Associations of psychosocial working conditions with self-rated general health and mental health among municipal employees

Psychosocial work environment and burnout among emergency medical and nursing staff

OBJECTIVES

The prevalence of burnout syndrome is increasing among doctors and nurses. The aim of this study was to analyse the relationship between the psychosocial work environment and burnout syndrome among emergency medical and nursing staff in Spain. A secondary aim was to determine if the effect of this psychosocial work environment on burnout was different for doctors and nurses.

METHODS

A cross-sectional survey was carried out by means of a mail questionnaire among 945 emergency doctors and nursing staff of Spain. The outcome variable was three dimensions of burnout syndrome [emotional exhaustion (EE), personal accomplishment (PA), depersonalisation (DP)]. The explanatory variable was that psychosocial work environment evaluated according to Karasek and Johnson's demand-control model. The adjusted odds ratios (OR) and their 95% confidence intervals were calculated by logistical regression.

RESULTS

The probability of high EE was greater among those exposed to high psychological demands, OR 4.66 (2.75-7.90), low job control, OR 1.65 (1.04-2.63), and low supervisors' social support, OR 1.64 (1.01-2.59). Emotional exhaustion dimension was negatively influenced by low control only among doctors. Those exposed to low job control had a higher risk of low PA, OR 2.55 (1.66-3.94). There was no evidence of negative effect of psychosocial risk factors on the DP. Prevalence of EE and PA was higher among doctors and nurses.

CONCLUSIONS

The presence of risk factors derived from work organisation within the work place (psychosocial risk factors) increases the probability of presenting burnout syndrome and, above all, EE.

Injustice at work and incidence of psychiatric morbidity: the Whitehall II study

BACKGROUND

Previous studies of organisational justice and mental health have mostly examined women and have not examined the effect of change in justice.

AIM

To examine effects of change in the treatment of employees by supervisors (the relational component of organisational justice) on minor psychiatric morbidity, using a cohort with a large proportion of men.

METHODS

Data are from the Whitehall II study, a prospective cohort of 10 308 white-collar British civil servants (3143 women and 6895 men, aged 35-55 at baseline) (Phase 1, 1985-88). Employment grade, relational justice, job demands, job control, social support at work, effort-reward imbalance, physical illness, and psychiatric morbidity were measured at baseline. Relational justice was assessed again at Phase 2 (1989-90). The outcome was cases of psychiatric morbidity by Phases 2 and 3 (1991-93) among participants case-free at baseline.

RESULTS

In analyses adjusted for age, grade, and baseline physical illness, women and men exposed to low relational justice at Phase 1 were at higher risk of psychiatric morbidity by Phases 2 and 3. Adjustment for other psychosocial work characteristics, particularly social support and effort-reward imbalance, partially attenuated these associations. A favourable change in justice between Phase 1 and Phase 2 reduced the immediate risk (Phase 2) of psychiatric morbidity, while an adverse change increased the immediate and longer term risk (Phase 3).

CONCLUSION

This study shows that unfair treatment by supervisors increases risk of poor mental health. It appears that the employers' duty to ensure that employees are treated fairly at work also has benefits for health.

Associations of SF-36 mental health functioning and work and family related factors with intentions to retire early among employees

OBJECTIVE

To examine the associations of mental health functioning (SF-36) and work and family related psychosocial factors with intentions to retire early.

METHODS

Cross sectional survey data (n = 5037) from the Helsinki Health Study occupational cohort in 2001 and 2002 were used. Intentions to retire early were inquired with a question: "Have you considered retiring before normal retirement age?" Mental health functioning was measured by the Short Form 36 (SF-36) mental component summary (MCS). Work and family related psychosocial factors included job demands and job control, procedural and relational justice, conflicts between work and family, and social network size. Multinomial regression models were used to analyse the data.

RESULTS

Poor mental health functioning, unfavourable psychosocial working conditions, and conflicts between work and family were individually related to intentions to retire early. After adjustments for all work and family related factors the odds ratio for low mental health functioning was halved (from OR = 6.05 to 3.67), but nevertheless the association between poor mental health functioning and strong intentions to retire early remained strong.

CONCLUSIONS

These findings highlight not only the importance of low mental health and unfavourable working conditions but also the simultaneous impact of conflicts between work and family to employees' intentions to retire early.
