Self-assessment scale of auditory verbal hallucinations (SAVH): A novel tool for patients with schizophrenia.

BACKGROUND: A scale for self-assessment of auditory verbal hallucinations (SAVH) was developed for patients, and this study aimed to validate the scale by investigating its psychometric properties. METHODS: Forty one patients with schizophrenia or schizoaffective disorders (DSM-5) self-assessed their hallucinations using nine SAVH questions. Each question was scored from 0 to 5, indicating the severity of the symptoms. Patients were also evaluated with the Brief Psychiatric Rating Scale (BPRS), Auditory Hallucination Rating Scale (AHRS), and Birchwood Insight Scale (BIS). The psychometric properties of the SAVH were assessed by the face, internal consistency, construct, convergent and discriminant validities. RESULTS: SAVH scores were used to examine the psychometric properties. Cronbach's α and Guttman's Lambda-6 were 0.67 and 0.73 respectively. Significant correlations were observed between SAVH and AHRS total scores, as well as BPRS hallucinatory behavior subscores. No significant correlations were found between total SAVH scores and (i) levels of insight or (ii) negative BPRS subscores. Factor analysis on SAVH revealed three factors accounting for 59.3 % of the variance. Most patients found the questions clear, appropriate, and of adequate length. CONCLUSIONS: SAVH demonstrated good psychometric properties, suggesting its utility in assessing auditory verbal hallucinations (AVH). This self-assessment could be valuable in evaluating AVH treatment efficacy, monitoring AVH, and empowering patients.

A digital tool for self-assessment of auditory verbal hallucinations in schizophrenia.

Auditory verbal hallucinations (AVH) are experienced by approximately 70 % of patients with schizophrenia and are frequently associated with high levels of distress. Therefore, alleviating hallucinations is an important therapeutic challenge. However, for prescribing a personalized treatment adapted to the patient, an accurate and detailed assessment of AVH is necessary. Until now, there have been no self-evaluations; instead, only scales based on observer ratings have been used to assess AVH. Nevertheless, self-assessments may enhance patient symptom awareness and increase their insight and involvement in the treatment, promoting empowerment (Eisen et al., 2000). In this context, a mobile app called MIMO was devised in order to monitor AVHs assessed by the patients themselves. This app, including the Self-assessment of Auditory verbal Hallucinations (SAVH-https://sns-dollfus.com/), was devised as an ecological momentary assessment tool. The present study aimed to demonstrate the feasibility and acceptability of this app.

Functional Brain Networks of Minor and Well-Structured Major Hallucinations in Parkinson's Disease.

BACKGROUND: Minor hallucinations (mHs) and well-structured major hallucinations (MHs) are common symptoms of Parkinson's disease (PD) psychosis. OBJECTIVES: To investigate the resting-state networks (RSNs) in patients with PD without hallucinations (PD-nH), with mH (PD-mH), and with MH (PD-MH). METHODS: A total of 73 patients with PD were enrolled (27 PD-nH, 23 PD-mH, and 23 PD-MH). Using seed-based functional connectivity analyses, we investigated the RSNs supposedly related to hallucinations in PD: the default mode network (DMN), executive control network (ECN), dorsal attention network (DAN), ventral attention network (VAN), and visual network (VN). We compared the cognitive function and RSN connectivity among the three groups. In addition, we performed a seed-to-seed analysis to examine the inter-network connectivity within each group using the corresponding RSN seeds. RESULTS: PD-MH group had lower test scores for attention and visuospatial functions compared with those in the other groups. The connectivity of the right intracalcarine cortex within the DAN was lower in the PD-MH group than in the others. The PD-mH and PD-MH groups showed higher connectivity in the left orbitofrontal cortex within DMN compared with the PD-nH group, whereas the connectivity was lower in the right middle frontal gyrus (MFG) within ECN, precuneus cortex within VAN, right middle temporal gyrus and precuneus cortex within DAN, and left MFG within VN. The PD-mH and PD-MH groups showed different inter-network connectivity between the five RSNs, especially regarding DAN connectivity. CONCLUSIONS: DAN dysfunction may be a key factor in the progression from mH to MH in patients with PD. © 2023 International Parkinson and Movement Disorder Society.

Barriers to Treatment of Hallucinations and Delusions in People With Dementia Residing in Long-Term Care.

