Abstract
This study investigates the relation between indexes of the development of interpersonal construct systems and the qualities of messages generated in response to persuasive tasks within the context of an urban police force. Hypotheses assuming that length of service as a line officer would predict less developed construct systems, and that more developed construct systems would predict message strategies that acknowledge the unique qualities of receivers found general support. In addition, the possibility of further relations between length of service and message variables was explored, but no substantial evidence was found for such effects. These results show the importance of environmental influences on construct development, and suggest that interpersonal perception and message behavior functionally adapt to the needs of organizational participation.
