Published in JAMA, authors of the following study conducted a postal survey of individuals who had received new K08 and K23 career development awards from the National Institutes of Health from 2006-2009. Items on gender bias (both perceived in the environment and personally experienced), gender advantage, and sexual harassment were included in a larger questionnaire evaluating career and personal experiences. Additionally, those who had experienced sexual harassment in their professional careers were asked to report perceived effects on confidence and career advancement and specify the severity of the experience using 5 levels. Women were more likely than men to report perceptions and experience of gender bias in their careers. Women were more likely to report having personally experienced sexual harassment. Among women reporting harassment, 40% described more severe forms, 59% perceived a negative effect on confidence in themselves as professionals, and 47% reported that these experiences negatively affected their career advancement.
