The Evidence-Based Practice Identification and Change (EPIC) intervention is a complex multifaceted knowledge translation strategy that combines the use of evidence and continuous quality improvement to change health care professional practices. However, there is no measure to evaluate the fidelity (degree to which the intervention was implemented as planned) of the EPIC intervention.
To examine the content validity of the Process Evaluation Checklist (PEC), a newly developed measure to assess the fidelity of the EPIC intervention.
Eight health care professionals with experience in the delivery of the EPIC intervention rated the importance/relevance of items in assessing the scale/subscales of the PEC. A content validity index was computed for each item (I-CVI) and for each scale/subscale (S-CVI) in the measure.
I-CVIs ranged from 0.6 to 1.0 and S-CVIs ranged from 0.3 to 1.0. Two items were eliminated, while nine items were retained.
Content validity of the PEC was established. The PEC will be used to evaluate the implementation fidelity of the EPIC intervention in future trials.
循证实践识别与改变（EPIC）干预是一种复杂的多方面知识转化策略，它结合了证据的使用和持续质量改进，以改变医疗保健专业人员的实践。然而，目前还没有衡量 EPIC 干预实施一致性（即干预按计划实施的程度）的方法。
检验新开发的评估 EPIC 干预实施一致性的工具——过程评估检查表（PEC）的内容效度。
8 名具有 EPIC 干预实施经验的医疗保健专业人员对评估 PEC 量表/分量表的项目的重要性/相关性进行了评分。为每个项目（I-CVI）和每个量表/分量表（S-CVI）计算了内容效度指数。
I-CVIs 的范围为 0.6 到 1.0，S-CVIs 的范围为 0.3 到 1.0。有两个项目被删除，保留了九个项目。
PEC 的内容效度得到了确立。PEC 将用于评估未来试验中 EPIC 干预的实施一致性。
