BACKGROUND
There is a notable a gap between promising research findings and implementation of digital health tools. Understanding and addressing barriers to use is key to widespread implementation.
METHODS
A survey was administered to a self-selecting sample in-person (n = 157) or online (n = 58), with questions examining: i) ownership and usage rates of digital devices among people with psychosis; ii) interest in using technology to engage with mental health services; and iii) facilitators of and barriers to using digital tools in a mental healthcare context.
RESULTS
Device ownership: Virtually all participants owned a mobile phone (95%) or smartphone (90%), with Android phones slightly more prevalent than iPhones. Only a minority owned a fitness tracker (15%) or smartwatch (13%). Device ownership was significantly lower in unemployed people and those without secondary education. Device cost and paranoid ideation were barriers to ownership. Technology and mental health services: Most participants (88%) said they would willingly try a mental health app. Symptom monitoring apps were most popular, then appointment reminders and medication reminders. Half the sample would prefer an app alongside face-to-face support; the other half preferred remote support or no other mental health support. Facilitators: Participants thought using a mental health app could increase their understanding of psychosis generally, and of their own symptoms. They valued the flexibility of digital tools in enabling access to support anywhere, anytime. Barriers: Prominent barriers to using mental health apps were forgetting, lack of motivation, security concerns, and concerns it would replace face-to-face care. Overall participants reported no substantial effects of technology on their mental health, although a quarter said using a phone worsened paranoid ideation. A third used technology more when psychotic symptoms were higher, whereas a third used it less. Around half used technology more when experiencing low mood.
CONCLUSIONS
Our findings suggest rapidly increasing device ownership among people with psychosis, mirroring patterns in the general population. Smartphones appear appropriate for delivering internet-enabled support for psychosis. However, for a sub-group of people with psychosis, the sometimes complex interaction between technology and mental health may act as a barrier to engagement, alongside more prosaic factors such as forgetting.

Review
Persecutory ideas are a major clinical problem and are associated with impaired functioning, reduced compliance with medication and increased risk of hospitalization. Persecutory ideation is defined as the false conviction that others are threatening or conspiring against one. Although persecutory delusions are mainly described and experienced in schizophrenia spectrum disorders, they also occur in other neurological and psychiatric diagnoses including Alzheimer disease, epilepsy, depression, mania, dementia and post-traumatic stress disorder. Moreover, epidemiological data from general and clinical populations indicated that paranoid beliefs occur on a hierarchy of severity and are present to a lesser degree in the general population, with paranoid delusions representing the severe end of a continuum. In this review we focus on the important advances following a decade of research from psychological sciences, and more particularly the work of Daniel Freeman and Philippa Garety in England. Their work has demonstrated that a range of causal factors are involved in the development and maintenance of delusions beyond the traditional cognitive and behavioural models. Indeed, there is now well-validated evidence that sleep disturbances, worry proneness, reasoning biases, such as failure to consider alternative explanations or belief confirmation bias, abnormal experiences such as hallucinations, negative self-beliefs, and safety behaviours, are central factors that contribute to the paranoid phenomenon. In this review, we describe each of these causal factors in detail as well as the clinical interventions developed by Freeman and his collaborators, including the integrative and modular "Feeling Safe" intervention. Broadly speaking, the aim of this psychological intervention is for patients to relearn safety by exposing them to situations they consider as potentially dangerous after reduction of the influence of the maintenance factors described above. A recent publication showed that the Feeling Safe program led to recovery in persecutory delusions for 50% of patients having poor response to antipsychotic medication, making the intervention as the most effective psychological treatment for persecutory delusions. Finally, we will critically discuss the efficacy data from the numerous clinical studies validating its effectiveness. Prospects for the implementation of the Feeling Safe program in France also is discussed.

