Relationship of sociodemographic and clinical characteristics to mechanical restraint used in a psychiatric hospital in Spain.

BACKGROUND: Coercive measures have been applied in mental health fields throughout history, denying people with mental illness the ability to decide, even though there is increasing evidence that these measures bring few benefits to these individuals. OBJECTIVE: The objective of this study was to analyse the sociodemographic and clinical characteristics most likely associated with the use of mechanical restraints (MRs) in psychiatric hospital settings. DESIGN, SETTINGS AND PARTICIPANTS: This was a descriptive, comparative and analytical cross-sectional study in people with mental disorders who were hospitalized in two hospitals in the Autonomous Valencian Community (Spain). We included a total of 91 participants who completed the Scale to Assess Unawareness of Mental Disorder (SUMD), Positive and Negative Syndrome Scale (PANSS), Barrat's Impulsiveness Scale and the Hamilton Anxiety Scale. RESULTS: The results we collected indicated that the patients most likely to be mechanically restrained were younger people with less awareness of their symptoms and disease, previous admissions to a psychiatric hospital and cohabitation with parents and/or family. In addition, having been admitted involuntarily, previously having had MRs applied, presenting more positive psychotic symptoms and habitual caffeine consumption all predicted the use of MRs. CONCLUSIONS: The variables that were able to predict MR were involuntary admission, previous use of MR, the presence of positive psychotic symptoms and caffeine consumption. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Evaluation of the sociodemographic and clinical characteristics of patients can help health professionals, especially nurses, to recognize patients who are at risk of requiring MR. This allows mental health practitioners to take these factors into account during interventions or when implementing programmes designed to reduce the use of coercive measures in psychiatric hospital settings. IMPACT: What problem did the study address? Coercive measures have been applied in mental health fields throughout history, with no benefits to these patients. What were the main findings? There are studies that relate some variables to MR in psychiatric settings, but we have been able to find variables capable of predicting MR such as involuntary admission, previous use of MR, the presence of positive psychotic symptoms and caffeine consumption. Where and on whom will the research have an impact? The findings of this study allow for the reduction of MRs in psychiatric units. The sociodemographic and clinical characteristics found to be related to MR will help professionals identify when a patient is admitted in order to use specific interventions aimed at preventing the use of MRs during admission. This is the first study to indicate a relationship between caffeine consumption and the use of MRs. Further studies will be necessary to verify if controlled caffeine supplementation during admission to psychiatric units could become an additional strategy contributing to preventing the application of MR specifically in individuals who habitually consume coffee or caffeine-containing beverages daily. REPORTING METHOD: We have adhered to relevant EQUATOR guidelines using the STROBE reporting method. PATIENT CONTRIBUTION: No patient or public contribution.

Exploring the association between lifetime traumatic experiences and positive psychotic symptoms in a group of long-stay patients with schizophrenia: the mediating effect of depression, anxiety, and distress.

BACKGROUND: Positive psychotic symptoms of schizophrenia are generally characterized by hallucinations and delusions. We propose to assess the relationship between total composite trauma and positive psychotic symptoms, along with the mediation effect of cognition, fear of COVID-19, insomnia, anxiety, distress, and depression of Lebanese patients with schizophrenia. METHODS: A cross-sectional study was carried out, between June and July 2021, by deriving data from 155 long-stay in-patients diagnosed with schizophrenia. RESULTS: Depression, anxiety, and distress but not cognitive impairment, insomnia, and fear of COVID-19) mediated the association between lifetime traumatic experiences and positive psychotic symptoms. Higher traumatic experiences were associated with greater depression, anxiety, and distress, indicating a significant positive total effect on positive psychotic scores. Moreover, higher depression, anxiety, and distress were significantly associated with higher positive psychotic symptoms. CONCLUSION: Our results contribute to the existing knowledge by suggesting other possible intervention paths through mediating factors. Interventions that improve anxiety, depression, and distress severity may be effective in reducing positive psychotic symptoms among patients with schizophrenia having experienced lifetime trauma.

