with more paranoia variability demonstrated better overall social functioning as measured by the averaged SFS total score. Conclusion Paranoia fluctuation is prevalent across time, and both paranoia severity and variability impact social functioning, in that lower levels of paranoia severity and higher levels of paranoia variability are associated with better interpersonal functioning.

Abstract
The application of innovative technologies in psychiatry is promising, but the debate about its feasibility is not settled. Our aim was to investigate and compare adherence to and usability of 7-day monitoring with an Experience Sampling Method (ESM) and Actigraphy among a sample of individuals with a diagnosis of Schizophrenia Spectrum Disorders (SSD) and paired healthy controls. Twenty-two patients living in residential facilities (RFs), 20 outpatients and 26 controls were enrolled in this study as part of the DiAPAson project. Participants wore an actigraph and were evaluated for daily time use and mood with a smartphone-based ESM. Then, they completed questionnaires to assess the usability of the devices and were interviewed. Adherence was assessed as the percentage of time spent wearing actigraph and answering ESM notifications. Residential patients, compared to controls, showed significantly higher usability of the actigraph and lower adherence to both the actigraph and ESM. From the qualitative interviews, four high-order themes emerged: effects of monitoring, adherence and usability, emotions and mental states, and advice. Findings are promising for the application of these methodologies in such populations. The role of multidisciplinary staff in RFs is crucial for guaranteeing the realization of such projects.

Abstract
BACKGROUND AND HYPOTHESIS Influential models of psychosis indicate that the impact of putative causal factors on positive symptoms might be explained partly through affective disturbances. We aimed to investigate whether pathways from stress and self-esteem to positive symptoms, as well as reversal pathways from symptoms to stress and self-esteem, were mediated through specific affective disturbances across the extended psychosis phenotype. STUDY DESIGN Using experience sampling methodology, 178 participants (65 high-schizotypy, 74 at-risk mental state, and 39 first-episode psychosis) were assessed on levels of momentary stress, self-esteem, anxiety, sadness, psychotic-like experiences (PLE), and paranoia. Multilevel mediation models were fit to examine indirect effects of each of these pathways. Considering evidence of mediation, each indirect pathway will be combined in a single model to explore their relative contributions. STUDY RESULTS Anxiety, sadness, and self-esteem mediated the pathways from stress to PLE and paranoia in daily-life. In the pathway to paranoia, sadness, and self-esteem showed larger contributions than anxiety. Pathways from self-esteem to PLE and paranoia were mediated by anxiety and sadness, the later showing a larger contribution. Pathways from symptoms to stress, but not from symptoms to self-esteem, were differently explained by emotional states; sadness lost its mediating effect and anxiety was the most important mediator. Few differences across groups were found. CONCLUSIONS This study lends support to psychological models of psychosis that highlight the relevance of affective disturbances in the risk and expression of psychosis. Furthermore, specific influences of different negative emotional states were identified, which could enhance psychological treatments.

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.

Abstract
BACKGROUND This study tested the hypotheses that (i) the relationship between a history of childhood abuse and severity of psychosis is mediated by loneliness; (ii) the relationship between loneliness and psychosis is mediated by within-person fluctuations in depressive and anxious feelings. METHODS Fifty-nine individuals with non-affective psychotic disorder rated the intensity of loneliness, positive symptoms, and depressive and anxious feelings during repeated moments in daily life (Experience Sampling Method). Childhood abuse was assessed retrospectively using the 'Childhood Experience of Care and Abuse' interview. To test the mediation hypotheses, a multilevel structural equation modeling paradigm was used. RESULTS As predicted, the relationship between severity of childhood abuse and positive symptoms was mediated by loneliness (b=0.08, 95% CI [0.02, 0.13], p=0.005). In turn, the relationship between loneliness and positive symptoms was mediated by within-person fluctuations in both depressive (b=0.04, 95% CI [0.02, 0.06], p<0.001) and anxious (b=0.02, 95% CI [0.01, 0.03], p=0.002) symptomatology. Depression was a stronger mediator than anxiety (b=0.02, 95% CI [0.00, 0.04], p=0.027). CONCLUSIONS Our findings highlight the role of childhood abuse and loneliness in the severity of psychosis in daily life.

