Description: The original 16-item EBP Beliefs scale has been shortened to a 3-item scale to measure a person’s beliefs about the value of EBP and ability to implement it. Participants respond on a 5-point Likert type scale with responses ranging from 1=Strongly Disagree to 5=Strongly Agree. Higher summed scores indicate stronger EBP beliefs.
Psychometrics: Factor analysis supported the construct validity of each of the three shortened scales as all item intercorrelations were greater than 0.40 and KMO values were 0.62 to 0.74. The shortened scales Cronbach αs’ were 0.81 for the EBP Beliefs Scale, 0.89 for the EBP Implementation Scale, and 0.87 for the EBP Culture and Readiness Scale. The three shortened EBP scales had acceptable convergent validity (r = 0.42 – 0.72) for the correlations between the shortened and longer scales). (Melnyk, et al., 2021)
