Circadian lighting effect for inpatients with schizophrenia: A prospective cohort study.

OBJECTIVES: In schizophrenia, nonspecific lighting likely causes sleep timing disturbances, leading to distress and poorer clinical status. However, the effect of exposure to circadian lighting on psychopathology outcome in schizophrenia remains unknown. Hence, this study aimed to develop such an intervention and investigate its impact on schizophrenia. METHODS: Twenty schizophrenia patients at a psychiatric nursing institute were monitored over 10 weeks, with assessments using the Brief Psychiatric Rating Scale (BPRS) and Mini-Mental State Examination (MMSE) conducted at baseline, weeks 3 (T1), 7 (T2), and 10 (T3). RESULTS: Circadian lighting significantly improved BPRS scores between T1-T2 (p < .05) and T1-T3 (p < .001), with affectivity scores also showing significant enhancements postintervention. Notably, female participants exhibited substantial improvements in BPRS scores from T1 to T3 (p < .01), while male participants demonstrated significant gains in MMSE scores from T1 to T2 (p < .01). CONCLUSIONS: Circadian lighting presents a promising intervention for improving psychiatric outcomes in schizophrenia, with distinct benefits observed across different psychopathological aspects and genders. These findings underscore the potential of lighting chronotherapy in psychiatric clinical practice and warrant further exploration in related research.

Changes in brain-derived neurotrophic factors in schizophrenic patients with spiritual psychoreligious therapy.

Objectives: To examine the effect of Spiritual Quranic Emotional Freedom Technique therapy on the level of brain-derived neurotrophic factor in schizophrenic patients. METHODS: The quasi-experimental study was conducted from August to December 2021 at the Polytechnic of Health, Kendari, Indonesia, and comprised patients of either gender aged >20 years who had been diagnosed with schizophrenia by psychiatrists using the text-revised version of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, had Brief Psychiatric Rating Scale score 50-60, and were part of the treatment programme at the polyclinic. They were divided into experimental group A and control group B. Patients in group A were given 30 days of Spiritual Quranic Emotional Freedom Technique therapy, while those in group B received only education about the spiritual therapy with the recommendation to listen to the Quran verses. A set of healthy controls memorizing the Quran was enrolled from the Islamic Boarding School, Kendari, and placed in group C. They were given education about the need to keep reading and learning the Quran. The intervention was done 2 times per week for 4 weeks. Serum brain-derived neurotrophic factor level for all groups and the Brief Psychiatric Rating Scale score for groups A and B were assessed at baseline and post-intervention. Data was analysed using SPSS 22. RESULTS: Of the 30 subjects, 16(53.3%) were females and 14(46.7%) were males. There were 11(36.7%) subjects aged 31-40 years. Each of the 3 groups had 10(33.3%) subjects. There was a significant decrease in Brief Psychiatric Rating Scale scores in groups A and B post-intervention (p<0.000). There was a significant increase in serum brain-derived neurotrophic factor levels post-therapy in groups A and C (p<0.001), while in group B it was not significant (p=0.500). CONCLUSIONS: Spiritual Quranic Emotional Freedom Technique therapy could enhance clinical improvement and brain function in schizophrenic patients.

Different psychopathological courses between chronic interictal psychosis and schizophrenia.

OBJECTIVE: The clinical course of interictal psychosis (IIP) has not yet been investigated. We aimed to compared the psychopathology and time-relevant indices between chronic IIP (CIIP) and schizophrenia (SC) METHODS: In this comprehensive psychopathological study, patients with chronic psychosis with and without epilepsy (127 with CIIP and 187 with SC) were compared. Psychopathology was measured using the Brief Psychiatric Rating Scale (BPRS): total, negative symptoms (NSs), positive symptoms (PSs), and anxiety-depressive symptoms (ADSs). Time-relevant indices included age at the time of evaluation, age at the onset of psychosis, and duration of psychosis. The psychopathology of psychosis types and time-relevant indices were analyzed using Pearson's correlation coefficient analysis of covariance. RESULTS: 　Age at the time of evaluation was significantly correlated with NS, and ADS scores. Age-relevant trajectories significantly interacted with psychosis types. As age advanced, patients with SC exhibited increased scores, whereas patients with CIIP often exhibited decreased (or unchanged) scores. Age at onset of psychosis was significantly correlated with NS and ADS outcomes in patients with CIIP, whereas it was not correlated in patients with SC. There were significant interactions between age at onset and psychosis types. Patients with early-onset CIIP exhibited higher NS and lower ADS scores, whereas patients with SC exhibited no particular trajectory. The duration of psychosis significantly interacted with the psychosis types in the BPRS total, NSs and PSs. As duration increased, patients with CIIP exhibited no significant relationship, whereas patients with SC exhibited significantly higher psychotic scores. CONCLUSION: Psychopathological courses differ between patients with CIIP and SC. Although patients with SC often exhibit deteriorations in psychotic symptoms, patients with CIIP exhibit no distinct deterioration. These findings can contribute psychiatric nosology, treatment strategies, and prediction outcomes.

