The associations among the dispositional mindfulness, COVID-19 burnout, and life satisfaction has been examined in cross-sectional studies. However, the fact that these variables were not considered together in any longitudinal research created a gap in the literature. The present study used a longitudinal design to examine whether COVID-19 burnout mediated the association between dispositional mindfulness and life satisfaction in a Turkish sample. In order to overcome the severe limitations of examining mediation with cross-sectional data, an autoregressive analysis of cross-lagged panel model for a half-longitudinal design was used to test the mediating role of COVID-19 burnout in the relationship between dispositional mindfulness and life satisfaction. In this cross-lagged panel model, data were collected at two time points at three-month intervals. The results indicated that COVID-19 burnout has a longitudinal mediating role in the relationship between dispositional mindfulness and life satisfaction (χ²_{(27, N = 263)} = 140.96, p < .001; SRMR = 0.033; CFI = 0.95, TLI = 0.92, NFI = 0.94, IFI = 0.95). Current findings highlight that focusing individuals on the present during the pandemic is a powerful tool to protect their mental health.

横断面研究已经检验了性格正念、COVID-19 倦怠和生活满意度之间的关联。然而，在任何纵向研究中，这些变量都没有被一起考虑，这一事实在文献中造成了空白。本研究采用纵向设计来检验土耳其样本中 COVID-19 倦怠是否介导性格正念与生活满意度之间的关联。为了克服用横截面数据检查中介的严重局限性，采用半纵向设计的交叉滞后面板模型的自回归分析来测试COVID-19倦怠在性格正念与生活满意度。在这个交叉滞后面板模型中，每隔三个月在两个时间点收集数据。结果表明，COVID-19倦怠在性格正念与生活满意度之间的关系中具有纵向中介作用（χ² _{(27，N = 263)}  = 140.96，p  < .001；SRMR=0.033；CFI = 0.95，TLI = 0.92，NFI = 0.94，IFI = 0.95）。目前的研究结果强调，在大流行期间让个人关注当下是保护他们心理健康的有力工具。
