校园氛围与青少年的自杀意念/企图：自尊的中介作用

尽管相当一部分青少年自杀发生于学校背景中,但目前较少有研究考察校园氛围是否会影响以及怎样影响青少年的自杀意念/企图。本研究旨在检验校园氛围的不同方面(教师支持、同学支持、自主机会)与青少年自杀意念/企图的关系,以及自尊在其中的中介作用。采用分层整群抽样的方法,选取广东省10所学校2758名初中生作为被试,匿名填写家庭功能问卷、社区问题问卷、校园氛围问卷、Rosenberg自尊量表、自杀意念与企图问卷。回归分析表明:(1)在控制了性别、年龄、社会经济地位、家庭功能和社区问题后,教师支持和同学支持均能显著负向预测自杀意念/企图,自主机会对自杀意念/企图的预测作用不显著;(2)自尊在教师支持和同学支持与自杀意念/企图之间起着中介作用。因此,实践工作中应重视教师支持和同学支持对青少年自尊的塑造作用,进而减少自杀意念/企图。     

创伤后应激障碍对震后青少年自杀意念的影响：安全感的调节作用

为探讨创伤后应激障碍（PTSD）及其各个症状簇对震后青少年自杀意念的影响,并检验安全感在其中的调节作用,研究采用创伤暴露程度问卷、流调中心抑郁量表儿童版、DSM-5的PTSD症状核查表、安全感量表和儿童行为问题核查表对汶川地震8.5年后的1136名中学生进行调查。结果发现：PTSD、负性认知和情绪改变症状、警觉性增高症状分别正向预测自杀意念,侵入性症状和回避性症状对自杀意念的预测作用不显著;安全感在侵入性症状、负性认知和情绪改变症状、警觉性增高症状、PTSD与自杀意念之间起负向调节作用,在回避性症状与自杀意念之间不起调节作用。这表明PTSD各症状簇对震后青少年自杀意念的预测作用不同,且安全感在其中发挥的调节作用也不同。     

高中生自杀意念的素质-应激模型：多时段追踪研究

目的：探讨神经质人格和负性生活事件的跨层相互作用对自杀意念的影响。方法：采用自杀意念问卷、青少年生活事件问卷和大五人格量表-神经质分量表等自评量表对618名高中生进行评估,每三个月追踪1次,共追踪7次,历时21个月,用多层线性模型分析数据。结果：在控制了第一次自杀意念和性别的影响后,负性生活事件的主效应（b = 0.08, F(1, 2963) = 37.93, p < 0.001）、负性生活事件与神经质人格的相互作用（b = 0.03, F(1, 2963) = 4.35, p < 0.001）显著,而神经质人格的主效应不显著（b = 0.59, F(1, 557)= 3.05, p > 0.05）。结论：神经质人格和负性生活事件的跨层相互作用可以预测自杀意念的变化,支持素质-应激模型。     

儿童心理虐待与忽视和自杀意念的关系：有调节的中介模型

采用问卷法对988名初中生进行调查,探究儿童心理虐待与忽视和自杀意念的关系,应对方式的中介作用以及友谊质量的调节作用。结果表明：（1）儿童心理虐待与忽视正向预测自杀意念;（2）应对方式是儿童心理虐待与忽视和自杀意念之间的中介变量;（3）儿童心理虐待与忽视对自杀意念的直接效应受到友谊质量的调节,直接效应对于友谊质量低的青少年更显著;（4）儿童心理虐待与忽视通过应对方式对自杀意念的间接效应的后半段受到友谊质量的调节,友谊质量高的青少年的自杀意念水平相对更低。因此,儿童心理虐待与忽视和自杀意念之间是有调节的中介关系,儿童心理虐待与忽视通过应对方式影响自杀意念,友谊质量在直接路径和间接路径中起调节作用。     

青少年网络被欺负与自杀意念的关系:自尊和情绪应对方式的链式中介作用

为探讨青少年网络被欺负、自尊、情绪应对方式和自杀意念的关系,采用网络被欺负量表、自尊量表、中学生应对方式量表和自杀意念量表对来自湖北、河南、安徽三省六所高中的802名高一学生进行调查,结果发现：网络被欺负直接影响自杀意念,且存在三条间接路径：通过自尊的单独中介作用影响自杀意念;通过情绪应对方式的单独中介作用影响自杀意念;通过自尊和情绪应对方式的链式中介作用影响自杀意念。研究有助于了解青少年网络被欺负对自杀意念的影响机制,对预防以及减少青少年自杀行为具有一定的现实意义。     

