What constitutes traffic event severity in terms of human danger perception?

This study focuses on the severity gradation of non-collision events. Earlier theoretical work has suggested that a proper severity measure for an event should reflect the risk of personal injury, which is often split into two components, including the risk of a collision and the potential consequences had the collision taken place. While a great number of severity measures have been suggested, most of them fail to address both components, thus resulting in counter-intuitive event gradations and inconclusive outcomes in validation studies. Conversely, it has been shown that human observers often show very good agreement when given a task to rank traffic situations by their severity or level of danger. The aim of this study is to investigate in depth how human judgements of the severity of traffic situations can be expressed by means of objective safety indicators. In this study, a set of video-recorded traffic situations, in which a cyclist passes straight through an intersection while a left or right-turning motor vehicle crosses the cyclist’s path, were analysed. Binary logistic regression was used to develop models assessing the most important traffic severity indicators associated with human feelings of danger. The results showed that the initial conditions of a traffic event, defined as a start of an evasive action, contain the most important information for explaining its severity. Moreover, variables related to both proximity and collision consequences are important and should be integrated into severity measures.     

Understanding the immediate aftereffects of road traffic crashes in Argentina: The role of injury

The current paper reports a field study of 132 Argentinian individuals who experienced a road traffic crash (RTC), focusing on the role of physical injury in the early aftermath of the crash. Three groups of participants were studied: 1) individuals who were <1 month post-RTC who were not injured (<1 mo, Not Injured, n = 89), 2) individuals who were <1 month post-RTC who were injured (<1 mo, Injured, n = 15), and 3) individuals who were 1–3 months post-RTC who were injured (1–3 mo, Injured, n = 28). Examination of PTSD symptoms indicated that with several exceptions, most PTSD symptoms were endorsed at higher levels by the two injured groups, relative to the not injured group. Consideration of post-RTC cognitive and interpersonal factors indicated that the two injured groups reported lower self-efficacy and higher levels of rumination, relative to the Not Injured group. Additionally, the 1–3 mo Injured group reported being more socially isolated, relative to the two other groups. Results are discussed in light of related literature, with elaboration of potential public health interventions designed to target injured survivors of RTCs.     

Profils d’apprenti·e·s reflétant des tensions de rôle en formation professionnelle en alternance en Suisse

Role stress among apprentices are a key element in defining the quality of dual vocational education and training. However, few studies have examined the perceptions and importance of role tensions in this particular context. Accordingly, this contribution focuses on the role stress perceived by dual apprentices through a questionnaire survey. Latent profile analyses allowed to distinguish four apprentices’ profiles in terms of perceptions of role stress, ranging from minimal to prominent role stress. Differences in socio-demographic characteristics, motivation for choosing the training, professional identification, and intention to terminate the apprenticeship contract were also identified. The study provides information on the importance of considering apprentices as a heterogeneous population in terms of role stress, but also on the different motivational and identity issues associated with the profiles. Discussing such issues would also improve the learning experience.     

The Driving Behavior Survey as a Measure of Behavioral Stress Responses to MVA-Related PTSD

Numerous treatments are available that address the core symptoms of posttraumatic stress disorder (PTSD). However, there are a number of related behavioral stress responses that are not assessed with PTSD measures, yet these behavioral stress responses affect quality of life. The goal of the current study was to investigate whether a recently developed measure of behavioral stress response, the Driving Behavior Survey (DBS), was sensitive to change associated with treatment among a group of participants diagnosed with PTSD. The DBS indexes anxious driving behavior, which is frequently observed among individuals with motor vehicle accident-related PTSD. Participants (n = 40) were racially diverse adults (M age = 40.78, 63% women) who met diagnostic criteria for motor vehicle accident-related PTSD. Hierarchical linear modeling analyses indicated that participants who were assigned to a brief, exposure-based intervention displayed significant reductions on the DBS subscales relative to participants assigned to the wait-list control condition (r = .41–.43). Moreover, mediational analyses indicated that the observed reductions on the DBS subscales were not better accounted for by reductions in PTSD. Taken together, these findings suggest that the DBS subscales are sensitive to changes associated with PTSD treatment and can be used to augment outcome assessment in PTSD treatment trials.     