This study investigated sociodemographic and clinical differences between the sexes in individuals affected by schizophrenia-spectrum disorders (SSD) who accessed outpatient mental health services. Within a retrospective cohort of 45,361 outpatients receiving care in Ferrara (Italy) from 1991 to 2021, those with a SSD diagnosis were compared between the sexes for sociodemographic and clinical characteristics before and after the index date (when the ICD-9: 295.*diagnosis was first recorded) to assess early trajectory, age and type of diagnosis, and severity of illness indicated by medication use, hospitalization, and duration of psychiatric care. Predictors of discharge were also investigated. Among 2439 patients, 1191 were women (48.8%). Compared to men, women were significantly older at first visit (43.7 vs. 36.8 years) and at index date (47.8 vs. 40.6) with peak frequency at age 48 (vs. 30). The most frequent last diagnosis recorded before the index date was delusional disorder (27.7%) or personality disorder (24.3%) in men and depression (24%) and delusional disorder (30.1%) in women. After the index date, long-acting antipsychotics and clozapine were more frequently prescribed to men (46.5% vs. 36.3%; 13.2% vs. 9.4%, p < 0.05) and mood stabilizers and antidepressants to women (24.3% vs. 21.1%; 50.1% vs. 35.5%; p < 0.05). Women had fewer involuntary admissions (10.1% vs. 13.6%) and were more likely to be discharged as the time under care increased (p = 0.009). After adjusting for covariates, sex was not a significant predictor of discharge. Our study confirmed that sex differences exist in clinical and sociodemographic characteristics of outpatients with SSD and that gender considerations might influence the rapidity of diagnosis and medications prescribed. These findings highlight the need to implement a women-tailored approach in specialist care programs for psychoses.

BACKGROUND
In 2009, the Chinese government incorporated severe mental disorders into the central subsidized local health funding project for the effective management, treatment, and reintegration of patients with severe mental disorders from hospitals into the community (Project 686). The conditions that were classified as 'severe' by this project included: schizophrenia, schizoaffective disorders, paranoid disorders, bipolar disorders, mental disorders caused by epilepsy, and mental retardation accompanying mental disorders. Patients in rural communities received better care after project implementation, of which 62.91% were farmers.
OBJECTIVE
This paper attempts to investigate the complex impact of Project 686 on the levels of rehabilitation of patients by their families.
METHODS
The last follow-up visit of the community psychiatrists in city H in 2020 was used as the time point. Finally, 174 samples were used in the analysis model. The type of kinship between family caregivers and patients with mental disorders was operationalized according to the information provided under the 'primary caregiver' item within the basic information section of the follow-up form. The software Stata15 was used to perform descriptive statistics, baseline regression model analysis, and a robustness test on the types of kinship identified and patients' recovery.
RESULTS
The types of kinship, current symptoms, and medication use all affected patients' recovery, were found to have regression coefficients of -0.148, -1.756, and 0.902, respectively. Parents of patients with mental disorders remain in the caregiver category with the largest proportion. Community acceptance of patients is high; current symptoms, medication use, and types of caregiver-patient relationships influence patients' recovery levels.
CONCLUSIONS AND DISCUSSION
Project 686 has solved some of the rehabilitation and living difficulties of patients with mental disorders in rural communities. The types of kinship between family caregivers and patients with mental disorders in rural communities affect patients' rehabilitation levels. Patients' current symptoms and medication use can effectively moderate the impact of kinship type on patients' recovery in terms of complete self-knowledge, productive work, and life and good social relationships. It is necessary for mental illness prevention-treatment organizations to establish supplemental, replacement, and substitution mechanisms for the life and rehabilitation of patients with mental disorders in rural communities. Furthermore, the sense of reward and concern for family caregivers should be actively enhanced, and greater scientific use of the rehabilitation function of the 'family care + village doctor management' model should be made.

