The nature of the relationship between communication behavior and research productivity is examined in this report. The purpose of the study was to attempt to explain variance in scientists' and scholars' research productivity using a variety of predictors. Data for the study were collected on questionnaires sent to 662 persons selected from membership lists of nine organizations in the communication research field and 517 persons from the National Science Foundation's "National Register of Scientific and Technical Personnel" (1966). The strongest predictor was found to be the extent of utilization of interpresonal contact with other researchers. Other consistent predictors were impersonal contact, number of professional memberships, level of education, recency of highest degree, and attendance at conventions. The major implication of the study is that research productivity increases with increased facilitation of interpersonal contact among researchers. In Appendix A the questionnaire items and response percentates are presented. Appendix B gives the data in table form. Appendix C is a factor analysis of 55 variables. (CC)
