生活事件与大学生自杀意念的关系——气质性乐观的调节作用

目的在医学生中探讨气质性乐观、生活事件与自杀意念的关系。方法采用自杀意念自评量表以及乐观问卷、青少年生活事件量表对两所医学院校的800名临床医学专业学生进行调查。结果①应激事件对医学生的自杀意念水平有正向预测作用,应激事件越严重,学生的自杀意念水平越高;②气质性乐观对应激事件与自杀意念之间的关系具有调节作用。结论气质性乐观是负性生活事件与自杀意念之间的调节器。     

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。     

师范生职业认同与自杀意念的关系:抑郁的中介作用及其性别差异

基于心理健康的社会学模型和社会-文化模型,本研究考察师范生职业认同与自杀意念之间的关系,以及性别的调节效应和抑郁的中介效应。被试为700名师范生,研究工具包括师范生职业认同感量表、自杀意念自评量表、流调中心用抑郁自评量表。结果表明：（1）职业认同得分、自杀意念检出率的性别差异显著;（2）职业认同与抑郁、自杀意念均呈显著的负相关,自杀意念和抑郁呈显著的正相关;（3）性别在职业认同负向预测自杀意念的关系中起到调节作用,该调节作用还部分通过抑郁这一中介变量来实现。     

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。     

大学生抗挫折心理能力对自杀意念影响的研究

为了探讨大学生抗挫折心理能力对自杀意念的影响,采用《抗挫折心理能力问卷》和《自杀意念自评量表》对882名大学生进行调查研究.结果发现:(1)大学生抗挫折心理能力在性别、年级、生源、学校类型等因素上存在显著差异;(2)大学生抗挫折心理能力与自杀意念之间呈显著的负相关,抗挫折心理能力的多个因素与自杀意念各因素之间的负相关显著;(3)大学生的挫折容忍力、意志品质、挫折复原力、信心、挫折认知水平、挫折经验是自杀意念的有效预测变量.     

老年人年龄认同特征及其与心理健康的关系

采用年龄认同问卷、流调中心用抑郁量表、焦虑自评量表和生活满意度量表对646位老年人进行问卷调查,考察我国老年人年龄认同的特征及其与心理健康之间的关系。结果表明:(1)老年人感觉自己比实际年龄年轻的人数比例为55.7%,平均年轻4.07年。实际年龄和自评健康对老年人的年龄认同有显著影响。(2)回归分析结果表明,在控制了性别、受教育水平、自评健康等变量后,年龄认同仍然对老年人的心理健康有显著影响,表现在对其焦虑和抑郁情绪有显著的负向预测作用,对其生活满意度水平有显著的正向预测作用。综上,我国老年人年龄认同存在年轻化偏向,而且这种年轻化偏向程度越强,老年人的焦虑和抑郁情绪越少,生活满意度水平越高。这意味着可以采取适当干预措施促使老年人保持年轻化的年龄认同,这可能将有助于改善老年人的心理健康状况。     

高中生自杀意念的保护性因素:积极心理(乐观)的中介作用

目的:了解高中生的绝望感、自杀意念状况,分析中学生自杀意念的保护性因素的作用机制,为自杀的心理干预提供必要的支持。方法:采用分层整群抽样法抽取在校高中生300人,利用应对效能量表、贝克绝望量表和自杀意念量表等进行调查分析。结果:自杀意念者的检出率为15%,数量分布无性别、年级和独生子女上的差异;应对效能、家庭亲密度和适应性和乐观主义与自杀意念呈显著负相关,对自杀意念有显著的负向影响;乐观主义在应对效能、家庭亲密度和适应性对自杀意念的影响种起部分中介作用。结论:应对效能、家庭亲密度和适应性和乐观主义是自杀意念的重要保护性因素;应对效能、家庭亲密度和适应性通过乐观主义对自杀意念产生影响。     

