Note. X and M are equally stable at 0.50, the c path is 0, and the y path is 0.36 for all conditions. All path coefficients are fixed. Type I error rates outside of the range [0.025,0.075] are italicized, those over are boldfaced. CSM = cross-sectional mediation; SM = sequential mediation; DM = dynamic mediation; CLPM = cross-lagged panel mediation; MCSM = multilevel cross-sectional mediation; MLM = multilevel longitudinal mediation.

^aMCSM is the generating model for MCSM and CSM analysis. MCSM uses all 100 people and all 100 time points for analysis. ^bMLM is the generating model for MLM, SM, DM, and CLPM analysis. MLM uses all 100 people and all 100 time points for analysis.
