失独父母创伤后应激障碍症状的潜在类别及其相关因素

摘 要 研究旨在探讨失独父母创伤后应激障碍（PTSD）症状的潜在类别及相关因素,分析不同类别失独父母心理韧性的差异。采用创伤后应激障碍量表（PCL-5）、心理韧性量表对385名失独父母进行测查。结果发现：（1）失独父母PTSD症状存在三种潜在类别：PTSD高症状组（30%）、PTSD中度症状组（38%）、PTSD低症状组（32%）。（2）相比PTSD低症状组而言,PTSD高或中度症状组有显著的年龄和失独年限效应,PTSD高症状组中年龄≤60岁、失独年限<10年的人群所占比例较高;PTSD中度症状组的年龄≤60岁的人群所占比例更高。（3）PTSD高症状组心理韧性得分显著低于其他两组。应及时关注和干预小于60岁、失独年限<10年和低心理韧性的失独群体。     

失独父母创伤后应激障碍的症状结构、特征及预测因素

为考察我国失独父母创伤后应激障碍(PTSD)的症状特征及预测因素, 采用失独父母自身和孩子有关的基本信息问卷, 创伤后应激检查量表平民版(PCL-C), 对中国的463名失独父母进行调查。结果表明: (1)采用验证性因素分析验证了包括闯入、回避性、麻木性、精神痛苦性唤起和焦虑性唤起等5个因子的PTSD精神痛苦性唤起模型在中国失独父母中的适用性。(2)根据DSM-IV的诊断标准进行筛查, 71.92%的失独父母为PTSD阳性, 其中PTSD的回避、闯入、精神痛苦性唤起、情感麻木、焦虑性唤起因子阳性率依次增高。(3)失独父母的年龄、孩子的离世时长与PTSD症状具有显著的相关性; 失独父母的PTSD症状得分在自身性别、家庭所在地及家庭收入状况上存在显著差异; 将所有因素纳入回归方程后发现: 最能预测失独父母PTSD症状的因素包括: 性别、家庭所在地、年龄。     

服刑人员创伤后应激障碍与心理健康问题的共病类型

目的：采用潜在剖面分析服刑人员创伤后应激障碍(PTSD)与心理健康问题的潜在共病类型,并探讨创伤类型对潜在类别的影响。方法：采用PTSD筛查量表和一般健康问卷对692名服刑人员进行调查。结果：(1)PTSD与心理健康问题的共病类型可分为四类,即“高PTSD-高健康问题”、“回避-一般健康问题”、“低PTSD-高健康问题”和“低PTSD-低健康问题”;(2)相比于无创伤个体,遭遇创伤个体产生心理健康问题的风险更高,部分个体还有可能产生PTSD症状;而且,遭受人际创伤还更可能导致“回避-一般健康问题”(3)男性服刑人员较高的创伤率可能导致其在“低PTSD-高健康问题”和“回避-一般健康问题”的发生风险更高。     

价值观对蓄意创伤受害者创伤后应激障碍症状的影响

探讨价值观对蓄意创伤受害者创伤后应激障碍（Posttraumatic Stress Disorder ,简称PTSD）症状的影响方式。方法：采用事件冲击量表、受害人认可评价量表、施瓦兹价值观量表作为测查工具,测查了163 名蓄意创伤受害者。结果：（1）蓄意创伤受害者的PTSD三大症状表现有显著差异,闯入症状水平最高,回避症状水平次之,高警觉症状水平最低。（2）蓄意创伤受害者所持的价值观和对外界接纳的评价能较好地预测PTSD三大症状。（3）内敛价值类型通过诸如社会接纳等反映外在标准的因素影响PTSD的闯入症状。结论：蓄意创伤受害者PTSD症状表现有其自身的特点,对外界接纳的评价和自身所持的价值观对其PTSD症状有直接或间接的影响     

