Abstract
ObjectivesAdherence by oncology nurses to chemotherapy safe handling guidelines is essential to prevent hazards of chemotherapy exposure. A review of the literature revealed the need for an instrument with evidence of reliability and validity to measure factors influencing adherence to safe chemotherapy-handling guidelines among oncology nurses. The purpose of this study was to psychometrically test the Oncology Nurses’ Health Behaviors Determinants Scale (HBDS-ON) that measures the mentioned factors. Data SourcesMethodological research of a quantitative cross-sectional survey design was used. The study surveys were administered by email to a sample of 108 oncology nurses. Cronbach alpha, item analysis, exploratory factor analysis using principal axis factoring, and convergence validity testing were used to test reliability and validity. ConclusionFactor analysis yielded six subscales, each having acceptable internal consistency reliability (Cronbach alpha between 0.70 and 0.88). The subscales included four oncology nurse health beliefs (perceived threat, benefits, barriers, and self-efficacy), cues to action, and personal protective equipment availability and accessibility. Convergence validity testing results support the Oncology Nurses Health Behaviors Determinant Scale (HBDS-ON) construct validity. Oncology nurses’ self-efficacy to adherence to chemotherapy-handling guidelines, the perceived barriers to adhere to chemotherapy-handling guidelines, and cues to action are associated with adherence to chemotherapy-handling guidelines. Implications for Nursing PracticeOncology nurses’ health beliefs, the cues to action, and personal protection equipment availability and accessibility are important determinants of nurses’ adherence to chemotherapy-handling guidelines. The HBDS-ON is an instrument that has evidence of reliability and validity and could be used in practice to measure these determinants.
