Revisiting The Association Of Lmx Quality With Percieved Role Stressors: Evidence For Inverted-U Relationships Among Immigrant Europeans, Guowei Jian

Guowei Jian

Although earlier research on leader-member exchange (LMX) theory supported a negative linear relationship between LMX quality and role stressors, recent studies suggest that a more complex, nonlinear relationship may exist between LMX quality and variables traditionally associated with it. Based on communication research of LMX and social exchange theory, the aim of this article is to revisit the relationship between LMX quality and role stressors by reconceptualizing their associations and testing the hypotheses of an inverted U relationship. A survey study among immigrant employees revealed differential effects of LMX quality on role stressors. In particular, with role conflict and role …

Relationships Among Transformational And Transactional Leadership Styles, Role Pressures, Stress Levels, And Coping Resources In Senior Queensland Catholic Education Executives, Lynette Hand, Richard Hicks, Mark Bahr

Mark Bahr

There is considerable research available on general organizational leadership but limited research in relation to religious educational organizations and the leadership styles of executive staff. The Queensland Catholic Education (QCE) executives are thought to emphasize transformational more than transactional leadership styles but little information is available on the relationships of these styles to stress within the faith-based organizations, and to the role stressors faced and levels of coping resources. This paper reports on a study of 136 QCE executive leaders (of the total 220 executives) relating leadership styles adopted, strain (stress) experienced, personal coping resources, and selected role stressors (role …

Social Motivation Is Associated With Elevated Salivary Cortisol In Boys With An Asd, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

Because social communication difficulties and stress are common in children with an ASD, and because it has been hypothesised that the two are related, the association between these two variables was investigated in a sample of 90 boys with an ASD and who were aged between 6 years and 12 years of age. The Social Responsiveness Scale (SRS) was completed by the parents of these boys about their sons, plus salivary cortisol samples were collected from the boys. Results indicated that only one aspect of the boys' SRS was significantly correlated with cortisol—Social Motivation (SM). Factor analyses revealed two discrete …

Coping And Ego Depletion: Recovery After The Coping Process, Roy Baumeister, Jon Faber, Harry Wallace

Harry M. Wallace

In this chapter, we combine a new approach to the self with a traditional, standard idea about coping in order to understand the coping process. The central idea is that many operations of the self involve the consumption of a limited resource. This resource is used in volition (e.g., choice, responsible decision-making, and active responses) and self-control. Stress makes severe demands on this resource, because people must engage in active responding and must regulate themselves so as to adapt to difficult circumstances. One major consequence of stress is that the resource becomes depleted. This will impair the person's functioning across …

Which Aspects Of Sensory Features Are Associated With Elevated Cortisol Concentrations In Boys With An Autism Spectrum Disorder?, Vicki Bitsika, Christopher Sharpley, Nicholas Andronicos, Linda Agnew, Richard Mills

Vicki Bitsika

Difficulties in Sensory Features (SF) have been included in the most recent diagnostic processes for Autism Spectrum Disorder (ASD) and are more common in children with an ASD than their non-ASD peers. In addition, these difficulties with SF have been suggested as causing elevated stress and concentrations of salivary cortisol in young people with an ASD. However, previous studies have not examined the specific aspects of SF that are associated with elevated cortisol and that was the focus of this study with 135 boys with an ASD aged 6–18 years. The boys’ mothers assessed their sons’ SF with the Sensory …

Disadvantages Of Being An Individualist In An Individualistic Culture: Idiocentrism, Emotional Competence, Stress, And Mental Health, Gregory Scott, Joseph Ciarrochi, Frank Deane

joseph Ciarrochi

Based on past cross-cultural research, it was hypothesised that people who had strong individualistic values and beliefs within an individualistic culture would have smaller social support networks, lower emotional competence, lower intentions to seek help from a variety of sources, and poorer mental health. A total of 276 first-year students attending an Australian university completed an anonymous survey assessing individual differences in individualism (i.e., idiocentrism), social support, emotional competence, hopelessness, depression, and suicide ideation. As expected, idiocentrism was associated with smaller and less satisfying social support networks, less skill in managing both self and others' emotions, lower intentions to seek …

Emotional Intelligence Moderates The Relationship Between Stress And Mental Health, Joseph Ciarrochi, Frank Deane, Stephen Anderson

joseph Ciarrochi

Despite a great deal of popular interest and the development of numerous training programs in emotional intelligence (EI), some researchers have argued that there is little evidence that EI is both useful and different from other, well established constructs. We hypothesized that EI would make a unique contribution to understanding the relationship between stress and three important mental health variables, depression, hopelessness, and suicidal ideation. University students (n=302) participated in a cross-sectional study that involved measuring life stress, objective and self-reported emotional intelligence, and mental health. Regression analyses revealed that stress was associated with: (1) greater reported depression, hopelessness, and …