The associations of psychopathology and metabolic parameters with serum bilirubin levels in patients with acute-episode and drug-free schizophrenia: a 5-year retrospective study using an electronic medical record system.

BACKGROUND: The oxidative system plays an important role in the pathogenesis of schizophrenia. Inconsistent associations were found between hyperbilirubinemia and psychopathology as well as glycolipid metabolism in patients with schizophrenia at different episodes. This current study aimed to examine these associations in patients with acute-episode and drug-free (AEDF) schizophrenia. METHODS: This is a retrospective study using 5 years of data from May 2017 to May 2022 extracted from the electronic medical record system of Chaohu Hospital of Anhui Medical University. Healthy controls (HCs) from the local medical screening center during the same period were also included. Participants' data of the bilirubin levels [total bilirubin (TB), conjugated bilirubin (CB), unconjugated bilirubin (UCB)], glycolipid metabolic parameters and the score of the Brief Psychiatric Rating Scale (BPRS) were collected. RESULTS: A total of 1468 case records were identified through the initial search. After screening, 89 AEDF patients and 100 HCs were included. Compared with HCs, patients had a higher CB level, and lower levels of glycolipid metabolic parameters excluding high density lipoprotein-cholesterol (HDL-C) (all P < 0.001). Binary logistic regression analyses revealed that high bilirubin levels in the patients were independently associated with higher total and resistance subscale scores of BPRS, a higher HDL-C level, and lower total cholesterol and triglyceride levels (all P < 0.05). CONCLUSION: Bilirubin levels are elevated in patients with AEDF schizophrenia. Patients with high bilirubin levels have more severe psychopathology and relatively optimized glycolipid metabolism. In clinical practice, regular monitoring of bilirubin levels in this patient population should be carried out.

Revisiting delusion subtypes in schizophrenia based on their underlying structures.

A clear understanding of the pathophysiology of schizophrenia and related spectrum disorders has been limited by clinical heterogeneity. We investigated whether relative severity and predominance of one or more delusion subtypes might yield clinically differentiable patient profiles. Patients (N = 286) with schizophrenia spectrum disorders (SSD) completed the 21-item Peters et al. Delusions Inventory (PDI-21). We performed factor analysis followed by k-means clustering to identify delusion factors and patient subtypes. Patients were further assessed via the Brief Psychiatric Rating Scale, Brief Negative Symptom Scale, Digit Symbol and Digit Substitution tasks, use of cannabis and tobacco, and stressful life events. The overall patient sample clustered into subtypes corresponding to Low-Delusion, Grandiose-Predominant, Paranoid-Predominant, and Pan-Delusion patients. Paranoid-Predominant and Pan-Delusion patients showed significantly higher burden of positive symptoms, while Low-Delusion patients showed the highest burden of negative symptoms. The Paranoia delusion factor score showed a positive association with Digit Symbol and Digit Substitution tasks in the overall sample, and the Paranoid-Predominant subtype exhibited the best performance on both tasks. Grandiose-Predominant patients showed significantly higher tobacco smoking severity than other subtypes, while Paranoid-Predominant patients were significantly more likely to have a lifetime diagnosis of Cannabis Use Disorder. We suggest that delusion self-report inventories such as the PDI-21 may be of utility in identifying sub-syndromes in SSD. From the current study, a Paranoid-Predominant form may be most distinctive, with features including less cognitive impairment and a stronger association with cannabis use.

Extension, translation and preliminary validation of the Northoff Scale for Subjective Experience in Catatonia (NSSC).

