An instrument was designed to measure patient health outcomes of nursing care based on the Roy Adaptation Framework. The tool was designed to assess the health outcomes of adult cancer patients on an extended course of chemotherapy treated in an in- or outpatient setting. Patient health outcomes affected by nursing care relate to infection, nausea, vomiting, stomatitis, body regard, activity level, and the patient's attitude toward his or her own level of functional effectiveness. The instrument has two parts, a nurse form and a patient questionnaire. There are five scales on the patient questionnaire: a Nausea and Vomiting Scale (3 items); a Body Regard Scale (10 items); an Anxiety Scale (9 items); and two Functional Effectivenss Scales, one dealing with an attitude dimension (4 items) and one dealing with an activity dimension (3 items). The nurse form records important patient background variables. This paper summarizes the steps the authors used to develop and test both the reliability and the validity of the items on the patient and nurse forms. Explication of the developmental stages in tool development makes the process of clinical tool development more accessible to practicing nurses.
