Examining the relationships between cognition and auditory hallucinations: A systematic review.

OBJECTIVE: Auditory hallucinations (hearing voices) have been associated with a range of altered cognitive functions, pertaining to signal detection, source-monitoring, memory, inhibition and language processes. Yet, empirical results are inconsistent. Despite this, several theoretical models of auditory hallucinations persist, alongside increasing emphasis on the utility of a multidimensional framework. Thus, clarification of current evidence across the broad scope of proposed mechanisms is warranted. METHOD: A systematic search of the Web of Science, PubMed and Scopus databases was conducted. Records were screened to confirm the use of an objective behavioural cognitive task, and valid measurement of hallucinations specific to the auditory modality. RESULTS: Auditory hallucinations were primarily associated with difficulties in perceptual decision-making (i.e. reduced sensitivity/accuracy for signal-noise discrimination; liberal responding to ambiguity), source-monitoring (i.e. self-other and temporal context confusion), working memory and language function (i.e. reduced verbal fluency). Mixed or limited support was observed for perceptual feature discrimination, imagery vividness/illusion susceptibility, source-monitoring for stimulus form and spatial context, recognition and recall memory, executive functions (e.g. attention, inhibition), emotion processing and language comprehension/hemispheric organisation. CONCLUSIONS: Findings were considered within predictive coding and self-monitoring frameworks. Of concern was the portion of studies which - despite offering auditory-hallucination-specific aims and inferences - employed modality-general measures, and/or diagnostic-based contrasts with psychologically healthy individuals. This review highlights disparities within the literature between theoretical conceptualisations of auditory hallucinations and the body of rigorous empirical evidence supporting such inferences. Future cognitive investigations, beyond the schizophrenia-spectrum, which explicitly define and measure the timeframe and sensory modality of hallucinations, are recommended.

Exploring the cognitive profiles related to unimodal auditory versus multisensory hallucinations in schizophrenia-spectrum disorders.

INTRODUCTION: Hallucinations can be experienced across multiple sensory modalities, but psychiatric studies investigating the cognitive mechanisms of hallucinations have been somewhat restricted to the auditory domain. This study explored the cognitive profiles of individuals experiencing multisensory hallucinations (MH) in schizophrenia-spectrum disorders (SSD) and compared these to those experiencing unimodal auditory hallucinations (AH) or no hallucinations (NH). METHODS: Participants included SSD patients (n = 119) stratified by current hallucination status (NH, AH, MH) and nonclinical controls (NCs; n = 113). Group performance was compared across several cognitive domains: speed of processing, attention, working memory, verbal learning, visual learning, reasoning and problem-solving, social cognition, and inhibition. RESULTS: The clinical groups performed worse than NCs but differences between the clinical groups were not evident across most cognitive domains. Exploratory analyses revealed that the MH group was more impaired on the visual learning task compared to the NH (but not AH) group. CONCLUSIONS: Preliminary results suggest that impaired visual learning may be related to MH. This could be attributed to the presence of visual hallucinations (VH), or greater psychopathology, in this group. However, replication is needed, as well as the investigation of other potential cognitive mechanisms of MH.

Representation of Voice Hearing Groups by French Mental Health Professionals.

Hearing voices groups (HVGs) are an alternative way of treating acoustic-verbal hallucinations. Although they have been developing in France for the last decade, they have lagged behind their international expansion. The representations that circulate about their functioning and their effects are likely to influence the referral to these groups by mental health professionals. We created and used a questionnaire to survey mental health professionals' representations of voice hearing groups. We surveyed 79 French health professionals using a questionnaire with 19 closed items. 7 additional items allowed us to specify the professional status and familiarity of the participants with the HVGs. Professionals generally shared positive representations of HVGs but had very approximate knowledge of them. The subgroup of the most familiar professionals (N = 45) differed significantly on 7 items from the subgroup of non-familiars (N = 35). HVGs are represented as one medical offer among others, of little clinical use and indicated only for psychotic voice-hearing patients, which seems to be a misunderstanding in every case. However, our study also shows that these opinions evolve with the degree of familiarity with HVGs. Certain representations need to be corrected so that quality information can be circulated about HVGs and improve their integration into their ecosystem.

Mediators of negative content and voice-related distress in a diverse sample of clinical and non-clinical voice-hearers.