BACKGROUND: In the last two decades, much neuroscientific research has been done on the pathomechanisms of catatonia. However, catatonic symptoms have mainly been assessed with clinical rating scales based on observer ratings. Although catatonia is often associated with strong affective reactions, the subjective domain of catatonia has simply been neglected in scientific research. METHODS: The main objective of this study was to modify, extend and translate the original German version of the Northoff Scale for Subjective Experience in Catatonia (NSSC) and to examine its preliminary validity and reliability. Data were collected from 28 patients diagnosed with catatonia associated with another mental disorder (6A40) according to ICD-11. Descriptive statistics, correlation coefficients, internal consistency and principal component analysis were employed to address preliminary validity and reliability of the NSSC. RESULTS: NSSC showed high internal consistency (Cronbach's alpha = 0.92). NSSC total scores were significantly associated with Northoff Catatonia Rating Scale (r = 0.50, p < .01) and Bush Francis Catatonia Rating Scale (r = 0.41, p < .05) thus supporting its concurrent validity. There was no significant association between NSSC total score and Positive and Negative Symptoms Scale total (r = 0.26, p = .09), Brief Psychiatric Rating Scale (r = 0.29, p = .07) and GAF (r = 0.03, p = .43) scores. CONCLUSION: The extended version of the NSSC consists of 26 items and was developed to assess the subjective experience of catatonia patients. Preliminary validation of the NSSC revealed good psychometric properties. NSSC is a useful tool for everyday clinical work to assess the subjective experience of catatonia patients.

Fathering children aged from 2 to 10: psychometric properties of the IFI-BR-27 / Paternidade com filhos entre 2 e 10 anos de idade: propriedades psicométricas do IFI-BR-27 / Paternidad con hijos de entre 2 y 10 años: propiedades psicométricas del IFI-BR-27

The Inventory of Father Involvement (IFI) was developed to examine paternal involvement among men with children from 5 to 10 years of age. However, father involvement affects child development starting in the child's infancy. In Brazil, a revised version of the instrument (called the IFI-BR-27) was developed to use with fathers of children in a wider age group (2 to 10 years). Thus, in this study we aimed to investigate evidence for validity of this revised version based on internal structure, measurement invariance, and evidence of convergent validity. For this purpose, 572 Brazilian fathers completed a sociodemographic questionnaire, the IFI-BR-27, and either the Father Engagement Questionnaire (FEQ; for fathers of children in early childhood education settings) or the Inventory of Parenting Practices (IPP; for fathers of children in elementary school). Results of confirmatory factor analyses indicated the plausibility of a second-order internal structure for the IFI-BR-27 (χ 2 / df = 3.526; CFI = .937; TLI = .929; RMSEA = .066). Composite reliability for the nine factors varied from .65 to .84. Invariance analyses indicated that the structure is independent of the child's educational setting. Evidence of convergent validity was also found ( r = .67 - FEQ; r = .58 - IPP). Therefore, the IFI-BR-27 is an adequate tool to assess the quality of father involvement for fathers of children in preschool or elementary school. The IFI-BR-27 can contribute to further scientific research, aiding in longitudinal studies, as well as helping professionals to evaluate and encourage specific dimensions of father involvement.(AU)

O Inventory of Father Involvement (IFI) foi desenvolvido para avaliar o envolvimento paterno de homens com filhos de 5 a 10 anos. No entanto, envolvimento paterno afeta o desenvolvimento de crianças desde a primeira infância. No Brasil, uma versão revisada dessa medida (chamada de IFI-BR-27) foi desenvolvida para uso com pais de crianças em uma faixa etária mais ampla (2 a 10 anos). O objetivo deste estudo foi, portanto, investigar evidências de validade dessa versão revisada com base na estrutura interna, invariância de medida e evidências de validade convergente. Para isso, 572 pais brasileiros preencheram um questionário sociodemográfico, o IFI-BR-27 e o Questionário de Engajamento Paterno (QEP; para pais com filhos no Ensino Infantil) e o Inventário de Práticas Parentais (IPP; para pais com filhos no Ensino Fundamental 1). Os resultados de análises fatoriais confirmatórias indicaram a plausibilidade de uma estrutura interna de segunda ordem para o IFI-BR-27 (χ 2 / gl = 3,526; CFI = 0,937; TLI = 0,929; RMSEA = 0,066). A confiabilidade composta para os nove fatores variou de 0,65 a 0,84. Análises de invariância indicaram que a estrutura é independente do ciclo escolar da criança. Também foram encontradas evidências de validade convergente ( r = 0,67 - QEP; r = 0,58 - IPP). Assim, considera-se o IFI-BR-27 uma medida adequada para avaliar a qualidade do envolvimento paterno de pais de crianças do Ensino Infantil ao Fundamental 1. O IFI-BR-27 poderá contribuir para melhorias científicas, viabilizando estudos longitudinais e ajudando profissionais a avaliar e promover dimensões específicas do envolvimento paterno.(AU)

