It has been shown that various aspects of clinical manifestation schizophrenia are strongly related to social functioning. However, it remains unknown as whether similar factors predict functioning at stages psychosis. Therefore, the present study aimed compare effects interconnections between domains psychopathology and neurocognition on in people during acute phase psychosis those remission positive disorganization symptoms using a network analysis.Two independent samples individuals with spectrum disorders were enrolled (89 inpatients 90 outpatients symptoms). Clinical assessment covered levels functioning, positive, negative depressive symptoms. Cognition was recorded Repeatable Battery for Assessment Neuropsychological Status (RBANS). Data analyzed by means analysis. Two separate networks symptoms, cognition (i.e., patients remitted schizophrenia) compared respect measures centrality (betweenness, closeness, strength, expected influence) edge weights.In both networks, majority metrics (expected influence, closeness) had highest values RBANS scores attention (the sum from two tasks, i.e., digit span coding) immediate memory.

Abstract Background Few studies have examined the long-term outcomes of first-episode psychosis (FEP) among patients beyond symptomatic and functional remission. This study aimed to broaden scope outcome indicators by examining relationships between 12 FEP at 20.9 years after their initial diagnosis. Methods At follow-up, 220 out 550 original underwent a new assessment. Twelve were assessed via semistructured interviews complementary scales: symptom severity, impairment, personal recovery, social disadvantage, physical health, number suicide attempts, episodes, current drug use, dose-years antipsychotics (DYAps), cognitive motor abnormalities, DSM-5 final The these measures investigated using Spearman’s correlation analysis exploratory factor analysis, while specific connections ascertained network analysis. Results significantly correlated; specifically, functioning, recovery showed strongest correlations. Exploratory revealed two factors, with 11 loading on first factor.

Abstract Background Negative symptoms of schizophrenia are linked with poor functioning and quality life. Therefore, appropriate measurement tools to assess negative needed. The NIMH-MATRICS Consensus defined five domains for symptoms, which Brief Symptom Scale (BNSS) covers. Methods We used the COSMIN guidelines systematic reviews evaluate psychometric data BNSS scale as a Clinician-Rated Outcome Measure (ClinROM). Results search strategy resulted in inclusion 17 articles. When using risk bias checklist, there was generally good reporting structural validity hypothesis testing. Internal consistency, reliability cross-cultural were poorer quality. ClinROM development content showed inadequate results. According updated criteria properties, validity, internal consistency interrater results, while testing Cross-cultural test-retest indeterminate. GRADE approach moderate grade. Conclusions can potentially recommend use concise tool rate symptoms. Due weaknesses certain further validations warranted.

The conceptualization of negative symptoms (NS) in schizophrenia is still controversial. Recent confirmatory factor-analytic studies suggested that the bi-dimensional model (motivational deficit [MAP] and expressive [EXP]) may not capture complexity NS structure, which could be better defined by a five-factor (five domains) or hierarchical domains as first-order factors, MAP EXP, second-order factors).

This study compares the clinical features of Treatment-Resistant Schizophrenia (TRS) and Non-Treatment-Resistant (NTRS) using network analysis. We recruited 511 patients, dividing them into TRS (N = 269) NTRS 242) groups. Eight scales were used: Positive Negative Syndrome Scale (PANSS), Symptom Assessment (SAPS), for Symptoms (SANS), Simpson-Angus (SAS), Abnormal Involuntary Movements (AIMS), Barnes Akathisia Rating (BARS), Calgary Depression (CDSS), Global Functioning (GAF). Demographic data analyzed T-tests Chi-square tests. Network analysis was then applied to compare features. Significant differences found in overall architectures (S 1.396, p < 0.002) edge weights (M 0.289, 0.009) networks. Nine edges (p 0.05) five nodes 0.01) differed, indicating a correlation between symptoms two core linked social functions through both positive (SAPS) negative while related general psychopathological (PANSS-G).
