Early trauma and serious mental illness: what role does spirituality play?

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.     

Narratives of trauma,recovery, and growth: The complex role of sport following permanent acquired disability

ObjectivesThe purpose of this study was to explore how participation in sport may assist an individual in working through experiences of physical trauma.DesignAn instrumental, collective case study was used to illustrate the experiences of two men with acquired disabilities.MethodBoth men participated in sport at a high level and suggested that participation was a central feature of their recovery from trauma. Interviews invited participants to describe their lives pre-trauma, the trauma experience, and the recovery process. A narrative analysis was used to focus on the progression of the plot outlined in each participant's story.ResultsOur results exemplify two narrative types: assimilation and positive accommodation. The narrative of positive accommodation demonstrates how sport provided mastery experiences, enhanced relationships, corporeal understanding and enhanced life philosophies. The alternative narrative of assimilation was associated with resilience to trauma. Our case illustrates that such a narrative may be focused on re-capturing previous life meanings and creating an athletic identity using past definitions of sport.ConclusionWhile the narrative of positive accommodation is most frequently associated with posttraumatic growth, our case outlines the occurrence of synchronous positive and negative experiences, even within the same dimensions of growth. The narrative of assimilation demonstrates the challenges presented by the rehabilitation and sporting environments for an individual who aimed to restore their pre-trauma self and pre-trauma beliefs.     

A Comparison of Posttraumatic Growth After Acquired Brain Injury or Myocardial Infarction

Posttraumatic growth (PTG) is known to occur following acquired brain injury (ABI). It is not yet known to what extent PTG experiences following ABI are unique to the neurological nature of the injury. We investigated PTG in survivors of ABI or myocardial infarction (MI); MI is comparable to ABI but does not have a primary neurological element. Thirty-three ABI survivors (age M = 51.6, SD = 12.4; 52% male; years since injury M = 5.5, SD = 5.3) and 47 MI survivors (age M = 66.4, SD = 9.9; 79% male, years since injury M = 9.9, SD = 8.6) completed a survey including the Posttraumatic Growth Inventory (PTGI). Unadjusted analyses showed no significant group differences on PTGI total score (ABI M = 54.0, SD = 19.6; MI M = 54.6, SD = 23.6; d = .03, p = .902) or on any of the five subscales, but analyses adjusted for covariates showed that scores on “Relating to others” were higher in participants with ABI (unstandardized coefficient = 5.43; 95% CI .27, 10.60; p = .039). Open-ended comments revealed aspects of growth in both samples that were not directly captured by the five PTGI factors.     

An Examination of Disclosure,Mental Health Treatment use,and Posttraumatic Growth Among College Women Who Experienced Sexual Victimization

Few investigations have sought to identify factors associated with posttraumatic growth among survivors of sexual victimization. The present study examined the relationship between posttraumatic growth, disclosure, and mental health treatment use following sexual assault. Undergraduate female psychology students (N = 85), who reported a prior history of sexual victimization, completed measures assessing trauma exposure, posttraumatic growth, disclosure, and mental health treatment use. Results revealed that degree of disclosure of the assault to support sources and mental health treatment use following sexual assault was related to increased posttraumatic growth. Findings have valuable implications for treatment interventions for survivors of sexual trauma.     

Multiproblem Families Referred to Youth Mental Health: What's in a Name?

The purpose of this study was threefold, namely (1) to differentiate between multiproblem families and control families on characteristics and processes within the family based on a theoretical framework, (2) to identify multiproblem families by establishing cut‐off scores on various questionnaires, and (3) to categorize multiproblem families into subtypes by cluster analyses. Various questionnaires were administered to multiproblem families (n = 85) and control families (n = 150). Results showed that what we propose to refer to as multiproblem families present a broad range of problems on seven domains: (1) child factors, (2) parental factors, (3) childrearing problems (inadequate or inconsistent parenting), (4) family functioning problems, (5) contextual problems, (6) social network problems, and (7) mental health care problems. Further, reliable cut‐off scores were established for various questionnaires. Finally, three types of families were found: (1) community‐problem families, (2) multiproblem families, and (3) child‐focused mild‐problem families. This paper looks to advance an evidence‐based definition and assessment of “multiproblem families” suggesting the possible value of defining and assessing multiproblem families in relation to these seven dimensions. Moreover, the classification of multiproblem families stresses the importance of providing tailored treatments.     

