The Rating of methodological quality of studies on PsycBITE

Assessing the quality of scientific literature is an important part of evidence-based practice as well as good research. PsycBITE offers an important contribution to this process.

How are the studies on the PsycBITE database rated? The PEDro-P and RoBiNT scales

Each trial is rated using a scale depending on the type of study design used. Randomised controlled trials and non-randomised controlled trials (including pseudo-randomised controlled trials) are rated using the PEDro-P Scale (PDF 93Kb). Single-case design studies are rated using the RoBiNT scale (Tate et al., 2013). Systematic reviews and case series are not rated for their methodological quality. Please find more information under Research Design and Rating. To ensure consistency with rating, two independent reviewers rate the trials that are included on PsycBITE. These ratings are conducted by members of the PsycBITE team, as well as volunteer raters from any allied-health or medical discipline. All raters have undergone training and assessment to qualify as a rater for PsycBITE. As a volunteer rater, you are a member of the PsycBITE Rater Network. If you would like to become a member of the PsycBITE Rater Network, please contact us.
It is important to note that each rating is based on information that has been explicitly stated in the text of the article. For example, if on a literal reading of the trial report it is impossible to establish whether a particular criterion is satisfied, it cannot receive a point for this criterion. Therefore, it is possible that a low rating may reflect the absence of detail in the report rather than the quality of the study.
