Strachan L, McEvoy P, Arntz A, Steel C, Paulik G. Effectiveness of Imagery Rescripting for Trauma-Affected Voice Hearers: An Open Trial. Clin Psychol Psychother 2024; 31:e3052. [PMID: 39295204 DOI: 10.1002/cpp.3052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2024] [Revised: 08/14/2024] [Accepted: 08/17/2024] [Indexed: 09/21/2024]
Abstract
OBJECTIVE People who hear voices (auditory verbal hallucinations) often have post-traumatic stress disorder (PTSD) symptoms. Cognitive behavioural therapies (CBT) have yielded inconsistent findings when treating voices and PTSD symptoms in voice hearers. Preliminary evidence suggests imagery rescripting (ImRs) is associated with large reductions in voice hearing and PTSD symptoms. This study replicated past studies using a larger sample to examine the effectiveness of ImRs in reducing such symptoms. METHOD Participants (N = 49; 65.3% female; Mage = 35.86) were clients at an Australian transdiagnostic clinic for voice hearers. A one-arm open trial design was used with three pre-treatment baselines and a mid-treatment, post-treatment and 3-month follow up assessments of PTSD symptoms (Posttraumatic Diagnostic Scale for DSM-5), voices (Hamilton Program for Schizophrenia Voices Questionnaire) and emotional symptoms (Depression Anxiety and Stress Scales-21). Five single-item measures were administered weekly to explore the trajectories of change in trauma intrusions, voice-related distress, voice frequency and positive and negative voice valance. RESULTS ImRs was associated with very large reductions in PTSD symptoms and voices (both emotional and physical characteristics of voices) and emotional symptoms at post-treatment and follow-up (η2 p = 0.24-0.44). There were medium-large to large reductions in weekly symptoms of intrusions, voice-related distress, voice frequency and negative voices (η2 p = 0.12-0.16) and a non-significant increase in positive voices (η2 p = 0.05). CONCLUSIONS This study provides further evidence that ImRs is an effective treatment for voices and PTSD symptoms in voice hearers with a range of diagnoses. Randomised controlled trials are needed to compare the efficacy of ImRs to CBT protocols.

Abstract
BACKGROUND A range of traumas have been linked to voices (auditory verbal hallucinations) and unusual perceptual experiences (UPEs) in other perceptual-sensory domains. Models of PTSD and positive symptoms of psychosis are insufficient in explaining the relationship between trauma and voices. The trauma-related voices (TRV) model was developed to generate novel research in this area. AIMS This study aimed to investigate pathways from trauma to the frequency of UPEs based on a subset of hypothesised relationships in the TRV model. MATERIALS The PTSD Diagnostic Scale for DSM-5, State Adult Attachment Measure, Depression Anxiety and Stress Scales-21, Perth Emotion and Regulation Competency Inventory, Dissociative Experiences Measure Oxford, and Multi-modality Unusual Perceptual Experiences Questionnaire. METHODS We used path analysis in a non-clinical sample (N = 528) to model indirect effects from diverse trauma experiences to the frequency of multi-sensory UPEs via a subset of mediators within the TRV model: insecure attachment, emotion regulation deficits, negative affect and dissociation. RESULTS Our model was an excellent fit to the data and accounted for 37.1% of variance in UPE frequency, and all direct (βs = .14-.61) and indirect pathways (βs = .01-.08) were significant (ps < .001). DISCUSSION Our findings suggest that insecure attachment may link diverse trauma experiences to emotion regulation deficits and negative affect, which are linked to UPE frequency via dissociation. CONCLUSION Our findings provide preliminary evidence for a subset of relationships within the TRV model. Future studies are needed to gather stronger evidence of temporality and causation between these factors, and to test broader pathways within the TRV model.

