Impact factor metrics for The Gerontological Society of America's (GSA) journals have hit new highs, according to the latest issues of Journal Citation Reports, solidifying these publications’ status among the highest ranked in their field.

In Journal Citation Reports: Social Sciences Edition’s Gerontology category, The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences took the top spot on the list of 32 for the fifth consecutive year, and The Gerontologist and The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences climbed to take the fourth and fifth spots, respectively.

In Journal Citation Reports: Science Edition’s Gerontology and Geriatrics category, The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences ranked second and The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences ranked 17th out of 50. The Gerontologist is not ranked in this edition.

“The GSA journals continue to attract and publish the highest quality science in the field of gerontology,” said Peter A. Lichtenberg, PhD, chair of GSA’s Publications Committee. “That is a testament to the GSA leadership, our journal editors, and the partnership with our publisher, Oxford University Press.”

Impact factor is a measure of the frequency with which articles in a journal have been cited during the two preceding years. Journal Citation Reports, one of the most respected publication evaluation tools, is distributed by the Institute of Scientific Information, a division of Thomson Reuters.

A strong impact factor indicates the research published in a journal is being widely cited elsewhere, which is often a reflection of the quality of this research. This, in turn, encourages scholars to send their best material to the journal, thereby building on its status.

“The continued rise in influence and importance of the GSA's journals comes as no surprise,” said Oxford University Press President and Academic Publisher Niko Pfund. “As the challenges and opportunities of an aging population affect all spheres of society, the research conducted by GSA members and authors becomes increasingly vital. GSA’s careful stewardship and concerted efforts to disseminate influential scholarship are gratifyingly evident in the growth of its journals.”

The Gerontologist saw the greatest improvement over the past year, with its impact factor jumping from 2.772 in 2014 to 3.231 in 2015. During the same period, The Journals of Gerontology, Series A rose from 4.984 to 5.416 and The Journals of Gerontology, Series B increased from 2.852 to 3.213.

In The Journals of Gerontology, Series A, the most cited article in 2014 was “Rapamycin Extends Life and Health in C57BL/6 Mice” and the most cited article to date is “Frailty in Older Adults: Evidence for a Phenotype” from 2001. In The Gerontologist, the most cited article of 2014 was “What Does the Evidence Really Say About Culture Change in Nursing Homes?” and the most cited article to date is “Assessment of Older People - Self-maintaining and Instrumental Activities of Daily Living” from 1969.

In The Journals of Gerontology, Series B, five articles tied for the most cited in 2014: “Leisure Activity, Health, and Medical Correlates of Neurocognitive Performance Among Monozygotic Twins: The Older Australian Twins Study,” “Age and Interviewer Behavior as Predictors of Interrogative Suggestibility,” “Ups and Downs of Daily Life: Age Effects on the Impact of Daily Appraisal Variability on Depressive Symptoms,” “Implications of Marital/Partner Relationship Quality and Perceived Stress for Blood Pressure Among Older Adults,” and “Longitudinal Change of Self-Perceptions of Aging and Mortality”; the journal’s most cited article to date is “Self-Ratings of Health - Do They Also Predict Change in Functional Ability” from 1995.

Journal Citation Reports further included five-year impact factors for the three publications: 5.406 for The Journals of Gerontology, Series A, 3.856 for The Journals of Gerontology, Series B, and 3.380 for The Gerontologist. The five-year impact factor is the average number of times that articles from the journal published in the past five years have been cited in a Journal Citation Reports year (in this case, 2014). It is calculated by dividing the number of citations in a Journal Citation Reports year by the total number of articles published in the five previous years.

GSA membership includes access to the complete back catalog of The Gerontologist and both Journals of Gerontology, as well as another GSA journal, Public Policy & Aging Report. Members can view the articles online by logging in at

Oxford continually offers free online access to several highly-cited articles from each journal. The respective websites are,, and

GSA also is holding a symposium titled “How to Publish” at the Annual Scientific Meeting in Orlando, Florida, this November. It will provide an opportunity to meet with several editors of GSA’s journals and ask specific questions about getting published.


The Gerontological Society of America (GSA) is the nation's oldest and largest interdisciplinary organization devoted to research, education, and practice in the field of aging. The principal mission of the Society — and its 5,500+ members — is to advance the study of aging and disseminate information among scientists, decision makers, and the general public. GSA’s structure also includes a policy institute, the National Academy on an Aging Society, and an educational branch, the Academy for Gerontology in Higher Education.
