Despite the key role that hospital and home care nurses have in supporting family carers in transitional care, there is limited comparative information on their attitudes toward supporting family carers during care transitions. As part of a larger research project, we conducted a descriptive comparative study using a cross-sectional survey. Canadian nurses (105 hospital, 34 home visiting) completed a demographic questionnaire and the Families’ Importance in Nursing Care–Nurses’ Attitudes (FINC-NA) measurement tool. There were no statistically significant differences between hospital and home visiting nurses’ attitudes, which were positive about including families in care. Nurses who reported having a workplace philosophy or general approach to the care of family held more positive attitudes toward families than those who did not. This is important because positive attitudes are often linked to better communication with family carers and thus, better patient and carer outcomes. To our knowledge, only one Canadian master’s thesis has used this tool. Thus, this research furthers understanding of nurse attitudes within a Canadian context. Furthermore, this article adds to the literature by including suggestions for future research that are based in social psychological theories. Interdisciplinary knowledge can help pre- and postlicensure clinicians in advanced family nursing to better lever barriers and facilitators within family nursing practice.
