Relationships between psychological stress,coping and disordered eating: A review

Abstract

Objective: Psychological stress and inadequate coping skills have been hypothesized to play important roles in the etiology of disordered eating. This paper reviews the empirical evidence which has emerged regarding the proposed relationships among stress. coping skills and various forms of disordered eating. Method: A search of psychological and medical databases was conducted to identify studies examining life events, and other types of psychological stress and coping strategies, in relation to the onset of disordered eating. Results: Despite methodological limitations such as the use of non-representative samples and retrospective methodologies, evidence of relationships between stress. coping and disordered eating was obtained in the majority of studies reviewed. Discussion: The implications of these findings am discussed and suggestions for future research, including the utilization of longitudinal. prospective studies, am presented.

Relations between stress and work outcomes: The role of felt challenge, job control, and psychological strain

Recent research on reported work stress indicates stress may not always be deleterious for an individual or organization. Research in this area, however, has not yet examined a variety of work outcomes, the mechanism by which stress leads to such outcomes, and the moderators of this effect. The present study hypothesized that two types of reported stress (challenge- and hindrance-related) have a divergent relationship with work outcomes (relating to desirable and undesirable outcomes, respectively) and a similar (positive) relationship with psychological strain. We also hypothesize felt challenge as a mechanism through which challenge stress relates to desirable outcomes and job control as a moderator of the effect. Results from a heterogeneous sample of university staff employees (N=461) supported many of the hypotheses. The two types of stress differentially related to work outcomes yet both positively related to psychological strain. In addition, felt challenge mediated the relationship between challenge-related stress and work outcomes, yet the effect of challenge-related stress did not depend on job control.     

Stepparent role strain and psychological distress

In the last few decades, Spain has witnessed a slow but progressive change in predominant family models. The purpose of this work is to advance in our knowledge of stepfamilies through the perspectives and experiences of two of their members, the stepfather and the stepmother. The theoretical model examined in this investigation proposes that stepparents' role strain could have negative effects on their psychological wellbeing. It also proposes that a satisfactory couple relation could mediate in the relation between role strain and psychological wellbeing. In this study, participants were 116 stepparents who had been living for at least one year with their partner. The most relevant results showed the adequacy of the proposed model and the higher vulnerability of stepmothers in these family structures.     

Behavioral consequences of job-related stress among resident physicians: the mediating role of psychological strain

This study examined the correlations among stressors, psychological strain, and behavioral reactions in a national sample of 1785 resident physicians, 27 to 33 years old. Consistent with previous studies of resident physicians, analysis showed that those experiencing high job-related stressors experienced high psychological strain in both their personal and professional lives. Stressors were also correlated with behavioral reactions. Hierarchical regression suggested that psychological strain mediated the relations between two of the stressors and behavioral reactions to some extent. This was consistent with recent research suggesting that psychological reactions may mediate the relations between stressors and outcomes. Further research on both medical residency and the stressing process was suggested.     

The role of rumination,attentional biases and stress in psychological distress

This experimental study examines the relationship between rumination and attentional bias. Additionally, the study aims to determine, within a diathesis‐stress framework, whether rumination or attentional bias (or both) can prospectively predict psychological distress. Eighty‐one participants completed selected measures of rumination and psychological distress at time one, in addition to experimental manipulations of rumination and mood, and measures of mood and attentional bias at time two. Seventy‐three participants (90% follow‐up) completed final measures of stress and psychological distress approximately 3 weeks later. In combination with negative mood, inducing rumination decreased positive attentional bias, whilst inducing distraction increased positive attentional bias. Rumination and stress interacted to predict change in psychological distress. Negative attentional bias showed a trend towards interacting with rumination and stress to predict dysphoria. The findings supported the proposed diathesis‐stress models. In addition, a causal relationship between rumination and positive attentional bias has been empirically established for the first time.     

