If I want to test whether there is a non-zero indirect pathway in the cross-lagged relationships from x --> m --> y, would the following syntax be correct? MODEL: %WITHIN% x m y ON TIME; m_to_m | m^ ON m^1; x_to_x | x^ ON x^1; y_to_y | y^ ON y^1; x_to_m | m^ ON x^1; y_to_m | m^ ON y^1; m_to_x | x^ ON m^1; y_to_x | x^ ON y^1; x_to_y | y^ ON x^1; m_to_y | y^ ON m^1; %BETWEEN% m x y; m_to_m-m_to_y; [x_to_m m_to_y] (A B); MODEL CONSTRAINT: NEW(IND); IND = A * B; Thanks! |

The syntax looks ok. But the topic of mediation with longitudinal data is complex. See for instance the Maxwell-Cole articles - 2007 in Psych Methods and 2011 in MBR. |

Excellent. Thanks Bengt, I'll have a look at those papers now |
