The identification of high-risk adolescent suicide attempters in a population of depressed and suicidal adolescents is of crucial importance. This retrospective study examined characteristics of suicidality (recent and lifetime, active and passive) and psychopathology (depression, aggression, impulsivity, stressful life events, SCL-90 dimensions) among four groups of depressed adolescent outpatients: (1) suicide attempters who required medical treatment (n = 84), (2) suicide attempters who did not require medical treatment (n = 57), (3) suicidal ideators who had never made a suicide attempt (n = 40), and (4) nonsuicidal patients (n = 44). Results indicate that the nonsuicidal group could be differentiated from the three suicidal groups on the basis of suicidality and psychopathology, and that the three suicidal groups could be differentiated from one another on the basis of suicidality but not psychopathology. These findings are discussed in terms of the usefulness of certain self-report measures of suicidality for identifying suicidal adolescents and for differentiating among them. Furthermore, the findings suggest that psychopathological factors do not determine which suicidal adolescents make a medically dangerous suicide attempt and which do not. 相似文献

Poor inhibitory control over negative emotional information has been identified as a possible contributor to affective disorders, but the distinct effects of emotional contrast and fearful versus angry faces on response inhibition remain unknown. In the present study, young adults completed an emotional go/no-go task involving happy, neutral, and either fearful or angry faces. Results did not reveal differences in accuracy or speed between angry and fearful face conditions. However, responses were slower and indicated poorer inhibition in blocks where threatening faces were paired with happy, versus neutral, faces. Results may reflect cognitive load of emotional valence contrast, such that higher contrast blocks (containing threatening with happy faces) produced more conflict and required more processing than lower contrast blocks (threatening with neutral faces). Preliminary findings also revealed higher anxiety and depression symptoms corresponded with slower responses and worse accuracy, consistent with patterns of adverse impacts of anxiety and depression on response inhibition to threatening faces, even at subclinical levels of symptomatology. 相似文献

This article explores teaching self-compassion as a means of self-care for counseling graduate students. Self-care is vital to helping professionals, but few students learn specific self-care skills to integrate into their own self-care practice. Self-compassion is a simple practice used in the immediate moment or as an activity at home. The authors describe Kristen Neff’s model of self-compassion. The authors discuss the benefits of self-compassion as self-care and explain its practice as an effective avenue to increase compassion and relationship building with clients. In addition, they clarify how self-compassion practices strengthen relational connection. The writers describe three examples of self-care practices, and share suggestions for counselor educators to integrate self-care into graduate counselor training. 相似文献

Loss of insight is a prominent clinical manifestation of behavioral variant frontotemporal dementia (bvFTD), but its characteristics are poorly understood. Twelve bvFTD patients were compared with 12 Alzheimer’s disease (AD) patients on a structured insight interview of cognitive insight (awareness of having a disorder) and emotional insight (concern over having a disorder). Compared to the AD patients, the bvFTD patients were less aware and less concerned about their disorder, and they had less appreciation of its effects on themselves and on others. After corrective feedback (“updating”), the bvFTD patients were just as aware of their disorder as the AD patients but remained unconcerned and unappreciative of its effects. These findings suggest that lack of insight in bvFTD is not due to “anosognosia,” or impaired cognitive and executive awareness of disease, but to “frontal anosodiaphoria,” or lack of emotional concern over having bvFTD and its impact on themselves and others. 相似文献

BDNF regulates components of cognitive processes and has been implicated in psychiatric disorders. Here we report that genetic overexpression of the BDNF mature isoform (BDNF-tg) in female mice impaired working memory functions while sparing components of fear conditioning. BDNF-tg mice also displayed reduced breeding efficiency, higher anxiety-like scores, high self-grooming, impaired prepulse inhibition, and higher susceptibility to seizures when placed in a new empty cage, as compared with wild-type (WT) littermate controls. Control measures of general health, locomotor activity, motor coordination, depression-related behaviors, and sociability did not differ between genotypes. The present findings, indicating detrimental effects of life-long increased BDNF in mice, may inform human studies evaluating the role of BDNF functional genetic variations on cognitive abilities and vulnerability to psychiatric disorders. 相似文献

Interactions between statistical and semantic information in infant language development 总被引:1,自引:0,他引:1
Infants can use statistical regularities to form rudimentary word categories (e.g. noun, verb), and to learn the meanings common to words from those categories. Using an artificial language methodology, we probed the mechanisms by which two types of statistical cues (distributional and phonological regularities) affect word learning. Because linking distributional cues vs. phonological information to semantics make different computational demands on learners, we also tested whether their use is related to language proficiency. We found that 22-month-old infants with smaller vocabularies generalized using phonological cues; however, infants with larger vocabularies showed the opposite pattern of results, generalizing based on distributional cues. These findings suggest that both phonological and distributional cues marking word categories promote early word learning. Moreover, while correlations between these cues are important to forming word categories, we found infants' weighting of these cues in subsequent word-learning tasks changes over the course of early language development. 相似文献

Understanding the relationship between depression and suicidal behavior among individuals with schizophrenia and schizoaffective disorder can aid assessment and treatment. In this study, 86 individuals with schizophrenia and schizoaffective disorder were assessed for past and current suicidal behavior, depression, hopelessness, and reasons for living. Thirty-four percent reported a history of suicide attempts. Suicidal behavior typically occurred 4.5 years after the onset of psychosis and 7.5 years after the onset of the first major depressive episode for those who had a history of major depression. Depression was frequent among both attempters and non-attempters, but only half of the attempters reported a suicide attempt during an episode of major depression. And almost half of those with depression never made a suicide attempt despite a long history of illness. Although depression is a potential stressor for triggering suicidal behavior in a vulnerable subset of individuals with schizophrenia, schizophrenia research must identify other risk factors for suicidal behavior. Clinicians should remember that even without a depressive episode there is still a significant risk for suicidal behavior in schizophrenia. 相似文献