青少年感恩与创伤后应激障碍症状的关系:社会支持和心理弹性的中介作用

在"5.12"汶川地震后18个月时,采用青少年感恩量表、社会支持评定量表、心理弹性量表和创伤后应激障碍自评量表,对都江堰地区1439名经历地震的青少年进行问卷调查,考察感恩、社会支持、心理弹性与创伤后应激障碍(PTSD)症状的关系。结果表明:(1)感恩、社会支持和心理弹性均与PTSD症状呈显著的负相关,相关系数分别为-0.18,-0.17和-0.24;(2)感恩不仅直接影响PTSD症状,而且还通过社会支持和心理弹性的部分中介作用间接影响PTSD症状,中介效应占总效应的62%。     

术后乳腺癌患者体象对创伤后应激障碍和创伤后成长的影响：反刍的中介作用

为探讨乳腺癌患者反刍这一认知情绪调节方式在体象和创伤后应激障碍（PTSD）、创伤后成长（PTG）之间的中介作用，采用体象量表（BIS）、认知情绪调节问卷中文版（CERQ-C）、创伤后应激障碍量表（PSS）和创伤后成长问卷（PTGI）对150名乳腺癌术后患者进行研究。结果发现：（1）乳腺癌患者的体象可以正向预测PTSD和PTG；（2）乳腺癌患者的反刍在体象和PTSD的闯入性症状、回避性症状中起中介作用，在体象与PTG中的中介作用不显著。结果表明，体象既可以正向预测乳腺癌患者的PTSD和PTG，也可以通过反刍的中介作用影响PTSD。     

地震后青少年创伤后应激障碍的潜在结构分析

为考察地震后青少年创伤后应激障碍（PTSD）的潜在症状结构,本研究采用儿童创伤后应激障碍症状量表和儿童抑郁量表,对汶川地震一年后的746名中学生进行调查。利用验证性因素分析对竞争模型进行比较,结果发现包括侵入性、回避性、麻木性、精神痛苦性唤起和焦虑性唤起等5个症状的PTSD精神痛苦性唤起模型显著优于DSM-IV的PTSD模型、4维情感麻木模型和4维精神痛苦模型。效度分析的结果发现,PTSD精神痛苦性唤起模型具有良好的外部区分效度。所有结果均表明PTSD精神痛苦性唤起模型在汶川地震后青少年群体中具有良好的适用性,可以作为判定震后青少年PTSD症状的有效标准。     

创伤暴露程度对青少年物质滥用的影响：创伤后应激障碍与依恋的中介作用

为了考察汶川地震后青少年的创伤暴露程度、创伤后应激障碍（PTSD）、父母依恋和同伴依恋与物质滥用之间的关系,采用创伤暴露程度问卷、儿童创伤后应激障碍症状量表、父母与同伴依恋问卷和物质滥用问卷对汶川县和茂县的1435名中学生进行调查,选取有物质滥用的青少年354名作为本研究的对象。结果发现：创伤暴露程度可以直接正向预测作用物质滥用。不过,在创伤暴露与物质滥用直接关系之间加入PTSD、父母和同伴依恋之后,创伤暴露程度对物质滥用的直接预测作用不再显著,并且创伤暴露程度不能通过同伴依恋预测物质滥用,也不能通过PTSD经同伴依恋对物质滥用发挥多重中介作用;但创伤暴露程度能通过PTSD正向预测物质滥用,可以通过父母依恋负向预测物质滥用,并且创伤暴露程度还可以通过PTSD经过父母依恋对物质滥用发挥正向的多重中介作用。     

四川地震灾后中小学教师心理创伤评估报告

课题研究组对四川地震灾后重灾区和极重灾区的631名中小学教师创伤后应激障碍（PTSD）进行了调查,调查后对统计结果分析表明：（1）有PTSD重度症状表现的教师为18.7%;（2）极重灾区教师创伤显著高于重灾区教师;（3）青年教师的创伤要高于年长教师;（4）地震后部分教师感到内疚,无助,压抑,无信心,生命无意义,他们成为PTSD症状的易感人群     

