Short-term effects of occupational stressors on daily mood and health complaints.

Related daily changes in 2 job conditions, workload and social interaction with co-workers and supervisors, to daily mood and health complaints. 52 air-traffic controllers (ATCs) completed measures of subjective well-being and perceived job conditions on 3 consecutive days; objective indicators of daily workload (air traffic volume and visibility at the airport) were also obtained. The results indicate that increases in job stressors are associated with a same-day deterioration in physical and psychological well-being. On days in which workload was perceived to be high, ATCs reported more health complaints and moods that were more negative and less positive. On days in which there was greater air traffic volume (objectively measured), ATCs reported moods that were more negative. On days in which interactions with co-workers and supervisors were described as more distressing, ATCs reported moods that were more negative and less positive.

Conservation of resources theory, perceived stress, and chronic fatigue syndrome: Outcomes of a consumer-driven rehabilitation program.

Objective: To evaluate the impact of a consumer-driven rehabilitation program on perceptions of loss and gain of interpersonal relationships, energy, material objects, work benefits and opportunities, well-being, and experiences of mastery in persons with chronic fatigue syndrome. Study Design: Participants were randomly assigned to a program group (n = 23) or a control group (n = 24). Outcomes were assessed (a) at baseline, (b) after program participants completed an illness management group, and (c) after they completed one-on-one peer counseling. Setting: A community-based advocacy organization for individuals with disabilities. Interventions: Four months of illness management groups followed by 7 months of one-on-one peer counseling emphasizing goal setting and goal attainment. Main Outcome Measure: The Conservation of Resources Evaluation scale. Results: Significant gains were observed for program participants across all categories of resource gain--interpersonal, energy, material, work, well-being, and mastery resources. Effect sizes were moderate to large. Conclusions: Programs in which participatory action research methods are used may have a positive impact on resource acquisition for individuals with chronic fatigue syndrome.

Gender differences in fire fighter job stressors and symptoms of stress

This study described gender differences in fire fighter appraisal of job stressors and symptoms of stress. A sample of 670 male and 41 female fire fighters responded to an anonymous mail survey consisting of three standardized and investigator-developed questionnaires. Male and female fire fighter respondents were more similar than different on both job stressor and symptoms of stress measures. Five job stressors were ranked the most "bothersome" by both males and females during the last 10 shifts worked. These were: sleep disturbance, wage/benefit concerns, job skill concerns, substandard equipment, and safety concerns. Of these five job stress factors, only one gender difference was noted. Female fire fighters reported significantly higher scores than males on job skill concerns. Job discrimination reported by female respondents was significantly higher than for males (t = 3.51, p < .0001) even though it was not ranked among the five most stressful factors. Partial correlations computed between job stressors and symptoms of stress, while controlling for the number of years as a fire fighter, were of moderately high magnitude for both genders and similar to simple correlations computed. These results suggest that the number of years of service did not account for gender differences reported.     

Cefotiam-induced contact urticaria syndrome: an occupational condition in Japanese nurses

Estradiol and progesterone receptors in the endometrium of eight patients with habitual abortion in proliferative and secretory phases were measured by DCC. The serum estradiol (E2) and progesterone (P) were detected by radioimmunoassay, and the endometrium was histologically studied. The results showed that the level of serum E2 was normal in the proliferative and secretory phases. In 5/8 patients, the serum P level was below 11 ng/ml. The estradiol receptor of patients was not different from that of normal women in the proliferative and secretory phases, but the progesterone receptor was significantly lower than that of normal women in the proliferative and secretory phases. These suggest that the lower level of progesterone and progesterone receptor in the endometrium may be one of the causes of habitual abortion.     

Critical incidents and chronic stressors at work: Their impact on forensic doctors.

Workers in medium- or high-risk professions are often confronted with critical incidents at the workplace. The impact of these acute stressors may be serious and enduring. Many workers also experience chronic job stressors, such as work overload or role conflicts. This study examined the frequently neglected relationship of acute and chronic stressors with self-reported health symptoms, such as posttraumatic responses, fatigue, and burnout. This association was investigated in a sample of forensic doctors in the Netherlands (N = 84). It was found that the more traumatic events the respondents experienced, the more problems they reported in coping with the traumatic events. Chronic job stressors were associated with posttraumatic responses (intrusions and avoidances) and with burnout and fatigue. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Impact of chronic and acute stressors on daily reports of mood.

Compared the relative impact of major life events, chronic stressors, and minor daily stressors on daily reports of mood. Analyses are based on daily diary data combined with interview data derived from a longitudinal study of 96 women (mean age 33.1 yrs) sampled from the population of persons using the services of a neighborhood health center. Ss kept daily diaries for 28 days following initial personal interviews. The Affect Balance Scale was used as a baseline measure of psychological well-being. The most important direct determinants of mood were found to be concurrent daily stressors and physical symptoms, and previous levels of psychological well-being. Life events and chronic stressors had indirect effects on mood through these other variables. Results confirm and extend previous studies on the determinants of short-term changes in mood. The advantages and disadvantages of the temporal aggregation of time-series data are discussed. (44 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relation of stressors and depressive symptoms to clinical progression of viral illness

