Assessment of gender differences in letters of recommendation for pharmacy residency applicants

Letters of recommendation (LORs) are highly regarded components of pharmacy residency applications, as they provide insight into an applicant's character and capabilities. In other medical fields, differences in language have been reported for letters written for female and male applicants; however, data on gender differences in LORs for pharmacy residency applications are currently lacking.

LORs for applicants to our institution's postgraduate year 1 pharmacy residency program for the 2019-2020 academic year were extracted and processed by a natural language processing service. Words within 18 categories were identified and counted for each LOR. Total word count was also compared.

Of the 473 LORs included for analysis, 320 (67.7%) were written for female applicants and 153 (32.3%) were written for male applicants. Approximately two-thirds of all writers were women for both female and male applicants. In comparing letters for women and men, there was a statistically significant difference in the percentage of LORs that contained terms in categories described as gendered, solitary/reserved, and desire. There was no statistically significant difference in total word count or in the presence of words in other categories such as grindstone, standout, agentic, or communal. When controlling for grade point average, writer gender, duration that the writer knew the applicant, and the writer's professional position, there were no changes to the statistical findings.

Letters written for female and male applicants were largely similar with regard to length and word categories utilized. While no clear gender bias was found when evaluating pharmacy residency LORs, writers must continue to assess their implicit biases and how those biases might affect a candidate's application.
