This quasi-experimental study was conducted from January 2012 to February 2013 (over 13 months). The sample size was 34 children with CRF and their parents in each of two groups (intervention and control) based on similar studies: d =. /7s2, α = 0.05, β = 0.2 (
14). The study was conducted at a pediatric nephrologist’s office. Ethical approval for this study was obtained from the research and technology deputy of the Isfahan University of Medical Sciences and the relevant authorities (391138). Children were selected from the office of the pediatric nephrologist by simple random sampling so that the first referring individual with the inclusion criteria was assigned to the intervention group and the second to the control group. This process continued until the desired number of participants was obtained for the two groups.
The inclusion criteria were: age 8-12 years, no previous kidney transplantation, the absence of other chronic diseases, the ability to comprehend the Persian dialect, no mental and psychological problems (by medical file and medical examination), the children’s and parents’ consent to participate in the study, and the parents’ ability to read and write. The exclusion criteria consisted of patient withdrawal from the study, movement, and events such as parents’ divorce and the death of the parents and/or siblings.
In this study, the family empowerment model was considered the independent variable, QoL the dependent variable, and the children’s age, gender, and education level, and parents’ place of residence the underlying variables. After the research purposes were explained to, and written consent was obtained from, the participants in both groups, the researcher administered the questionnaires for the pretest. The training sessions were then planned in coordination with the children and parents in the intervention group, and the pediatric nephrologist’s office was judged a suitable location for training and thus used to hold the sessions.
After the questionnaires had been filled out by the two groups, needs assessment sessions were held by the researcher for the intervention group, and the content of the empowerment program was developed after identifying the sources, limitations, and needs of the children and their parents. The content of the empowerment program was validated and confirmed by a number of experienced university teachers.
The codified program was then conducted in accordance with the steps of the empowerment model. Seven 45-minute sessions were carried out with the children based on their needs and tolerance, and three sessions in the form of group discussions were held with the parents. The family empowerment model was implemented in four organized steps. The training content was developed based on the results of the children’s and parents’ needs assessments, but the steps of the intervention were taken from a study by Alhani et al. (
15).
Training was implemented by the researcher in a group and face-to-face using speech, brainstorming, and educational aids, which included powerpoint presentations, movies, and educational replicas.
First step (knowledge enhancement): To enhance knowledge levels, several teaching aids and techniques were used. These included PowerPoint presentations, models, posters, team teaching, question-and-answer sessions, lecturing, and role-playing. For this, the participants were divided into 4-5 individual subgroups based on the type of disease, and were given teaching materials on kidney physiology and anatomy, etiology, symptoms, disease complications and prognosis, diet, laboratory tests and normal test values, methods of measuring weight, height, and blood pressure, and pharmacotherapy.
Second step (self-efficacy enhancement): To enhance self-efficacy, two sessions comprising demonstrations were held. In this method, explanations regarding the skills required for weight and blood pressure measurement were given, and these skills were taught to the children via demonstrations.
Third step (self-esteem enhancement through participatory training): In this step, the children were asked to encourage their parents to help them and to participate in training their parents to identify CRF-related issues. In this method, the children transferred the knowledge gained via the materials used in each group discussion as well as observation in the self-efficacy sessions to their parents. The children were given teaching cards of the materials for each session and were asked to give them to their parents to study. The parents then wrote down on paper the material from the cards, what they had learned from their children’s statements, and the relevant questions they had, and had their children give their written notes to the researcher in the next session.
Since the parents were likely to fail to study the cards, to appropriately understand the teaching materials through their children’s training, and hence to acquire adequate competency, the researcher invited them to three 45-minute training sessions on the disease course, diet, physical activity, pharmacotherapy, and disease complications. Two weeks after the last session, the researcher called all the participants to follow up on the implementation of the skills learned and to ensure that the taught materials were being implemented. Furthermore, the participants were given the researcher’s telephone number to ask any questions, if necessary.
Fourth step (process evaluation): To evaluate their knowledge, at the beginning of each session, the children were verbally asked some questions about the materials from the previous session. Self-efficacy was evaluated by asking the children to demonstrate or conduct two learned skills appropriately, while self-esteem was assessed by the level of the children’s cooperation in the participatory training when giving back the training cards comprising their parents’ notes. One month after the last intervention in the intervention group, the questionnaires were again administered to both groups. For ethical reasons, the handbook offered to the intervention group was also offered to the control group after the questionnaires had been filled out.
The data gathering instrument consisted of two sections: demographic characteristics and the questionnaire of core pediatric QoL Inventory (version 4). This questionnaire consists of 23 items, eight items for physical function and 15 items for psychosocial function (emotional, social, and school functions, each comprising five items).
The validity and reliability of the Persian version of this questionnaire have already been examined in Iran, and its content validity and Cronbach’s alpha were found to be 91.36% and 0.77, respectively (
16). The data were analyzed by descriptive and analytical (chi-square, paired t-test, and independent t-test) statistics in SPSS 20.A P value less than 0.05 was considered statistically significant.
