Evaluating the impact of adaptive signal control technology on driver stress and behavior using real-world experimental data

While the operational and crash reduction benefits of adaptive signal control technology (ASCT) have long been investigated, the impact of this technology on driver behavior and stress is still uncertain. This study evaluated the impact of ASCT on driver behavior and stress in a real-world environment. Participants travelled through two arterial corridors, one equipped with ASCT and the other having traditional time-of-day coordinated signals. Driver stress was measured using a heart rate detector and a perceived stress scale while driver behavior was examined using vehicular trajectory data. Overall, driving behavior improved on the ASCT as compared to the non-ASCT corridor, as indicated by higher speeds and a fewer number of stops on the ASCT corridor relative to the non-ASCT corridor. Repeated measures ANOVA showed a statistically significant reduction in driver heart rate by −10 beats per minute over the ASCT corridor. A similar trend was observed for drivers’ perceived stress, analyzed by Wilcoxon sign ranked test. Driving behavior also showed significant improvement with ASCT presence, and speed was found to be negatively correlated with stress. Furthermore, the participants’ speed was controlled by the two systems i.e. ASCT and non-ASCT as expected. This study provides a significant proof of concept that ASCT can create positive improvements in driver stress and behavior that can be further investigated in the future.

Parenting Disruptive Preschoolers: Experiences of Mothers and Fathers

This study examined parental functioning and interactions with young children with Oppositional Defiant Disorder (ODD), with emphasis on differences between mothers and fathers in their responses to their child and in their unique contributions to the prediction of child disruptive behavior. Participants were 53 3- to 6-year olds with ODD who presented for treatment with two parents. Mothers reported more severe disruptive behavior and higher parenting stress than fathers. During parent-child interactions, mothers showed more responsiveness than fathers, even though children were more compliant during interactions with fathers. Regression analyses showed that fathers' parent-related stress was predictive of both mothers' and father's reports of disruptive child behavior; mothers' marital satisfaction was predictive of behavioral observations of child compliance with both mothers and fathers. This study revealed several important differences in the experiences of mothers versus fathers of disruptive children and indicates the importance of including the father in the child's assessment and treatment.     

The Use of the MMPI-2 Infrequency–Psychopathology Scale in the Assessment of Posttraumatic Stress Disorder in Male Veterans

This study evaluated the use of the F_P (Infrequency–Psychopathology) scale of the Minnesota Multiphasic Personality Inventory—2 (MMPI-2) as a measure of symptom overreporting among 423 service-seeking male veterans with and without PTSD. Results were consistent with several predictions based on the logic of the F_P scale. F_P produced lower scores for PTSD and non-PTSD patients than the other two MMPI-2 measures of infrequent responding; F and F_B. F_P also resulted in fewer invalid protocols than did F or F_B. Finally, F_P yielded lower correlations with MMPI-2 and other measures of psychopathology than did F or F_B. Consistent with previous studies, compensation-seeking status was associated with extreme elevations across clinical and validity scales. Contrary to previous findings, however, compensation-seeking veterans were also more likely to receive a PTSD diagnosis. Implications for the relationship between compensation seeking and symptom overreporting are discussed.     

Adjusting to job demands: The role of work self-determination and job control in predicting burnout

This study examined the dynamic interplay among job demands, job control, and work self-determination in order to predict burnout dimensions. A three-way interaction effect was found between job demands, job control and work self-determination in predicting each dimension of burnout (emotional exhaustion, depersonalization, and personal accomplishment). Overall, results showed that job control moderates the unhealthy effects of job demands in predicting emotional exhaustion and depersonalization only for employees with high levels of work self-determination. In addition, job control increases the relation between job demands and the sense of personal accomplishment only for employees with high levels of work self-determination. These results are discussed in light of the Job Demand-Control model.     

Overcoming a Legacy of Conflict: The Repercussive Effects of Stress and Intergenerational Transmission of Trauma Among Vietnamese Americans

The modern narrative of Vietnamese people is often strongly associated with events of the 20th century, such as the Vietnam War, but a legacy of strife in Southeast Asia spans many centuries. Enduring stress and trauma has pernicious psychological and physiological repercussions that have affected first and later generations of Vietnamese American refugees. To contextualize the present-day narrative, we review the history of Vietnam and the contemporary refugee experience in the United States. We then examine more proximal spheres of influence, including community and family. Finally, we review individual experiences of stress and trauma. We present recommendations to inform individual, group, family, and community-based counseling interventions, as well as recommendations for future research.     

Behavioural Problems in Children with Headache and Maternal Stress: Is Children's Attachment Security a Protective Factor?

Headache is a potentially disabling condition involving enduring pain that negatively influences the quality of family life. Behavioural problems are more common in children with headache and are potentially associated with higher levels of parental stress. The aim of this study was to evaluate the extent to which children's behavioural problems were associated with maternal stress and how the child's perception of security in the maternal attachment relationship moderates this association. Seventy‐one school‐aged children with headache (headache group (HG), age M = 9.8 years old, SD = 1.3) and 71 children from a low‐risk normative population (control group (CG), age M = 9.2 years old, SD = 1) and their mothers were involved in the study. Mothers' reports of children's behavioural problems were associated with higher maternal stress in the caring task both in the HG and in the CG. Results also showed that the HG was more at risk for behavioural problems, whereas no difference between groups was detected for parenting stress and for attachment insecurity. In children with headache, perception of attachment security decreased the strength of the association between maternal stress and externalizing behavioural problems. Secure attachment may provide children with headache and their parents with support in managing the negative emotions that arise in the context of significant health issues. Implications for practice are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Effects of occupational future time perspective on managing stressful work situations

According to the socioemotional selectivity theory (SST; Carstensen, 2006), older adults perceive their future time as increasingly limited, which motivates them to focus more on emotional goals and prefer passive emotion‐focused strategies. This study aims to investigate the effect of occupational future time perspective (OFTP) on the use of problem‐solving strategies in stressful work situations and to examine the effectiveness of these strategies on psychological well‐being. A sample of 199 Chinese clerical workers responded to a structured questionnaire on problem‐solving strategy use in relation to hypothetical work scenarios. Results revealed that relative to those with limited OFTP, workers with expansive OFTP preferred problem‐focused and proactive strategies in both low‐ and high‐emotionally salient scenarios. Workers with limited OFTP consistently preferred passive strategies irrespective of emotional salience. OFTP moderated the effect of problem‐focused strategies on psychological distress. In particular, there was a significant negative relationship between problem‐focused strategies and psychological distress among workers with expansive OFTP, but such pattern of relationship was not observed among workers with limited OFTP. Findings of this study inform the training strategies employed by practitioners to fit the developmental goals of workers in order to maximise their strengths at work.
