breast cancer, tumor, hem, hemato-oncological malignancies
BREAST CANCER, TUMOR, DELETION
For the analysis, the differences in the outcomes of T1 and T2 were calculated to retain the target variable change. These changes were compared between IG and CG. Questionnaires with missing values were removed from the evaluation. Thus, outcomes were analyzed by pair-wise deletion. Shapiro-Wilk and Levene tests were used to test for normality and homogeneity. Wilcoxon Rank Sum Tests for independent samples were used where the assumptions were not met. Furthermore, we explored intervention effects within specific subgroups, that is, gender (female, male), therapy status (currently in therapy, currently not in therapy), therapy goal (curative, palliative), and the 2 most common tumor entities (hemato-oncological malignancies (hem), breast cancer (bc)). Additionally, the influence of therapy adherence on the outcome was explored within the IG with unpaired 2-sample Wilcoxon Rank Sum Tests comparing the outcomes of participants who watched all the video sequences and participants who watched only part of the videos. All statistical analysis was performed using IBM SPSS Statistics (International Business Machines Corporation Statistical Package for Social Sciences), Version 26, R (Software Version 4.1.1), and RStudio (Version 1.4.1717).
