Adolescent suicide is a major public health concern. Stressing the need for public health–based solutions, the Centers for Disease Control and Prevention identified “connectedness” as one means of pursuing this agenda. To advance this effort in suicide prevention with adolescents, (1) consistencies and variation in the literature overtly linking connectedness to suicide thoughts and behaviors (STB) are reviewed, (2) three more specific mechanistic pathways are proposed whereby connectedness may influence STB, and (3) several implications related to use of connectedness as a public health framework for adolescent suicide prevention and intervention are outlined. 相似文献

Associations between the satisfaction of basic psychological needs of autonomy, competence, and relatedness with current suicidal ideation and risk for suicidal behavior were examined. Two logistic regressions were conducted with a cross‐sectional database of 440 university students to examine the association of need satisfaction with suicidal ideation and risk for suicidal behavior, while controlling for demographics and depressive symptoms. Suicidal ideation was reported by 15% of participants and 18% were found to be at risk for suicidal behavior. A one standard deviation increase in need satisfaction reduced the odds of suicidal ideation by 53%, OR (95% CI) = 0.47 (0.33–0.67), and the odds of being at risk for suicidal behavior by 50%, OR (95% CI) = 0.50 (0.37–0.69). Young adults whose basic psychological needs are met may be less likely to consider suicide and engage in suicidal behavior. Prospective research is needed to confirm these associations. 相似文献

Epidemiologic studies have documented that injury survivors are at increased risk for suicide. We evaluated 206 trauma survivors to examine demographic, clinical, and injury characteristics associated with suicidal ideation during hospitalization and across 1 year. Results indicate that mental health functioning, depression symptoms, and history of mental health services were associated with suicidal ideation in the hospital; being a parent was a protective factor. Pre‐injury posttraumatic stress disorder symptoms, assaultive injury mechanism, injury‐related legal proceedings, and physical pain were significantly associated with suicidal ideation across 1 year. Readily identifiable risk factors early after traumatic injury may inform hospital‐based screening and intervention procedures. 相似文献

Adverse event (AE) detection and reporting practices were compared during the first phase of the Emergency Department Safety Assessment and Follow‐up Evaluation (ED‐SAFE), a suicide intervention study. Data were collected using a combination of chart reviews and structured telephone follow‐up assessments postenrollment. Beyond chart reviews, structured telephone follow‐up assessments identified 45% of the total AEs in our study. Notably, detection of suicide attempts significantly varied by approach with 53 (18%) detected by chart review, 173 (59%) by structured telephone follow‐up assessments, and 69 (23%) marked as duplicates. Findings provide support for utilizing multiple methods for more robust AE detection in suicide research. 相似文献

Suicide is a public health problem for African Americans who are young and of working age. The purpose of this study was to examine mediated and moderated effects of perceived racism on suicide ideation in a community sample of 236 African American men and women. Measures of suicide ideation, depression symptoms, intrinsic/extrinsic religiosity, and perceived racism were administered. Perceived racial discrimination was directly and indirectly associated with suicide ideation. For participants who reported low levels of extrinsic religiosity, the mediated effect of perceived racism (via depression symptoms) was significant. These findings provide some insight into suicide vulnerability for specific subgroups of African Americans. 相似文献

Chinese suicide rates have been reported in various studies in the past two decades, but few of them were based on national data. The most recent mortality data (2002–2011) provided by the China Ministry of Health and the detailed census data provided by the National Population Census were used in this study. We calculated the age‐, gender‐, and region‐specific suicide rates and their trends in the past 10 years between 2002 and 2011. The overall suicide rates in China decreased during the study period. The rural/urban ratio of the suicide rates has been significantly reduced from the ratio in the 1990s, and male suicide rates have exceeded those of females. Age was positively associated with suicide rates without the two peaks found in the suicide rates over 20 years ago. The Chinese suicide rates have significantly declined in the past decade, with withering of the unique suicide rate patterns previously found in Chinese suicides about 20 years ago. 相似文献

The differential relations between the emotion regulation strategies “cognitive reappraisal” and “expressive suppression” and suicidality in a mixed inpatient sample (N = 232, 69.4% female) of a German psychotherapeutic hospital were examined. Patients filled in the Emotion Regulation Questionnaire and items on suicidal ideation and desire. A structural equation model fitted the data (RMSEA = .044; CFI = .96) and revealed that “expressive suppression” significantly predicted increased suicidal ideation. Moderation analysis showed that results were independent from a current depressive episode. Potential implications for psychotherapeutic treatment of suicidality are discussed. 相似文献

Suicide determination is not standardized across medical examiners, and many suspected suicides are later classified as accidental or undetermined. The present study investigated patterns between these three groups using a medical examiner database and 633 structured interviews with next of kin. There were similarities across all three classification groups, including rates of mental illness and psychiatric symptoms. Those classified suicide were more likely to be male, to have died in a violent fashion, and have a stronger family history of suicide. Chronic pain was very common across all three groups, but significantly higher in the accidental and undetermined groups. 相似文献

Personality traits were examined using the NEO Five‐Factor Inventory–Revised in an Australian psychological autopsy study involving 259 suicide deaths and 181 sudden death controls aged 35 years and over. Interviews included the Structured Clinical Interview for DSM‐IV to determine the presence of psychiatric disorder. Personality traits of suicide deaths differed significantly from those of controls, scoring higher in the Neuroticism and Openness to Experience domains and lower on the Agreeableness and Extraversion domains. These findings varied with the presence of psychiatric disorder and by age. High Neuroticism scores were the most consistent finding in people who died by suicide, although these scores decreased in older suicides. 相似文献

Which factors distinguish suicide attempters from suicide ideators is a relatively neglected question in suicidology. Data from the 2001 Youth Risk Behavior Survey, encompassing 1,439 youth suicide ideators and 1,097 attempters, was used to explore which factors best differentiate suicide attempters from ideators, with a focus on violence involvement. Measures of violence include the contexts of fights, dating, and weapons carrying. Controls were incorporated for psychiatric disorders, risky sexual behavior, school integration, and demographics. Controlling for the other variables, violence differentiated attempts from ideation: fighting (OR = 2.18) and weapon carrying (OR = 1.13). Psychiatric factors that predicted attempts over ideation included major depression (OR = 1.86), use of cocaine (OR = 2.34), and having a suicide plan (OR = 2.69), while demographic factors included gender, age, residence in the Midwest, and Hispanic, African American, or Asian ethnicity. A supplementary analysis (N = 11,546) determined that violence also helped to differentiate suicide ideators from nonsuicidal youth. Four factors (including violence involvement, eating disorders, and gender consistently) differentiated both between suicide attempts and ideation, and also between suicide ideators and nonsuicidal youth. The link between violence involvement and suicidality is interpreted in terms of the capability for suicide from the interpersonal theory of suicide. 相似文献