Importance: Most people with dementia will experience neuropsychiatric symptoms, including psychosis characterized by hallucinations and delusions. Across dementia subtypes, hallucinations and delusions are common, though their prevalence and presentation may vary. These symptoms have been associated with worse outcomes compared with dementia alone, including accelerated functional decline and mortality. Many people with dementia reside in long-term care facilities, and identification and management of hallucinations and delusions in this setting are critical.Observations: For residents in long-term care facilities, the following factors can hinder management of hallucinations and delusions related to dementia: (1) delayed recognition of symptoms; (2) reluctance of staff and family members to acknowledge psychiatric issues; (3) lack of approved pharmacotherapies to treat hallucinations and delusions associated with dementia-related psychosis; and (4) regulatory and institutional guidelines, including the long-term care regulatory guidelines established by the Centers for Medicare and Medicaid Services and the 5-star rating system.Conclusions and Relevance: Barriers to the treatment of hallucinations and delusions in patients with dementia in the long-term care setting are myriad and complex. Early diagnosis of dementia-related psychosis and new treatment options for managing hallucinations and delusions are needed to improve care of this patient population.

A Review of Multimodal Hallucinations: Categorization, Assessment, Theoretical Perspectives, and Clinical Recommendations.

Hallucinations can occur in different sensory modalities, both simultaneously and serially in time. They have typically been studied in clinical populations as phenomena occurring in a single sensory modality. Hallucinatory experiences occurring in multiple sensory systems-multimodal hallucinations (MMHs)-are more prevalent than previously thought and may have greater adverse impact than unimodal ones, but they remain relatively underresearched. Here, we review and discuss: (1) the definition and categorization of both serial and simultaneous MMHs, (2) available assessment tools and how they can be improved, and (3) the explanatory power that current hallucination theories have for MMHs. Overall, we suggest that current models need to be updated or developed to account for MMHs and to inform research into the underlying processes of such hallucinatory phenomena. We make recommendations for future research and for clinical practice, including the need for service user involvement and for better assessment tools that can reliably measure MMHs and distinguish them from other related phenomena.

Development and psychometric evaluation of a Chinese version of auditory hallucination risk assessment scale in patients with a diagnosis of schizophrenia.

AIMS AND OBJECTIVES: To develop a Chinese version of Auditory Hallucination Risk Assessment Scale and evaluate its psychometric properties. BACKGROUND: Auditory hallucination, a common symptom in schizophrenia, has the potential to cause harm to patients and the people around them. However, there has been a paucity of suitable instrument developed in Asian region that can comprehensively and reliably assess its risk and inform interventions. DESIGN: This study involved 2 stages, the development of the Auditory Hallucination Risk Assessment Scale (AHRAS) and testing the psychometric properties of AHRAS. We followed STROBE guidelines in reporting the study. METHODS: Auditory Hallucination Risk Assessment Scale items were developed based on Symptom Management Theory, systematic literature review and findings of a qualitative study on the experience of auditory hallucinations. The items were evaluated by content validity. Auditory Hallucination Risk Assessment Scale was then tested for construct validity, concurrent validity, predictive validity, internal consistency and test-retest reliability in a convenience sample of 156 patients with a diagnosis of schizophrenia. RESULTS: The final version of AHRAS has nine items. Two factors were extracted from AHRAS, which explained 57.74% of the total variance. The score of AHRAS was strongly correlated with that of the Psychotic Symptom Rating Scales-Auditory Hallucinations. The area under the curve was 0.90 for the overall AHRAS score. Sensitivity (86.5%) and specificity (80.0%) were maximal for a mean overall AHRAS score of 13.5, suggesting that this is an appropriate threshold for differentiation. Cronbach's alpha coefficient for internal consistency was 0.82, and intra-class correlation coefficient for test-retest reliability was 0.84. CONCLUSIONS: Auditory Hallucination Risk Assessment Scale has good reliability and validity. It can be used in clinical settings in China and beyond to assess the risk of auditory hallucinations. RELEVANCE TO CLINICAL PRACTICE: Auditory Hallucination Risk Assessment Scale can serve as a tool for nurses and other healthcare professionals to identify patients with high-risk auditory hallucinations, monitor the changes of risk and inform nursing interventions.

