The Impact of Irrational Beliefs on Paranoid Thoughts

Digitally Enhanced Psychological Assessment and Treatment of Paranoia: A Systematic Review

BACKGROUND

Paranoia is relatively common but can lead to significant distress, impairment and need for care. Digital technologies offer a valuable extension to service provision and are increasingly being integrated into healthcare. This systematic review evaluated feasibility, acceptability, and effectiveness of digitally enhanced psychological assessments and treatments for paranoia across the paranoia continuum (PROSPERO: CRD42023393257).

METHODS

Databases PsychINFO, EMBASE, MEDLINE and Web of Science were searched until 12 June 2023; the Effective Public Health Practice Project (EPHPP) quality assessment tool evaluated studies; and a narrative synthesis was conducted.

RESULTS

Twenty-seven studies met inclusion criteria (n = 3457, 23 assessment and 4 treatment, 2005-2023, most in Europe). Technologies included virtual reality (VR, n = 23), experience sampling methodology (ESM, n = 2), an app (n = 1) and a combination of VR and ESM (n = 1). Assessments involved monitoring paranoia under various virtual conditions or in everyday life. Treatments were generally integrated with Cognitive Behaviour Therapy (CBT), which involved using VR to test out threat beliefs and drop safety behaviours or using an app to support slowing down paranoid thinking. EPHPP ratings were strong (n = 8), moderate (n = 12) and weak (n = 7).

CONCLUSIONS

Digitally enhanced assessments and treatments showed promising acceptability, feasibility and treatment effectiveness. Limitations of studies include small sample sizes, lack of comparison groups and long-term data and limited randomised controlled trials. Results support the potential future integration of VR in the assessment of paranoia and show promise for treatments such as CBT, although further clinical trials are required. Investigation of other technologies is limited.

Gene-Environment Interactions in Irrational Beliefs: The Roles of Childhood Adversity and Multiple Candidate Genes

Cognitive behavioral therapy is based on the view that maladaptive thinking is the causal mechanism of mental disorders. While this view is supported by extensive evidence, very limited work has addressed the factors that contribute to the development of maladaptive thinking. The present study aimed to uncover interactions between childhood maltreatment and multiple genetic differences in irrational beliefs. Childhood maltreatment and irrational beliefs were assessed using multiple self-report instruments in a sample of healthy volunteers (N = 452). Eighteen single-nucleotide polymorphisms were genotyped in six candidate genes related to neurotransmitter function (COMT; SLC6A4; OXTR), neurotrophic factors (BDNF), and the hypothalamic-pituitary-adrenal axis (NR3C1; CRHR1). Gene-environment interactions (G×E) were first explored in models that employed one measure of childhood maltreatment and one measure of irrational beliefs. These effects were then followed up in models in which either the childhood maltreatment measure, the irrational belief measure, or both were substituted by parallel measures. Consistent results across models indicated that childhood maltreatment was positively associated with irrational beliefs, and these relations were significantly influenced by COMT rs165774 and OXTR rs53576. These results remain preliminary until independent replication, but they represent the best available evidence to date on G×E in a fundamental mechanism of psychopathology.

Experimental studies of paranoid thinking in clinical and nonclinical populations: a systematic review and meta-analysis

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

Childhood Adversity, Resilience, and Paranoia During the COVID-19 Outbreak. The Mediating Role of Irrational Beliefs and Affective Disturbance

Childhood adversity (CA) and resilience may impact on paranoia, but mechanisms underlying these associations are largely unknown. In this study, we investigated two potential candidates: irrational beliefs and affective disturbance. Moreover, we investigated the potential moderating role of COVID-19 perceived stress in these associations. A community sample (N = 419, m age = 27.32 years, SD = 8.98; 88.10% females) completed self-report measures. Results indicated that paranoia was significantly associated with CA and resilience (p < .05), and both irrational beliefs and affective disturbance (i.e., depressive and anxiety symptoms) mediated the associations between CA and paranoia. Moreover, depressive and anxiety symptoms partially explained the mediating role of irrational beliefs. These predictive models explained up to 23.52% of variance in paranoia (F(3,415) = 42.536, p < .001). Findings on resilience and paranoia replicated these results, and COVID-19 perceived stress moderated the association between resilience and ideas of persecution. Overall, these findings underscore the importance of irrational beliefs, depressive and anxiety symptoms in high CA or low resilience individuals experiencing paranoia.

Mobile shoppers' response to Covid-19 phobia, pessimism and smartphone addiction: Does social influence matter?

Because of the Covid-19 pandemic, there has been a variety of changes identified in customers' shopping behaviours, and development of new practices as a response to the crisis. The purpose of this research is to examine the effects of Covid-19 phobia, and news exposure on individuals' psychological states, and their resulting mobile shopping behaviour. Relying upon the Activate, Belief and Consequences (ABC) model of the Cognitive-Behaviour Theory, this research applies the partial least square structural modelling (PLS-SEM) methodology for analysing the data from 302 mobile shoppers from India. The results confirm that Covid-19 phobia and Covid-19 news exposure are substantial determinants of consumers' smartphone addictive use and pessimism, which in turn affect mobile shopping frequency. Additionally, social influence is found to play a vital role in moderating mobile shopping frequency for individuals, who experience smartphone addiction. The current study is a pioneering effort to examine the influence of Covid-19-induced phobia on consumers' psychological states and their subsequent impact on their mobile shopping frequency. The study provides several contributions to theory and practice within the areas of technology use and mobile shopping in particular.

Feasibility and clinical utility of a transdiagnostic Internet-delivered rational emotive and behavioral intervention for adolescents with anxiety and depressive disorders

BACKGROUND

Transdiagnostic interventions delivered for children and adolescents show promising results. In order to increase access to treatment, recent developments in technology have led to alternatives to face-to-face interventions. Transdiagnostic Internet-delivered interventions can be effective for adult anxiety and depressive disorders, but research is more limited regarding the efficacy of such treatments for young populations diagnosed with anxiety and or depressive disorders.

OBJECTIVE

This study aims to investigate the feasibility and clinical utility of a transdiagnostic Internet-delivered intervention based on Rational emotive behavior therapy for adolescents diagnosed with anxiety and depressive disorders.

METHODS

We tested the preliminary efficacy of a six-week intervention in an open trial, pre-post design.

RESULTS

Our results suggest that the intervention is feasible and can be included as a treatment for adolescents with anxiety and depressive disorders, being associated with moderate to large pre-post effect sizes on self-reported anxiety and depressive symptoms, as well as on negative patterns of thinking and knowledge acquisition. Satisfaction with the intervention was high.

CONCLUSIONS

Transdiagnostic Internet-delivered interventions for adolescents with anxiety and depressive symptoms are feasible. Future testing of the efficacy of such interventions in randomized controlled trials should be conducted.

Paranoia and negative schema about the self and others: A systematic review and meta-analysis

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