Abstract Background and Objectives Considering the lower-than-expected participation of women in donating blood, it is necessary to encourage them to do so. In this regard, the preparation of appropriate and effective trainings requires the identification of effective factors in women blood donation. This study has investigated the relationship between the constructs of the theory of planned behavior and injection anxiety in female students of Isfahan University of Medical Sciences. Materials and Methods This descriptive-analytical study was conducted with the participation of female students of Isfahan University of Medical Sciences in 2022. Six hundred and twenty-three students were selected by stratified multi-stage quota sampling method and the data related to the constructs of the theory of planned behavior and trypanophobia were collected through an electronic questionnaire with SPSS/20 software and coefficient tests. Pearson correlation and linear regression were used for data analysis.
Results The results showed that 114 female students (18.3%) had a history of donating blood. There was a direct relationship between the constructs of awareness, mental norms, perceived behavioral control and attitude with the intention to donate blood; injection anxiety had an inverse relationship with the intention to donate blood (p ≤ 0.001).
Conclusions The theory of planned behavior can be a suitable model for conducting interventions to encourage women to donate blood; on the other hand, using different educational programs to reduce injection anxiety and treat anemia in women in order to increase blood donation seem necessary.