Cognitive Trait Anxiety, Situational Stress, And Mental Effort Predict Shifting Efficiency: Implications For Attentional Control Theory, Elizabeth Edwards, Mark Edwards, Michael Lyvers

Mark Edwards

Attentional control theory (ACT) predicts that trait anxiety and situational stress interact to impair performance on tasks that involve attentional shifting. The theory suggests that anxious individuals recruit additional effort to prevent shortfalls in performance effectiveness (accuracy), with deficits becoming evident in processing efficiency (the relationship between accuracy and time taken to perform the task). These assumptions, however, have not been systematically tested. The relationship between cognitive trait anxiety, situational stress, and mental effort in a shifting task (Wisconsin Card Sorting Task) was investigated in 90 participants. Cognitive trait anxiety was operationalized using questionnaire scores, situational stress was manipulated through …

Effects Of Trait Anxiety And Situational Stress On Attentional Shifting Are Buffered By Working Memory Capacity, Mark Edwards, Phillipa Moore, James Champion, Elizabeth Edwards

Mark Edwards

Background and Objectives: Attentional Control Theory (ACT) predicts that trait anxiety and situation stress combine to reduce performance efficiency on tasks requiring rapid shifts in attention. Recent evidence has also suggested that working memory capacity (WMC) might moderate this relationship. We controlled for methodological difficulties in the existing literature to investigate the relationships between trait anxiety, situational stress, and WMC on attentional shifting. Design and Method: Seventy undergraduate students participated in the study. Trait anxiety was operationalized using questionnaire scores, situational stress was manipulated through a pressured counting task, and WMC was based on performance on the Automated Operation Span …

Workplace Stress, Personality, Personal Resources And Mindfulness Practices Of 21 Australian Based Counsellors, Richard Hicks, Clive Jones, Victoria Alexander

Richard Hicks

There have been several older studies of counsellors at work in Australia but none recently that have examined the relationships of full-time practising counsellors in the light of their experienced stress, their personality patterns and their resources including mindfulness attributes. The current study set out to gather extensive information on how counsellors experienced their work roles and relationships and how they coped with the circumstances they faced. A series of questionnaires was used in the study including the Occupational Stress Inventory- Revised (which yielded responses on stressors at work related to the role of the counsellor, experienced stress or strain …

The Protective Role Of Compassion Satisfaction For Therapists Who Work With Sexual Violence Survivors: An Application Of The Broaden-And-Build Theory Of Positive Emotions, Christina Samios, Lisa Abel, Amber Rodzik

Christina Samios

Therapists who work with trauma survivors, such as survivors of sexual violence, can experience compassion satisfaction while experiencing negative effects of trauma work, such as secondary traumatic stress. We examined whether the negative effects of secondary traumatic stress on therapist adjustment would be buffered by compassion satisfaction and whether the broaden-and-build theory of positive emotions could be applied to examine the factors (positive emotions and positive reframing) that relate to compassion satisfaction. Sixty-one therapists who work with sexual violence survivors completed measures of secondary traumatic stress, compassion satisfaction, adjustment, positive emotions and positive reframing. Hierarchical multiple regression analyses found that …

Hpa And Sam Axis Responses As Correlates Of Self- Vs Parental Ratings Of Anxiety In Boys With An Autistic Disorder, Vicki Bitsika, Christopher Sharpley, John Sweeney, James Mcfarlane

Vicki Bitsika

Anxiety and Autistic Disorder (AD) are both neurological conditions and both disorders share some features that make it difficult to precisely allocate specific symptoms to each disorder. HPA and SAM axis activities have been conclusively associated with anxiety, and may provide a method of validating anxiety rating scale assessments given by parents and their children with AD about those children. Data from HPA axis (salivary cortisol) and SAM axis (salivary alpha amylase) responses were collected from a sample of 32 high-functioning boys (M age = 11 yr) with an Autistic Disorder (AD) and were compared with the boys' and their …

Self-Esteem Influences On Multiple Domains: Stress, Health, Mood, And Social Identity, Kymberlee O'Brien, Hannah Lapp, Stephanie Powers, Celia Moore

Kymberlee M. O'Brien

The present investigation assessed self-esteem effects on biological and subjective chronic stress measures, including cardiovascular parameters, health indicators, and mood. Moderators were examined, including vagal tone and social identity. High self-esteem was associated with higher baseline positivity, lower baseline negativity, and lower subjective stress across numerous domains including: city stress, chaos at home, and perceived stress (all p<.05). Vagal tone moderated the relationship between self-esteem and the chronic stress measure: hair cortisol (p<.05). The high self-esteem group showed lower cortisol, particularly when coupled with high vagal tone. Individuals with low vagal tone had the highest cortisol; for those …

Mediating Factors Of Perceived Discrimination: Physiological And Affective Markers., Kymberlee O'Brien, Edward Tronick, Celia Moore

