- Abstract
Background and Objectives The aim of this study was to identify factors explaining the intention to donate blood. Materials and Methods A random sample of 4000 respondents drawn from the general population received a questionnaire by mail. This questionnaire assessed variables as defined by the most prominent social cognitive theories. Results Overall, the respondents expressed a neutral mean level of intention to give blood in the next 6 months (2·84 on a five-point scale); 56·2% had never given blood in the past. The variables explaining 74% of the variance of intention were: perceived behavioural control (β = 0·39; P < 0·001); factors facilitating taking action (β = 0·25; P < 0·001); anticipated regret (β = 0·16; P < 0·001); moral norm (β = 0·11; P < 0·001); attitude (β = 0·08; P < 0·01); level of education (β = −0·03; P < 0·05); and past experience in giving blood (β = 0·09; P < 0·001). Nonetheless, the predictive power of perceived behavioural control and moral norm was higher among the ever donors (both at P < 0·01) compared to the never donors, whereas the reverse was observed for attitude ( P < 0·05). Conclusions People's intentions are mainly determined by perceived barriers and obstacles regarding blood donations. This suggests that promotional strategies should focus on the elimination of barriers to action as well as the development of a higher perception of control. Also, messages should be adapted to the targeted population, based on their previous blood donation behaviour (i.e. never donors vs. ever donors).
