Background: Hospitalization induces anxiety and causes sleep disorders in children. Objective: This study aimed to examine the effects of listening and reading a tale on anxiety and sleeping onset time (SOT) among hospitalized children with fracture. Methods: This randomized clinical trial was conducted on 102 children with extremity fracture in Shohada Hospital of Tabriz in 2018–2019. Subjects were recruited consecutively and randomly allocated into three groups: control, storytelling, and simultaneous listening to and reading a tale. The data were collected using a demographic information questionnaire: questions on SOT, heart rate, and the Reynolds and Richmond Children's Anxiety Questionnaire. One-way analysis of variance, paired t-test, Chi-square and Fisher's exact test, and analysis of covariance were used to analyze the data. Results: Mean SOT, mean anxiety, and mean pulse rate did not significantly differ between the three groups at baseline. After the intervention, the mean SOT and mean pulse rate decreased significantly in all three groups (P < 0.001); however, the between-group differences were not statistically significant (P > 0.50). The mean manifest anxiety did not change significantly in any of the groups (P > 0.05). Conclusion: Storytelling had no effect on anxiety, heart rate, and SOT of children with fractures. Further studies can help determine the best method of storytelling for children with fractures.

| Introduction|| |
Illness and hospitalization could be the first crisis a child faces in life. In the United States, 5 million children are hospitalized annually. About 30% of children are hospitalized at least once during childhood, and 5% of them experience rehospitalization. Children's limited coping mechanisms make them vulnerable to crises created by disease and hospitalization. Hospitalization exerts tremendous psychological pressure on children, causes various coping problems, makes them anxious, and creates a threatening experience for them., Invasive procedures and surgeries are also extremely distressing for children. Preoperative anxiety is also associated with maladaptive behavior in children after surgery. Difficulty sleeping, falling asleep, waking up problems, and nightmares are all symptoms of anxiety. Sleep disorders are the most common behavioral problems in children and are associated with fatigue, anxiety, anorexia, muscle atrophy, immune system suppression, and delayed recovery. Sleep disorders impair children's mental and physical development by directly affecting protein synthesis, cell differentiation, and growth hormone secretion.,,
Accidents and bone fractures are the most important reasons for admitting children to hospitals., On average, 2.1% of children suffer fractures each year. Studies in Iran have shown that accidents are the leading cause of death, 16% of all injuries are caused by accidents, and fractures account for 81.1% of orthopedic injuries. Studies show that fractures of the lower and upper limbs are common in children., A study of 3579 cases of fractures in children under 12 years of age in Kermanshah, Iran, also reported that 65.4% and 31.2% of them had fractures of the upper and lower limbs, respectively. Due to the high proportion of children and adolescents in the total population, and the high prevalence of fractures among them, and due to the psychological, social, and financial consequences of fractures for patients and their families, it is necessary to provide quality care to children with fractures.
Surgery is one of the most common methods for treating fractures., Fractures and hospitalization affect patients' rest, reduce their mobility, disrupt their normal sleep patterns, and impair their sleep. It has been shown that 2%-25% of hospitalized patients and 54% of patients admitted to the intensive care units suffer from sleep disorders.
Nonmedical treatments for sleep disorders not only balance and enhance energy levels in the body but also increase health and comfort. Various methods such as touching, looking at or reading a book, listening to a story, playing games with parents, being cared for by parents, and spending time with children have been suggested to relieve pain and comfort children. Storytelling is one of the best among these treatments. Studies have revealed that listening to stories as a hobby creates comfort and removes tension before sleeping. It facilitates the secretion of serotonin in the brain and encourages the child to sleep. Storytelling is also favorite of children as a nonmedical, simple, affordable, and accessible technique. Numerous studies have been conducted on the effects of storytelling on anxiety and behavioral disorders in children. For instance, reading comic books has been shown to have positive effects on reducing anxiety after tonsillectomy, relieving pain in children with leukemia, and reducing physiological and social anxiety and distress in school-age children. However, no study has examined the effects of storytelling on anxiety and sleep quality in children with fractures. Considering the high prevalence of fractures in children and the effects of anxiety and sleep disorders on their growth and recovery, and the lack of studies on the effects of storytelling on sleep quality and anxiety in children, the question is whether listening to and reading stories can reduce anxiety and improve sleep in children with fractures?
This study aimed to compare the effects of listening to and reading a tale on anxiety and sleeping onset time (SOT) in hospitalized children with fractures.
| Methods|| |
Study design and participant
This study was a randomized clinical trial. The study was conducted in 2019 on 108 children aged 8–12 years with fracture admitted to Shohada Hospital of Tabriz, Iran. Inclusion criteria included a third- to sixth-grade student with limb fractures; an age of 8–12 years; parental consent; admission to the orthopedic department; being accompanied by the child's mother or a fixed person in the hospital; no medical diagnosis of sleep disorders, mental retardation, mental illness, and anxiety disorders; no visual or hearing problems; receiving no hypnotic medications; no invasive procedures between 9 p. m. and 11 p. m.; Iranian nationality; and the ability to read and write in Persian. Exclusion criteria included lack of child interest in participation and presence of multiple trauma. Exclusion criteria included lack of child interest in participation and presence of multiple trauma.