Functionality appreciation is inversely associated with positive psychotic symptoms in overweight/obese patients with schizophrenia.

BACKGROUND: While the relationship between negative aspects of body image and positive schizophrenia symptoms was extensively investigated and is relatively well-established, there is a dearth of literature on the relationship between positive symptoms and positive aspects of body image, such as body appreciation and functionality appreciation, in patients with schizophrenia. This study aimed to (1) compare weight stigma, body and functionality appreciation between obese/overweight and normal-weight patients with schizophrenia, and (2) explore the associations between these variables and positive psychotic symptoms in the obese/overweight group. METHOD: A cross-sectional study was conducted in the Psychiatric Hospital of the Cross, Lebanon during September 2022 recruiting selected in-patients diagnosed with schizophrenia. Patients were classified as overweight/obese if they had a BMI > 25 (N = 76 (37.25%), aged 55.57 ± 11.30 years, 42.6% females). The Weight self­stigma questionnaire, the Functionality Appreciation Scale, and the Body Appreciation Scale, and the Positive and Negative Syndrome Scale (PANSS) were used. RESULTS: No significant difference was found between overweight/obese and normal-weight patients for all variables, except for weight stigma; a significantly higher weight stigma score was significantly found in overweight/obese compared to normal-weight patient. In the bivariate analysis, higher functionality appreciation was significantly associated with higher positive PANSS scores. The results of the linear regression, taking the positive PANSS score as the dependent variable, showed that higher functionality appreciation (Beta = - 0.52) and higher social support (Beta = - 0.16) were significantly associated with lower positive PANSS scores, whereas having a secondary education level compared to illiteracy (Beta = 7.00) was significantly associated with higher positive PANSS scores. CONCLUSION: Although based on cross-sectional data, these findings preliminarily suggest that higher functionality appreciation can help reduce the severity of positive psychotic symptoms in overweight/obese schizophrenia patients, and that interventions aimed at improving functionality appreciation could be regarded beneficial therapeutic targets in the treatment of psychosis.

Prevalence, service use and clinical correlates of hallucinations and delusions in an out-patient population from India.

BACKGROUND: Despite the persistent public health problem of positive psychotic symptoms, understanding of symptom specific prevalence rates, clinical correlates and service utilisation are sparse. AIMS: The current study aimed to establish prevalence, clinical and service utilisation correlates of hallucinations and delusions in people accessing outpatient clinics in Tamil Nadu, India. METHODS: Secondary patient data from outpatient clinics, over a 12-month period, in 2016, was used for analysis (N = 917). Based on the presence of positive psychotic symptoms (PPSx), the sample was divided into four groups for analysis- hallucinations-only (H), delusions-only (D), both hallucinations and delusions (HD) and neither PPSx (N-PPSx). RESULTS: Findings indicate that the most prevalent PPSx were hallucinations (10.7%) however, barriers to service utilisation and clinical correlates were associated predominantly with the D and the HD group; as was severe work impairment. Yet, this group was most likely to remain with psychiatric services. Lastly, diagnostic challenges were apparent within the sample. CONCLUSIONS: The study revealed that despite more barriers to service utilisation, persons with PPSx remain in contact with services. Yet prognosis remains only moderate at best, indicating other mediating and underlying factors impeding recovery may be interplaying and, therefore, a need for enhanced biopsychosocial approaches.

Is change over time in psychotic symptoms related to social functioning?

OBJECTIVE: In psychosis, treatment often focuses on symptom reduction whereas social functioning is also essential. In this study, we investigate positive psychotic symptoms and medication use in relation to social functioning over a 3-year time-period in 531 patients diagnosed with psychosis. Furthermore, relations of positive symptoms with needs for care and quality of life were also investigated. METHOD: Using repeated measures analysis, changes were measured over time. Hereafter, mixed model analyses were performed to determine the associations of social functioning, needs for care, and quality of life with psychotic symptoms and patient characteristics. Finally, we assessed differences in symptoms and medication dose between those with an increase and those with a decrease in social functioning. RESULTS: Patients significantly improved in social functioning, while psychotic symptoms increased. Improvement in social functioning was associated with younger age, higher IQ, and lower social functioning at T1, but not with positive symptoms. Also, improvement in social functioning was found to be related to a decrease in the dose of clozapine. Improvement in social functioning occurs despite worsening of positive symptoms. CONCLUSIONS: The findings suggest the need to further explore the relation between symptomatology, social functioning, and medication use. In the treatment of psychotic disorders, one should reconsider the strong focus on reducing psychotic symptoms. The current focus needs to shift much more toward improving functional outcome, especially when the patient expresses a desire for change in this respect.

