The Effect of the Educational Movie Shown to Pediatric Patients Receiving Intrathecal Chemotherapy Treatment on Pre-Procedure Fear and Post-Procedure Pain in Children

In this study, which is planned to be conducted in a randomized controlled experimental design, nonpharmacological methods (educational film shown with virtual reality goggles and cartoon shown with virtual reality goggles) applied to children aged 5-10 years who will receive intrathecal chemotherapy treatment before intrathecal chemotherapy treatment were evaluated. It is aimed to determine the effect on pre-procedure fear and post-procedure pain.

The study is planned to be conducted between November 2024 and November 2025. The population of the study will consist of children between the ages of 5-10 years who receive inpatient treatment in the Pediatric Hematology Clinic of Izmir Ege University Hospital (Health Practice and Research Center). Random sampling method and stratified randomization method will be used for sample selection. In the calculation of the sample size of the study, using G-Power 3.1.9.7 program; type 1 error (α) 0.05, power (1- β) 99% and Cohen's effect size (δ) 0.5, the sample size to represent the main mass was determined as 90 children for this study. However, when the dropout rate is set as 10% for data loss that may occur in the study, the minimum number to be reached for the study is targeted as 99 (intervention group 1 n=33, intervention group 2 n=33, control group n=33).

Research data will be collected after project acceptance. In all three groups, children and their parents will be informed before the study and their written and verbal consent will be obtained. Data will be collected by using the "Introductory Information Form", "Intervention Follow-up Form" and "Child Fear Scale (CFS)", "Wong Baker FACES (WB-FACES) Pain Rating Scale" and "Visual Analog Scale (VAS)" prepared by the researchers with the feedback of nurses, parents and children.

Statistical analyses will be performed using IBM SPSS Statistics 26.0 (IBM SPSS Statistics for Windows) package program. The significance level will be set as 0.05 in all analyzes. In the study, numerical data will be calculated using mean, standard deviation, median, minimum, maximum values and categorical data will be calculated using frequency and ratio values.

With the nonparametric Brunner-Langer model, the before-after change (group effect, before-after effect and interaction effect) of fear scores in the educational film, cartoon and control groups will be examined using R 3.3.1 software (R software, version 3.3.1, package: nparLD, R Foundation for Statistical Computing, Vienna, Austria; http://r-project.org). In order to visually examine this change, the 'relative effects' graph (since the nonparametric method is used) will be utilized.

When the Brunner-Langer model shows that the before-after change in the groups is not similar (interaction \< 0.05), the before-after comparison in each group will be made separately with the Wilcoxon sign test, and the differences between the groups will be compared with the Kruskal-Wallis test by taking the after-before difference. After Kruskal-Wallis, pairwise comparisons will be made with the Dunn test, and then Bonferroni correction will be used for p values. The agreement between the measurements of Nurses, Parents and Children will be evaluated by Intraclass Correlation (ICC) analysis.
