For my thesis I perform a moderation analysis via a hierarchical multiple regression analysis. More specifically, I want to investigate whether closeness in the parent-child relationship is a moderator in the association between conflict in the teacher-student relationship and the working memory performance of primary school children. In the analysis I work with two models (model 1 without interaction and model 2 with interaction as in this file: https://www.sheffield.ac.uk/polopoly_fs/1.885172!/file/90_Moderation_Meditation.pdf)
I would like a good example of another thesis or paper that works with the same analysis as me, but I haven't found one yet. In addition, with the second model I do not arrive at a statistically significant R2 change after adding the interaction. Can I continue with a moderation analysis or should I stop? According to my promoter, there are articles that use less strict criteria and that do continue with moderation analysis, but I haven't found them yet.
Thank you in advance!
