OBJECTIVES: This study was designed to investigate how the interaction between the ability of medical residents (doctors in postgraduate training) to cope with stress and their working conditions might affect their level of job-related stress. METHODS: A self-administered questionnaire was distributed to 549 first-year medical residents at 38 postgraduate education hospitals in Japan, 1-2 months after the start of clinical training. The questionnaires contained the 29-item Sense of Coherence (SOC) Scale, the Brief Scales for Job Stress (BSJS), the 12-item General Health Questionnaire (GHQ-12) and questions on basic conditions such as working hours. Sense of coherence is an important concept from the viewpoint of salutogenesis theory and influences stress recognition style. People with a strong SOC have a high ability to cope with stress. RESULTS: The mean +/- standard deviation (SD) score on the SOC Scale was 134.5 +/- 20.5. All participants were classified into three groups according to their SOC Scale scores. Although the objective working conditions of the three groups were statistically similar, the group with the weakest SOC Scale score showed poorer mental health status (p < 0.05) and scored lower for 'reward from work' compared with the groups with stronger SOC scores (p < 0.05). The weaker SOC group also scored higher for 'mental workload' and 'problems in personal relationships' than the other two groups (p < 0.05). Moreover, the weak SOC group scored less for 'support from colleagues and superiors' than the strong SOC group (p < 0.05). A stepwise multiple regression analysis for GHQ-12 score was conducted (R(2) = 0.45). 'Sleep time', 'workload', 'mental workload' and 'problems in personal relationships' were positively correlated with GHQ-12 scores. 'Reward from work' was negatively correlated with GHQ-12 scores. CONCLUSIONS: Residents' mental health was associated not only with working conditions, but also with their attitudes towards those working conditions. Enhancing residents' sense of 'reward from work' might be important in reducing their reactions to stress.