Abstract
It is found that people with psychotic experiences have a 4-fold increased risk of developing a psychotic disorder later in life. Indeed, accumulating evidence has suggested that the association between school bullying and psychotic experiences works linearly. Previous studies are mainly carried out in a Western context, and only seldomly do studies address whether the association exists in the Chinese population and the related psychological and cognitive mechanisms. Therefore, we carried out the current study to address this gap in the literature focusing on the lifelong school bullying experiences of Chinese adolescents and young adults. We examined them in relation to psychotic experiences while assessing the mediating role of self-esteem, the personality trait of neuroticism, and a cognitive bias in thinking called interpretation bias. We found that multiple victimizations were quite common in Hong Kong secondary schools. In addition to a significant association between school bullying and psychotic experiences, we found partial mediating effects of proposed psychological and cognitive mediators in constructed multiple mediation models utilizing bootstrapping approach. Specifically, bullying quantity reflecting the number of victimizations, had its association with psychotic experiences partially mediated by the personality trait of neuroticism. In contrast, bullying duration reflecting the lasting of victimization was associated with psychotic experiences partially mediated by the personality trait of neuroticism and interpretation bias. Our findings enhance our knowledge of mechanisms underpinning the psychosis spectrum development and have implications for school-based intervention programs targeting bullying victims.

Abstract
In the present study, we explore the proposed cyclic models for problematic hypersexuality (PH) that involve shame, self-esteem, and sexual desire. These cyclic models are characterized by temporal associations but have not been investigated previously with intensive longitudinal designs. In this study, we collected up to 70 measurements per participant within a period of seven consecutive days, which allowed us to investigate associations between fluctuations of shame, self-esteem, and sexual desire. Participants were divided in four subgroups: (1) women (n = 87); (2) men (n = 46) from a general population convenience sample; (3) men watching porn >2 times per week, showing non-problematic hypersexuality (NH; n = 10); and (4) men watching porn >2 times per week, experiencing PH (n = 11). Multilevel analyses, including cross-level interactions, were used to investigate between-group differences in intraindividual processes. Results showed that prior increases in shame forecasted higher current sexual desire for men with PH, but not for the other groups, suggesting that men with PH use sexual desire to downregulate dysphoric feelings of shame. Differences between groups in associations between self-esteem and sexual desire were also found. Based on our results, we propose the Split Pleasure/Shame model, which represents emotion dysregulation in PH, and juxtapose this with the pleasurable experience of sex by non-PH groups. Further intensive longitudinal research is necessary to test this model and, more generally, to investigate the fluctuating nature of sexual desire.

Abstract
OBJECTIVE Three studies tested a novel model of the narcissism-paranoia link, whereby narcissism (primarily its socially maladaptive facets) is associated with paranoia via over-use of defensive self-protection and/or under-use of self-affirmation. METHODS In Study 1, 245 online volunteers (87% female; MAGE = 20.92; 44% White-British) completed trait measures of narcissism, self-enhancement/protection strategies and paranoia. In Study 2, 116 students (82% female; MAGE = 20.23; 70% White-British) completed baseline measures, then reported state reactions and paranoia following two difficult and two pleasant interpersonal events after 3-10 days. In Study 3, 517 online volunteers (64% female; MAGE = 22.76; 77% White/Caucasian) completed baseline measures, experienced a standardized social exclusion (vs. neutral) manipulation (Cyberball), then reported state reactions and paranoia. RESULTS In Study 1, narcissism was associated with higher paranoia via defensiveness. In Study 2, this was replicated in difficult but not pleasant events, and was driven by the Entitlement/Exploitativeness facet of narcissism. In Study 3, narcissistic rivalry and vulnerable narcissism, but not admiration, were associated with Cyberball-related paranoia via general defensiveness and denigration of others. CONCLUSIONS Individuals high in narcissism-especially its socially maladaptive facets-who over-rely on defensive self-protection strategies in response to threat, are particularly vulnerable to paranoia. Findings help to understand individual differences in paranoia.

Abstract
OBJECTIVE Low self-esteem has been suggested as a putative mechanism in the development and maintenance of psychosis. Uncertainty still exists about how unstable self-esteem relates to psychotic experiences. The present study examines the potential (temporal) associations between momentary self-esteem, fluctuations in self-esteem, and psychotic experiences in daily life. METHODS Experience sampling data were collected from 46 individuals presenting with an at-risk mental state (ARMS), 51 individuals with first-episode psychosis (FEP), and 53 controls, to investigate associations between (fluctuations in) self-esteem and psychotic experiences within and across FEP, ARMS, and controls, using linear mixed models. RESULTS In all three groups we found that lower momentary self-esteem was associated with a greater intensity of psychotic experiences (adj. βFEP = -0.15, 95% CI -0.20 to -0.10, p = 0.000; adj. βARMS = -0.20, 95% CI -0.26 to -0.15, p = 0.000; adj. βcontrols = -0.12, 95% CI -0.17 to -0.07, p = 0.000). Variability in momentary self-esteem was associated with a greater intensity of psychotic experiences only in ARMS (adj. βARMS = 0.08, 95% CI 0.04 to 0.11, p = 0.000) and controls (adj. βcontrols = 0.04, 95% CI 0.01 to 0.08, p = 0.023). For instability this association held only in controls (adj. βcontrols = 0.03, 95% CI 0.00 to 0.05, p = 0.020). Furthermore, findings may suggest a reciprocal temporal association between self-esteem and psychotic experiences. CONCLUSIONS Our findings suggest that self-esteem may be an important mechanism targetable by ecological momentary interventions to reduce the intensity of psychotic experiences and potentially prevent illness progression at an early stage.