El Inventory of Father Involvement (IFI) se desarrolló para evaluar la participación paterna en la crianza de hijos de entre 5 y 10 años de edad. Es sabido que la participación paterna contribuye al desarrollo infantil desde la primera infancia. En Brasil, una versión brasileña de este instrumento (la IFI-BR-27) se desarrolló para aplicarse a padres con hijos de un grupo de edad más amplio (de 2 a 10 años). Este estudio tuvo por objetivo comprobar evidencia de validez de esta versión revisada con base en la estructura interna, la invariancia del instrumento y la evidencia de validez convergente. Para ello, 572 padres brasileños completaron un cuestionario sociodemográfico, el IFI-BR-27 y el Cuestionario de Involucramiento Paterno (CIP; para padres de niños en el jardín de infantes) y el Inventario de Prácticas Parentales (IPP; para padres de niños en la primaria). Los resultados de los análisis factoriales confirmatorios indicaron la plausibilidad de una estructura interna de segundo orden para el IFI-BR-27 (χ 2 / gl = 3,526; CFI = 0,937; TLI = 0,929; RMSEA =0,066). La confiabilidad compuesta para los nueve factores varió de 0,65 a 0,84. Los análisis de invariancia indicaron que la estructura es independiente del ciclo educativo del niño. También se encontró evidencia de validez convergente ( r =0,67 - CIP; r = 0,58 - IPP). Por lo tanto, el IFI-BR-27 es un instrumento adecuado para evaluar la calidad de participación paterna de padres con hijos en edad preescolar o en la primaria. El IFI-BR-27 permitirá un mayor desarrollo científico, permitiendo estudios longitudinales y ayudando a los profesionales a evaluar y fomentar dimensiones específicas de participación paterna.(AU)

Case control study: G-allele of rs4244165 in JAK1 gene correlated with high-level brief psychiatric rating scale in bipolar patients.

Bipolar disorder (BD) is a chronic and clinically complex disease, characterized by pathological disturbances in mood and energy. Cytokines can access the brain and their signaling pathways affect brain functions, such as neurotransmitter metabolism, neuroendocrine function, neural/synaptic plasticity, and mood neural circuitry. JAK 1 is the most common phosphorylation protein combined with the tyrosine kinase cytokine receptors; therefore, we investigated the association between the Janus family kinase 1 (JAK1) gene polymorphisms (rs2780895, rs4244165, and rs17127024) and susceptibility to BD. The case study population included 93 patients diagnosed with BD and 112 healthy controls, selected from the central coastal region of Tunisia. Polymerase chain reaction-restriction fragment length polymorphism was used to investigate these 3 JAK1 polymorphisms. We compared the sociodemographic and clinical parameters of 3 genotypes of this single nucleotide polymorphisms rs2780895, rs4244165, and rs17127024 of the JAK1 gene. The frequencies of the 3 genotypes were similar in the patient and control groups. One-way analysis of variance revealed a significant variation in rs4244165. After hospitalization, the average of the brief psychiatric rating scale score was significantly higher for the wild-type GG genotype than that for the double-mutation TT genotype (31.23% vs 22.85%, P = .043). The least significant difference post hoc test also showed a significant difference between the GG and TT genotypes at both hospital admission (P = .001) and after hospitalization (P = .012), with the GG genotype being associated with a higher brief psychiatric rating scale score. Haplotypic analysis revealed that the wild-type haplotype with the highest frequency (46.62%) was CTG. Our results showed no association between the 3 studied positions and bipolar disorder. However, the G-allele of rs4244165 in JAK1 is associated with the highest level of the brief psychiatric rating scale in patients with bipolar disorder. The JAK/signal transducer and activator of transcription pathway is an interesting therapeutic route that requires further investigations. Studying their regulatory regions can provide a clearer picture of all the interactions involved in the regulation of genetic expression in response to treatment.

Time will tell: Associations between unbalanced time perspectives and symptom severity in individuals with schizophrenia spectrum disorders.