社会支持对震后青少年创伤后应激障碍和创伤后成长的影响:自我效能感的中介作用

本研究采用创伤暴露问卷、社会支持问卷、自我效能感量表、创伤后应激障碍症状核查表和创伤后成长问卷,在汶川地震8.5年后对地震极重灾区的1185名中学生进行调查,考察社会支持对创伤后应激障碍（PTSD）和创伤后成长（PTG）的影响,并检验自我效能感在其中的中介作用。结果发现：在控制创伤暴露程度、性别和年龄等变量后,社会支持不仅可以直接负向预测PTSD、正向预测PTG,也可以通过自我效能感的中介作用负向预测PTSD、正向预测PTG。这表明,自我效能感在社会支持与PTSD、社会支持与PTG的关系中都具有部分中介效应。     

Cyclical variation in digit-span and visual-search performance in women differing in the severity of their premenstrual symptoms.

Groups of women differing in the severity of reported premenstrual symptoms were compared over two menstrual cycles on a digit-span task, a visual-search task, and a combination of the two. Neither group exhibited large performance changes during the premenstrual phase of the cycle. High-symptom women differed somewhat from low-symptom women in the effect of menstrual phase on digit-span performance, recalling slightly fewer series correctly during the premenstrual phase. The response latency of high-symptom women on the visual-search task was substantially longer than that of the low-symptom women regardless of menstrual phase. These results suggest that there may be stable differences between high-symptom and low-symptom subjects that are greater than the cyclical fluctuation within either group.     

Do traumatic events influence cognitive schemata?

Within the field of crisis psychology empirical research on the subject whether cognitive schemata are influenced by victimization, and whether possible changes in cognitive schemata are related to post-traumatic stress disorder (PTSD) is somewhat sparse. In the present study cognitive processing of 602 parents, who had lost an infant, were examined. Among other things results showed a significant relationship between level of cognitive processing and symptoms of PTSD. When items selected to reflect fundamental assumptions about the self and the world were assessed, there were only few differences between parents who had lost an infant, and the control group. Furthermore, there were numerous significant relations between items selected to reflect fundamental assumptions and symptoms of PTSD. The results are discussed in relation to central theories within the cognitive area of crisis psychology and recommendations for future research are offered.     

Resilience Variables and Posttraumatic Symptoms Among Maltreated Youth

Child maltreatment is associated with an array of social, behavioral, neurobiological, and developmental problems that can last for many years. A key outcome of child maltreatment includes posttraumatic stress symptoms such as reexperiencing, avoidance, and hyperarousal. Considerable research has focused on risk factors for posttraumatic symptoms in maltreated youth, but less so on possible protective factors such as resilience. This study examined several resilience variables (sense of mastery, sense of relatedness, emotional reactivity) in an ethnically diverse sample of maltreated adolescents with posttraumatic symptoms. Key aspects of resilience that predicted posttraumatic stress disorder (PTSD) symptoms included sense of mastery (for fewer symptoms) and emotional reactivity (for more symptoms). In particular, optimism, self-efficacy, and adaptability were inversely related to PTSD symptoms. In addition, emotional reactivity moderated a relationship between resilience resource scores and PTSD symptoms. The findings appeared to apply most to sexually maltreated youth. The results preliminarily demonstrate the importance of considering resilience-based variables during clinical processes for maltreated youth.     

Parent and Family Characteristics and Their Associates in a Follow-Up of Outpatient Children with ADHD

