This study investigated changes in psychological and physiological markers during a weekend meditation workshop (N = 34). Psychological symptoms of anxiety, depression, posttraumatic stress disorder (PTSD) and happiness were assessed. Physiological markers included cortisol, salivary immunoglobulin A (SigA), heart rate variability (HRV), blood pressure (BP), and resting heart rate (RHR). On posttest, significant reductions were found in cortisol (-29%, P < .0001), RHR (-5%, P = .0281), and pain (-43%, P = .0022). Happiness increased significantly (+11%, P = .0159) while the increase in SigA was nonsignificant (+27%, P = .6964). Anxiety, depression, and PTSD all declined (-26%, P = .0159; -32%, P = .0197; -18%, P = .1533), though changes in PTSD did not reach statistical significance. No changes were found in BP, HRV, and heart coherence. Participants were assessed for psychological symptoms at 3-month follow-up, but the results were nonsignificant due to inadequate sample size (n = 17). EcoMeditation shows promise as a stress-reduction method.
本研究调查了在一个周末冥想工作坊期间（N = 34）心理和生理指标的变化。评估了焦虑、抑郁、创伤后应激障碍（PTSD）和幸福感的心理症状。生理指标包括皮质醇、唾液免疫球蛋白A（SigA）、心率变异性（HRV）、血压（BP）和静息心率（RHR）。在测试后，发现皮质醇（-29%，P <.0001）、RHR（-5%，P =.0281）和疼痛（-43%，P =.0022）有显著降低。幸福感显著增加（+11%，P =.0159），而SigA的增加不显著（+27%，P =.6964）。焦虑、抑郁和PTSD均有所下降（-26%，P =.0159；-32%，P =.0197；-18%，P =.1533），尽管PTSD的变化未达到统计学显著性。BP、HRV和心率相干性未发现变化。在3个月的随访中对参与者的心理症状进行了评估，但由于样本量不足（n = 17），结果不显著。生态冥想作为一种减压方法显示出前景。
