Background/ObjectiveThe current study aimed to examine the relationship between Posttraumatic Stress Disorder (PTSD) symptoms and executive dysfunction in children and adolescents after psychological trauma.MethodParticipants were 13,438 of children and adolescents aged 6 to 18 years exposed to the 2008 Wenchuan earthquake. PTSD and dysexecutive symptoms were assessed using the UCLA PTSD Reaction Index for Children and the Self-Report Dysexecutive Questionnaire. Latent Profile Analysis (LPA) was conducted using Mplus version 7.4. Subgroup differences in trauma exposure and quality of life were calculated using ANCOVA.ResultsA 4-class parallel model was found to best describe latent PTSD symptom profiles and executive dysfunction. Individuals in higher symptom groups showed more trauma exposure and lower quality of life.ConclusionsThis LPA study shed light on the relationship between PTSD and executive dysfunction symptoms in children and adolescents. The correlation between PTSD and executive dysfunction was maintained after individual differences were taken into consideration. Our findings provide a new view on how PTSD relates to executive dysfunction and several suggestions for treating child and adolescent PTSD patients. 相似文献

The present study investigated mindfulness‐based stress reduction (MBSR) for young adults with a social anxiety disorder (SAD) in an open trial. Fifty‐three young adults in a higher education setting underwent a standard eight‐week MBSR program. Eight participants (15%) did not complete the program. Participants reported significant reductions in SAD symptoms and global psychological distress, as well as increases in mindfulness, self‐compassion, and self‐esteem. Using intention‐to‐treat (ITT) analyses, effect sizes ranged from large to moderate for SAD symptoms (Cohen's d = 0.80) and global psychological distress (d = 0.61). Completer analyses yielded large effect sizes for SAD symptoms (d = 0.96) and global psychological distress (d = 0.81). The largest effect sizes were found for self‐compassion (d = 1.49) and mindfulness (d = 1.35). Two thirds of the participants who were in the clinical range at pretreatment reported either clinically significant change (37%) or reliable improvement (31%) on SAD symptoms after completing the MBSR program, and almost two thirds reported either clinically significant change (37%) or reliable improvement (26%) on global psychological distress. MBSR may be a beneficial intervention for young adults in higher education with SAD, and there is a need for more research on mindfulness and acceptance‐based interventions for SAD. 相似文献

Given the significant modifications to posttraumatic stress disorder (PTSD) symptom criteria from DSM-IV to DSM-5, a better understanding of the dimensionality underlying DSM-5 PTSD symptoms among adolescents is needed. However, to date, whether gender moderates the latent structure of DSM-5 PTSD symptoms in youth remains unclear. Meanwhile, little is known about how distinct PTSD dimensions relate to adolescent behavioral problems. The aim of this study was to fill these gaps. A sample of 1184 disaster-exposed Chinese adolescents (53.8 % girls) with age ranging from 13 to 17 years (M = 14.3, SD = 0.8) completed the PTSD Checklist for DSM-5, and the Withdrawn, Aggressive Behavior, and Delinquent Behavior subscales of the Youth Self-Report. Confirmatory factor analyses revealed that the seven-factor hybrid PTSD model provided the best fit to the data for both girls and boys. Measurement equivalence of this model held across gender, although girls had higher mean scores than boys on some factors. Differential patterns of associations emerged between PTSD dimensions and behavioral problems, with anhedonia symptoms most strongly relating to social withdrawal, and externalizing behavior symptoms most strongly relating to aggression and delinquency. These findings further support the gender invariance and external criterion validity of the newly refined hybrid model that best represents DSM-5 PTSD symptom structure in youth, and carry implications for accurate assessment, diagnosis, and gender comparison of DSM-5 PTSD symptomatology, and potential symptom targets for PTSD intervention among adolescent disaster survivors. 相似文献

Racial Attitudes Predicted Changes in Ostensibly Race‐Neutral Political Attitudes Under the Obama Administration 下载免费PDF全文

