RESUMO
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.
RESUMO
Paranoia is the erroneous idea that people are targeting you for harm, and the cognitive model suggests that symptoms increase with emotional and relational distress. A factor potentially associated with paranoia is mistrust, a milder form of suspiciousness. This study investigated the longitudinal course of non-clinical paranoia in a sample of 739 students (age range 10-12 at baseline assessment, 12-14 at second assessment) using data from the Social Mistrust Scale (SMS) and the paranoia subscale of the Specific Psychotic Experiences Questionnaire (SPEQ). Prevalence of mistrustful and high paranoia children was 14.6 and 15% respectively. Independently, baseline internalizing symptoms (b = 0.241, p < 0.001) and mistrust (b = 0.240, p < 0.001) longitudinally predict paranoia after controlling for confounders. The interaction of mistrust and internalizing symptoms at T1 increases the possibility of the onset of paranoia at T2. Therefore, the effect of mistrust on paranoia is more marked when internalizing symptoms are higher. Our results confirm the role of mistrust as a factor involved in the developmental trajectory of paranoia in adolescence, enhanced by the presence of internalizing symptoms. The implications of these results are both theoretical and clinical, as they add developmental information to the cognitive model of paranoia and suggests the assessment and clinical management of mistrust and internalizing symptoms in youth may be useful with the aim of reducing the risk of psychotic experiences.
RESUMO
Paranoia is associated with variation in social behaviour, such as lower inclination to trust others or to behave generously in economic game settings. Such variation may stem, in part, from a reduced tendency to socially identify with others, although previous studies have reported mixed results. We tested whether paranoia involves altered social identification in a pre-registered online study investigating the relationship between a measure of social identification, paranoia, and social behaviours in economic games. We successfully manipulated social identification, but paranoia was associated with slightly increased social identification overall. Neither paranoia nor social identification predicted behaviour in the economic games, and there was no interaction between paranoia and social identification regarding trusting and cooperative behaviours. Our results converge with recent work suggesting that more paranoid individuals may harbour a higher tendency to perceive themselves as having similar beliefs to others. We discuss some key areas for future research to progress understanding in this area.
RESUMO
BACKGROUND: Safety behaviors, both positive (maladaptive coping behavior) and negative (avoidance behavior), are used by people with paranoid delusions to avoid perceived threats. Safety behaviors contribute to the persistence of paranoid delusions by preventing disconfirmation of threat beliefs and may influence other psychiatric symptoms. This study investigated how changes in safety behaviors are related to changes in paranoid ideation, social anxiety, depression, cognitive biases and self-esteem over time. METHODS: This study included 116 patients diagnosed with a psychotic disorder (DSM-IV) and at least moderate levels of paranoid ideations (GTPS >40).The data were collected as part of a multi-center randomized controlled trial where patients were randomized to VR-CBT (n = 58) or treatment as usual (TAU; n = 58). Assessments were completed at baseline (T0), after three months (T3) and after six months (T6). For all variables, change scores between T0 and T3 and T3 and T6 were calculated and Pearson correlations between change scores were computed. RESULTS: A decrease in total safety behavior was related to diminished paranoid ideation, social anxiety, and depression. No significant temporal associations were found between changes in safety behavior and changes in cognitive biases and self-esteem. Similar but less robust results were found for respectively negative safety behavior and positive safety behavior. CONCLUSION: Dropping safety behavior can be specifically targeted in behavioral interventions. Whereas there appears to be a relation with reduction in anxiety, paranoia, and depressive symptoms, changes in safety behavior do not seem to align with changes in cognitive thinking processes.
