Mediational analysis- is Sobel test appropriate?

29 February 2020 1 8K Report

I would like to conduct a mediational analysis to see whether the motivation to lose weight (binary variable) mediates the relationship between mental health symptoms at baseline and BMI at follow up. Would the Sobel test be appropriate and if not what is the best test to use?

Thank you in advance.

You should use SEM mediation analysis with R or AMOS, which allows you to determine fit indices that explain the validity of the proposed global model beyond the path values, making it the most robust method for mediation analysis.
