Combat-exposed military personnel from the wars in Iraq and Afghanistan report high rates of PTSD and associated psychiatric problems. A formidable body of research supports exposure therapy as a front-line intervention for PTSD; however, relative to studies of civilians, fewer investigations have evaluated the effectiveness of exposure therapy using military samples. Specifically, barriers to care (e.g., stigma associated with receiving mental health services ) may compromise utilization of evidence-based psychotherapy. As such, researchers have argued that veterans with PTSD may require an integrated and innovative approach to the delivery of exposure techniques. This paper presents the rationale for and preliminary data from an ongoing clinical trial that compares the home-based telehealth (HBT) application of a brief, behavioral treatment (Behavioral Activation and Therapeutic Exposure; BA-TE) for veterans with PTSD to the standard, in-person application of the same treatment. Forty OIF/OEF veterans with PTSD and MDD were consented, enrolled, and randomized to condition (BA-TE in-person, or BA-TE HBT) and symptoms of anxiety and depression were assessed at pre- and posttreatment. Participants in both conditions experienced reductions in depression, anxiety, and PTSD symptoms between pre- and posttreatment, suggesting that HBT application of an integrated PTSD treatment may be feasible and effective. 相似文献

This study of infant declarative memory concurrently examined brain-electrical activity and deferred imitation performance in 10-month-old infants. Continuous electroencephalogram (EEG) measures were collected throughout the activity-matched baseline, encoding (modeling) and retrieval (delayed test) phases of a within-subjects deferred imitation task. Infants were divided into two memory performance groups based on the exhibition of ordered-recall after a 24-h delay. Whereas no group differences were found in EEG collected during encoding, performance-group differences in EEG were present during retrieval. Infants who successfully displayed ordered-recall showed a pattern of increasing EEG from baseline to task at anterior temporal scalp locations, whereas infants showing no ordered-recall displayed no changes in EEG from baseline to task. These findings are discussed with respect to the biobehavioral developments underlying declarative memory abilities. 相似文献

There is controversy whether asymptomatic first-degree relatives (FDRs) of patients with venous thromboembolism (VTE) and
thrombophilia should be screened, followed, and prescribed prophylaxis during risk periods. We recruited consecutive probands
with idiopathic VTE and thrombophilia from our thrombosis clinics. Those FDRs with thrombophilia were randomized in family
clusters to receive one-time verbal counseling and no organized follow-up or counseling, educational material, reminder aids
and follow-up. Only 203 of 1,129 FDRs were eligible and consented. Dropouts were common; 1 FDR (1.7%) developed VTE. VTE risk,
ability to treat and prevent were underestimated by the participants. Patients with VTE and thrombophilia and their FDRs are
often not interested in thrombophilia testing. Despite education to inform their knowledge, interest and follow-up were less
than ideal. The question of the best educational approach in these patients remains unanswered. The value of testing and following
asymptomatic carriers of probands with VTE and thrombophilia remains unknown. 相似文献

This study examines risk comparative judgments and risky behaviors while driving a car among competitive road cyclists (n = 119) and among controls (i.e., drivers who have almost no cycling experience, n = 142). A questionnaire-based cross-sectional survey was conducted. Results showed that competitive road cyclists assess their own vulnerability to be involved in an accident while riding (VAR) as being lower than that of the average cyclists, and their abilities to manage risks while riding (AMRR) as being higher. They assessed their own vulnerability to be involved in an accident while driving a car (VAD) as being lower than that of the average drivers, and their own quality of reflexes while driving a car (QRD) as being higher. Their tendency to express comparative optimism while assessing their comparative VAD and QRD was higher than that of controls. They also reported more prudent behaviors while driving a car than did controls. Results are discussed, as well as implications in terms of prevention. 相似文献

A study of object naming in 202 children, aged 5–11 years, demonstrated that varying the stimulus context affected the level of response accuracy. From age 6 to 10, completing a sentence with a noun (auditory) yielded the lowest error scores, naming objects upon hearing a definition (also auditory) produced most errors, while responding with names to pictured objects was of intermediate difficulty. This is the same order of object naming difficulty found in adult aphasic patients. Children older than 10 do not appear to be affected by stimulus context in their object naming. Results are discussed in terms of the relative syntactic difficulty of the two auditory conditions, the unexpected sex differences, and the “aphaseoid” naming errors of children. 相似文献

The current study examined the relationship between intimate partner violence (IPV), maternal parenting behaviors, and child effortful control in a diverse sample of 705 families living in predominantly low-income, rural communities. Using structural equation modeling, the authors simultaneously tested whether observed sensitive parenting and/or harsh-intrusive parenting over the toddler years mediated the relationship between early IPV and later effortful control. Results suggest that parenting behaviors fully mediate this relationship. Although higher levels of IPV were associated with both higher levels of harsh-intrusive parenting and lower levels of sensitive supportive parenting, only sensitive supportive parenting was associated with later effortful control when both parenting indices were considered in the same model. 相似文献

The election of the first African‐American President of the United States, Barack Obama, has been widely recognised as an extraordinary milestone in the history of the United States and indeed the world. With the use of a discursive psychological approach combined with central theoretical principles derived from social identity and self‐categorisation theories, this paper analyses a corpus of speeches Obama delivered during his candidacy for president to examine how he attended to and managed his social identity in his political discourse. Building on a social identity model of leadership, we examine specifically how Obama mobilises political support and social identification by building an identity for himself as a prototypical representative of the American people, notwithstanding the protracted public debate within both the White and Black American communities that had questioned and contested Obama's identity. Moreover, we demonstrate how Obama managed the dilemmas around his identity by actively crafting an in‐group identity that was oriented to an increasingly socially diverse America—a diversity that he himself exemplified and embodied as a leader. As an ‘entrepreneur’ of identity, Obama's rhetorical project was to position himself as an exceptional leader, whose very difference was represented as ‘living proof’ of the widely shared collective values that constitute the ‘American Dream’. Drawing on social identity complexity theory, we suggest that by providing more inclusive and complex categories of civic and national identity, Obama's presidency has the potential to radically transform what it means to be a prototypical in‐group member in America.

While the public debate on whether to apologise to the Stolen Generations ended on 13 February, 2008, public opinion was still divided, reflected particularly in the arguments against apologising that were common in political and public discourse. We examine the ways in which differing arguments can be flexibly deployed and combined within a political context to not just resist, but also to support, an act of reparation for historical injustice. In particular, we consider how Rudd makes use of specific rhetorically self‐sufficient arguments to justify offering the apology; precisely the same arguments that had previously been used by political leaders and members of the public to oppose the apology. It is the use of such arguments in combination with each other and additional common tropes drawn from egalitarian and liberal discourse that allow for the building of a rhetorically powerful case for offering the apology. Rather than the traditional focus of such research on the ways in which racism is accomplished in talk, we suggest that Rudd's apology to the Stolen Generations can be seen as a practical tool‐kit for building an “anti‐racist” rhetoric in the context of Indigenous and non‐Indigenous relations in Australia. 相似文献
