The Effect of Loving-Kindness Meditation on Flight Attendants’ Spirituality, Mindfulness and Subjective Well-Being

<i>Background</i>: This study investigated: (1) the effects of the loving-kindness meditation (LKM) on mindfulness, subjective well-being (SWB), and spirituality and (2) the relationships between mindfulness, spirituality, and SWB. <i>Methods</i>: 98 flight attendants from Xiamen Airlines in China were recruited and randomly assigned to the LKM training group (<i>n</i> = 49) or the waiting control group (<i>n</i> = 49). The LKM training group underwent an 8-week LKM training intervention, and the control group did not undergo intervention. The three main variables (SWB, mindfulness, and spirituality) were measured both before (pre-test) and after (post-test) the LKM training intervention. <i>Results</i>: In the experimental group, SWB and spirituality increased significantly. In the control group, no significant differences were observed for the three variables between the pre-test and post-test. <i>Conclusions</i>: Our results indicated that LKM may help to improve SWB and spirituality. However, the mechanisms which underlie the effects of the LKM on mindfulness, spirituality, SWB, and other psychological constructs require further elucidation.
