Background: The demand in biobanking for the collection and maintenance of biological specimens and personal data from civilians to improve the prevention, diagnosis and treatment of diseases has increased notably. Despite the advancement, certain issues, specifically those related to privacy and data protection, have been critically discussed. The purposes of this study are to assess the willingness of stakeholders to participate in biobanking and to determine its predictors.
Methods: A survey of 469 respondents from various stakeholder groups in the Klang Valley region of Malaysia was carried out. Based on previous research, a multi-dimensional instrument measuring willingness to participate in biobanking, and its predictors, was constructed and validated. A single step Structural Equation Modelling was performed to analyse the measurements and structural model using the International Business Machines Corporation Software Package for Social Sciences, Analysis of Moment Structures (IBM SPSS Amos) version 20 with a maximum likelihood function.
Results: Malaysian stakeholders in the Klang Valley were found to be cautious of biobanks. Although they perceived the biobanks as moderately beneficial (mean score of 4.65) and were moderately willing to participate in biobanking (mean score of 4.10), they professed moderate concern about data and specimen protection issues (mean score of 4.33). Willingness to participate in biobanking was predominantly determined by four direct predictors: specific application-linked perceptions of their benefits (β = 0.35, p < 0.001), issues of data and specimen protection (β = - 0.31, p < 0.001) and religious acceptance (β = 0.15, p < 0.05) and trust in key players (β = 0.20, p < 0.001). The stakeholders' willingness to participate in biobanking also involves the intricate relationships between the above-mentioned factors and other predictors, such as attitudes regarding technology, religiosity and engagement.
Conclusions: The findings of this study reaffirmed that stakeholders' willingness to participate in biobanking is a complex phenomenon that should be viewed from a multidimensional perspective. Stakeholder willingness to participate in biobanking is warranted when direct predictors (benefits, issues of data and specimen protection, religious acceptance, and trust in key players) as well as indirect factors are well accounted for.
