Recent years have witnessed increased interest in the relationship between positive psychological well-being and physical health. Methods: We searched general bibliographic databases: Medline, PsycINFO, Web of Science, and PubMed up to January 2008.

The meta-analyses showed that positive psychological well-being was associated with reduced mortality in both the healthy population (combined hazard ratio (HR) 
 0.82; 95% Confidence Interval (CI) 0.76–0.89; p  .001) and the disease population (combined HR 
 0.98; CI 
 0.95–1.00; p 
 .030) studies. There were indications of publication bias in this literature, although the fail-safe numbers were 2444 and 1397 for healthy and disease population studies, respectively. Intriguingly, meta-analysis of studies that controlled for negative affect showed that the protective effects of positive psychological well-being were independent of negative affect. Both