Understanding the mental health burden of COVID-19 in the United Kingdom.

This article outlines the mental health burden of COVID-19 in the United Kingdom population, and presents preliminary evidence of less common psychiatric issues, such as paranoia and hallucinations, to which vulnerable groups in the U.K. population may be more vulnerable. It is argued that cognitive-behavioral therapy, with components of mindfulness, should be part of the therapeutic response. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

[Psychopathological consequences of confinement]. / Conséquences psychopathologiques du confinement.

The psychological effects of isolation have already been described in the literature (polar expeditions, submarines, prison). Nevertheless, the scale of confinement implemented during the COVID-19 pandemic is unprecedented. In addition to reviewing the published studies, we need to anticipate the psychological problems that could arise during or at a distance from confinement. We have gone beyond the COVID-19 literature in order to examine the implications of the known consequences of confinement, like boredom, social isolation, stress, or sleep deprivation. Anxiety, post-traumatic stress disorder, depression, suicidal or addictive behaviours, domestic violence are described effects of confinement, but the mechanisms of emergence of these disorders and their interrelationships remain to be studied. For example, what are the mechanisms of emergence of post-traumatic stress disorders in the context of confinement? We also remind the reader of points of vigilance to be kept in mind with regard to eating disorders and hallucinations. Hallucinations are curiously ignored in the literature on confinement, whereas a vast literature links social isolation and hallucinations. Due to the broad psychopathological consequences, we have to look for these various symptoms to manage them. We quickly summarize the diagnostic and therapeutic approaches already in place, such as telemedicine, which is undergoing rapid development during the COVID-19 crisis.

Violence and Suicide Risk Assessment in Youth with Psychotic Disorders: Practical Considerations for Community Clinicians.

Psychosis is a unique and significant risk factor associated with violent and suicidal behavior and warrants special consideration. This article presents a careful review of the literature on violence risk and psychosis and suicide risk and psychosis as it pertains to youth or those who have been newly diagnosed with or are at high risk for psychotic disorders. Each topic is covered in reference to general considerations and specific psychotic symptoms (eg, hallucinations, delusions, paranoia). The reader can refer to practical boxes to assist in identifying relevant risk factors and examples of questions to ask the patient and family.

Functional Behavioral Assessment-based interventions on adults' delusions, hallucinations and disorganized speech: A single case meta-analysis.

The Functional Behavioral Assessment (FBA) approach involves the use of single-case designs (SCD) to study the problem behavior-environment contingencies and conduct interventions that consider this functional relationship. Although this approach has been considered an evidence-based practice (EBP) for the treatment of several psychological problems, no meta-analytic studies of FBA-based interventions on delusions, hallucinations and disorganized speech -commonly operationalized as "atypical vocalizations"- have been carried out. Therefore, the purpose of this study was to review and synthesize the results of FBA-based interventions on adults' atypical vocalizations. We conducted a systematic review and a multi-level meta-analysis of these interventions, using a recently developed effect size estimator for SCD studies (i.e., log response ratio). All the studies that met our eligibility criteria provided evidence supporting the effectiveness of FBA-based interventions on atypical vocalizations, with an overall average effect size of a 72% reduction. Both the publication year and the methodological quality were found to be significant moderators. Despite some methodological limitations, we can conclude that FBA-based interventions are effective to reduce atypical vocalizations. The implications of these results could be of interest for the mental health community.

Assessment of visual misperceptions in patients with Parkinson's disease using single and bistable percepts as testing tools.