Abstract
OBJECTIVE Accumulating evidence supports an association between residential instability and increased risk for psychosis, but the association between residential instability and conversion to psychosis among adolescents at clinical high risk (CHR) is unclear. In this study, we determined whether individual-level and area-level residential instability and their interaction are associated with conversion to psychosis within two years. METHODS Data were collected as part of the North American Prodrome Longitudinal Study Phase 2. Individual-level residential instability, defined as having ever moved during lifetime, was derived from the Life Events Scale. Area-level residential instability, defined as the percentage of people who were not living in the same house five years ago, was derived from the U.S. Decennial Censuses. RESULTS This study included 285 adolescents at CHR (including 36 subjects who later converted to full psychosis). We found that individual-level residential instability was associated with conversion (adjusted OR = 2.769; 95% CI = 1.037-7.393). The interaction between individual-level and area-level residential instability was significant (p = 0.030). In a subgroup of CHR participants who have never moved (n = 91), area-level residential instability during childhood was associated with conversion (adjusted OR = 1.231; 95% CI = 1.029-1.473). Conversely, in a subgroup of CHR participants who resided in residentially stable areas during childhood (n = 142), the association between individual-level residential instability and conversion remained significant (adjusted OR = 15.171; 95% CI = 1.753-131.305). CONCLUSIONS These findings suggest that individual-level and area-level residential instability may be associated with conversion to psychosis.

Abstract
BACKGROUND Targeting low self-esteem in youth exposed to childhood adversity is a promising strategy for preventing adult mental disorder, but psychological help remains difficult to access and accept for youth, calling for novel, youth-friendly approaches. Mobile Health (mHealth) and, most prominently, ecological momentary interventions (EMIs) provide a unique opportunity to deliver youth-friendly, personalized, real-time, guided self-help interventions. The aim of this study is to investigate the efficacy of a novel, accessible, transdiagnostic ecological momentary intervention for improving self-esteem ('SELFIE') in youth with prior exposure to childhood adversity. METHODS/DESIGN In a parallel-group, assessor-blind, multi-center randomized controlled trial, individuals aged 12-26 years with prior exposure to childhood adversity and low self-esteem will be randomly allocated to SELFIE in addition to treatment as usual (TAU) as the experimental condition or the control condition of TAU only, which will include access to all standard health care. SELFIE is a digital guided self-help intervention administered through a smartphone-based app to allow for interactive, personalized, real-time and real-world transfer of intervention components in individuals' daily lives, blended with three training sessions delivered by trained mental health professionals over a 6-week period. Outcomes will be assessed at baseline, post-intervention, and 6-month follow-up by blinded assessors. The primary outcome will be the level of self-esteem as measured with the Rosenberg Self-Esteem Scale (RSES). DISCUSSION The current study is the first to establish the efficacy of an EMI focusing on improving self-esteem transdiagnostically in youth exposed to childhood adversity. If this trial provides evidence on the efficacy of SELFIE, it has significant potential to contribute to minimizing the deleterious impact of childhood adversity and, thereby, preventing the development of mental disorder later in life.

Bemrose HV, Akande IO, Cullen AE. Self-esteem in individuals at ultra-high risk for psychosis: A systematic review and meta-analysis. Early Interv Psychiatry 2021; 15:775-786. [PMID: 32860493 DOI: 10.1111/eip.13034] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Revised: 07/22/2020] [Accepted: 08/02/2020] [Indexed: 11/27/2022]
Abstract
AIM Low self-esteem (LSE) has been reported among individuals with psychosis and is hypothesized to act as a risk and maintenance factor for the disorder. However, the extent to which LSE also characterizes individuals deemed at ultra-high risk (UHR) for psychosis (who present features consistent with the prodromal phase of illness), has yet to be quantified using meta-analysis. This is important given that LSE is a potentially modifiable target for early intervention services aiming to reduce the risk of psychosis transition in this population. METHODS We searched Medline, Embase, PsycINFO and Web of Science Core Collection for studies examining self-esteem in UHR and healthy individuals. Random-effects models were used to examine group differences in self-esteem (Hedges'g) with exploratory meta-regression analyses employed to investigate the effect of study characteristics (mean age of UHR group, the proportion of male participants in the UHR group and study quality) on standardized mean differences. RESULTS Six studies were eligible for inclusion. Significant differences in self-esteem were observed, with individuals at UHR showing reduced self-esteem relative to healthy controls (g = -1.33 [-1.73 to -0.94] P < .001).However, there was evidence of substantial heterogeneity (I2 = 75%). Exploratory meta-regression analyses indicated a significant effect of the mean age of the UHR group on effect sizes (B = -0.26, P = .02). CONCLUSIONS UHR youth present with lower levels of self-esteem than healthy individuals, a difference that appears to be more pronounced with advancing age. We discuss clinical implications and provide recommendations for future studies.

