Premenstrual syndrome refers to a group of physical and behavioral symptoms that occur periodically in the second half of the menstrual cycle
[1]. These symptoms are often associated with mood swings, breast tenderness, extreme fatigue, bad temper, depression, and cravings for foods, especially sweet foods
[2]. It is estimated that three out of four women who experience menstruation suffer from this syndrome
. Some females develop this syndrome at the age of 20 years, while others encounter this complication in their late 30s and 40s
[3]. This syndrome usually appears in a permanent and predictable pattern
. In some months, the symptoms may be very severe, and at other times, they are normal or even difficult to diagnose
[4].
Premenstrual syndrome is often associated with anxiety symptoms and even anxiety disorders that can be debilitating
. Therefore, most women with premenstrual syndrome suffer from anxiety, and this has been the case in various studies
[5]. Chompalova et al.
[6] showed that most women with premenstrual syndrome in Bulgaria suffered from anxiety and stress
. In a study on students, Choi, Lee, and Ahan
[7] found that anxiety levels in the premenstrual period and the induced boredom were associated with students' perfectionism
.
Depression is a common symptom in females with premenstrual syndrome
. However, it is important
to distinguish between underlying depression
(which often worsens before menstruation) and premenstrual syndrome or premenstrual disorder since their treatment is quite different
[8]. Women with underlying depression often feel better during or after menstruation; however, their symptoms do not disappear completely. On the other hand, at the onset of menstruation, these symptoms are eliminated in women with premenstrual syndrome or disorder
[9]. Women may think that they have a premenstrual syndrome or premenstrual disorder; nonetheless, they are depressed or anxious
[10].
There have been several studies on depression and premenstrual syndrome, which can be mentioned in this regard. According to a study conducted by Erbil
[11], it was found that the relationship between premenstrual syndrome symptoms and depression depended on the socioeconomic status of women. In another study, Forrester-Knauss, Zemp Stutz, and Weiss
[12] found that premenstrual syndrome could exacerbate depression in females with a history of deep depression
.
One of the traditional methods of relieving psychological pain is music therapy
. The use of music as a method of treatment has a long history. In ancient Egyptian, Greek, Chinese, Indian, and Roman inscriptions, music was mentioned as a healing instrument
[13]. In general, there are two types of music therapy, namely active and inactive depending on the type of the participants' reactions. Active music therapy includes singing, playing, or composing. On the other hand, listening to music is regarded as an inactive type of music therapy. This type of music therapy can include listening to the recorded or live music
. It is of significant importance that the participants in a study show their satisfaction with the music in the inactive type of music therapy
[14].
According to various studies, music therapy, as psychological treatment, has affected premenstrual symptoms
. Abdullahi, Sharifnejad, Hosseinpour, and Samiei
[15] revealed that music therapy was effective in the symptoms of premenstrual syndrome
. Similarly, Zadbagher Seighalani, Birshak, Hashemian, and Mir Hashemi
[16] indicated that traditional music therapy affected anxiety, depression, and physical aggression in females with premenstrual symptoms
. In the same line, Küçükkelepçe and Taşhan
[17] concluded in a study that people who underwent music-therapy intervention looked happier and calmer, compared to the control group
.
Objectives
This study aimed to investigate the role of music therapy in reducing anxiety and depression in premenstrual syndrome.
Materials and Methods
This applied study was conducted based on a quasi-experimental method using a pretest-posttest design with a control group. The study population included women with the premenstrual syndrome who were referred to a midwifery office in Tehran, Iran, in the first six months of 2019. In total, 30 females were selected voluntarily. The sample size was estimated at 12 cases based on Cohen's formula, the first and second types of errors, and expected average difference in the study groups. The participants were then divided randomly into the experimental (music therapy) and control groups consisting of 15 cases per group regarding the sample size and attrition, as well as the methodology of the study.
The inclusion criteria were the fulfillment of the following three conditions for women based on the Premenstrual Syndrome Screening Questionnaire
:1) From options 1 to 4, at least one case is moderate or severe, 2) In addition to the previous case, from options 1 to 14, four cases must be at least medium or severe, and 3) In the section of the effect of symptoms on life, there should be a moderate or severe case (the last five options). Another prerequisite for the diagnosis of premenstrual syndrome by obstetricians is in the second place.