Strachan LP, Paulik G, Roberts L, McEvoy PM. Voice hearers' explanations of trauma-related voices and processes of change throughout imagery rescripting: A qualitative exploration. Psychol Psychother 2023; 96:982-998. [PMID: 37638740 DOI: 10.1111/papt.12491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 08/01/2023] [Accepted: 08/08/2023] [Indexed: 08/29/2023]
Abstract
OBJECTIVES Post-traumatic stress is common among people who hear voices (auditory verbal hallucinations), many of whom hear trauma-related voices, whereby voice content is related to past trauma. Preliminary evidence suggests that imagery rescripting (ImRs) may more effectively reduce post-traumatic stress and voices compared to treatments that are based on existing models of PTSD or positive symptoms. No known studies have explored the potential maintaining factors of trauma-related voices in relation to ImRs. We aimed to uncover insights into the factors that maintain trauma-related voices and how ImRs may influence such factors by exploring voice hearers' explanations of voices and experiences of change throughout ImRs. DESIGN Thematic analytical methodology was used due to the study's critical epistemological framework. METHODS Semi-structured interviews explored relationships between trauma and voices, and experiences of change and stability throughout ImRs in a transdiagnostic sample (N = 10) who underwent 10-18 weekly ImRs sessions. Thematic analysis was used to develop themes. RESULTS Two themes captured explanations of voices, which suggested voices may have counterproductive protective functions. Three themes captured psychological experiences during ImRs, which reflected concepts such as freedom to experience emotions, and experiences of justice, closure and grieving. Three themes described the outcomes of ImRs, reflecting concepts such as increased confidence, coping, perceived safety and voices becoming less powerful. CONCLUSIONS Trauma-related voices may have underlying protective functions and ImRs may support emotional expression, adaptive trauma re-appraisals and improve self-worth and coping self-efficacy. These change processes may have clinical implications in ImRs and other treatments for trauma-affected voice hearers.

Abstract
OBJECTIVES Little is known about the factors that can maintain the distress related to voice-hearing experiences in youth. Building upon understandings developed with adults, this study aimed to explore the associations between negative relating between hearer and voices, persecutory beliefs about voices and voice-related distress in a clinical sample of adolescents. The study also aimed to investigate associations between relating to voices and wider patterns of social relating. DESIGN This was an observational, cross-sectional, survey study. METHODS Thirty-four young people (age 14-18 years) who were hearing voices completed measures about voices (characteristics, relating and beliefs) and relating to social others (negative relating styles, social connectedness and belongingness). Participants were patients of NHS mental health services. Bivariate correlations explored associations between relating to voices and distress, beliefs about voices and distress, and between relating to voices and social relating variables. RESULTS Perceiving the voices as dominant, intrusive, and persecutory and resisting them was significantly associated with distress. Adjusting for loudness and negative content rendered the association between persecutory beliefs and distress non-significant. Fear of separation and of being alone in relation to social others was associated with distancing from voices. Being suspicious, uncommunicative and self-reliant and/or being sadistic and intimidating towards social others was significantly associated with dependence towards the voices. Greater hearer-to-voice dependence was associated with lower perceived social belongingness and connectedness. CONCLUSIONS Beliefs about voices being persecutory, dominant, intrusive and resisting voices seem to be significant contributors of distress in young people. In terms of proximity and power, relating to voices and social others appears to be contrasting.

Abstract
OBJECTIVE People who experience distressing voices frequently report negative (e.g. abusive or threatening) voice content and this is a key driver of distress. There has also been recognition that positive (e.g. reassuring, or guiding) voice content contributes to better outcomes. Despite this, voice content has been neglected as a standalone outcome in evaluations of psychological therapies for distressing voices. We aimed to examine whether a modular cognitive-behavioural therapy (CBT) intervention for voices led to changes in negative and positive voice content. DESIGN/METHODS In a naturalistic, uncontrolled pre- and post- service evaluation study, 32 clients at an outpatient psychology service for distressing voices received eight sessions of CBT for distressing voices and completed self-report measures of negative and positive voice content at pre-, mid- and post- therapy. RESULTS There was no significant change in positive voice content. There was no significant change in negative voice content from pre- to post-therapy; however, there was a significant change in negative voice content between mid and post-treatment in which the cognitive therapy component was delivered. The CBT treatment was also associated with significant changes in routinely reported outcomes of voice-related distress and voice severity. CONCLUSIONS The cognitive component of CBT for distressing voices may be associated with changes in negative, but not positive, voice content. There may be benefit to enhancing these effects by developing treatments targeting specific processes involved in negative and positive voice content and further exploring efficacy in well-powered, controlled trials with more comprehensive measures of voice content.

