Introduction

The physical, mental and psychic well-being can impact significantly in the results and productivity of the worker, especially those that deal with health, and work in a high stress environment, such as a hospital(1). There is consensus that psychological and social factors can cause problems in the health of individuals and that the Coping strategies in situations of stress may be determinants of the mental, physical and social health(2). The structural work conditions of health professionals, often poorly paid, little encouraged and subject to a considerable overload of activities, hinder the possibility of performing humanized care, since the humanizing process begins with the humanization of the production of this care(3).

It is noteworthy, therefore, that to care for professionals who provide healthcare services can be a key strategy, since good results in the care mainly depend on healthy work teams, especially considering that nurses deal with conflicts and errors in the vertical and horizontal relationships between professionals, family members and patients on a daily basis.

Attention has focused on Coping with stress and instruments have been developed to evaluate how people cope with difficulties or stressful circumstances in their lives. In this context Coping emerges as a more elaborate, adaptive, flexible and conscious response to a given stressor element. The Coping concept differs from concept of the defense mechanism in stress situations, because the responses obtained in this mechanism are classified as rigid, inadequate in relation to the external reality and may originate from past issues and elements of the unconscious(4). Conversely, a Coping response is an intentional, physical or mental action, initiated in response to a perceived stressor, directed toward the external circumstances or internal states, with this response guided by attempting to reduce the stress(5).

Eastern cultures have historically developed strategies for coping with stress from bodily practices, exercises, movements, dances and massage, aiming to preserve and restore health, to flexibility and strengthening of the body and mind(6). The benefit of such practices in the maintenance of quality of life was the main motivation to perform this study. There are numerous types of alternative therapies and bodily practices, some of them ancient, which seek to cure diseases and increase well-being, as in acupuncture, herbal medicine and massage, and to attain spiritual balance and harmony, as is the case for tai chi chuan, yoga and meditation(7).

Chinese auriculotherapy is a Traditional Chinese Medicine practice and is a method that uses specific points on the ear to treat various disorders of the body(8). Auriculotherapy is indicated for the treatment of many disorders: pain, inflammation, endocrine metabolic and urogenital system problems, disorders of a functional nature, chronic and infectious-contagious diseases, etc. It is indicated in cases where the patient has a need for immediate pain relief, or when they have stinging, acute and chronic pains, mental disorders, such as anxiety and depression, distress, lack of concentration, dizziness, stuttering, disorders of the autonomic system, or intoxication from drug, tobacco and medication use. Conventionally, auricular acupuncture employs semi-permanent or systemic needles as instruments to stimulate the points(9). Seeds or magnets can also be utilized to perform the stimulation(10).

The mechanism of action of auriculotherapy has been discussed and it is speculated that the technique works because groups of pluripotent cells contain information about the whole organism and create regional centers of organization that represent different parts of the body. When the reflex points in the ear are stimulated the relief of symptoms in distant parts of the body can be achieved(9). Stimulating points can also activate small myelinated nerve fibers that send impulses to the spinal column, brain, pituitary and hypothalamus, causing the release of endorphins into the blood in the treatment of pain(11).

Regarding the ethical-legal aspects of the practice of acupuncture, the Federal Nursing Council established in Resolution 197/97 that various complementary practices, among them acupuncture, are specialties of the nurse(12). Furthermore, from 2006, Regulation No. 971, of May 3rd, 2006, approved the National Policy on Integrative and Complementary Practices (PNPIC), which defined acupuncture as a multidisciplinary practice, i.e., as a specialty of all categories of higher level healthcare professionals, guaranteeing the practice of the acupuncturist nurse(13).

From these previous reflections, it was questioned whether auriculotherapy would be useful for diminishing the stress levels of the Nursing team and whether it would have the therapeutic reach of, by itself, modifying the coping of stress, with significant changes in Coping domains according to the questionnaire of Folkman and Lazarus.

Aims

The aims of this study were to evaluate the efficacy of auriculotherapy with needles and seeds in reducing the stress levels of the nursing team employees of a hospital, and to identify and analyze differences between before and after the treatment in the Coping domains according to the questionnaire of Folkman and Lazarus.

Materials and Method

Study Type: This is a Randomized Controlled Clinical Trial with 3 groups: a control group (no intervention) and two intervention groups (auriculotherapy with needles and auriculotherapy with seeds).

Ethical and legal aspects: The research was conducted in a teaching hospital in São Paulo. The study followed Resolution 196/1996 of the National Health Council, regarding the involvement of human beings in the research. The research project was accepted by the Research Ethics Committee with registration No. 941/09-SISNEP CAAE: 0060.0.198.000-09. The participants of the Control Group were given the opportunity to, after study, be treated for the same period and for free with one of the auriculotherapy techniques used in the study.

Sample: To define the sample of participants the Inventory about the Stress State or Vasconcellos' List of Stress Symptoms - LSS was used(14). This instrument was applied with all those who expressed interest in participating in the study (109), however, only those individuals who attained medium, high or very high scores were invited to participate; 75 of them managed to complete the study.