Benefits of Social Contact in Individuals With Psychotic Symptoms: Do Closeness of the Contact and Empathic Skills Make the Difference?

Objectives: Social contact is known to be beneficial for humans' mental health. Individuals with psychotic symptoms (PS) tend to show poorer social and interpersonal functioning. However, in this patient population, social contact may be crucial for their mental wellbeing and treatment success. Additionally, closeness of social contact (familiar versus less familiar others), rather than only the presence or absence of social contacts, may play an important role. Empathy may heighten the beneficial effects of social/close contact on mental health, facilitating interactions. We investigated the association between social contact and closeness of contact on mental health, defined as positive symptoms, positive affect and negative affect in PS and control participants, with empathy as a moderator. Methods: Participants were 16-30 years old. Information regarding social/close contact and mental health was obtained using the experience sampling method in individuals with PS (n = 29) and healthy controls (n = 28). Empathy was measured using a self-report questionnaire. Results: Social contact was associated with higher positive affect in the total sample. Contact with close as opposed to less close others was related to better mental health: It was associated with lower positive symptoms in the PS group, and with more positive affect in the total sample. Empathy moderated the association between closeness of contact and positive affect in the total sample, in which the combination of higher levels of empathy combined with the presence of close contact was associated with higher positive affect in the total sample. However, the direct association between empathy and positive affect was not significant per group of contact. Conclusion: The results suggest that social contact, but especially contact with a close other is important for mental health outcomes: Contact with close others is beneficial for positive affect in the total sample and for positive symptoms in individuals with PS.

Temporal dynamics of suspiciousness and hallucinations in clinical high risk and first episode psychosis.

The objective of the current study is to elucidate the temporal dynamics of suspiciousness and hallucinations as they occur in daily life in the early stages of psychosis. Their prevalence and co-occurrence, as well as their temporal relation to affect and delusions, were compared between patients with a first psychotic episode (FEP) and individuals at clinical high risk for psychosis (CHRp). The Experience Sampling Method was used to investigate suspiciousness and hallucinatory experiences, delusions, and affect at semi-random moments throughout six days in 33 CHRp and 34 FEP. Overall, 91% of CHRp and 59% of FEP reported suspiciousness, and 24% and 39% reported hallucinations, respectively. Hallucinations almost always co-occurred with suspiciousness, whereas suspiciousness was often present without hallucinations. Suspicious episodes in CHRp occurred with marked increases in delusional intensity, while hallucinatory experiences were mostly absent. In FEP, a decrease of positive affect preceded suspicious episodes, while an increase of negative affect preceded hallucinatory episodes. Our results indicated the presence of a delusional mood (atmosphere) in CHRp as an experience in itself, without co-occurring or following hallucinations, thus refuting the anomalous experience hypothesis of psychosis. The co-occurrence of hallucinations, on the other hand, indicates a more severe stage of symptomatology.

Genetic Variability of TCF4 in Schizophrenia of Southern Chinese Han Population: A Case-Control Study.