Abstract
Abstract
Background
Negative affect reliably predicts paranoid thoughts. Previous studies point to the importance of emotion regulation for paranoid thoughts but have not yet focused on effects of acute increases and variability in strategy use.
Methods
We conducted an experience-sampling study for one week in a subclinical sample. Acute increases in the intensity of strategy use from one measurement point until the next, between-strategy variability (i.e., standard deviation between all strategies at one measurement point), and within-strategy variability (i.e., standard deviation of each strategy over one day) were analyzed for effects on negative affect and paranoid thoughts.
Results
Multi-level-models indicated that acute increases in acceptance and reappraisal are associated with less negative affect. Acute increases in acceptance, but not in reappraisal, were related to less paranoid thoughts. In contrast, acute increases in rumination and suppression were associated with more negative affect and paranoid thoughts. Between- and within-strategy variability were no significant predictors.
Conclusions
Acute increases in the intensity of but not variability in emotion regulation strategies are related to negative affect and paranoid thoughts in daily life. Future studies are needed to examine whether improving emotion regulation leads to sustainable reductions in symptoms.

Abstract
Researchers have measured social functioning in schizophrenia using many different strategies. Recent technological advances have made it possible to passively measure behaviors in real-world social situations-allowing for more objective, ecologically valid assessments. Yet, research testing the convergent validity among real-world and laboratory-based social functioning assessment is sparse. The purpose of this study was to test the convergent validity among four social functioning measures: two interview-based rating scales, a self-reported ecological momentary assessment (EMA), and a passive, ambulatory ecological assessment. Data was collected from 36 people with schizophrenia and 33 control participants. Across the entire sample, relationships between interview-based ratings and real-world measures of social functioning only demonstrated small correlations (r's = 0.17-0.19), whereas real-world measures exhibited moderate correlations with one another (r = 0.36). Within groups, real-world measures showed moderate, significant relationships in the control group (r = 0.44) but not in the schizophrenia group (r = 0.27). For those with schizophrenia, the interview-based measures of social functioning were moderately associated with ambulatory ecological assessment (r's = 0.38 and 0.47), but only small associations were observed with self-reported EMA (r's = 0.15 and 0.17). Results suggest social functioning assessments are not highly convergent and likely target different aspects of social functioning. Laboratory-based measures offer global impressions of social functioning whereas real-world measures represent a more nuanced approach. Moreover, ambulatory ecological assessment may most accurately gauge frequency of daily social interactions for those with schizophrenia as it circumvents common pitfalls of self-report and offers a less-biased, in-depth evaluation of social behavior.

Abstract
Abstract
Background
Paranoia is common in the general population. Focusing on values and enhancing value-based acts may attenuate it. This study compared three brief (30-min, self-directed) online conditions: focusing on values and value-based goal setting (n = 30), goal setting only (n = 32) and non-values/goals control (n = 32) in a high paranoia sample.
Methods
Participants were randomly assigned to condition. State paranoia (primary outcome) and positive and negative self-views following a difficult interpersonal experience (secondary outcome) were assessed at baseline and two-weeks.
Results
Intention-to-treat: state paranoia was significantly lower following the values condition as compared to non-values/goals control (ηp2 = .148) and goals only (ηp2 = .072). Only the former comparison was significant. Per-protocol: groups did not significantly differ (p = .077). Within-group effect sizes: values and value-based goal setting (intention-to-treat d = .82, per-protocol d = .78), goals only (intention-to-treat d = .41, per-protocol d = .42) non-values/goals control (intention-to-treat d = .25, per-protocol d = .24). Positive self-views increased in all conditions. The increase was largest for the values condition, but not significantly so.
Limitations
Reliance on self-report, brief follow-up, predominantly White female sample.
Conclusions
The values condition was most effective at reducing non-clinical paranoia. The values condition appeared to increase positive self-views more so than comparison groups, but the sample was small and the difference was non-significant.

