This study compared demographical and clinical variables between first and multiple suicide attempters and investigated risk and protective factors predicting multiple attempts. 228 patients visiting emergency department after attempting suicide were divided into two groups: first attempter (n=148, 64.9%) and multiple attempter (n=80, 35.1%). Demographic variables, clinical characteristics, factors related with suicide behavior, and psychiatric resources between two groups were compared. Multivariate logistic regression analysis was conducted to investigate risk and protective factors predicting multiple attempts. ⋯ Suicide ideation severity and conflicting interpersonal relationships predicted multiple suicide attempts, whereas past year's highest global functioning score and age over 45 protected against multiple suicide attempts. This study demonstrated that multiple suicide attempters have more severe clinical profile than first suicide attempters. Moreover, decreasing severity of suicide ideation, improving interpersonal relationships, and enhancing functioning level of suicide attempters might be important in preventing them from re-attempting suicide.

The impact of self-efficacy, alexithymia and multiple traumas on posttraumatic stress disorder and psychiatric co-morbidity following epileptic seizures: a moderated mediation analysis.
This study investigated the incidence of posttraumatic stress disorder (PTSD) and psychiatric co-morbidity following epileptic seizure, whether alexithymia mediated the relationship between self-efficacy and psychiatric outcomes, and whether the mediational effect was moderated by the severity of PTSD from other traumas. Seventy-one (M=31, F=40) people with a diagnosis of epilepsy recruited from support groups in the United Kingdom completed the Posttraumatic Stress Diagnostic Scale, the Hospital Anxiety and Depression Scale, the Toronto Alexithymia Scale-20 and the Generalized Self-Efficacy Scale. They were compared with 71 people (M=29, F=42) without epilepsy. ⋯ Moderated mediation also confirmed that self-efficacy and PTSD from one other trauma moderated the effect of alexithymia on outcomes. To conclude, people can develop posttraumatic stress disorder symptoms and psychiatric co-morbidity following epileptic seizure. These psychiatric outcomes are closely linked with their belief in personal competence to deal with stressful situations and regulate their own functioning, to process rather than defend against distressing emotions, and with the degree of PTSD from other traumas.

Blunted stress cortisol reactivity and failure to acclimate to familiar stress in depressed and sub-syndromal children.
Depressed adults have shown blunted or elevated cortisol reactivity in response to various forms of psychosocial stress. However, there have been few studies of cortisol reactivity in children who had early onset depression or a history of depression during the preschool-school period. The present study utilized a laboratory stress paradigm and collected salivary cortisol from preschoolers at baseline (ages 3-5 years) and 24-month follow-up (ages 5-7 years). ⋯ In contrast, children with MDD (n=46) and sub-syndromal MDD (n=76) showed a peak cortisol response to the novelty of lab arrival and then reduced and blunted responses to stressors at baseline. These cortisol responses persisted at follow-up in children with a history of MDD (n=41) or sub-syndromal MDD (n=73). These results suggest that the hypothalamic-pituitary-adrenal (HPA) axis shows a blunted response to stress and failed to acclimate to familiar stressful situations in depressed and sub-syndromal depressed children.

Comparative StudyFrequency and risk factors of workplace violence on psychiatric nurses and its impact on their quality of life in China.
This study examined the frequency of violence on nurses in Chinese psychiatric hospitals and explored its risk factors and impact on nurses' quality of life (QOL). A survey was conducted with 387 frontline psychiatric nurses in China. Information about experience of workplace violence in the past 6 months, type of workplace violence, and demographic characteristics was collected by a questionnaire. ⋯ Significant predictors of violence against nurses are male sex, receiving college level or higher education and working on rotating duty were independently associated with high risk of violence. Workplace violence against psychiatric nurses commonly occurs in China. Considering the deleterious effects of violence, comprehensive strategies from the perspective of nursing education and training, organizational policy, patient care and staff support are recommended to promote occupational safety in psychiatric settings in China.

Validity of the Patient Health Questionnaire-9 for depression screening and diagnosis in East Africa.
Depression is often underdiagnosed and undertreated in primary care settings, particularly in developing countries. This is, in part, due to challenges resulting from lack of skilled mental health workers, stigma associated with mental illness, and lack of cross-culturally validated screening instruments. We conducted this study to evaluate the reliability and validity of the Patient Health Questionnaire-9 (PHQ-9) as a screen for diagnosing major depressive disorder among adults in Ethiopia, the second most populous country in sub-Saharan Africa. ⋯ A factor analysis confirmed a one-factor structure. Receiver Operating Characteristics (ROC) analysis showed that a PHQ-9 threshold score of 10 offered optimal discriminatory power with respect to diagnosis of major depressive disorder via the clinical interview (sensitivity=86% and specificity=67%). The PHQ-9 appears to be a reliable and valid instrument that may be used to diagnose major depressive disorders among Ethiopian adults.
