title: Development and validation of the biobanking attitudes and knowledge survey-Spanish (BANKS-SP).
abstract: Few research studies with non-English-speaking audiences have been conducted to explore community members' views on biospecimen donation and banking, and no validated Spanish-language multi-scale instruments exist to measure community perspectives on biobanking. This study describes the development and psychometric properties of the Biobanking Attitudes aNd Knowledge Survey-Spanish (BANKS-SP). The BANKS was translated into Spanish using the Brislin method of translation. Draft BANKS-SP items were refined through cognitive interviews, and psychometric properties were assessed in a sample of 85 Spanish-speaking individuals recruited at various community events in a three county area in central west Florida, USA. The final BANKS-SP includes three scales: attitudes, knowledge, and self-efficacy; as well as three single items, which evaluated receptivity and intention to donate a biospecimen for research. The final Cronbach's alpha coefficients for the two scales that use a Likert response format indicated adequate internal consistency (attitudes, α = .79; self-efficacy, α = .91). Intention to donate blood and intention to donate urine were positively correlated with attitudes, self-efficacy, and receptivity to learning more about biobanking (all p's < .001). BANKS-SP-Knowledge was not statistically significantly correlated with other BANKS-SP scales or single items measuring intention to donate a biospecimen for research and receptivity for learning more about biospecimen research. The BANKS-SP attitudes and self-efficacy scales show evidence of satisfactory reliability and validity. Additional research should be conducted with larger samples to assess the BANKS-SP instrument's reliability and validity. A valid and reliable Spanish-language instrument measuring Spanish-speaking community members' views about biobanking may help researchers evaluate relevant communication interventions to enhance understanding, intention, and actual biospecimen donation among this population.