OBJECTIVES: Negative content in hearing voices (i.e., auditory verbal hallucinations) has been associated with adverse clinical outcomes including voice-related distress. Voice appraisals and responding mindfully to voices are theorized to reduce voice-related distress. This study aimed in examine mediators of the negative content voice-related distress relationship in clinical (those who recently received input from mental health services) and non-clinical voice-hearers. METHODS: One hundred and twenty-one adults (71.9% female; 35.5% mixed or non-white ethnic background) who hear voices were recruited online and completed self-report measures of negative content of voices, voice-related distress, mindfulness of voices, interpretation of loss of control, thought suppression and intrusion. RESULTS: Clinical voice-hearers had significantly higher levels of negative content, voice-related distress and interpretation of loss of control than non-clinical voice-hearers. A mindful approach to voices and interpretation of loss of control mediated the relationship between negative content and voice-related distress across the whole sample. Thought suppression and intrusion did not mediate the relationship. CONCLUSIONS: The results support the use of mindfulness-based psychological intervention to reduce voice-related distress. Further development of valid and reliable measures specifically relating to constructs of voice content, voice-related distress and voice suppression will support further research in this area.

Strategies for the Management of Voices Shared in a Brazilian Hearing Voices Group.

Hearing Voices peer support groups allow people to construct understandings of their voices. The groups focus on supporting voice hearers in reducing distress associated with voices through an array of strategies. This study sought to describe the voice management strategies shared in a hearing voices peer support group within a Brazilian public mental health service. In this qualitative study we recorded 10 group meetings. Transcripts were coded and analyzed using thematic analysis. The findings indicated five themes, described as: (1) strategies used to avoid distressing experiences; (2) strategies for managing the voices; (3) strategies for seeking social support; (4) strategies for creating a sense of belonging in the community; and (5) strategies related to spirituality and religiosity. These strategies appear to be essential in helping voice hearers feel less alone, reducing the amount of distress associated with hearing voices, and developing coping strategies. These groups provide people who hear voices with the opportunity to share their stories with peers in a group setting, construct new understandings about the experience, and learn strategies for managing their voices. Accordingly, there are great possibilities for the use of these groups within mental health services throughout Latin America.

[Pilot study of Experience Focused Counselling by nurses with people who hear voices: Evaluation of the implementation of the study protocol]. / Pilotstudie zu Erfahrungsfokussierter Beratung durch Pflegende bei Menschen, die Stimmen hören.

Pilot study of Experience Focused Counselling by nurses with people who hear voices: Evaluation of the implementation of the study protocol Abstract: Background: Hearing voices and the treatment and support of people who hear voices and are distressed by the experience are defined differently in psychiatry. In contrast to the medical approach to define and treat voices as symptoms of a disease, the EFC counselling approach developed with voice-hearers focuses on non-pathologizing acceptance and a constructive relationship to voices. Mental health nurses with their focus on everyday life are predestined for the dissemination and application of alternative therapeutic approaches in practice. Aim: The aim was to evaluate the study protocol as part of a pilot study regarding its suitability for a larger trial. Method: The multi centre pilot study had a single-blind randomised controlled design. The intervention consisted of EFC counselling by nurses with people who hear voices. The control group received Treatment As Usual (TAU). The suitability of the study design was evaluated in terms of recruitment, burden on study participants, suitability of assessment tools, the application of EFC counselling and the use of study nurses. Results: As planned 21 participants could be included in the study within fifteen months across the two study sites. Overall, the participants rated the study as not very burdensome and the intervention as helpful. The application of EFC by the nurses as well as the use of study nurses was assessed as good and suitable respectively. Discussion: The evaluation of the study protocol shows that with minor adjustments it is suitable for conducting a larger study.

Adaptation of a Hearing Voices Group Facilitation Training for VA Stakeholders.

The Hearing Voices (HV) Movement promotes diverse understandings of voice-hearing and seeing visions, which mental health professionals commonly refer to as 'auditory hallucinations,' 'schizophrenia,' or 'psychosis.' Central to this movement are peer support groups through which attendees connect with others who have similar experiences. This paper describes an adaptation of a Hearing Voices group facilitation training at VA Greater Los Angeles (VAGLA) and discusses training modifications, along with trainee perceptions and implementation and intervention outcomes. This is a first step towards adapting HV-inspired groups to VA systems of care. Data collection involved surveys of trainees (n = 18) and field notes throughout the 24 h online training. Findings indicate high acceptability and appropriateness of the training and high feasibility in implementation, suggesting the training was well-adapted to VAGLA. This research contributes to global efforts to integrate the Hearing Voices approach in diverse settings and increase awareness about its benefits among providers.

