Past research on organizational communication has not included systematic development of a measurement method that can be used to compare dimensions of communication within and across organizations. This research reports on initial attempts to develop such instrumentation. Seven samples, with a total number of over 1,200 respondents, were used to develop a 35-item questionnaire measuring 16 facets of communication.Communication has been the subject of considerable attention in organizational research. However, investigators often attach diverse labels to seemingly similar communication variables and similar labels to what appear to be different variables (Porter & Roberts, in press; Roberts, O'Reilly, Bretton, & Porter, in press). There has been no systematic development of instrumentation to measure communication variables in organizations. The present research begins to develop a standardized questionnaire that can be used to compare communication across organizations.A review of the organizational literature reveals that among the communication facets most frequently discussed and investigated are directionality of information flow (e.g., Graves, 1972), accuracy and distortion of information (Read, 1962;Wilensky, 1967), modalities used in transmitting information (Lawler, Porter, & Tenenbaum, 1968), and gatekeeping of information (Davis, 1968; O'Reilly & Roberts, in press;Rosen & Tesser, 1970). The communication literature not directly concerned with human behavior in organizations suggests additional aspects of communication that should be given greater attention in behavioral organizational research. These include overload (Porat & Haas, 1969) and satisfaction with one's communication (Lawler,
