Masser, Barbara M., White, Katherine M., Hyde, Melissa K., Terry, Deborah J., & Robinson, Natalie G. (2009) Predicting blood donation intentions and behavior among Australian blood donors : testing an extended theory of planned behavior model. Transfusion, 49(2), pp. 320-329.
BACKGROUND: Donor retention poses a significant problem to blood collection agencies around the world. Previous research using an augmented Theory of Planned Behavior (TPB) approach has demonstrated that attitude, subjective norm, self-efficacy, moral norm, anticipated regret, donation anxiety from prior blood donations and self-identity as a blood donor predicts experienced donors’ intentions and that intentions, self-efficacy, moral norm, and anticipated regret may impact upon people’s actual blood donation behavior -- STUDY DESIGN AND METHODS: Established blood donors (N = 263) completed questionnaires assessing standard TPB constructs, anticipated regret, moral norm, donation anxiety, and self-identity as a blood donor. Three months later, a second questionnaire assessing blood donation behavior in the intervening three months was mailed and returned by 182 donors -- RESULTS: Using structural equation modeling, the final augmented TPB model provided an excellent fit to the data and included a direct path from intention to behavior and indirect paths to behavior through intention for attitude, self-efficacy and anticipated regret. Moral norm, donation anxiety and donor identity indirectly predicted intention through attitude. In total, 51% of the variance in donors’ attitudes, 86% of variance in donors’ intentions, and 70% of the variance in donors’ behavior was accounted for in the final model -- CONCLUSION: An augmented TPB framework proved efficacious in determining the predictors of the intentions and behavior of established blood donors. Further, this framework highlighted the importance of considering in the future how donors’ motivations for donating blood may evolve as a function of the number of prior donations -- KEYWORDS: Theory of Planned Behavior, intentions, established donors, moral norm, anticipated regret, donation anxiety, self-identity
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