A cross-sectional study of auditory verbal hallucinations experienced by people with a diagnosis of borderline personality disorder.

BACKGROUND: The presence of auditory verbal hallucinations (AVHs) does not currently feature in the main diagnostic criteria for borderline personality disorder (BPD). However, there is accumulating evidence that a high proportion of BPD patients report longstanding and frequent AVHs which constitute a significant risk factor for suicide plans and attempts, and hospitalization. AIM: This study addressed questions about the validity and phenomenology of AVHs in the context of BPD. The longer-term aim is to facilitate the development and translation of treatment approaches to address the unmet need of this population. METHOD: This was a cross-sectional study, combining phenomenological and psychological assessments administered in person and online. We explored the experiences of 48 patients with a diagnosis of BPD who were hearing AVHs. RESULTS: Participants gave 'consistent' reports on the measure of AVH phenomenology, suggesting that these experiences were legitimate. Similar to AVHs in a psychosis context, AVHs were experienced as distressing and appraised as persecutory. AVHs were found to be weakly associated with BPD symptoms. AVHs were also rated highly as a treatment priority by the majority of participants. CONCLUSION: The findings suggest that AVH is a legitimate and distressing symptom of BPD and a treatment priority for some patients. The relative independence of AVHs from other BPD symptoms and emotional states suggests that psychological treatment may need to be targeted specifically at the symptom of AVHs. This treatment could be adapted from cognitive behaviour therapy, the psychological intervention that is recommended for the treatment of AVHs in the context of psychosis.

The role of self-compassion on the relationship between trauma and hearing voices.

Traumatic life events are associated with increased risk of hearing voices and posttraumatic stress (PTS) symptoms have been implicated in this relationship. Studies indicate that increased self-compassion is associated with reduced PTS symptoms and voice-distress. The present study sought to examine whether self-compassion moderated the relationship between PTS symptoms and voice-distress. Self-report and clinician-administered questionnaires were used to measure self-compassion, PTS symptom severity, voice-frequency, and voice-distress in 62 trauma-affected voice-hearers who presented to a community voice-hearing clinic. Correlation analyses revealed that PTS symptom severity was positively correlated with voice-distress, but not voice-frequency, and that self-compassion was negatively correlated with voice-distress and PTS symptom severity. While self-compassion did not moderate the relationship between PTS symptom severity and voice-distress, it was associated with a significant reduction in voice-distress, at all levels of PTS symptom severity. Preliminary findings suggest self-compassion may play an important role in reducing voice-distress and thus warrant further consideration of self-compassion as a target in treatment for help-seeking voice-hearers.

Brief coping strategy enhancement for the treatment of distressing voices in the context of borderline personality disorder: A comparison with outcomes in the context of psychosis.

BACKGROUND: Voice hearing in the context of Borderline Personality Disorder (BPD) has traditionally been regarded as transient and an experience that lacks legitimacy. Consequently, there are no evidence-based treatments for the voices reported by BPD patients. Contrary to the traditional view, there is a growing literature suggesting that voice hearing in the context of BPD can be an enduring and distressing experience which shares similarities with voice hearing in the context of psychosis. Given these similarities, the aim of this study was to explore whether brief Coping Strategy Enhancement developed in the context of psychosis can be used to treat distressing voice hearing in the context of BPD. METHOD: This was a service evaluation carried out in a specialist NHS service delivering psychological therapies for distressing voices. Patients with either a BPD (n = 46) or a psychosis diagnosis (n = 125) received four sessions of Coping Strategy Enhancement (CSE). The primary outcome was voice-related distress. The pre-post outcomes for BPD patients were explored and compared with those achieved by the psychosis patients. RESULTS: Both the BPD and psychosis groups experienced a significant reduction in voice-related distress after CSE compared with baseline. The interaction between diagnosis group and time was small and statistically non-significant. CONCLUSION: These findings suggest a brief CSE intervention developed in the context of psychosis can be an effective starting point in the treatment of distressing voice hearing in the context of BPD. Such interventions have the potential to be integrated into broader BPD treatment programmes for those who hear voices.