Attention Bias for Threatening Information in Children Following a Distressing Medical Procedure

Attention bias is common in adults with post‐traumatic stress disorder (PTSD) but is less studied in children. Children (n = 22) who experienced a potentially distressing procedure in an outpatient clinic (removal of K‐wires from orthopaedic fractures) and a group of medically unwell children (illness group; n = 27) were compared with healthy controls (n = 32). Children's baseline level of PTS symptoms were indexed prior to the medical procedure, and again at 1‐week follow‐up. Immediately after the K‐wire removal, children completed a dot probe task using two categories of target words (medical threatening and emotionally threatening). While K‐wire children showed an overall bias away from negative words relative to healthy controls, the illness group did not significantly differ from healthy controls. Attention bias in K‐wire and illness groups was unrelated to later PTS symptoms.     

Family income,parental education and internalizing and externalizing psychopathology among 2–3‐year‐old Chinese children: The mediator effect of parent–child conflict

Using a sample of 156 Chinese children aged 2–3 years and their parents, this study examined the effects of socio‐economic status, specifically family income and parental education, on the children's internalizing and externalizing psychopathology and whether these effects were mediated by mother–child and father–child conflict. Results indicated that family income, maternal education and paternal education all negatively predicted externalizing symptoms. Income also negatively predicted internalizing symptoms among boys but not girls. Maternal education negatively predicted internalizing symptoms among girls but not boys. The effects of income on psychopathology were fully mediated by mother–child and father–child conflict. In contrast, the effects of education were not mediated or only partially mediated by conflict. Findings are discussed in the framework of the family stress model.     

Trajectories of Posttraumatic Stress Among Urban Residents

Urban residents experience a wide range of traumatic events and are at increased risk of assaultive violence. Although previous research has examined trajectories of posttraumatic stress (PTS) through latent class growth analysis (LCGA) among persons exposed to the same index events (e.g., a natural disaster), PTS trajectories have not been documented among urban residents. The aims of this study were to conduct LGCA with a sample of trauma survivors from Detroit, Michigan (N = 981), and to explore predictors of trajectory membership. Participants completed three annual telephone surveys, each of which included the posttraumatic stress disorder (PTSD) Checklist-Civilian Version. Four PTS trajectories were detected. Although the majority evidenced a trajectory of consistently few symptoms (Low: 72.5 %), 4.6 % were in a trajectory of chronic severe PTSD (High), and the remainder were in trajectories of consistently elevated, but generally subclinical, levels of PTS (Decreasing: 12.3 %; Increasing: 10.6 %). Socioeconomic disadvantage (e.g., lower income), more extensive trauma history (e.g., childhood abuse), and fewer social resources (e.g., lower social support) were associated with membership in higher PTS trajectories, relative to the Low trajectory. The results suggest that efforts to reduce PTS in urban areas need to attend to socioeconomic vulnerabilities in addition to trauma history and risk for ongoing trauma exposure.     

Paternal influences on infant temperament: Effects of father internalizing problems,parenting-related stress,and temperament

Temperament ratings were obtained from 98 fathers when their infants were 4 and 6 months of age to examine effects of paternal characteristics on infant temperament. Parental stress, internalizing symptoms, and father's temperament were considered as factors possibly contributing to differences in their child's temperament.     

Prospective relations among preschoolers' play,coping, and adjustment as moderated by stressful events

This study evaluated the prospective contribution of preschoolers' pretend play to observer reports of internalizing and externalizing behavior problems one year later, as mediated by observed coping flexibility during a delay of gratification task and as moderated by children's exposure to stressful life events. Preschoolers' (N = 250; M_age = 49.05 months, SD = 2.95; 50% female) fantasy and affect expression in pretend play were assessed during a laboratory visit. Moderated mediation models tested for conditional indirect effects of play fantasy and affect expression on behavior problems through coping flexibility as a function of the child's exposure to stress. Preschoolers' fantasy and negative affect expression in pretend play predicted lower rates of internalizing, but not externalizing, problems. Coping flexibility partially mediated this relation, particularly among children with relatively more life stress. These findings clarify processes by which, and contexts within which, preschoolers' pretend play influences later behavioral adjustment.