Past research demonstrated that racial prejudice played a significant role in the 2008 presidential election, but relatively less is known about the relationship between prejudice and public opinion throughout the Obama administration. In the present research, we examined not only whether racial attitudes were associated with evaluations of Mr. Obama and his administration, but also whether they may have influenced the development of more general political attitudes during the early years of the Obama administration. We investigated this question using panel data from a nationally representative sample of Americans interviewed between September 2008 and July 2010. Racial attitudes measured prior to the election predicted early disapproval of President Obama's handling of important issues. Early disapproval of President Obama's performance, in turn, predicted later perceptions of whether the state of the nation was improving. Further, the divergence between high‐prejudice and low‐prejudice individuals in their perceptions of the state of the nation became greater over time, consistent with the idea that racial attitudes were more powerfully expressed in political judgments as time passed. 相似文献

It is widely argued that people with autism have difficulty processing ambiguous linguistic information in context. To investigate this claim, we recorded the eye-movements of 24 adolescents with autism spectrum disorder and 24 language-matched peers as they monitored spoken sentences for words corresponding to objects on a computer display. Following a target word, participants looked more at a competitor object sharing the same onset than at phonologically unrelated objects. This effect was, however, mediated by the sentence context such that participants looked less at the phonological competitor if it was semantically incongruous with the preceding verb. Contrary to predictions, the two groups evidenced similar effects of context on eye-movements. Instead, across both groups, the effect of sentence context was reduced in individuals with relatively poor language skills. Implications for the weak central coherence account of autism are discussed. 相似文献

ABSTRACT We tested a theoretical model of personality structures underlying patterns of intra-individual variability in contextualized appraisals. The KAPA (Knowledge-and-Appraisal Personality Architecture) model was tested experimentally among smokers appraising their efficacy to resist the urge to smoke in high-risk situations. In a novel design, we assessed self-knowledge and situational beliefs idiographically and employed cognitive priming to manipulate the accessibility of self-knowledge experimentally. The results confirmed the unique KAPA-model prediction that priming would affect appraisals in a contextualized manner. Priming positively valenced self-knowledge enhanced self-efficacy appraisals specifically within that subset of situations that were relevant to the primed knowledge. The results were consistent with the hypothesis that systems of self- and situational knowledge underlie consistency and variability in appraisals. 相似文献

Many animal species use reaching for food to place in the mouth (reach-to-eat) with a hand, and it may be a primitive movement. Although researchers (I. Q. Whishaw, 2005; A. N. Iwaniuk & I. Q. Whishaw, 2000; M. Gentiluci, I. Toni, S. Chieffi, & G. Pavesi, 1994) have described visual guidance of reaching in both normal and brain-injured human and nonhuman primates, researchers have not described the contribution of vision during advance of the limb to grasp food and during withdrawal of the limb with food to the mouth. To evaluate visual contributions, the authors monitored eye movements in young adults as they reached for food with and without vision. Participants visually engaged the target prior to the 1st hand movement and disengaged it as the food was grasped. Visual occlusion slowed limb advance and altered digit shaping but did not affect withdrawal. The dependence on visual control of advance but not withdrawal suggests that the reach-to-eat movement is a composite of 2 basic movements under visual and tactile/proprioceptive guidance, respectively. 相似文献

Research in psychology has reported that, among the variety of possibilities for assessment methodologies, summary evaluation offers a particularly adequate context for inferring text comprehension and topic understanding. However, grades obtained in this methodology are hard to quantify objectively. Therefore, we carried out an empirical study to analyze the decisions underlying human summary-grading behavior. The task consisted of expert evaluation of summaries produced in critically relevant contexts of summarization development, and the resulting data were modeled by means of Bayesian networks using an application called Elvira, which allows for graphically observing the predictive power (if any) of the resultant variables. Thus, in this article, we analyzed summary-evaluation decision making in a computational framework. 相似文献
