Hey there! I'm currently writing my BSc thesis, and I really need some help with SPSS and its interpretation.

I'm doing research into the effects of gamification (dichotomy) on learning, with motivation as a mediator, and gender; interest, and experience with gamification as moderators.

I was advised to apply PROCESS Model 5 to the data (a moderated mediation model), and run separate analyses for each moderator whilst including the others as covariates. Now, I thus have three different analyses, with three different models.

With regards to mediation - the effect of gamification on motivation remains the same in all three models, regardless of which moderator is applied. However, I cannot report the effect of motivation on learning, since in each model it is different - e.g. b = 0.074, t(57) = 2.29, p=0.202 OR e.g. b = 0.078, t(57) = 2.44, p = 0.018.

With regards to moderation, I assume I must only report the moderator and not the covariates..?

One last thing... How does it affect the data when my IV is dichotomous, and can I avoid this? The IV dichotomy was first coded as 0 - gamification and 1 - traditional education, and now I swapped them around. If I compare the data, some coefficients only gained a minus (-) sign in front of it, whereas e.g. 'constant' and moderators change numbers.

I would be so grateful if you could help me out, even if it's only an answer to one question!

Thanks, Alexandra
