Hello,
I have a question about which longitudinal mediation model would be the best for my study. My study contains two groups (A; intervention versus WL), two measures: a mediator (M) and an outcome measure (B) three measurement points (T0, T1, T2). I want to know if a change in M precludes a chance in B on the different time points.
Now I was wondering whether a cross lagged panel model or a latent change score model would be the best to use for this mediation. Would someone have any advice about this for me?
If the best solution is a latent change score model, does anyone maybe have any reccomendations for a tutorial on how to do this? (preferably in R).
(The study is about a parenting program which chances parenting skills (M) to reduce childerens externalizing behavior (B))
Thank you very much in advance!
Suzanne
