OBJECTIVE. The purpose of this study was to determine whether listening to a relaxation audiotape before and during mammography decreases subjective reports of pain and anxiety.

CONCLUSION. Listening to a relaxation or music audiotape before and during mammography does not reduce subjective reports of anxiety or pain. Women undergoing screening mammography report minimal levels of distress.

Despite the widespread availability of mammography, including access to free examinations for low-income women and portable mammography in rural areas, many women do not follow the accepted guidelines for mammography screening. According to the American Cancer Society, one third to one half of women do not follow screening guidelines. One of the most commonly reported reasons for this lack of adherence is the pain and anxiety associated with mammography. Most women who choose not to rescreen cite pain during the procedure as the primary reason [1]. Because anxiety is documented to be the most important contributor to procedural pain, interventions designed to reduce both physical and psychologic discomfort are needed. Although the discomfort associated with mammography has been noted for many years by patients and researchers alike, no intervention studies about patients undergoing mammography have been published to date.

Relaxation techniques have been used successfully in the treatment of numerous physical and psychologic disorders. Several studies support the efficacy of relaxation techniques in reducing pain and anxiety during radiologic procedures, including endoscopy, arteriography, and MRI [24]. If a simple, inexpensive, noninvasive intervention could decrease distress during mammography, not only would it benefit patients immediately, but also it is hypothesized that compliance with screening guidelines would increase if distress can be decreased. The goal of this study was to determine whether relaxation techniques reduce subjective distress during screening mammography.

This study was approved by the hospital institutional review board, and all subjects read and signed an informed consent form. Women who were scheduled for screening mammography at an outpatient screening mammography facility of a tertiary care teaching hospital from August through December 2002 were screened for inclusion in the study. Exclusion criteria included an inability to read and speak English, women who brought in their own audiotape player and planned to listen to an audiotape during mammography, those having taken pain or anxiety medication before their procedure, or those with a current psychiatric diagnosis. Women who have a history of breast cancer do not undergo screening, so they were not eligible for the study.

Materials
The measures included one demographic form, two self-report questionnaires, and a Likert scale. On the basis of the data provided by subjects on the demographic form, we assessed age, education, ethnic background, mammography history, family history of breast cancer, the reason for undergoing screening mammography, and experience with relaxation techniques. Information was not collected about a history of being recalled because of mammographic findings, a history of breast biopsy, or whether the subject had any friends with breast cancer.

The two self-report questionnaires were the Spielberger State Trait Anxiety Inventory (STAI) [5] and the McGill Pain Questionnaire (MPQ) [6]. Both of these questionnaires have been used extensively in intervention research, are easily completed in a few minutes, are reliable in an acute setting, and have been used in previous radiologic intervention research [3]. Subjects also completed a Likert scale to rate pain and anxiety. For each Likert scale, subjects were asked to mark the level of pain or anxiety they experienced during their mammography examination on a scale of 1 (no pain) to 10 (very painful) and 1 (not anxious) to 10 (very anxious), respectively.

Methods
Women were approached by one of the research assistants after they had changed into a gown and were sitting in the waiting room provided for screening mammography patients only. During the recruiting phase, each potential subject was asked if she would be interested in participating in a brief study to determine the effects of listening to an audiotape before and during mammography. Of the 280 women approached for potential recruitment, 88 declined to participate. Of the 192 who agreed to be screened for inclusion, 42 were found not to meet the eligibility criteria. Women who met the eligibility criteria had the purpose and procedures of the study explained to them and were asked to read and sign an informed consent form. They then completed the demographic form and the STAI. Six subjects withdrew consent before randomization for the following reasons: one was late for a meeting, one did not want to be in a control group, one stated that reading the questions made her "feel depressed," one changed her mind, one did not have enough time before being called in for the mammography examination, and one did not like the wording of the consent form. A seventh subject was not included in the data analysis because she later reported that she did indeed have a current psychiatric illness, thus making her ineligible.

Subjects were then randomized, according to a computer-generated random-numbers table, into one of three groups: relaxation, music, or control. All subjects were informed of their group assignment and were provided with an audiotape player and the appropriate audiotape. The relaxation audiotape contained information that led the subject through breath focus, body scan, and meditation. Breath focus involves focusing on the rhythm of the breath, body scan means to focus on different body parts as one inhales and to relax that body part as one exhales, and meditation means to focus on a neutral word or phrase in rhythm with one's breath. The music subjects had a choice of classical music, jazz, or soft rock. Control subjects listened to a blank tape.