BACKGROUND: Visual misperceptions (VMs) and hallucinations (VHs) often go unreported in patients with Parkinson's disease (PD). We assessed the utility of single and bistable visual percepts as testing tools for visual perceptual abnormalities in PD. AIM: To assess VM in patients with PD using single and bistable percepts as testing tools. SETTINGS AND DESIGN: This was a case-control study conducted at a movement disorders clinic. MATERIALS AND METHODS: Thirty patients with PD and 30 age and sex-matched controls were assessed for motor severity and stage using Unified Parkinson's Disease Rating Scale-III (UPDRS-III) and modified Hoehn and Yahr scale. Higher mental functions were assessed by Mini-Mental State Examination (MMSE), Frontal Assessment Battery (FAB), and Trail making tests (TMT-A and B) scores. The participants were presented with monochromatic images representing either "single" or "bistable percepts" and the misperceptions were recorded. VM scores of patients and controls were compared. The correlation between disease duration, treatment period, motor severity, frontal executive functions, and VMs were determined. RESULTS: Twenty-six patients had mild-to-moderate PD. Patients with PD had higher mean VM scores (P < 0.0005). None of the patients reported VHs. TMT-A, TMT-B, TMT-B - A scores were significantly lower in the control group (P < 0.0005). Cases showed significant positive correlation of VM with disease duration, treatment duration, UPDRS-III score, H and Y stage, and TMT A and B and an inverse correlation with MMSE and FAB scores. The patients with VM score greater than the upper limit of normal (Mean + 1.5 standard deviation [SD]), calculated from the control group, showed similar correlation of VM with motor and cognitive parameters. CONCLUSIONS: VMs are frequent in patients with PD when assessed using single and bistable visual percepts. VM correlates with frontal executive dysfunction, disease duration, and severity.

An intervention programme for caregivers of dementia patients with frontal behavioural changes: an explorative study with controlled effect on sense of competence.

AIM: Caregivers of dementia patients experience high levels of burden; this is especially true of caregivers of dementia patients with behavioural problems. As intervention studies for these caregivers are still lacking, we conducted an explorative pilot study into the efficacy of a support programme. METHODS: Participants were caregivers of dementia patients affected by apathy, disinhibition, and/or stereotypical behaviour. All patients had a Frontal Behavioural Inventory score of 11 or higher. Caregivers were randomized to the intervention group or control group (both n = 15). The intervention was a 6-month programme that consisted of psychoeducation, social support, and behavioural cognitive therapy. Quantitative and qualitative data were collected at baseline and after the intervention. RESULTS: An increased sense of competence was found in the intervention group. Burden, perceived stress, and depressive symptoms decreased, although the difference between the intervention and control groups was not significant. CONCLUSIONS: Caregivers' sense of competence improved as a result of the support programme, and caregivers revealed its comprehensive supportive effects. Further research into the efficacy of the programme on a larger scale is recommended.

Sociodemographic and clinical correlates of psychotic symptoms in the general population: Findings from the MHGP survey.

BACKGROUND: We aimed to explore the sociodemographic and psychiatric correlates of psychotic symptoms in a large general population sample. METHODS: The French Mental Health in the General Population cross-sectional survey interviewed 38,694 individuals using the Mini International Neuropsychiatric Interview. We looked for associations between the presence of lifetime psychotic symptoms, sociodemographic characteristics (including migrant status over three generations) and clinical characteristics. We then looked for associations regarding only hallucinations, delusional symptoms, and the co-occurrence of both hallucinations and delusional symptoms. To test the psychosis continuum hypothesis, associations with sociodemographic characteristics were compared with the characterized psychotic disorders' associations. RESULTS: We found that 22.3% of the population declared psychotic symptoms without psychotic disorders, including 5.7% who declared hallucinations, 20.5% delusional symptoms, 4.0% both hallucinations and delusional symptoms, and 2.8% characterized psychotic disorders. The presence of psychotic symptoms was associated with young age, migrant status (over three generations), secondary education level, low-income level and never-married and separated marital status. Hallucinations, delusional symptoms and the co-occurrence of both hallucinations and delusional symptoms showed the same correlates, and hallucinations were also associated with elementary education level. Characterized psychotic disorders showed the same correlates. Concerning clinical outcomes, the presence of psychotic symptoms, hallucinations and delusional symptoms was associated with all non-psychotic disorders, i.e., bipolar, depressive, alcohol use, generalized anxiety, social phobia, panic and post-traumatic stress disorders and dysthymia (except dysthymia, which was not associated with hallucinations). CONCLUSIONS: Our results indicate that psychotic symptoms are associated with broad psychopathologies and support the continuum model of psychosis.

Characteristics, correlates, and assessment of psychosis in Parkinson disease without dementia.

