\Manuscript characteristics associated with the altmetrics score and social media presence: an analysis of seven spine journals

BACKGROUND CONTEXT: Impact factor, citation rate, and other traditional measures of scholarly impact do not account for the role that social media has in the dissemination of research. The Altmetric Attention Score (AAS) quantifies the active online presence of individual articles on various platforms (eg, Twitter, Facebook). PURPOSE: We sought to better understand the factors associated with greater online attention and AAS in seven spine journals. STUDY DESIGN/SETTING: Cross-sectional study. PATIENT SAMPLE: No patients were included in this study. We analyzed 380 articles in seven major spine journals. OUTCOME MEASURES: Extracted manuscript characteristics included AAS; number of Twitter, Facebook, and news outlet mentions; number of citations, references, academic institutions, and authors; and sample size, geographic region, subject of study, and level of evidence. METHODS: All original scientific manuscripts published in the official January, February, and March 2017 issues of Spine, The Spine Journal, Spine Deformity, Journal of Neurosurgery-Spine, Clinical Spine Surgery, Global Spine Journal, and European Spine Journal were identified. The correlation of AAS and number of citations was determined by Spearman's Rho (r) correlation coefficient. Manuscript factors associated with AAS were determined by a multivariable linear regression analysis. RESULTS: A total of 380 manuscripts were included in the analysis. The average AAS across all seven journals was 4.9 (SD: 19.4; Range: 0-356), with the highest average AAS reported for The Spine Journal at 8.0 (SD: 13; Range: 0-60). There was a weak, positive correlation between AAS and number of citations (r =.32; p<.05); this relationship was individually present for four out of the seven included journals. In addition, number of references was associated with higher average manuscript AAS (beta: 0.16 [95% CI: 0.002-0.32]; p<.05). No manuscript characteristics were associated with lower AAS. CONCLUSIONS: Our analysis of seven spine journals revealed a weak, positive correlation between AAS and number of citations. Number of references was associated with higher AAS. We believe these findings may be useful to authors seeking ways to maximize the impact of their research. (C) 2020 Elsevier Inc. All rights reserved.