To determine the sample size, a pilot study was conducted with ten subjects and pulse rate was measured as a criterion for anxiety. The mean pulse rate of the participants was 90 ± 2.36 and changed to 85 ± 7.50. Then, with a type I error of 0.05, a type II error of 0.2, a S1 of 2.36, a S2 of 7.50, a μ1 of 90, and a μ2 of 85, the sample size was estimated to be 34 per group.
Data collection instruments
The data collection instrument consisted of three parts. The first part was a demographic data form and included questions on the children's age, gender, school grade, type of fracture, hospitalization history, normal nighttime sleep duration, the time between the beginning of the intervention and falling asleep, and the kinship of the accompanying person to the child. The second part was the Revised Children's Manifest Anxiety Scale (RCMAS). The RCMAS consists of 37 items, 28 of which assess anxiety and 9 of which assess the child's tendency to falsify responses. All items are answered on a yes/no scale. Each item expresses a feeling or action that reflects an aspect of anxiety. The overall score of this scale ranges from 0 to 28, and the cutoff point is 19. The higher the subject's score is above 19, the greater his or her anxiety. Taghavi and Alishahi translated the RCMAS into Persian, confirmed its content validity, and reported its test–retest reliability coefficient as 0.67. In the present study, we examined the reliability of the RCMAS in 30 children before the pilot study and its internal consistency was calculated as 0.83. In this study, the RCMAS was completed by the researcher. For this purpose, the researcher asked the child the items of the scale and recorded the answers on the scale.
The Sleep Disturbance Scale for Children (SDSC) was used to evaluate sleep disorders in children. This scale has 26 items in 6 subscales of sleep breathing disorders, difficulty in initiating and maintaining sleep, disorders of arousal, sleep–wake transition disorders, excessive somnolence disorders, and hyperhidrosis during sleep. All items are scored on a Likert scale from “1: never” to “5: always.” The overall score ranges from 26 to 130, and higher scores indicate more acute sleep disturbances. This scale is responded by parents. The validity of this scale was confirmed in Iran and its Cronbach's alpha was 82%. In the present study, we examined the reliability of the scale before the pilot study on 30 children and its Cronbach's alpha was 0.76.
Before starting the study, we prepared a permuted block randomization schedule using STATA14 software (Stata Corp., College Station, Texas 77845 USA), and 102 supposed participants were randomly allocated into 17 blocks of 6 to be assigned to 2 intervention groups and 1 control group, 34 in each group. Subjects with the inclusion criteria were identified consequently. After their eligibility was confirmed using the SDSC and RCMAS, the children were assigned to one of the three study groups according to the randomization schedule. All mothers of the children were instructed about the suitable sleeping time for children (i.e., 9:30 pm for children aged 8 and 9 years, and 10:00 pm for children aged 10–12 years).
Data were collected twice a day (evening and night) and during the first 2 days (i.e., admission day and surgery day). On the evening of the admission day, patients' pulse rates were measured using a pocket fingertip pulse oximeter. All patients received the prescribed analgesics at least 4–6 h before the intervention and at least ½ h before the measurement of anxiety and sleeping time. The RCMAS questionnaire was filled out except for the polygraph test questions, and the second visit was conducted between 9:30 and 10 pm that night to measure the time of falling asleep. The heart rate of all patients was measured for the second time on the evening of the second day (i.e., the day of surgery). Then, subjects in the storytelling group were given an mp3 player and headphones to listen to a CD of stories for 30 min (i.e., between 9 and 10 pm). While the subject listened to the story, the researcher was present in a corner of the room to record when they fell asleep. In addition to CD and the mp3 player, subjects in the second intervention group (i.e., the group in which storytelling and reading were done simultaneously) were provided with a storybook to read and look at while listening to the same story. The researcher was again present in the room to record the time of falling asleep. The control group received no intervention [Figure 1].
This study was approved by the Ethics Committee of Tabriz University of Medical Sciences (Ethics ID: IR.TBZMED.REC.1397.334) and registered in the Iranian Registry of Clinical Trials under ID IRCT: 20180622040189N1. Participation was entirely voluntary, all parents had declared their consent, and the purpose of the study had been fully explained to them. Id numbers were used to ensure the confidentiality of the subjects' names and data.
