A large and growing number of investigators have examined the factors that increase or decrease the likelihood of influence effects between peers, and these findings are essential toward the development of more precise, targeted intervention efforts. At this stage, current knowledge of moderators is largely descriptive; future examination of these variables should be directed by developmental psychopathology theories. For example, it is likely that research from the past decade has collectively identified variance related to a broader vulnerability construct that renders youth more or less susceptible to influence.
