I have to do mediation analysis for my research and my IV and DV are both continuous and mediator variable is ordinal (time spent on Instagram where categories are:
- less that 30 minutes a day
- 30 mins to 3h a day
- 3h to 6h a day
- more than 6h
I labeled this mediator as ordinal since measure differences in the categories aren't equal.
So I'm using SPSS and process macro only can be used if the mediator is continuous.
So what method do you suggest? I have been searching all over the internet and no answer found, so I'd really appreciate if you helped...
