Systematic review of stress-related injury vulnerability in athletic and occupational contexts

Injury is a pervasive, expensive and, to some extent, preventable problem. Stress is a psychological risk factor for injury but little is known about how stress processes compare in athletic and occupational contexts. This paper reviews research on stress-related injury vulnerability in athletic and occupational contexts to characterize and compare samples, methods, and conclusions from the perspective of an integrated model of stress-related injury vulnerability. A comprehensive search of four major databases identified research in both athletic (n = 34) and occupational contexts (n = 22). Studies were coded to extract characteristics of the samples, research designs, measures, and conclusions about stress-injury relations. Studies used more prospective than cross-sectional or case control research designs. Injury was most frequently defined as missing one subsequent day of training or work (35.7%). Approximately 75% of the identified studies in each context indicated a positive association between stress and injury occurrence. The consistency of findings suggested a robust stress-related injury vulnerability for both exposures and responses, however, caution is warranted due to the diversity of measures and surveillance periods and the lack of experimental designs. New hypotheses are identified to refine models of stress-related injury vulnerability in athletic and occupational contexts.     

Travel and residual emotional well-being

This study addresses the question of how work commutes change positive versus negative and active versus passive mood experienced after the commutes. Analyses are presented for 230 time-sampled morning commutes to work, made by 146 randomly sampled people in three different Swedish cities, asking them to use smartphones to report mood before, directly after, and later in the work place after the commute. The results show that self-reported positive emotional responses evoked by critical incidents are related to mood changes directly after the commute but not later in the day. It is also shown that satisfaction with the commute, measured retrospectively, is related to travel mode, travel time, as well as both positive and negative emotional responses to critical incidents.     

Enriched housing reverses age-associated impairment of cognitive functions and tPA-dependent maturation of BDNF

Although tissue type plasminogen activator (tPA) and brain derived neurotrophic factor (BDNF) have been extensively described to influence brain outcomes in a number of disorders, their roles during physiological aging are poorly investigated. In the present study, we investigated whether maintenance of mice in different environmental conditions could influence age-associated changes in hippocampal tPA expression and BDNF maturation in relation with modifications of their cognitive performances. Our data indicate that maintenance in enriched housing led to a reversal of age-associated decrease in expression of hippocampal tPA. A subsequent increase in the level of mature BDNF and an improvement in emotional and spatial memories were observed. Taken together, these data suggest that the tPA–BDNF axis could play a critical role in the control of cognitive functions influenced both by the age and housing conditions.     

A meta-analysis of burnout with job demands, resources, and attitudes

A meta-analysis was conducted on job demands, resources, and attitudes and their relation with burnout in regard to the COR theory. The version of the Maslach Burnout Inventory used was explored as a moderator of the aforementioned variables. Results suggest that higher demands, lower resources, and lower adaptive organizational attitudes are associated with burnout. In particular, results of the current study show stronger relations than previous meta-analysis (Lee & Ashforth, 1996) have suggested. The scale type also provided some evidence of moderation, with stronger effects found in samples that utilized the MBI-HSS. Implications of the findings in relation to the COR theory and future research directions to clarify the relation between job demands, job resources, organizational attitudes and burnout are discussed.     

Attentional bias in post-traumatic stress disorder diminishes after symptom amelioration

Background

Avoidance and hypervigilance to reminders of a traumatic event are among the main characteristics of post-traumatic stress disorder (PTSD). Attentional bias toward aversive cues in PTSD has been hypothesized as being part of the dysfunction causing etiology and maintenance of PTSD. The aim of the present study was to investigate the cognitive strategy underlying attentional bias in PTSD and whether normal cognitive processing is restored after a treatment suppressing core PTSD symptoms.

Methods

Nineteen healthy controls were matched for age, sex and education to 19 PTSD patients. We used the emotional stroop and detection of target tasks, before and after an average of 4.1 sessions of eye movement desensitization and reprocessing (EMDR) therapy.

Results

We found that on both tasks, patients were slower than controls in responding in the presence of emotionally negative words compared to neutral ones. After symptoms removal, patients no longer had attentional bias, and responded similarly to controls.

Conclusion

These results support the existence of an attentional bias in PTSD patients due to a disengagement difficulty. There was also preliminary evidence that the disengagement was linked to PTSD symptomatology. It should be further explored whether attentional bias and PTSD involve common brain mechanisms.     

The effect of distance-dependent construals on schema-driven impression formation

Two experiments examine how distance-dependent construal can affect trait aggregation in impression formation. We propose that, because higher- versus lower-level construals promote the tendency to impose schematic structure on information processing, higher-level construals should enhance schema-driven trait aggregation. We test this by examining a classic impression formation phenomenon: the primacy effect (Asch, 1946). Increasing temporal distance (Study 1a) and priming higher-level construals (Study 1b) led participants to form more favorable impressions of targets described initially as intelligent versus envious. Decreasing temporal distance and priming lower-level construals, in contrast, reversed the primacy effect. Thus, the distance of a target, with its associated construal, can impact the aggregation of traits and consequently impacts people's evaluations of others.     

The limits of love: Predicting immediate versus sustained caring behaviors in close relationships

Do the same kinds of processes predict spontaneous acts of kindness and long-term caring behavior in relationships? Three studies examined predictors of immediate behaviors versus delayed, sustained behaviors. Positive feelings toward the relationship partner predicted pro-relational behaviors when the behaviors could be completed in an immediate and fairly short timespan, but not when the behaviors required performance after several days delay (Study 1) or when the behavior required continued self-regulation over a period of a week (Studies 2 and 3). Sustained behavior regulation was better predicted by factors related to self-regulation strength, such as trait conscientiousness, than it was by positive relationship feelings. However, when feelings were primed daily, the feelings-behavior link remained strong for sustained behaviors (Study 3). Together, these studies suggest that immediate pro-relational behaviors are more likely to be acts of the heart, whereas delayed, sustained pro-relational behaviors are more likely to be acts of will.     

Emotional difficulties in seventh grade children in Denmark

The present study investigates the prevalence of emotional difficulties and quality of life in a sample of 834 children from 56 seventh grade (aged 12-14 years) classes. Data was derived from a study of mental well-being developed by the National Council for Children, Denmark. The sample selection ensured that the children were nationally representative. Data was collected using the Strength and Difficulties Questionnaire (SDQ) and the Health Behaviour in School-aged Children (HBSC). Results indicated that 10.8% of children had concerns regarding emotional difficulties (6.6% definite concern; 4.2% some concern), and that significantly more girls than boys (44 girls and 10 boys) reported this concern. A novel finding was that emotional difficulties were related to children's perception of having low quality of life. Findings furthermore suggested that children's perception of a low home economy, less time spent on leisure activities, and female gender were all associated with emotional difficulties.
