Intrusive images and memories in major depression 总被引:1,自引:1,他引:0

Individuals with current major depression were interviewed to investigate the prevalence of distressing intrusive mental imagery among depressed patients and study the phenomenology of these intrusions. Of the 39 currently depressed patients, 17 experienced some form of repetitive intrusive imagery (i.e., either an intrusive memory or image), with intrusive memories being more common than images. The intrusive imagery was experienced as highly uncontrollable and interfered significantly with patients' everyday lives. The intrusions were experienced with a sense of 'nowness', as well as physical and emotional re-experiencing. Despite high levels of re-experiencing, levels of dissociation were very low. The intrusive imagery was in some patients part of a wider network of key defining autobiographical memories, consistent with the idea that it is likely to play a significant role in maintaining the patient's depressive mood. Interventions targeting these intrusions could potentially result in a positive shift in depressed mood. 相似文献

This study investigated the prevalence of hypoglycemic fear (FH) and hypoglycemia-specific posttraumatic stress (PTS) among
individuals with Type I diabetes. Over 25% of participants met diagnostic criteria for current PTSD. High percentages of participants
endorsed PTS symptom clusters, suggesting that individuals may be experiencing distress without necessarily meeting diagnostic
criteria. Hierarchical multiple regression analyses revealed that perceived threat of death from hypoglycemia and FH were
significantly related to PTS. Number of recent hypoglycemic episodes did not predict PTS/PTSD. Depression and nonspecific
anxiety did not contribute to the statistical prediction of PTSD, suggesting that symptomatology endorsed represents hypoglycemia-specific
anxiety rather than global psychological distress. The hypothesis that greater PTS symptomatology would relate to poorer glycemic
control was unsubstantiated. Perceived death-threat from hypoglycemia and nonspecific anxiety were the only variables that
contributed to prediction of glycemic control, suggesting that PTS did not represent a significant barrier for glycemic control
in this sample. 相似文献

Whole exome sequencing (WES) is an integral tool in the diagnosis of genetic conditions in pediatric patients, but concerns have been expressed about the complexity of the information and the possibility for secondary findings that need to be conveyed to those deciding about WES. Currently, there is no validated tool to assess parental understanding of WES. We developed and implemented a survey to assess perceived and actual understanding of WES in parents who consented to clinical WES for their child between July 2013 and May 2015. Fifty-three eligible surveys were returned (57% response rate). Areas with both low perceived and actual understanding about WES included how genes are analyzed and lack of protection against life insurance discrimination. Parents also had low actual understanding for two questions related to secondary findings – reporting of secondary findings in a parent (if tested) and whether secondary findings can be related to traits such as height and hair color. Further work to develop a validated tool to assess understanding of WES would be beneficial as WES is integrated more frequently into clinical care. 相似文献

The Psychological Trauma and Psychological Resources Scale has been developed to identify adolescents and adults who have experienced traumatic events, i.e., physical, sexual, or emotional abuse and neglect. The scale also attempts to identify the presence of compensatory or resource factors such as social support that may serve to ameliorate the effects of traumatic events. 98 college participants who reported a history of abuse were compared with 464 nonabused students on the seven subscales. As predicted, the abused participants reported significantly more incidents of abuse and neglect than the nontraumatized group. In addition, the abused group reported receiving less emotional support, and they were less likely to use positive self-talk as a way to decrease emotional distress. These results provide empirical support for using the Psychological Trauma and Psychological Resources Scale to identify individuals with a history of abuse. Findings underscore the importance of assessing resource variables that may moderate the effects of abuse. 相似文献

Six cases of serial murder by children and adolescents spanning the past 150 years are presented. The available literature pertaining to this area is reviewed. Each of these six offenders committed sexually homicidal behavior as demonstrated by their expression of erotic interest or engagement in overt sexual behavior at the crime scenes. From a DSM-IV-TR perspective they all exhibited signs of sexual sadism, and their crime characteristics reflected behavior of a more predatory than affective nature. Hands on methods of killing were preferred, i.e., cutting, stabbing, or strangulation. These crimes are extremely rare. Case reports in this area are encouraged to advance our knowledge of these youths. 相似文献

This study investigated the relationship between scores of college students (N=210, 114 women, 95 men, 1 unidentified; Mage=19.3 yr., SD=2.8) on Machiavellianism and their motives for communicating with their instructors in the classroom. Students' Machiavellianism scores were positively but weakly related to three motives of Functional (r=.22, p<.01), Excuse-making (r=.16, p<.05), and Sycophancy (r=.17, p<.05). 相似文献

By integrating previous computational models of corticohippocampal function, the authors develop and test a unified theory of the neural substrates of familiarity, recollection, and classical conditioning. This approach integrates models from 2 traditions of hippocampal modeling, those of episodic memory and incremental learning, by drawing on an earlier mathematical model of conditioning, SOP (A. Wagner, 1981). The model describes how a familiarity signal may arise from parahippocampal cortices, giving a novel explanation for the finding that the neural response to a stimulus in these regions decreases with increasing stimulus familiarity. Recollection is ascribed to the hippocampus proper. It is shown how the properties of episodic representations in the neocortex, parahippocampal gyrus, and hippocampus proper may explain phenomena in classical conditioning. The model reproduces the effects of hippocampal, septal, and broad hippocampal region lesions on contextual modulation of classical conditioning, blocking, learned irrelevance, and latent inhibition. 相似文献

When we read that two protagonists in a story chatted together for a couple of minutes, do we draw inferences about the topic of the conversation on the basis of information presented earlier in the text? Participants read passages in which protagonists part and later reunite; the passages ended with a sentence either that implied conversation or did not. In Experiment 1, participants' continuation sentences indicated that inferences about the topic of conversation were drawn. Recognition probe data in Experiment 2 provided more immediate evidence of such inferences. Experiment 3 addressed a possible confound in Experiment 2 and again provided evidence that readers inferred the continuation of the conversation. In Experiments 4 and 5, we investigated the effect of having the targeted conversational topic be a secret that should not be shared between the protagonists. The results are discussed in terms of the collaboration between passive, memory-based text processing and schema-driven comprehension processes. 相似文献

Rules of thumb for power in multiple regression research abound. Most such rules dictate the necessary sample size, but they are based only upon the number of predictor variables, usually ignoring other critical factors necessary to compute power accurately. Other guides to power in multiple regression typically use approximate rather than precise equations for the underlying distribution; entail complex preparatory computations; require interpolation with tabular presentation formats; run only under software such as Mathmatica or SAS that may not be immediately available to the user; or are sold to the user as parts of power computation packages. In contrast, the program we offer herein is immediately downloadable at no charge, runs under Windows, is interactive, self-explanatory, flexible to fit the user's own regression problems, and is as accurate as single precision computation ordinarily permits. 相似文献
