[Sense of coherence, stressful life events and psychological health].
Aaron Antonovsky's Sense of Coherence (SOC), as a stable disposition of personality that serves as a major coping resource for the preservation of health, has been widely used in many studies. However, few empirical studies are conducted on the concept of SOC. We examined the stability of SOC and the buffering effect of SOC on the psychological health in dealing with stressful life events. The subjects were 200 adults randomly selected in Tokyo, and follow-up survey was conducted one year after the first survey. Goldberg's General Health Questionnaire (GHQ) was used for assessing psychological health. Antonovsky's SOC scale was translated into Japanese (and reverse translated) in this study. The test-retest reliability of SOC scale was 0.78. Cronbach's alpha was 0.91. The factors related to the SOC supported previous findings and Antonovsky's theory about the positive correlation with educational and economic status. In the follow-up survey, the subjects were also asked about the experience of 56 stressful life events (SLE) composed of four aspects of life during the previous year: personal, family, work and environment. The SLE was assessed through the total number and the weighted score. Contrary to the theory, the results showed that the SOC score has no intra-individual stability. The mean score of SOC in 1998 was 131.1 +/- 23.9, significantly lower than that in the previous year. When the subjects were divided into two groups based on a median 1997 score, the effect of SLE negatively affected SOC scores after one year among those who had a low SOC, although this effect was not observed among those who had a high SOC. The effect of SLE on changes of SOC was stronger among men compared to women. Also, the results showed the SOC was positively related to psychological health, and the buffering effect of SOC on the psychological health in dealing with stressful life events was only observed among men. Findings in this study suggest that SOC is variable for those with weak SOC if they experienced stressful life events. Also, the stressful life events differentially affect the SOC among men and women. The buffering effect was not sufficiently proven in this study. Methodological issues to confirm Antonovsky's theory are also presented.
