Brief Summary:
Rh negative blood group is a rare blood group in China, as it only accounts for 0.3-0.4 percent of the Han population. Therefore, low inventory is often found in blood collection and supply agencies in many regions in China. In order to assess the effects of the gain-versus-loss framing message on blood donation among Rh negative donors, we designed two kinds of self-administered, standardized and structured questionnaires. In addition of the basic socio-demographic characteristics, one questionnaire includes the questions which survey the attitude of saving patients lives, and the other was to survey the attitude of preventing patients from death. The questionnaires were randomly sent to Rh negative blood donors.