困境儿童孤独与社交焦虑对抑郁的影响——自尊的中介作用

为探讨困境儿童孤独、社交焦虑、抑郁和自尊的现状、特点、关系以及自尊在其中的中介作用,进而为困境儿童心理帮扶及救助提供依据。本研究使用儿童抑郁障碍自评量表、儿童孤独量表、儿童社交焦虑量表和自尊量表对重庆市17个区县1733名困境儿童进行调查。结果发现:(1)抑郁、社交焦虑和自尊存在性别差异,抑郁、孤独、社交焦虑和自尊存在年龄差异;(2)孤独和社交焦虑与抑郁呈显著正相关并显著预测抑郁,自尊与抑郁呈显著负相关并显著预测抑郁。(3)困境儿童的自尊在孤独和抑郁之间,社交焦虑和抑郁之间起中介作用。结果表明:困境儿童的孤独、社交焦虑既可直接影响其抑郁水平,也可通过自尊的中介作用间接影响其抑郁水平。     

神经质对青少年情绪化饮食的影响：一个有调节的中介效应模型

摘 要 为探讨神经质、青少年情绪化饮食、体验回避及自尊之间的关系,选取1000名青少年为被试,采用简式大五人格问卷、荷兰饮食行为问卷、接纳行动量表及自尊量表进行测试。结果表明：（1）神经质对青少年情绪化饮食有显著的正向影响,并间接地通过体验回避对青少年情绪化饮食产生作用;（2）自尊在体验回避对青少年情绪化饮食的影响中起显著的调节作用,具体而言,在低自尊水平下,体验回避能显著地正向预测青少年情绪化饮食,而在高自尊水平下,体验回避对青少年情绪化饮食的预测作用不显著。     

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。     

Self-critical perfectionism and depressive symptoms: Low self-esteem and experiential avoidance as mediators

This study of community adults (N = 210) aimed to gain a better understanding of the links among self-critical (SC) perfectionism, self-esteem, experiential avoidance, and depressive symptoms. Participants completed self-report questionnaires assessing perfectionism dimensions, self-esteem, experiential avoidance, and depressive symptoms. Confirmatory factor analysis supported SC perfectionism, self-esteem, experiential avoidance, and depressive symptoms as distinct, but related, constructs. Structural equation modeling (SEM) demonstrated that the relation between SC perfectionism and depressive symptoms was mediated by lower self-esteem. SEM also showed that experiential avoidance independently mediated the relation between SC perfectionism and depressive symptoms, controlling for the effects of lower self-esteem. These results distinguish SC perfectionism from lower self-esteem by demonstrating that individuals with higher SC perfectionism have a unique propensity toward experiential avoidance, which, in turn, incrementally explains why they experience higher levels of depressive symptoms.     

Depressive thinking and depression: relations with personality and social resources

The mechanisms by which social supports and personality variables may buffer against psychopathology are not well understood. We studied depression, depressive cognitions, social supports, and self-esteem in a sample of 68 spouse-caregivers of patients with Alzheimer's Disease in an attempt to identify possible buffering mechanisms of the latter two variables. Specifically, we hypothesized that the well-known relation of depressive cognitions to depression would vary as a function of satisfaction with social supports and with level of self-esteem. Hierarchical multiple regression analyses conducted to predict depression revealed significant and independent main effects for depressive cognitions (p less than .01), social supports (p less than .025), and self-esteem (p less than .001), with depressive cognitions associated with higher depression and the other two variables associated with reduced depression (R2 = .53 for the three main effects). In addition, the relation of depressive cognitions with depression varied substantially depending on the level of social supports (p less than .01); caregivers with high levels of depressive cognitions had high levels of depression only if social supports were low (R2 = .61 including interaction). Self-esteem and depressive cognitions showed a similar interaction, but it failed to reach significance. Analyses to determine whether self-esteem and social supports were directly associated with lower depressive cognitive activity yielded a main effect for self-esteem only (p less than .03). Thus, whereas social supports and self-esteem were directly associated with lower depression, only the social supports variable was further associated with reduced depression because it apparently buffered the impact of depressive thinking. Self-esteem was also indirectly associated with lower depression via its relation with lower depressive thinking. Implications of our results for cognitive theories of depression and for the psychosocial mechanisms of stress buffering are discussed.     

