    Mediation analysis: 3 binary variables

    Hi, In my research I want to test a model with 3 binary variables: -X = year (year x, year x) -Y = volunteering (no, yes) -M = caregiving (no, yes) Since this is not possible with the Process macro, is it possible using the Baron and Kenny method? Thanks in advance!

    moderation/mediation repeated measures

    Hello everyone, I need help with interaction effects in multiple regression analysis. Study went like this: 120 participants solved 20 base-rate neglect tasks which all differed in ratio and congruence (mediators/moderators). They all solved statistical reasoning test (predictor). Correct...

    What's adequate sample size for single mediator model?

    Hi, I have set up a single mediator model to explain cases of COVID-19/million. I generated four regression equations using online software: 1) Cases COVID-19/million = .44234 x # Christians/10,000 + 2475.65082 2) # international adoptions made by a country between 1999 and 2016 =...

    Hello all, I was hoping someone could help my understand where a certain value comes from in my data output (using SPSS). I have performed a hierarchical multiple linear regression and the used PROCESS to find that my model has 2 predictor variables which both go through the 1 mediator variable...

    Is it possible to test this moderated multiple mediation model?

    Dear friends, For my masterthesis I want to test the following model. The effect of transformational leadership on learning motivation. Mediators are the three basal needs of the selfdetermination theory. So there are multiple mediations. These mediations are moderated by perceived workload...

    The difference of means as a fulfilled precondition for a mediation analysis

    The preconditions for a simple mediation analysis according to Hayes (2013) are statistically significant associations between X (the independent variable) and M (the mediator) as well as associations between M and Y (the dependent variable). In the case of a dichotomous independent variable...
