Background: Chemotherapy exposure is an occupational hazard that affects the health of oncology nurses and other health care workers. The health complications of chemotherapy exposure among the health care workers are severe and include infertility, congenital anomalies, genotoxicity, and the increased risk to develop cancer. One important factor influencing the exposure among oncology nurses is the inadequate level of adherence to chemotherapy safe handling guidelines. Purpose: The purpose of this dissertation research was to develop and psychometrically test an instrument that measures oncology nurses’ health behaviors determinants with regard to the adherence to the guidelines when handling chemotherapy. Methods: An integrative review of the literature were conducted to identify the current literature related to the factors that affect chemotherapy exposure among nurses who handle them. This review revealed the need to develop an instrument which has evidence of reliability and validity and measures the factors that influence oncology nurses’ health behaviors when handling chemotherapy. After identifying this gap, the items of a new instrument, the Oncology Nurses Health Behaviors Determinants Scale, were developed by the investigators based on the Health Belief Model. The instrument’s content validity was then judged by a group of seven experts using a cross-sectional study design with a qualitative component. Then, the instrument was psychometrically tested using a cross-sectional study design with a sample of 125 oncology nurses. Results: The Content Validity Index (I-CVI) at the item level and for the total Scale Content Validity Index (S-CVI) were calculated. Twenty-eight items in the final instrument met the required level of content validity (CVI=0.83). Four additional items were retained due to conceptual significance. Two items were added based on experts’ suggestions. The instrument version after the content validity contained 34 items. The total S-CVI=0.85. Based on the psychometric testing results, five items were deleted from the instrument. The internal consistency of the subscales was acceptable to very good (Cronbach’s alpha between 0.70-0.88). Validity testing through factor analysis and regression model testing provided evidence of construct validity for this instrument. Factor analysis revealed a six-factor structure with good conceptual meaning. The results of the regression model showed that all the six subscales explained 17.1% of the oncology nurses’ health behaviors when handling chemotherapy. Besides that, oncology nurses’ self-efficacy was a significant individual predictor of the oncology nurses’ health behaviors when handling chemotherapy. Conclusion: The Oncology Nurses Health Behaviors Determinants Scale demonstrates evidence of reliability and validity. This instrument may be useful in practice settings to assess factors that influence oncology nurses’ health behaviors when handling chemotherapy. This instrument might also serve as a valuable outcome measure for future interventions designed to foster more adherence to the guidelines when handling chemotherapy among oncology nurses who handle chemotherapy.
