If you want to refer to several works that have the same first author and year, you need to separate these references in the in-text citations. You then need to write out as many authors as necessary to separate the references.

Example:

• Kapoor, Bloom, Montez, et al. (2017)
• Kapoor, Bloom, Zucker, et al. (2017)

If only the last author separates the references, do not write et al. after:

• Hasan, Liang, Kahn, and Jones-Miller (2015)
• Hasan, Liang, Kahn, and Weintraub (2015)

APA Style: Citing Multiple Works With Three or More Authors and the Same Date
