A convenience sample of 149 university students was surveyed on their attitudes and behaviors toward blood donation and with a scale of twenty four personality trait items.  These items reduced to a seven-factor structure.  The data were divided into two groups of high and low-likelihood of blood donation which were compared on factor means.  Differences were seen on the “Concern for Others” and the “Down to Earth” factors although not all items in a factor were different and differences were seen in some non-significant factors.  Applications of these finding are suggested.
