Interpretation of interaction effects

Post by Choukri »

Hi everyone,
Please I need your help
Could you help me how to interpret these results

In my study, X is the independent varables, and Y is the dependent variabl, while VS and CI are the moderating variables.

Direct effect
X --> Y = 0.31

Interaction effect
VS*X --> Y = -0.11
CI*X --> Y = 0.09

I will be very grateful if someone helps me

The effect of X on Y at the mean of VS and CI is 0.31.
With increasing VS, this effect is reduced (by -0.11 for each standard devaiation of VS) and with increasing CI, this effect is enhanced (by 0.09 for each standard deviation of CI).

Hi,

I suggest to test three ways interaction:
1. Consider the equation which is input into the model (unlike the two-ways interaction).
2. Do not use the procedure Baron and Kenny

Hi,

Thank you Professors for the response,

Dr. Jan-Michael Becker, could I say in this point that VS has a negative effect on the relarionship between X and Y; and CI has a positive effect on the X-Y relarionship?

Direct effect
X --> Y = 0.31

Interaction effect
VS*X --> Y = -0.11
CI*X --> Y = 0.09

Thank you again Professor.
