First citation with full name in the sentence For the first time you cite the CDC, use the full name (“Centers for Disease Control Prevention”) followed by its abbreviation (“CDC”) in the signal phrase that comes before the quote. Provide the date and page or paragraph number (“para.”) in parenthesis at the end of the sentence. Examples: According to the Centers for Disease Control and Prevention (CDC), “5.5 million visits to emergency departments in 2016 involved mental illness as the primary diagnosis” (2016, p. 24). According to the Centers for Disease Control and Prevention (CDC), there were “13.9 suicides per 100,000 people in 2016” (2016, para. 2). First citation without full name in sentence If you do not use the full name in the signal phrase, write out the full name in the parenthetical citation followed by its abbreviation in brackets. Example: In 2016 alone, there were “13.9 suicides per 100,000 people” (Centers for Disease Control Prevention [CDC] 2016, para. 2). Subsequent citations Once you’ve established the abbreviation for the CDC, you can use it for the rest of your paper in signal phrases or in parenthetical citations. Examples: According to the CDC, “3.9% of adults aged 18 and over” have experienced “serious psychological distress in the past 30 days” (2018, para. 4). With “3.9% of adults aged 18 and over” experiencing “serious psychological distress in the past 30 days,” it’s fair to say that the current system of treating stress, anxiety, and depression is inadequate (CDC, 2018, para. 4). Citing the date Always write the year of publication in the parenthetical citation. If two documents are published in the same year, differentiate them by adding “a” or “b” behind the date. Examples: According to the CDC, “3.9% of adults aged 18 and over” have experienced “serious psychological distress in the past 30 days” (2018a, para. 4). Last year alone, “56.8 million people visited physician offices for mental, behavioral, and neurodevelopmental disorders” (CDC, 2018b, p. 2).
