Efficacy of a brief oMBI

Pre-post design quantitative research on HCPs and those in training who participated in the 4-week oMBI displayed positive effects on self-report measures such as MAAS which is usually indicative of being more present and not being in the state of ‘auto pilot’. The mean increased from 3,5 to 3,9 with a p-value of,0.001 as seen in Table 2 above. There was a significant decrease in the PSS and subsequent negative emotions related to this post oMBI. Both pre and post means of the PSS fell in the moderate range, but the change in scores was significant, dropping from a mean of 21,1 to 15,26 with a p-value of &lt; 0.001. The abbreviated Maslach Burnout Inventory, as mentioned, has three subscales to measure burnout, EE, D and PA. A decrease in EE and D would indicate reduced burnout, as is seen in the results. EE reduced from a mean of 10,3 to 8, 89, which was a significant finding with a p-value of 0.04. The means of D and PA could not be calculated due to the skewed distributions and outliers' presence; thus, the interquartile range (IQR) and median were used instead. D reduced from a median of 2 to 1 post oMBI, however these findings were not significant. The PA scores did increase significantly from a median of 15 to 16 with a p value of &lt; 0.002, alluding to increased competence and ability to make a meaningful difference through their work.本研究针对参与4周oMBI的医疗保健专业人员（Healthcare Professionals, HCPs）及其受训人员开展前后测定量研究，结果显示该干预在自我报告量表中展现出积极效果：以正念注意觉知量表（Mindful Attention Awareness Scale, MAAS）为例，该量表常用于评估个体是否更处于当下觉知状态，而非处于“自动驾驶”的无意识行为模式中，其平均分从3.5提升至3.9，p值为0.001，相关结果详见上表2。干预后，知觉压力量表（Perceived Stress Scale, PSS）得分及与之相关的负面情绪均出现显著下降；干预前后PSS的平均分均处于中度压力区间，但得分变化具有统计学显著性，平均分从21.1降至15.26，p值小于0.001。如前文所述，简化版马氏倦怠量表（Maslach Burnout Inventory, MBI）包含三个用于评估倦怠的子维度，即情绪衰竭（Emotional Exhaustion, EE）、去人格化（Depersonalization, D）与个人成就感降低（Personal Accomplishment, PA）；情绪衰竭与去人格化得分降低意味着倦怠程度减轻，本研究结果亦印证了这一点：情绪衰竭的平均分从10.3降至8.89，该结果具有统计学显著性（p=0.04）。由于去人格化与个人成就感降低的得分分布呈偏态且存在异常值，故无法计算其平均分，转而采用四分位距（Interquartile Range, IQR）与中位数进行统计描述：干预后，去人格化的中位数从2降至1，但该变化未达到统计学显著性水平；个人成就感降低的中位数则从15显著提升至16（p<0.002），这表明从业者的工作胜任力与通过工作创造积极影响的能力有所增强。