冲动性特质对高中生自杀意念的影响:校园排斥与生命意义感的作用

采用冲动性特质量表、青少年遭受校园排斥问卷、生命意义感量表、自杀意念量表对633名高中生进行调查。结果表明:(1)冲动性特质对高中生自杀意念有显著的正向预测作用;(2)校园排斥在冲动性特质与高中生自杀意念间起部分中介作用;(3)冲动性特质经由校园排斥影响高中生自杀意念的中介作用受生命意义感的调节,随着生命意义感的增加,校园排斥对自杀意念的效应逐步减弱。冲动性特质可以通过校园排斥增加高中生自杀意念强度,而生命意义感能有效降低校园排斥对自杀意念的消极影响。     

父母忽视对青少年自杀意念的影响:自尊和希望的中介作用

为考察父母忽视对青少年自杀意念的影响及其作用机制,采用父母忽视量表、自尊量表、希望量表和自杀意念量表,对全国七个省份八所中学共845名初二学生进行调查。结果表明：（1）父母忽视、自尊、希望和自杀意念两两之间存在显著的相关,且父母忽视对自杀意念具有显著的正向预测作用;（2）自尊和希望在父母忽视与自杀意念的关系中起部分中介作用。具体而言,父母忽视通过三条路径影响自杀意念：一是自尊的单独中介作用;二是希望的单独中介作用;三是自尊-希望的链式中介作用。本研究揭示了父母忽视与青少年自杀意念的关系及其作用机制,对预防以及减少青少年自杀行为具有一定的现实意义。

Suicidal Ideation of Psychiatrically Hospitalized Adolescents has One-Year Predictive Validity for Suicide Attempts in Girls Only

Clinicians commonly incorporate adolescents’ self-reported suicidal ideation into formulations regarding adolescents’ risk for suicide. Data are limited, however, regarding the extent to which adolescent boys’ and girls’ reports of suicidal ideation have clinically significant predictive validity in terms of subsequent suicidal behavior. This study examined psychiatrically hospitalized adolescent boys’ and girls’ self-reported suicidal ideation as a predictor of suicide attempts during the first year following hospitalization. A total of 354 adolescents (97 boys; 257 girls; ages 13–17 years) hospitalized for acute suicide risk were evaluated at the time of hospitalization as well as 3, 6, and 12 months later. Study measures included the Suicidal Ideation Questionnaire-Junior, Multidimensional Anxiety Scale for Children, Children’s Depression Rating Scale-Revised, Beck Hopelessness Scale, Youth Self-Report, and Personal Experiences Screen Questionnaire. The main study outcome was presence and number of suicide attempt(s) in the year after hospitalization, measured by the Diagnostic Interview Schedule for Children. Results indicated a significant interaction between suicidal ideation, assessed during first week of hospitalization, and gender for the prediction of subsequent suicide attempts. Suicidal ideation was a significant predictor of subsequent suicide attempts for girls, but not boys. Baseline history of multiple suicide attempts was a significant predictor of subsequent suicide attempts across genders. Results support the importance of empirically validating suicide risk assessment strategies separately for adolescent boys and girls. Among adolescent boys who have been hospitalized due to acute suicide risk, low levels of self-reported suicidal ideation may not be indicative of low risk for suicidal behavior following hospitalization.     

Correlates of suicidal ideation among rural adolescents

This study examined potential predictors of suicidal ideation among a nonclinical, rural adolescent population. A sample of 76 male and female adolescents enrolled in a rural public high school completed a personal information form, a suicide information questionnaire, short forms of the Beck Depression Inventory and the Family Environment Scale, and the Life Events Checklist. A stepwise multiple regression suggested significant predictive relationships between magnitude of suicidal ideation and measures of family social climate (i.e., Organization, Conflict, Expressiveness, and Independence subscales from the Family Environment Scale--Short Form). Multivariate analyses of variance and a discriminant-function analysis revealed no significant sex differences.     

Parenting and Chinese Adolescent Suicidal Ideation and Suicide Attempts: The Mediating Role of Hopelessness

Various family factors are risk factors for adolescent suicidality (suicidal ideation and suicide attempts). However, little is known about the role of parenting in adolescent suicidality. The present study examined the unique relations between three parenting dimensions (parental warmth, behavioral control, and psychological control) and adolescent suicidality, as well as the mediating role of adolescent hopelessness among these relations. A total of 1529 Chinese adolescents (52 % male; mean age = 14.74 years, SD = 1.48) completed anonymous questionnaires designed to assess three parenting dimensions, hopelessness, suicidal ideation and suicide attempts. After controlling for gender, age, family structure, and socioeconomic status, it was found that parental warmth negatively predicted adolescent suicidality, whereas psychological control positively predicted adolescent suicidality. In addition, parental warmth negatively predicted adolescent hopelessness, whereas psychological control positively predicated adolescent hopelessness, which in turn enhanced adolescent suicidality. Although behavioral control did not predict adolescent suicidality, it did negatively predict adolescent hopelessness, which in turn promoted adolescent suicidality. These findings revealed the differential roles of different parenting dimensions in adolescent suicidality, and the mediation effect of adolescent hopelessness between parenting and adolescent suicidality. Future practices would benefit from incorporating both parenting and hopelessness for optimal intervention effect.     