Abstract
BACKGROUND Most voice hearers report childhood trauma. Many voice hearers report comorbid post-traumatic stress symptoms and that the content of their voices (auditory verbal hallucinations) is directly (voices repeat phrases spoken by perpetrators) or indirectly (voice content and trauma is thematically similar) related to their trauma. The factors that maintain trauma-related voices are unknown, and there is limited research in this area. This study aimed to identify potential maintaining factors of trauma-related voices by reviewing models of post-traumatic stress disorder (PTSD) and positive symptoms of psychosis. METHOD Models of PTSD and positive symptoms were reviewed to identify potential factors that are unique and common to both sets of symptoms. RESULTS We reviewed 10 models of PTSD, 4 models of positive symptoms, and 2 trauma-informed models of voice hearing. One model provided a theoretical explanation of different types of trauma-related voices. Twenty-one factors were extracted from 16 theoretical models. No existing model incorporated all these factors. DISCUSSION Existing PTSD and positive symptom models present a range of common and unique factors. There may be value in extending existing integrative models to include a broader range of potential factors that could explain different pathways to, and expressions of, trauma-related voices. A future research agenda is presented to investigate how such an extension could lead to more complete individualized case formulations and targeted treatments.

Abstract
Older adults experience hallucinations in a variety of social, physical, and mental health contexts. Not everyone is open about these experiences, as hallucinations are surrounded with stigma. Hence, hallucinatory experiences in older individuals are often under-recognized. They are also commonly misunderstood by service providers, suggesting that there is significant scope for improvement in the training and practice of professionals working with this age group. The aim of the present article is to increase knowledge about hallucinations in older adults and provide a practical resource for the health and aged-care workforce. Specifically, we provide a concise narrative review and critique of (1) workforce competency and training issues, (2) assessment tools, and (3) current treatments and management guidelines. We conclude with a brief summary including suggestions for service and training providers and future research.

Abstract
Voice power is an important concept in daily life of voice hearers and in the support and therapy for voice hearers who seek help. Therefore, the ability to examine voice power differentials between a voice and a voice hearer is essential. The present study aimed to collect data on voice power differentials and to further validate the Voice Power Differential Scale (VPD). 105 participants aged ≥ 18 with an ICD10 F2-diagnosis that included hearing voices were included in this study. Internal consistency was good (alpha = 0.792), as well as test-retest-reliability (r = 0.855) and correlations with other constructs were generally as expected. The VPD questionnaire results correlated negatively with the Beliefs About Voices Questionnaire-Revised’s (BAVQ-R) items of Benevolence and Engagement-emotion. It correlated positively with Omnipotence and Resistance-emotion, as well as with Negative Content on the Psychotic Symptoms Rating-Scale (PSYRATS). Unexpectedly, no correlations were found with overall severity and command hallucinations. The Voice Power Differential Scale is an important tool for assessing and formulating a voice hearer’s experience when they seek treatment or support for their verbal auditory hallucinations. The results of this study enrich the on-going discussion about the importance of voice power for voice hearers.

Abstract
Abstract
Access to cognitive behaviour therapy for those with psychosis (CBTp) remains poor. The most frequently endorsed barrier to implementation is a lack of resources. To improve access to CBTp, we developed a brief form of CBTp that specifically targets voice-related distress. The results of our pilot trial of guided self-help CBT for voices (GiVE) suggest that the therapy is both acceptable and beneficial. The present study aims to explore the subjective patient experience of accessing GiVE in the context of a trial. We interviewed nine trial participants using the Change Interview and a mixed methods approach. Most participants reported at least one positive change that they attributed to GiVE. We extracted five themes: (1) changes that I have noticed; (2) I am not alone; (3) positive therapy experiences; (4) I want more therapy; and (5) helping myself. The themes indicate that participating in the GiVE trial was generally a positive experience. The main areas in which participants experienced changes were improved self-esteem, and the ability to cope with voices. Positive changes were facilitated by embracing and enacting ‘self-help’ and having support both in and out of the therapy sessions. The findings support the use of self-help materials with those distressed by hearing voices, but that support both within and outside the clinical setting can aid engagement and outcomes. Overall, the findings support the continued investigation of GiVE.
Key learning aims
(1)
To explore participants’ experience of accessing GiVE as part of a trial.
(2)
To identify what (if any) changes participants noticed over the course of the GiVE trial.
(3)
To identify what participants attribute these changes to.
