Hi,
I have data where participants were assigned to treatment and control groups and four waves four measurements. I wanted to ask if the following model is correct.
DATA: FILE IS longtitudinal_mediation.dat;
VARIABLE: NAMES ARE
Group, m1, m2, m3, m4, y1, y2, y3, y4;
USEVARIABLES ARE Group, m1, m2, m3, m4, y1, y2, y3, y4;
MISSING ARE ALL (99);
ANALYSIS: ESTIMATOR=ML;
Model:
M2 on Group m1;
m3 on Group m2;
m4 on Group m3;
y2 on y1 Group m2 m1;
y3 on y2 y1 Group m3 m2 m1;
y4 on y3 Group m4 m3 m2 m1;
Model Indirect:
y4 ind m3 Group;
y3 ind m2 Group;
output: cinterval sampstat STD;
Also, how do I add an additional mediator to the model? (serial longitudinal mediation?) |
