ultilevel mediationmodel has been increasingly applied
in many fields, such as prevention, organizational,
education studies and health studies. This study will discuss
three widely used multilevel medication models (i.e., 1-1-
1, 2-1-1, and 2-2-1 models). This study will demonstrate
application of the popular 2-1-1 model in nursing study. Data
are simulated with three variables: nurse’s job satisfaction
(level-1 variable M
ij
), nurse’s intention to leave (level-1
outcome Y
ij
), and hospital work environment (level-2 variable
X
j
), where the sub-script i represents level-1 (individual)
unit and sub-script j represents level-2 (hospital) unit. The
hypothesis is that, the effect of the work environment (X
j
)
on nurse’s intention to leave (Y
ij
) is mediated by nurse’s job
satisfaction (M
ij
). However, the level-1 variable Mij could
serve as a mediator for both level-1 and level-2. The study
will show how to examine within-cluster, indirect effect, as
well as between-cluster indirect effect that is above and
beyond the within-cluster indirect effect. In addition, how to
control for covariates or confounding factors in the model
using residualized score will be discussed.
