Exploring patterns of personal growth initiative and posttraumatic stress: A latent profile analysis
Yuki Shigemoto Christine Robitschek 《Journal of American college health : J of ACH》2018,66(5):350-359
Objective: This study examined the inconsistent relationship found between personal growth initiative (PGI) and posttraumatic stress symptoms (PTSS) by exploring potential subgroups. In addition, after identifying the subgroups, potential predictors of these subgroups were examined. Participants: Participants were 534 undergraduate students who experienced a potentially traumatic event (PTE). Data collection occurred from March 2013 to December 2014. Methods: Because this was a preliminary study, archival data was used. Participants consisted of students who experienced a PTE within the past three years. Results: Latent profile analysis indicated a five-class model as the best-fitting model. Direct exposure and intentionality of the event were significant predictors of class membership; length of time since event and gender did not predict class membership. Conclusions: The current study provides a potential explanation of the inconsistent results between PGI and PTSS and also highlights the importance of acknowledging subgroups when utilizing PGI after a PTE. 相似文献

Traditional multiple hypothesis testing procedures fix an error rate and determine the corresponding rejection region. In 2002 Storey proposed a fixed rejection region procedure and showed numerically that it can gain more power than the fixed error rate procedure of Benjamini and Hochberg while controlling the same false discovery rate (FDR). In this paper it is proved that when the number of alternatives is small compared to the total number of hypotheses, Storey's method can be less powerful than that of Benjamini and Hochberg. Moreover, the two procedures are compared by setting them to produce the same FDR. The difference in power between Storey's procedure and that of Benjamini and Hochberg is near zero when the distance between the null and alternative distributions is large, but Benjamini and Hochberg's procedure becomes more powerful as the distance decreases. It is shown that modifying the Benjamini and Hochberg procedure to incorporate an estimate of the proportion of true null hypotheses as proposed by Black gives a procedure with superior power. 相似文献

Guided by the Common Ingroup Identity Model ( S. L. Gaertner & J. F. Dovidio, 2000 ) and Communication Accommodation Theory ( C. Shepard, H. Giles, & B. A. LePoire, 2001 ), we examined the role of identity accommodation, supportive communication, and self‐disclosure in predicting relational satisfaction, shared family identity, and group salience in multiracial/ethnic families. Additionally, we analyzed the association between group salience and relational outcomes as well as the moderating roles of multiracial/ethnic identity and marital status. Individuals who have parents from different racial/ethnic groups were invited to complete questionnaires on their family experiences. Participants (N = 139) answered questions about relationships with mothers, fathers, and grandparents. The results of the multilevel modeling analyses are discussed in terms of implications for understanding multiracial/ethnic families and family functioning. 相似文献

Whilst a small amount of research has been undertaken on peer violence in residential settings, very little is known about peer violence in foster care. This paper reviews the published research since 1995 about the nature and extent of peer violence in foster care and interventions for preventing and managing these negative peer interactions. The evidence indicates that young people in foster care can be the instigators and recipients of peer violence, but the limited number of studies found means that conclusions cannot be drawn about the extent of the problem. There is some evidence about the impact of this type of violence on young people and fostering households. However, there remain gaps in the evidence about the full extent of all forms of exploitation and violence that are experienced and instigated by young people in foster care, the circumstances in which it takes place, the young people affected and its co‐occurrence with other difficulties. Critically, young people's views were largely absent from included studies, an important area that requires further research. 相似文献

On the Road to Resilience: The Help‐Seeking Experiences of Irish Emigrant Survivors of Institutional Abuse 下载免费PDF全文
Understanding how survivors of complex trauma navigate towards resources can inform the design of interventions and health promotion strategies. However, there are little data on the resilience and help‐seeking experiences of this group or others who have experienced institutional abuse in childhood. This empirical study sets out to illustrate the help‐seeking experiences of Irish emigrant survivors of institutional childhood abuse (ICA). Twenty‐two survivors of ICA were purposefully recruited from community organisations in the UK and data were collected via semi‐structured interviews. As a result of negative initial help‐seeking experiences in Ireland, most participants engaged in long periods of self‐management and disclosed information about their childhood as part of a redress scheme in later life. Outside of this scheme, turning points, such as illness or family problems, and the needs of children were influential in seeking help. Peer support networks played an important role as a trusted signposting pathway towards formal interventions. Participants identified interpersonal barriers to formal help‐seeking as helping professionals' failure to share control, insensitivity to identity loss and literacy issues, and the lack of explicit boundaries. The paper concludes with a discussion about the implications for research and future practice.
‘This empirical study sets out to illustrate the help‐seeking experiences of Irish emigrant survivors of institutional childhood abuse’Key Practitioner Messages:
- Turning points, such as illness and bereavement, and the desire to provide for children, influence the help‐seeking of survivors of ICA.
- Irish emigrant survivors of ICA cite failure to share control, insensitivity to identity loss, literacy issues and the lack of explicit boundaries as barriers to help‐seeking.
- General awareness of ICA can help practitioners in low‐threshold services prevent against culturally insensitive practice.
- Peer support networks can provide uniquely trusted signposting towards formal interventions.

As social movements relying on the weak ties found in social networks have spread around the world, researchers have taken several approaches to understanding how networks function in such instances as the Arab Spring. While social scientists have primarily relied on survey or content analysis methodology, network scientists have used social network analysis. This research combines content analysis with the automated techniques of network analysis to determine the roles played by those using Twitter to communicate during the Turkish Gezi Park uprising. Based on a network analysis of nearly 2.4 million tweets and a content analysis of a subset of 5126 of those tweets, we found that information sharing was by far the most common use of the tweets and retweets, while tweets that indicated leadership of the movement constituted a small percentage of the overall number of tweets. Using automated techniques, we experimented with coded variables from content analysis to compute the most discriminative tokens and to predict values for each variable using only textual information. We achieved 0.61 precision on identifying types of shared information. Our results on detecting the position of user in the protest and purpose of the tweets achieved 0.42 and 0.33 precision, respectively, illustrating the necessity of user cooperation and the shortcomings of automated techniques. Based on annotated values of user tweets, we computed similarities between users considering their information production and consumption. User similarities are used to compute clusters of individuals with similar behaviors, and we interpreted average activities for those groups. 相似文献

A significant challenge in fitting metamodels of large-scale simulations with sufficient accuracy is in the computational time required for rigorous statistical validation. This paper addresses the statistical computation issues associated with the Bootstrap and modified PRESS statistic, which yield key metrics for error measurements in metamodelling validation. Experimentation is performed on different programming languages, namely, MATLAB, R, and Python, and implemented on different computing architectures including traditional multicore personal computers and high-power clusters with parallel computing capabilities. This study yields insight into the effect that programming languages and computing architecture have on the computational time for simulation metamodel validation. The experimentation is performed across two scenarios with varying complexity. 相似文献