Cardiovascular reactions to psychological stress and abuse history: the role of occurrence,frequency, and type of abuse

Background and objectives: Extreme cardiovascular reactions to psychological stress have been associated with traumatic life experiences. Previous studies have focused on the occurrence or frequency of abuse rather than type of abuse. We examined how occurrence, frequency, and the type of abuse history are related to cardiovascular reactivity (CVR) to acute psychological stress. Design: The study consisted of between group and continuous analyses to examine the association between occurrence, type, and frequency of abuse with cardiovascular reactions to acute psychological stress. Methods: Data from 64 participants were collected. Heart rate, systolic blood pressure, and diastolic blood pressure were measured at baseline and during a standard mental arithmetic stress task. Results: Individuals who experienced abuse showed diminished CVR to acute psychological stress; this was driven specifically by the history of sexual abuse. Frequency of abuse did not relate to stress reactions. Conclusions: These findings accord with previous work suggesting a relationship between traumatic life experience and hypoarousal in physiological reactivity and extend previous findings by suggesting the relationship may be driven by sexual abuse.     

Social skills, psychological well-being, and the mediating role of perceived stress

Social skills were predicted to be associated with two indicators of psychological well-being: reduced symptoms of depression and life-satisfaction. Social skills were also predicted to be associated with a reduction in the experience of stress. This reduced stress experience was hypothesized to explain the social skills-well-being association. These predictions were tested in a sample of 500 university students who provided self-reports of social skills, well-being (depression and life satisfaction), and stress. Results supported the hypothesized relationship between social skills and greater well-being, as well as social skills and lower levels of perceived stress. The lower perceptions of stress that accompany higher levels of social skills mediated the association between social skills and depression as well as life satisfaction.

Relationships between mindfulness, self-control, and psychological functioning

The purpose of this study was to investigate whether dispositional mindfulness (the tendency to be mindful in general daily life) accounts for variance in psychological symptoms and wellbeing after accounting for the influence of dispositional self-control (the tendency to be self-disciplined, reliable, hardworking, etc.). A large sample of undergraduate students (N = 280) completed self-report measures of mindfulness, self control, psychological wellbeing, and general psychological distress (depression and anxiety, and stress). As expected, both mindfulness and self-control were positively correlated with wellbeing and negatively correlated with general distress. Mindfulness was found to account for significant variance in psychological wellbeing and general distress after accounting for self-control. In addition, mindfulness was a significant moderator of the relationship between self-control and psychological symptoms. Results show that although self-control predicts significant variance in psychological health, mindfulness predicts incremental variance, suggesting that a mindful approach to ongoing experience can contribute to mental health in persons who are highly self-disciplined and hardworking.     

Environmental stress, psychological stress and allostatic load

The mechanism by which chronic caregiving stress results in poor health is not well understood. The objective was to determine whether such a mechanism may be allostatic load, a novel concept specifying physiological systems that may suffer cumulative wear and tear following chronic stress, leading collectively to poor health. The study examines the association of allostatic load with environmental and psychological stress in the contexts of dementia caregiving and relinquishment of care, and is a 2-year longitudinal comparison of three groups: 80 new dementia spouse caregivers, 120 veteran caregivers, and 60 non-caregivers. Data comprised allostatic load markers and environmental and psychological stress measures. Cross-lagged analyses produced a statistically significant association between psychological stress and one allostatic load component (primary mediators). Psychological stress was a better predictor of primary mediators than environmental stress. Primary mediators rose with time for caregivers, but not for non-caregivers. A greater rise was evident for caregivers who had relinquished their role by the second year, although the level of psychological stress actually declined. Primary mediators are a key component of the relationship between allostatic load and prior stress. When allostatic load is treated as an outcome of stress, it is important to distinguish environmental and psychological stress.     

Human behavioral contributions to climate change: psychological and contextual drivers

We are facing rapid changes in the global climate, and these changes are attributable to human behavior. Humans produce this global impact through our use of natural resources, multiplied by the vast increase in population seen in the past 50 to 100 years. Our goal in this article is to examine the underlying psychosocial causes of human impact, primarily through patterns of reproduction and consumption. We identify and distinguish individual, societal, and behavioral predictors of environmental impact. Relevant research in these areas (as well as areas that would be aided by greater attention by psychologists) are reviewed. We conclude by highlighting ethical issues that emerge when considering how to address human behavioral contributions to climate change.     

