:''For a general discussion of the philosophical and religious issues, please see Efficacy of prayer''. Some religions claim that praying for somebody who is sick can have positive effects on the health of the person being prayed for. Meta-studies of the literature in the field have been performed showing evidence only for no effect or a potentially small effect. For instance, a 2006 meta analysis on 14 studies concluded that there is "no discernible effect" while a 2007 systemic review of intercessory prayer reported inconclusive results, noting that 7 of 17 studies had "small, but significant, effect sizes" but the review noted that the most methodologically rigorous studies failed to produce significant findings.〔〔 ==Introduction== In comparison to other fields that have been scientifically studied, carefully monitored studies of prayer are relatively few. The field remains tiny, with about $5 million spent worldwide on such research. If and when more studies of prayer are done, the issue of prayer's efficacy may be further clarified.〔Boorstein, Michelle. (Researchers Stepping Up Study of Health And Religiosity ), ''Washington Post'', 6 December 2008.〕 The third party studies discussed here have all been performed using Christian prayers. Some have reported null results, some have reported correlations between prayer and health, and some have reported contradictory results in which beneficiaries of prayer had worsened health outcomes. The parameters used within the study designs have varied, for instance, daily or weekly prayers, whether to provide patient photographs, with full or partial names, measuring levels of belief in prayer, and whether patients underwent surgery. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「studies on intercessory prayer」の詳細全文を読む スポンサード リンク