An experiential avoidance conceptualization of depressive rumination: Three tests of the model

This study examined an experiential avoidance conceptualization of depressive rumination in 3 ways: 1) associations among questionnaire measures of rumination, experiential avoidance, and fear of emotions; 2) performance on a dichotic listening task that highlights preferences for non-depressive material; and 3) psychophysiological reactivity in an avoidance paradigm modeled after the one used by Borkovec, Lyonfields, Wiser, and Deihl (1993) in their examination of worry. One hundred and thirty-eight undergraduates completed questionnaire measures and participated in a clinical interview to diagnose current and past episodes of depression. Of those, 100 were randomly assigned to a rumination or relaxation induction condition and participated in a dichotic listening task, rumination/relaxation induction, and depression induction. Questionnaire measures confirmed a relationship between rumination status and avoidance; however, no significant effects were found in the dichotic listening task. Psychophysiological measures indicated no difference in physiological response to a depression induction among high ruminators (HR). However, low ruminators (LR) in the relaxation condition exhibited a larger IBI response than LR in the rumination condition. Overall, these results provide partial support for an avoidance conceptualization of depressive rumination. Implications of these findings are discussed.     

The relationship between rumination, avoidance and depression in a non-clinical sample

Recent commentaries have proposed conceptualizations of rumination in terms of both cognitive and behavioral avoidance. This study examined the relationship between rumination, avoidance and depression using a newly developed self-report measure of avoidance in depression, the Cognitive-Behavioral Avoidance Scale (CBAS) [Ottenbreit, N.D., & Dobson, K.S. (2004). Avoidance and depression: The construction of the cognitive-behavioral avoidance scale. Behaviour Research and Therapy, 42, 293-313]. A non-clinical sample (N=104) of undergraduate students completed self-report measures of depression, anxiety, rumination and avoidance. Rumination, avoidance and depression were all significantly correlated. Rumination and behavioral avoidance remained intercorrelated when anxiety was controlled, confirming an association that is independent of anxiety. By contrast, the relationship between cognitive avoidance and rumination disappeared when anxiety was partialled out. Notably, avoidance predicted unique variance in depression scores, over and above anxiety and rumination. Consistent with the proposal of Ottenbreit and Dobson [Avoidance and depression: The construction of the cognitive-behavioral avoidance scale. Behaviour Research and Therapy, 42, 293-313], our findings support the value of clinicians and psychopathologists giving consideration to avoidance in their conceptualization of depression.     

Brooding and reflective rumination among suicide attempters: Cognitive vulnerability to suicidal ideation

Previous research suggests that the brooding subtype of rumination is associated with increased suicidal ideation, but findings are inconsistent with respect to reflection, considered to be the more adaptive form of rumination. This study investigated the circumstances under which reflective rumination might be associated with increased suicidal ideation by examining whether a suicide attempt history moderated the relationship between the ruminative subtypes and current suicidal ideation. Thirty-seven young adults who reported a past suicide attempt and fifty-nine young adults without a suicide attempt history completed measures of rumination and depression symptoms in an initial study session. They then completed a measure of suicidal ideation and hopelessness during a second study session. Overall, brooding was associated with higher self-reported suicidal ideation, whereas reflection was not significantly associated with ideation. However, reflection - but not brooding - interacted with suicide attempt history to statistically predict suicidal ideation, even after adjusting for symptoms of depression and hopelessness, whereas brooding no longer predicted ideation after adjusting for these symptoms. These findings qualify earlier suggestions that reflection is a more adaptive form of rumination by indicating that among vulnerable individuals - in particular those with a history of a suicide attempt - a higher degree of reflective rumination is associated with increased suicidal ideation.     

Child sexual abuse coping and long term psychological adjustment

The aim of the study was to analyze the consequences of Child Sexual Abuse (CSA) on the psychological adjustment of university students, as well as the way in which several avoidance and approach coping strategies affect that adjustment. The sample comprised 1162 students from the University of Granada. Data about CSA was obtained from a questionnaire developed with this aim. We used the How I Deal with Things Scale of Burt and Katz to evaluate coping strategies, whereas depression and self-esteem were assessed with the Beck Depression Inventory and the Rosenberg Self-Esteem Scale, respectively. Subjects who were victims of CSA showed significantly higher scores on depression and lower scores on self-esteem. An analysis of coping strategies revealed that only the use of avoidance strategies was related to psychological adjustment. Subjects who used these strategies obtained higher scores on depression and lower scores on self-esteem. These results confirm the idea of CSA as a risk experience that can affect victims' psychological adjustment, to a greater or lesser extent, according to the coping strategy employed.     