Subjects were instructed to listen to their tape while sitting in the waiting room before and again during examination. They were asked to turn the volume lower during mammography so that they could hear the instructions of the technologist. All subjects were asked to not let the radiologic technologist know their group assignment. All subjects were told after imaging that they would not be receiving their mammography results that day. This change of hospital procedure within the past 1–2 years was based purely on staffing issues. Many of the patients would have been accustomed to receiving results immediately after mammography.

After undergoing mammography, each subject was met by the research assistant in the waiting room. They were asked to complete the STAI (State only), the MPQ, and the Likert scale. The STAI has two separate components: one is for trait anxiety and one is for state anxiety. They returned the audiotape player and tape and were thanked for participating in the study.

The analyses were performed first by comparing the patient characteristics among the three study arms to ensure randomization had created balance among the three groups. Chisquare tests were used to compare categoric patient characteristics, and the Kruskal-Wallis test was used to compare continuous characteristics. The Kruskal-Wallis test also was used for simple three-group comparisons of study outcomes between the randomized arms. For the STAI state scores, baseline scores were available for each woman and an adjusted linear regression model was constructed with baseline STAI state score as a continuous covariate and indicator variables for the treatment arms included as the primary predictors. Beyond the question of the efficacy of the intervention, further linear regression models were constructed to look for other predictors of the various study outcomes. Two-sided p values of less than 0.05 were considered statistically significant. Because no p value reached this level for the primary study hypotheses, no further corrections for multiple testing were warranted.

A total of 50 subjects were in the relaxation group, 47 in the music group, and 46 in the control group. As can be seen in Table 1, the groups were equivalent before randomization in terms of age, education, race, mammography history, and STAI scores.

TABLE 1 Baseline Patient Characteristics by Group

 

No significant differences among the groups on any of the assessed measures were noted (Table 2). However, the mean scores of both groups for all scores were surprisingly low. For example, the STAI scores before mammography did not differ from national norms of baseline anxiety. The Likert scores for both anxiety and pain during mammography were extremely low.

TABLE 2 Study Outcomes by Group

 

A multiple regression analysis using group, ethnicity, education, age, and mammography history showed few significant relationships. White women reported higher anxiety scores after mammography than women of other races, and older women had lower anxiety scores after mammography than younger women.

Contrary to expectations, subjects who listened to a relaxation audiotape before and during their screening mammography did not report any benefits from the intervention when compared with subjects who listened to music or a control group. The main reason no differences were detected appears to be a floor effect; the mean scores of all three groups for anxiety were low before, during, and after their screening examination. The mean scores for reported pain during the procedure were also low. There are a number of reasons why this may have been observed.

The study may have included a biased sample. Approximately one half of approached potential subjects refused participation. It is possible that the more anxious and distressed women excluded themselves and that the calmer women felt more able to listen to the purpose and procedures of the study. However, the opposite could have been true as well, and it would make sense for the most anxious women to seize the opportunity to participate in a "relaxation study."

Perhaps patients undergoing screening mammography actually experience low levels of pain and anxiety. Pain has been cited as the most commonly reported reason why women fail to return for repeat mammography screening [1]. However, the fear of pain, rather than the experience of pain, may be decreasing compliance with mammography screening. Recent research indicates that the mammography population frequently report anxiety and pain but that only a minority (10–15%) actually experience moderate or severe distress [7]. In a review of 10 studies about psychologic distress associated with organized breast cancer screening [8], researchers determined that anxiety is the most common issue, with the highest levels found in women with abnormal results. Indeed, much of the literature about distress associated with mammography has focused on women recalled because of abnormal findings on initial mammograms [911].

In this study, the mean levels of anxiety and pain reported by the subjects were very low—so low, in fact, that it would be difficult for any intervention to show an effect. The results of this study led to three future steps.

The first step was to design a similar study but one that evaluates a more distressed population, such as women who have been recalled for a repeat examination after having abnormal findings on a screening mammogram. Because this population has documented levels of distress, an intervention such as relaxation may have an effect on subjective reports of pain and anxiety and, as a result, on compliance with screening guidelines. The second step is to disseminate the information from this study. Perhaps if women learned that routine screening mammography is associated with low levels of anxiety and pain, their fear may subside enough to decide to comply with the screening guidelines. Finally, the subjects in this study are being followed up for 15 months after their screening mammography examinations to determine which factors, if any, determine their decision to undergo rescreening a year later. The results should be available in a year.