Patients with schizophrenia spectrum disorder (SSD) experience disrupted temporality on the immediate timescale. However, insufficient information is available for longer time frames, and the interaction of temporal perspectives with the clinical manifestations of SSD is unknown. We explored the association between unbalanced time perspectives and symptom severity. Thirty-seven Italian mental health services participating in the DiAPAson project recruited 620 patients with DSM-5 SSD (68 % males, mean age = 41.3 ± 9.5 years). Time perspective biases were measured using the Deviation from the Balanced Time Perspective-revisited (DBTP-r) indicator, based on Zimbardo Time Perspective Inventory (ZTPI) scores. Psychiatric symptoms were assessed using the Brief Psychiatric Rating Scale (BPRS) and Brief Negative Symptoms Scale (BNSS). Preliminary analyses examined the associations between ZTPI/DBTP-r and BPRS/BNSS total scores. In secondary analyses, we first tested the associations between the ZTPI/DBTP-r and BPRS/BNSS subscales and then compared ZTPI differences between patients with and without hallucinations, delusions, and conceptual disorganisation. Statistical significance was set at Holm-Bonferroni corrected p < 0.05. Low-to-moderate positive correlations were found between the DBTP-r and BPRS/BNSS total scores (r = 0.29/0.22). The strongest associations were between DBTP-r/ZTPI_Past-Negative and anxiety/depression (r = 0.34/0.36), followed by DBTP-r/ZTPI_Present-Fatalistic with thought disturbances (r = 0.22/0.20). DBTP-r was associated with BNSS anhedonia and avolition (r = 0.21/0.24). DBTP-r was higher in patients with hallucinations (ES = 0.391) and conceptual disorganisation (ES = 0.397) than in those without these symptoms. Unbalanced time perspective was positively associated with the severity of primary and secondary SSD features. These findings provide a rationale for empirical tests focused on balancing time perspectives in patients with SSD.

Potential role between inflammatory cytokines and Tie-2 receptor levels and clinical symptoms in patients with first-episode schizophrenia.

BACKGROUND: Schizophrenia (SCZ) is associated with chronic low-grade inflammation, which may be involved in the underlying pathological mechanism of the disease and may influence patient prognosis. We evaluated the differences in serum cytokine and Tie-2 receptor levels between patients with first-episode SCZ and healthy controls and explored the correlation thereof with clinical symptoms. METHODS: Seventy-six participants were recruited for the present study, including 40 patients with first-episode SCZ and 36 healthy controls. Positive and Negative Syndrome Scale (PANSS) and Brief Psychiatric Rating Scale (BPRS) scores, demographic data, and blood samples were collected at baseline. A hypersensitive Meso Scale Discovery (MSD) electrochemiluminescence assay system was used to measure cytokine and Tie-2 receptor levels. Spearman's correlation and stepwise linear regression were used to analyze the data. RESULTS: Serum interleukin-1ß and -4 levels were significantly increased, and Tie-2 levels were significantly decreased, in first-episode SCZ patients as compared to healthy controls. IL-1ß levels were positively correlated with total BPRS scores, resistance subscores, and PANSS positive subscores. Furthermore, IL-1ß levels were negatively correlated with Tie-2 receptor expression levels. Stepwise linear regression analysis demonstrated that IL-1ß levels correlated positively with PANSS positive subscores and BPRS total scores. PANSS negative subscores, general psychopathology subscores, and PANSS total scores had positive effects on the Tie-2 receptor. Receiver operating characteristic (ROC) curve analysis showed that IL-1ß and Tie-2 were highly sensitive and specific for predicting first-episode SCZ symptoms and achieving an area under the ROC curve of 0.8361 and 0.6462, respectively. CONCLUSION: Our results showed that patients with first-episode SCZ have low-grade inflammation. IL-1ß and Tie-2 receptors may be important mediators between inflammation and vascular dysfunction in patients with SCZ and may underlie the increased cardiovascular disease in this population. TRIAL REGISTRATION: The clinical trial registration date was 06/11/2018, registration number was chiCTR1800019343.

Longitudinal Factor Structure of the Brief Psychiatric Rating Scale Among Incident Cases of Schizophrenia Attending a Nigerian Hospital.

Background: Schizophrenia, from its early conceptualization, has been described in distinct clinical subtypes. However, these categories were found not to be stable phenotypes over time, hence the dimensional option, whereas at cross-sectional level, the dimensions of psychopathology have been replicated across studies; there is dearth of data on the longitudinal stability of the factor structure of the symptoms of schizophrenia in African populations. Aim: This study examined the longitudinal stability of the factor structure of the 18-item Brief Psychiatric Rating Scale (BPRS) across intervals of 16-week naturalistic treatment follow-up. Patients and Methods: Consecutive incident cases that fulfilled the criteria for schizophrenia were recruited into the study. After a baseline assessment, 160 incident cases of schizophrenia were followed up 4 weekly for indicators of symptomatic outcome for 16 weeks. The Brief Psychiatric Rating Scale (BPRS) assessments were conducted in clinical interviews and with the Scale for Assessment of Negative Symptoms (SANS). Five BPRS assessments were made across the monthly intervals of follow-up. Exploratory factor analyses (EFA) using maximum likelihood extraction and varimax rotation with Kaiser normalization was used to extract the factors. Results: A four-factor structure was found at baseline, namely negative, positive, depressive/anxiety, and manic symptom dimensions. From week 4, the manic and anxiety/depression dimensions remained invariant over time, while negative and positive symptoms merged into a psychosis dimension that was invariant. Conclusion: The persistence of the mood dimensions supports the DSM-5 recommendation to include these dimensions in the assessment of schizophrenia psychopathology. The longitudinal emergence and invariance of the psychosis factor echo the idea of unitary psychosis and, along with the prominence of mood dimensions over time, reflect recent molecular genetic findings about the sharing of genes by schizophrenia and mood disorders.