RESUMO
Positive schizotypy can uniquely predict the development of psychosis with suspiciousness/paranoia having emerged as a key risk factor, pointing to significant worth in reducing this aspect in individuals with high positive schizotypy. Reduced paranoia in the general population following brief online mindfulness training has been previously reported. This study investigated the feasibility of a 40-day online mindfulness-based intervention (MBI) (n = 12) in the individuals with high positive schizotypy characterized by high suspiciousness/paranoia and to estimate its effect on paranoia as compared with an active control condition using reflective journaling (n = 12). The outcome measures were self-reported trait and VR-induced state paranoia, completed at baseline, after 10 days and post-intervention. The feasibility criteria included retention, adherence, engagement, and acceptability. There was 100% retention, excellent adherence to content and engagement, with an average MBI session completion rate of 91%. Acceptability, indexed by a self-rated motivation to continue practice post-intervention, was also high. No MBI effect on trait paranoia was observed; however, the MBI group showed a reduction in the VR-induced state paranoia with a medium-to-large effect (d = 0.63). The findings support conducting larger-scale randomized controlled trials to evaluate the effects of online MBIs on reducing suspiciousness/paranoia to mitigate psychosis risk in individuals with high positive schizotypy.

RESUMO
Background: Paranoia is a spectrum of fear-related experiences that spans diagnostic categories and is influenced by social and cognitive factors. The extent to which social media and other types of media use are associated with paranoia remains unclear. Objective: We aimed to examine associations between media use and paranoia at the within- and between-person levels. Methods: Participants were 409 individuals diagnosed with schizophrenia spectrum or bipolar disorder. Measures included sociodemographic and clinical characteristics at baseline, followed by ecological momentary assessments (EMAs) collected 3 times daily over 30 days. EMA evaluated paranoia and 5 types of media use: social media, television, music, reading or writing, and other internet or computer use. Generalized linear mixed models were used to examine paranoia as a function of each type of media use and vice versa at the within- and between-person levels. Results: Of the 409 participants, the following subgroups reported at least 1 instance of media use: 261 (63.8%) for using social media, 385 (94.1%) for watching TV, 292 (71.4%) for listening to music, 191 (46.7%) for reading or writing, and 280 (68.5%) for other internet or computer use. Gender, ethnoracial groups, educational attainment, and diagnosis of schizophrenia versus bipolar disorder were differentially associated with the likelihood of media use. There was a within-person association between social media use and paranoia: using social media was associated with a subsequent decrease of 5.5% (fold-change 0.945, 95% CI 0.904-0.987) in paranoia. The reverse association, from paranoia to subsequent changes in social media use, was not statistically significant. Other types of media use were not significantly associated with paranoia. Conclusions: This study shows that social media use was associated with a modest decrease in paranoia, perhaps reflecting the clinical benefits of social connection. However, structural disadvantage and individual factors may hamper the accessibility of media activities, and the mental health correlates of media use may further vary as a function of contents and contexts of use.

Paranoia is a common delusion type found in clinical and non-clinical populations. A hierarchical, dimensional model of paranoia in the general population has been proposed, with four categories representing increasing levels of paranoia: interpersonal sensitivity (IP), mistrust (M), ideas of reference (IR), persecutory ideas (PI). What is currently lacking and could provide insights into etiology is a comprehensive clinical characterization of the lower end of the paranoia spectrum, psychological domains that are associated with symptom severity, and how paranoia and its structure fluctuate over time. This study conducted both cross-sectional and longitudinal surveys with 802 participants from the German population assessing paranoia and general psychopathology. Data was collected through Ecological Momentary Assessment (EMA). Several statistical approaches were used including confirmatory factor analysis (CFA), latent class analysis (LCA) and mixed modelling analyses (ME). Paranoid experiences appear to be a common phenomenon that occur in people with and without mental illness. Subjects clustered into four paranoia severity subgroups (IP, M, IR, PI) and showed significant associations in various psychological domains like increased psychiatric symptoms and maladaptive coping. Paranoia fluctuates over time in all four severity subgroups, but the hierarchical subgrouping was stable. Both persecutory ideations and interpersonal sensitivity were significant predictors of paranoia. Findings provide important insights into the architecture of paranoia in the German population by characterizing their hierarchical, dimensional, and dynamic structure and its link to psychopathology.