Young people's narratives of hearing voices: Systemic influences and conceptual challenges.

Despite the prevalence of voice hearing in childhood and adolescence, little qualitative research has been undertaken with young people directly to advance phenomenological and aetiological insights into their experiences and interpretations. Consequently, the researchers sought demographic, contextual, and qualitative data from 74 young people from eleven countries, aged 13-18 years (28% = male; 61% = female; 21% = Transgender and Gender Non-Binary [TGNB]), who self-identified as hearing voices. A Foucauldian-informed narrative analysis yielded four analytic chapters, offering novel perspectives into individual, relational, systemic, and cultural interpretative narratives surrounding multisensory and multi-self voice hearing. Overall, young people reported heterogenous experiences of voice hearing and associated sensory experiences, and most participants reported voice hearing beginning between ages 8 and 11. Further, the emotions felt by the child, as well as reactions displayed by people around the child in relation to the voices, influenced voice-related distress and the nature of the voices in a triadic relationship. A continuum of multisensory features of voice content, nature, and relational significance is tentatively proposed to capture the breadth and depth of voice hearing for adolescents to offer a possible framework for future study and intervention design. Specifically, participants described that voice-related distress could be exacerbated by observed anxiety or internalized stigma about voice hearing, social isolation, and attribution to illness. These findings suggest that we may need to reconsider how the experience of hearing voices in childhood influences their relationships and how relationships influence the voice hearing experience. Further, young people seem to have a broad understanding of what the term "hearing voices" means, which could inform how researchers and practitioners work with this group of young people. Finally, participants described benefitting from multisensory coping strategies, such as imagery and meditation, which could offer important considerations for tailoring therapeutic interventions for adolescent voice hearers.

Whispers, echoes, friends and fears: forms and functions of voice-hearing in adolescence.

BACKGROUND: Despite the high prevalence of voice-hearing in childhood, research with adolescents aged under 16 years is scarce. Theoretical connections between clinical and developmental conceptualizations of voice-hearing are limited, resulting in missed opportunities to explore unusual sensory experiences with young people. METHODS: Demographic, contextual and qualitative data were collected through a web-based survey with 68 adolescents (M = 14.91; SD = 2.77) from Australia, Canada, Ireland, New Zealand, Spain, the United Kingdom and United States of America. A Foucauldian-informed narrative analysis captured phenomenologically meaningful individual accounts and systemically informed narratives. Analytic layers attended specifically to the form and function of voices, including relational, protective, distressing and nuanced experiences, offering new insights into individual, systemic and cultural interpretative narratives surrounding voice-hearing to inform research, policy and tailored support. RESULTS: The average self-reported age of onset of voices was 9 years, 5 months. Reciprocal relationships with pleasant voices were evidenced through the narratives and characterization of voices, while distressing voices were described without reciprocity and the voices held greater power over the young person. Positive aspects of negative voices were discussed and are illustrated with a continuum matrix reflecting interpretation and related affect. CONCLUSIONS: Voice-hearing is a heterogeneous and often complex relational experience for young people, with structural inequalities, relational traumas and social isolation attributed causes of voice-hearing. Developing personal meaning-making mitigated voice-related distress through contextualizing the origin of the voices in past experiences, without attribution to mental illness. Recommendations are proposed for assessment, formulation and relational interventions that recognize the potential impact of the voice-child-other relationship upon psychosocial functioning and wellbeing.

"I'm Not Telling an Illness Story. I'm Telling a Story of Opportunity": Making Sense of Voice Hearing Experiences.

This study aimed to explore how adults with lived experiences of voice hearing, who have participated in hearing voices groups based on approaches of the Hearing Voices Movement, understand their voice hearing experiences (VHE). A phenomenological approach guided the study design. In-depth semi-structured interviews were conducted with five participants who attended a hearing voices group. Participants experienced a journey of understanding VHE. The overarching theme 'tension and recalibration' permeated five themes: beliefs about voices; navigating the relationship with my voices; learning to live with my voices; rediscovering myself with my voices; and, influences to understanding my voices. This study highlights how voice hearers' understanding can evolve over time and throughout phases of recovery. Implications regarding intervention to support individuals to explore VHE are discussed.

Assessing the clinical significance of treatment outcomes for distressing voices in routine clinical practice.