The data were analyzed using descriptive and inferential statistical methods. Statistical analysis was done by SPSS Statistics software (SPSS v.13.0; SPSS Inc., Chicago, IL, USA). Normality of numerical variables was checked by Kolmogorov–Smirnov test. Data were presented using mean, standard deviation, frequency, and percentage. One-way analysis of variance was used to compare the mean age, sleep duration, SOT, manifest anxiety, and pulse rate between the three groups. Paired t-test was also used for within-group comparison of the outcome variables. The Chi-square and Fisher's exact tests were used to compare the categorical variables between the three groups. Analysis of covariance was used to examine the potential effects of confounding variables such as group, age, gender, education, fracture type, sleep duration at home, and caregiver (mother or another person) in the hospital on the outcome variables. The significance level was set at <0.05.
| Results|| |
The mean age of children participating in this study was 9.23 ± 5.26 years, and 54.9% of them were girls. Most of the subjects were second-grade students (33.3%) and had been hospitalized for fracture of the radius bone (21.56%). The study groups did not significantly differ in terms of their demographic characteristics [P > 0.05, [Table 1]].

Mean SOT, mean anxiety, and mean pulse rate did not differ significantly between the three groups at baseline. After the intervention, mean SOT and mean pulse rate decreased significantly in all three groups (P < 0.001); however, the differences between groups were not statistically significant [P > 0.50, [Table 2]]. Mean manifest anxiety did not change significantly in any of the groups [P > 0.05, [Table 2]].

| Discussion|| |
In the present study, none of the interventions could affect the mean anxiety in children with fractures. Although pulse rate decreased slightly in all three groups at the end of the study, the mean pulse rate of the three groups did not differ significantly. In other words, neither listening to nor reading a story could reduce mean anxiety and pulse rate in children with fractures. These findings contradict the results of some previous studies that reported that storytelling reduced anxiety in hospitalized children.,,,, Some studies have shown that storytelling can effectively reduce hospitalization anxiety and behavioral disorders in children undergoing surgery., Ajorloo et al. also reported that storytelling reduced symptoms of anxiety in children undergoing chemotherapy. They concluded that storytelling, along with other psychological treatments, could be used to treat anxiety in children and particularly in children with health problems. Some studies also reported that storytelling was effective on aggression and withdrawal in preschool and school-age children. The contradictory results might be attributable to the fact that in the aforementioned studies, storytelling was conducted by the researcher and the live interaction between the researchers and the children might contribute to the positive effects., Furthermore, some studies conducted more sessions of storytelling. For example, Shabib Asl et al. conducted nine sessions of storytelling. In addition, most studies used storytelling in children with chronic disorders, whereas the present study focused on children with fractured limbs, which is an acute condition that occurred accidentally. Sekhavatpour et al. investigated the effects of reading comic books on posttonsillectomy anxiety in children aged 4–8 years. In their study, children read animated books on surgery and feelings before and after tonsillectomy for 30 min the night before surgery. They used RCMAS and Behavioral Disorders Inventory to measure anxiety after reading the story and 10 days after the surgery. Their findings revealed that reading animated illustrated books can effectively reduce anxiety and behavioral disorders in children after surgery. Again, this was not consistent with our results. The contradictory results may be attributed to the differences in interventions, study settings, children's ages, and other social and individual characteristics of the subjects studied.
Most children become anxious after being hospitalized. Fear of surgery also exacerbates their anxiety. This anxiety, in turn, disturbs their sleep patterns. Our findings showed that the SOT was significantly reduced in all three groups on the second night. Nevertheless, no significant difference was found between the mean SOTs of the three groups. Therefore, the reduction in SOT in the study groups could not be attributed to the intervention. It seems that the longest SOT occurred on the first night of hospitalization, and children fell asleep faster on the second night. This finding may be attributed to greater anxiety on the first night. Familiarity with the hospital environment and reduction of pain and discomfort on the second night may have reduced the children's anxiety, which in turn shortened their SOT. Nevertheless, earlier studies have shown that storytelling can reduce the SOT in children with chronic conditions. Another study in Turkey also reported that storytelling could improve sleep quality in hospitalized preschool children. Storytelling was also able to reduce pain in children with leukemia and improve sleep quality and sleeping habits in children with cancer who were undergoing chemotherapy., The conflicting findings of our study might be attributable to the differences in interventions and/or personal traits of the participants. For example, Yuniartini in Turkey conducted storytelling in preschool children on three consecutive nights. Some studies also conducted their intervention in children with chronic illnesses,,, while our participants were children with fractures, that is an acute problem with acute pain and discomfort. Furthermore, in most studies, storytelling was performed by the researcher or the patient's companion, whereas we used CDs, mp3 players, and headphones for this purpose. The lack of direct interaction between the storyteller and the child may have reduced the effectiveness of the intervention. However, the time we chose for storytelling may also affect the outcome. It is also possible that the time chosen for storytelling was inappropriate in the present study.
The present study was conducted merely on children hospitalized at Shohada Hospital of Tabriz, and its findings cannot be generalized to other children. Furthermore, the mental status of the children and the amount of their daily sleep might have influenced the outcome, but these variables were beyond our control. Furthermore, all children received an analgesic for pain, which could have influenced their sedation and the outcome of the study. We also used self-report instruments, which can increase the risk of social desirability bias.
| Conclusion|| |
In this study, storytelling had no effect on anxiety, heart rate, and SOT of children with fractures. Further studies can help determine the best method of storytelling for children with fractures.