Abstract
BACKGROUND Patients with psychotic disorders report to apply more maladaptive and less adaptive emotion-regulation (ER) strategies compared to healthy controls. However, few studies have used experimental designs to investigate the success in ER and the results of those at hand are equivocal. AIM This study investigated whether patients with delusions show problems in downregulating negative affect via cognitive ER-strategies. METHOD Patients with schizophrenia spectrum disorders and acute delusions (n = 78) and healthy controls (n = 41) took part in an ER-experiment, in which they were instructed to downregulate anxiety and sadness via three ER-strategies (reappraisal, distraction, acceptance) or not to regulate their emotions (control-condition). ER-success was measured as the change in subjective emotion-intensity and physiological indicators (skin conductance and heart rate) from before to after regulation and was analyzed with mixed-repeated-measures ANOVAs. RESULTS We found a significant effect of the ER-strategy in the sense that the subjective emotion-intensity was significantly lower after applying the reappraisal- and distraction-strategies than after the just view-condition (p's < .001). This effect was not found for the acceptance strategy (p = .060). There was no ER-strategy ∗ time ∗ group interaction-effect F(4.918, 575.416) = 0.778, p = .564, ƞ2partial = 0.007. In all conditions, skin conductance decreased from pre- to post regulation (p < .001). CONCLUSION Our results indicate that patients with acute delusions can successfully apply cognitive ER-strategies. Before pursuing the relevant clinical implications of this finding, further research is needed to explore the role that the type of instruction has on ER-success and the extent to which the findings can be generalized to real life settings.

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
Abstract
Background
Research on emotion regulation and paranoid ideation has mostly focused on isolated regulation strategies and has remained largely inconclusive. According to the emotion regulation model by Berking and Whitley (in: Affect Regulation Training, Springer, New York 2014) successful modification or acceptance/tolerance of emotions requires an adequate comprehension (awareness, clarity, understanding) of emotions and adequate self-support.
Method
Building on this model, we investigated whether comprehension and self-support strengthen the negative association between modification and acceptance/tolerance and paranoid ideation. In study 1, we examined the hypotheses cross-sectionally based on questionnaire data from a combined sample (N = 125) consisting of people with a psychotic disorder, people at risk of developing psychosis, and healthy controls. In study 2, we examined the same hypotheses longitudinally by employing the experience sampling method in people with clinically relevant psychopathology below diagnostic threshold (N = 138).
Results
In study 1, the association between modification and paranoid ideation was not moderated by comprehension or self-support. However, comprehension and self-support moderated the association between acceptance/tolerance and paranoid ideation. In study 2, the interaction effect between comprehension and acceptance/tolerance on paranoid ideation was confirmed.
Conclusion
The results indicate that comprehending and accepting/tolerating emotions could be protective against paranoid ideation.

Abstract
As stress is relevant to the formation of paranoia, maladaptive behavioral and physiological stress regulation is discussed as a crucial indicator of vulnerability. This is supported by research linking psychosis to the tendency to make less use of functional and more use of dysfunctional emotion regulation strategies (ER) and with a lower vagally-mediated heart rate variability (HRV). However, it remains unclear whether ER serves as a mediator between resting-state HRV on the one hand and subjective stress levels and paranoia on the other and whether this is specific to paranoia as compared to depression. We used an experience sampling method during seven days to repeatedly assess the experience of stress, usage of ER strategies, paranoia und depression (9/day) in a sample with subclinical positive symptoms (N = 32). Resting-state HRV was measured during a 5min interval in the laboratory. Data was analyzed by multi-level models. Higher resting-state HRV was predictive of lower stress-levels and of using more functional ER strategies (reappraisal, acceptance) in daily life, but did not predict the use of dysfunctional strategies (rumination, suppression) or paranoia. The association between resting-state HRV and stress was mediated by the usage of functional ER. Less functional and more dysfunctional ER were linked to higher levels of stress, paranoia and depression. Our study highlights that deficits in ER represent a link between psychophysiological and phenomenological aspects of paranoia but also of depression. This encourages to further investigate transdiagnostic prevention and therapy programs aiming to improve ER and to increase HRV.

Abstract
We investigated (a) whether psychosocial factors (experienced stress, anticipatory worry, social detachment, sleeping disturbances, alcohol use) predict the course of paranoid ideation between the ages of 24 to 50 years and (b) whether the predictive relationships are more likely to proceed from the psychosocial factors to paranoid ideation, or vice versa. The participants (N = 1534-1553) came from the population-based Young Finns study. Paranoid ideation and psychosocial factors were assessed by reliable self-report questionnaires in 2001, 2007, and 2011/2012. The data were analyzed using growth curve and structural equation models. High experienced stress, anticipatory worry, social detachment, frequent sleeping disturbances, and frequent alcohol use predicted more paranoid ideation. More risk factors predicted increasing paranoid ideation. There were bidirectional predictive relationships of paranoid ideation with experienced stress, anticipatory worry, social detachment, and sleeping disturbances. The link between alcohol use and paranoid ideation was only correlative. In conclusion, paranoid ideation increases by reciprocal interactions with stress, worry, social detachment, and sleeping disturbances. The findings support the threat-anticipation model of paranoid ideation, providing important implications for treatment of paranoia.

