[Symposium scientific presentation] Purpose: Although evidence from studies has indicated that evidence-based practice (EBP) improves patient outcomes, there has been a lack of scales to measure implementation of EBP as well as factors influencing its implementation. Therefore, the purpose of this study was to determine the psychometric properties of two new scales, the EBP Beliefs Scale and the EBP Implementation Scale, which were developed from the Transtheoretical Model of Health Behavior Change.Methods: The scales were administered to 394 nurses from 5 states. The EBP Beliefs Scale is a 16 item instrument on which nurses are asked to respond to each item (e.g., "I believe that EBP results in the best care for patients," "I am clear about the steps of EBP") on a 5-point Likert scale that ranges from 1 (strongly disagree) to 5 (strongly agree). The EBP Implementation Scale is an 18 item instrument on which nurses are asked to respond to each item (e.g., "used evidence to change my clinical practice, critically appraised evidence from a research study") on a 5-point Likert scale by indicating how often in the past 8 weeks that they performed the item from a range of 0 meaning "0 times" to 4, meaning [Scientific session research presentation] While families play an important role in risk assessment and genetic testing decisions for individuals at risk for inherited breast/ovarian cancer syndrome, little research has been carried out with individuals and their family members together regarding how they influence each other in their decision making, cancer worries, and risk appraisals about cancer risk information. The purpose of this presentation is to describe the use of the Actor-Partner Interdependence Model of dyadic analysis that assesses the effect of cancer survivors and family relatives on each other in one single analysis. This approach provides a unique perspective of looking at both individual and family factors that influence both dyad members by taking into account both of the dyad's predictor variable scores on each of the family member's outcomes. A descriptive, cross-sectional design was conducted with 146 breast and/or ovarian cancer survivors and 146 unaffected female relatives (N=292). ">8 times."  Findings: Content and face validity for both scales was confirmed by 8 experts in EBP and 15 staff nurses. Construct validity was supported through factor analysis. Reliability coefficients for each of the scales exceeded 0.85. A significant correlation was found between EBP beliefs and implementation.Conclusions and Practice Implications: Both the EBP Beliefs and EBP Implementation Scales are valid and reliable instruments that can be used in clinical practice settings. Beliefs in EBP appear to be a critical factor in implementation, therefore, interventions to strengthen nurses? EBP beliefs (e.g., knowledge and skills building workshops) are likely to increase its implementation.
