This study examined the relation between children's history of exposure to potentially traumatic events (PTEs) and clinical and functional mental health trajectories over a 18‐month period among a national sample of youth referred for services in children's behavioral health systems of care (SOCs). Using data from the national evaluation of the Comprehensive Community Mental Health Services program for communities funded from 1997 to 2000, the study sample included 9556 children and their families. Latent growth modeling was used to assess the effect of history of exposure to PTEs on trajectories in a number of behavioral health outcomes during the 3‐year period following referral to services, controlling for child demographic characteristics (gender, race, and age). Results revealed that, on average, children in SOCs exhibited significant improvements over time on all four outcome measures. Children with a history of exposure to PTEs had higher rates of internalizing and externalizing problem behaviors and functional impairments and fewer behavioral and emotional strengths at baseline, but experienced improvements in these outcomes at the same rates as children without exposure to a traumatic event. Finally, child race, gender, and age also were associated with differences in behavioral health trajectories among service recipients. Implications for SOCs, including approaches to make them more trauma‐informed, are discussed.  相似文献

Objective: The objectives of this article are first to give an overview of the risks of bias in trial-based economic evaluations and, second, to identify how key sources for bias can be revealed and overcome (i.e. what bias-reducing strategies might be employed) in future trial-based economic evaluations in the field of health psychology.

Design: Narrative review discussing sources of bias in trial-based economic evaluations and bias-reducing strategies.

Results: We identified 11 biases and assigned them to a particular trial phase. A distinction is made between pre-trial biases, biases during the trial and biases that are relevant after the actual trial. All potential forms of bias are discussed in detail and strategies are shown to detect and overcome these biases.

Conclusion: In order to avoid bias in trial-based economic evaluations, one has to be aware of all the possible forms of bias. All stakeholders have to examine trial-based economic evaluations in a rigorous and stringent manner. This article can be helpful in this examination as it gives an overview of the possible biases which researchers should take into account.  相似文献

Repetition priming is a prominent example of non‐declarative memory, and it increases the accuracy and speed of responses to repeatedly processed stimuli. Major long‐hold memory theories posit that repetition priming results from facilitation within perceptual and conceptual networks for stimulus recognition and categorization. Stimuli can also be bound to particular responses, and it has recently been suggested that this rapid response learning, not network facilitation, provides a sound theory of priming of object recognition. Here, we addressed the relevance of network facilitation and rapid response learning for priming of person recognition with a view to advance general theories of priming. In four experiments, participants performed conceptual decisions like occupation or nationality judgments for famous faces. The magnitude of rapid response learning varied across experiments, and rapid response learning co‐occurred and interacted with facilitation in perceptual and conceptual networks. These findings indicate that rapid response learning and facilitation in perceptual and conceptual networks are complementary rather than competing theories of priming. Thus, future memory theories need to incorporate both rapid response learning and network facilitation as individual facets of priming.  相似文献

In psychotherapy, clients and therapists work together to forge a path towards better mental health. Key to this process is genuine and honest communication. However, much previous research suggests that clients are not always fully truthful with their therapists. In this study, we make a preliminary examination of the relationship between client deception in therapy, the quality of the therapeutic relationship and therapeutic outcomes.  相似文献

Information overload (IO) indicates the exchange of too much low-quality information in virtual teams. When being overloaded with information, teams need to adapt and to change communication behaviour. This study introduces and tests a structured online team adaptation (STROTA) procedure that enables virtual teams to reduce IO by improving their team mental model quality. STROTA, built from team adaptation models, is a moderated intervention consisting of three stages: (1) individual situation awareness, (2) team situation awareness, and (3) plan formulation. STROTA was tested in the context of an experimental problem-solving task. Participants (N = 363) worked in virtual teams of three and were randomly assigned to one of four experimental conditions: no STROTA, incomplete STROTA (step 1, steps 1–2), and complete STROTA (steps 1–2–3). We found teams that followed a complete STROTA procedure experienced lessened IO over time. Teams with complete STROTA showed the largest development of TMM immediately after STROTA. Finally, multilevel mediation analyses showed that TMM are mediators that explain the influence of STROTA on IO.  相似文献

