Self-worth as a mediator between attachment and posttraumatic stress in interpersonal trauma

It is well documented that most trauma survivors recover from adversity and only a number of them go on to develop posttraumatic stress disorder (PTSD). In addition, survivors of interpersonal trauma (IPT) appear to be at heightened risk for developing PTSD in comparison to survivors of noninterpersonal trauma (NIPT). Despite a robust association between IPT exposure and attachment disruptions, there is a dearth of research examining the role of attachment-related processes implicated in predicting PTSD. Using a sample of college undergraduates exposed to IPT and NIPT, this study explores the mediating effect of self-worth in the relationship between attachment and PTSD. It is hypothesized that insecure attachment will be related to posttraumatic symptomatology via a reduced sense of self-worth in IPT survivors but not in NIPT survivors. Mediation analyses provide support for this hypothesis, suggesting the importance of considering negative cognitions about the self in therapeutic interventions, particularly those offered to IPT survivors.     

Anticipated Mortality,HIV Vulnerability,and Psychological Distress Among Adolescents and Young Adults at Higher and Lower Risk for HIV Infection

This study described multivariate patterns of associations among psychological distress, anticipated mortality, and perceived vulnerability to HIV among urban, multiethnic samples of (a) adolescents (N = 120) undergoing substance abuse treatment, and (b) young adult university students (N = 222). While there were significant correlations between (a) psychological distress and reported vulnerability to HIV in the treatment sample; and (b) psychological distress and anticipated mortality in the university sample, there was no significant relation between anticipated mortality and perceived vulnerability to HIV in either sample. Cluster analysis revealed four distinct and meaningful groups in both samples, including parallel high- and low-functioning subgroups. Multivariate group differences in both samples were validated via corresponding group differences in (a) motives for drinking during sex, and (b) markers of serious psychological distress (e.g., suicidal thoughts and attempts). The findings challenge popular sterotpes of adolescents' perceptions of their own mortality and vulnerability to HIV and may have significant implications for the planning and implementation of effective HIV preventions among at-risk youth.     

Traumatic Events and Maternal Education as Predictors of Verbal Ability for Preschool Children Exposed to Intimate Partner Violence (IPV)

Despite research on the effects of intimate partner violence (IPV) on children, little is known about its impact on cognitive development. In this study, 87 preschool-aged children and their mothers exposed to IPV within the last two years participated in interviews to ascertain verbal ability, history of violence, and exposure to trauma. When compared to a national sample of 1,700 same-age children not evaluated for exposure to traumatic events, children exposed to IPV scored significantly lower on verbal ability, as assessed with standardized measures. In order to understand variation in verbal ability, multiple regression models were tested. Both prior exposure to traumatic events and the level of mother’s education were significant predictors of verbal ability. However, level of education mediated the relationship between traumatic events and the child’s verbal ability.     

Maturité organisationnelle des organisations publiques et management des connaissances

Mass retirements from the public service and non‐renewal of roughly half the workforce create challenges both for the intergenerational transfer of knowledge and knowledge management more generally. This article reviews the literature on organizational learning, learning organizations and intelligent organizations, concluding that these concepts are not well linked together. It reports on findings from interviews with 50 executives from the Quebec public service, which create a portrait of knowledge management and transfer practices and how they could be improved. The article then develops a model of organizational maturity in five phases, based on these findings, linking the concepts of organizational learning, learning organizations and intelligent organizations.     

Ethnicity and risk for symptoms of posttraumatic stress following intimate partner violence: prevalence and predictors in European American and African American women

The present study uses a feminist theoretical framework to explore risk factors for the development of posttraumatic stress symptoms following intimate partner violence, with a community sample of 120 low-income European American and African American women. Hierarchical regression analyses were used to examine demographic, violence, and mental health variables that predict posttraumatic stress symptoms. The data reveal that African American women report lower levels of posttraumatic stress symptoms than do their European American peers. This difference was observed despite the presence of more empirically identified risk factors for African American women. Regression analyses show that symptoms of depression increase risk for posttraumatic stress for both groups. However, a difference was observed such that past victimization increase risk for only European American women, whereas amount of psychological violence in the previous year increases risk for only African American women. Potential explanations for observed ethnic differences are offered.     

The Dynamic Nature of Justice: Influential Effects of Time and Work Outcomes on Long-Term Perceptions of Justice

Competing hypotheses are used to test whether justice perceptions change over time, and if so, whether the changes become more polarized over time (more positive or negative) or whether the changes fluctuate over time based on subsequent work outcomes. Results suggest there is no polarizing or fluctuating effect in perceptions of interpersonal justice over time and no polarizing effect in perceptions of procedural justice for individuals with high initial perceptions of procedural justice. However, individuals with low initial perceptions of procedural justice increased procedural justice perceptions over time, resulting in a polarizing effect in the opposite direction of the prediction. Hierarchical regression analysis indicates initial perceptions of procedural justice tend to fluctuate over time due to intervening work decision outcomes, although in the opposite direction of what was predicted.