INTRODUCTION: Considering that psychosis in Parkinson disease (PD) is associated with worse outcomes, including dementia, we aimed to study the characteristics, correlates, and assessment of PD psychosis in those without dementia. METHODS: 101 PD subjects without dementia (Montreal Cognitive Assessment ≥21/30) were recruited to participate in a study of neuropsychiatric symptoms in PD. This study included a baseline standard neurological exam and common PD symptom assessments. Using the Scale for the Assessment of Positive Symptoms (SAPS) and separate assessment of visual illusions and sense of presence, NINDS-NIMH criteria for PD psychosis were applied. RESULTS: Of the 33 (32.7%) PD subjects who met diagnostic criteria for psychosis in PD, visual illusions were most common (72.7%), followed by visual hallucinations (39.4%). Adjusted for presence of REM sleep behavior disorder (RBD) (p = 0.097), use of dopamine agonists (OR = 3.7, p = 0.012) and greater autonomic symptom burden (OR = 1.1 (per 1-unit change in score on SCOPA-AUT), p = 0.012) were associated with greater risk of psychosis. Use of dopamine agonists (OR = 5.0, p = 0.007), higher MDS-UPDRS Part II score (OR = 1.1, p = 0.010), and presence of RBD (OR = 4.8, p = 0.012) were independent predictors of visual hallucinations and visual illusions. MDS-UPDRS item 1.2 score ≥1 had highly correlated with the SAPS score (r = 0.65, p < 0.0001), but was 42% sensitive and 96% specific for identifying psychosis. CONCLUSION: This study confirms the association between dopamine agonists and psychosis in PD patients without dementia. The association of RBD, autonomic symptoms, and MDS-UPDRS Part II scores with psychosis underscore its link to brainstem dysfunction and greater PD motor symptom severity.

Distress Associated with Dementia-Related Psychosis and Agitation in Relation to Healthcare Utilization and Costs.

OBJECTIVES: Explore the relationship between behavioral and psychological symptoms of dementia (BPSD; specifically, delusions, hallucinations, and agitation/aggression) and associated caregiver distress with emergency department (ED) utilization, inpatient hospitalization, and expenditures for direct medical care. DESIGN/SETTING/PARTICIPANTS: Retrospective cross-sectional cohort of participants with dementia (N = 332) and informants from the Aging, Demographics, and Memory Study, a nationally representative survey of U.S. adults >70 years old. MEASUREMENTS: BPSD of interest and associated informant distress (trichotomized as none/low/high) were assessed using the Neuropsychiatric Inventory (NPI). Outcomes were determined from one year of Medicare claims and examined according to presence of BPSD and associated informant distress, adjusting for participant demographics, dementia severity, and comorbidity. RESULTS: Fifty-eight (15%) participants with dementia had clinically significant delusions, hallucinations, or agitation/aggression. ED visits, inpatient admissions, and costs were not significantly higher among the group with significant BPSD. In fully adjusted models, a high level of informant distress was associated with all outcomes: ED visit incident rate ratio (IRR) 3.03 (95% CI: 1.98-4.63; p < 0.001), hospitalization IRR 2.78 (95% CI: 1.73-4.46; p < 0.001), and relative cost ratio 2.00 (95% CI: 1.12-3.59; p = 0.02). CONCLUSIONS: A high level of informant distress related to participant BPSD, rather than the symptoms themselves, was associated with increased healthcare utilization and costs. Effectively identifying, educating, and supporting distressed caregivers may help reduce excess healthcare utilization for the growing number of older adults with dementia.

Neuropsychiatric symptoms in dementia may predict caregiver burden: a Sicilian exploratory study.

BACKGROUND: Behavioural and psychological symptoms of dementia are very common. They represent a main cause of burden and distress in caregivers and can lead to early institutionalization of patients. We aimed to find the most specific behavioural and psychological symptoms of dementia that can strongly affect the caregivers' burden. METHODS: Twenty-seven patients and their caregivers were enrolled in this study. All of the patients were affected by Alzheimer's, vascular, or frontotemporal dementia and were evaluated with the Neuropsychiatric Inventory and Mini-Mental State Examination. Caregivers were administered the Caregiver Burden Inventory. RESULTS: Apathy, depression, anxiety, and agitation were the most common symptoms and were found in up to 90% of the patients. We detected strong correlations between patient neuropsychiatric symptoms, (i.e. irritability, hallucinations, aberrant motor behavioural, depression, and agitation) and Caregiver Burden Inventory scores. Multiple regression analysis found hallucinations, irritability, and depression to be significant predictors of caregiver burden. Moreover, the Neuropsychiatric Inventory score was more closely related to caregiver burden than the Mini-Mental State Examination score. CONCLUSION: Our results revealed that demented patients' behavioural problems are related to the level of caregiver burden and distress. Further investigations are needed to differentiate the present findings among dementia subtypes and to better evaluate the effect of caregivers' personal characteristics on their own burden.