Determining reliable and clinically significant change is central to evidence-based practice yet rarely used in routine clinical settings. This paper illustrates these methods in the context of an evaluation of cognitive behaviour therapy for distressing auditory hallucinations ("voices"). We used data from a clinical sample attending Perth Voices Clinic, a transdiagnostic outpatient service for distressing voices, and a previously published reference sample of healthy voice hearers. Our outcomes on the primary measure of voice distress, derived from a previous factor analysis of the Psychotic Symptom Rating Scale-Auditory Hallucinations subscale, showed that 62.9% of clients were classified as Recovered/Improved, 35.5% were classified as Unchanged, and 0.02% were classified as Deteriorated. Partial support for the validity of these classifications was obtained from the scores on the Depression, Anxiety, Stress Scales (Lovibond & Lovibond, 1995) but not on the Social and Occupational Functional Assessment Scale (Goldman et al., 1992). Clients classified as Recovered showed better emotional functioning on the Depression, Anxiety, Stress Scales compared with those who did not make a clinically significant change in voice distress. A tool is provided to assist practitioners to evaluate whether individual clients have benefited from therapy for distressing voices or not, which can be used to guide future treatment decisions (https://osf.io/gd9e5/).

Do eating disorder voice characteristics predict treatment outcomes in anorexia nervosa? A pilot study.

Individuals with anorexia nervosa often describe experiencing an internal "voice" of their disorder, which previous research has associated with multiple dimensions of eating pathology. This pilot study examined whether eating disorder measures use invoice characteristics at the outset of outpatient therapy predicted changes in disordered eating over the course of treatment. Participants were 14 individuals meeting ICD-10 criteria for anorexia nervosa. Participants completed measures relating to the severity of disordered eating and voice-related characteristics (perceived voice power and metacognitive appraisals about its nature) at the start and end of therapy. Results indicated that the perceived power of the eating disorder was reduced over the course of outpatient therapy, although its other characteristics remained stable. Greater levels of voice power, omnipotence and benevolence at the outset of therapy were related to greater improvements in eating attitudes. No voice-related characteristics were associated with changes in weight. These findings suggest that voice-related appraisals do not obstruct the effectiveness of outpatient therapies for anorexia nervosa. Further studies are needed to ratify these preliminary findings.

The Phenomenon of "Hearing Voices": Not Just Psychotic Hallucinations-A Psychological Literature Review and a Reflection on Clinical and Social Health.

The phenomenon of hearing voices is currently a much-discussed topic, both in the field of research and in the field of care services. The majority of people who report "hearing voices" do not subsequently receive services or receive a diagnosis of psychopathology. This topic raises questions for professionals in the health field about the lack of tools that can help illuminate the phenomenon. The purposes of this work are (a) to highlight the psychological studies that approach the phenomenon in a non-psychopathological way and (b) to determine which concepts could aid the comprehension of the phenomenon. The method consists of a systematic review of the literature that characterizes the phenomenon of hearing voices from a non-pathological perspective. The literature offers different theoretical approaches to interpret the phenomenon in a way that is not necessarily pathological and presents new tools for examining the phenomenon. For example, a few studies state that it is possible to coexist with voices, while others indicate that it is necessary to know how to manage voices. We highlighted and discussed several concepts that can support doctors, psychiatrists and practitioners in understanding "hearer" patients, particularly attention to the context of belonging, attention to language, and the role of the sense-making process.

Mindfulness of voices, self-compassion, and secure attachment in relation to the experience of hearing voices.

OBJECTIVES: Developing compassion towards oneself has been linked to improvement in many areas of psychological well-being, including psychosis. Furthermore, developing a non-judgemental, accepting way of relating to voices is associated with lower levels of distress for people who hear voices. These factors have also been associated with secure attachment. This study explores associations between the constructs of mindfulness of voices, self-compassion, and distress from hearing voices and how secure attachment style related to each of these variables. DESIGN: Cross-sectional online. METHOD: One hundred and twenty-eight people (73% female; Mage  = 37.5; 87.5% Caucasian) who currently hear voices completed the Self-Compassion Scale, Southampton Mindfulness of Voices Questionnaire, Relationships Questionnaire, and Hamilton Programme for Schizophrenia Voices Questionnaire. RESULTS: Results showed that mindfulness of voices mediated the relationship between self-compassion and severity of voices, and self-compassion mediated the relationship between mindfulness of voices and severity of voices. Self-compassion and mindfulness of voices were significantly positively correlated with each other and negatively correlated with distress and severity of voices. CONCLUSION: Mindful relation to voices and self-compassion are associated with reduced distress and severity of voices, which supports the proposed potential benefits of mindful relating to voices and self-compassion as therapeutic skills for people experiencing distress by voice hearing. PRACTITIONER POINTS: Greater self-compassion and mindfulness of voices were significantly associated with less distress from voices. These findings support theory underlining compassionate mind training. Mindfulness of voices mediated the relationship between self-compassion and distress from voices, indicating a synergistic relationship between the constructs. Although the current findings do not give a direction of causation, consideration is given to the potential impact of mindful and compassionate approaches to voices.

