moderatorとmediator

私的メモです。
どうも時々混乱するし，
論文とか読んでいて何それ検索しようという方もいるでしょうから。

A moderator model is operative when the strength or direction of a relation
between two variables varies as a function of a third variable, called the
moderator variable. The moderator need not affect the outcome variable
itself. Rather, it represents a set of conditions that qualify the relation
between two or more other variables.

A mediational model is operative when one variable affect a second (outcome)
variable only indirectly, through an intermediate step or process, represented
by a third variable, called the mediator variable. The mediator variable is
simultaneously conceived as being a consequence of the first variable and a
cause of the outcome variable. In a completely mediational model, the entire
effect of the first variable on the outcome variable is translated through the
mediator variable.