Forgiveness,Depression, and Suicidal Behavior in Adolescents: Gender Differences in this Relationship

With the development of positive psychology, protective factors have received increased attention as buffers against suicidal ideation and attempts and against the risk factors for suicide (e.g., depressive symptoms). Empirical evidence suggests that one of the protective factors associated with depression and suicide is forgiveness. Although previous studies have demonstrated a negative association between forgiveness and risk of suicide, studies on gender differences in adolescents are still scarce. Thus, the authors assessed the moderating role of gender in a sample of adolescents. The participants were 572 adolescents (50.9% boys; M age = 15.49 years, SD = 1.09 years) from secondary school centers. The results revealed that forgiveness moderated the relationship between depression and suicidal ideation for boys but not for girls. Specifically, for boys the relationship between depression and suicidal thoughts and behaviors weakened as levels of forgiveness increased. These findings suggest therapeutic applications to reduce the likelihood of suicide in the group of adolescent boys with higher scores on depression and lower levels of forgiveness. The study results are discussed in terms of the need to use gender perspectives in positive psychology intervention programs.     

Coping,Reasons for Living,and Suicide in Black College Students

The authors examined the roles of reasons for living and coping in protecting against suicidal behaviors among 361 Black college students. Results of a path analysis revealed that reasons for living mediated against suicidal ideation through an inverse effect on depression. Results also indicated that greater use of emotion‐oriented coping may lead to suicidal ideation through increased depression and decreased reasons for living, whereas avoidance‐oriented coping protected against suicide. Implications for these results are further discussed.     

Trajectories of Suicidal Ideation from Sixth through Tenth Grades in Predicting Suicide Attempts in Young Adulthood in an Urban African American Cohort

The trajectory of suicidal ideation across early adolescence may inform the timing of suicide prevention program implementation. This study aimed to identify developmental trajectories of suicidal ideation among an urban cohort of community‐residing African Americans (AA) longitudinally followed from middle school through early adulthood (ages 11–19 years). Subtypes based on the developmental course of suicidal ideation from late childhood through mid‐adolescence were identified using longitudinal latent class analysis (LLCA) with 581 AA adolescents (52.7% male; 71.1% free or reduced school meals). The developmental trajectories of suicidal ideation were then used to predict suicide attempts in young adulthood. Our LLCA indicated two subtypes (i.e., ideators and nonideators), with 8% of the sample in the ideator class. This trajectory class shows a peak of suicidal ideation in seventh grade and a steady decline in ideation in subsequent grades. Additionally, suicidal ideation trajectories significantly predicted suicide attempt. Results of these analyses suggest the need for suicide prevention approaches prior to high school for AA youth.     

The Moderating Effects of Gratitude on the Association Between Perceived Parenting Styles and Suicidal Ideation

Suicidal ideation is defined as the thoughts about engaging in suicidal-related behaviors. Very few studies have been conducted on children’s suicidal ideation as there is a biased perception that suicidal behavior under the age of 12 is scarce. However, suicide is the leading cause of death among young children. Child suicidal ideation is predictive of suicidal ideation and suicide attempts in adulthood. Association between certain parenting styles and suicidal ideation have been found in empirical studies. However, little is known about the role of parenting and suicidal ideation in Chinese young children. We examined whether gratitude can reduce the risk of suicide by moderating the association between parenting styles and child suicidal ideation. We recruited 447 Chinese children (53.3% female; mean age?=?10.06, SD?=?1.76) to participate in a survey. Perceived parenting style (warmth/accepting, dominating, and autonomy granting), gratitude, and suicidal ideation were assessed using self-reported measures. We found that all three perceived parental styles were significantly associated with child suicidal ideation. Further, gratitude was found to have a significant moderating effect on suicidal ideation, across the analysis of the three perceived parenting styles. This suggests that gratitude may be adopted in preventive and clinical interventions so that children at risk can benefit from reducing the negative effects of ineffective parenting styles and suicidal ideation.
