The landscape of schizophrenia on twitter

Introduction People with schizophrenia experience higher levels of stigma compared with other diseases. The analysis of social media content is a tool of great importance to understand the public opinion toward a particular topic. Objectives The aim of this study is to analyse the content of social media on schizophrenia and the most prevalent sentiments towards this disorder. Methods Tweets were retrieved using Twitter’s Application Programming Interface and the keyword “schizophrenia”. Parameters were set to allow the retrieval of recent and popular tweets on the topic and no restrictions were made in terms of geolocation. Analysis of 8 basic emotions (anger, anticipation, disgust, fear, joy, sadness, surprise, and trust) was conducted automatically using a lexicon-based approach and the NRC Word-Emotion Association Lexicon. Results Tweets on schizophrenia were heterogeneous. The most prevalent sentiments on the topic were mainly negative, namely anger, fear, sadness and disgust. Qualitative analyses of the most retweeted posts added insight into the nature of the public dialogue on schizophrenia. Conclusions Analyses of social media content can add value to the research on stigma toward psychiatric disorders. This tool is of growing importance in many fields and further research in mental health can help the development of public health strategies in order to decrease the stigma towards psychiatric disorders.

Introduction: Challenged by the lack of collaboration between treatment sectors in psychiatric care in Germany, a legal basis for the implementation of Stationsäquivalente Behandlung (StäB), a programme for crisis resolution and home treatment (CRHT), was formed in 2017. It offers intensive care to patients with severe mental illness in their own living environments, carried out by a team of diverse professionals. Objectives: The present analysis is the first to evaluate the CRHTprogram that has been established in the greater Munich area in 2018. Methods: Qualitative and quantitative data were collected within the framework of a mixed-methods-analysis. Records of all patients (N=139) included in the CRHT over a thirteen-month period ('18-'19) were examined regarding sociodemographic, clinical parameters, and treatment data. A focus group with StäB-employees (N=8) and individual interviews with patients (N=10) were conducted, then transcribed, and analysed using thematic analysis. Results: 139 patients (74% female) were treated in 164 cases for 38 days on average. Main diagnoses were schizophrenic diseases (43%) and mood disorders (35%), with patients ranging from markedly to severely ill (mean CGI-S: 5.8). 9.4% were in postpartum. Qualitative analysis is still in progress. Preliminary results demonstrate positive responses to individual treatment and environmental integration, whereas frequently changing contacts and the logistical effort were seen critically. Conclusions: Work is still in progress. We expect StäB to be an adequate alternative to inpatient treatment for women in puerperium and a new opportunity for patients who need intensive treatment but refuse hospitalisation. Introduction: Adverse childhood experiences (ACEs) are shown to be risk factors for developing anxiety later in life. However, one's family relationship acts as a protective factor between ACEs and anxiety. Objectives: The present study examines the interaction between ACEs and family relationship and their effect on generalized anxiety (GA) amongst the youth population in Hong Kong. Methods: Participants aged 15-24 were recruited from a populationbased epidemiological study in Hong Kong. GA in the past two weeks was assessed using GAD-7, while ACEs were measured using the childhood section of Composite International Diagnostic Interview screening scales (CIDI-SC), encompassing parental psychopathology, physical, emotional, sexual abuse, and neglect before age 17. Family relationship was measured by the Brief Family Relationship Scale (BFRS). Linear regression and a two-way ANCOVA were conducted to examine the association between ACEs, family relationship and GA, while adjusted for age and gender. Results: 633 (70.7%) out of 895 participants had any ACEs. ACEs significantly predicted GAD-7 scores (Β=1.272, t(891)=4.115, p<.001). Two-way ANCOVA reported a significant interaction effect of ACEs and family relationship on GA (F(1, 889)=4.398, p=.036), namely those who had any ACEs and poorer family relationship scored higher in GAD-7 (p<.001), whereas there was no difference in family relationship for those without ACEs on GA (p=.501). Conclusions: ACEs increases the vulnerability to GA later in life. However, its effect on anxiety decreases when one has a better family relationship. This suggests a possible moderating role of family relationship in developing GA among younger people.

Workplace violence in a 20 year follow-up study of norwegian physicians: The roles of gender, personality and stage of career Introduction: Workplace violence (WPV) is a worldwide health problem with major individual and societal consequences. Previously identified predictors of WPV include working in psychiatry and work stress.

Results
Conclusions: Higher rates of multiple threats and acts of violence were observed during early medical careers, with men at higher risk. Low levels of vulnerability traits (neuroticism) predicted independently the experience of violent threats. A cohort effect indicated a reduction in WPV (both threats and acts) in the younger cohort.
