A study was conducted to address the communication concerns of health care professionals. To identify the communication activities and problems of health care communication situations, the Communication Activity Questionnaire (CAQ) was administered to the personnel of 18 human service agencies involved with care of the physically and mentally ill or with health education. The questionnaire is designed to elicit information concerning the communication activities most important and problematic in fulfilling the respondents' job requirements. The 138 practitioners who returned questionnaires identified the following skills as important in their jobs: relationship building, listening, routine information exchange, motivating, and oral reporting. Giving and soliciting feedback also emerged as important skills for employees in health care facilities. Although the CAQ does not measure writing skills and problems, the results of the study suggested that poor writing skills might also be the source of some of the more serious problems perceived by health care employees.