Abstract
Abstract
Background
Emotion-regulation is assumed to be impaired in psychosis: patients with psychotic disorders (PD) self-report to use reappraisal less frequently than healthy controls (HC), but it is uncertain whether they are also less successful in applying reappraisal. Moreover, it has not been investigated whether the habitual use of reappraisal is associated with the ability to use reappraisal successfully.
Methods
To address these questions, PD (n = 60), a clinical control group of patients with anxiety disorders (AD; n = 40) and HC (n = 40) completed questionnaires on habitual emotion-regulation and alexithymia, performed tests on neurocognitive functioning and jumping-to-conclusion bias, and were subjected to an emotion-regulation paradigm, in which they were asked to down-regulate induced anxiety and sadness.
Results
No differences were found between PD and HC regarding the habitual use of reappraisal, but PD reported to use reappraisal more frequently than AD. All groups were able to down-regulate anxiety and sadness via reappraisal following instructions. The habitual use of reappraisal and the reduction of anxiety and sadness after instruction were uncorrelated.
Conclusion
These findings question the common assumption that PD use reappraisal less often or less successfully. At least under laboratory condition, PD do not appear to be impaired in reducing negative affect via reappraisal successfully.

Abstract
Paranoid beliefs have been conceptualized as a central psychological process linked to schizophrenia and many mental disorders. Research on paranoia has indicated that it is pivotal to consider not only levels but also dynamic aspects of incriminated related mechanisms over time. In the present study, we conceptualized paranoia as a system of interacting elements. To do so, we used temporal network analysis to unfold the temporal dynamics between core psychological paranoia-related mechanisms, such as self-esteem, sadness, feeling close to others, and experiential avoidance. Time-series data of 23 participants with high scores in paranoia and/or interpersonal sensitivity were collected via experience sampling methodology (ESM). We applied a multilevel vector autoregressive (mlVAR) model approach and computed three distinct and complementary network models (i.e., contemporaneous, temporal, and between-subject) to disentangle associations between paranoia-related mechanisms in three different time frames. The contemporaneous model indicated that paranoia and sadness co-occurred within the same time frame, while sadness was associated with both low self-esteem and lack of closeness to others. The temporal model highlighted the importance of feeling close to others in predicting low paranoia levels in the next time frame. Finally, the between-subject model largely replicated an association found in both contemporaneous and temporal models. The current study reveals that the network approach offers a viable data-driven methodology for elucidating how paranoia-related mechanisms fluctuate over time and may determine its severity. Moreover, this novel perspective may open up new directions toward identifying potential targets for prevention and treatment of paranoia-related problems.

Abstract
Background No studies have examined the association between self‐esteem and paranoia developmentally across the critical stages of psychosis emergence. The present study fills this gap and extends previous research by examining how different dimensions, measures, and types of self‐esteem relate to daily‐life paranoia across at‐risk mental states for psychosis (ARMS) and first episode of psychosis (FEP) stages. Furthermore, the moderation effects of momentary anxiety and momentary perceived social support on the association between momentary self‐esteem and paranoia were examined. Design This study used a multilevel, cross‐sectional design. Methods One‐hundred and thirteen participants (74 ARMS and 39 FEP) were assessed repeatedly over seven consecutive days on levels of momentary paranoia, self‐esteem, anxiety and perceived social support using experience sampling methodology. Measures of trait and implicit self‐esteem were also collected. Results Global momentary and trait self‐esteem, and their positive and negative dimensions, were related to daily‐life paranoia in both ARMS and FEP groups. Conversely, implicit self‐esteem was not associated with daily‐life paranoia in either group. Anxiety negatively moderated the association between positive self‐esteem and lower paranoia, whereas both feeling close to others and feeling cared for by others strengthened this association. However, only feeling cared for by others moderated the association between negative self‐esteem and higher paranoia. Conclusions Different types, measures and dimensions of self‐esteem are differentially related to paranoia in early psychosis and are influenced by contextual factors in daily‐life. This yields a more complex picture of these associations and offers insights that might aid psychological interventions. Practitioner points Different measures (trait and momentary) and dimensions (positive and negative) of explicit self‐esteem are distinctly related to paranoia across risk and first‐episode stages of psychosis. Explicit, but not implicit, self‐esteem is associated with real‐life paranoia in incipient psychosis. Anxiety boosted the association of poor self‐esteem and paranoia ideation in daily‐life. Social closeness, but feeling cared for by others in particular, interacts with self‐esteem tempering the expression of paranoia in real life.