The allocation of the participants was performed through the distribution of opaque envelopes, containing a number and sealed. Numbers were then randomly generated and allocated to the three groups using the website www.randomizer.org. Of the 75 who completed the study, 22 subjects were in the Control Group, 27 in the Needle Group and 26 in the Seed Group. From the sample calculation, it could be affirmed that the sample had a test power of 80% for a significance level of 5%, or confidence level of 95%.

Inclusion criteria were: voluntary participation in the study with time available to commit to the sessions, achieving medium and high level scores in the LSS, not suffering from kidney stones with surgical indication and not being pregnant. Subjects were excluded for various reasons, explained in the fluctuation of subjects diagram (Figure 1). Due to "other reasons" those who did not attend the first session and some non-nursing professionals were excluded.


Data Collection: The List of Stress Symptom (LSS), a questionnaire with socio-demographic data and the Folkman and Lazarus' Ways of Coping questionnaire(15) were used to collect the data. This was carried out between January and July 2010 in a consulting room at the hospital. The instruments were applied by nurses, two with experience in auriculotherapy and four of them, prepared only for performing the study. In the LSS, with 60 items, the frequency with which the symptoms occur is indicated, from a scale of 4 response options: (0) never, (1) rarely, (2) often, and (3) always. The total score of this inventory can vary from 0 to 177 points, with scores representing the stress levels of: absente (0 to 11 points), low level (12 to 28), medium level (29 to 60), high level (61 to 120) and extremely high level (over 120 points). Regarding the Ways of Coping questionnaire, it contains 66 items, encompassing thoughts and actions that people use to deal with the internal or external demands of a stressful event. The questions are scored using a Likert type scale, where 0 = not used; 1 = used somewhat; 2 = used quite a bit; 3 = used a great deal. The scale consists of 8 different "domains" suggested by the factorial analysis: confrontive coping, distancing, self-controlling, seeking social support, accepting responsibility, escape-avoidance, planful problem-solving and positive reappraisal.

The LSS and Ways of Coping questionnaire were applied before the treatment at the beginning of the study, after 4 sessions, after 8 sessions and 15 days after the termination. The intervention groups received 8 sessions (1 per week), lasting 5 to 10 minutes each, in the Shen Men, Kidney and Brainstem points. The Shen Men and Brainstem points have calming properties and the Kidney has an energy function(8). For the auriculotherapy with semi-permanent needles, after proper localization of the reactive points, cleaning with cotton wool and 70% ethyl alcohol was performed on the pinna and the needles were applied and affixed with micropore tape. For the group of auriculotherapy with seeds, mustard seeds were used and the subjects were instructed to stimulate the seeds three times a day, for fifteen days, using moderate pressure. It was suggested that the needles be withdrawn 24 hours before the consultation or if there was discomfort, pruritus or signs of allergy.


Statistical analysis of data: For the statistical analysis, the following parametric tests were used, ANOVA for repeated measures, after Levene's test and the Kolmogorov-Smirnov test. The Bonferroni Post Hoc test was carried out for stress levels among the three groups at four moments in time. For the analysis of the domains of the Ways of Coping questionnaire, homogeneity was observed for the Mauchly's sphericity test and ANOVA with Tukey's Post Hoc test was performed. The MS Excel program (2007) was used for the tabulation of the data and the statistical program SPSS 17.0.

Results

Of the 75 professionals, 12 were auxiliary nurses, 49 were nursing technicians and 14 nurses; 44 of them, representing 58.7%, presented scores related to medium levels of stress and 31 (41.3%) presented scores related to high levels. The ages of the subjects ranged between 39 to 45 years and the employees were from various sectors of the Hospital. According to the results in Table 1, it can be observed from the significance level (p<0.05), that there was homogeneity between the groups regarding age, length of employment and initial LSS. Regarding gender, there was a predominance of females (71), who corresponded to 94.6% of the sample, with homogeneous distribution between the groups of the few men (4) who participated in the study (p=0.65).

In the descriptive analysis of the domains found in Folkman and Lazarus' Ways of Coping questionnaire the following scores were obtained at the first evaluation: Confrontive Coping domain (mean: 5.97), Distancing (mean: 5.81), Self-Controlling (mean: 7.72), Seeking Social Support (mean: 8.96), Accepting Responsibility (mean: 8.99), Escape-Avoidance (mean: 3.12) and Planful Problem Solving domain (mean: 6.24). The scores for all items corresponded to - this strategy was "used quite a bit", with the exception of the Positive Reappraisal domain (mean: 15.05), where a score was obtained corresponding to "used a great deal".

Concerning the stress levels (Table 1), statistically significant differences were verified in the ANOVA for repeated measures, when comparing the three groups, at 4 different moments (LSS1, LSS2, LSS3, LSS4). The significance level between the differences in the results according to the Bonferroni test was p=0.020 between LSS3 and LSS1 and p=0.003 when comparing LSS4 and LSS1. The Seed Group showed no statistically significant differences regarding stress levels, when comparisons were performed between the groups at the four times, although positive results were obtained when compared within the same group, over time, with a significance level of p<0.05 .

