Consider the relationship between impulsivity,social isolation,and mental health,and consider the three following potential ways to study these associations.In one hypothetical study,a researcher considers whether impulsivity predicts poorer mental health,but only at high levels of social isolation.In a second study,a researcher tests whether social isolation explains why impulsivity predicts poorer mental health.In a third study,a researcher tests whether social isolation predicts both impulsivity and poorer mental health.Consider how social isolation is being modeled in each of these studies,and choose the correct description from the options below.The first study models social isolation as a ________;the second study models social isolation as a ________;and the third models social isolation as a ________.
A)moderator;mediator;confounding
B)suppressor;mediator;moderator
C)moderator;confounding;suppressor
D)confounding;mediator;moderator

In the first study, social isolation is being modeled as a moderator, as the hypothesis is that the effect of impulsivity on mental health is dependent on the level of social isolation.
In the second study, social isolation is being modeled as a mediator, as the hypothesis is that social isolation explains why impulsivity predicts poorer mental health.
In the third study, social isolation is being modeled as a moderator, as the hypothesis is that social isolation predicts both impulsivity and poorer mental health.
