Organisational factors, individual characteristics and social support: what determines the level of social support?

A large body of research has linked social support to health, but there are fewer studies that have focused on factors that influence the level of social support available and/or perceived by employees in different organisations. This cross-sectional study therefore investigated the relationship between on the one hand, organisational, individual and socio-demographic factors and on the other, the level of social support at the workplace, i.e., the degree of supervisor support and a supportive work atmosphere. Organisational variables (job demands, job control, job content), individual (self-esteem, mistrust) and socio-demographic variables (type of employer, occupational position, age, gender and educational level) were used as independent variables in the analyses. The sample consisted of 16,144 individuals at a variety of different organisations in Sweden, who had responded to a questionnaire covering different psychosocial and psychological stress factors ("the Stress Profile"). Multiple hierarchical regression analyses were performed separately for each of the two dependent variables, which yielded almost identical results, and indicated that organisational determinants, particularly perceived job control, had the largest impact on the degree of social support.

Psychosocial risk factors for coronary heart disease, their importance compared with other risk factors and gender differences in sensitivity.

BACKGROUND: Few studies have focused on risk factors in women's lives concerning psychosocial factors and coronary heart disease (CHD). The present study is one of a series in which a wide range of psychosocial factors will be analysed with a focus on women. Women and men have been compared with respect to sensitivity to psychosocial risk factors regarding CHD. The importance of psychosocial risk factors for women, compared with biomedical risk factors has also been studied. METHODS: A questionnaire (The Stress Profile) was answered by 538 rehabilitation participants (97 women, 441 men) and a reference group (5308 women, 5177 men), aged 40-65 years. Psychosocial factors were investigated using means and b-coefficients. Comparisons between psychosocial and biomedical risk factors were made, with respect to the product of the beta-coefficient and the standard deviation for each compared risk factor. RESULTS: Significant differences appeared concerning five areas: work content, workload and control, physical stress reactions, emotional stress reactions and burnout. All showed that the relative sensitivity was larger for women than for men. Predictive psychosocial risk factors for women with respect to CHD were physical stress reactions, emotional stress reactions, burnout, family relationships and daily hassles/satisfactions, and they were on approximately the same level as biomedical risk factors. CONCLUSIONS: Women appear to be more sensitive than men with respect to psychosocial risk factors for CHD, and the predictive ability of psychosocial risk factors shows great importance. Actions against unhealthy psychosocial conditions are recommended. Both presumptive CHD patients and others might benefit from preventive actions, and since women are more sensitive they will probably gain more than men.

Psychophysiological correlates of organizational change and threat of unemployment among police inspectors.

The study examined psychosocial work-conditions and physiological reactions among thirty-six police inspectors (median age 45 years, 81% males) who participated in a reorganization. At this time, subjects were threatened by unemployment and had to re-apply for their positions in a new police district. Data were collected during the reorganization and at three years follow-up, by means of questionnaires (Stress Profile) and blood samples. The blood samples were used to determine serum levels of gamma-glutamyltransferase (GGT), glucose, lipids, prolactin, testosterone and cortisol. The results show a positive association between worry about employment and symptoms of burnout during the reorganization. Mean scores for the Stress Profile sub-scales worry about employment (p<.01) and work-load (p<.05) decreased between measurements, but an impairment in relationships with management was noticed (p<.05). No significant changes were observed in terms of self-rated health complaints. Significant decreases in total cholesterol (p<.0001), LDL-cholesterol (p<.0001), LDL/HDL-ratio (p<.01), prolactin (p<.0001), as well as increases in testosterone (p<.01) and cortisol (p<.001) were observed for the whole sample. Glucose decreased with marginal significance (<.07). Controlling for age and gender, multivariate regression analyses showed that subjects who reported deteriorations in satisfaction with work manifested the most modest decreases in prolactin (p<.05). Also, the decrease in glucose was larger for subjects who experienced impairments in satisfaction with work (p<.05), information (p<.05), task-oriented leadership, (p<.05), and respect and dignity (p<.05). Subjects who perceived deteriorations in the ethical and moral standards of the organization increased their cortisol level to a lower degree than their counterparts (p<.05). Favorable changes in employment status and psychosocial work environment seem to be related to improved physiological functioning.

Serum lipids and mood in working men and women in Sweden.

STUDY OBJECTIVE: To explore the link between serum cholesterol and suicide by investigating the relation between serum lipids and depressive symptoms. DESIGN: This was a cross sectional study of the relation between serum cholesterol, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, and triglycerides on the one hand and depressive symptoms as expressed in a questionnaire on the other. SETTING: An organisational development programme in industry with assistance from occupational health care. PARTICIPANTS: A total of 644 male and 261 female employees (mainly white-collar workers) participated. MAIN RESULTS: Total cholesterol and LDL cholesterol values were lower in those men who, sometimes, often, or very often, had experienced low mood or glumness during the past month compared with those who had not. Serum triglyceride concentrations did not differ between the groups. In women, however, the serum triglyceride value, but not the total cholesterol or LDL cholesterol, was lower in those who reported low mood, depression, or anxiety during the past six months. CONCLUSIONS: Decreasing appetite as a consequence of depression in men would probably lead to both decreasing cholesterol and triglyceride concentrations. Thus, these data indicate the presence of some other explanation for the relation between the level of LDL cholesterol and depressive symptoms in men.
