It is well established that the importance assigned to a trauma can affect one's recovery and psychological health in numerous ways. Event centrality is an increasingly popular construct that captures the tendency among survivors to reevaluate and possibly accommodate their worldviews posttrauma. The centrality given to trauma appears to serve as a “double-edged sword” in that this construct might factor prominently in both posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). Focusing on 257 violence-exposed teachers from educational departments throughout El Salvador, we examined whether the centrality assigned by the teachers to stressful life events uniquely predicted both PTSD symptomatology and PTG. Results revealed that event centrality was positively related to both PTSD and PTG, even when controlling for demographic factors, violence exposure, and depression. In addition, PTSD symptomatology and PTG were not associated with one another in this sample. In summary, these findings support the role of event centrality as a contributing factor for PTSD and PTG among persons exposed to pervasive trauma. 相似文献

The sequential microstructure evolution of abnormal grain growth (AGG) in the aluminium alloy (AA5052) was investigated to analyse the migration behaviour of coincidence site lattice (CSL) boundaries, which are known to play an important role in inducing AGG. The sequential evolution showed that CSL boundaries tend to disappear more slowly than general boundaries at the growth front of abnormally growing grains. Especially, the migration rate of Σ9 boundaries was noticeably low, which is contrary to the previous suggestions. 相似文献

The effects of cementite morphology on short-fatigue-crack propagation were investigated by subjecting smooth steel specimens to rotating-bending fatigue tests. Intergranular and transgranular cementite precipitation steels free of other phases were prepared through heat treatments. In the intergranular cementite precipitation steel, short-fatigue-crack propagation was decelerated at the grain boundaries, and accelerated in the grain interiors. In contrast, the transgranular precipitation steel showed the deceleration of the crack propagation in the grain interiors but not in the vicinity of the grain boundaries. 相似文献

Suicide and suicidal ideation are serious public health concerns. Accurate detection and assessment are critical first steps in addressing this challenging issue. The present study examined self-reported suicidal ideation in a sample of United States Air Force enlisted active duty basic trainees (N = 470) using the Multidimensional Suicide Inventory (MSI-28). Exploratory factor analyses revealed a 4-factor structure for the MSI-28 in this sample. Together, these 4 factors explained approximately 72% of the variance in the MSI-28. The MSI-28 evidenced moderate to strong associations with measures of resilience (Dispositional Resilience Scale-15; DRS-15) and psychological distress (Outcome Questionnaire; OQ-30.2). These findings demonstrate that the MSI-28 is a promising tool for clinical measurement of self-reported suicidality. Future directions for further validation of the MSI-28 are discussed. 相似文献

Posttraumatic growth (PTG) and psychopathology are common outcomes following exposure to adversity and trauma. We examined the relationship of PTG to posttraumatic stress disorder (PTSD) and depression in a group of young Iraqi students with war trauma exposure. These young Iraqis had experienced an average of 13 different war‐related adversities. The prevalence of probable PTSD was 17.2% and probable depression 23.1%. PTSD was associated with higher and depression with lower PTG. In addition, the relationship between PTG and PTSD was stronger among males than females. Although PTSD and depression were relatively common, they were related to PTG in opposite directions. 相似文献

We examine the dynamics of substance use and psychiatric symptoms from childhood to adolescence using a longitudinal study of Mexican-origin families (N = 674). We present a longitudinal model capturing the trajectories of substance use and psychiatric symptoms (depression, conduct disorder), as well as the interrelations between these trajectories over time. Such a model is an extension of latent change score models designed to account for the occurrence of psychiatric symptoms while also accommodating a large amount of zeros for nonoccurrence and characterizing the changes over time in the count data. We compare this model with a more traditional approach based on a log transformation of the data. We describe differences between these approaches and highlight the benefits of using the two-part model when the data include a large amount of zeros for nonoccurrence of the behavior. 相似文献

Reingold, Reichle, Glaholt, and Sheridan (2012) reported a gaze‐contingent eye‐movement experiment in which survival‐curve analyses were used to examine the effects of word frequency, the availability of parafoveal preview, and initial fixation location on the time course of lexical processing. The key results of these analyses suggest that lexical processing begins very rapidly (after approximately 120 ms) and is supported by substantial parafoveal processing (more than 100 ms). Because it is not immediately obvious that these results are congruent with the theoretical assumption that words are processed and identified in a strictly serial manner, we attempted to simulate the experiment using the E‐Z Reader model of eye‐movement control (Reichle, 2011). These simulations were largely consistent with the empirical results, suggesting that parafoveal processing does play an important functional role by allowing lexical processing to occur rapidly enough to mediate direct control over when the eyes move during reading. 相似文献

For many who experience serious mental illness, spirituality and religion can be common vehicles that provide a sense of coherence and meaning to life. However, in the presence of early trauma, spiritual and religious beliefs may be enhanced or destroyed, or never develop. This paper explores the relationship between spirituality/religion, early trauma, and serious mental illness. Three case examples from a qualitative phenomenological study are presented to illustrate spiritual and religious struggles that can arise and how a person can work through these over time to use spirituality and religion as positive resources for recovery. Tentative implications for practice are offered. 相似文献
