Peer review of PCORI-funded research helps make sure the report presents complete, balanced, and useful information about the research. It also confirms that the research has followed PCORI’s Methodology Standards. During peer review, experts who were not members of the research team read a draft report of the research. These experts may include a scientist focused on the research topic, a specialist in research methods, a patient or caregiver, and a healthcare professional. Reviewers do not have conflicts of interest with the study.
The peer reviewers point out where the draft report may need revision. For example, they may suggest ways to improve how the research team analyzed its results or reported its conclusions. Learn more about PCORI’s peer-review process here.
In response to peer review, the PI made changes including
- Justifying the inclusion of a large number of measures in the study to evaluate study outcomes by citing the lack of “gold standard” measures for individuals with serious mental illness. The investigators further explained inconsistencies between the outcomes reported in the final report and those listed in their ClinicalTrials.gov record
- Completing sensitivity analyses comparing study outcomes with and without imputing values for missing data. The investigators initially justified the lack of imputation, despite the high attrition rate, by stating that their final sample size still met power estimates. The results from imputing study outcomes did not differ from the originally reported analyses
- Explaining the rationale for comparing the 6-month scores for the waitlist control group to the 6-month scores for the intervention group. The reviewers were concerned that the 6-month scores for the waitlist group might be contaminated with information about the intervention, so the researchers also compared the waitlist baseline scores with the 6-month intervention scores, and reported the differences in a footnote