Virtual reality based cognitive behavioral therapy for paranoia: Effects on mental states and the dynamics among them. Schizophr Res 2020; 222:227-234. [PMID: 32527676 DOI: 10.1016/j.schres.2020.05.047] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Revised: 03/31/2020] [Accepted: 05/18/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND Negative affective processes may contribute to maintenance of paranoia in patients with psychosis, and vice versa. Successful treatment may break these pathological symptom networks. This study examined whether treatment with virtual reality based cognitive behavioral therapy (VR-CBT) for paranoia influences momentary affective states, and whether VR-CBT changes the adverse interplay between affective states and paranoia. METHODS Patients with a psychotic disorder (n = 91) were randomized to 16-session VR-CBT or treatment as usual (TAU). With the experience sampling method (structured diary technique) mental states were assessed for 6-10 days at baseline, posttreatment and 6-month follow-up. Multilevel analysis were performed to establish treatment effects and time-lagged associations between mental states, that were visualized with networks of mental states. RESULTS Average levels of paranoia (feeling suspicious [b = -032., p = .04], disliked [b = -49., p < .01] and hurt [b = -0.52, p < .01]) and negative affect (anxious [b = -0.37, p = .01], down [b = -0.33, p = .04] and insecure [b = -0.17, p = .03) improved more after VR-CBT than TAU, but positive affect did not. Baseline mental state networks had few significant connections, with most stable connections being autocorrelations of mental states. The interplay between affective states and paranoia did not change in response to treatment. A trend reduction in average intranode connections (autocorrelations) was found after VR-CBT (b = -0.07, p = .08), indicating that mental states reinforce themselves less after treatment. CONCLUSIONS VR-CBT reduced paranoid symptoms and lowered levels of negative affect in daily life, but did not affect the extent to which mental states influenced each other. Findings do suggest that as a result of treatment mental states regain flexibility.

Temporal dynamics of suspiciousness and hallucinations in clinical high risk and first episode psychosis. Psychiatry Res 2020; 290:113039. [PMID: 32460186 DOI: 10.1016/j.psychres.2020.113039] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2019] [Revised: 04/22/2020] [Accepted: 04/24/2020] [Indexed: 12/23/2022]
Abstract
The objective of the current study is to elucidate the temporal dynamics of suspiciousness and hallucinations as they occur in daily life in the early stages of psychosis. Their prevalence and co-occurrence, as well as their temporal relation to affect and delusions, were compared between patients with a first psychotic episode (FEP) and individuals at clinical high risk for psychosis (CHRp). The Experience Sampling Method was used to investigate suspiciousness and hallucinatory experiences, delusions, and affect at semi-random moments throughout six days in 33 CHRp and 34 FEP. Overall, 91% of CHRp and 59% of FEP reported suspiciousness, and 24% and 39% reported hallucinations, respectively. Hallucinations almost always co-occurred with suspiciousness, whereas suspiciousness was often present without hallucinations. Suspicious episodes in CHRp occurred with marked increases in delusional intensity, while hallucinatory experiences were mostly absent. In FEP, a decrease of positive affect preceded suspicious episodes, while an increase of negative affect preceded hallucinatory episodes. Our results indicated the presence of a delusional mood (atmosphere) in CHRp as an experience in itself, without co-occurring or following hallucinations, thus refuting the anomalous experience hypothesis of psychosis. The co-occurrence of hallucinations, on the other hand, indicates a more severe stage of symptomatology.