BACKGROUND AND HYPOTHESIS
Game theory paradigms, such as the Prisoner's Dilemma Game (PDG), have been used to study nonclinical paranoia, though research using clinical populations has been scarce. We test our novel theoretical model that schizophrenia leads to competitiveness in interpersonal interactions, and that this link is serially mediated by trait paranoia, state paranoia, and distrust.
STUDY DESIGN
In this quasi-experimental study, individuals with schizophrenia spectrum diagnoses with current persecutory delusions (n = 46) and a nonclinical control group (n = 43) played the PDG, and completed measures of trait paranoia, state paranoia, and distrust.
STUDY RESULTS
Individuals with schizophrenia competed more in the PDG than the control group. Supporting our theoretical model, all direct effects were significant: schizophrenia was associated with higher trait paranoia (H1); trait paranoia predicted state paranoia in the PDG (H2); state paranoia in the PDG predicted distrust of the opponent in the PDG (H3); and distrust predicted competition in the PDG (H4). The hypothesized indirect effect of schizophrenia on competition in the PDG via trait paranoia, state paranoia, and distrust was supported in a serial mediation model (H5).
CONCLUSIONS
The findings make clear theoretical and methodological contributions. We provide the first evidence for a theoretical process model by which schizophrenia leads to competitiveness in interpersonal interactions via trait paranoia, state paranoia, and distrust. Game theory paradigms, and the PDG in particular, are important for advancing theory and research on paranoia as it occurs in both clinical and nonclinical populations.

L'Encephale Sep 2023We aimed to assess the impact of the COVID-19 crisis on the occurrence of new hospital admissions for cases of psychosis in France.
OBJECTIVES
We aimed to assess the impact of the COVID-19 crisis on the occurrence of new hospital admissions for cases of psychosis in France.
METHOD
We conducted a retrospective observational study from the French national PMSI database. We included patients hospitalized between 2018 and 2020 with a principal diagnosis of schizophrenia or delusional disorder with no history of psychosis in the previous 10 years. In total, we included 77,172 inpatients at crisis centers and/or in full-time hospitalization at 465 French hospitals. We assessed the number of inpatients during the year of the Covid crisis (2020) and the two years prior (2018, 2019).
RESULTS
The number of inpatients in full-time hospitalization decreased gradually from 2018 to 2020 by 10.6%. This downward trend was observed in all age groups. In contrast, in crisis centers the number of inpatients increased by 13.4% between 2019 and 2020, while a 7.6% decrease was seen between 2018 and 2019. The greatest increase was observed in the 31-60-year age category, and particularly amongst 46-60-year-olds, i.e. 38.0%.
CONCLUSION
The COVID-19 crisis was associated with an increase in the number of inpatients with a new episode of psychosis in crisis centers but not in full-time hospitalization. The profile of patients in crisis centers was different from that seen in preceding years and included more middle-to-late age adults. Particular attention should be given to this category of patients in the crisis environment to prevent the occurrence of new cases of psychosis in France.

Schizotypy is a multidimensional construct that captures a continuum of risk for developing schizophrenia-spectrum psychopathology. Existing 3-factor models of schizotypy, consisting of positive, negative, and disorganized dimensions have yielded mixed evidence of genetic continuity with schizophrenia using polygenic risk scores. Here, we propose an approach that involves splitting positive and negative schizotypy into more specific subdimensions that are phenotypically continuous with distinct positive symptoms and negative symptoms recognized in clinical schizophrenia. We used item response theory to derive high-precision estimates of psychometric schizotypy using 251 self-report items obtained from a non-clinical sample of 727 (424 females) adults. These subdimensions were organized hierarchically using structural equation modeling into 3 empirically independent higher-order dimensions enabling associations with polygenic risk for schizophrenia to be examined at different levels of phenotypic generality and specificity. Results revealed that polygenic risk for schizophrenia was associated with variance specific to delusional experiences (γ = 0.093, P = .001) and reduced social interest and engagement (γ = 0.076, P = .020), and these effects were not mediated via the higher-order general, positive, or negative schizotypy factors. We further fractionated general intellectual functioning into fluid and crystallized intelligence in 446 (246 females) participants that underwent onsite cognitive assessment. Polygenic risk scores explained 3.6% of the variance in crystallized intelligence. Our precision phenotyping approach could be used to enhance the etiologic signal in future genetic association studies and improve the detection and prevention of schizophrenia-spectrum psychopathology.

