title: Development and validation of the biobanking attitudes and knowledge survey (BANKS).
abstract: BACKGROUND
  No validated multiscale instruments exist that measure community members' views on biobanking and biospecimen donation. This study describes the development and psychometric properties of the English-language BANKS (Biobanking Attitudes and Knowledge Survey).
  
  
  METHODS
  The BANKS was created by item generation through review of scientific literature, focus groups with community members, and input from a community advisory board. Items were refined through cognitive interviews. Content validity was assessed through an expert panel review. Psychometric properties of the BANKS were assessed in a sample of 85 community members.
  
  
  RESULTS
  The final BANKS 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. Cronbach α coefficients for two scales that use Likert response format indicated high internal consistency (attitudes: α, 0.88; self-efficacy: α, 0.95). Content validity indices were moderate, ranging from 0.69 to 0.89. Intention to donate blood and intention to donate urine were positively correlated with attitudes, knowledge, self-efficacy, and receptivity to learning more about biobanking (P values range from 0.029 to <0.001).
  
  
  CONCLUSIONS
  The final BANKS shows evidence of satisfactory reliability and validity, is easy to administer, and is a promising tool to inform biospecimen research. Additional studies should be conducted with larger samples considering biospecimen donation to further assess the reliability and validity of the instrument.
  
  
  CONCLUSIONS
  A valid and reliable instrument measuring community members' views about biobanking may help researchers evaluate relevant communication interventions to enhance understanding, intention, and actual biospecimen donation. A Spanish-language BANKS is under development.
