Abstract
INTRODUCTION: Nurses are the first line of healthcare professionals who provide ongoing care to donors and their families. The intention of nurses to sign the organ donor card and the factors affecting it are important in the field of organ donation. The aim of the present study was to predictors of intention to sign an organ donor card among clinical nurses based on the expanded organ donation model. MATERIALS AND METHODS: This cross-sectional study was conducted among 264 nurses from five educational and therapeutic centers in Hamadan, in 2023. Participants were recruited by convenience sampling method and surveyed on being a donor and their perceptions about signing the donor card. Data were collected using a valid and reliable self-administered questionnaire. The Pearson correlation coefficient and linear regression were used to assess the relationship between variables. SPSS software version 26 was used for data analysis. The significance level was considered to be p < 0.05. RESULTS: The mean (SD) age of participants was 35.6 (7.8). The predictors of behavioral intention to sign organ donor card were perceived control (β = 0.245, p < 0.001), anticipated regret (β = 0.226, p < 0.001), descriptive norms (β = 0.205, p = 0.001), mass media sources (β = -0.195, p = 0.002), subjective norms (β = 0.156, p = 0.007), and knowledge (β = -0.140, p = 0.010). The EODM constructs were able to explain 41.2% of the variance in nurses' behavioral intention to receive an organ donation card. CONCLUSION: This study elucidates the complex interplay of factors influencing nurses' behavioral intentions to sign an organ donor card, providing critical insights that can inform future interventions and policy decisions. The findings highlight perceived control as the most important predictor, suggesting that increasing individuals' confidence in their ability to make informed decisions about organ donation could significantly increase participation rates.