Regarding the domains of Folkman and Lazarus' Ways of Coping questionnaire, the only domain that presented a statistically significant difference in the analysis between groups was Distancing, with p=0.039, as shown in Figure 3 below.


In the Distancing domain there was a change, from the initial mean obtained at the first evaluation (5.77) to the final mean at the fourth evaluation (6.65), which is to say that there was a change of level from "not used or used these strategies somewhat" to "used quite a bit". When an analysis of the domains within the same group was performed, a statistically significant difference was observed in the Confrontive Coping and Seeking Social Support domains, with a significance of p=0.029, for the Confrontive Coping domain between the first and fourth evaluation in the Needle Group and in the Seeking Social Support domain, between the first and third evaluation (p=0.022) in the Seed Group.

In Table 2, the mean scores of the domains at the four moments and the main factors and scores involved.

Discussion

There was a decrease in stress levels for the Needle Group from the third evaluation, confirming the efficacy of the auriculotherapy for the treatment of stress. For Traditional Chinese Medicine (TCM), by balancing energy aspects through the stimulation of points in the body or in microsystems, such as the ear, favorable conditions are provided for there to be a change in the social, emotional, physical, mental and spiritual behavior patterns of the individual(15). Auriculotherapy, as one of the techniques used in TCM, has been widely employed for the control of anxiety and psychological problems, as it promotes relaxation(16-17).

Although studies were found regarding the decrease in anxiety and stress from the use of auriculotherapy(18-19), no studies were found on the applicability of this technique for Coping and dealing with stress.

In the present study, Positive Reappraisal was found to be the main Coping strategy domain, in which the score corresponded to "used a great deal", suggesting that the nursing staff of this hospital used emotion-focused Coping in their quotidian. Similar result was obtained in the study carried out on Coping strategies among Oncology nurses, whose highest scoring domain was also that of Positive Reappraisal(5).

Emotion-focused Coping is an attempt to regulate the emotional state, directed towards a somatic level and/or a level of emotions, usable in situations where there is no possibility of change, where problems may be structural and external to the personal action. Folkman and Lazarus proposed this Coping model, the situational approach of which divides Coping in two functional categories: Problem-focused and emotion-focused coping. Problem-focused Coping is an attempt to act on the situation, trying to modify it, and can be internally or externally directed. Generally such Coping tends to be used in situations previously evaluated as modifiable. Studies indicate that both strategies are used during practically all stressful episodes and that the use of one or other may vary in efficacy, depending on the different types of stressors involved(20).

There are two ways to approach Coping styles. The structural model that relates styles to personality traits, and the situational approach, which considers the strategies that refer to thoughts and actions taken in the course of a stressful event. The situational approach has been emphasized, since the way each individual faces stress can be determined by several factors, such as environmental(21) and sociocultural aspects(22), age(23) and gender(24).

The domains that presented statistically significant differences were Distancing, Confrontive Coping and Seeking Social Support. Distancing corresponds to a strategy that involves denying the feeling of fear or anxiety arising from a stressful situation. In this strategy, the individual tries to forget the truth, refusing to believe that the situation is actually happening(25). There was an increase in the scores in this domain in the Control Group, justifying the statistical differences found.

Conversely, the domains Confrontive Coping and Seeking Social Support can be considered problem-focused Coping strategies. In the Confrontive Coping domain strategies are found that include the view of defiance and attention to one aspect of the situation. In both the group that was treated with seeds as well as the one treated with needles there were decreases in these means and, conversely, increases in the means of the Control Group. The Seeking Social Support domain includes strategies that seek assistance to help resolve the problem. Some possibilities could be: to look for friends, relatives and to ask for advice, to talk with other specific people looking for data regarding the situation, to speak with someone who could do something concrete about the problem, to seek professional help and to accept the comprehension of the people(25). In this domain, there was a decrease in the means in the Seed Group, however, not sufficient to modify the score "used quite a bit". The Control Group, however, achieved the score "used a great deal" in the third and fourth evaluations.

The results suggested that external stressful situations occurred during the study period, justified by the significant increase in the scores of the Control Group in the domains Distancing, Confrontive Coping and Seeking Social Support, whereas in the intervention groups, the people made less use of these strategies. The main limitation of the study was that no survey of these stress factors was performed. Furthermore, not delineating the variables that presented uniformity regarding the problems experienced hindered further analysis of the effects of the auriculotherapy on the Coping strategies. Further studies are suggested in order to investigate how auriculotherapy can modify these strategies and patterns of behavior.

Conclusions

Of the 75 participants, 44 (58.7%) presented medium level of stress and 31 (41.3%) presented high levels. The main Coping domain found in the Nursing team according to Folkman and Lazarus' inventory was Positive Reappraisal. The auriculotherapy treatment was positive for decreased levels of stress in the Nursing team, with better results for semi-permanent needles than for seeds. There was a decrease in the use of the Distancing, Confrontive Coping and Seeking Social Support domains for the intervention groups after the treatment, suggesting that auriculotherapy, both with needles and seeds, can produce a positive impact to improve the Coping strategy in the Nursing team. Further studies, however, are necessary in order for the scope of the technique to be ascertained.