Objective: Schizophrenia is thought to be a neurodevelopmental disorder. As a key regulator in the development of the central nervous system, transcription factor 4 (TCF4) has been shown to be involved in the pathogenesis of schizophrenia. The aim of our study was to assay the association of TCF4 single nucleotide polymorphisms (SNPs) with schizophrenia and the effect of these SNPs on phenotypic variability in schizophrenia in Southern Chinese Han Population. Methods: Four SNPs (rs9960767, rs2958182, rs4309482, and rs12966547) of TCF4 were genotyped in 1137 schizophrenic patients and 1035 controls in a Southern Chinese Han population using the improved multiplex ligation detection reaction (iMLDR) technique. For patients with schizophrenia, the severity of symptom phenotypes was analyzed by the five-factor model of the Positive and Negative Symptom Scale (PANSS). Cognitive function was assessed using the Brief Assessment of Cognition in Schizophrenia (BACS) scale. Results: The results showed that the genotypes and alleles of the three SNPs (rs2958182, rs4309482, and rs12966547) were not significantly different between the control group and the case group (all P > 0.05). rs9960767 could not be included in the statistics for the extremely low minor allele frequency. However, the genotypes of rs4309482 shown a potential risk in the positive symptoms (P = 0.04) and excitement symptoms (P = 0.04) of the five-factor model of PANSS, but not survived in multiple test correction. The same potential risk was shown in the rs12966547 in positive symptoms of the PANSS (P = 0.03). Conclusion: Our results failed to find the associations of SNPs (rs2958182, rs4309482, and rs12966547) in TCF4 with schizophrenia in Southern Chinese Han Population.

Large-Scale Brain Network Dynamics Provide a Measure of Psychosis and Anxiety in 22q11.2 Deletion Syndrome.

BACKGROUND: Prodromal positive psychotic symptoms and anxiety are two strong risk factors for schizophrenia in 22q11.2 deletion syndrome (22q11DS). The analysis of large-scale brain network dynamics during rest is promising to investigate aberrant brain function and identify potentially more reliable biomarkers. METHODS: We retrieved and examined dynamic properties of large-scale functional brain networks using innovation-driven coactivation patterns. The study included resting-state functional magnetic resonance scans from 78 patients with 22q11DS and 85 healthy control subjects. After group comparison of temporal brain network activation properties, functional signatures of prodromal psychotic symptoms and anxiety were extracted using multivariate partial least squares correlation. RESULTS: Patients with 22q11DS had shorter activation in cognitive brain networks, longer activation in emotion processing networks, and generally increased segregation between brain networks. The functional signature of prodromal psychotic symptoms confirmed an implication of cingulo-prefrontal salience network activation duration and coupling. Further, the functional signature of anxiety uncovered an implication of amygdala activation and coupling, indicating differential roles of dorsal and ventral subdivisions of the anterior cingulate and medial prefrontal cortices. Coupling of amygdala with the dorsal anterior cingulate and medial prefrontal cortices was promoting anxiety, whereas coupling with the ventral anterior cingulate and medial prefrontal cortices had a protective function. CONCLUSIONS: Using innovation-driven coactivation patterns for dynamic large-scale brain network analysis, we uncovered patterns of brain network activation duration and coupling that are relevant in clinical risk factors for psychosis in 22q11DS. Our results confirm that the dynamic nature of brain network activation contains essential function to develop clinically relevant imaging markers of psychosis vulnerability.

Using fMRI and machine learning to predict symptom improvement following cognitive behavioural therapy for psychosis.

Cognitive behavioural therapy for psychosis (CBTp) involves helping patients to understand and reframe threatening appraisals of their psychotic experiences to reduce distress and increase functioning. Whilst CBTp is effective for many, it is not effective for all patients and the factors predicting a good outcome remain poorly understood. Machine learning is a powerful approach that allows new predictors to be identified in a data-driven way, which can inform understanding of the mechanisms underlying therapeutic interventions, and ultimately make predictions about symptom improvement at the individual patient level. Thirty-eight patients with a diagnosis of schizophrenia completed a social affect task during functional MRI. Multivariate pattern analysis assessed whether treatment response in those receiving CBTp (n = 22) could be predicted by pre-therapy neural responses to facial affect that was either threat-related (ambiguous 'neutral' faces perceived as threatening in psychosis, in addition to angry and fearful faces) or prosocial (happy faces). The models predicted improvement in psychotic (r = 0.63, p = 0.003) and affective (r = 0.31, p = 0.05) symptoms following CBTp, but not in the treatment-as-usual group (n = 16). Psychotic symptom improvement was predicted by neural responses to threat-related affect across sensorimotor and frontal-limbic regions, whereas affective symptom improvement was predicted by neural responses to fearful faces only as well as prosocial affect across sensorimotor and frontal regions. These findings suggest that CBTp most likely improves psychotic and affective symptoms in those endorsing more threatening appraisals and mood-congruent processing biases, respectively, which are explored and reframed as part of the therapy. This study improves our understanding of the neurobiology of treatment response and provides a foundation that will hopefully lead to greater precision and tailoring of the interventions offered to patients.

