Evaluation methods for assessing professional skills and knowledge has become very important in this age of cooperation and coordination of health-social professionals. We have developed conceptual framework as well as practical methods to assess professional skills and knowledge for health-social professions' interrelationship. The purpose of this study is to clarify the visiting nurses' self evaluation of their professional skills and knowledge related to care management. Subjects (238 visiting nurses) and controls (894 other kinds of health-social professionals) were asked to answer a questionnaire on "Evaluation of professional skills and knowledge", which had 3 mainstreams--basic skills and knowledge, management skills and knowledge, and general evaluation. Each subscale included essential items for professional skills and knowledge, covering all health-social professions. Results of investigation showed that more than 98.2% of visiting nurses agreed to the framework of this evaluation and items. Differences in evaluation according to kinds of profession were few. The structure of items related to professional knowledge and skills were clearly shown by cluster analysis, and coefficient alphas were more than 0.95 for each subscale. In conclusion, this evaluation would be practical for visiting nurses. "Evaluation of professional skills and knowledge" will be useful for visiting nurses to facilitate their coordination with other kinds of professionals on the job and they will also be able to utilize it in educational situations.
