A study was conducted of the expectations and perceived communication between field and supervisory personnel in the Michigan Cooperative Extension Service. Each agent in the sample completed a 209-item questionnaire dealing with his communication with his supervisor, and each supervisor completed ten such questionnaires for each of his ten field agents. This resulted in 200 questionnaires giving matching information about 100 pairs or dyads. Similarities and differences and agents' and supervisors' backgrounds are analyzed. Supervisors perceived less frequent overall communication than did the field agents. Field agents perceived significantly less communication about personal matters and new ideas than did their supervisors. Significantly more supervisors wanted more communication about the existing program. Field agents perceived significantly more of the communication that they received as being initiated by the supervisor. A high level of similarity of orientation between supervisors and field agents was found at both the agreement and accuracy levels. But between 1/3 and 1/2 of the dyads showed disagreement or misunderstanding. Similarity of orientation was found to be associated with dyadic satisfaction and interpersonal perceptions, but other factors contribute to these states. Implications of the study are discussed, and references are provided. (KM)