Estimates of Gaps in Supportive Housing Among Racially and Ethnically Diverse Older Adults with Serious Mental Illness in New York City Boroughs: Manhattan, Bronx, and Brooklyn.
OBJECTIVE
This study aimed to estimate gaps in supportive housing services for racially and ethnically diverse older adults with SMI residing in supportive housing.
METHODS
This study had a total of 753 respondents split into two diagnostic groups, the Delusional and Psychotic Disorders Group, and the Mood (Affective) Disorder Group. Demographic and primary ICD diagnosis data (F2x and F3x) were extracted from medical records. Three elements were measured: supportive housing service needs, fall prevention, and activities in daily living and instrumental activities in daily living. Descriptive statistics (i.e., frequencies and percentages) were used in assessing the demographic characteristics of the sample.
RESULTS
Respondents had reasonable fall prevention measures in place, did not have challenges carrying out activities in daily living or instrumental activities of daily living and did not need homecare services (n = 515, 68.4%). Respondents needed support managing chronic medical conditions (n = 323, ∼43%). Approximately 57% of the total respondents in this study (n = 426) reported the need for hearing, vision, and dental services. Respondents showed high levels of food insecurity (n = 380, 50.5%).
CONCLUSIONS
This is the most extensive study of racially and ethnically diverse older adults with SMI residing in supportive housing. Three areas of unmet need were found: accessing hearing, vision, and dental services, managing chronic health conditions, and food insecurity. These findings can be used to develop new research programs addressing the needs of older adults with SMI and improve late-life circumstances for older adults with SMI.

OBJECTIVE
: Antipsychotic drugs are known as the major cause of non-neoplastic hyperprolactinemia. This study aimed to investigate the levels of serum prolactin depending on the use of antipsychotic drugs in patients through the Clinical Data Warehouse (CDW).
METHODS
: We conducted a cohort search in the CDW application and got 260 patients' medical records diagnosed with schizophrenia, schizotypal and delusional disorders, manic episodes, and bipolar affective disorders who were taking one of risperidone, blonanserin, amisulpride, and olanzapine. After that, we reviewed the medical data and used the ANCOVA analysis and the post hoc test to compare serum prolactin levels among four antipsychotic drug groups.
RESULTS
: Among the 117 subjects included in the analysis, the mean serum prolactin level was 64.6 ± 54.6 ng/ml. Serum prolactin levels were significantly higher in subjects taking risperidone or amisulpride compared to blonanserin and olanzapine. The female subjects who took blonanserin, olanzapine, and risperidone had significantly higher prolactin levels, but there was no difference in serum prolactin levels between sex in the subjects who took amisulpride.
CONCLUSION
: This study suggests the need for regular monitoring of serum prolactin levels in patients who are taking antipsychotics, especially in female patients. And we showed that there is a possibility to conduct more effective and simpler big data research using the CDW. Further studies on the subjects with controlled confounding variables and larger sample groups are needed.

Delusional companion syndrome, an uncommon subtype of delusional misidentification syndrome, has no prior reported cases in patients with primary psychotic disorders. We report a case of delusional companion syndrome in the absence of any organic brain disease, stroke, or severe brain injury, in a young female with schizophrenia. The patient is a 29-year-old G3P3 female, with a history of schizophrenia and major depressive disorder, who, after recently losing custody of her children, presented to the pediatric emergency department for evaluation of her baby doll, which she believed to be her child because the doll wasn't eating or moving well. She became acutely agitated when providers declined to insert an IV line to hydrate the doll and required emergency treatment orders to de-escalate. The patient was admitted to the inpatient psychiatric unit and treated with oral aripiprazole 10 mg, before transitioning to her previous treatment of aripiprazole lauroxil at an increased dose of 882 mg monthly. By the end of admission, the patient grasped that the doll was a toy that had never been alive. This case demonstrates how delusional companion syndrome can occur in young patients with primary psychotic disorders, without a causative neurological insult, and can be treated with antipsychotics. More studies are necessary to further explore the relationship between primary psychotic disorders and delusional companion syndrome.