RESUMO
Paranoid thoughts have been reported in 20-30% of adolescents, and preliminary research has shown that paranoia and psychotic-like experiences have increased during the COVID-19 pandemic. However, previous research has typically used general measures to assess paranoia, rather than those specific to COVID-19, which may overlook particular facets of paranoia related to the pandemic and result in an under-reporting of paranoia prevalence rates during this time. Therefore, this study aimed to examine the psychometric properties of the Pandemic Paranoia Scale for Adolescents (PPS-A), which was adapted from the original scale to be appropriate for younger respondents, and to assess the prevalence of pandemic paranoia among adolescents. Adolescents (N = 462) recruited on Qualtrics from the United States (US) and United Kingdom (UK) completed an online survey consisting of the PPS-A and measures of general paranoia and negative affect. A subset of adolescent's parents (N = 146) also completed an online survey providing dyadic data. Findings showed that the PPS-A shared the same three factor structure as the adult PPS (i.e., persecutory threat, paranoid conspiracy, and interpersonal mistrust) and across participant nationality, race, gender, and mental health diagnosis. It also demonstrated strong psychometric properties. The overall prevalence rate of pandemic-related paranoia among adolescents was 21% and prevalence rates were higher among US participants than UK participants. This study provides the most comprehensive psychometric evaluation of a pandemic paranoia scale designed for adolescents and highlights the continued prevalence of pandemic paranoia in this age-group nearly two years after COVID-19 began.
RESUMO
BACKGROUND: Social factors can play an important role in the development and maintenance of psychosis. Clarifying this relationship is vital for advancing theoretical understanding and development of targeted interventions. Psychosis is increasingly researched with an experience sampling methodology (ESM), which provides an ecologically valid approach, that reduces recall biases. Studies examining momentary associations between social factors and psychosis have not yet been summarised. METHOD: We identified 29 ESM studies investigating associations between social factors and positive psychotic experiences through a pre-registered systematic search of the published literature. RESULTS: Being alone did not predict increase in psychosis; however, appraisals and feelings associated with being alone such as feeling socially disconnected, lonely and unwanted did. Being with familiar company was found to reduce psychosis experiences but feeling stressed by the current company increased psychosis. CONCLUSIONS: While issues with sample size and generalisability mean these results should be interpreted with caution, some putative conclusions can be made. Individuals with psychosis or emerging symptoms should be offered interventions that improve social networks such as peer support, community participation and engagement skills training. These individuals may also benefit from virtual reality or compassion-based interventions which aim to dampen perceived social threat. Moreover, digital interventions which monitor changes in social variables that predict relapse in symptoms would allow early intervention to prevent mental health crises.

Paranoid ideation is a transdiagnostic construct that is associated with social impairment and often occurs in psychotic spectrum disorders. Little research has examined how paranoid ideation is related to social behaviors that underlie social impairment and may ultimately lead to social rejection. It is important to consider that negative symptoms and sleep problems also contribute to social impairment. No research has assessed the unique and combined influence of paranoid ideation, negative symptoms, and sleep problems on social impairment. Therefore, the current study examined how paranoid ideation, negative symptoms, and sleep problems contribute to poorer social skills and social rejection in a transdiagnostic sample of persons with psychosis and community members (N = 112). Assessments included diagnostic and symptom interviews, questionnaires, behavioral ratings of social skill and facial displays of affect, and naive observer reactions utilizing thin-slice methodology. Greater paranoid ideation, negative symptoms, and sleep problems were each related to poorer social skill and more negative reactions from observers. When considered in path analyses, negative symptoms were associated with observer reports of less willingness to interact with participants through poorer social skill. These findings demonstrate the symptom correlates of social rejection and how interpersonal behavior may contribute to social exclusion.

Individuals with schizophrenia show aberrant processing of social cues. In the current study, we (1) compared trustworthiness ratings of faces between patients with schizophrenia and healthy controls, (2) compared pupillary reactivity between patients and controls (3) examined whether trustworthiness judgments in schizophrenia are related to pupil reactivity, (4) and examined associations between trustworthiness judgements and symptom severity, specifically paranoia. Patients with schizophrenia spectrum disorders (N = 48) and healthy controls (N = 33) completed a Trustworthiness Task, during which their pupil size was measured via an eye-tracking device. The mean baseline-corrected pupil size was calculated from 24 pictures of real neutral faces, each presented for 2500â¯ms. Self-reported psychotic experiences were measured by Community Assessment of Psychic Functioning (CAPE-42), and symptom severity was rated by Brief Psychiatric Rating Scale (BPRS). No group differences were found in trustworthiness ratings or pupil reactivity parameters during trustworthiness judgments. Separately, among patients, absolute difference in pupil-size change and dilation after reaching minimum size were related to more severe positive symptoms and self-reported paranoia. Our results did not show social cognitive biases in the stable outpatients with schizophrenia, or the role of pupil reactivity in trustworthiness judgments. Future studies should use longer stimuli for pupillary reactivity and control the type and dosage of utilized antipsychotic medication. Further studies are required to explore relationships in larger and more symptomatic groups of patients.

