Moderator Variables and Different Types of Predictability: Do You Have a Match?

Prior research has demonstrated the utility of moderator variables in improving the congurence between: (a) self- and peer ratings of traits and (b) self-reports of internal dispositions and actual behavior. There are, however, certain points of disagreement and confusion about how moderator variables affect these two types of predictability. The present study sought to bring some clarity to this research area by addressing two interrelated issues: (a) Are these types of predictability related and (b) what variables moderate each? Subjects filled out scales that measured the moderator variables that have been previously studied and provided information on both types of predictability. It was found that the first type of predictability was unrelated to the second. The greatest self-peer rating congruence was found among subjects who had good social communication skills. The greatest internal disposition-actual behavior congruence was found among subjects who were unwilling, unable, or both to change their behavior in response to situational demands, and being aware of, attentive to, and placing importance on the inner-self was related to both types of predictability. The discussion focused on the manner in which moderator variables (especially those that concern social skills) will affect each type of predictability and the need to match moderator variables to specific types of predictability.
