Rely for search procedures and results
Rely for study coding
Have a second rater conduct inclusion/exclusion review using your operationalized criteria for a minimum of 20% of the articles within each phase of the search (e.g., title/abstract search, full inclusion review, extended search, inclusion/exclusion for extended search).
Then choose a reliability index (see Kazdin, 2011 for more information) and calculate reliability for each phase of the search.
If you have a disagreement, revisit those aspects of the study summaries and make changes to the table to more accurately summarize the studies.