Aggression is a transdiagnostic behavior that is associated with poor clinical outcomes. As such, it is important to understand factors that contribute to various manifestations of aggressive behavior. Recent research has revealed a subtype of individuals with social anxiety disorder (SAD) who tend to display relatively high amounts of aggression and experience more severe social anxiety and dysfunction compared to individuals in the prototypical SAD group. The current study used a status threat manipulation along with behavioral indices of aggression to examine the impact of paranoia and social anxiety symptom severity on aggression in a sample of undergraduates with social anxiety (Nâ¯=â¯220). Analyses indicated that paranoia uniquely predicted indirect aggression whereas an interaction between social status threat, paranoia, and social anxiety severity uniquely predicted direct aggression. These findings suggest that paranoia may be a particularly important contributor to aggression among individuals with social anxiety.

Following the conjecture made by (Bliznashki and Hristova in Appetite 167:105645, 2021), we test the hypothesis that liberal subjective decision criteria exhibited during a task involving discrimination between random and systematically correlated patterns should be associated with elevated levels of paranoid ideations. Study 1 establishes the proposed association in the presence of several control measures while also demonstrating that the relationship in question is significantly moderated by subjects' working memory spans and tendencies to be overconfident in their judgments. Study 2 provides further evidence that these effects are indeed specific to tasks involving discrimination between random and systematic patterns and that the observed results are not due to some form of (anti) acquiescence bias or other general trends. Certain specifics of the correlation matrices involving cognitive measures significantly related to the paranoia continuum suggest that our results are consistent with the Entropic Brain Hypothesis. Finally, a simulation study employing a Neural Network demonstrates that increased entropy and liberal decision criteria might be connected to each other with said connection being amenable to an interpretation within the Bayesian paradigm.
RESUMO
Beliefs-attitudes toward some state of the environment-guide action selection and should be robust to variability but sensitive to meaningful change. Beliefs about volatility (expectation of change) are associated with paranoia in humans, but the brain regions responsible for volatility beliefs remain unknown. The orbitofrontal cortex (OFC) is central to adaptive behavior, whereas the magnocellular mediodorsal thalamus (MDmc) is essential for arbitrating between perceptions and action policies. We assessed belief updating in a three-choice probabilistic reversal learning task following excitotoxic lesions of the MDmc (n = 3) or OFC (n = 3) and compared performance with that of unoperated monkeys (n = 14). Computational analyses indicated a double dissociation: MDmc, but not OFC, lesions were associated with erratic switching behavior and heightened volatility belief (as in paranoia in humans), whereas OFC, but not MDmc, lesions were associated with increased lose-stay behavior and reward learning rates. Given the consilience across species and models, these results have implications for understanding paranoia.

OBJECTIVES: People with psychosis delay accessing recommended treatments, resulting in poor healthcare outcomes and increased risk of relapse. Means of improving help-seeking and help-acceptance could reduce duration of untreated psychosis (DUP). This study examined the role of attachment style in help-seeking and help-acceptance in psychosis. DESIGN: We used an experimental design to test the effect of attachment imagery priming on help-seeking and help-acceptance intentions, in a sample with self-reported psychosis. The independent variables were attachment imagery condition (secure vs. avoidant) and time (pre- vs. post-prime). The dependent variables were state paranoia, help-seeking intentions and help-acceptance intentions. METHODS: We used an online research platform to recruit people with psychosis (n = 61). Participants were randomly allocated to the secure or avoidant attachment priming condition. All completed measures of state paranoia, help-seeking, and help-acceptance, before and after priming. RESULTS: In comparison with the avoidant condition, secure attachment imagery resulted in reduced paranoia and increased help-seeking and acceptance intentions, all with large effect sizes. CONCLUSIONS: This is the first study to use an experimental design to assess the role of attachment style in help-seeking and help-acceptance in a clinical sample. Attachment style is causally linked to behavioural intentions that contribute to DUP. Clinicians should assess attachment and help-seeking and acceptance, highlight these in formulation, and prioritise in treatment planning. Interventions that enhance help-seeking and acceptance could improve access to recommended treatments and reduce DUP.

