This study aims to develop a competency measurement scale for assessment of ward nursing managers from a nursing standpoint in order to facilitate collaboration between nurses and care workers in wards containing long-term care beds (medical and nursing care beds). First, we clarified the concept of measurement through a preliminary survey and prepared question items for a provisional scale. Next, using standard deviation and the item-total correlation test, 34 items were identified for a prototype "Manager Competency Measurement Scale." We then asked nurses to cooperate in a survey regarding this prototype and received responses from 853 nurses (64.6% acceptable response rate). The responses were subjected to descriptive statistics, factor analysis, test-retest reliability and internal consistency (Cronbach's alpha) analyses, and a criterion-related validity analysis against related scales. As a result, reliability, validity, and temporal stability were confirmed for the entire scale and for 5 subscales extracted from the 34 question items: "conflict management," "communication in the ward," "development of trust," "understanding of expertise," and "efforts to share goals." The Cronbach's alpha values ranged from 0.72 to 0.82 (p<0.01), and similar results were produced in test–retest reliability. Based on these results, the developed scale can be used for self-assessment by ward nursing managers striving to ensure that nurses and care workers collaborate in a ward that contains long-term care beds and features a complicated personnel structure, as well as in fact-finding related to the state of collaboration in the ward.
