X: independent variable; Y: outcome variable; M: mediator; c: path from X to Y; c′: path from X to Y accounting for M.
Bold type face indicates significant mediation effect (confidence intervals do not include 0; Preacher and Hayes, 2008) and after FDR correction (P FDR < 0.05).
All tests of mediation are one‐tailed and bias‐corrected.