Multidisciplinary assessment of patients with musical hallucinations, tinnitus and hearing loss.

BACKGROUND: Although auditory hallucinations are considered a psychopathological phenomenon, musical hallucinations have been reported in individuals without psychosis but with auditory symptoms (tinnitus and/or hearing loss). Thus, a possible different cognitive functioning may be involved in musical hallucinations. The aim of the study was to characterize patients with tinnitus and musical hallucinations through a multidisciplinary assessment, allowing a better understanding of these concomitant phenomena. SAMPLING AND METHODS: As this sample is rare to find, all consecutive patients with tinnitus, hearing loss and musical hallucinations were included over a 3-year period, excluding those unable to respond. All subjects underwent the following assessments: (1) otolaryngological and audiological assessment (physical examination and audiometry), (2) neurological assessment (cognition, electroencephalogram and imaging examination) and (3) psychiatric assessment (structured interview). RESULTS: A total of 16 patients were included (87.5% women; mean age 61.43 ± 15.99 years). The otolaryngological examination was normal in all cases, but audiometry revealed that the degree of hearing loss was severe to profound in 68.75% of participants. Neurological assessment showed electroencephalogram changes in only 17.6% of cases, while 25% presented with mild attention deficit and 43.75% had small foci of gliosis or ischemia on the imaging examination. Psychiatric assessment showed that 68.75% of cases had depression, 6.25% had anxiety disorder and 25% had no psychiatric conditions. CONCLUSIONS: Musical hallucinations were strongly associated with female elderly adults and with mood disorders. Thus, in contrast to common auditory hallucinations, patients with musical hallucinations associated with tinnitus and hearing loss should be offered a more multidisciplinary assessment.

The impact of social deprivation on paranoia, hallucinations, mania and depression: the role of discrimination social support, stress and trust.

The negative implications of living in a socially unequal society are now well documented. However, there is poor understanding of the pathways from specific environmental risk to symptoms. Here we examine the associations between social deprivation, depression, and psychotic symptoms using the 2007 Adult Psychiatric Morbidity Survey, a cross-sectional dataset including 7,353 individuals. In addition we looked at the mediating role of stress, discrimination, trust and lack of social support. We found that the participants' neighbourhood index of multiple deprivation (IMD) significantly predicted psychosis and depression. On inspection of specific psychotic symptoms, IMD predicted paranoia, but not hallucinations or hypomania. Stress and trust partially mediated the relationship between IMD and paranoid ideation. Stress, trust and a lack of social support fully mediated the relationship between IMD and depression. Future research should focus on the role deprivation and social inequalities plays in specific manifestations of psychopathology and investigate mechanisms to explain those associations that occur. Targeting the mediating mechanisms through appropriate psychological intervention may go some way to dampen the negative consequences of living in an unjust society; ameliorating economic injustice may improve population mental health.

Logic and justification for dimensional assessment of symptoms and related clinical phenomena in psychosis: relevance to DSM-5.

Work on the causes and treatment of schizophrenia and other psychotic disorders has long recognized the heterogeneity of the symptoms that can be displayed by individuals with these illnesses. Further, researchers have increasingly emphasized the ways in which the severity of different symptoms of this illness can vary across individuals, and have provided evidence that the severity of such symptoms can predict other important aspects of the illness, such as the degree of cognitive and/or neurobiological deficits. Additionally, research has increasingly emphasized that the boundaries between nosological entities may not be categorical and that the comorbidity of disorders may reflect impairments in common dimensions of genetic variation, human behavior and neurobiological function. As such, it is critical to focus on a dimensional approach to the assessment of symptoms and clinically relevant phenomena in psychosis, so as to increase attention to and understanding of the causes and consequences of such variation. In the current article, we review the logic and justification for including dimensional assessment of clinical symptoms in the evaluation of psychosis in the Fifth Edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5).