Kymberlee M. O'Brien

Early life adversity influences later health and may be mediated by psychosocial, affective, and physiological stress and immune factors. We report evidence from MIDUS biomarker project (N = 845, age 34-84, M = 55.09, SD = 11.70) confirming the predicted relationship between early adversity and frequency of diagnosed chronic illnesses (M = 2.8, SD =1.2). Specific psychosocial and physiological variables were tested as mediators. Lifetime (M = .95, SD = 1.5) and daily (M = 12.8, SD = 1.2) discrimination, urinary cortisol (M = 1.1, SD = 1.2 ug/dL), IL-6 (M =2.8, SD = 2.8 pg/mL) (all ps<.001), and …

Does The Critical Shields Stress For Sediment Transport Depend On Channel-Bed Slope?, Ishraq Alfadhli, Shu-Qing Yang, Muttucumaru Sivakumar

Ishraq Hamdan Alfadhli

This paper investigates why the observed critical Shields stress for incipient sediment motion deviates from the Shields curve. This deviation is often described in the literature as due to measurement errors and non-uniformity of channel-bed slope or flows. On the contrary, this paper hypothesises the deviation as due to the presence of vertical velocity in open channel flows. We found that the existence of vertical velocity in non-uniform flows can lead to the deviation of critical shear stress from the standard Shield's diagram that is valid only in uniform flows, and the channel bed slope could not contribute to the …

How Prostate Cancer Patients Cope: Evaluation And Refinement Of The Prostate Cancer Patients' Coping Strategies Questionnaire, Christopher Sharpley, Vicki Bitsika, David Christie

Vicki Bitsika

Background: Prostate cancer (PCa) patients suffer from identifiable stressors that may cause them anxiety and/or depression. In a previous study, an initial exploration of the ways in which PCa patients seek to cope with those stressors was described. However, several methodological limitations prevented direct comparisons of the relative effectiveness of patients’ coping strategies. To further investigate this issue, a standardised format was used to present the most commonly-used coping strategies to a new sample of PCa patients and to compare the effectiveness of those strategies. Methods: A total of 147 PCa patients completed a background questionnaire and the Prostate Cancer …

Semen Quality In Fertile Men In Relation To Psychosocial Stress, A. Gollenberg, F. Liu, C. Brazil, E. Drobnis, D. Guzick, J. Overstreet, J. Redmon, Amy Sparks, C. Wang, S. Swan

Cytoplasmic Metadherin (Mtdh) Provides Survival Advantage Under Conditions Of Stress By Acting As Rna-Binding Protein, Xiangbing Meng, Danlin Zhu, Shujie Yang, Xinjun Wang, Zhi Xiong, Yuping Zhang, Pavla Brachova, Kimberly Leslie

Xiangbing Meng

Overexpression of metadherin (MTDH) has been documented in many solid tumors and is implicated in metastasis and chemoresistance. MTDH has been detected at the plasma membrane as well as in the cytoplasm and nucleus, and the function of MTDH in these locales remains under investigation. In the nucleus, MTDH acts as a transcription co-factor to induce expression of chemoresistance-associated genes. However, MTDH is predominantly cytoplasmic in prostate tumors, and this localization correlates with poor prognosis. Herein, we used endometrial cancer cells as a model system to define a new role for MTDH in the cytoplasm. First, MTDH was primarily localized …

Social Support, Psychological Distress, And Natural Killer Cell Activity In Ovarian Cancer, S. Lutgendorf, A. Sood, B. Anderson, S. Mcginn, H. Maiseri, M. Dao, J. Sorosky, Koen De Geest, J. Ritchie, D. Lubaroff

Koen De Geest

PURPOSE: Psychosocial stress has been related to impaired immunity in cancer patients. However, the extent to which these relationships exist in immune cells in the tumor microenvironment in humans has not been explored. We examined relationships among distress, social support, and natural killer (NK) cell activity in ovarian cancer patients in peripheral-blood mononuclear cells (PBMC), ascitic fluid, and tumor-infiltrating lymphocytes (TIL). PATIENTS AND METHODS: Patients awaiting surgery for a pelvic mass suspected of being ovarian cancer completed psychological questionnaires and gave a presurgical sample of peripheral blood. Samples of tumor and ascites were taken during surgery, lymphocytes were then isolated, …

Diurnal Cortisol Dysregulation, Functional Disability, And Depression In Women With Ovarian Cancer., Aliza Weinrib, Sandra Sephton, Koen De Geest, Frank Penedo, David Bender, Bridget Zimmerman, Clemens Kirschbaum, Anil Sood, David Lubaroff, Susan Lutgendorf

Koen De Geest

BACKGROUND: Multiple alterations in circadian rhythms have been observed in cancer patients, including the diurnal rhythm of the adrenal hormone cortisol. Diurnal cortisol alterations have been associated with cancer-related physiological processes as well as psychological stress. Here we investigate alterations in diurnal cortisol rhythm in ovarian cancer patients, and potential links with depression, life stress, and functional disability.

