Abstract：
BACKGROUND: Implementation science helps generate approaches to expedite the uptake of evidence in practice. Mixed methods are commonly used in implementation research because they allow researchers to integrate distinct qualitative and quantitative methods and data sets to unravel the implementation process and context and design contextual tools for optimizing the implementation. To date, there has been limited discussion on how to ensure rigor in mixed methods implementation research.
OBJECTIVE: To present Particularity, Engagement, Actionable Inferences, Reflexivity, and Legitimation (PEARL) as a practical tool for understanding various components of rigor in mixed methods implementation research.
METHODS: This methodological discussion is based on a nurse-led mixed methods implementation study. The PEARL tool was developed based on an interpretive, critical reflection, and purposive reading of selected literature sources drawn from the researchers\' knowledge, experiences of designing and conducting mixed methods implementation research, and published methodological papers about mixed methods, implementation science, and research rigor.
CONCLUSIONS: An exemplar exploratory sequential mixed methods study in nursing is provided to illustrate the application of the PEARL tool. The proposed tool can be a useful and innovative tool for researchers and students intending to use mixed methods in implementation research. The tool offers a straightforward approach to learning the key rigor components of mixed methods implementation research for application in designing and conducting implementation research using mixed methods.
CONCLUSIONS: Rigorous implementation research is critical for effective uptake of innovations and evidence-based knowledge into practice and policymaking. The proposed tool can be used as the means to establish rigor in mixed methods implementation research in nursing and health sciences.

摘要：
背景：实施科学有助于生成方法，以加快在实践中的证据吸收。混合方法通常用于实施研究，因为它们允许研究人员集成不同的定性和定量方法以及数据集来解开实施过程和上下文，并设计上下文工具以优化实施。迄今为止,关于如何确保混合方法实施研究的严谨性的讨论有限。
目的：为了呈现特殊性，订婚,可操作的推论,自反性,和合法性（PEARL）作为一种实用工具，用于理解混合方法实施研究中严格性的各个组成部分。
方法：本方法讨论基于护士主导的混合方法实施研究。PEARL工具是基于解释性的，批判性反思，并有目的地阅读从研究人员的知识中提取的选定文献来源，设计和实施混合方法实施研究的经验，并发表了关于混合方法的方法学论文，实施科学，和研究严谨。
结论：提供了一项示例性的探索性序贯混合方法在护理中的应用，以说明PEARL工具的应用。对于打算在实施研究中使用混合方法的研究人员和学生来说，所提出的工具可以成为有用的创新工具。该工具提供了一种简单的方法来学习混合方法实施研究的关键严格组成部分，以便在使用混合方法进行设计和实施研究时应用。
结论：严格的实施研究对于将创新和循证知识有效地纳入实践和决策至关重要。拟议的工具可以用作在护理和健康科学的混合方法实施研究中建立严格性的手段。
