This two-group clinical trial was approved by the Ethics Committee of Zahedan University of Medical Sciences under the code Ir.zaums.REC.1396.115. It was carried out on all mothers of children with leukemia who had referred to the Hematology Ward of Ali ibn Abi Talib Hospital in Zahedan in 2017.
Since there was no similar study in this area in Iran, the sample size was estimated at 80 (40 for each group) by using G*-Power software and considering the Cohen’s effect size of 0.5 (α = 0.05 and β = 0.8) and a 15% attrition rate.
Convenience sampling was employed to select the mothers of children with leukemia according to the inclusion criteria. The criteria for entering the study were as follows: (1) willingness and informed consent to participate in the study, (2) being the primary caregiver of the child, (3) making a diagnosis at least for three months confirmed by a specialist, (4) no history of participation in educational programs on resilience or similar concepts, and (5) mother’s mental and physical health to the extent that the research procedures are not restricted. On the other hand, the exclusion criteria included the reluctance to continue the intervention or the occurrence of any incident such as death, migration, and discontinuation of the treatment of the child such that it might cause the mother to be absent from more than two training sessions.
Among the mothers meeting the inclusion criteria, those who completed the informed consent form entered the study. Subsequently, participants completed a demographic form and the Connor-Davidson Resilience Scale (CD-RISC). The subjects were then randomly assigned to the control and experimental groups using permuted (quadruple) blocks with the help of Random Allocation software.
In the first stage of the intervention, the peer educator was selected and educated. One mother who was the primary caregiver during treatment and had the following characteristics was chosen as the peer educator: (1) willingness and informed consent to take part in the intervention; (2) a minimum education of high school diploma; (3) the ability to train and communicate with others; (4) being a local person with fluency in Persian; (5) living in Zahedan; and (6) having successful experiences of the treatment process of the child. Eventually, a mother with a bachelor’s degree whose child had successfully reached the final phase of chemotherapy (i.e., maintenance) was chosen.
To prepare the peer educator, three instructional sessions, each lasting one hour (
25), were held in which brainstorming and question-and-answer methods were deployed. In these sessions, the need for organizing such an intervention, its stages, the method of implementation, and the training program were fully explained. The purpose of the sessions was to review experiences and information, modify them based on accepted scientific principles, and ultimately prepare the mother-instructor for peer education. The task of the peer educator who led the peer group was to manage the meetings by guiding the mothers toward the desired subject, presenting her own individual experiences, encouraging mothers to participate in discussions, and finally summing up previously raised topics (
26). The ability of the peer educator to learn accurate information was evaluated through question and answer and role play (
27).
In the second stage of the intervention, the experimental group was divided into subgroups of 10 people. The peer educator was then asked to discuss the materials and direct the group in a friendly and favorable environment based on previous instructions. The researchers were in charge of providing the content, scheduling, and monitoring the sessions.
No intervention was performed for the control group, and these individuals received conventional care and training. It should be noted that in order to prevent the control group from having contact with the experimental group and thus, reduce the possibility of information exchange, the control group was first selected and their related data were collected. In fact, the intervention started upon the discharge of the children of mothers in the control group.
The materials of the peer education program, based on the study of Hosseini Ghomi and Salimi Bajestani and the approval of a psychiatric nurse consultant, were taught to each subgroup in five sessions (
13). Each session began by clarifying its goals. Then, the peer educator undertook the task of teaching and sharing her information, experiences, and social backgrounds. At the end of each session, the peer educator summarized the materials discussed and answered the questions. At the end of the training program, an educational pamphlet was provided to the mothers. The content of the training sessions is recapitulated in
Table 1. Based on previous studies in this field (
28), each subgroup was exposed to one session a day for five days, each session lasting 1.5 hours. The sessions were held in the training room of the hematology ward of Ali ibn Abi Talib Hospital when the children of the experimental group were still hospitalized. Immediately after the intervention and two months later, CD-RISC was completed for both experimental and control groups again.
| Session | Details |
|---|
| Session 1 | The researcher and participants getting acquainted with each other; explaining the study objectives and the manner in which the intervention was to be implemented to gain the confidence of the participants; explaining the role of the researcher, the group leader, and other participants; introducing the general framework of the topics; defining resilience and the characteristics of resilient people such as happiness, wisdom and insight, humor, empathy, rational adequacy, purposefulness in life, and stability; providing solutions and experiences about the challenges and difficulties posed by the child’s illness; elaborating on problem-solving solutions and increasing personal adaptation; encouraging mothers to share their experiences |
| Session 2 | Teaching and sharing experiences of the use of internal protective factors (optimism and self-esteem) and external protective factors (family, friends, other people, and social support systems) |
| Session 3 | Training different ways of cultivating resilience and expressing one’s experiences, communicating with others, accepting new conditions, hoping for the future, and employing various strategies to reduce stress |
| Session 4 | Continuing to discuss resilience strategies: promoting self-awareness, self-confidence, and self-care |
| Session 5 | Summing up, conclusion, and performing the post-test |
Data collection tools consisted of the CD-RISC (2003) and a demographic questionnaire covering mother’s age, child’s age, child’s gender, duration of leukemia, mother’s occupation, residence, mother’s marital status, and mother’s education. Aiming to measure the level of resilience in different populations, CD-RISC has 25 items that are scored based on a 5-point Likert scale (from rarely true = 0 to true nearly all of the time = 4). The tool has five subscales: the concept of personal competence (eight items), trust in one’s instincts and tolerance of negative affect (seven items), positive acceptance of change and secure relationships (five items), control (three items), and spiritual influences (two items). The score of each subscale was obtained by summing up the score of its items and the total score of resilience was the sum of the score of all items, ranging from 0 to 100 (
14). The validity of this tool was confirmed in Iran by Mohammadi, with Cronbach’s alpha being 89.0 for the total scale (
29). In the present study, Cronbach’s alpha of CD-RISC was 78.0.
The data were analyzed by SPSS version 16 using descriptive and inferential statistics at the significance level of P < 0.05. Descriptive statistics (including frequency, mean, and standard deviation) were used to describe the demographic characteristics, as well as the main variables of the study. Then, the Kolmogorov-Smirnov test was employed to determine the data distribution. Other tests used included the chi-square (Fischer’s exact test), independent t-test, repeated measures ANOVA, and Bonferroni post hoc test.
