APA Style (7th ed.)
Writers using APA Style must strive to use language that is free of bias and avoid perpetuating prejudicial beliefs or demeaning attitudes in their writing. . . . The guidelines for bias-free language contain both general guidelines for writing about people without bias across a range of topics and specific guidelines that address the individual characteristics of age, disability, gender, participation in research, racial and ethnic identity, sexual orientation, socioeconomic status, and intersectionality. (American Psychological Association, n.d., para. 2)
