OBJECTIVE
To analyze the effects of flower essence bouquets on the signs and symptoms of stress in nursing students.
METHOD
Randomized clinical trial, triple blind, with two groups, flower essence group and placebo group, carried out with 101 nursing students. The groups used the formula for 60 days at a dosage of 4 drops 4 times a day. The outcome was evaluated using the Baccaro Test and the Perceived Stress Scale applied at the beginning and at the end of the intervention. The outcome analysis was performed using the mixed effects model, with 〈 = 5% and the effect size verified by the Cohen's d test.
RESULTS
There was no significant difference between the groups in stress reduction (p > 0.05). Both groups showed a reduction in scale scores (p < 0.001) with large effect size. There was an influence of the COVID-19 pandemic in the reduction of Baccaro Test scores.
CONCLUSION
The intervention with flower essence therapy was not more effective than placebo in reducing stress signs and symptoms. Brazilian Registry of Clinical Trials: UTN U1111-1257-5715.
目的
分析花精组合对护生应激症状和体征的影响。
方法
采用随机临床试验、三盲法，设花精组和安慰剂组，共纳入 101 名护生。两组均采用 60 天的疗程，剂量为每天 4 次，每次 4 滴。采用 Baccaro 测试和压力知觉量表（Perceived Stress Scale）在干预开始和结束时评估结果。采用混合效应模型进行结局分析，检验水准〈=0.05，用 Cohen's d 检验检验效应量。
结果
两组在减轻压力方面无统计学差异（p＞0.05）。两组量表评分均降低（p＜0.001），效应量较大。COVID-19 大流行对 Baccaro 测试评分的降低有影响。
结论
花精疗法干预与安慰剂相比，减轻应激症状和体征的效果并不更优。巴西临床试验注册处：UTN U1111-1257-5715。
