Research was reviewed on whether self-report measures of religiosity were a protective factor against suicidal behaviors. It was found that scores on Francis's measure of religiosity was negatively associated with non-lethal suicidal behavior (ideation and attempts), a protective effect. Similarly, it was found that intrinsic religiosity (but not extrinsic religiosity) was negatively associated with non-lethal suicidal behaviors. However, these associations were weak. Research is needed on the issue whether counselors can use their patients' religiosity to reduce the risk of dying by suicide.
Keywords: religiosity; suicidal ideation; attempted suicideThe association of religion and suicide has long been of interest. Durkheim (1897) noted and tried to explain the fact that Protestants have higher suicide rates than Roman Catholics, while it has long been known that Muslims have lower suicide rates than Christians (Lester 2006). There has been a great deal of research and theorizing about the role of religion, religiosity, and spirituality in increasing the risk of suicidal behavior versus acting as a protective factor for suicidal behavior. 1 In a meta-analysis of nine studies, Wu et al. (2015) found significant protective effects of religion (as measured by church/temple attendance or claiming/practicing a religion) on completed suicide. This effect was found to be stronger in studies conducted in Western cultures, in areas with high religious homogeneity, and among older populations. Sisask et al. (2010) also reported cross-cultural differences in the protective effects of three dimensions of religiosity (religious denomination, subjective religiosity, and organizational religiosity) for attempted suicide. The strongest protective effect across the different study sites, such as Brazil, Estonia, the Islamic Republic of Iran, and Sri Lanka, was found for subjective religiosity, that is, considering oneself to be a religious person, while the results for the more objective indicators of religiosity were mixed. The present chapter focuses on the association between religiosity and suicidal behavior in individuals. Since the research on this association involves self-report questionnaires, 2 the suicidal behavior is limited to suicidal ideation and, occasionally attempted suicide. Furthermore, we will focus more on our own research, but not to the exclusion of the research of others.