BACKGROUND: Virtual Reality cognitive behavioral therapy (VR-CBT) has proven to be an effective treatment method for paranoia and anxiety in psychosis. However, it is unknown, which individuals benefit most from VR-CBT. Previous studies examined factors affecting the treatment effect of regular CBTp, including illness duration, paranoia, depression, and pre-therapy avoidance behaviors, but results are inconsistent. The study aims to investigate the factors that influence the effectiveness of VR-CBT. METHODS: A total of 95 participants with a psychotic disorder and at least moderate paranoia (GTPS >40) were included in this explorative study. Data were collected as part of a multicenter randomized controlled trial in which participants were assigned to VR-CBT or treatment as usual (TAU). The VR-CBT group received 16 sessions of individual treatment. A moderator analysis was conducted to examine the influence of baseline demographic (age, gender, and education level) and clinical characteristics (duration of illness, paranoia, anxiety, depression, safety behavior, self-esteem, and social functioning) on treatment effects of paranoia and anxiety as measured with questionnaires and the experience sampling method (ESM) directly after treatment (12 weeks after baseline). RESULTS: More use of safety behavior at baseline resulted in greater benefits of VR-CBT on paranoid ideation and ESM paranoia. A higher age was associated with greater benefits of VR-CBT on social anxiety but not paranoia outcomes. There was no consistent evidence of moderation by any of the other sociodemographic or clinical variables for paranoid ideation and social anxiety. CONCLUSIONS: Our findings suggest that a diverse spectrum of patients, with different backgrounds and symptom severity may be able to benefit from VR-CBT. VR-CBT can be recommended to a broad spectrum of patients with psychotic disorders, and particularly those with high levels of safety behaviors, including severe avoidance, seem to benefit more.
RESUMO
The purpose of the present article is to consider schizophrenia-the very idea-from the perspective of phenomenological psychopathology, with special attention to the problematic nature of the diagnostic concept as well as to the prospect and challenges inherent in focusing on subjective experience. First, we address historical and philosophical topics relevant to the legitimacy of diagnostic categorization-in general and regarding "schizophrenia" in particular. William James's pragmatist approach to categorization is discussed. Then we offer a version of the well-known basic-self or ipseity-disturbance model (IDM) of schizophrenia, but in a significantly revised form (IDMrevised). The revised model better acknowledges the diverse and even seemingly contradictory nature of schizophrenic symptoms while, at the same time, interpreting these in a more unitary fashion via the key concept of hyperreflexivity-a form of exaggerated self-awareness that tends to undermine normal world-directedness and the stability of self-experience. Particular attention is paid to forms of exaggerated "self-presence" that are sometimes neglected yet imbue classically schizophrenic experiences involving subjectivism or quasi-solipsism and/or all-inclusive or ontological forms of paranoia. We focus on the distinctively paradoxical nature of schizophrenic symptomatology. In concluding we consider precursors in the work of Klaus Conrad, Kimura Bin and Henri Grivois. Finally we defend the concept of schizophrenia by considering its distinctive way of altering certain core aspects of the human condition itself.

