ABSTRACT

The present study investigated the meta-analytic association between dispositional optimism and telomere length. The meta-analysis included 12 samples and a total of 13,439 participants. A small weighted meta-analytic effect size, r =.06, p =.02, indicated that across samples greater optimism was associated with longer telomeres. A meta-analytic moderator analysis indicated that samples that included participants in stressful circumstances had a stronger association between optimism and telomere length, Q(1) = 7.47, p =.006. The results point to the need for research to identify the connections between optimism, stress, and telomere length.

摘要

本研究调查了性格乐观与端粒长度之间的元分析关联。荟萃分析包括 12 个样本和总共 13,439 名参与者。一个小的加权元分析效应大小，r =.06，p =.02，表明在样本中更大的乐观与更长的端粒有关。元分析主持人分析表明，包括处于压力环境中的参与者的样本在乐观和端粒长度之间具有更强的关联，Q(1) = 7.47，p =.006。结果表明需要进行研究以确定乐观、压力和端粒长度之间的联系。
