The effects of gender,long-term need for recovery and trait inhibition-rumination on morning and evening saliva cortisol secretion

Abstract

The aim of this study was to investigate the long-term effects of need for recovery from work and trait rumination on saliva cortisol secretion. The sample consisted of 76 white-collar workers, 52 men and 24 women who had previously provided baseline data four years earlier and volunteered to participate in the present study. In the present study, saliva cortisol secretion was measured over seven consecutive days, on awakening, and at 10 p.m. No relationships were found between the independent variables and morning saliva cortisol levels. High trait rumination at baseline, however, was significantly related to higher evening cortisol levels for both women and men. Baseline need for recovery from work was strongly related to evening cortisol secretion for women, but in the opposite direction than expected. The present results add to the small but equivocal body of literature that has examined the long-term effects of work strain on cortisol secretion.     

Missed Opportunities: Newspaper Reports of Domestic Violence

News coverage can influence public views of important health problems, including domestic violence (DV). To understand how newspaper reports frame DV, this study examined 187 articles published across a single state over a one-year period. Coded variables included characteristics of the newspapers and articles; incident details; common DV themes (e.g., victim blame; DV as isolated or rare); and education, resources, and community context. Approximately one-third of articles framed DV using themes that might misinform the public about DV (e.g., victim blame). The majority of articles missed opportunities to provide educational information or resources about DV and failed to situate DV in a community context. These findings point to missed opportunities for newspapers to provide comprehensive information and resources to the public.     

Executive Functioning and Gambling: Performance on the Trail Making Test is Associated with Gambling Problems in Older Adult Gamblers

ABSTRACT

Rates of gambling problems in older adults have risen with increased accessibility of gambling venues. One possible contributor to problem gambling among older adults is decreased self-control brought about by diminished executive functioning. Consistent with this possibility, Study 1 revealed that older adults recruited from gambling venues reported greater gambling problems if they also experienced deficits in executive functioning, measured via the Trail Making Test. Study 2 replicated this finding and demonstrated that problem gambling is associated with increased depression among older adults, mediated by increased financial distress. These studies provide support for the hypothesis that older adult gamblers who have executive functioning problems are also likely to have gambling problems.     

Using Acceptance and Commitment Therapy to Guide Exposure-Based Interventions for Posttraumatic Stress Disorder

Exposure is considered one of the most effective interventions for PTSD. There is a large body of research for the use of imaginal and in vivo exposure in the treatment of PTSD, with prolonged exposure (PE) therapy being the most researched example. Acceptance and commitment therapy (ACT) has sometimes been called an exposure-based treatment, but how exposure is implemented in ACT for PTSD has not been well articulated. Although support for the use of ACT in PTSD treatment is limited to a handful of case studies and open trials, research suggests ACT is particularly useful in flexibly targeting avoidance behavior—arguably the most important process in the continued maintenance of PTSD symptoms. The purpose of this paper is to explore the use of exposure within ACT in PTSD treatment. Through an overview of PE and ACT, and with the use of case examples, we describe how ACT principles and techniques may inform exposure-based treatments for PTSD in order to create more flexible approaches. In addition, understanding exposure within an ACT framework may also contribute to clarifying processes of change.     

Is There a Developmental Slump in Creativity in China? The Relationship Between Organizational Climate and Creativity Development in Chinese Adolescents

The major objectives of this study were to determine the characteristics of creativity development of Chinese children, the creative organizational climate of Chinese schools, and the relations among them. The results provided evidence that the creativity scores of children in elementary school were significantly higher than those of children in middle school. The teachers' evaluation of the creative organizational climate of the elementary school was significantly higher than that of the middle school. When the two variables were analyzed together, both the creative organizational climate of schools and the creative thinking development of children decreased during the children's development. Moreover, the creativity and climate scores were highly correlated, and the results from a path analysis suggested that a school's creative organizational climate has a significant impact on all seven dimensions of creativity measured in this study.     

The Relationship Between Childhood Onset Obesity and Psychopathology in Adulthood

We administered the Symptom Checklist (Derogatis, 1975; SCL-90-R) to 37 obese subjects in outpatient treatment for obesity. Patients with early onset obesity demonstrated a greater frequency and higher levels of emotional distress and psychiatric symptomatology than patients with late onset obesity. Individuals who developed obesity in childhood showed more psychopathology than those who developed obesity later in life. Overall, these findings support the belief that obesity is characteristically associated with greater internal psychological conflict. These findings further suggest that childhood obesity could serve as a predictor variable for possible future psychological disturbance in obese populations.     

