The Daily Stress Inventory: Validity and effect of repeated administration

The Daily Stress Inventory (DSI) is a self-report measure of minor stressors which is administered daily. One test of the validity of a measure of daily stress is its sensitivity to the difference between the stressors of workdays and those of weekends. A second concern in establishing the validity of a test administered repeatedly is that self-monitoring may influence the obtained scores. The present study investigated these two issues using a sample of 70 community adults who reported full-time employment. These subjects provided a week of self-monitoring with the DSI. The results indicated that the DSI was sensitive to the difference between weekends and weekdays. The analyses of the effect of repeated administration suggested that the first day of self-monitoring may differ from the other days of self-monitoring. When the first day was eliminated, there was no significant difference among the days of self-monitoring, and the difference between the weekdays and the weekends remained. The data suggest that the DSI is a valid measure of the construct of daily stress and that any influence of repeated self-monitoring with the scale may be easily resolved.     

A daily diary study of the relationships among daily self-compassion,perceived stress and health-promoting behaviours

Previous studies consistently found that trait self-compassion is positively associated with health-promoting behaviours, and perceived stress mediates the relationship. The current study primarily aimed at examining whether state self-compassion varying from day to day (daily self-compassion) played the same role as trait self-compassion in improving health-promoting behaviours and whether or not perceived stress would be the mediator in this relationship. Eighty-nine Chinese employees were recruited to finish demographic information and the trait measure of self-compassion first, and then finish daily diaries for seven consecutive days. Daily diary measures included daily self-compassion, perceived stress and health-promoting behaviours including both eating behaviours and exercise behaviours. The results of 1-1-1 multilevel mediation analyses showed that, at both the within- and between-person level, daily self-compassion could positively predict daily eating behaviour through the reduction of perceived stress. However, daily self-compassion did not influence exercise behaviour at both levels. The results of 2-1-1 multilevel mediation analyses cross-validated the between-person relationships in the 1-1-1 multilevel mediation models. These results suggest that, both short-term interventions aiming at increasing state self-compassion and long-term interventions aiming at increasing trait self-compassion can benefit one's eating behaviours through the reduction of stress.     

Ethnicity,Life Satisfaction,Stress, Familiarity,and Stigma Toward Mental Health Treatment

The authors examined the relative contribution of ethnicity, life satisfaction, level of stress, familiarity with mental health treatment, and self- and public stigma on attitudes toward mental health treatment among a diverse sample (N = 632) of adults. Results indicated that ethnicity, stress, familiarity, and self-stigma of mental illness were significant predictors of attitudes. Additionally, familiarity with mental health treatment moderated the relationship between public stigma and attitude.     

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.     

高中学生心理应激及其中介变量的研究

学生的心理应激与心理健康问题日益受到人们的关注。本研究对浙江省范围内的４３７名高中学生进行应激源、中介变量和应激反应方面的调查研究,并在此基础上,对高中学生的心理应激过程作了较详细的探讨。研究表明：（１）高中学生的主要应激源是学习压力及与家庭亲友的人际关系问题,（２）对高中学生的应激反应有影响的中介变量主要是社会支持和“问题解决”、“逃避”等应对策略。本研究结论认为,在高中学生的心理卫生工作中要注意减轻他们的学习压力,加强社会支持系统的建立及积极应对方式的教育。     

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.
