Gender-inclusive language, such as the Swedish pronoun hen, may aid in breaking a binary notion of gender and avoid sexism. The present study followed the implementation of a gender-inclusive third-person pronoun singular (hen) in Swedish in two surveys with representative samples in 2015 (at the time when hen was introduced in the official Swedish dictionary; N = 1212) and in 2018 (N = 2009). The surveys comprised measures of attitudes toward, and use of, hen as well as possible predictors such as area of residence, age, preferred pronoun, political orientation, and interest in gender issues. Results showed that attitudes toward hen became more positive and that use of hen increased between 2015 and 2018. About half of the population used hen in their communication in 2018, which is a 14-percentage-point increase from 2015. Younger age, she or hen as preferred pronoun, political left-wing orientation, and interest in gender issues predicted a more positive attitude and a more frequent use. Furthermore, the positive change between 2015 and 2018 was larger among younger people, indicating that hen will remain in the Swedish language. The present research is unique in that it follows a gender-fair language initiative during its implementation in representative samples, thereby providing insights for social movements aiming for gender-fair language. We also discuss the theoretical implications of a gender-inclusive pronoun in comparison with past studies on gender-fair language.

性别包容性语言，例如瑞典语代词母鸡，可能有助于打破性别的二元概念并避免性别歧视。本研究在 2015 年（在瑞典官方词典中引入母鸡时；N = 1212）和 2018 年的两次具有代表性样本的调查中，跟踪了瑞典语中性别包容的第三人称代词单数 (hen) 的实施情况(N = 2009)。调查包括对母鸡的态度和使用的测量以及可能的预测因素，如居住地区、年龄、首选代词、政治取向和对性别问题的兴趣。结果显示，2015 年至 2018 年间，人们对母鸡的态度变得更加积极，使用母鸡的情况有所增加。 2018 年约有一半的人口在交流中使用母鸡，比 2015 年增加了 14 个百分点。年龄较小，她或母鸡作为首选代词、政治左翼倾向和对性别问题的兴趣预示着更积极的态度和更频繁的使用。此外，2015 年和 2018 年之间的积极变化在年轻人中更大，表明母鸡将继续使用瑞典语。本研究的独特之处在于，它在代表性样本的实施过程中遵循性别公平语言倡议，从而为旨在实现性别公平语言的社会运动提供见解。我们还讨论了与过去关于性别公平语言的研究相比，性别包容代词的理论含义。2015 年和 2018 年之间的积极变化在年轻人中更大，表明母鸡将继续使用瑞典语。本研究的独特之处在于，它在代表性样本的实施过程中遵循性别公平语言倡议，从而为旨在实现性别公平语言的社会运动提供见解。我们还讨论了与过去关于性别公平语言的研究相比，性别包容代词的理论含义。2015 年和 2018 年之间的积极变化在年轻人中更大，表明母鸡将继续使用瑞典语。本研究的独特之处在于，它在代表性样本的实施过程中遵循性别公平语言倡议，从而为旨在实现性别公平语言的社会运动提供见解。我们还讨论了与过去关于性别公平语言的研究相比，性别包容代词的理论含义。