Accordingly, 15 women diagnosed with premenstrual syndrome completed the pre-menstrual screening questionnaire, as well as Beck's Anxiety and Depression Tests. The experimental group was requested to participate in 12 sessions to listen to the selected music pieces for depression and anxiety at the intervention sessions and home (home assignment)
. Subsequently, the participants performed activities after listening to a piece of music in each intervention session. These activities included discussion on the music, making music with mouth sounds (without listening to that song simultaneously), and the effects that songs have on them. The participants completed the questionnaires again after the end of the music therapy sessions.
The research procedure and objectives were explained to all participants, and written informed consent was obtained from them. Moreover, regarding the ethical considerations, they were assured of the confidentiality of their information. The data were collected using the following tools:
Premenstrual symptom screening questionnaire
This 19-item questionnaire consists of two sections, the first of which includes 14 items to evaluate mood, as well as physical and behavioral symptoms. The second part measures the impact of these symptoms on people's lives using five items
. The items are rated based on a 4-point Likert scale of 0=not at all, 1=mild, 2=moderate, and 3=severe.
The following three conditions must be met for the diagnosis of moderate or severe premenstrual syndrome
: 1) From options 1 to 4, at least one case should be moderate or severe, 2) In addition to the previous case, from options 1 to 14, at least four cases should be moderate or severe, and 3) In the section of the effect of symptoms on life, there should be a moderate or severe case (the last five items).
The reliability of this scale was estimated at 0.90 using Cronbach's alpha coefficient in a study conducted by Siahbazi, Hariri, Montazeri, and Moghaddam Banaim in Iran
[18]. Moreover, the content validity ratio and index were estimated at 0.70 and 0.80, respectively, which confirmed the content validity of this questionnaire
. Additionally, the internal consistency of the premenstrual symptom screening questionnaire was obtained at 0.84 using a Cronbach's alpha coefficient in this study.
Back's Depression Test
The signs and symptoms of depression in this 5-item test include A) pessimism, feelings of failure, self-loathing, suicidal thoughts, indecision, and slowness of activities, B) feelings of guilt, as well as the expectation of punishment and blame, C) crying, changing one's self-image, dissatisfaction, and sadness, and D) weight loss, physical complaint, fatigue, premature ejaculation, insomnia, and anorexia
[19]. Furthermore, this scale assesses a wide range of symptoms and 21 aspects of depression
. Each dimension is rated using scores from 0 to 3, and the total score range varies between 0 and 63
[20]. The concurrent validity of this test was estimated at 0.79, and its retest reliability was reported to be 0.67 (Beck, 1988)
. In Iran, the reliability of this test has been estimated at 0.84 through the coefficient of internal consistency based on Cronbach's alpha; moreover, the correlation obtained from the method of halving the pair and individual questions was determined at 0.70
[19]. In this study, Beck's Depression Test obtained an internal consistency at 0.85 using Cronbach's alpha coefficient.
Beck Anxiety Test
This 21-item test was developed in 1988. The items are rated on a 4-point Likert scale of 0=not at
all, 1=mild, 2=moderate, and 3=severe (3). Accordingly, the score range is from 0 to 63, and the total score varies between 0 and 63 [20]
. The internal consistency of this scale was reported to be 0.92, and its retest reliability was estimated at 0.75 (Beck, 1988)
. Furthermore, the reliability of this test was determined at 0.78 using Cronbach's alpha in Iran, and a favorable validity was obtained in this regard. Psychometric characteristics of Beck's Anxiety Test regarding the age and gender of the Iranian population have revealed validity, reliability, and an internal stability alpha of 0.72, 0.83, and 0.92, respectively
[21]. In this study, the internal consistency of Beck's Anxiety Test was obtained at 0.86 using Cronbach's alpha coefficient.
Pieces of music used in this study
Pieces of music used in this study to ameliorate anxiety and depression included Master Lotfi's solo and Farhang Sharif spring, as well as Payvar's anger and reconciliation and Hossein Alizadeh's morning greeting
Arrangement of songs
The arrangement of the songs included 1) Lotfi's Tar solo, 2) Farhang Sharif spring, 3) Hossein Alizadeh's morning greeting, and 4) Master Payvar's anger and reconciliation
.
The Waltz and Basel method was used to evaluate the content validity index of the music-therapy package
.
Accordingly, all items related to the music therapy package obtained content validity
. Table 1 tabulates the content of the intervention sessions.