Abstract
BACKGROUND Psychosis is an illness characterised by alterations in thoughts and perceptions resulting in delusions and hallucinations. Psychosis is rare in adolescents but can have serious consequences. Antipsychotic medications are the mainstay treatment, and have been shown to be effective. However, there is emerging evidence on psychological interventions such as cognitive remediation therapy, psycho-education, family therapy and group psychotherapy that may be useful for adolescents with psychosis. OBJECTIVES To assess the effects of various psychological interventions for adolescents with psychosis. SEARCH METHODS We searched the Cochrane Schizophrenia Group's study-based Register of Trials including clinical trials registries (latest, 8 March 2019). SELECTION CRITERIA All randomised controlled trials comparing various psychological interventions with treatment-as-usual or other psychological treatments for adolescents with psychosis. For analyses, we included trials meeting our inclusion criteria and reporting useable data. DATA COLLECTION AND ANALYSIS We independently and reliably screened studies and we assessed risk of bias of the included studies. For dichotomous data, we calculated risk ratios (RRs) and 95% confidence intervals (CIs) on an intention-to-treat basis. For continuous data, we used mean differences (MDs) and the 95% CIs. We used a random-effects model for analyses. We created a 'Summary of findings' table using GRADE. MAIN RESULTS The current review includes 7 studies (n = 319) assessing a heterogenous group of psychological interventions with variable risk of bias. Adverse events were not reported by any of the studies. None of the studies was sponsored by industry. Below, we summarise the main results from four of six comparisons, and the certainty of these results (based on GRADE). All scale scores are average endpoint scores. Cognitive Remediation Therapy (CRT) + Treatment-as-Usual (TAU) versus TAU Two studies compared adding CRT to participants' TAU with TAU alone. Global state (CGAS, high = good) was reported by one study. There was no clear difference between treatment groups (MD -4.90, 95% CI -11.05 to 1.25; participants = 50; studies = 1, very low-certainty). Mental state (PANSS, high = poor) was reported by one study. Scores were clearly lower in the TAU group (MD 8.30, 95% CI 0.46 to 16.14; participants = 50; studies = 1; very low-certainty). Clearly more participants in the CRT group showed improvement in cognitive functioning (Memory digit span test) compared to numbers showing improvement in the TAU group (1 study, n = 31, RR 0.58, 95% CI 0.37 to 0.89; very low-certainty). For global functioning (VABS, high = good), our analysis of reported scores showed no clear difference between treatment groups (MD 5.90, 95% CI -3.03 to 14.83; participants = 50; studies = 1; very low-certainty). The number of participants leaving the study early from each group was similar (RR 0.93, 95% CI 0.32 to 2.71; participants = 91; studies = 2; low-certainty). Group Psychosocial Therapy (GPT) + TAU versus TAU One study assessed the effects of adding GPT to participants' usual medication. Global state scores (CGAS, high = good) were clearly higher in the GPT group (MD 5.10, 95% CI 1.35 to 8.85; participants = 56; studies = 1; very low-certainty) but there was little or no clear difference between groups for mental state scores (PANSS, high = poor, MD -4.10, 95% CI -8.28 to 0.08; participants = 56; studies = 1, very low-certainty) and no clear difference between groups for numbers of participants leaving the study early (RR 0.43, 95% CI 0.15 to 1.28; participants = 56; studies = 1; very low-certainty). Cognitive Remediation Programme (CRP) + Psychoeducational Treatment Programme (PTP) versus PTP One study assessed the effects of combining two types psychological interventions (CRP + PTP) with PTP alone. Global state scores (GAS, high = good) were not clearly different (MD 1.60, 95% CI -6.48 to 9.68; participants = 25; studies = 1; very low-certainty), as were mental state scores (BPRS total, high = poor, MD -5.40, 95% CI -16.42 to 5.62; participants = 24; studies = 1; very low-certainty), and cognitive functioning scores (SPAN-12, high = good, MD 2.40, 95% CI -2.67 to 7.47; participants = 25; studies = 1; very low-certainty). Psychoeducational (PE) + Multifamily Treatment (MFT) Versus Nonstructured Group Therapy (NSGT, all long-term) One study compared (PE + MFT) with NSGT. Analysis of reported global state scores (CGAS, high = good, MD 3.38, 95% CI -4.87 to 11.63; participants = 49; studies = 1; very low-certainty) and mental state scores (PANSS total, high = poor, MD -8.23, 95% CI -17.51 to 1.05; participants = 49; studies = 1; very low-certainty) showed no clear differences. The number of participants needing hospital admission (RR 0.84, 95% CI 0.36 to 1.96; participants = 49; studies = 1) and the number of participants leaving the study early from each group were also similar (RR 0.52, 95% CI 0.10 to 2.60; participants = 55; studies = 1; low-certainty). AUTHORS' CONCLUSIONS Most of our estimates of effect for our main outcomes are equivocal. An effect is suggested for only four outcomes in the SOF tables presented. Compared to TAU, CRT may have a positive effect on cognitive functioning, however the same study reports data suggesting TAU may have positive effect on mental state. Another study comparing GPT with TAU reports data suggesting GPT may have a positive effect on global state. However, the estimate of effects for all the main outcomes in our review should be viewed with considerable caution as they are based on data from a small number of studies with variable risk of bias. Further data could change these results and larger and better quality studies are needed before any firm conclusions regarding the effects of psychological interventions for adolescents with psychosis can be made.

Abstract
BACKGROUND Early life adversity (ELA) is a significant risk factor for mental health disorders. One hypothesised mechanism by which this occurs is via an effect on immune response. In this analysis of epidemiological data, we tested whether ELA was associated with cognitive performance, and if so, whether these effects were influenced by immune function. METHODS We investigated the longitudinal relationship between ELA, inflammatory markers, and cognition in data from Avon Longitudinal Study of Parents And Children (ALSPAC; n ~ 5000). ELA was defined in terms of physical/emotional abuse, harsh parenting, or domestic violence before 5 years. Social cognition was measured in terms of theory of mind, and general cognitive ability was measured using IQ. Inflammatory markers included serum C-reactive protein and interleukin-6 levels. RESULTS A significant association was observed between IQ and harsh parenting, whereby children who were physically disciplined had lower IQ scores (accounting for relevant social factors). Both immune markers were associated with variation in cognition, however, neither accounted for the effects of ELA on cognition. DISCUSSION This study highlights the impact of ELA on cognition. In the absence of evidence that these effects are explained by inflammation, other mechanisms by which the effects of ELA are mediated are discussed.
