![]() ![]() Narrative reviews also appear popular among both authors and readers, and it is plausible to assume that they exercise an enormous influence among doctors in clinical practice and research. found that they constitute the largest share of all text types in medicine and they concluded that they “remain the staple of medical literature”. Narrative review articles are common in the medical literature. In editorial decision-making, SANRA may complement journal-specific evaluation of manuscripts-pertaining to, e.g., audience, originality or difficulty-and may contribute to improving the standard of non-systematic reviews. We recommend rater training based on the “explanations and instructions” document provided with SANRA. ![]() Further field testing, particularly of validity, is desirable. SANRA’s feasibility, inter-rater reliability, homogeneity of items, and internal consistency are sufficient for a scale of six items. The intra-class correlation coefficient (average measure) was 0.77 (inter-rater reliability). Corrected item-total correlations ranged from 0.33 (item 3) to 0.58 (item 6), and Cronbach’s alpha was 0.68 (internal consistency). The mean sum score across all 30 manuscripts was 6.0 out of 12 possible points (SD 2.6, range 1–12). Raters confirmed that completing the scale is feasible in everyday editorial work. The revised scale was tested by the same editors (blinded to each other’s ratings) in a group of 30 consecutive non-systematic review manuscripts submitted to a general medical journal. ![]() For all items, we developed anchor definitions and examples to guide users in filling out the form. The six items which form the revised scale are rated from 0 (low standard) to 2 (high standard) and cover the following topics: explanation of (1) the importance and (2) the aims of the review, (3) literature search and (4) referencing and presentation of (5) evidence level and (6) relevant endpoint data. We deleted an item which addressed a manuscript’s writing and accessibility due to poor inter-rater reliability. MethodsĪ team of three experienced journal editors modified or deleted items in an earlier SANRA version based on face validity, item-total correlations, and reliability scores from previous tests. In response to this gap, we developed SANRA, the Scale for the Assessment of Narrative Review Articles. However, unlike systematic reviews and randomized controlled trials (RCT) articles, for which formal instruments exist to evaluate quality, there is currently no instrument available to assess the quality of narrative reviews. Narrative reviews are the commonest type of articles in the medical literature. ![]()