Long-term potentiation (LTP) at input synapses to the lateral nucleus of the amygdala (LA) is a candidate mechanism for memory storage during fear learning. Cellular mechanisms of LTP have been nearly exclusively investigated in coronal brain slices. In our experiments, we used a horizontal brain slice preparation of rats that preserved most of the connections to cortical areas and the hippocampus. The stimulation electrodes were located either within the external capsule (EC) or the LA. The aim of the present study was to investigate the mechanisms of LTP induced either by weak theta burst stimulation (TBS) or strong high frequency stimulation (HFS) using the two different stimulation sites. Whereas both TBS and HFS of afferences running through the LA induced stable LTP, TBS failed to induce LTP of EC-inputs to the LA. The present findings also show that LTP in the LA exhibits vulnerability at different time windows after induction. The time window was dependent on the kind of stimulated afferences. Later LTP becomes resistant to disruption by low frequency stimulation. We could show that both used inputs depended on NMDA receptors for LTP-induction. LTP induced by stimulation of fibers within the LA was not altered by nifedipine (10 microM). In contrast, EC-induced LTP was dependent on L-type voltage-gated calcium channels (VGCC). Finally, we found a higher magnitude of LTP in females using TBS, whereas HFS did not cause gender-specific differences. Our study supports the conclusion that the form of LA-LTP depend on which afferences are activated and what pattern of stimulation is used to induce LTP.  相似文献

The current study examined the individual and joint effects of the Big Five personality traits and acculturation on coping styles. Using the proposed framework of McCrae ( 22 2001), the relations among these variables were evaluated at the intracultural level to exploit previously unexplored within‐culture variability for an unstudied Asian American group (Korean Americans). This approach emphasizes the unique expression of specific personality traits in a single culture. A community sample of Korean Americans completed measures of the Five‐Factor Model of Personality (NEO‐PI‐R; Costa & McCrae, 13 1992), coping (Brief COPE; Carver, 7 1997), and acculturation (SL‐ASIA; Suinn, Ahuna, & Khoo, 40 1992). The results primarily showed statistically significant relations between the Big Five personality traits and coping. Neuroticism was positively related to indices of emotion‐focused coping (emotional support) and avoidance (substance abuse, behavioural disengagement, venting, self‐blame); Extraversion, Conscientiousness, and Openness were positively related to indices of problem‐focused (active coping, planning) and emotion‐focused coping (positive reframing, humour, acceptance); and Agreeableness was positively associated with active coping and humour. Acculturation was only significantly (and positively) associated with venting. Significant Acculturation×Big Five personality traits interactions were found, however. For individuals high in acculturation, both Neuroticism and Openness were positively related to indices of avoidance coping. Moreover, for individuals low in acculturation, a negative relationship was found between Conscientiousness and venting. These results show that there is considerable within‐culture variation for the dimensions of the Five‐Factor Model of Personality, coping styles, and acculturation in this largely bicultural sample. Moreover, the amount of variation and its directionality among the target study variables is similar to that typically found in Caucasian American samples. Finally, the stronger relations found between the dimensions of personality and coping styles (relative to the relations found between acculturation and coping styles) suggests that personality traits rather than acculturation may be more important clinically when profiling patients and developing treatment plans.  相似文献

For humans and monkeys, understanding the actions of others is central to survival. Here we review the physiological properties of three cortical areas involved in this capacity: the STS, PF and F5. Based on the anatomical connections of these areas, and the Hebbian learning rule, we propose a simple but powerful account of how the monkey brain can learn to understand the actions of others by associating them with self-produced actions, at the same time discriminating its own actions from those of others. As this system appears also to exist in man, this network model can provide a framework for understanding human social perception.  相似文献
