Statistical analysis
Correlations between the scores of the 4 scales were analyzed.
Subsequently, the correlation between the questionnaires (IES-R, PSS,
STAI-Y, PedsQL) and the variable “months”, the time between
oncological diagnosis to starting the study, was determined. Comparisons
between groups of parents were made using the Mann-Whitney U test for
non-parametric samples. Statistical analysis was performed using R 4.0.3
version.
