Research on supportive communication has been concerned with two primary classes of dependent variables. Message evaluations refer to judgments about the supportive message and/or the sender of that message, and message outcomes refer to cognitive, affective, and behavioral effects of messages. Most studies have utilized variables from one or the other class with less attention paid to the association between evaluations and outcomes. Indeed, there is a common assumption that message evaluations are a valid proxy for other outcomes of interest. This assumption is tested empirically in this article. Results from two studies show that (1) evaluations of messages mediate the effect of message quality on outcomes and (2) degree of message scrutiny moderates this mediating effect by altering the degree to which message quality influences evaluations. We use a dual-process theory of supportive message outcomes as the framework for interpreting supportive message effects and for examining the link between message evaluations and outcomes.
