OBJECTIVE: The effects of methods used to improve the interrater
reliability of reviewers' ratings of manuscripts submitted to the Journal
of the American Academy of Child and Adolescent Psychiatry were studied.
METHOD: Reviewers' ratings of consecutive manuscripts submitted over
approximately 1 year were first analyzed; 296 pairs of ratings were
studied. Intraclass correlations and confidence intervals for the
correlations were computed for the two main ratings by which reviewers
quantified the quality of the article: a 1-10 overall quality rating and a
recommendation for acceptance or rejection with four possibilities along
that continuum. Modifications were then introduced, including a multi-item
rating scale and two training manuals to accompany it. Over the next year,
272 more articles were rated, and reliabilities were computed for the new
scale and for the scales previously used. RESULTS: The intraclass
correlation of the most reliable rating before the intervention was 0.27;
the reliability of the new rating procedure was 0.43. The difference
between these two was significant. The reliability for the new rating scale
was in the fair to good range, and it became even better when the ratings
of the two reviewers were averaged and the reliability stepped up by the
Spearman- Brown formula. The new rating scale had excellent internal
consistency and correlated highly with other quality ratings. CONCLUSIONS:
The data confirm that the reliability of ratings of scientific articles may
be improved by increasing the number of rating scale points, eliciting
ratings of separate, concrete items rather than a global judgment, using
training manuals, and averaging the scores of multiple reviewers.