Initial psychometric properties of the experiences questionnaire: validation of a self-report measure of decentering

Decentering is defined as the ability to observe one's thoughts and feelings as temporary, objective events in the mind, as opposed to reflections of the self that are necessarily true. The Experiences Questionnaire (EQ) was designed to measure both decentering and rumination but has not been empirically validated. The current study investigated the factor structure of the EQ in both undergraduate and clinical populations. A single, unifactorial decentering construct emerged using 2 undergraduate samples. The convergent and discriminant validity of this decentering factor was demonstrated in negative relationships with measures of depression symptoms, depressive rumination, experiential avoidance, and emotion regulation. Finally, the factor structure of the EQ was replicated in a clinical sample of individuals in remission from depression, and the decentering factor evidenced a negative relationship to concurrent levels of depression symptoms. Findings from this series of studies offer initial support for the EQ as a measure of decentering.     

自我隐瞒对消防员创伤后应激反应的影响：经验回避和反刍的链式多重中介作用

人格特质和情绪调节策略是创伤后应激反应的重要影响因素。作为一种在个人感到痛苦时有意地向他人隐藏自身状况的人格特质,自我隐瞒会通过适应不良的情绪调节策略影响心理健康。然而,鲜有研究考察自我隐瞒、适应不良的情绪调节策略与创伤后应激反应的关系。对创伤后应激反应的情绪调节策略的研究发现,经验回避和反刍是两种有重要影响的适应不良的情绪调节策略。在创伤后应激反应的研究对象上,前人主要关注在创伤事件中幸存的直接受害者身上,而对频繁处理各类突发事件而成为创伤后应激反应高危人群的消防员一直缺乏研究。因此,本研究意在考察自我隐瞒对经历职业创伤的消防员创伤后应激反应的影响以及经验回避和反刍这两种适应不良的情绪调节策略的中介作用。 研究被试为215名将个人经历的职业创伤作为首要创伤事件的一线消防员。他们来自我国3个城市,均为男性,平均年龄22.90±3.38岁。使用中文修订版的埃森创伤问卷、自我隐瞒量表、反刍反应量表、接受与承诺问卷第二版和事件影响量表进行现场调查。被试均匿名填写调查问卷。使用SPSS20.0进行描述性统计和相关性分析。使用Mplus7.4进行结构方程模型的分析。采用Harman单因子检验的方法进行共同方法偏差检验。采用偏差矫正的百分位Bootstrap方法进行中介效应的显著性检验。 结果表明,自我隐瞒、经验回避、反刍和创伤后应激反应之间存在两两显著正相关;自我隐瞒对创伤后应激反应具有直接效应;自我隐瞒通过反刍对创伤后应激反应产生间接效应;自我隐瞒通过经验回避-反刍的中介链对创伤后应激反应产生间接效应;自我隐瞒影响创伤后应激反应的总效应值为0.427,其中总间接效应值为0.217,占总效应值的50.82%。本研究还发现,64名(29.77%)将个人经历的职业创伤作为首要创伤事件的一线消防员达到了严重创伤后应激反应的水平。 总之,自我隐瞒可以通过三条路径影响创伤后应激反应：直接影响、反刍的中介作用和经验回避-反刍的系列中介作用。在理论层面,这拓展了对影响创伤后应激反应的人格特质的理解和对自我隐瞒影响的心理健康状况的理解。在实践层面,这提示我们重视自我隐瞒、经验回避和反刍在预防和治疗创伤后应激反应中的潜在贡献。此外,本研究还发现,消防员确实是创伤后应激反应的高危人群。作为突发事件的第一响应人,消防员的心理健康应该得到更多关注与研究。     

生活事件对初中生抑郁的影响:自尊和反刍思维的链式中介作用

为了探讨生活事件、自尊、反刍思维和初中生抑郁之间的关系,研究采用青少年生活事件量表、自尊量表、反刍思维量表和儿童抑郁量表对684名初中生进行调查。结果显示：（1）生活事件与初中生抑郁呈显著正相关;（2）自尊和反刍思维在生活事件和初中生抑郁间起链式中介作用。生活事件不仅是触发初中生抑郁的重要外部因素,而且生活事件还会通过影响自尊和经由反刍思维对初中生抑郁产生间接作用。因此,减少和避免生活事件对初中生心理的冲击,增强其自尊水平,调整其负性认知方式是改善和预防初中生抑郁的重要途径。
