Mastery, sense of coherence, and mortality: Evidence of independent associations from the epic-norfolk prospective cohort study.

This study investigated the association between 2 distinct personal coping resources (mastery and sense of coherence) and all-cause, cardiovascular, and cancer mortality. During follow-up (up to 6 years), 994 deaths were recorded among 20,323 participants, ages 41 to 80 years, in the European Prospective Investigation into Cancer Study in the United Kingdom. A strong sense of mastery was associated with lower rates of mortality from all causes, cardiovascular disease, and cancer, after adjusting for age, sex, and prevalent chronic physical disease. The association with all-cause mortality was observed for both men and women and remained following further adjustment for cigarette smoking, social class, hostility, neuroticism, and extroversion. Analysis of the joint association between mastery and sense of coherence revealed both personal coping dispositions to be independently associated with lower rates of all-cause mortality. In addition, these data suggested that the association for mastery was specific to cardiovascular mortality, whereas the association for sense of coherence was specific to cancer mortality. These results may aid future study of coping resources as determinants of persistent well-being. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mastery is associated with cardiovascular disease mortality in men and women at apparently low risk.

Objective: We examine the prospective relationship between mastery, where limited mastery is defined as the inability to control negative emotions (and perceiving stressful experiences as beyond personal control), and cardiovascular disease (CVD) mortality particularly among individuals at apparently low CVD risk. Design: Prospective population-based study of 19,067 men and women, aged 41–80 years with no previous heart disease or stroke at baseline assessment. Main Outcome Measures: Primary outcome measure CVD mortality. Results: A total of 791 CVD deaths were recorded up to June 2009 during a median 11.3 person-years of follow-up. Limited perceived mastery over life circumstances was associated with an increased risk of CVD mortality, independently of biological, lifestyle, and socioeconomic risk factors (hazard ratio 1.11 per SD decrease in mastery score, 95% confidence interval 1.01–1.21). This association was more pronounced among those participants apparently at low CVD risk (p = .01 for test of interaction according to the number of CVD risk factors at baseline). Conclusions: Limited perceived control over life circumstances is associated with an increased risk of CVD mortality, independently of classical cardiovascular risk factors, and particularly among those at apparently low risk. Future attention should be given to this potentially modifiable personal characteristic, through the design of preliminary intervention studies, to reduce cardiovascular risk.