Introduction: Studies have consistently demonstrated increased stress sensitivity in individuals with psychosis. Since stress sensitivity may play a role in the onset and maintenance of psychosis, this could potentially be a promising target for treatment. The current study was the first to investigate whether reactivity to and recovery from daily-life stressors in psychosis change in response to treatment, namely virtual-reality-based cognitive behavioral therapy (VR-CBT). Methods: 116 patients were randomized to either VR-CBT or the waiting list control group (WL). Pre-treatment and post-treatment participants completed a diary ten times a day during six to ten days. Multilevel analyses were used to model the time-lagged effects of daily stressful events on negative affect (NA) and paranoia symptoms to examine reactivity and recovery. Results: There was a significant difference in NA reactivity. VR-CBT showed higher NA at post-treatment compared to pre-treatment than WL (bpre=0.14; bpost=0.19 vs bpre=0.18; bpost=0.14). There was a significant difference in NA recovery and paranoia recovery between the groups at lag 1: VR-CBT showed relatively lower negative affect (bpre=0.07; bpost=-0.06) and paranoia (bpre= 0.08; bpost=-0.10) at post-treatment compared to pre-treatment than WL (bpre=0.08; bpost=0.08; bpre=0.04; bpost=0.03). Conclusion: Negative affect and paranoia recovery improved in response to treatment. Increased NA reactivity may be explained by a decrease in safety behavior in the VR-CBT group. The discrepancy between reactivity and recovery findings may be explained by the inhibitory learning theory that suggests that an original threat reaction may not erase but can be inhibited as a consequence of exposure therapy.
RESUMO
Given the culturally diverse landscape of mental healthcare and research, ensuring that our psychological constructs are measured equivalently across diverse populations is critical. One construct for which there is significant potential for inequitable assessment is paranoia, a prominent feature in psychotic disorders that can also be driven by culture and racial marginalization. This study examined measurement invariance-an analytic technique to rigorously investigate whether a given construct is being measured similarly across groups-of the Revised-Green Paranoid Thought Scale (R-GPTS; Freeman et al., 2021) across Black and White Americans in the general population. Racial group differences in self-reported paranoia were also examined. The analytic sample consisted of 480 non-Hispanic White and 459 non-Hispanic Black Americans. Analyses demonstrated full invariance (i.e., configural, metric, and scalar invariance) of the R-GPTS across groups, indicating that the R-GPTS appropriately captures self-reported paranoia between Black and White Americans. Accordingly, it is reasonable to compare group endorsement: Black participants endorsed significantly higher scores on both the ideas of reference and ideas of persecution subscales of the R-GPTS (Mean ± SD = 10.91 ± 7.12 versus 8.21 ± 7.17 and Mean ± SD = 10.18 ± 10.03 versus 6.35 ± 8.35, for these subscales respectively). Generalized linear modeling revealed that race remained a large and statistically significant predictor of R-GPTS total score (ß = -0.38756, p < 0.001) after controlling for relevant demographic factors (e.g., sex, age). This study addresses a critical gap within the existing literature as it establishes that elevations in paranoia exhibited by Black Americans in the R-GPTS reflect actual differences between groups rather than measurement artifacts.

The COVID-19 pandemic contributed to worsening mental health across the globe. The pandemic may have been especially impactful on those experiencing heightened psychosis spectrum symptomatology given greater pre-pandemic social isolation and increased vulnerability to stress. Yet, few studies exploring the impact of the COVID-19 pandemic on perceptions of social relationships and mental health have sampled individuals high in psychosis spectrum symptomatology, including those with psychosis spectrum disorders. Utilizing a mixed transdiagnostic community sample enriched for psychotic spectrum disorders, this longitudinal study investigated whether perceptions of social relationships and psychiatric symptoms changed during the COVID-19 pandemic, whether pandemic-related impacts were associated with social perceptions and symptomatology, and whether paranoid ideation was related to perceptions of the government response to the COVID-19 pandemic. Pandemic impacts were not uniform, with participants reporting a range of adverse impacts including poorer health-related behaviors, difficulties fulfilling basic needs, and medical related challenges. Results indicated that compared to pre-pandemic assessments, perceived rejection and hostility increased during the COVID-19 pandemic. Participants who experienced more pandemic-related impacts reported less social support, more social distress, greater negative affect, and greater paranoid ideation. Paranoid ideation was related to more negative perceptions of the government's response to the pandemic. These findings demonstrate the importance of assessing individual differences in pandemic-related impacts and the clinical consequences of such impacts. Results also suggest that those high in paranoid ideation may be reluctant to engage in government recommended protective health behaviors to limit the spread of COVID-19.