Trauma infantil en esquizofrenia. Implicaciones en los síntomas psicóticos positivos y negativos / Childhood trauma and schizophrenia. Implications for positive and negative psychotic symptomsresumen

La relación entre trauma infantil (TI) y la psicosis está bien establecida y son diversas las teorías sobre los factores que median en esta relación. También son muchos los estudios que exploran la influencia del TI en el curso de la psicosis en distintas áreas. El objetivo de este estudio fue explorar la influencia del TI en la presencia e intensidad de los síntomas psicóticos positivos (SPP) y negativos (SPN) en pacientes con trastornos del espectro esquizofrénico. Se incluyeron un total de 45 pacientes con diagnóstico de esquizofrenia o trastorno esquizoafectivo. Se valoraron datos sociodemográficos, los antecedentes de TI mediante el Childhood Trauma Questionnaire, Short Form (CTQ-SF), así como la intensidad de los síntomas psicóticos positivos y negativos mediante la Positive and Negative Syndrome Scale (PANSS+ y -).De la totalidad de la muestra, 35 pacientes, el 77,8 %, habían padecido algún tipo trauma infantil; el 55,6%, negligencia emocional; el 48,9%, abuso emocional: el 46,7%, negligencia física y el 40,0%, abuso sexual. No encontramos correlación entre CTQ-SF y PANSS+ y sí una relación inversa ente CTQ-SF v PANSS- (Rho -0.300, p=0.045). A diferencia de otros estudios no encontramos una correlación entre el TI y los SPP, a excepción del abuso físico con el ítem de excitación, tal vez debido a la cronicidad de los pacientes de nuestra muestra. La correlación moderada e inversa entre el TI y los SPN sugerimos que podría deberse a que los síntomas psicóticos positivos y negativos surgirían de diátesis distintas. Los síntomas negativos estarían en relación con déficits de neurodesarrollo y no relacionados con el estrés, como se ha sugerido en los síntomas psicóticos positivos. Sin embargo, dado que es trata de un hallazgo poco replicado, es difícil establecer conclusiones claras.(AU)

The relationship between childhood trauma (CT) and psychosis is well established and theories about the factors mediating this relationship are diverse. CT is associated with a worse prognosis of psychosis The aim of this study was to explore the influence of childhood trauma on the presence and intensity of positive (PPS) and negative psychotic symptoms (NPS) in patients with schizophrenic spectrum disorders. Forty-five patients with a diagnosis of schizophrenia or schizo affective disorder were included. Sociodemographic data, childhood trauma history using the Childhood Trauma Questionnaire Short Form (CTQ-SF) and the intensity of positive and negative psychotic symptoms using the Positive and Negative Syndrome Scale (PANSS + and -), were valued. Of the total sample, 35 patients, 77.8%, had suffered some type of childhood trauma; 55.6%, emotional neglect; 48.9%, emotional abuse: 46.7%, physical neglect and 40.0%, sexual abuse. We did not find a correlation between CTQ-SF and PANSS+ and an inverse relationship between CTQ-SF v PANSS- (Rho -0.300, p=0.045). Unlike other studies, we did not find a correlation between CT and PPS, except for physical abuse with the excitation item, perhaps due to the chronicity of patients in our sample. The inverse corre lation between CT and NPS may be due to positive and negative psychotic symptoms arising from different diameters. NPS could be related to neurological development deficits and not related to stress, as suggested in PPS. However, since it is a finding with little replication, it is difficult to draw clear conclusions.(AU
