In the present study, we investigated the phenomenological characteristics of distant trauma memories and the relationship between the vividness of trauma memories, the centrality of event and symptoms of posttraumatic stress in two groups with different types of trauma exposure, namely survivors and bereaved, from the fire on the passenger ferry, Scandinavian Star, 26 years earlier. More than two decades after the fire, the traumatic event was represented as a vivid, emotional recollection for many of the victims. For both the survivors and the bereaved, a higher degree of vividness of trauma memories and centrality of the event were associated with higher levels of posttraumatic stress. The present findings show that even very distant trauma memories can be represented as vivid recollections. Furthermore, the findings suggest that both vividness of trauma memories and event centrality may contribute to explain how posttraumatic stress reactions can remain present over a very long time.  相似文献

We examined trajectories of academic and social functioning in children with attention-deficit/hyperactivity disorder (ADHD) to identify those who might be at risk for especially severe levels of academic and social impairment over time. We estimated a series of growth mixture models using data from two subsamples of children participating in the NIMH Collaborative Multisite Multimodal Treatment Study of Children with ADHD (MTA) including those with at least baseline and 96-month data for reading and mathematics achievement (n = 392; 77.3% male; M age = 7.7; SD = 0.8) or social skills ratings from teachers (n = 259; 74.9% male; M age = 7.6; SD = 0.8). We compared latent trajectories for children with ADHD to mean observed trajectories obtained from a local normative (i.e., non-ADHD) comparison group (n = 289; 80.6% male; M age = 9.9; SD = 1.1). Results indicated six latent trajectory classes for reading and mathematics and four classes for teacher social skills ratings. There was not only a relationship between trajectories of inattention symptoms and academic impairment, but also a similarly strong association between trajectory classes of hyperactive-impulsive symptoms and achievement. Trajectory class membership correlated with socio-demographic and diagnostic characteristics, inattention and hyperactive-impulsive symptom trajectories, externalizing behavior in school, and treatment receipt and dosage. Although children with ADHD display substantial heterogeneity in their reading, math, and social skills growth trajectories, those with behavioral and socio-demographic disadvantages are especially likely to display severe levels of academic and social impairment over time. Evidence-based early screening and intervention that directly address academic and social impairments in elementary school-aged children with ADHD are warranted. The ClinicalTrials.gov identifier is NCT00000388.  相似文献

Biomedical research policy in recent years has often tried to make such research more ‘translational’, aiming to facilitate the transfer of insights from research and development (R&D) to health care for the benefit of future users. Involving patients in deliberations about and design of biomedical research may increase the quality of R&D and of resulting innovations and thus contribute to translation. However, patient involvement in biomedical research is not an easy feat. This paper discusses the development of a method for involving patients in (translational) biomedical research aiming to address its main challenges.After reviewing the potential challenges of patient involvement, we formulate three requirements for any method to meaningfully involve patients in (translational) biomedical research. It should enable patients (1) to put forward their experiential knowledge, (2) to develop a rich view of what an envisioned innovation might look like and do, and (3) to connect their experiential knowledge with the envisioned innovation. We then describe how we developed the card-based discussion method ‘Voice of patients’, and discuss to what extent the method, when used in four focus groups, satisfied these requirements. We conclude that the method is quite successful in mobilising patients’ experiential knowledge, in stimulating their imaginaries of the innovation under discussion and to some extent also in connecting these two. More work is needed to translate patients’ considerations into recommendations relevant to researchers’ activities. It also seems wise to broaden the audience for patients’ considerations to other actors working on a specific innovation.  相似文献

Epidemiologic, prospective, and retrospective research confirms that family relational variables are significant risk factors for the development of mental and physical health problems in children as well as adults. In addition, relationships also play a moderating role in the maintenance, exacerbation, or amelioration of chronic health problems. Although acknowledgment of the importance of these variables in the pathophysiology of a number of health conditions is reaching more prominence, the integration of assessments of family factors as part of standard health care has made little progress. With the arrival of the Affordable Care Act in the United States, there is a desire for earlier identification of these risk factors, and the ability to implement prevention programs that reduce risk, and enhance protective factors. On a global level, there is increased awareness of the health impact of relational problems, for example, many countries have attempted to implement programs to decrease domestic violence. More reliable and standardized assessments of key relational processes will enhance both of these missions, and allow comparison of a variety of prevention and intervention programs. This article discusses progress over the last decade in constructing more reliable definitions of relationship processes, how these have been integrated into the Diagnostic and Statistical Manual 5th edition (DSM‐5), and progress toward implementation into the World Health Organization's International Classification of Diseases (ICD‐11).  相似文献

In newly formed groups, informal hierarchies emerge automatically and readily. In this study, we argue that emergent group hierarchies enhance group performance (Hypothesis 1) and we assume that the more the power hierarchy within a group corresponds to the task‐competence differences of the individual group members, the better the group performs (Hypothesis 2). Twelve three‐person groups and 28 four‐person groups were investigated while solving the Winter Survival Task. Results show that emerging power hierarchies positively impact group performance but the alignment between task‐competence and power hierarchy did not affect group performance. Thus, emergent power hierarchies are beneficial for group performance and although they were on average created around individual group members' competence, this correspondence was not a prerequisite for better group performance.  相似文献

Construing a traumatic event as central to one's life story and identity is associated with posttraumatic stress. The longitudinal relationship between centrality of event and trajectories of posttraumatic stress was examined. Data from ministerial employees were collected 10 months, 2 years, and 3 years after the 2011 Oslo bombing (N = 259). Using structural equation modeling, the launch and the snare hypotheses were tested. Support for the launch hypothesis was found; higher levels of event centrality 10 months after the attack were associated with higher levels of posttraumatic stress across time. Support for the snare hypothesis was also found; higher levels of centrality 10 months and 2 years after the bombing were related to higher levels of posttraumatic stress, beyond what could be anticipated based on the individual's general trajectory. This suggests that event centrality can influence the overall trajectory, and may also have additional time‐specific effects on posttraumatic stress.Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

In this longitudinal study, 70 children were observed during 90 min of free play in their child care centres at 15 and 23 months of age. The children (39 boys and 31 girls) attended 51 different care groups in 39 centres. The occurrence and stability of peer interactions in the second year of life and their relations to children's socio-emotional adjustment were examined. The frequency of children's negative initiatives towards peers showed significant inter-individual stability from 15 to 23 months and predicted child aggressive/disruptive behaviour at 23 months as rated by professional caregivers in child care. Involvement in positive interactions with peers, and particularly positive responses to peer behaviours at 15 months, predicted well-being in child care at 23 months as rated by professional caregivers. The frequency of negative initiatives towards peers significantly increased and the frequency of positive responses to peer behaviours significantly decreased from 15 to 23 months.  相似文献
