Hello dear STATALIST forum,
I hope you have started the new year well and can assist me with a problem.
I am currently working on a project in which I am trying to observe the impact of child poverty on work values. My focus is on mediating effects through personality and parenting style.
All my variables are ordinal (quasi-metric) scaled. I have calculated a Structural Equation Model (SEM) with multiple mediators (Big 5 & Supp. Parenting Scale) and interpreted it using the MEDSEM command.
During a presentation in a team meeting, it was suggested that I should try to replicate the same relationships using the KHB method.
The results differ significantly. While occasional mediation effects (according to Baron/Kenny and Zhao, Lynch & Chen) are visible in the SEM model, this is not the case in the KHB Decomposition.
I have the following questions:
Best regards,
Marcel

I have the following questions:
- What can account for the differences?
- Is there an error in my SEM or KHB input?
- Which results should I report? Is there a good reason to prefer SEM/MEDSEM results over KHB results?
Best regards,
Marcel