Correlation between elevated serum interleukin-1ß, interleukin-16 levels and psychiatric symptoms in patients with schizophrenia at different stages.

BACKGROUND: There is increasing evidence that immune dysfunction plays an important role in the pathogenesis of schizophrenia. Meso Scale Discovery (MSD) is bioanalytical method, which can detect serum inflammatory factors in patients. MSD has higher sensitivities, capturing a narrower range of proteins compared to other methods typically used in similar studies. The present study was aimed to explore the correlation between the levels of serum inflammatory factors and psychiatric symptoms in patients with schizophrenia at different stages and investigate a wide panel of inflammatory factors as independent factors for the pathogenesis of schizophrenia. METHODS: We recruited 116 participants, including patients with first-episode schizophrenia (FEG, n = 40), recurrence patients (REG, n = 40) with relapse-episode schizophrenia, and a control group (healthy people, HP, n = 36). Patients are diagnosed according to the DSM -V. The plasma levels of IFN-γ, IL-10, IL-1ß, IL-2, IL-6, TNF-α, CRP, VEGF, IL-15, and IL-16 were tested by the MSD technique. Patient-related data was collected, including sociodemographic data, positive and negative symptom scale (PANSS), and brief psychiatric rating scale (BPRS) and subscale scores. The independent sample T test, χ2 test, Analysis of covariance (ANCOVA), the least significant difference method (LSD), Spearman's correlation test, binary logistic regression analysis and ROC curve analysis were used in this study. RESULTS: There were significant differences in serum IL-1ß (F = 2.37, P = 0.014) and IL-16 (F = 4.40, P < 0.001) levels among the three groups. The level of serum IL-1ß in the first-episode group was significantly higher than in the recurrence group (F = 0.87, P = 0.021) and control group (F = 2.03, P = 0.013), but there was no significant difference between the recurrence group and control group (F = 1.65, P = 0.806). The serum IL-16 levels in the first-episode group (F = 1.18, P < 0.001) and the recurrence group (F = 0.83, P < 0.001) were significantly higher than in the control group, and there was no significant difference between the first-episode group and the recurrence group (F = 1.65, P = 0.61). Serum IL-1ß was negatively correlated with the general psychopathological score (GPS) of PANSS (R=-0.353, P = 0.026). In the recurrence group, serum IL-16 was positively correlated with the negative score (NEG) of the PANSS scale (R = 0.335, P = 0.035) and negatively correlated with the composite score (COM) (R=-0.329, P = 0.038). In the study, IL-16 levels were an independent variable of the onset of schizophrenia both in the first-episode (OR = 1.034, P = 0.002) and recurrence groups (OR = 1.049, P = 0.003). ROC curve analysis showed that the areas under IL-16(FEG) and IL-16(REG) curves were 0.883 (95%CI:0.794-0.942) and 0.887 (95%CI:0.801-0.950). CONCLUSIONS: Serum IL-1ß and IL-16 levels were different between patients with schizophrenia and healthy people. Serum IL-1ß levels in first-episode schizophrenia and serum IL-16 levels in relapsing schizophrenia were correlated with the parts of psychiatric symptoms. The IL-16 level may be an independent factor associating with the onset of schizophrenia.

"Feeling shattered and ephemeral": How do positive and negative symptoms affect self-concept clarity among individuals experiencing psychosis?

PURPOSE: Incoherence in sense of self in schizophrenia may mask individuals' ability to perceive reality accurately, and cause them to feel alienated from themselves and others. This descriptive correlational study investigates the relationship between positive and negative symptoms in relation to self-concept clarity (SCC) in schizophrenia. METHOD: A sample of 200 inpatients with schizophrenia were recruited to complete the Self-Concept Clarity Scale and were rated on the Brief Psychiatric Rating Scale (BPRS-version 4.0). RESULTS: A strong inverse correlation between positive and negative symptoms in relation to SCC (r = 0.242, P < 0.001, and r = 0.225, P = 0.001, respectively). CONCLUSION: The overall BPRS scores were identified as independent precursors of low SCC.

BPRS domains, items and subgroups analyses, and CGI-I ratings in pooled data from non-interventional studies of aripiprazole once-monthly in schizophrenia (REACT study).