Aerobic fitness, psychological characteristics, and cardiovascular reactivity to stress

Examined the relations among aerobic fitness (AF), psychological characteristics, and cardiovascular reactivity using 62 men divided into highly fit and less fit groups based on a maximal treadmill exercise test. Several psychological and physiological variables were measured, and subjects' cardiovascular reactivity was assessed during a mental arithmetic task and during a video game task. Highly fit subjects showed a significantly smaller increase in both diastolic blood pressure (DBP) and heart rate (HR) and reported themselves to be less anxious and less angry than less fit subjects. Furthermore, controlling for subjects' scores on a scale assessing angry temperament reduced the relationship between AF and DBP reactivity to nonsignificant levels. These results suggest that degree of dispositional anger, which covaries with increased fitness, may contribute to the apparent relationship between AF and DBP--but not HR--reactivity.     

The role of psychological climate in facilitating employee adjustment during organizational change

The current research tested a theoretical model of employee adjustment during organizational change based on Lazarus and Folkman's () cognitive-phenomenological framework. The model hypothesized that psychological climate variables would act as coping resources and predict improved adjustment during change. Two variations of this model were tested using survey data from two different organizational samples: 779 public hospital employees and 877 public sector employees. Confirmatory factor analyses and structural equation analyses were conducted in order to evaluate the models. Results showed that employees whose perceptions of the organization and environment in which they were working (that is, psychological climate) were more positive, were more likely to appraise change favourably and report better adjustment in terms of higher job satisfaction, psychological well-being, and organizational commitment, and lower absenteeism and turnover intentions.     

Psychological state and psychological strain in relation to infertility

The purpose of the study was to explore the relationship between psychological state and perceived strain in relation to fertility problems. Couples presenting at an infertility clinic completed, on two occasions seven months apart, a series of standardized measures to assess psychopathology. In addition, they completed a weekly diary rating their mood state or distress/strain over a period of 22 weeks, during which investigations and treatment were taking place. Little evidence of psychopathology was found in the sample; the weekly diaries also suggested a general lack of distress/strain, even in response to medical investigations and diagnosis. The results are discussed in the light of wide individual variations in ratings obtained from the diaries. Participants with high distress/strain scores tended to have significantly higher initial scores on the psychometric measures administered. Participants with high distress/strain scores were also more likely to show a further significant increase in distress/strain scores in relation to diagnostic information. It is argued that a task for future research is to determine the characteristics of those couples who are likely to experience difficulty in coping with the strain of infertility investigations so that counselling resources and support services can be most effectively targeted. © 1998 John Wiley & Sons, Ltd.     

Work characteristics, musculoskeletal disorders, and the mediating role of psychological strain: a study of call center employees

The demands of the modern office are thought to contribute to the development of musculoskeletal disorders. For upper body and lower back disorders, these effects are hypothesized to be mediated by psychological strain. A study of 936 employees from 22 call centers supports this hypothesis. Using logistic regression and structural equation modeling, the authors found that the relationship of workload to upper body and lower back musculoskeletal disorders was largely accounted for by job-related strain. This mediating effect was less evident for arm disorders. Contrary to expectation, job autonomy had neither a direct nor a moderating effect on any musculoskeletal disorder.     

The role of neuroticism on psychological and physiological stress responses

This study examined the influence of personality on stressor appraisals and emotional, physiological, and behavioral responses to psychosocial stress. Appraisals were used to classify participants as threatened (they believed their coping resources were inadequate relative to stressor demands) or challenged (they believed their coping resources were commensurate with stressor demands). Neuroticism predicted threat appraisals, and both were related to negative emotional experience and poor task performance. The influence of neuroticism on negative emotions and poor performance was mediated by threat appraisals. High neuroticism confers stress vulnerability, but only when conditions are construed as threatening.
