Older residents (N 5 1972) in California were investigated prospectively for association of volunteering service to others and all-cause mortality. Potential confounding factors were studied: demographics, health status, physical functioning, health habits, social support, religious involvement, and emotional states. Possible interaction effects of volunteering with religious involvement and social support were also explored. Results showed that 31 percent (n 5 630) of respondents volunteered, about half (n5289) for more than one organization. High volunteers ([.greaterequal]2 organizations) had 63 percent lower mortality than nonvolunteers (age and sex-adjusted) with relative hazard (RH) 5 0.37, confidence interval (CI) 5 0.24, 0.58. Multivariate adjustment moderately reduced difference to 44 percent (RH 5 0.56, CI 5 0.35, 0.89), mostly due to physical functioning, health habits, and social support. Unexpectedly, volunteering was slightly more protective for those with high religious involvement and perceived social support. After multivariate adjustment, any level of volunteering reduced mortality by 60 percent among weekly attenders at religious services (RH 5 0.40; CI 5 0.21,0.74). Lower mortality rates for community service volunteers were only partly explained by health habits, physical functioning, religious attendance, and social support.

Objective and Participants: The authors evaluated the effects on stress, rumination, forgiveness, and hope of two 8-week, 90-min/wk training programs for college undergraduates in meditation-based stress-management tools. Methods: After a pretest, the authors randomly allocated college undergraduates to training in mindfulness-based stress reduction (MBSR; n = 15), Easwaran's Eight-Point Program (EPP; n = 14), or wait-list control (n = 15). The authors gathered pretest, posttest, and 8-week follow-up data on self-report outcome measures. Results: The authors observed no post-treatment differences between MBSR and EPP or between posttest and 8-week follow-up (p > .10). Compared with controls, treated participants (n = 29) demonstrated significant benefits for stress (p < .05, Cohen's d = -.45) and forgiveness (p < .05, d = .34) and marginal benefits for rumination (p < .10, d = -.34). Conclusions: Evidence suggests that meditation-based stress-management practices reduce stress and enhance forgiveness amon...

OBJECTIVES: This study analyzed the prospective association between attending religious services and all-cause mortality to determine whether the association is explainable by 6 confounding factors: demographics, health status, physical functioning, health habits, social functioning and support, and psychological state. METHODS: The association between self-reported religious attendance and subsequent mortality over 5 years for 1931 older residents of Marin County, California, was examined by proportional hazards regression. Interaction terms of religion with social support were used to explore whether other forms of social support could substitute for religion and diminish its protective effect. RESULTS: Persons who attended religious services had lower mortality than those who did not (age- and sex-adjusted relative hazard [RH] = 0.64; 95% confidence interval [CI] = 0.52, 0.78). Multivariate adjustment reduced this relationship only slightly (RH = 0.76; 95% CI = 0.62, 0.94), primarily by including physical functioning and social support. Contrary to hypothesis, religious attendance tended to be slightly more protective for those with high social support. CONCLUSIONS: Lower mortality rates for those who attend religious services are only partly explained by the 6 possible confounders listed above. Psychodynamic and other explanations need further investigation.

Objective: Frequent attendance at religious services has been reported by several studies to be independently associated with lower all-cause mortality. The present study aimed to clarify relationships between religious attendance and mortality by examining how associations of religious attendance with several specific causes of death may be explained by demographics, socioeconomic status, health status, health behaviors, and social connections. Method: Associations between frequent religious attendance and major types of cause-specific mortality between 1965 and 1996 were examined for 6545 residents of Alameda County, California. Sequential proportional hazards regressions were used to study survival time until mortality from circulatory, cancer, digestive, respiratory, or external causes. Results: After adjusting for age and sex, infrequent (never or less than weekly) attenders had significantly higher rates of circulatory, cancer, digestive, and respiratory mortality ( p < 0.05), but not mortality due to external causes. Differences in cancer mortality were explained by prior health status. Associations with other outcomes were weakened but not eliminated by including health behaviors and prior health status. In fully adjusted models, infrequent attenders had significantly or marginally significantly higher rates of death from circulatory (relative hazard [RH] = 1.21, 95 percent confidence interval [CI] = 1.02 to 1.45), digestive (RH = 1.99, p < 0.10, 95 percent CI = 0.98 to 4.03), and respiratory (RH = 1.66, p < 0.10, 95 percent CI = 0.92 to 3.02) mortality. Conclusions: These results are consistent with the view that religious involvement, like high socioeconomic status, is a general protective factor that promotes health through a variety of causal pathways. Further study is needed to determine whether the independent effects of religion are mediated by psychological states or other unknown factors.

The authors evaluated an 8-week, 2-hr per week training for physicians, nurses, chaplains, and other health professionals using nonsectarian, spiritually based self-management tools based on passage meditation (E. Easwaran, 1978/1991). Participants were randomized to intervention (n = 27) or waiting list (n = 31). Pretest, posttest, and 8- and 19-week follow-up data were gathered on 8 measures, including perceived stress, burnout, mental health, and psychological well-being. Aggregated across examinations, beneficial treatment effects were observed on stress (p = .0013) and mental health (p = .03). Treatment effects on stress were mediated by adherence to practices (p = .05). Stress reductions remained large at 19 weeks (84% of the pretest standard deviation, p = .006). Evidence suggests this program reduces stress and may enhance mental health.