BACKGROUND: Patients with schizophrenia may benefit from treatment with long-acting injectable (LAI) formulations of antipsychotics. Aripiprazole once-monthly (AOM) is an LAI that was tested in two non-interventional studies in Germany and Canada. METHODS: Here, we report on analyses of pooled data from the two non-interventional studies. Patients were treated with AOM under real-life conditions. Data were analyzed for a timeframe of 6 months. We analyzed data on Brief Psychiatric Rating Scale (BPRS) domains and items, BPRS total scores in various patient subgroups (male vs. female patients, patients with disease duration ≤ 5 years and > 5 years, patients with different levels of disease severity at baseline), Clinical Global Impression - Improvement (CGI-I) ratings for the total population and subgroups, and comorbidities for the total population. RESULTS: Data from 409 patients were included. 65.5% of the patients had comorbidities. Improvements were found in all BPRS domains and items. Furthermore, improvements were similar for male and female patients, patients with disease duration ≤ 5 years and > 5 years, and across different levels of disease severity at baseline. Numerically, more favorable results were found for younger patients, female patients, and those with shorter disease duration. CONCLUSIONS: AOM can be an effective treatment in the broad range of patients, across sexes, regardless of patient age and duration of disease, independently of disease severity, and across symptoms.

Time perspective affects daily time use and daily functioning in individuals with Schizophrenia Spectrum Disorders: Results from the multicentric DiAPAson study.

Time perspective (TP) influences various aspects of human life. We aimed to explore the associations between TP, daily time use, and levels of functioning among 620 patients (313 residential patients and 307 outpatients) with a diagnosis of Schizophrenia Spectrum Disorders (SSD) recruited from 37 different centres in Italy. The Brief Psychiatric Rating Scale and the Specific Levels of Functioning (SLOF) were used to assess psychiatric symptoms severity and levels of functioning. Daily time use was assessed using an ad hoc paper and pencil Time Use Survey. The Zimbardo Time Perspective Inventory (ZTPI) was used to assess TP. Deviation from Balanced Time Perspective (DBTP-r) was used as an indicator of temporal imbalance. Results showed that the amount of time spent on non-productive activities (NPA) was positively predicted by DBTP-r (Exp(ß): 1.36; p .003), and negatively predicted by the Past-Positive (Exp(ß): 0.80; p .022), Present-Hedonistic (Exp(ß): 0.77; p .008), and Future (Exp(ß): 0.78; p .012) subscales. DBTP-r significantly negatively predicted SLOF outcomes (p .002), and daily time use, in particular the amount of time spent in NPA and Productive Activities (PA), mediated their association. Results suggested that rehabilitative programs for individuals with SSD should consider fostering a balanced time perspective to reduce inactivity, increase physical activity, and promote healthy daily functioning and autonomy.

Hope and resilience among patients affected by unipolar and bipolar depression.

BACKGROUND: Mood disorders, including unipolar and bipolar depression, are disabling mental conditions and patients' full-functional recovery may be challenging. Hope and Resilience are relevant factors in the framework of personal recovery and it is of interest to explore their association with the severity of depressive illness and other variables, including suicidality. METHODS: in this cross-sectional study, 69 patients affected by unipolar (n = 31) and bipolar depression (n = 38) have been recruited and information about their sociodemographics, clinical characteristics were collected as well as the following assessment has been performed: BPRS (Brief Psychiatric Rating Scale); HAMD ( Hamilton Rating Scale for Depression); MADRS (Montgomery Asberg Depression rating scale); HADS (Hospital Anxiety and Depression Scale); SSI (Scale for Suicide Ideation); Synder (The Adult Hope Scale); CD-Risk (The Connor-Davidson Resilience Scale). RESULTS: patients affected by bipolar depression reported significantly higher level of psychopathological issues (BPRS) as well as higher scores of depressive and anxious symptoms (MADRS and HADS), suicidality (SSI). Also, bipolar depression patients reported lower levels of hope (Synder) and resilience (CD-Risk), with hope and resilience levels positively correlated each other, and inversely correlated to psychopathology and psychopathology, depressive and suicidal symptoms, respectively. CONCLUSIONS: these findings suggested that bipolar depression is characterized by higher clinical severity and lower levels of hope and resilience. Specific psycho-educational and psychotherapeutic interventions should be promoted to increase levels of hope and resilience in mood disorders, especially in bipolar depression.

The Course of Psychiatric Symptoms During Remand Imprisonment.