Experience Focussed Counselling with Voice Hearers: Towards a Trans-diagnostic Key to Understanding Past and Current Distress-A Thematic Enquiry.

As it is increasingly evident that distressing voices can be linked to traumatic events across diagnoses, there is a need for new transdiagnostic interventions for persons with voice hearing related distress. Twenty-five interviews with voice hearers and mental health professionals explored the trans-diagnostic suitability of Experience Focussed Counselling (EFC) compared to Treatment As Usual. An Applied Thematic Analysis was used. Themes identified were: intervention applicability; impact of regular treatment before study; impact of EFC process; process of working with voices; impact of regular treatment during study; views on treatment or approach. The EFC focus was considered helpful across diagnoses. The findings support EFC as a transdiagnostic intervention.

Understanding clinician attitudes towards implementation of guided self-help cognitive behaviour therapy for those who hear distressing voices: using factor analysis to test normalisation process theory.

BACKGROUND: The Normalisation Process Theory (NPT) has been used to understand the implementation of physical health care interventions. The current study aims to apply the NPT model to a secondary mental health context, and test the model using exploratory factor analysis. This study will consider the implementation of a brief cognitive behaviour therapy for psychosis (CBTp) intervention. METHODS: Mental health clinicians were asked to complete a NPT-based questionnaire on the implementation of a brief CBTp intervention. All clinicians had experience of either working with the target client group or were able to deliver psychological therapies. In total, 201 clinicians completed the questionnaire. RESULTS: The results of the exploratory factor analysis found partial support for the NPT model, as three of the NPT factors were extracted: (1) coherence, (2) cognitive participation, and (3) reflexive monitoring. We did not find support for the fourth NPT factor (collective action). All scales showed strong internal consistency. Secondary analysis of these factors showed clinicians to generally support the implementation of the brief CBTp intervention. CONCLUSIONS: This study provides strong evidence for the validity of the three NPT factors extracted. Further research is needed to determine whether participants' level of seniority moderates factor extraction, whether this factor structure can be generalised to other healthcare settings, and whether pre-implementation attitudes predict actual implementation outcomes.

Attachment and dissociation as mediators of the link between childhood trauma and psychotic experiences.

Exposure to childhood trauma has been implicated in the development of paranoia and hearing voices, but the mechanisms responsible for these associations remain unclear. Understanding these mechanisms is essential for ensuring that targeted interventions can be developed to better support people experiencing distress associated with paranoia and voices. Recent models have proposed that dissociation may be a mechanism specifically involved in the development of voices and insecure attachment in the development of paranoia. Recent theoretical proposals have added to this and argued that fearful attachment could also lead to increased vulnerability for voices. This study was the first to examine whether dissociation and insecure attachment styles mediated the relationship between childhood trauma and these psychotic experiences. One hundred and twelve participants experiencing clinical levels of psychosis completed measures of dissociation, childhood trauma, attachment, voices, and paranoia. Results revealed positive associations between fearful (but not dismissive and anxious) attachment, dissociation, trauma, and psychotic experiences. Mediation analyses indicated that dissociation, but not fearful attachment, significantly mediated the relationship between trauma and voices. Conversely, both dissociation and fearful attachment significantly mediated the relationship between trauma and paranoia. The findings suggest that insecure attachment might be more strongly related to paranoia than hallucinations and suggest that fearful attachment may be a more promising mechanism to explain this relationship. Furthermore, the findings suggest that the impact of dissociation on psychotic experiences may extend to paranoia. Future research is required to replicate these findings using interview-based attachment measures.
