It's a moderated mediation multilevel model in a negotiation study. IV: essentialism (TrEnt) Mediator: Positive perception towards partner (PercPos) DV: negotiation outcome (FinalPt) Moderator: Cultural similarity (CultBg), a categorical between-level variable moderating IV-> Med. We are interested in the indirect effect of Moderator (1= dissimilar) on DV. Does this syntax below looks correct? Thanks!!
Define: Interact=CultBg*(TrEnt-3.37); ANALYSIS: TYPE IS TWOLEVEL RANDOM; MODEL: %WITHIN% TrEnt PercPos FinalPt; PercPos ON TrEnt; FinalPt ON PercPos; FinalPt ON TrEnt; %BETWEEN% CultBg TrEnt PercPos FinalPt Interact; PercPos ON TrEnt(a1); PercPos ON CultBg; PercPos ON Interact(a3); FinalPt ON PercPos(b1); FinalPt ON TrEnt; FinalPt ON CultBg; FinalPt ON Interact; MODEL CONSTRAINT: NEW(indb modval); modval = 1; indb=(a1+a3*modval)*b1; OUTPUT: TECH1 TECH8 CINTERVAL;
One more question: the goodness-of-fit indices of this model are not good, with CFI below 0.40 and RMSEA around 0.25. Do these indices matter in a multilevel model? If yes, how can i improve the model fit?
