Abstract
This study is a randomized single-blind trial, which aimed to evaluate the efficacy of true auriculotherapy and placebo auriculotherapy in reducing the stress levels of mid-level Nursing students of the School of Nursing of the Beneficência Portuguesa Hospital. Seventy-one students with average, high and very high scores, according to Vasconcellos' List of Stress Symptoms, were divided into three groups: Control (25), Auriculotherapy (24), and Placebo/Sham (22). They were evaluated at the baseline, 8th and 12th sessions and at the follow-up (15 days) and received Shen Men and Brainstem points (Auriculotherapy Group) and Wrist and Outer Ear points (Placebo/Sham Group). The analysis of variance (ANOVA) showed statistically significant differences between the Control/Auriculotherapy groups from the 8th session, which was maintained in the third and fourth evaluations (p=0.000) and between the Control/Placebo groups (p<0.05) at the three evaluations. It was concluded that the true auriculotherapy obtained better responses (45.39%) than the placebo (34.18%) in the reduction of the stress, but further studies are recommended for the re-evaluation of the sham points for stress. ClinicalTrials.gov Identifier: NCT01420848.
Highlights
Stress is a process that can be experienced either positively or negatively by an individual
Data analysis and hypotheses testing: For the inferential analysis a statistical test was performed, where the hypothesis to be tested was that there was no significant difference between the differences of the means obtained between the three groups
Regarding the result of the analysis of variance (ANOVA) test for repeated measures, a statistical difference was found between the differences of the means of the groups at the three times, when compared between LSS2/LSS1 (p=0.000), LSS3/ LSS1 (p=0.000) and LSS4/LSS1 (p=0.000)
Summary
Stress is a process that can be experienced either positively or negatively by an individual. Selye first used the term stress in the area of health in 1936 to define a set of physiological reactions that the body develops when faced with a situation of stress, triggered by homeostasis threatening stimulation, generating diverse symptoms(1). This set of physical, chemical, biological or psychosocial non-specific reactions are know as the “General Adaptation Syndrome” which consists of three successive phases: Alarm Phase, Adaptation or Resistance and Exhaustion Phase(2).
