Nurses experience a high incidence of workplace bullying and are at a higher risk of suicide than the general population. However, there is no empirical evidence on how exposure to workplace bullying is associated with suicide ideation and attempts among nurses. Nurses were recruited from tertiary hospitals in Shandong Province, China, using stratified cluster sampling. Suicide ideation and attempts were assessed using two items, and the Workplace Psychologically Violent Behaviors Instrument was used to measure subtypes of workplace bullying. The prevalence of workplace bullying, suicide ideation, and suicide attempts was 30.6%, 16.8%, and 10.8%, respectively. After adjusting for covariates, victims of workplace bullying were at a high risk of suicide ideation and attempts. Among workplace bullying subtypes, individuals’ isolation from work and direct negative behaviors were predictors of both suicide ideation and attempts; attack on personality only predicted suicide attempts. The more bullying subtypes experienced by nurses, the greater their likelihood of suicide ideation and attempts. These findings suggested that workplace bullying was associated with an increased risk of suicide ideation and attempts in nurses, with both independent and cumulative risks. Interventions should focus on prevention and managing the effects of workplace bullying among nurses.

BackgroundWomen undergoing in vitro fertilization-embryo transfer (IVF-ET) treatment were generally found to experience varying degrees of psychological distress across the treatment. Existing studies focused on total scores and diagnostic thresholds to characterize the symptoms’ severity, which might hinder scientific progress in understanding and treating psychological distress.AimsWe aimed to investigate (a) how depression and anxiety symptoms are interconnected within a network, and (b) the changes of the network (symptom connections and network centralities) over time, in women undergoing in vitro fertilization-embryo transfer.MethodsA 4-wave longitudinal study was designed with 343 eligible women recruited from the Reproductive Medicine Center of a tertiary hospital in China. The network models were created to explore the relationship and changes between psychopathology symptoms both within and across anxiety and depression, with anxiety measured by the Generalized Anxiety Disorder-7 and depression measured by the Patient Health Questionnaire-9. Symptom network analysis was conducted to evaluate network and network properties, network centrality, and bridge centrality, as well as change trajectory network.ResultsFor the strength centrality, “inability to control worry” and “worrying too much” were the most central symptoms at T1; however, these symptoms decreased. The centrality of “sadness” and “guilt” tended to increase steadily and became dominant symptoms. For bridge centrality indices, several bridge symptoms were identified separately from T1 to T4: “irritability,” “concentration difficulties,” “nervousness,” and “restlessness;” “guilt” exhibited increased bridge symptoms. Furthermore, the change trajectory network indicated that “suicide ideation” became more closely related to guilt but not to worrying too much over time.ConclusionThis study provides novel insights into the changes in central features, connections, and bridge symptoms during IVF-ET treatment and identified several bridge symptoms separately at different stages, which could activate the connection between psychopathology symptoms. The results revealed that sense of guilt was associated with worsening psychopathology symptoms, indicating that future psychological interventions should target guilt-related symptoms as a priority.

Infant neglect is a common type of child maltreatment. According to the Social Information Processing theory, maternal executive function (EF) and reflective function (RF) are assumed to be important contributing factors to infant neglect. However, empirical evidence about this assumption is sparse. This was a cross-sectional study. A total of 1010 eligible women participated. The Behavior Rating Inventory of Executive Function—Adult Version, Parental Reflective Function Questionnaire, and Signs of Neglect in Infants Assessment Scale (SIGN) were used to assess maternal EF, RF, and infant neglect, respectively. Random forest was used to assess the relevant importance of maternal EF and RF. K-means clustering was used to identify the profiles of maternal EF and RF. Multivariable linear regression and generalized additive models were used to examine the independent and combined effects of maternal EF and RF on infant neglect. Each dimension of EF was linearly related to infant neglect. The associations between each dimension of RF and infant neglect were nonlinear. The inflection point for each dimension of RF was indicated. Random forest showed EF was more closely related to infant neglect. EF and RF had accumulative effects on infant neglect. Three profiles were identified. Among them, those with globally impaired EF had the highest level of infant neglect compared with those who had normal cognition or only impaired RF. Maternal EF and RF had independent and combined effects on infant neglect. Interventions with maternal EF and RF as targets are promising for reducing infant neglect.