Resilience in developing systems: the promise of integrated approaches

Abstract

This article describes a contemporary systems approach to resilience in human development and its promise for integrating findings and applications across system levels. Resilience is defined as the capacity of a system for successful adaptation to disturbances that threaten system function, viability, or development. Advantages of this definition are delineated in regard to integrating sciences and disciplines across scales and levels of interaction in a bioecological systems framework. Central concepts of resilience, including pathways and cascades, are described in light of this approach, and advances that link system levels are highlighted. Given significant progress toward a more dynamic, integrated, multisystem approach, developmental resilience science stands at new frontier of possibilities that promises to inform science, practice, and policy focused on building human capacity for surviving and thriving in times of turbulence and change.     

The safety performance of connected vehicles on slippery horizontal curves through enhancing truck drivers’ situational awareness: A driving simulator experiment

Although drivers can adequately adjust their operating speed according to the road curvature, they show a lack of recognition regarding the pavement friction conditions. In this regard, inappropriate speed selection on Horizontal Curves (HCs) with reduced surface friction can lead to a remarkable rate of run-off-road, sideswipe, head-on, and rollover crashes, especially on rural highways. Aligned with the Connected Vehicle (CV) Pilot Program on Interstate-80 in Wyoming, this study scrutinizes how CV advisory/warning messages can enhance traffic safety on slippery HCs. To this aim, a roadway consists of two HCs with regular and slippery pavement conditions was designed in a high-fidelity driving simulator experiment. A total of 24 professional truck drivers were recruited to drive the simulated roadway under CV and non-CV environments. In the CV scenario, drivers were informed about the pavement conditions and the advisory speeds before entering HCs. In contrast, no messages were given to non-CV drivers. Truck drivers' behaviors in both scenarios were quantified using four Kinematic-based Surrogate Measures of Safety (K-SMoS), including deviation from the pathway, instantaneous acceleration, lateral speed, and steering angle. CVs’ trajectories were statistically compared to non-CVs in terms of the central tendency and dispersion using the Wilcoxon Signed-Rank Test (WSRT) and Median Absolute Deviation (MAD), respectively. The results of WSRT depicted, under the effect of CV advisory/warning messages and throughout the slippery HC, the central tendency of four K-SMoS could be shifted toward zero by 23% up to 99%. This shifting is associated with a significant safety enhancement that potentially can reduce the likelihood of curve-related crashes on slippery HCs. It was revealed that the variation in drivers’ behavior on the slippery HC could be minimized in the CV environment, where 54% up to 95% reduction in the dispersions of four K-SMoS were observed, leading to more certainty in drivers’ behavior.     

Modeling the influence of mobile phone use distraction on pedestrian reaction times to green signals: A multilevel mixed-effects parametric survival model

Understanding and modeling the influence of mobile phone use on pedestrian behaviour is important for several safety and performance evaluations. Mobile phone use affects pedestrian perception of the surrounding traffic environment and reduces situation awareness. This study investigates the effect of distraction due to mobile phone use (i.e., visual and auditory) on pedestrian reaction time to the pedestrian signal. Traffic video data was collected from four crosswalks in Canada and China. A multilevel mixed-effects accelerated failure time (AFT) approach is used to model pedestrian reaction times, with random intercepts capturing the clustered-specific (countries) heterogeneity. Potential reaction time influencing factors were investigated, including pedestrian demographic attributes, distraction characteristics, and environment-related parameters. Results show that pedestrian reaction times were longer in Canada than in China under the non-distraction and distraction conditions. The auditory and visual distractions increase pedestrian reaction time by 67% and 50% on average, respectively. Pedestrian reactions were slower at road segment crosswalks compared to intersection crosswalks, at higher distraction durations, and for males aged over 40 compared to other pedestrians. Moreover, pedestrian reactions were faster at higher traffic awareness levels.     

Solidification thermal parameters,microstructural evolution and dendritic growth in an AlCuNi alloy

ABSTRACT

Unsteady-state upward solidification experiment was carried out with the Al-3Cu-3Ni (wt.%) alloy. Temperature profiles were obtained through a water-cooled directional solidification device. Analysis on the resulting as-cast microstructure and its adaptation to thermal solidification parameter, such as growth and cooling rates and solidification local time, V_L, T_R and t_SL, respectively, was carried out. The results showed that the resulting microstructure is constituted by an Al-rich primary phase (Al _α ), characterised by a dendritic network, and by second phases that take place within the interdendritic regions, forming a eutectic mixture composed by the β-Al₃Ni?+?θ-Al₂Cu intermetallic compounds (IMCs), whose size and morphology have been affected by V_L and T_R. The length of the microstructural scale of the Al _α phase was measured by the secondary dendritic spacing (λ ₂). The experimental mathematical expression of λ ₂ obtained in this work was compared with mathematical models proposed in the literature that associate t_SL-λ ₂ for non-equilibrium and equilibrium solidification conditions.
