Abstract
ObjectiveTo develop and validate a questionnaire which evaluates the blood donors’ satisfaction.BackgroundIn Malaysia, blood procurement relies mainly on voluntary non-remunerated donors. Hence, it is important to ensure the satisfaction of the blood donors in order to increase retention.MethodsThis study was conducted among blood donors who attended blood donation and understood the Malay language. Non-Malaysian and illiterate donors were excluded. The questionnaire was developed by the transfusion medicine team. Content validity was established by content reviewers, while face validity was examined in the cognitive debriefing stage. For the 18-item questionnaire, 90 respondents were required based on the 1:5 ratio. A retest was performed in two weeks’ time.ResultsOne hundred and thirty-seven participants responded in the first phase, while 103 responded after two weeks. The five domains were: technical, interpersonal, accessibility/ convenience, physical experience and overall satisfaction. The Kaiser-Meyer-Olkin (KMO) value was 0.896, with significant Bartlett’s Test of Sphericity (P < 0.001). The factor loadings ranged from 0.729 to 0.953. The Cronbach alpha values of the five domains ranged from 0.814 to 0.955 and the intraclass correlation coefficient ranged from 0.663 to 0.847.ConclusionThe Malaysian blood donor’s satisfaction (M-BDS) questionnaire is a reliable and valid tool suitable for the assessment of blood donor’s satisfaction in blood donation centres.

Summary
The need for blood and blood products is increasing annually worldwide, especially in low and middle-income countries [1]. Out of the 117.4 million blood donations collected globally, 42% are collected in high-income countries, inhabited by 16% of the world’s population. Based on a sample of 1,000 people, the blood donation rate was 32.6 donations in high-income countries, 15.1 donations in upper-middle-income countries, 8.1 donations in lower-middle-income countries and 4.4 donations in low-income countries [2]. Growing demand in blood supply is a global phenomenon. In Canada, it was reported that blood demand outpaced the supply due to ageing and increase in demand [3]. In Malaysia, blood procurement relies mainly on voluntary nonremunerated donors. It is important to ensure the satisfaction of the blood donors in order to increase retention
