The integrative literature review has many benefits to the scholarly reviewer, including evaluating the strength of the scientific evidence, identifying gaps in current research, identifying the need for future research, bridging between related areas of work, identifying central issues in an area, generating a research question, identifying a theoretical or conceptual framework, and exploring which research methods have been used successfully. The 5-stage integrative review process includes (1) problem formulation, (2) data collection or literature search, (3) evaluation of data, (4) data analysis, and (5) interpretation and presentation of results. Maintaining scientific integrity while conducting an integrative research review involves careful consideration to threats to validity. Strategies to overcome these threats are reviewed. The integrative review methodology must involve detailed and thoughtful work, the outcome of which can be a significant contribution to a particular body of knowledge and, consequently, to practice and research.
