Community reintegration (CR) is a challenge for military veterans with traumatic brain injury (TBI). Posttraumatic stress disorder (PTSD), depression, bodily pain, and limitations in physical functioning—common comorbidities with TBI in veterans—have all been associated with problems in CR, but their interrelationships are unclear. The role of depression as a possible mediator of effects on CR has not been examined. We tested depressive symptoms as a possible mediator of CR’s associations with physical limitations, PTSD, and bodily pain. This cross-sectional study used baseline data from a larger randomized controlled trial that evaluated the impact of an in-home intervention for veterans with TBI and their families. Eighty-three military veterans with TBI recruited from a medical rehabilitation service at an urban U.S. Department of Veterans Affairs medical center participated in the study. Interview instruments measured CR, depressive symptoms, physical limitations (limitations in physical functioning), bodily pain, quality of the relationship with key family members, and sociodemographic characteristics. PTSD was determined through review of the electronic medical record. Interview data were collected in veterans’ homes. Depressive symptoms totally mediated the association between physical limitations and CR and the association between PTSD and CR. The bodily pain–CR association was not significant after quality of relationship had been entered into the regression models. Findings suggest that interventions to increase CR of veterans with TBI should address depression, a treatable condition. Replication of our mediation findings in larger veteran and civilian samples with TBI is needed. 相似文献

Negative emotional responses to sex such as anxiety, guilt and fear tend to inhibit sexual behavior. When they are not sufficient to inhibit sexual intercourse, however, they frequently interfere with the ability to plan for, or cope with the consequences of sexual activity. More specifically, these emotional responses to sex frequently interfere with the ability to apply thoughtful and careful logic to contraceptive decision making, and thereby inhibit the use of effective methods of birth control. The current article is a review of the empirical support for emotional inhibition of contraception, and an examination of the psychological mechanisms by which these responses to sex mediate birth control behavior. 相似文献

This prospective study examined the relation between 308 adolescents' images of typical dinkers and nondrinkers and their subsequent alcohol consumption. The results indicate that both images are associated with changes in consumption between ages 16 and 18 but that they operate in different ways. Contrary to previous assumptions, drinker images do not represent goal states for adolescents in that they are more negative than their self-images and nondrinker images and are not correlated with their ideal selves. In contrast, nondrinker images do appear to represent goal states for adolescents who abstain from drinking. Implications for intervention are discussed. 相似文献

注意控制和短时存储对音位流畅性和语义流畅性的影响 总被引:2,自引:0,他引:2
工作记忆的中央执行系统具有注意控制和短时存储的功能。采用双任务范式,探讨了中央执行系统的注意控制和短时存储对言语流畅性的影响。实验1考察了中央执行系统的转换和抑制功能对音位流畅性和语义言语流畅性的影响。结果表明,中央执行系统的转换和抑制功能对两种言语流畅性的影响相当。实验2考察了中央执行系统的注意控制资源和短时存储资源对两种言语流畅性的影响。结果表明,语义流畅性更依赖于短时存储资源,音位流畅性更依赖于注意控制资源。研究还发现,被试完成语义流畅性任务的策略更易受概念系统的特性影响,完成音位流畅性任务的策略更易受语言的特点影响。在实验研究的基础上,作者提出了工作记忆影响言语流畅性的理论模型 相似文献

The authors tested 2 mechanisms for the relation of movie smoking exposure with onset of cigarette smoking in adolescence. Longitudinal data with 8-month follow-up were obtained from a representative sample of 6,522 U.S. adolescents, ages 10-14 years. Structural modeling analysis based on initial nonsmokers, which controlled for 10 covariates associated with movie exposure, showed that viewing more smoking in movies was related to increases in positive expectancies about smoking and increases in affiliation with smoking peers, and these variables were both related to smoking onset. A direct effect of movie exposure on smoking onset was also noted. Mediation findings were replicated across cross-sectional and longitudinal analyses. Tests for gender differences indicated that girls showed larger effects of movie exposure for some variables. Implications for policy and prevention research are discussed. 相似文献

采用学习-迁移模式, 探讨了同时学习和继时学习两种方式下归类不确定时的特征推理。共包括2个实验, 其中实验1探讨了固定学习轮次的情况, 实验2探讨了固定学习正确率的情况。实验结果表明:同时呈现类别要素的同时学习方式下, 被试习得序列式的单类别表征(原型表征), 在归类不确定时的特征推理中按照“单类的Bayesian规则”进行特征推理, 即P(j\F) =P(k\F)·P(j\k); 相继呈现类别要素的继时学习方式下, 被试习得并列式的多类别表征, 在归类不确定时的特征推理中按照“理性模型”进行推理, 即 P(j\F) =Σk P(k\F)·P(j\k)。 相似文献