OBJECTIVE: The aim of this research was to determine whether and in whom stressors and depressive symptoms facilitate clinical recurrence of herpes simplex virus (HSV) and progression of HIV. METHOD: Meta-analytic techniques were used to review the relations of stressors and depressive symptoms to clinical recurrence of HSV in 16 published studies and to indicators of HIV progression in 19 published studies. The authors calculated average effect sizes, performed fixed effect and random effect inferential analyses, tested for heterogeneous findings, and identified potential moderating variables. RESULTS: Depressive symptoms were associated with a slightly increased risk of HSV recurrence and increased reports of HIV-related symptoms, whereas stressors were not. However, depressive symptoms were not associated with objective indicators of accelerated HIV progression. Stressor studies, especially those that ascertained population-specific life events, found numerical and functional decrements in circulating natural killer cell populations. The candidate moderators identified include, for HSV recurrence, age, sex, and medication status, and for HIV-related symptoms, age, race, disease stage, and co-infection with HSV. CONCLUSIONS: Depressive symptoms, but not stressors, increase the risk of HSV recurrence generally. Depressive symptoms do not appear to accelerate HIV progression ubiquitously, although they are associated with increased reporting of HIV-related symptoms. Future studies that ascertain population-specific stressors should determine whether reductions in cytotoxic lymphocytes influence HIV disease progression. Moreover, researcher should investigate the role of the identified moderators and recognize psychoimmune moderators in existing and novel study groups. These analyses could confirm that certain individuals are especially susceptible to the effects on disease progression of stressors, depressive symptoms, or both.     

Chronic occupational stressors, self-focused attention, and well-being: Testing a cybernetic model of stress.

By using a cybernetic approach to occupational stress, it was hypothesized that the relationship between chronic work stressors and strain would be stronger among individuals high in private self-consciousness than among individuals low in private self-consciousness. Moderated regression analyses, using a sample of 135 blue-collar workers, revealed strong support for this hypothesis. This finding is antithetical to prior research showing that self-focused attention may buffer the effect of acute life events (B. Mullen and J. Suls [see PA, Vol 68:3591]; J. Suls and B. Fletcher [see PA, Vol 73:21993]). The results of the present study in conjunction with prior research suggest that the type of stressor (acute vs. chronic) examined may be a boundary condition influencing the direction of Stressor?×?Self-Focused Attention interactions. Implications for future research and stress management are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Fibromyalgia and chronic fatigue: the holistic perspective

Fibromyalgia syndrome (FMS) and chronic fatigue syndrome (CFS) are not new conditions, but they are receiving more attention as more research is conducted. These two conditions are primarily women's health problems. In some instances, there may be a genetic predisposition for these conditions. The impact of FMS and CFS can be devastating both physically and emotionally. The treatment plan must be interdisciplinary and holistic and include alternative therapies if the client and family are to be truly supported and helped in coping with these chronic conditions.     

A comparison of primary stressors, secondary stressors, and depressive symptoms between elderly caregiving husbands and wives: The caregiver health effects study.

The present study examined gender differences in the experience of primary and secondary caregiving stressors, depressive symptoms, and their interrelationships using a sample of 283 elderly spouse caregivers (145 women, 138 men). Two primary stressors, two secondary stressors, and depressive symptoms were assessed. In general, t-tests indicated that caregiving husbands experience fewer stressors and depressive symptoms than their female counterparts. Multiple group analysis revealed that the primary stressors were more useful in explaining variance associated with the secondary stressors for women than men and that the path coefficients linking amount of caregiving assistance to caregivers' activity restriction was significantly different across men and women. Other paths linking primary stressors, secondary stressors, and depressive symptoms, however, were statistically equivalent across men and women. Hence, although caregiving women and men may vary in their reports of caregiving stressors, the complexity of the caregiving experience appears to be quite uniform for both groups.

Modifiers of non-specific symptoms in occupational and environmental syndromes

Many occupational and environmental health hazards present as an increased reporting of non-specific symptoms such as headache, backache, eye and respiratory irritation, tiredness, memory problems, and poor concentration. The pattern and number of such symptoms is surprisingly constant from hazard to hazard suggesting that common psychological and social factors, not directly related to the exposure may be involved. A recent workshop (see acknowledgements) was held to review the pattern of symptoms in varying hazardous situations and the psychological mechanisms behind the genesis and maintenance of symptoms. The involvement of both direct physicochemical and psychological mechanisms in symptom generation and reporting in any situation was discussed and is reported here. A model that identifies the issues that need to be considered in any epidemiological study based on the incidence or prevalence of non-specific symptoms is proposed.     

Illusion of control: Invulnerability to negative affect and depressive symptoms after laboratory and natural stressors.

Examined whether individual differences in susceptibility to the illusion of control predicted differential vulnerability to depressive responses after a laboratory failure and naturally occurring life stressors. The illusion of control decreased the likelihood that Ss (N?=?145) would (1) show immediate negative mood reactions to the lab failure, (2) become discouraged after naturally occurring negative life events, and (3) experience increases in depressive symptoms a month later given the occurrence of a high number of negative life events. In addition, the stress-moderating effect of the illusion of control on later depressive symptoms appeared to be mediated in part by its effect on reducing the discouragement Ss experienced from the occurrence of negative life events. These findings provide support for the hopelessness theory of depression and for the optimistic illusion–mental health link. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Occupational health nurses and occupational hygiene: a study of South African nurses' attitudes

The objectives of this study were to assess the current occupational hygiene practices of occupational health nurses and to assess their attitudes to the identification and initial quantification of workplace hazards. A questionnaire was mailed to all occupational health nurses registered with the South African Society of Occupational Health Nurses. Responses were obtained from 221 (53.7%). Responders and non-responders did not differ on key characteristics. Only 14 (6%) of the respondents performed occupational hygiene tasks as part of their routine work and only 31 (14%) volunteered hazard identification and quantification as tasks that would significantly improve practice. Nevertheless, when asked directly, 120 (54%) agreed that occupational hygiene fell into the ambit of occupational health nursing. Over 70% were positive about receiving theoretical and practical hygiene training. Constraints to greater hazard identification included limited time and resources and concern about intruding into the domains of other practitioners. Sufficient numbers of occupational health nurses were interested in identifying hazards in the workplace for training courses to be planned and offered now; however, restraints to practice need to be clarified and removed for these new skills to be used effectively.
