Background: Previous negative experiences (NEs) during the process of blood donation can resultin increased stress and is indicated by blood pressure and pulse rate, at a subsequent donation. Thepresent study investigated the effect of attitude and anxiety in 1st time and regular blood donorswith or without any previous NE on the pre-donation blood pressure and pulse rate. Materials andmethods:  Pre-donation blood pressure and  pulse rate  in  1st  time  and  regular donors weremeasured. The attitude and anxiety were evaluated using a questionnaire and the relationship with aprevious NE  was  assessed. Its  effect on  the  blood pressure and  pulse rate  was  subsequentlyevaluated. The  study was  a  between-subjects, observational design. Results:  Of  the  total  200donors, 165 were males. 54 donors showed signs of anxiety whereas 33 donors had a previous NE.11 donors (22.44%) who had a previous negative experience showed raised blood pressure whereas9 donors (18.36%) with a previous negative experience showed a raised pulse rate. Both effective(-0.293) and cognitive (-0.0159) attitudes were negatively correlated with anxiety and were foundto  be  statistically significant. Conclusion:  No  significant  association was  seen  in  a  donor whoexperienced a  negative  experience in  a  previous visit  with  raised pre-donation blood pressurehowever, was significantly associated with a raised pulse rate. Moreover, anxiety and increased bloodpressure, and increased pulse rate were assessed in first-time donors and it was seen that first-timedonors especially showed raised blood pressure and pulse rate.