We examined associations between child symptoms, demographic variables, parent and family characteristics in a long-term follow-up study of 214 outpatient children with attention-deficit/hyperactivity disorder (ADHD). The children’s mean age was 12.6 (SD = 2.1) years, and the mean interval from diagnosis to follow-up was 3.7 (SD = 2.2) years. We compared the characteristics of the clinical group with a community group (n = 110) recruited from the same catchment area. Parents filled out questionnaires on child symptoms, parent characteristics, and family functioning. The results showed that parents of young boys (<13 years) experienced more parenting stressors than those of adolescent boys (≥13 years), but the opposite was true for parents of girls. Parents of children with both ADHD and oppositional defiant disorder symptoms in the clinical range experienced significantly more parent and family dysfunctions than those of children with ADHD only (even after controlling for levels of ADHD symptoms in the child). Parents of children in the community group experienced significantly less parent and family dysfunctions than those of children with ADHD. Partial correlations between parent characteristics and child symptoms showed that oppositional symptoms were most strongly associated with parent and family dysfunction. Fathers experienced significantly less parenting stress, parental efficacy, and child involvement than mothers. We conclude that parents of children with ADHD experienced considerable strain related to a broad range of parent and family characteristics. Assessment of such characteristics should be part of routine assessment procedures and a prerequisite for family-focused treatment of children with ADHD.     

Testing a Military Family Stress Model

The current study examines a military family stress model, evaluating associations between deployment‐related stressors (i.e., deployment length/number, posttraumatic stress disorder [PTSD] symptoms) and parent, child, parenting, and dyadic adjustment among families in which a parent had previously deployed to Iraq or Afghanistan in the recent conflicts. Married families (N = 293) with at least one child between the ages of 4 and 12 were recruited from a Midwestern state. Service members were from the Reserve Component (National Guard or Reserves); fathers (N = 253) and/or mothers had deployed (N = 45) to the recent conflicts in the Middle East. Multiple‐method (observations of parenting and couple interactions; questionnaires) and multiple informant measures were gathered online and in the homes of participants, from parents, children, and teachers. Findings demonstrated associations between mothers’ and fathers’ PTSD symptoms and a latent variable of child adjustment comprising teacher, parent, and child report. Mothers’ but not fathers’ PTSD symptoms were also associated with dyadic adjustment and parenting practices; parenting practices were in turn associated with child adjustment. The results are discussed in terms of their implications for military family stress research and interventions to support and strengthen parents and families after deployment.     

Identifying Changes in Youth's Subgroup Membership Over Time Based on Their Targeted Communication About Substance Use with Parents and Friends

Using latent class/transition analyses, this study: (a) identified subgroups of youth based on their targeted communication about substance use with parents and friends, (b) examined subgroup differences in substance use, and (c) considered changes in subgroup membership over four years. Among 5,874 youth, five subgroups emerged, with parents‐only communicators having the lowest substance use. Friends‐only and consequence‐focused communicators reported the overall highest use. Subgroup membership was mostly stable across the four years. If, however, youth transitioned, those who began as parents‐only, consequence‐focused, or friends‐only communicators during the first year were most likely to transition to comprehensive communicators by the last year. Youth who started as noncommunicators or comprehensive communicators were most likely to end up as parents‐only communicators.     

Parent-Child Endorsement Discrepancies among Youth at Chronic-Risk for Depression

Depression is one of the most common mental health problems among U.S. adolescents, particularly among Latinos. Parent-child ratings of the presence and severity of child depressive symptoms show only low-to-moderate agreement. However, research has failed to examine discrepancies in populations with the highest levels of unmet need and little is known about patterns and predictors of parent-child agreement in ratings of depressive symptoms among ethnic minority families in community settings. Using a sample of 184 low-income, predominantly Latino, 5th through 7th grade students (63.6% female) at chronic risk for depression, this study utilized exploratory Latent Class Analysis (LCA) to uncover patterns of parent-child endorsement of core diagnostic depressive symptoms. Overall, children reported higher levels of core (i.e., depressed mood, anhedonia, irritability) and secondary (e.g., sleep disturbances) depressive symptoms relative to their parents. The three latent classes identified include a low endorsement and high agreement class (LH), high endorsement and high agreement class (HH), and high child endorsement and low agreement class (HCL). Multinomial regression models revealed that previous mental health service use and higher externalizing problems were associated with HH class membership, relative to HCL class membership. Findings provide evidence that a substantial number of children may have depressive symptoms that go undetected by their parents. Access to services among children at-risk for depression may be increased with psychoeducation to improve parental awareness and stigma reduction.
