indicates a coefficient is significant at the .05 level using one-tailed t-test.

1

βa indicates the path coefficient from migration-induced stress to mediator.

2

βb indicates the path coefficient from mediator to depression.

3

βaβb indicates the indirect effect of migration-induced stress on depression via mediator.

the standard error of the mediation effect is estimated by the following formula given by Krull and Mackinnon (2001):

where βa and βb are unstandardized regression coefficients, and бβa and бβb are standard errors associated with βa and βb.
