Consider Pearson’s correlation coefficient, \(r\), calculated from two variables \(X\) and \(Y\) with population correlation \(\rho\). If one calculates \(r\) from a simple random sample of \(N\) observations, then its sampling variance will be approximately
Religion and spirituality (R/S) are patient-centered factors and often are resources for managing the emotional sequelae of the cancer experience. Studies investigating the correlation between R/S (eg, beliefs, experiences, coping) and mental health …
Religion and spirituality (R/S) play an important role in the daily lives of many cancer patients. There has been great interest in determining whether R/S factors are related to clinically relevant health outcomes. In this meta-analytic review, the …
Although religion/spirituality (R/S) is important in its own right for many cancer patients, a large body of research has examined whether R/S is also associated with better physical health outcomes. This literature has been characterized by …
Meta-analyses of the relationship between 2 continuous variables sometimes involves conversions between different effect sizes, but methodological literature offers conflicting guidance about how to make such conversions. This article provides …
Several different approaches have been proposed for meta-analysis of correlation coefficients. One of the major differences between approaches is the choice of scale: whether effect sizes should be analyzed on the Pearson-r scale or first transformed to the Fisher-z scale.