METHODS: Women (n = 177) with suspected ovarian cancer completed questionnaires and collected salivary cortisol 3× daily for 3 consecutive days before surgery. One hundred women were subsequently diagnosed with ovarian cancer and 77 with benign disease. In addition, healthy women (n …

Social Isolation Is Associated With Elevated Tumor Norepinephrine In Ovarian Carcinoma Patients., Susan Lutgendorf, Koen De Geest, Laila Dahmoush, Donna Farley, Frank Penedo, David Bender, Michael Goodheart, Thomas Buekers, Luis Mendez, Gina Krueger, Lauren Clevenger, David Lubaroff, Anil Sood, Steve Cole

Koen De Geest

Noradrenergic pathways have been implicated in growth and progression of ovarian cancer. Intratumoral norepinephrine (NE) has been shown to increase with stress in an animal cancer model, but little is known regarding how tumor NE varies with disease stage and with biobehavioral factors in ovarian cancer patients. This study examined relationships between pre-surgical measures of social support, depressed mood, perceived stress, anxiety, tumor histology and tumor catecholamine (NE and epinephrine [E]) levels among 68 ovarian cancer patients. We also examined whether associations observed between biobehavioral measures and tumor catecholamines extended to other compartments. Higher NE levels were found in advanced …

Development Of The Distraction Coaching Index, Charmaine Kleiber, Ann Mccarthy, Kirsten Hanrahan, L. Myers, N. Weathers

Kirsten M. Hanrahan

Children's distress during medical procedures can be decreased when professionals or parents provide distraction coaching, but the quality of distraction may contribute to the variation in the results. This article describes the development of the Distraction Coaching Index (DCI), a tool for measuring the quality and frequency of distraction coaching. Nominal group technique and consensus agreement were used for concept clarification and development of behavioral indicators and descriptors. Videotapes of untrained parents, trained parents, and expert professional coaches, who provided distraction to children (4-10 years old) undergoing peripheral intravenous catheter insertion, were used to assess interrater reliability and construct validity. …

Strategies For Salivary Cortisol Collection And Analysis In Research With Children, Kirsten Hanrahan, Ann Mccarthy, Charmaine Kleiber, S. Lutgendorf, E. Tsalikian

Kirsten M. Hanrahan

Salivary cortisol has emerged in pediatric research as an easy-to-collect, relatively inexpensive, biologic marker of stress. Cortisol is highly variable and is responsive to a wide range of factors that should be considered when incorporating this measure into research with children. Strategies for sample collection include: (1) standardizing the time for sample collection, including baseline samples; (2) using consistent collection materials and methods; (3) controlling for certain drinks, foods, medications, and diagnoses; and (4) establishing procedures and protocols. Other strategies for laboratory analyses include: (1) selecting the appropriate assay and laboratory; (2) identifying units of measure and norms; and (3) …

Factors Explaining Children's Responses To Intravenous Needle Insertions, Ann Mccarthy, Charmaine Kleiber, Kirsten Hanrahan, M. Zimmerman, N. Westhus, S. Allen

Kirsten M. Hanrahan

BACKGROUND: Previous research shows that numerous child, parent, and procedural variables affect children's distress responses to procedures. Cognitive-behavioral interventions such as distraction are effective in reducing pain and distress for many children undergoing these procedures. OBJECTIVES: The purpose of this report was to examine child, parent, and procedural variables that explain child distress during a scheduled intravenous insertion when parents are distraction coaches for their children. METHODS: A total of 542 children, between 4 and 10 years of age, and their parents participated. Child age, gender, diagnosis, and ethnicity were measured by questions developed for this study. Standardized instruments were …

The Sensitivity And Specificity Of A Simple Test To Distinguish Between Urge And Stress Urinary Incontinence., Jeanette Brown, Catherine Bradley, Leslee Subak, Holly Richter, Stephen Kraus, Linda Brubaker, Feng Lin, Eric Vittinghoff, Deborah Grady

Catherine S. Bradley

BACKGROUND: Urinary incontinence is common in women. Because treatments differ, urge incontinence should be distinguished from stress incontinence. To make this distinction, current guidelines recommend an extensive evaluation that is too time-consuming for primary care practice. OBJECTIVE: To test the accuracy of a simple questionnaire to categorize type of urinary incontinence in women. DESIGN: Multicenter, prospective study of the accuracy of the 3 Incontinence Questions (3IQ) compared with an extended evaluation to distinguish between urge incontinence and stress incontinence. SETTING: 5 academic medical centers in the United States. PARTICIPANTS: 301 women enrolled from April to December 2004 who were older …
