Development of Nursing Practice Scale of Cancer Pain Management and Examination of Reliability and Validity

ABSTRACT

The aims of this study were (1) to develop and validate the scale to measure evidence-based nursing practice in cancer pain management and (2) to identify associated factors. We developed potential items based on the 2014 version of Japanese Clinical Guidelines for Cancer Pain Management and administered anonymous questionnaire for 189 oncology nurses in a designated cancer center. We conducted a re-test to test reliability.167 nurses participated in the study. As a result of item analysis and exploratory factor analysis, we developed a nursing practice scale of cancer pain management and its shortened version. This scale consists of 1 domain 50 items The Cronbach’s α coefficient showing internal consistency was 0.98 (shortened version 0.88). The intra-class correlation coefficient of reliability was 0.52 (shortened version 0.77). Concurrent validity was confirmed by the correlation between the total score of the whole scale and the total score of the practice of palliative care, knowledge, difficulty, self-confidence scale. We concluded that this scale was valid and reliable. Factors related to the nursing practice of cancer pain management were years of experience in cancer nursing, opportunities of postgraduate education, and satisfaction with postgraduate education. This scale can be used for evaluation of daily clinical practice and practice evaluation after educational efforts such as cancer pain nursing training.