Work conditions and employees' self-set goals: goal processes enhance prediction of psychological distress and well-being

Although previous theory and research suggest that employee well-being should be predicted by work conditions (viz., Karasek and colleagues' job demands-control-social support [J-DCS] model), other factors are also likely to be important. In this study, the authors consider correlates of employee psychological distress and well-being using a goal-focused approach grounded in Ford's (1992) motivational systems theory. Specifically, work conditions and midlevel work goal processes (WGP) were examined in a questionnaire study of health care employees. Regarding predictions derived from the J-DCS model, the authors found full support for the iso-strain, partial support for the nonlinearity, and no support for the buffer hypothesis. Of importance, however, WGP (i.e., cognitions and emotions involved in the pursuit of self-set work goals) explained variance in job satisfaction, burnout, depression, and somatic complaints, over and above that of the J-DCS model. This suggests that investigation of WGP can enhance our understanding of employee psychological distress and well-being.     

Health-promoting physical activity of adults with mental retardation

This literature review describes the physical activity behavior of adults with mental retardation consistent with the U.S. Surgeon General's recommendation of 30 minutes of moderate intensity physical activity on 5 or more days per week. The proportion of participants achieving this criterion ranges from 17.5 to 33%. These data are likely to be generous estimates of activity as individuals included in physical activity studies to date have been relatively young and healthy volunteers with mild to moderate limitations. Major sources of physical activity were walking and cycling for transport, chores and work, dancing, and Special Olympics. There is a pressing need to conduct studies using appropriately powered representative samples and to validate measures that assess physical activity less directly; including methodologies in which proxy respondents are used. Accurate information about existing patterns of behavior will enhance the development of effective strategies to promote physical activity among persons with mental retardation.     

The involvement of the orbitofrontal cortex in learning under changing task contingencies

Previous investigations examining the rat prefrontal cortex subregions in attentional-set shifting have commonly employed two-choice discriminations. To better understand how varying levels of difficulty influence the contribution of the prefrontal cortex to learning, the present studies examined the effects of orbitofrontal cortex inactivation in a two- or four-choice odor reversal learning test. Long-Evans rats were trained to dig in cups that contained distinct odors. In the two-choice odor discrimination, one odor cup was always associated with a cereal reinforcement in acquisition while the opposite odor cup was associated with a cereal reinforcement in reversal learning. In the four-choice odor discrimination, an additional two cups containing distinct odors were used that were never associated with reinforcement in acquisition or reversal learning. Bilateral infusions of the GABA-A agonist, muscimol (0.5 microg) into the orbitofrontal cortex did not impair acquisition of either the two- or four-choice discrimination task. However, muscimol infusions into the orbitofrontal cortex impaired two- and four-choice reversal learning. In the two-choice odor reversal, muscimol treatment selectively increased perseverative errors. In the four-choice odor reversal, muscimol treatment increased perseverative, regressive, as well as irrelevant errors. These findings suggest that the orbital prefrontal cortex not only enables task switching by supporting the initial inhibition of a previously relevant choice pattern, but under increasing task demands also enables the reliable execution of a new choice pattern and reduction of interference to irrelevant stimuli.     

Evidence of Poor Planning in Children with Attention Deficits

This study examined the planning performance of children with attention deficits, and also investigated the possible interactions between inattention and anxiety in the performance of executive function tasks. A group of 98 children (grades 4 and 6), derived from an initial group of 550, were assigned to an attention difficulties group (AD) and a control group (n = 49 each) based on their scores on a variety of cognitive attention measures and teacher scales of attention and hyperactivity. The two groups were matched on age, gender, parental education, non-verbal and verbal ability. They were compared on Crack-the-Code (C-t-C) action-planning task, embedded and ambiguous figures and Theory of Mind tasks. Analyses indicated that the failure of AD children on cognitive performance measures is linked to planning impairments. The co-occurrence of anxiety, in turn, did not interact with inattention to affect planning performance differentially. Implications of these findings for the current discussion about the cognitive and emotional processes underlying impaired performance among children with attention deficits on executive control tasks are discussed.