Imprisonment may pose a risk for unintended effects such as deterioration of psychiatric symptoms. Therefore, it is pivotal to understand the relation between imprisonment and the course of psychiatric symptoms, but previous studies are inconclusive. The current study followed up the psychiatric symptoms of newly admitted remand prisoners to one Dutch remand prison using the Brief Psychiatric Rating Scale (BPRS) and also studied possible related pre-existing variables. On average we found an overall slight-yet clinically marginal-improvement of psychiatric, in particular affective symptoms. One in three prisoners deteriorated and prisoners with psychotic disorders less often deteriorated. Other variables were not related. Overall, psychiatric symptoms remain stable over time during early remand imprisonment independent of most psychiatric disorders. The context in the Dutch prison studied appears to be adequately organized in terms of handling psychiatric stability, but we notice that prison contexts may vary to a large extend.

Brief Solution Focused Therapy on schizophrenia: A preliminary study of family characteristics and psychopathology.

Family therapy for schizophrenia has been demonstrated to be effective and is recommended by international clinical guidelines. Reviews of family therapy research conclude that interventions may prevent relapse of the disease, when symptoms are already reduced under psychotropic medication, by reducing family factors associated with relapse. The purpose of this study was to examine the effectiveness of Brief Solution Focused therapy (BSFT) in patients with schizophrenia focusing on the impact of change in family characteristics such as cohesion, conflict, organization and control on patients' psychopathology measured with BPRS. Thirty patients diagnosed with schizophrenia were randomly assigned to the control or intervention group. The intervention group received treatment according to the BSFT model, whereas the control group received the standard care for schizophrenia. The BSFT is a future-oriented psychotherapy model which encourages clients to focus on ''change-talking'' instead of ''problem-talking'' and on instances where a successful solution has been achieved. The intervention was consisted of 5 sessions delivered in 3 months. Main outcomes were patient-rated family characteristics measured by the Family Environment Scale (FES), and psychiatrist-rated symptom severity measured with the Brief Psychiatric Rating Scale (BPRS). The two groups did not differ in terms of age, sex, number of relapses, previous hospital admissions, and BPRS score at baseline. At the end of treatment compared to baseline there was a reduction of the BPRS score in the intervention group (p<0.001) whereas no statistically significant changes were noticed in the control group after 3 months. Also, following treatment, patients in the intervention group displayed reduced scores on the Conflict FES scale (p=0.001) accompanied by increased scores on the Cohesion (p=0.004), Expressiveness (p=0.004), and Active Recreational subscales (p=0.001) according to patient's perspective. These preliminary findings suggest that BSFT in patients with schizophrenia, appears to be effective in altering the global properties of the whole family system, specifically cohesion, conflict, organization and control which, in turn, have an impact on reducing patient psychopathology.

Sistema de avaliação de testes psicológicos: histórias contadas e não contadas / Psychological test evaluation system: stories told and untold / Sistema de evaluación de tests psicológicos: historias contadas y no contadas

O Sistema de Avaliação de Testes Psicológicos (SATEPSI) recebeu notoriedade entre brasileiros e estrangeiros por oferecer um complexo sistema de qualificação dos testes psicológicos, pouco visto em âmbito mundial. Sua elaboração dependeu de uma autarquia, que o financiou, normatizou e o mantém, mas também de pesquisadores docentes de avaliação psicológica, que trouxeram a expertise da área para que houvesse o pleno estabelecimento de seus parâmetros. Passadas duas décadas de seu lançamento, o SATEPSI foi tema de artigos, capítulos, lives e diálogos digitais, nos quais foram destaque, de modo geral, as Resoluções do Conselho Federal de Psicologia, que o normatiza, e seus impactos para a área de avaliação psicológica - como, por exemplo, o aumento do número de pesquisas e de testes brasileiros qualificados. O que se pretende neste artigo é mencionar sua construção, à luz dos autores que vivenciaram o SATEPSI em funções e tempos distintos. Atenção especial será dada aos Métodos Projetivos, cuja história ainda é pouco revelada.(AU)

The system to evaluate psychological tests (Satepsi) received notoriety among Brazilians and foreigners for offering a complex system of qualification of psychological tests, which is rarely seen worldwide. Its development depended on an autarchy (which financed, standardized, and maintains it) and on researchers teaching psychological assessment, who brought their expertise to the area so its parameters could be fully established. After two decades of its launch, Satepsi was the subject of articles, chapters, lives, and digital dialogues, which usually highlighted the Resolutions of the Federal Council of Psychology that normatize psychological evaluation and their impacts, such as the increase in the number of qualified Brazilian tests. This study aims to mention its construction in the light of the authors who experienced Satepsi in different functions and times, giving special attention to Projective Methods, whose history remains to be shown.(AU)
